Drum module

Doof is not another 808/909 clone. The topology is common enough in many drum synths: Trigger circuit, envelope follower, VCO, VCA, but the actual sub-circuits are slimmed down versions of the dual OTA VCO and VCA from the Matrix Mixer. Very wide ranging and shape control squares up the waveshape to get a nice raspy rattle to the sounds.
