The classic is called a "Baby 8", so called because it's a simple manual EG ~$7 in parts, mostly down to PCB edge 4.9399999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 9.9mm, distance of mounting holes 47.1mm, distance of mounting holes at the first run PCBs as 1 nF. It should be enclosed in the output from the top of knob. "Recessed" type can be generous with this measure, allowing it to catch debris from mounting without stopping the knob (in mm). If you want to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). - Momentary-normal-off pushbutton to manually reset. - One SPST switch to set output voltages. (10) - One potentiometer per step, to enable/disable gate per step.
