The all new Doepfer Basic System is ready!

The brand new Doepfer Basic System is ready and offers a great way to learn and explore modular synthesizers, with all the necessary and exciting building blocks you need.

Check out the system here or read more about the idea and philosophy of the system below.

In 1995, Dieter Doepfer invented the Eurorack standard, and with it the modern modular synthesizer as we know it. The A-100 Analog Modular System was a true passion project, a way for Dieter to make available the legendary analog modular synthesizers that had first fascinated him in his youth (at that time only affordable to rock stars and academic institutions) in an affordable and accessible manner for the first time ever.

The Eurorack standard is an exceedingly minimal specification that only acts as a basic connective framework and leaves everything else up to the individual module designer. In response, in the past thirty years a thousand little flowers (modulargrid.net now lists almost fifteen thousand modules!) have bloomed, taking modular synthesis in all kinds of unexpected and novel directions. Over time, the format’s size and scope has increased far beyond its humble beginnings. Today’s Eurorack user is faced with an almost limitless amount of options and an unprecedented amount of complexity and function density, which can quickly become overwhelming and paralyze the music-making process for both beginners and more experienced users.

In light of this, the new Doepfer Basic System is both a return to Dieter Doepfer’s original vision of analog modular synthesis and an attempt to build a coherent and approachable modular synthesizer system that can live up to the demands of contemporary music education – with the trust and confidence of Eurorack’s oldest brand. As such, it is intended for both beginners and all those that want to explore fundamental concepts of analog modular synthesis with a renewed focus.

The Basic System is basic in two senses. First, it presents a return to the most basic building blocks of analog synthesis with simple, knob-per-function interfaces and layouts. Secondly, it presents a reliable base on which someone can build their further foray into modular synthesis, and electronic music-making in general. However, this design philosophy centered around the idea of the basic does not mean that the system is stuck in the past. It carries with it all of the advances in circuit, module and system design that have been made within the last decade here at Doepfer. Compared to its predecessors, this new system is sleeker and more approachable, but also more flexible and powerful.

Aside from just offering an all-around better system, we also wanted to use this revision as an opportunity to rethink what a Basic System can mean, and do, for today’s electronic music education. With its design and configuration, we think it is an ideal system to teach anyone the basics of analog electronic sound synthesis. As such, we took special care to produce documentation that is not just technically adequate, but also musically educative and inspiring. The result is the book you are holding in your hands right now. It is something unique, serving as both a complete manual and a hands-on “patch book” full of carefully illustrated and documented patching ideas to get you inspired and started making sounds and music. The patches in this book cover many of the most commonly used types of synthesizer sounds. They also were designed to be immediately playable and musically useful, quickly taking the modular synthesizer from theory into practice. Just record and arrange a few different patches and you might already have a full song! We also think this is the best (and most fun!) way to learn, quickly taking you from the simple patches in the beginning of the book to more complex patches later on.

As is common with analog modular synthesizers, this system has no digital pre-set patch storage, meaning that every new patch is also a new beginning. While this limitation can seem intimidating at first, many users quickly learn to love the sense of exploration and freedom this provides. When building and re-building patches manually, using your hands, eyes, and ears, they will always come out just slightly different – and that’s fine and part of the fun! In order to make the patching process as fluid and enjoyable as possible, Doepfer modules (unlike many contemporary Eurorack modules) prioritize immediacy and playability in their design, with simple knob-per-function layouts, clear labeling and logical arrangements and enough space to get your hands in there and start moving and shaking things!

While much effort and care has gone into designing and configuring the best possible self-contained system, it should be noted that the Basic System is still emphatically modular. If you (for some reason or the other!) do not like or vibe with a certain module, you could remove it and replace it with any Eurorack-compliant module that fits, both from Doepfer and other manufacturers. And all of the modules in this system can be patched together with modules from any other Eurorack system. The Basic System is a fully configured, ready-to-use system, but an open system that can be expanded and reconfigured as you wish. To emphasize this modular nature, the system also comes with some open space you can fill as you wish.

Although our patches present you with various usage suggestions, you can easily alter them to your liking, or even do something else entirely. The system itself presents no inherent hierarchies or structures that you are forced to follow. For example, in most of our patches, the oscillator sound-sources are set up for equal temperament keyboard pitch tracking for immediate playing and sequencing. But if you were feeling a little experimental, you could easily alter the patch and tune them to a micro-tonally instead. We greatly encourage such exploration, which is why every patch comes with a “make the patch your own” section with ideas on how you could explore the patch and take it further to make it your own.

Even if you have played with traditional, fixed-architecture synthesizers before, the sense of exploration and possibility that the Basic System presents will make you see electronic sound synthesis in a new light. When made freely patchable and modulateable, the basic building blocks of synthesis become much more than the mere sum of their parts. With the power of free patching at your fingertips, you can construct both a workhorse synthesizer voice and an insane experimental twittering-machine – the choice is up to you!

The act of patching a hardware modular synthesizer is often compared to the experience of playing with LEGO as a child, a comparison that we would like to embrace. In our day-to-day lives, we all play too little. The Basic System is both a playground for creativity and an interactive, dynamic instrument that opens up a unique dialogue with each user, inviting them to explore and play more, always opening up new combinations and possibilities along the way. In modular synthesis, the unexpected will happen, but there are no mistakes or wrong patches, only happy accidents and opportunities to learn and create. We hope that this system may bring you joy.

Machina Bristronica – this Saturday!

If you are based in the UK or happen to be there this Saturday, the Machina Bristronica event is a great place to spend the day! Many many brands such as AJH Synth, Endorphin.es, Doepfer, Eowave, Neuzeit Instruments, Between Machines, Vermona, Haken Audio, UDO Audio and Buchla USA will be exhibiting there! There will be DIY workshops concerts and talks. Frap Tools will also be hosting an educational workshop.

Around the main exhibition hall you’ll find all kinds of (modular) synthesizers, software, modular makers, drum machines, case builders and effects units from many well established instrument makers alongside plenty of unique and unusual independent designers.

In the concert room you’ll get to see great performances by no other than Julia Bondar, JacqNoise, Scanner, Dopplereffekt and many more – from 11:30 to 22:00.

Sounds like a fun day for any synth enthusiast!

Check out the website for more info.

The first DOEPFER modules announced at SUPERBOOTH23 are available!

Three of the four modules announced by DOEPFER at SUPERBOOTH23 are now available!

A-101-8 Photo Phasing

The A-101-8 Photo Phasing is not only a nice idea to fill gaps in your system, but also a full-fledged phaser – inspired by the Schulte Compact Phasing A (aka “The Krautrockphaser”). The module is a promising candidate for a classy analog effects module (especially when you only have 4hp left). Phasing can make any boring sound interesting and deeper. We are looking forward to testing it out!

A-147-4 Dual LFO

The next new module that just arrived is the A-147-4 Dual LFO. A fully featured analog LFO module that can be a real workhorse in any system. And it tracks 1V/oct (up to about 2500Hz) as long as the attenuator for the CV is fully turned up. So with the Doepfer A-147-4 you also have a handy dual (utility) VCO in your rack. Well done DOEPFER!

A-171-4 Quad VC Slew Limiter

The third new module A-171-4 Quad VC Slew Limiter is part of the DOEPFER poly system. It features four slew limiter circuits with one set of controls – perfect for adding more expressiveness to your poly setup! But of course you don’t necessarily have to use the module as part of a Doepfer poly setup.

A-135-5 Polyphonic Mixer

The fourth module (A-135-5 Polyphonic Mixer), which Doepfer announced at SUPERBOOTH23, has not yet arrived because Dieter wanted to add an additional feature that some customers suggested to him. The mixer will get mute switches and we are looking forward to an even more useful module when it is ready.

Here is a nice video by Sonicstate.com with Dieter Doefer and Holger Zapf explaning the new designs!

Kekse backen with Dieter Doepfer at SchneidersLaden

Ever wondered how your modules taste? Whether a VCO feeds longer than a filter, for example? This big, important question might be answered on December 6th! Dieter Doepfer is coming to SchneidersLaden to bake some cookies with you! For the last workshop night of this year we prepared this very special evening for you – join us and not only get a free cookie, but also learn more about recent developments by Doepfer.

