| PAD ID | Function |
| A | Trig In |
| BPO | AC coupled output |
| C | Signal In |
| DCO | Main (DC) output. DCO on PCB. "6" in panel diagram above |
| D | optional "bipolar" output |
| E | exp CV input. So called "1V/oct" |
| F | CV input "VC IN" |
| FA | CCW end of "VC IN" pot |
| FB | WIPER of "VC IN" pot (G and T on the wiring diagram) |
| FC | CW end of "VC IN" pot |
| H | WIPER of FALL pot |
| K | WIPER of RISE pot |
| M | END or GATE (output) |
| MA | RISE/FALL/BOTH switch Rise contact (I and 2 on the wiring diagram) |
| MB | RISE/FALL/BOTH switch Fall contact (J and 3 on the wiring diagram) |
| MC | RISE/FALL/BOTH switch common (or use the common 0V wire as per the diagram) |
| LA | LED anode |
| LK | LED cathode |
| "U" | U connection on the panel wiring diagram connects to 0V. There is no U on the PCB. Use one of the pads marked "0V" instead. |
| W | 0V power connection |
| X | +12V power connection |
| Z | -12V power connection |
