The Kaoss Pad is a touchpad effects processor for audio and musical instruments, made by Korg.

The Kaoss Pad's touchpad can be used to control its internal effects engine, which can be applied to a line-in signal or to samples recorded from the line-in. Effects types include pitch shifting, distortion, filtering, wah-wah, tremolo, flanging, delay, reverberation, auto-panning, gating, phasing, and ring modulation.
