summary: |
  Goldfish is a multi-mode stereo delay/looper with synchronized pulse/CV outputs. The switch selects
  record, delay, and play behaviors. Audio is streamed to flash (IMA-ADPCM), so loops/delays run from
  ~55s on a 2MB card up to ~9min on 16MB. Pulse inputs provide clock/reset (and gated recording); the
  CV/audio inputs modulate delay time, playback position and speed, and the generated CV/pitch material.
