UI: One potentiometer per step, to set output voltages. (10) One potentiometer for internal clock signal (possibly external). Commonly called a "Baby 8". Final tweaks, version submitted to JLCPCB on 20240124 v1.0 Add CV in to pause the clock oscillilator an external clock. One idea: add a voltage to another voltage. Useful here for pitching up from a base. 11 SPDT switches 1 rotary switch - 9.5mm, +5mm extra space available - mini toggle switch could be mechanical difficulties using 9 mm. See [build notes](build.md). \*\*\* A-3586, A-3587, and A-3588 look similar but is normally closed rather than normally open and will not work. Ask me how I know this. And by "ask me" I mean "shut up".
