Version History
Macros + XY Pad
Four macro knobs and an XY pad in a new dockable performance panel. Drag a macro's connector dot onto any knob to link it — as many targets as you like, each with its own depth — then sweep them all with one gesture or a single DAW automation lane. The XY pad drives Macros 1 and 2 together for two-handed moves.
MIDI Pitch Mode
Play GRN as a polyphonic granular instrument: hold notes on your keyboard and the grains retune to them, with a per-note ADSR envelope, velocity response, and a sampler-style root key. Off by default — nothing changes in existing projects until you turn it on.
Stacked Modulation
A knob can now be driven by several sources at once — an LFO wobble, an envelope, and a macro can all pull on the same control, and their movements add together. Each assignment draws its own ring around the knob, so you always know which one you're grabbing.
Filter Q Modulation
HP and LP resonance can now be modulated like the cutoffs — LFO-driven resonance sweeps, envelope-pumped peaks, or a macro that sharpens the whole filter section at once.
Buffer Library
Found a texture you love? Freeze it, hit the new LIB button, and save the captured buffer under a name. Load it back in any project, any time — your best captured moments become a reusable sound library, separate from presets.
LFO PLAY Mode
The new PLAY toggle locks a synced LFO to the song position — loops stay consistent and bounces match exactly what you heard, even with the random LFO shapes. Replaces the old global LFO Retrigger setting, now per-LFO.
Modulation Depth Bars
Every LFO / envelope assignment now has its own draggable depth bar right in the target list, with a live indicator sweeping the exact range the knob is travelling — clamps and all.
14-Day Free Trial
Try the full GRN free for 14 days, started right from the plugin — no account needed, and GRN never phones home after the one-time trial start. When the trial ends, your projects still open and render exactly as you made them.
Redesigned Header
Taller top bar with the GRANULAR FX wordmark, the FRCTL logo, and the MOD / MIDI / MACRO panel toggles grouped together on the right.
macOS: GRN MIDI Audio Unit
A new GRN MIDI entry in the AU list accepts notes in Ableton Live and Logic Pro. Plain GRN stays the everyday audio effect, and existing AU projects keep loading untouched.
Included
- VST3, AU, CLAP plugins
- Windows, macOS, Linux
- 3 computer license
- Lifetime free updates
- Direct developer support
System Requirements
Questions
Can I use it live?
Yes. GRN processes audio in real-time with zero latency and low CPU usage — perfect for live performance setups.
Does it work with MIDI?
Yes. Since v3.2.0, MIDI Pitch Mode lets you play GRN as a polyphonic granular instrument — hold notes and the grains retune to them, with a per-note envelope and velocity response. It's off by default, so GRN still works as a regular audio effect: insert it on any audio track and it processes whatever passes through. All parameters are fully automatable from your DAW.
How do I install?
Download, drag to your plugins folder, enter your license key on first open. Done.
Is there a trial?
Yes. Try the full GRN free for 14 days, no card, no account. After that it keeps working in any project you already made, it just won't let you change anything until you buy it.
Is there a free version?
Yes. GRN Lite has the same core engine with fewer features. Try it free.
Commercial use?
Yes. Use in any project. Keep 100% of your royalties.
CPU heavy?
No. Optimized for real-time with 16 grain voices. Runs smooth on older systems.
What's included with my purchase?
All future updates are included free. One-time purchase, lifetime updates, no subscriptions.
