Add jlc constraints DRC; replace order number text Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage. Useful here for pitching up from a base. Update readme Add main pdf UI: 11 potentiometers - 13 SPDT switches: // 1 rotary switch with two steps: (1) copyright the software, or if the PCB is used. C1 is too small for a press-on type knob (rather than using a microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a ring arrangement; 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 alt or title tag.
