E6b834b08c Fix floating pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary? Alternative: Midi -> CV We could also go to same bus run/stop 2x Pushbutton switches, all 2pin: - reset Pots, 3-pin: - Glide attenuator (B10k) (join two left pins from below Pots, 2-pin: Glide, manual (A100k) (two left pins, from below Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for film; is film needed?
