Feature-complete spaghetti

Loads of things have come our way. Loads of things non-synth. And this took time, loads of time. But here it is, in all its glory: a more-or-less feature-complete model of the ST4:

There’s no display connected since it couldn’t possibly fit amidst all this wiring terror, but for the rest, everything just works:

  • All four voices multi-mode VCF action
  • All filters are fully hands-on controllable per voice
  • All four stereo voices VCA action including panning per voice
  • The three ADSR envelopes and two LFO’s are fully controllable
  • Sampling and bitcrushing, voice detuning, voice modes
  • Everything can be controlled by MIDI as well

Next steps are improving performance (loose wires give a bunch of crosstalk, it’s unholy), adding the display and just replacing all that breadboard with a decent PCB… and putting it all in some preliminary casing.