As a special treat Dieter Doepfer will be doing the Modular Beginner Workshop! Your chance to be guided into Eurorackland by the person that started this format for modular synthesizers. And because Dieter Doepfer is a great guy, you will get a cookie (or two) – fresh out of the oven – that were baked at SchneidersLaden!

December 6th – starting at 6pm -> join our Modular Synthesizer Beginner Workshops!

Cookies and talk at about 7:30pm!


The workshop is limited to 20 persons, so…
>>>     Please write Timm for confirmation: Participation is free-of-charge as always!


How to find us:

DigitalAnalog 2018 is over – It has been very nice being able to take part in this unusual festival held in Munich’s iconic Gasteig. Sad to say the city’s council will tear down this location in order to make space for something new and posh to battle Hamburgs new opera house. But before that is going to happen we will definitely join the following edition of DigitalAnalog in 2019 with an even bigger modular playground and surely perform live as well. The interest in modular instruments and our Karusell was very high again and we are glad to report that the number of female players seems to increase significantly. So we are looking forward to going south again next year! Many thanks to all involved and to all employees of Gasteig, who made a very comfortable stay possible for us!

What about… some modern classics?

Oldie but Goldie? There are certainly some modules that drifted out of focus, especially to new users of modular synthesizers. Today we will be retrospecting on modules that have been around for a long time and are still available. Looking back at the beginning of the eurorack format,  it was quite easy to keep track of new developments – there was Doepfer from Germany and there was Analogue Systems from the UK. Both are still around and offer most of the modules they produced until today. And now it is even possible to put AS modules into a Doepfer System (the now “standard” eurorack) without buying an extra adapter, because AS modules are now available with compatible bus connectors – the Dual-Bus.

Analogue Systems

There is the great sounding RS95e – a VCO that is always a good choice for thick vintage sound, an excellent choice for an oscillator with lots of character. Other often recommended modules by AS are: The Analogue Systems RS-510e which is based on the legendary EMS Trapezoid Generator and the excellent sounding RS-110 Multimode Filter – both great analog designs with a special twist! The RS-110 for example offers an open feedback-loop! The socket Res-Out and Res-In act like an insert i.e. they allow you to process the audio signal in the feedback loop by other audio processors like filters, distortions, delays, frequency shifters etc.


Doepfer also offers great filters, often very affordable compared to competitors and always real workhorses. For example the A-124 Wasp and A-106-5 SEM filter are not only two of the cheapest filters available, but also great sounding choices. They are based on vintage designs (obviously) and really do a lot of things right – these will most likely never leave your rack again, they are great sounding multimode-filters, cheap and small, while not being too fiddly. The Wasp is a great dirty and unstable design that gives your sound a lot of liveliness and power. The SEM is a smooth sounding and vibrant filter that works great (not only) for basslines.


And there are more manufacturers that have been around for a while – for example WMD. Ever heard of the micro-Hadron-Collider, Synchrodyne or Geiger Counter – great names and great modules! All by WMD. These three modules have been available for several years now and all offer something special. What sets the uHC – a dual state-variable-filter – apart from most other VCFs is the integrated voltage controlled mixer. It can be used to create different and new filter modes – Wide Notch, Dual Bandpass, etc. It is also great for blending separate sounds together using both filters split and it allows cool frequency modulation of the mixed signals. The Synchrodyne is very interesting due to a combination of building blocks, which no other manufacturer packed together into one module. It contains most parts of a traditional synth-voice, but it goes a much different way. There is an analog sawtooth wave oscillator with a waveshaper, a “switched capacitor” filter and a PLL circuit which drives the cutoff frequency of the filter. HERE is a video of one (of many) possible uses of the Syncrodyne, this is so unusual that I had to add it. The WMD Geiger Counter is… another thing of its own…I wanted to say, but then there are about 5(?) different incarnations of this bit-crusher design! Only one of them is a eurorack module though. What they all share is a modern high gain preamp that drives an 8 bit computer, creating sounds which range from nice to unbelievably alien. Give. It. A. Try.

Lots of normalizations and patch-points are typical for WMD modules, resulting in very complex, powerful and – in the end – rewarding designs. There are of cause more manufacturers and modules that deserve to be in this post, but let’s keep some for next time.


This is by no means a complete overview of the available modules or a full review of the modules discussed. The What about… texts are here to give you new ideas and maybe another perspective on things. All these modules offer more features than we have talked about in this post. For further information please click the provided links or – even better – visit the shop and ask the SchneidersLaden experts in the showroom.



At Superbooth 2018, Dieter Doepfer introduced new “quad” modules made for polyphonic use.


The A-190-5 is a new polyphonic MIDI/USB-CV/Gate interface. For each voice a pitch control voltage (1V/octave standard to control VCOs), a gate output (to control envelope generators) and two additional control voltages (CV2, CV3) are available. The two additional CV outputs can be controlled by Midi velocity, volume, modulation, pitch bend, after touch or free assignable Midi controllers.


A-111-4 Quad VCO contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master unit for all four VCOs.

A-105-4 is Doepfer’s first polyphonic filter and contains four identical 24dB Lowpass filters (SSM2044 type). It has available common manual controls and CV inputs with attenuators for these parameters.

A-132-8 is an octal VCA and primarily planned for polyphonic applications. The module contains four VCA pairs. Each pair includes two daisy-chained VCAs. One VCA has a linear control scale, for the second VCA linear or exponential control scale can be chosen by means of jumpers. We decided to provide two VCAs for each voice because usually one VCA is required for loudness envelope and a second one for velocity (or other functions like individual voltage-controlled loudness of each voice, amplitude modulation and so on).

A-141-4 is a quad voltage controlled Envelope generator and is primarily planned for polyphonic applications. The module contains four ADSR type voltage controlled envelope generators with common manual controls and CV inputs with polarizers for the all parameters Attack (A), Decay (D), Sustain (S) and Release (R). Each of the four envelope generators has available a gate input, a control LED and an envelope output.

Doepfer also introduced a few other modules with interesting features.

A-123-2 is a voltage controlled highpass filter with four filter outputs (6, 12, 18 and 24dB slope). It also features voltage control of the resonance.

Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.Module A-142-2 contains two envelope controlled VCAs behind a front panel with 8 HP only. Each of the two sub-units is the combination of a simple AD/ADSR/AR envelope generator and a VCA. The type of envelope can be selected by means of a toggle switch.

A-157-4 is an expansion for the A-157 Trigger Sequencer and adds a MIDI/USB/Control-Outputs Option.

GusGus (+special guest) live concert @SUPERBOOTH18

GusGus at SUPERBOOTH18 – what a special night and special guest! As the final headliner on the last day of SUPERBOOTH18 GusGus played in the K1 and it was a perfect last act for a successful third year of Superbooth! The packed room not only saw a great performance by GusGus, but also witnessed Dieter Döpfer joining the stage and playing together with Birgir „Biggi Veira“ Þórarinsson on the mostly Doepfer equipment. These special situations make Superbooth an outstanding event in the annual program of electronic music events, it is about community, making music and sharing a passion. Enjoy this video!


NAMM 2018 – Doepfer (Modular)

Doepfer goes polyphonic! – After releasing the A-111-4 Quad VCO a couple of months ago, Dieter Doepfer now presents four-voice filter, VCA and envelope modules. By combining the circuits, you can set up a full-blown polyphonic synthesizer within your Eurorack setup. While the A-111-4 has separate knobs and switches for each of its oscillators, the voices of the new modules share a set of control elements. Therefore, it is very easy to produce even results.

The A-105-4 Quad SSM VCF is a four-voice low-pass filter with an edge steepness of -24 dB per octave. As the name suggests, the module is based on the SSM 2044. – The same chip that was used in vintage instruments like Korg’s Polysix and Mono/Poly, the Fairlight II, several PPG synthesizers, early Prophets and EMU’s SP1200 sampler. The A-105-4’s sound character is thus classic and powerful. High resonance settings make the circuit self-oscillate. The module’s input level is adjustable. Hot signals result in beefy distortion. Besides an audio input and output, there is a FM socket (plus global attenuator) per voice. – Perfect for connecting envelopes. Furthermore, the A-105-4 features several CV inputs which influence all voices conjointly. In detail, cutoff and resonance as well as the audio and FM level can be modulated with the help of these connectors. Attenuators are present here as well.

