summary: |
  Eighties Bass is a complete mono bass voice using 5 saw oscillators plus optional white noise.
  Main sets filter cutoff, X sets pitch offset, and Y sets resonance.
  Press switch down to cycle filter mode (LPF/BPF/HPF).
  CV In 1 provides pitch CV, CV In 2 offsets cutoff, Audio In 1 modulates detune, and Audio In 2 modulates noise amount.
