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. Standalone version included.
Fauve
This audio processor captures and reinterprets sonic fragments, introducing intentional glitches, distortions, and variations. It allows users to reshape sounds, creating unique soundscapes that blend memory and reality.
- Records and breaks down incoming audio into fragments
- Introduces intentional glitches, distortions, and memory errors
- Allows shaping playback with sampling/slicing parameters
- Sculpts amplitude through 'Absence' parameter
- Blurs reality with 'Mirage' parameter for dream-like effects
- Lock parameters to preserve settings while browsing presets
- In-GUI information for parameter details

Fauve is an audio processor that collects sonic fragments and replays them, not always faithfully. It forgets, distorts, and glitches into new meanings. Like the hallucination of a broken machine. A fractured memory, yours to reshape. "Fauve is a perfect cure for sound-alike effects. It really is distinct from other buffer/glitch and granular tools. And it strikes an ideal balance between predictability and weirdness, between polished controls you can learn and master and unexpected combinations that surprise you." Peter Kirn – CDM By continuously recording incoming audio, Fauve analyzes and breaks sound into small units we call collections. When playing them back, it sometimes fails, opening space for the user to edit and shape the material according to their own sonic vision. Fauve can be a harsh distortion, a gentle shadow, a paroxysmal dance between reality and dream, and much more. It can slightly scramble your sound, completely strip it of its original meaning, or introduce subtle, almost imperceptible variations to make it richer, yet always organic. Fauve disrupts, but never destroys. REMEMBER / FORGET Fauve listens and remembers — but it may forget to capture the present, getting stuck in the past. It blends memory and reality, shaping a soundscape as if it were truly what it just heard. BEHOLD THE HALLUCINATION Beyond the native errors of its faulty replicatory nature, Fauve opens space for your design: you can shape the playback of fragments using classic sampling/slicing parameters like Disorder, Repeat, Freeze, and playhead rate. SHAPING THROUGH ABSENCE Sculpts amplitude in two distinct ways through Absence: turn left to assign a random value to each fragment for more organic results, or turn right to introduce audio drops, adding uncertainty, or even reaching distortion wilderness on shorter fragments. BEYOND BALANCE: ENTER THE MIRAGE Let Fauve blur reality with its dream using the Mirage parameter. Shape the balance, focus it across the stereo field, and control amplitude for both source and processed sound. LOCK PARAMETERS Enable lock toggle to preserve key parameters values while browsing presets. IN-GUI INFOS Enable Infos toggle to get all parameters details always in sight; just hover on a parameter. Fauve is a totem/series plugin, and like all totems, it follows its own logic. Timing in Fauve doesn’t rely on beats or note values — it’s driven by the material itself. Every operation is triggered by zero crossings, making the outcome deeply dependent on the source. Same settings, radically different results.
