Brief Overview
BoomTschak is an Eurorack module for synthesizing drum and percussion sounds. It contains a
VCO, three envelope generators, a noise source, a multi-mode VCF, and several VCAs. Its
circuitry is completely analog.
Below is an image of its panel and a description of the controls. This summary will cover just
about everything that you need to know to use BoomTschak, but after this summary we’ll
provide more detailed descriptions and some background information.
If you can’t stand reading manuals, we’ve got you covered. There’s a video providing an
overview of BoomTschak’s operation on YouTube here:

Knobs and Switches
– sets the frequency of the VCO
– controls how much the pitch-bend envelope generator changes the frequency of
the VCO. This is a bidirectional control; at its center position, the EG has no effect on the VCO.
– sets the decay time of the pitch-bend EG.
