Drums 808
18 May 2022
Two drum modules - both based on 808 style circuits.
Mr. Hat
First up, a hat and snare module. A pretty basic 808 style schematic, and I've added on a vactrol to make the decay time controllable by CV. Custom designed PCB to fit the hat and snare circuits into a slim 20mm module.
Ms. Kick
And next, an 808 based Kick drum module. This was done using a schematic from M4TM, with a few changes. I've added a bass switch to drop out the pitch control, to get really super low bass if you want. The clipping and pitch control came from the M4MT schematic.
Board is a prototyping board that I have designed - a large area for building, busses for +12v, -12v and ground, and mounting points for jacks and controls. I figure for these one off modules I don't need 5 or 10 copies, so this board will hopefully be useful for multiple projects.
