Phase Mutant: FM Distortion Effect Plugin by BLEASS Free Download

Phase Mutant offers three algorithms: Oscillator Modulates Input, Input Modulates Oscillator, and Input Modulates Itself. Each routes the frequency modulation differently, so the same input can produce very different textures.

The oscillator's waveform can be morphed smoothly from sine through triangle and sawtooth to square. Intensity sets the maximum modulation amplitude, Amount sets the modulation strength within that range, and a low-pass Cutoff shapes the processed signal. Dry/Wet controls the balance with the unprocessed input.

The oscillator follows the pitch of the input in real time. Tracking Channel selects left, right or the sum of both channels for analysis. Smooth sets how quickly the tracker moves between pitches: very fast settings follow closely, 10 to 30 ms smooths short-term variation, and settings above 100 ms create slurring, portamento-style effects.

Ratio multiplies the detected pitch from 1:8 to 8:1, which covers three octaves in each direction, and Fine adds up to one octave of adjustment.

Phase Mutant includes an envelope triggered by transients in the input, two LFOs with six waveforms that can sync to the beat or run free, and a step sequencer for rhythmic, stepped modulation. Each source can control up to two target parameters, which makes the plugin useful for movement as well as static distortion.

The Oscillator Modulates Input and Input Modulates Itself algorithms use look-ahead, which adds a small latency. The DAW compensates for it on recorded parts, but the delay can be noticeable on live input.
