First commit of a prototype ComputerCard-based 00 Simple MIDI card, put in a v2_prototype subdirectory of this card.

New features:

  • Web-based auto-calibration of CV outs and WS oscillator trimming
  • Supports USB MIDI Host and Device
  • Pitchbend (±2 semitone)
  • Handles multiple notes down with overlapping note on/off more gracefully

Remaining TODOs:

  • Lots of testing
  • Calibration of audio/CV inputs
  • Calibration modes for standalone Computer and Workshop System calibration from an external 1V/oct oscillator
  • ?

Version for testing at https://chris-j.co.uk/misc/simple_midi_2/ with firmware https://chris-j.co.uk/misc/simple_midi_2/simple_midi_2.uf2 . I'll try to keep these up to date with the version here.

I'm leaving as a draft PR for now as this is not 'my' card to edit. Everything is in a v2_prototype subdirectory so it won't overwrite the old card.
