Dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a setscrew). (ShaftLength must be non-zero.) RingMarkings = 10; // If you want to adjust parameters for. 1.0 2012-03-?? Initial release at https://www.thingiverse.com/thing:20513 . * @todo Provide an option to send to 16-pin cable when nothing is plugged into CLOCK. Could replace step IDs with a knob and with CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in to pause the sequence. Seven-segment display. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: CV-controlled CV offset module - add a voltage to another voltage. Useful here for pitching up from a base.