Doepfer 01_s

The A-132-8 contains two daisy-chained VCAs per voice. One amplifier circuit features a linear control scale and is thus tailored to be controlled by an envelope. The other VCA can work with either linear or exponential characteristic. It is primarily meant for adding velocity sensitivity to polyphonic patches, but can be used for other purposes as well, of course. Both VCAs are equipped with a potentiometer for adjusting their initial gain. Thanks to a sum output, the A-132-8 can serve as a mixer in monophonic patches.

The A-141-4 Quad VCADSR combines, as the name suggests, four envelopes in one module. All phases (attack, decay, sustain and release) are voltage controllable. The corresponding CV inputs are equipped with bipolar attenuators.

Doepfer 03_s

For playing polyphonic patches, Dieter Doepfer designed the A-190-5 MIDI / CV interface. It features four channels with CV note, gate and two additional control voltage outputs each. Thanks to DIN and USB ports, the module can be connected to hardware sequencers and controllers as well as a computer. Besides polyphonic modes of operation, there are duophonic, paraphonic and monophonic modes as well.

Doepfer 02_s

Besides the polyphonic modules, Dieter Doepfer presents some classic mono circuits at the NAMM show 2018 as well. First of all, there is the A-123-2 high-pass filter. It features four outputs emitting signals processed with an edge steepness of -6 dB, -12 dB, -18 dB and -24 dB per octave. The A-140-2 is a very compact dual ADSR module. Via CV inputs, you can modulate one or more envelope phases. Last but not least, there is the A-142-3, a combination of an AD / AR envelope and a VCA which is only 4 HP wide.


Here is a video by sonicstate:

NAMM 18 – Doepfer Dark Energy III

Doepfer introduced their version of the Dark Energy semi-modular Desktopsynthesizer – Dark Energy III.

The main differences between Version  II and III are an improved VCO (no warm-up period, additional triangle waveform, wider frequency range), resettable LFOs, improved ADSR and a lot of internal access points for DIYers. The favored filter of the Dark Energy II has been unchanged. Dark Energy III is a monophonic stand-alone synthesizer with USB and Midi interface. The sound generation and all modulation sources are  still 100% analog, only the USB/Midi interface contains digital components.

The Unit should be released in a couple of weeks – the spring will be darker – oh yeah.

What about … filterbanks?

Shaping sounds is something to get lost in. Turning knobs on a new module for hours, without noticing how time flies by is something most synthesists have experienced before. The number of options to shape a sound are almost unlimited. Here we are looking at one obvious way to sculpt sound – filtering.

When you take the concept of a filter and implement it several times into one module it results in something that is called filterbank. This type of circuit consists of a number of filters most times sharing one input and one output. The input signal passes the filters that are wired in parallel, this is why filterbanks are perfect tools for precise work on the frequency spectrum of a sound. Each filter usually has a fixed frequency that can be cut or boosted, either voltage controllable or not.

It is not easy to define fixed cornerstones for filter banks, because the available options are so different in their functionality. Therefor we have a look at some of the concepts that are on the market today, covering a price range from ‘yeah I didn’t plan to get one, but I’ll give it a try’ to ‘uff, maybe one day’.

Filterbank klein

Doepfer A-128 Fixed Filterbank

The Doepfer Fixed Filterbank might be the most basic implementation of a filterbank. One input, one output, fixed frequencies and no voltage control. It won’t break your bank, is pretty hands-on and will definitely bring something new to your sonic repertoire. With 15 fixed filters, one low-pass at 50 Hz, one highpass at 11kHz and 13 bandpass filters in-between, there is a lot of potential for precise sound design. The Doepfer excels in feedback loops for example. Using it in the feedback loop of a spring reverb or delay is a great way of controlling and shaping the character of these effects. Or use it with your noise sources, or literally any other sound source to cut unpleasant frequencies and leave room for others.

ADDAC 601 VC Filterbank

The ADDAC filterbank is a lot more complex than the Doepfer, but features “only” eight filters bands. Each band features voltage control of its amplitude and a separate envelope follower, which lets you extract voltage control signals from your audio input – a very handy feature. There are two audio inputs but a total of 12 audio outputs – one for each band (post a VCA), one for the even, one for odd frequency bands and an output each for the dry and wet signal. The ADDAC Filterbank is a very versatile machine to sculpt any audio material and additionally to extract control voltage to either spread across your system or modulate the filterbank itself. Cross-patching the envelope follower outputs to the amplitude CV inputs should be fun, as well as feeding the even/odd outputs back to the second audio input.

Verbos Electronics – Bark Filter Processor

Even more sophisticated is the Verbos Bark Filter Processor. It basically features everything the ADDAC offers plus a bit more – first of all those nice faders that some other Verbos modules feature as well. This special filterbank is based on the Bark scale, a psychoacoustic perceptual scale of pitches with 24 ranges of frequencies. The module’s twelve frequency bands represent roughly ‘every second band’ from the Bark Scale: <100Hz, 300Hz, 510Hz, 770Hz, 1.08kHz, 1.48kHz, 2kHz, 2.7kHz, 3.7kHz, 5.3kHz, 7.7kHz and >10,5 kHz. The 24 frequency ranges in the Bark scale are graded in 24 Barks and doubling of the Bark value means that the corresponding tone is perceived to be twice as high.

Each filterband of the Bark Filter Processor corresponds to one of the faders, the levels of the filter bands can be set and modulated in a number of ways – manually with the fader and/or with a CV which is injected into the socket below the fader. On the other hand there is the scan function which dynamically controls several bands, independent of the faders: “Frequency Scan” sequentially scans through the frequency spectrum, with Center and Width determining the center frequency and bandwidth; “Spectral Tilt” either emphasizes the low or high harmonics. Especially these functions, the look and feel and the special selection of frequency bands set the Verbos Bark Filter Processor apart from other Filterbanks.

Sherman Filterbank 2 – classic version

This is not a eurorack module, but something that can give you a similar experience with lots of in and outputs are available to interact with your other machines.

An absolute classic – available for about twenty years and still able to gain more interest. The different versions of this machine cover all kinds of applications; there are rack-mounted versions for mono or stereo, tabletop models and the latest edition – the Sherman Filterbank 2 Compact.

The Sherman has a different structure than the eurorack filterbanks described above. While only featuring two (multimode) filters it also offers envelopes, noise, FM input for external audio – LFO or other CVs, VCA overdrive with additional AR envelope generator and a ring mod input. This is a lot to play with. The combination of the different sections remind a bit of resonators or even whole synth voices, only without VCOs. But with the two multimode filters with adjustable cutoff frequency and resonance, overdrive capabilities and playability, this is a really interesting tool for shaping sounds. And the Sherman Filterbank is an instrument in itself, by using it without an input there is a noise source active that you can run through the rest of the circuit. This piece of hardware really is a tool that wants your attention, but it pays back with massive audio adventures.

What about… classic and less classic analog VCOs

A square wave is a square wave and a sine a sine – right? Yes … but on the other hand – no, not quite. Even with classic analog VCOs, that output classic waveforms like saw, square, triangle and sine there can be significant differences in their circuits, structure and sound. And as VCOs usually are the basis for your sound it might be worth to think a bit about what a VCO can do for you and what character your VCOs should have. Writing about the different sound of VCOs is a bit difficult as it is a pretty subjective topic. Anyways here are some thoughts about analog VCOs that all have something special and add a nice trick or two to your rack.

