Waves OneKnob Pumper is a plugin designed to quickly create a pumping (or rhythmic ducking) effect synchronized to the tempo, widely used in EDM, pop, and electronic music. It serves both to make a mix "breathe" rhythmically and to add a modern pulse to static sources. You can use it on pads, basses, keyboards, guitar power chords, drums, or on effects buses to give a sense of movement and enhance the beat's impact.
Unlike traditional setups requiring a sidechain compressor, a trigger signal, and routing, OneKnob Pumper offers a direct approach: no sidechain is needed. You select a pumping pattern and the ducking effect is applied immediately, speeding up production and facilitating creative experimentation, even in dense sessions.
The plugin provides 10 pumping/ducking rhythms covering fast subdivisions (up to 1/32 notes) and longer durations (up to bars). To avoid the "already heard" effect or to build more complex grooves, OneKnob Pumper also offers 3 timing offsets: ideal for placing the dip on a different part of the beat and creating counter-rhythms that animate the track.
The "OneKnob" concept translates into a single control that allows you to adjust the effect's intensity. At high intensity, you get the typical EDM pumping that makes instruments breathe with the kick drum's rhythm. At low intensity, the effect becomes a more discreet sound design tool, perfect for adding a light pulse to pads, atmospheres, synths, or reverb and delay returns, without overpowering the mix.
