Big board, requiring one 8-pin, one 14-pin and one with an attenuator, intended for use as tremolo - Manual one-step-forward via momentary push button. CV out, with probably +12v gates. - Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). External reset via socket. - External reset via momentary push button. - CV Out - 1K to U2-14 Case Out - Diode from rotary pin 13 - CV out - CV out /* [Default values] */ // // top horizontal rib // one more vertical to mount a circuit outside the full dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the code they affect.
