Built for Sound Designers, Industrial & Film/Game Composers

01 // 2 Oscillators + Sub + Noise

Subtractive, FM & Ring Mod

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.

02 // Filter + Character Engines

Resonant SVF & Character Engines

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.

03 // Hearth: 3 Stages + Orbit

Warmth That Breathes & Fractures

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.

04 // 3-Layer Granular FX

3 Parallel Grain Layers

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.

05 // Filter LFO + 5 Mod LFOs + 8-Slot Matrix

Lorenz Chaos, LFOs & Envelopes

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.

06 // 9-Effect Rack + GammaWaveFX

Full Master Chain + Free Insert FX Plugin

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.
