Fix pots going the wrong side of D35, but other options exist. Single-step button (SW13) isn't producing a high enough voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a capacitor / resistor pair, see Fireball's hard sync to schematic, laid out PCB with on-board components PCB initial layout, no traces "copper_text_size_h": 1.5, "copper_text_size_v": 1.5, "copper_text_thickness": 0.3, PCB initial layout, no traces One SPST switch to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). Momentary-normal-off pushbutton to manually reset. More repo cleanup, adopt github .gitignore file Select.
