Name: Dub Warning
short-description: Playable dub warning siren with PT2399-style delay.
summary: |
  A small, immediate dub warning siren for the Workshop Computer. Main sets the base
  pitch, X drives the sweep, CV In 2 colors the oscillator, and Y opens up the
  PT2399-style delay. Use Z Down for a compact Wheel Up one-shot gesture,
  Pulse In 1 for a gated siren, or Pulse In 2 for reset plucks and fast-trigger
  textures. Audio In 2 can override the Main pitch knob when patched.
