To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals 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 know we need a diode to U2-3 - Clock Rate - variable resist +6k between U2-8 and U2-9 - Reset Socket to U3-3 = capacitor measurement roughly 15nF (has a resistor as well - Once/Cont 11 Toggle Switches, 2pin: - all step switches (all go to same bus) - run/stop 2x Pushbutton switches, all 2pin: reset Pots, 3-pin: - Glide attenuator (B10k) (join two left pins from below - Glide, manual (A100k) (two left pins, from below) Pots, 2-pin: Glide, manual (A100k) (two left pins, from below) - Clock In Normal - 1k to U2-8 (AND NOT short to.
