01Overview

OneKnob Pumper is built around the classic EDM pumping effect, where a sound ducks in time with the beat. Waves designed it to remove the usual setup work: you choose a rhythm, turn the knob, and the ducking starts. The plugin offers 10 rhythms, from 1/32 notes up to bar-length patterns, plus three rhythmic timing offsets for counter-rhythms. You can push it to a strong, obvious pump or dial it back to add a subtle pulse to a track.

03In depth

Sound and Rhythm Control

OneKnob Pumper applies a ducking effect that follows a rhythm you select from 10 options, ranging from fast 1/32-note patterns to slower patterns spanning whole bars. Because the ducking is created inside the plugin, you do not need to route a sidechain signal from another track.

The three rhythmic timing offsets let you shift the pattern against the beat, which is useful for building counter-rhythms or a more syncopated feel. The single control keeps the effect easy to adjust while you work on the arrangement.

Using It Subtly or Aggressively

The classic use is a full, hypnotic pump on a whole mix or a group of tracks, which is the sound most associated with EDM. Waves also highlights a lighter approach: turning the effect down to add motion and emotion to a beat.

The developer notes that the plugin can add rhythmic intensity to guitar power chords. Pads, bass, keyboards, effects buses and drums are other sources it is aimed at, so it can be placed on individual tracks or on a bus depending on how much of the mix should move.
