DUB-1 turns the M-VAVE FM-1 into a generative dub techno machine. Chord stabs, tape echo, FM pings, sub bass, a ducking kick, percussion and vinyl crackle create an arrangement that develops automatically. Performance controls steer the filter, delay, energy and space, with holds, mutes, solos, breaks and fills. A browser emulator previews the same instrument before installation.
