Controls
Best uses
- Sidechain-style pumping without a kick or a sidechain route
- Trance gates and stutters on pads, chords and vocals
- Rhythmic tremolo with saw, sine or triangle shapes
- Ducking a bass under the kick on every beat
Properties
Signal chain: Input → Gain × (1 − Depth × (1 − Shape)) → One-pole Smoothing → Dry/Wet Mix → Output. The shapes are breakpoint curves over one cycle; the cycle follows the host tempo and, while the transport plays, is read from the song position so it stays locked to the grid; stopped, it free-runs at the host tempo. Half-time Pump spans two Rate notes. Stereo-linked, zero latency.
