The Scrubber is a general controller for friction-induced sound. Allowing the user to engage in familiar gestures and feeling actual friction, the synthesized sound gains an evocative nature for the performer and a meaningful relationship between gesture and sound for the audience. It can control a variety of sound synthesis algorithms of which we demonstrate examples based on granular synthesis, wave-table synthesis and physically informed modeling.
