NAMM 2018 – Catalyst Audio

David Small added some new modules to his line of Buchla 100 series clones for Eurorack. Model 114 is a dual square wave oscillator. At first glance, the design may looks limited, but let me assure you: It is awesome! Thanks to several inputs and outputs per VCO, you can do frequency modulation, cross modulation and amplitude modulation at the same time. – The results range from fat and smooth to weird and nasty.

The second new module is the Model 195. It consists of two low-pass filters with adjustable and voltage controllable cutoff frequency as well as a band-pass circuit with four fixed outputs. The Model 195’s sound could be described as old school analog. The third module, Model 191, is a multi-mode filter with individually usable high-pass, low-pass and band-pass channel. Each filter features a big cutoff knob plus several FM inputs. There are no resonance parameters. However, there is a manually and voltage controllable bandwidth section to shift low-pass and high-pass in opposite directions. We can’t tell you anything about the module’s sound yet, as it wasn’t functional. That said, it should be noted that its full name is Model 191 Sharp Cutoff Filter.

Furthermore, Catalyst Audio showed the Model 140 Timing Pulse Generator, a rather complex clock source, at the NAMM show 2018. On to of that, the Model 190 dual (spring) reverberator was introduced. This module is not a Buchla clone, but David’s very own design. – He said that every good Buchla system needs a spring reverb.
