BadumTisss is a snare/hi-hat module.
The core sound of the circuit comes from the ring mod. Usually it will process the noise source and the VCO, but feel free to plug in the output from another VCO and get some nice sounds. You can use CV to modulate the VCO frequency (NOT 1/oct) and control the attack/decay time. This allows the creation of all kinds of intricate sounds, best heard in the 2nd half of this video.
