Challenging PCB and/or print job! 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 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 2cbdb94ba9 updated C5 footprint & tracing; schematic annotation 2cbdb94ba94f485ce4abcb1f14e2e5f15d016647 updates the potentiometer pads and trace routing to de-bodge the pots.
