Can't believe nobody has released a drum module called DOOF yet....wtf?
Anyway, its 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. will get a demo up soon.
