Differ aac0a4a5b4 Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; 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 things.