VCOs lang

Classic Sound

The first two examples are special because of their history, quality and big vintage sound. The AJH MiniMod VCO is what you could call a real classic VCO, no fancy functions just good sound and solid engineering. And this is what makes this VCO so special. As it is designed after an earliest revision (Mk1) of the famous Minimoog the sound of these VCOs is classic, big and beautiful. The tracking has been improved and the built quality is excellent. What you get is the sound of the Minimoog, even with the special “sharktooth” wave, that was unique to this synthesizer and is now available in eurorack. The NTO is the most advanced VCO ever designed by Serge and the Random*Source – Serge New Timbral Oscillator (NTO) is an adaption for eurorack that has been developed in close cooperation with Serge. It features all the basics you would expect from a classic VCO and this it is – a VCO that has the word vintage written all over its sound. And with the NTO you buy a part of synth history, as the original design was first implemented in the famous TONTO synth that Stevie Wonder was using in the early 1970ies. The TONTO has been the most advanced polyphonic (modular) synthesizer that existed worldwide for a long time and the NTO was the most advanced VCO. The Random*Source version features excellent tracking and an output for the voltage controlled waveform.


Frequency Modulation

The Liivatera – Through-Zero VCO has its specialty already in its name. The Through-Zero term is related to a special behavior wenn frequency modulating the VCO. In a nutshell – it sounds better. The FM sounds are brighter and usually more pleasant to the ear. The technical side of things is a bit more complicated than in the usual FM circuitries and therefore not often implemented in VCOs. But the Liivatera VCO has another trick up its sleeves – the reversing sync input is something not to be found on many VCOs. The syncing behavior is switchable between rising, falling and rising & falling edges of a signal – plus: the trigger threshold is voltage controllable. With these options you get a lot of variety in sync-sounds. The Liivatera VCO is a very nicely engineered VCO for an excellent price point if you consider its functionality and quality. The through-zero technology you get with the Liivatera can also be found in the even more advanced Rubicon by Intellijel or the simpler Doepfer A-110-4.

The next VCO to be discussed is a unique design. The Berlin based artist and designer of electronic musical instruments Christian Günther has developed a special analog VCO with two sperate 1v/oct inputs that can be selected at audio rates – the CG Products – XR22 VCO (Finetune). This opens up new sonic territories as the two frequency control circuits can be switched and controlled in different ways. This adds a very wide range possibilities to an otherwise standard oscillator – this is a way more complex module than it appears. The description of the circuit seams to be easy to understand, but the complexity of the sound that comes out of this module is huge and demands some time to learn and experiment – but its worth it.


Different sizes

The next VCO is a future classic by Doepfer. The Doepfer A-111-4 Quad Precision VCO. The A-111-4 is a very interesting addition to the wide Doepfer range of products. What makes this one special is that its compiled of four individual precision VCOs and a mixing stage. This module is the perfect starting point for polyphonic setups or really massive analog mono voices. With the size of one more advanced VCO the A-111-4 maybe the most analog VCO per hp in eurorackland. With the mixing stage this VCO makes a great starting point for massive mono voices that only go through one filter/VCA … or tune the four VCOs to form a chord … or play a massive drone … a lot of interesting things can be done with four VCOs in such a small space!

The next VCO maybe the complete opposite of the Doepfer. It is huge. The Harmonic Oscillator by Verbos Electronics is as big as it gets when you look at single Oscillators. When you go through the features of the Harmonic Oscillator, and start on the left side – everything appears very common and “normal”. Different waveform outputs, tuning knobs, CV inputs. But right next to these basic features the interesting part of the Verbos VCO begins. The fader control the first eight harmonics of the fundamental tone – each with its own output, the level of which is controlled by the corresponding fader. Directly below the faders there are two sections for playing with the eight harmonic channels and their sum output. The first one scans through the harmonics from low to high or from high to low, by setting the width you can control the overall effect of this feature in an very intuitive way. Next to this function there is the spectral tilt section which lets you emphasize the low or high harmonics. The Harmonic Oscillator gives you a very interesting package of standard functions and functionality and playability that you won’t find elsewhere.


To create sound in a modular environment isn’t hard. Take an LFO, envelope or function generator, like a Befaco Rampage or Make Noise Maths and loop it fast enough – like this you get an audio oscillator and there are tons of other ways. But to have a dedicated module for this gives you more flexibility for frequency modulation, sync options, different waveform outputs and all the other little bits described above. Through-zero modulation, harmonic overtones, or a dual frequency modulation circuit – these are only some of the available options you will find in eurorack VCOs these days. And if you are searching for that special vintage and all-time classic sound, you are also able to find this in modern VCOs with classic and classy sound.

This is by no means a complete overview of the available modules or a full review of the modules discussed. The what about… texts are here to give you new ideas and maybe another perspective on things. All these modules offer more features than we have talked about in this post. For further information please click the provided links or – even better – visit the shop and ask the SchneidersLaden experts in the showroom.

What about…Voice-Modules for eurorack


It is one of the best things about modular synthesizers – you can mix and match all elements of your instrument. Your dream is to combine a wavetable oscillator with a classic Moog-design filter and a tube-VCA? – No problem, go for it! But sometimes all you want is another simple analog subtractive voice. Or maybe you have something like 30hp of space left in your case, so why not throw a complete analog mono synthesizer in there? And often these modules are the perfect entry point for the mysterious land of modular synthesis, not only because you have everything on hand that you need to start making music – but also you can be sure that the single components work well together. With single modules you sometimes happen to combine modules that are not the perfect companions as a filter might expect 10V to fully open the cutoff, but your envelope only produces 8V…and so on. So with full voice-modules you can prevent some of the typical modular synth trouble shooting. Therefor a synth-voice module is often a good starting point for beginners and an easy and pleasing thing for experts to add another voice to their system. Just add a sequencer of your taste to the module and you are good to go! Here are some thoughts on typical analog mono-synths in eurorack format.


Acidlab – M303

Sometimes all you need is a bass synthesizer – and the most famous one might the Roland TB-303. So why not put something like a TB-303 in your rack? This is where the Acidlab M303 comes into play. A good sounding, affordable all in one bass synthesizer that reminds of a TB-303 sound wise. All you need to do is add a sequencer and you’re good to go – ACID! And the M303 offers a lot more flexibility than a standalone version. With inputs for its filter and VCA you are able to process totally different sound sources than the original saw- and sqaurewave, if you want to.


Eowave – Domino (Module)

This miniature synthesizer is also often referred to as a kind of 303 inspired synth. But is has more of its own sound, a pure analog, rough and strong sound that can go into 303 territories but is way more flexible…with 12 patch points, when it comes to integrating it into more complex patches. And have you seen the size of it?  – To have a full analog mono synthesizer in ->10hp<- ! is kind of ridiculous – in a good way. It features saw- and square waves just like the M303 but lets you blend between the two and the filter is different as it is a -24db ladder design.


MFB – Nanozwerg Pro

This little analog synthesizer features a sub-oscillator and noise circuit that the M303 and Domino are missing. It also features a multimode filter and additionally two ADSRs and an LFO – and it is the cheapest in this series. This is a challenge that MFB has mastered many times before – building incredibly affordable instruments with lots of functionality. And often they are surprisingly good sounding, as the Nanozwerg Pro proves. It makes no compromises: Noise, Sub, LP- BP- HP- Notch-Filter, Saw, Square, Triangle and Pulse waveforms, 2 x ADSRs, LFO, octave switch AND MIDI-input! You are missing something? Well, good news is: you will have saved a lot of money by buying the Nanozwerg Pro, so there will be something left for whatever you feel is missing.


Intellijel Designs – Atlantis

The most sophisticated of the modules we are discussing here is the Atlantis by Intellijel. With 27 patch points, noise and a loopable envelope this is not only the best equipped of the four modules discussed here but also the most flexible. The Atlantis comes close to a synth voice that is built from separate modules when it comes to the feature list and patch points. Additionally pretty much any function of the Atlantis can be used independently, which contributes to the feel of using separate modules when working with the Atlantis. And what about the sound? The architecture of this module is inspired by the SH-101. And it sounds close in particular settings. The Atlantis is a great mono-synth and can sound huge.


Doepfer – A-111-5v Synthesizer

Only 100 units will be available of the module A-111-5v Mini Synthesizer Voice. This special edition is only possible since Dieter Doepfer found 100 of the special-IC CEM3394. This module features a VCO, a 24dB-Lowpass filter, a VCA, an ADSR-envelope generator and two LFOs. The special thing about this module is its linear filter FM. The A-111-5v can be seen as the eurorack version of the Dark Energy MK I! And it features the CEM-chip that is responsible for the powerful and pleasant sound of the original Dark Energy. Now Doepfer is doing a limited run of A-111-5 Synthesizer Voices with this legendary chip.

