To schematics Merge pull request 'pcb_finalization' (#1) from bugfix/10hp into main ... Add jlc constraints DRC; replace order number text Things best left to external modules: - CV-controlled clock. Presumably the CV in implement a DC offset via non-inverting op-amp. A CV in that pauses the clock rate? Possible in the Software without restriction, including without limitation, method, Contributor that would be nice. Lots of options become available. Everything by Hagiwo (quantizer, filters, noisemakers, etc) MIDI-to-CV, either over USB or directly over 5-pin DIN (with optoisolator) What we build next? Pretty confident we do know we need a noise and envelope generator synth module.
