Continue? 5cacbfea2e Add polygon calculation for wing plates Seven-segment display. Can be done, but requires a trigger-sized pulse on input. - Portamento (aka slew rate controller aka glide). Knob version fairly simple. - CV version maybe possible, but a much bigger circuit. Haven't found a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Latest commits for file Images/IMG_6753.JPG **Untested hardware and software — Do not connect the Normal pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary? Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF ~$8 in parts.
