A 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 work, but with an attenuator, intended for use as tremolo Manual offset knob 63579cf959 Add notes about UX component wiring 55ee65a5e9 Checkpoint after tweaking footprints some more, starting over at 14hp PCB initial layout, no traces One SPST switch to set output voltages. (10) - One potentiometer per step, to set output voltages. (10) - One per step, to indicate current step. (10 - One potentiometer for internal clock signal (possibly external).
