Name: You spin me round
short-description: Playable rotary speaker with separate horn/drum inertia and an Inside perspective.
summary: >-
  A hardware-tested mono-to-stereo Leslie-style rotary speaker for the Workshop
  Computer. Main sets speed, X opens up movement and stereo spread, and Y adds
  cabinet drive. Switch between slow and fast, or hold Down to brake and release
  to resume. Outside is the default; hold Down at boot and use Main to select an
  exaggerated Inside perspective. Release candidate based on the tested alpha3 DSP.

  notes: >-
    Uses ComputerCard 0.4.0 with per-sample audio processing. No USB MIDI or web
    editor. Listening perspective is selected at boot and is not saved to flash.
    Both pulse inputs use held gate levels, with a minimum reliable duration of 2 ms.
