Drift is an AudioUnit effect plugin for creating chaotic modulation. It is based on a two-dimensional fractal generator commonly used for airflow modeling but applied here onto output level and filter cutoff, giving them organic, random but smooth motion. Combined with a simple, high-contrast interface, Drift easily makes any static sound come to life.
Drift works with Logic, GarageBand, Live, Maschine, Studio One, ReNoise, Reaper, Bidule and other Mac software that supports AudioUnit instrument plugins. It requires OS X Leopard, Snow Leopard or Lion.
