The Quanalog Boubou is a combination of 5 voices of filter-based analog drum synthesizers that cover a basic drum set. The idea of using filters as a source for drum sounds isn’t new at all. It is a great technique for creating interesting sounds that react very dynamically to the input signal.

The video focusses on the rather usual use cases for a drum machine. But because each drum engine is basically a signal processor with an analog filter at its core, they can also process other drums or alternatively other modules.

Each sound has been carefully designed with a specific analog filter structure to create a great drum feel, from the lower to the higher frequencies. It really is a fun module because it is so responsive. Creating lively hihat patterns is super easy by simply adjusting the gate length – k generating interesting grooves and unusually shuffled rhythms is easily achieved by using the retrigger option on the tom sounds.

At first the Boubou doesn’t seem to be too versatile, but it is. Just send one of the sounds through another – they are filters in the end – and you get a new variety of sound. It is highly recommended to experiment with the gates/trigger/envelopes you send into the trigger inputs, because they can have a big influence on the sound.
