Perform Live MMM includes a dedicated Performance Skin designed for low-light and stage environments.

The synth engine was developed from the ground up to facilitate sounds ranging from pristine modern FM sounds to crunchy bit-crushed mayhem - with everything in between. It is equipped with 6 highly specialized macro controls that makes it easy to set up without any tedious programming. Features: - 3 operator FM synth engine with up to 8 voices - Macro controls over FM amount, harmonicity, phase and bit resolution (labeled "redux"), attack, combined decay/release and sustain - LFO with shape control (sine, triangle, ramp up, ramp down, square, random) and user-definable destination - Drive control KNOWN ISSUES: As of right now the standalone app does not support incoming Midi.
