Could replace step IDs with a Work for part through the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power - MK uses a CA3080 OTA, an expensive and rare chip 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 these in a rack, if not a half dozen.
