GRN

GRN captures incoming audio and lets you pull grains from anywhere in its history. Not just frozen moments — you choose how far back to reach, how wide to scatter, and how chaotic it gets. The result: textures that evolve, shift, and surprise you.

Grain Control:

• Size 10-500ms, Density 0.5-100/sec (tempo-syncable).
• Playhead Position with adjustable zone width.
• Buffer Size — Short, Medium, or Long.
• Spray — scatter within selected zone.
• Freeze — lock buffer, replay indefinitely. Freeze Hold keeps audio playing when DAW transport stops.
• Gate — threshold-based grain triggering.

Pitch & Harmony:

• Pitch shift ±24 semitones.
• Pitch jitter up to ±12 semitones.
• Harmony Mode — Octaves, Fifths, Oct+5th. Scatter knob controls how many grains receive harmony intervals; Direction knob steers pitch up, down, or both.
• Scale Quantization — Major, Minor, Pentatonic, Chromatic, Dorian, Phrygian, Lydian, Mixolydian, Harmonic Minor, Whole Tone.
• Reverse playback.

FX Rack:

• 9 built-in effects — Bitcrusher, Chorus, Reverb, Delay, Phaser, Flanger, Distortion, Tremolo, and Utility.
• Drag-to-reorder effect chain.
• Per-slot animated visualizers and bypass toggle.
• WET / DRY / BOTH routing — process the granular output, the dry signal, or both.

Dual LFO Modulation:

• 2 independent LFOs — drag from waveform onto any knob to assign.
• 7 shapes: Sine, Triangle, Square, Saw Up, Saw Down, Sample & Hold, Random.
• Tempo sync with note divisions from 1/1 to 1/32. Sync to DAW transport for phase-locked modulation.
• Bipolar depth — invert modulation direction per route.

Feedback Engine:

• Route output back through the full chain.
• Delay 10-2000ms.
• 3 saturation modes (Warm / Tube / Crunch).
• Stereo width, tape wobble.
• HP/LP filters with PRE/POST routing.

Workflow:

• 100 factory presets across 11 categories — Textures, Space, Lo-Fi, Pitch, Glitch, Rhythmic, Creative, Ambient, Dark, Cinematic, Subtle.
• Save and organize your own presets in subfolders — appear as nested menus in the browser.
• Mix Lock — keep your dry/wet balance when browsing presets.
• Randomizer — 5 musical profiles (Ambient, Shimmer, Glitch, Subtle, Deep).
• Real-time waveform and grain visualization.
• Info buttons for every control.

Good for:

• Ambient textures that never sit still.
• Tempo-synced glitch and stutter.
• Film/game sound design.
• Feedback drones and evolving pads.
• Turning drums into pitched instruments.

Specs:

• VST3 / AU / CLAP.
• Windows, macOS (Intel + Apple Silicon), Linux.