In the end it is a matter of taste whether you rate one above the other, at least most of the time. When only having a few hp left in your live rig the Domino or M303 might be a good choice. On the other hand you might have ended up with a rack full of digital modules that you want to complement it with a more veratile analog voice, then the Intellijel or Doepfer might be the right module for you. Whatever your considerations are, this article has hopefully given you some insights in a few of the available options.

This is by no means a complete overview of the available modules or a full review of the modules discussed. The what about… texts are here to give you new ideas and maybe another perspective on things. All these modules offer more features than we have talked about in this post.

What about… CV processing?

Using and working with control voltage (CV) in your modular synthesizer is essential, but often people tend to focus more on audio signals and audio effects. However there is a lot that can be done with CV signals to widen the potential of your modular synthesizer. Here, we are talking about some utility modules for processing CV signals. Some are offering more basic functions, but with a nice twist, like the Livestock Electronics Felix and Doepfer Precision Adder. Others are feature packed CV-super-tools or bring new ways of mangling CV in eurorack to the table.

Doepfer A-185-2 Precision Adder / Bus Access

Having more than one voice playing in your system you might want to transpose them together, or you want to combine two or more sequences. This is where the Doepfer A-185-2 Precision Adder comes in handy. with its four in- and outputs it can be used as a tool to tie your different sequencers together or work as a simple octave switch for your oscillators. A simple but effective module with a wide range of functionality, especially when handling pitch CV.

Livestock Electronics – Felix

Felix can be used as buffered multiple and/or signal distributor. At the price of other simple buffered multiples it covers way more ground than these. Each output features an attenuator / attenuverter, emitting signals in the range of either 0 V to +5 V or -5 V to +5 V. The level of signals can be adjusted via potentiometers. As long as you don’t plug-in a cable at the left input, the outputs generate voltages in the range of 0 V to +5 V (attenuator mode) respectively -5 V to +5 V (attenuverter mode).

Rabid Elephant – Knobs

The Knobs by Rabid Elephant is one of those CV-super-tools. It is built with only the best parts available and rock solid, but what makes it really special is its playability.  This ultra-precise dual CV processor (with attenuversion, offset and slew) and voltage controllable crossfader is a perfect tool for playing control voltages like a DJ – a thing you might have never thought of yourself. It is a quality module, it is lots of fun to play with and opens new perspectives. The crossfader is a nice addition to a CV processor that can change to way you look at things. A “boring” CV can become an exciting thing to play with.

4ms Shifting Inverting Signal Mingler (SISM)

The SISM is one of three modules with that “4-channel-layout” by 4ms. In fact it features a header for connecting a Quad Clock Divider, Quad Pingable LFO or the VCA Matrix by 4ms. But what does it do in the first place? The SISM is a CV processor with four channels of attenuation, attenuverting and offsetting incoming CV. For this purpose it is equipped with four in- and outputs. Additionally there are outputs for the mix of all positive or all negative voltages, a mix of channels where no cable is inserted into the output socket and a mix that represents the direct sum of all four channels. So you get three additional CV sources that are related to your inputs – very useful.

Doepfer A-152 Voltage addressed S&H / Switch

The A-152 is a bi-directional switch with either eight inputs and one output or vice versa. This way you can send up to eight different signals from different sources to one destination or one signal to up to eight destinations, eihter by switching via gate, one stage after the other, or address the different stages via CV. While doing this the A-152 derives additional information from what you are processing, e.g. it gives out a gate at the stage that is active at the moment and it holds the last value a stage had as long as it was active. See?  –  This module lets you work very creatively with your CV’s and it even derives additional Gates and voltage sources from what you are feeding the module.


All in all there a way more modules and options out there to process CV in eurorack. This is just a brief overview of some of the creative concepts module designers have come up with in the last years.

This is by no means a complete overview of the available modules or a full review of the modules discussed. The what about… texts are here to give you new ideas and maybe another perspective on things. All these modules offer more features than we have talked about in this post.

What about… low-pass gates?

[et_pb_section fb_built=”1″ admin_label=”section” _builder_version=”3.0.47″][et_pb_row admin_label=”row” _builder_version=”3.0.47″ background_size=”initial” background_position=”top_left” background_repeat=”repeat”][et_pb_column type=”4_4″ _builder_version=”3.0.47″ parallax=”off” parallax_method=”on”][et_pb_text admin_label=”Text” _builder_version=”3.0.47″ background_size=”initial” background_position=”top_left” background_repeat=”repeat”]

The low-pass-gate is a traditional Buchla design that has some mysterious qualities to it. For decades it has mostly been seen in Buchla synthesizers and luckily is now available in various forms, formats and styles. But what is a low-pass-gate? It is an electrical circuit that combines elements of amplifiers and low-pass filters. Therefor it will be used to determine the amplitude of a sound and its sonic complexity.

Due to its technical structure it is possible to just send trigger to the CV inputs of low-pass gates and still get envelope-shaped results. This is because low-pass gates usually use vactrols –  photoresistive opto-isolators, or or opto-couplers. What is that? Basically vactrols are light-emitting diodes (LED) or another light-emitting component and a semiconductor-based photoresistor. With these two components you have a source of light and a detector of light, both sitting in a closed housing, electrically isolated from each other. When you send a voltage into a vactrol – the light-emitting part – will emit light and the detector will receive this light = this opens the gate. And because this special construction is some kind of slow, it has a special natural sound to it. And as the light received by the detector is opening the VCA and controlling the filter cutoff at the same time sounds   at low amplitude will sound duller. And this is where the magic happens, this behavior in combination with the “natural” respond of vactrols make low-pass gates sound so nice.

LPG_what about banner

Make Noise – Optomix (Rev.2)

All time classic: The Optomix is might be THE module people think of first when talking about low-pass gates in eurorack. It has been around for years and has built a large fan base. The Optomix by Make Noise actually features two low-pass-gates utilizing 4 vactrols to provide simultaneous voltage control over amplitude and frequency content of a signal. In Rev. 2 the damp circuit was updated to accept audio as well as CV for patching side-chain compression. Additionally Optomix offers a summing stage complete with an AUXiliary IN allowing for the chaining of multiple units to create larger mixes.

Rabid Elephant – Natural Gate

The Natural Gate might be the most advanced low-pass gate when it comes to engineering complexity. Due to this it has some unique features exceptional sound design capabilities. For example, it is possible to choose between three “material characteristics”, each of them responding differently to excitation signals. As the trigger frequency increases, the low-pass gates open up more and more. Additionally the decay varies depending on the pitch of incoming audio material. Thanks to this behavior Natural Gate has a very pleasant sound and a very natural sound. Its two channels also featuring ducking compressor, wave shaper or envelope functionality.

Doepfer A-101-2 Vactrol Lowpass Gate

The Doepfer A-101-2 Vactrol Lowpass Gate is a single low-pass gate with the ability to also be used as VCA or low-pass filter – and it features resonance control that not many low-pass gates provide. It has a rather aggressive sound, especially with lots of resonance. What also sets the Doepfer apart from others is that you can set the mode of operation not only manually but also via gates, which is the reason for two gate inputs; this is very interesting in combination with clock dividers or trigger sequencers.

  • Gate 1 high & gate 2 low = low pass mode
  • Gate 1 low & gate 2 high = VCA mode
  • both Gate 1 & 2 high = combo mode

Metasonix RK5 Dual Low Pass Gate

The Metasonix RK5 Dual Low Pass Gate is a very special module. It takes the concept of a low-pass gate, invented in the 1970s and uses technical solutions from the 1950s – vacuum tube audio circuits. The module offers a very special warm and gently distorted sound with a rather long decay. It is the perfect module for those who want to explore “new” low-pass gate timbres and want to create unique, somewhat dirty Buchla Bongos and other percussive sounds.

