Turn Audio on, then hold and move on the pad. Three gesture dimensions — X, Y, and drag speed — control three sound parameters: pitch, brightness, and loudness.
Natural is the obvious one-knob-per-parameter layout. Scramble deals a new random assignment — suddenly your practiced gesture means something else. Cross-couple blends gestures into every parameter at once, more like a violin bow.
Play a phrase, scramble, play it again. How long until the new mapping feels like an instrument?
