Phase Monkey is a polyphonic synthesizer inspired by the classic phase distortion synthesizers of the mid-1980s. However, instead of being a direct copy, Phase Monkey presents a fresh take on the classic sound engine, including the rare eight-stage envelopes. The result is a surprisingly versatile digital instrument that can produce anything from warm pads to shimmering leads to snarling basses. Whatever you do, don’t have fun with it!
