A notable issue with this design is the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation. Glide fix glide fix glide fix - 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 more complex module, several variations on the right // cv out (j7/j6) // pause (j18/j19 // run/stop (sw14 // 1 rotary switch, 5+ positions 10 LEDs - one per feed.
