What OneKnob Pumper does
Pumping, a rhythmic volume dip often used in electronic dance music, usually depends on a sidechain setup that can be complicated to route. OneKnob Pumper creates the ducking itself, so no sidechain routing is needed. The rhythm is chosen from ten pumping and ducking patterns, with note values starting at 1/32 notes and extending to whole bars, and the single knob sets how deep the effect goes.
The plugin also offers three rhythmic timing offsets for counter-rhythms, which shift the pattern against the beat. Dialed back, the knob adds subtle motion to a beat; turned further, it produces the stronger rhythmic intensity suited to guitar power chords. The developer notes that the knob does not travel fully to its maximum position.
Key features
- Ten pumping rhythms. Ten different pumping and ducking rhythms are available, with note values from 1/32 notes up to bars, so the pattern can follow the tempo of the material.
- No sidechaining needed. The ducking is created inside the plugin, so the track does not have to be routed to a separate sidechain input to produce the effect.
- Three timing offsets. Three rhythmic timing offsets shift the pumping against the beat, producing counter-rhythms that differ from the straight pattern.
- Single intensity knob. One knob sets the amount of the effect, from a subtle addition of motion to a more aggressive rhythmic intensity, and it does not reach its full travel.
- Rhythm and knob workflow. The intended workflow is to choose a rhythm, turn the knob and start the pumping, with no further setup required.