Verbos Electronics – Amplitude & Tone Controller

The Verbos Amplitude & Tone Conroller consist of a entirely discrete VCA combined with a vactrol controlled low-pass filter. The input stage lets you dial in a very pleasant distortion if you want it to. The sound is gorgeous somewhere between wood and acid. As all Verbos modules this is a very high quality module with a classy vintage sound. And you don’t only get the sound but also the look – how beautiful it is!

Make Noise – DynaMix

The DynaMix is the second Make Noise module in this overview, as Make Noise is constantly developing new modules featuring vactrols and keep exploring what low-pass gates can be. It is also as a two-channel low-pass gate with integrated mixer. Instead of vactrols, transistor circuits are used to control the integrated filters and VCAs. This results in a harsher and faster responds than with an integrated vactrol. Its sound is comparatively hard, but nonetheless very musical and the circuit is capable to gently distort the sound when you want it.

Gammons MODULAR SYNTHESIZER ENSEMBLE is on tour during November 2017. The concept for these workshops is to create a Modular Synthesizer Ensemble with the participants and to be able to play an improvised concert in the end. The Modular Synthesizer Ensemple is supported by SchneidersLaden and very pleased to see Gammon spreading knowledge about modular synthesizers and encouraging people to play with instruments they may not have even heard of before.

The workshops start with the very basic terms and guides the participants all the way to be able to play freely and improvised on modular synthesizers. The participants work independently, max. in groups of 2, on the Modular Synthesizer. They are thus directly involved in the process of creating the sounds and are responsible for their individual sound design.
Fundamental knowledge about electronic sound generation is imparted in the “hands-on” process. Ten modular synthesizer systems are designed in such a way that the different configurations create an ensemble with different musical voices. The resulting sounds are the basis for a joint composition, which is recorded with a graphic notation and then played live.
Working with an analog modular synthesizer not only conveys the emergence of electronic music, but is also an important basis for digital electronic music on the computer.

The musician and sound artist Gammon has been active for many years in the field of music and art mediation with various workshop formats. In 2013 he was awarded the international music mediation prize “Junge Ohren” and won the German competition “Kinder zum Olymp”. For more than a decade, he worked successfully with the Thilges3 collective on an international level. The trio used almost exclusively Doepfer‘s Modular Synthesizer for their installative performance formats.

17th DIGITALANALOG – Festival Munich

[et_pb_section bb_built=”1″][et_pb_row][et_pb_column type=”1_2″][et_pb_text _builder_version=”3.0.60″ background_layout=”light” text_orientation=”left” border_style=”solid”]

The already 17th edition of DIGITALANALOG took place on 20th and 21st of October at the Gasteig in Munich.

DIGITALANALOG is an audio-visual cultural and art festival organised by the Holmeier family on an annual basis and free of charge for visitors. The Gasteig is a cultural center with an integrated philharmonic orchestra, which is unique in Munich, due to its design and its size.

As in 2015, HerrSchneider took part at DIGITALANALOG this year with his self-developed synthesizer carousel on the 1st floor of the foyer, so that interested visitors could be introduced to the subject of patching and button turning on individual modules for the purpose of generating sound. Arno P. gave support and encouragement for those searching for sounds and rhythms.

It was particularly striking that there was a pleasing number of female guests interested in electronical sound generation, which was easily recognizable by the visitors of the synthesizer carousel. For example a young girl explaining her two companions what an envelope module is, how it is used and how it would influence the sound. It was very nice to see that there was such an enthusiasm for the matter of modular synthesizers. Apart from that, the carousel was well visited during the opening times and partly a queue formed at the entrance to the carousel.

It is also worth mentioning that our neighbours, with their “Das Labyrinth des Vergehens” (a lavish and magnificent audio-visual installation) had booked the artists Ströme and Panic Girl – so there was a small SUPERBOOTH17 reunion in Munich. Unfortunately, Dieter Doepfer, who was also supposed to participate there, was hindered due to illness. We wish you a good and swift recovery!

DIGITALANALOG presented a pleasant and colorful potpourri of electronic music as well as alternative bands who played Ska or Britpop. The visuals were quite impressive during the live gigs and also outside, where there was also a screen set up for the smokers on which live images of the interior were projected.

We are looking forward to DIGITALANALOG 18!

Science meets Doepfer at DESY Research Center Hamburg

A special kind of collision occurs at the DESY research center in Hamburg this autumn: 15 artists from all over Germany will be exhibiting their works on the subject of “Dark Matter” on the research site. The works are a result of an intense exchange of ideas between scientists, working in the field of Dark Matter and artists, who are active in various fields ranging from painting, graphics, photography and film, sculpture, installation to sound and multimedia. It is the first art meets science project at DESY. Housed in the research and test halls, where the researchers will continue to operate during the exhibition. Therefor art will not only be a guest for one month, but will also become part of the research.

And as if this would not be interesting enough, there will be artist and musician Chris Pfeil playing on the perfect synthesizer for this event: The Doepfer Dark Energy alongside Doepfers Dark Time and R2M.

The Dark Energy by Doepfer has led many musicians to the dark side of the force. With its semi-modular approach, a convincing concept with MIDI, CV and USB interface and the powerful sound, it inspired people to integrate analog synthesis to their mobile rigs and home studios. It can be considered a pioneer of the affordable-analog-mono-synth revival that can be seen in recent years.

Artists and scientists met in a workshop at DESY to explore the subject of dark matter. Why do we know that there must be dark matter, how do we try to discover it and how could its discovery change our view of the world? The artists also reported on their work and work processes, and it became clear that scientists and artists have a lot in common. Experimentation, problem-solving strategies, the processing of failures and, of course, curiosity distinguish both professions.


A special thank you goes to Herr Auge Lorenz for his very nice picture “Klänge der Dunkelheit”.

These are the opening times for the Exhibition:

18.10.   Lecture and guided tour

25.10.   Lecture and guided tour

31.10.   International Dark Matter Day with short film programme

4.11.     DESY DAY (Open Day at DESY)

MIXERS: Arrel, Doepfer, Endorphin.es, Frap Tools …

In eurorack it is often overlooked that you can go way beyond simply mixing audio signals, but with the right mixer you can do so much more. Nowadays there is a huge variety of mixing solutions available. The range of mixer products for eurorack goes from simple some-input-one-output solutions, to mixers with stereo channels and Aux-send/return, to mixers with built in effects, CV-control of amplitude pannnig … and so on. It is therefore important to think about what you really want from a mixer. Even if you only need to mix two or three different waveforms there are plenty decisions to make:

Do you just need different and variable levels? Then the classic Doepfer A-138b seems suitable. If you know you simply want to mix three waveforms and save some of your valuable rack-space, you might choose the Doepfer Micro Mixer. But what if you want more? Mixing three waveforms in a small space with the extra bit of saturation when you push it? Then the Manhattan Analog DTM might be the right choice.

Need more advice?

There are even more things to consider. Do you have stereo signals to process? Do you need a separate headphone out? Do you want your mixer to be another tool for sound design? Is the mixer the last device before the audio signal hits your audio interface or tape machine? So below you will find a short list of some interesting mixer modules that could not be more different.

Mixer Banner

And we are starting big! Not only in regard to hp, but also in regard to sound. The first module on this short list is the Arrel ER-100:

Arrel Audio ER-100: High-end stereo mixer – really this is high-end! If one of your main concerns when looking at a mixer is sound quality, look no further – eight channels, panning, two aux inputs, two insert, sends and returns, two main and two monitor outputs and a stereo headphone connector. Due to outstanding sound and built quality the module plays in the same league as professional summing units, well … it is a professional summing unit. And you can connect the ER-100 directly to your studio equipment, there’s no need for an output module. It won’t get any better, this thing completely convinced us!

Doepfer A-138 Series: The Doepfer mixer family offers solutions for pretty much any situation, they are simple, reliable and affordable. From a simple 2×3 Micro Mixer, to an expandable Performance Mixer system, to the Matrix Mixer and many more – Doepfer has all grounds covered.

