The Kaoss Pad is, essentially, a cross between an effects unit and a budget sampler. It features 60 built‑in preset effects including filters, phasers, flangers, delays, reverbs, autopanners, ring modulators and a five‑second stereo looping sampler. The Kaoss Pad's main claim to fame (or notoriety), however, is its unusual user interface. The unit is designed to be controlled in real‑time using an illuminated, dynamic real‑time, X‑Y ribbon controller pad derived from that of Korg's high‑end Z1 physical modelling synth.
