GRFX is a powerful and creative granular effects processor that turns ordinary audio into extraordinary sonic landscapes. Slice your sound into grains and reshape them into evolving textures, shimmering chords, rhythmic glitches, haunting drones, and more. At the heart of GRFX is the Harmonic Triangle – an intuitive 3-way pitch controller that lets you morph simple tones into lush pads, arpeggiated patterns, or abstract gestures. Whether you’re aiming for organic soundscapes or synchronized stutters, GRFX gives you precise control over the flow of grains and modulation. Build complexity with four self-modulating LFOs, a multi-effect chain with probabilistic routing, and an elegant drag-and-drop modulation system. Shape your sound, modulate nearly every parameter, and sculpt immersive audio transformations in real time. Key Features: - Granular engine for creating textures, rhythms, chords, glitches, drones, ambiences, and more - Harmonic Triangle for 3-way pitch control, detuning, and microtonality - Built-in Chord Selector with 32 triads for instant harmonic richness - Grain envelope shaping for plucky, smooth, or abrupt grains - Buffer size, division, sync, and freeze controls - Rhythmic synchronization for tempo-synced effects and patterns - 4 LFOs with self-modulation and drag-and-drop assignment - Modulation panel & view mode for streamlined modulation management - 2 Multi-Effect slots (Filter, Distortion, Delay, Peak EQ, Chorus, Phaser, Bitcrusher, Reverb) with probability-based routing - Dedicated Send FX with Delay and Reverb in series or parallel mode - Flexible mixer section for sculpting wet/dry balance and routing AUv3 Audio Unit plugin – requires an AUv3-compatible host app such as Logic Pro, GarageBand, AUM, or Cubasis.