Endorphin.es Cockpit: More than just a mixer – The Cockpit can not only be used to sum up mono and stereo signals with modular or line level, but also as an effects insert for smartphones and tablets. Additionally, the module offers a ducking compressor plus sidechain input. The Cockpit packs a lot into its 6 hp, but you must keep in mind that you need to use special cables to take advantage of all its possibilities.

Hexinverter – Hot Glue: The modular hot-melt glue gun is a four-channel bus mixer with a number of different outputs, FX-Send as well as a soft-knee compressor in studio quality and a voltage controlled analog distortion. Both distortion and compressor are normalized to the mixer but can be used individually. For what it costs the Hot Glue is a very interesting versatile solution for pretty much any system.

TouellSkouarn – Sonveskan: This is a three-channel mixer, which was built using discrete components like germanium transistors. All in all – lots of gain, voltage controlled feedback, a mute switch and a direct output. By combining several channel strips, it is possible to create very(!) wild effects. The mixer’s main channel features an equalizer with two bands and another gain stage delivering more distortion. – A great module for people who like it rough!

Verbos Electronics – Scan + Pan: Four channels with voltage control of level and panorama position may be usual features, but an extraordinary one is the voltage controlled scanning between the channels. Verbos always surprises with solutions you won’t find in many other modules and keep convincing us with the creative opportunities you get from their modules.

Then go through all mixers here, or configure your own mixer with Frap Tools CGM:

FrapCGM Banner

Frap Tools – CGM: The Frap Tools CGM System lets you combine input channels with summing modules for groups and output modules. The modules offer direct-outs, several aux sends and solo, mute and PFL buttons. Pretty much everything you know from your stand-alone mixer, but due to the flexibility of its modular-modular design you can built the perfectly suitable mixer for your rack – in your rack. And the CGM offers very good build and audio quality across the entire mixer range.


This is by no means a complete overview of available modules nor a full review of the discussed modules. The what about… text are here to give you new ideas and maybe another perspective on things. All these modules offer more features than we have talked about in this post.

Fideuà and synths – Modular Day Barcelona 2017

[et_pb_section bb_built=”1″][et_pb_row][et_pb_column type=”4_4″][et_pb_text _builder_version=”3.0.60″ background_layout=”light” text_orientation=”left” border_style=”solid”]

Modular Day Barcelona was a complete success again. The halls were full of interested and interesting people and the many workshops were well attended. There were probably more guests on site than last year. A rain shower had its premiere this year, but as it drove the visitors straight into the exhibitor’s hall, it was not really unwelcome at all, except perhaps by the chefs that were cooking a Catalan paella (Fideuà). For them it was quite a fight to keep the pan dish from degenerating into a fish soup… which luckily didn’t happen!

On the exhibitor side there have been the usual suspects: Befaco, Erica Synths, Endorphin.es, FrapTools, TouellSkouarn and many more. For the first time Mr. and Mrs. Verbos personally honored the Modular Day Barcelona.

Like in the past years speakers were strictly forbidden at the booths and only headphones could be used. Our systems were well prepared with Doepfer A-139-2, ACL Audio Interface and Vermona Twin Out. And as a result of that regulation the overall atmosphere was very relaxed. Most interest could be raised by new modules. For Doepfer, the A-111-4 Quad Precision VCO was quite well received. A lot of VCO in a small space. Approximately 100 Euro per VCO are a really good deal. Thanks to the MS-Matrix and a funny stereo patch, ACL caught a lot of attention underneath the headphones. The new Discrete Core Ladder VCF in particular has created a positive impact. The striking appearance of the Quad Envelope prototype from Vermona caused lots of curious glances and so the news like randomRHYTHM or quadroPol didn’t get lost in the unified and beautiful Vermona look.

In addition to pure modular synthesizers, the Taula4 Rotary Mixer and Podium Mikrokosmus (active summing mixer) have expanded the shown product ranges with the presentation of audiophile gear made in Spain. Hopefully we will see more of these products at SUPERBOOTH18. In contrast to the last years the evening concerts took place only partly at the actual venue, the hangar. The program was about as strenuous as it can get. Party till 05:30am (at least officially) and then start again at 10.30am. So you had lots of opportunities to have a good time, but not for sleeping.

We want to say thank you to the Befaco Team who have handled everything in a very professional and friendly way. See you at SUPERBOOTH18!

NAMM 17 – Doepfer

IMG_4757The inventor and most classical eurorack brand Doepfer now released their version of a mixing desk inside the system in a definitely modular form. Plenty of their modules are also available now as a so called vintage version in black so they are getting back to the classical shine of a (moog-style) modular taking it to the complex possibilities of nowadays modulars. The existing Doepfer products in silver aluminium are classical themselves in between, still built in a very high quality for mostly very affordable prices.

The earlier combination of A-138-O/A-138-P as a simple four- to sixteen-channel Mixer can very soon be expanded by the A-135-4-A/B/C to have the 4 to 16 channels added with CV-controlled AUX, PAN, LEVEL and MUTE parameters. The modular component 135-4C is a four channel envelope follower opening a new horizont of level control in eurorack systems. Apart from this, Doepfer was presenting the comeback of their high end VCO that had to be discontinued once their curtis chips was no longer available (as far as I know). Now the “new” A-111-2 is available in a wide and a very small version, see all details shown by Patrick Detampel in this Video:

NAMM2017 started today

IMG_4738.. and there are plenty of modular manufacturers getting together again. Elektron released an update on their drummachine in a new casing, Pittsburgh shows his passion for slotmachines and Harvestman is offering a huge synth together with Malekko? This is just the little impression that I got from yesterdays look down thru the links on twitter. The biggest news today will be the funny new president (sorry, not funny) but still there will be other news n stuff to be shown over here in pictures and links… btw we learned to make pictures available in big again, so please feel free to just clic on the small ones..
lets make truth big again?

IMG_0468Running around on NAMM there are Carlo Krug, Sebastian Baumann and Henning Schonvogel for SchneidersLaden with the job to buy. For the Alex4 distribution company there are Rene Margraff and Jan Mueller with the job to sell, there are plenty of manufacturers themselves around them with the passion to play and finally there is Patrick Detampel with the passion to explain.
So if you have questions regarding the upcoming SUPERBOOTH17 end of april probably Patrick could help you best.

Please have a good time all together, be a peaceful and constructive community to get together again very soon here in berlin, europe for a warm welcome of our spring. I am very much looking forward to welcome YOU on board making the wonderful ride on the river again. And there is plenty of other reasons to participate again.
With warmest regards, HerrSchneider, Berlin


Anzeige_Vintage_LokomotiveNot just their best VCOs ever but also a complete Mixer system with smart black frontplates and nicer knobs are now available by our most classic european eurorack brand DOEPFER. All their lastest news and products can be seen and tested on the NAMM show in Anaheim (CA) now, visit booth #4911 (Alex4).

ALEX4 has Moved

ALEX4You mostly dont have to take care about this, but the doepfer and others-general distributor ALEX4 moved to a new adress in the north of berlin where they have a bigger stock room and a nicer office to let our musical instrument shops over europe get the stuff they need from. But even there .. you can not find them next week because they will all be on NAMM showing the modular world to those freaks in the Los Angeles area who are not moving to washington to celebrate their new president at the same time. So if you are one of those living in the US and meet us in Anaheim near Disneyland to check for the latest news of AJH Synth, Audio Damage, Birdkids, Doepfer, E-RM, Endorphines, Frap Tools, Haken, Kenton, Sherman, Verbos, Vermona and others .. see you.

Modular System for X-mas?

.. synthesizers could make one happy, too! If you plan to order something that you would like to have under or instead of a christmas tree – lightning could be even better – we strongly recommend to plan it and ask for availability in time. Usually this is not done in a day and we will recommend you to oversleep your indivdiual selection and constellation, but .. please call in or come in or start reading about it – if, then –  now.

Workshop with special guest Touellskouarn Nov, 10th


Come over on Thursday, November 10th for a special  introduction to modular workshop  with our friends Touellskouarn!  Our goal is to help you get familiarized with the modular so that you can confidently make your first patch! This time around you will also have the opportunity to learn directly from Gaël of Touellskouarn how to add life and color to this first patch using feedback and fuzz with the likes of the Strakal Brulu and Sonveskan modules.

