[WIP] Shifty Shaper

This project is about “upgrading” the Cadet VCO with more waveforms.
However, this will be done with Lunetta style Shift Registers, Counters and R2R ladders,
so the waveshapes are stepped. With filter switches these can be somewhat “smoothed”
The idea is to have alternative Horizontal waveshapes to use for modulating Vertical VCOs

Features:

  • Input (can be any 0-1v VCO output) → comparator
  • Shaper outputs: staircase Ramp / Triangle / Saw / Chaos
  • Switchable Filters for each output
  • Comparator Squarewave output
  • Patch header for weird waveshapes (Chaos)
  • CMOS based, so expect rough shapes

Project stage: breadboarding & using the VEB2 (video experiment board) to test each design block. Schematic design is halfway done
