See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with an eye towards doing it all in one module with a capacitor / resistor pair, see Fireball's hard sync 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 circuit that generates a sequence of envelopes or as an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be passed in as parameter to eurorackPanel threeUHeight = 133.35; // overall 3u height panelOuterHeight =128.5; panelInnerHeight = 110; //rail clearance = ~11.675mm, top and bottom boards.
