These days ($3/ea on amazon, maybe fakes) VCA MK's VCA Everything by Hagiwo (quantizer, filters, noisemakers, etc MIDI-to-CV, either over USB or directly over 5-pin DIN (with optoisolator) What we build next? Pretty confident we do know we need a noise and envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: make power connection traces larger; MK uses .6mm -- this means from the centerline of the board, connecting a trace on one side when convenient. You can use one on both sides, or do partial planes where convenient.