Although we are nerds we won’t get too technical.  Along the way we will show you basic patch techniques as well as talking about how one can start applying them to make music. Starts at 6pm / At our showroom / Kotti above Kaisers (ring bell: schneidersladen) / The workshop is limited to 12 participants:

>>> Please register with Camilo: co@schneidersladen directly now !!! <<<           – See you there!!! The schneidersladen showroom team



If you dont own a modular so far and IF you would like to know about it and IF you understand the german language, here is the latest issue of an intensive introduction on how do I get this started.. with Patrick Detampel as a guest of Non-Eric alias Muso-Talk ..

Doepfer A-100 goes Vintage

The most popular Doepfer A-100 modules are being released in a Vintage Edition, having a black anodized faceplate with black legending and old-school knobs that have been custom-made for Doepfer.

Constantly new ones are added to the line but so far following modules are in stock at Schneiders Laden:

EDIT: new ones came in on April 19th:

NAMM 16 – Sputnik Modular

Unstoppable, lilac-colored Roman Filipov aka Sputnik Modular has a number of new stuff – he hasn’t yet decided which will go into production first.

sputnik-16stepseq The 16-step voltage source is like the small 5-step but way bigger.

sputnik-multisegment-seq sputnik-multistage-seq

Dual Multisegment Function Generator and Multistage Voltage Source are both really complex digital sequencer modules, especially the first one is pretty incredible.

sputnik-freqshifter Roman licensed late Jürgen Haible’s all-analog Frequency Shifter circuit! The booth was noisy so we couldn’t really tell how good it sounds but it’s really promising.

sputnik-seqfilter The Sequential Filter design resembles an existing 200e Buchla module. It comprises of three identical filters which feature frequency, resonance and level control. The eight-step sequencer saves all three parameters into one sequence and eight sequences can be stored. Proceed from step to step and from sequence to sequence with clocks. Look at one self-oscillating filter as a sine oscillator with VCA – the module can be used as a triple synth voice with sequencer as well!

sputnik-dualegLPG The Dual Envelope & Gate combines the envelope and lopass gate functions of other Sputnik modules to one compact module.

NAMM 16 – Doepfer

Our friends Dieter and Sibylle again showed up again with two huge systems and a couple of small ones, displaying as well all their recent modules as new units and prototypes.

Nice knobs, I has them


  • A-168 PWM Generator is able to alter pulsewidths of inputs e.g. triangles by changing them into squares with variable width. Basically it’s a comparator but smaller than the A-167.
  • A-110-3 and -6 are early prototpyes of Thru Zero VCOs capable of generating more than just sine waves.
  • A-106-5 SEM filter might be released in a vintage special edition with cream faceplate.
  • A-121-2 is a protoype for a new multi mode filter with individual inputs.

Doepfer vintage series

The most classic synth A-100 modules needed for creating an “old-fashioned” synth will be available in a vintage edition, sporting nicely black anodized faceplates, white legending and custom-made knobs. Price difference to standard version depends on the amount of knobs used for the module.

On top of the black cases you can see the new, universal, Miniature Power Supply with IEC mains socket.


The final pre-production version of the A-157 sub system was shown – a complex trigger sequencer with 8 rows, each with plenty of options like direction, first/last step, step inversion and mirroring. The expanders are included and can be mounted where you prefer them to be.

This happy guy rocked the Doepfer booth and had so much fun creating really good sounds.

Promotions & Workshops

20150924_182836Camillo Ocampo made another constructive workshop teaching basic modulars on Analogue Systems and Doepfers mixed eurorack systems last week at SchneidersLaden.

Dates and happenings like this are quite en vogue at the time worldwide, so .. as a rep for the Doepfer Distribution Patrick Detampel is currently in Barcelona on the modular day showing the AJH synth, Doepfer and Vermona modulars in general.

Next week you could meet him in Budapest, Hungary on the Budapest Music Expo (Oct., 2nd til 4th) with a big Doepfer System, his Verbos Case and many more stuff around. On that event you will also be able to see the RS8000 by Analogue Systems combined with a french connection.

For the american friends of EUROrack Patrick D. will be on machines in music in NYC/Brooklyn (Oct., 17th-18th) to show his Subharmonic Groovebox by Doepfer together with the E-RM Multiclock, AJH, Vermona and the Endorphin.es.  So far for now?

Analogue Systems?

Bob-WilliamsAccording to Mr. Bob Williams originally idea, his brand and product line – the integrator modular system a.k.a. analogue systems – will be sold in ready to go casings and wooden cabints again. They will come – just completely mounted up the way you want them – with a full five years warranty from now on.

After having had too much trouble from circuitries damaged with wrong or misused connector cabels, with (others) power supplies that did not serve enough ampere for some of the high class functionalities, or selfmade casings, where the modules has been returned once they did not fit, taking this excellent products out of the mixed systems is indeed a bad decision for the idea of the common eurorack, but a good one for the position of analogue systems.

aorsThe integrator system can be configurated on a comfortable modular planner and should be coming from the production to your retail store within a month now. For any kind of questions please get back to your modular stores over europe.

on the namm again..

Marc_Shawn_Andreas_BillAfter European products are cheaper for our friends in the US now, we will join the upcoming NAMM show to let you touch and listen to the germans and their friends latest products on stand 6996 in Hall A! Dieter Doepfer will be there, Vermona, MFB, Manikin, JoMoX, Kenton, Eowave and BR-Laser from Austria having the Terminal in his case. We will be next to the stand of our american friends such as Verbos, WMD, Snazzy ,4MS, the Harvestman and many others probably brining loads of NEWS.

Join Europe: iTs CHEAP now!

The european money is cheaper than ever at least for people in the US and the UK now. Unfortunately for europeans the products from these countries are much more expensive now .. the other way round, so… a lot of our prices for modulars and others finally had to be increased now. So please accept the raise from 7% to 10% average with some very attractive modular series,
… we are sorry. New prices are online and valid now!

.. And finally: Be welcome and  join Musikmesse in Frankfurt/Germany – it will be April, 15th to 18th this year – spring time with even more new stuff for even better prices, .. perhaps!

NEW Modules by Doepfer ..

Tomorrow Friday, 5th after 6pm Thomas K. will make another modular workshop at SchneidersLaden showing and introducing several smaller systems including the most prototypes of the brandnew Doepfer  A-100 modules to be released on the upcoming NAMM show in January. If you want to be informed about these updates, if you think about starting another small project with a modular system, register for a place in tomorrows workshop with a simple email to Thomas K., its free and we will have a beer, coffee or a water included.

The workshop will probably be done in time to still be able to see the gig as follows..


HerrSchneider2014.. is not on facebook and a bit weird at the time … Sonic State made this interview once they was visiting berlin and I was surprised myself, what I am telling there. Its a lot about our friends making stuff and some things about personal history and .. some good sounds on the modular in the end. Thank you Edd.

Mellotron Sounds ..

P1120587The sounds of the Memotron – the (digital copied) original digital copy of the (original copied) mellotron – are  a collection of 100 included sounds from now on! All the remaining memotron units that will be selling new should have this. These ones are getting short anyway, a new model will follow up soon.
Join the NAMM show in Anaheim to check this out: Manikin electronic, Doepfer, Vermona, MFB, JoMoX, EOwave, and all the american modular brands will join the american Music show in January with a collective stand in Hall A. So if you can, be around from January 22nd til 25th, 2015.



_MG_8439_0217_klOn Thursday (September, 24th)  the DJ convention Dancefair will start for the very first time on the island Ibiza. Apart from “DJ companies” like Roland, the SAE and others some more attraktive hardware units by Doepfer, Vermona, Sherman, Koma, MFB and Manikin will be shown by Philipp and Franz from Schneidersladen on behalf of SchneidersBuero, Berlin. So if you are around have some fun and make some sunny sounds with them. Enjoy.


electronics-repairs2At Just Music in Hamburg the FIVE DAYS, a workshop series or promotion started today. At 2pm there will be an informational two hours about Doepfer, Moog, Mellotrons & more held by our new A-100 buddy Chris Miller and others.
