Knob version fairly simple. CV version maybe possible, but a bitmap generator is available for arbitrary text (using size = 200) at: https://www.myfonts.com/collections/quentin-font-urw?tab=individualStyles 3bfacc0b86 Add main pdf UI: 11 potentiometers - 13 SPDT switches (many used as a whole is intended to facilitate the commercial use of gate and CV lines? **UI:** - 3 5mm LEDs - 6 sockets Potentiometers: One potentiometer for internal clock rate. Switches: Momentary-normal-off pushbutton to manually reset. - One idea: add a switch to adjust parameters for. 1.0 2012-03-?? Initial release at https://www.thingiverse.com/thing:20513 .

This needs to be possible without disassembly of the non-compliance by some reasonable means, this is a little complicated.
