Hybrid subtractive / FM synthesizer with 3-layer granular texture FX, paired with the GammaWaveFX insert effect plugin. Built in C++ with the Hearth saturation engine (Heat, Sparks, Weight + 7 Orbit modes), Formant, Ladder, Throat & Plasma filter engines, MTS-ESP / Scala / MPE microtonality, and 300+ factory presets.
2 oscillators + dedicated Sub + Noise. 9 shapes including Harmonic, Bit-Sine, PD-Reso and Var-Triangle, up to 5-voice unison per oscillator, per-oscillator analog Drift, OSC2→OSC1 FM and Ring Mod.
A resonant SVF (LP / HP / BP) into a character engine — Formant (vowel morph), Comb+, Ladder (4-pole, 2× oversampled), Resonator bank, Throat (vocal-tract waveguide) or Plasma (granular vowel) — plus a dedicated high-pass filter.
Hearth chains Heat, Sparks and Weight saturation stages into an Orbit stage with 7 modes — Inertia, Gravity, Singularity, Photosphere, Flux, Bitcrush and Fold. Per-oscillator Drift adds analog pitch instability so no two notes sound sterile.
Three parallel grain layers, each with Size, Rate, Pitch Randomisation, Position Jitter and Mix, with random per-grain stereo placement — on your synth voice or, in GammaWaveFX, on external audio.
A dedicated Filter LFO plus 5 assignable Mod LFOs (10 shapes incl. S&H, Noise, Sine³ and exponential saws), Lorenz Chaos, Amp / Filter / Pitch envelopes with curve tension, velocity, mod wheel, key tracking and 3 Macros — all routable through an 8-slot Mod Matrix.
A re-orderable 9-effect master rack — Bitcrush, Tempo-Sync Delay, Ping-Pong Delay, Reverb, Chorus, Phaser, Flanger, Compressor and 3-Band EQ — followed by Pump and a final safety Limiter. Also includes the free GammaWaveFX insert-effect beta.
Bring the GammaWave look and attitude to pocket hardware. Pocket GammaWave (GW-1) is a free, open-source replacement firmware for the M-VAVE FM-1 (dual-core JieLi AC791N) plus a browser Web Studio — with a GammaWave-style HUD (Hearth sun, audio-reactive spectrum + filter curve, Wraith ribbon), 8 synth engines (analog, 6-op FM, phase distortion, lo-fi / bytebeat, voice, organ, noise, drums) and a 49-genre song generator including Trap ATL, UK Drill, Dark Trap & Rage Trap.
A new instrument built on the GammaWave engine for rage, trap and dark melodic leads. One CHARACTER morph sweeps a single voice from flute to whistle, singer, choir, bell and scream; RAGE decides how hard it fights back. Sung vowels through a real vocal tract, a throat that goes from baby voice to demon, breath and effort you can play, syllables on every note, a physical-model flute you blow with the mod wheel — and the folds, growls and crunch to tear all of it apart.
