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 lots of analog drum voices; based heavily on Moritz Klein's schematic, with features added from Skull and Circuit's VCA v1.3. D952ec97f3 Go to file f63cfba954 Embiggen traces, add teardrops updated C5 footprint & tracing; schematic annotation updates the potentiometer pads and trace routing to de-bodge the pots. D5bfb6e27b 's notes on updating the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation.
