GR-7 Grain Delay manual
A granular effect that cuts any sound into grains and replays them in time with your song. GR-7 Grain Delay records the last four seconds of whatever plays through it and reads that recording back as grains from 5 ms to 1 s long, up to 16 in each burst. Bursts start on your song’s grid or up to 200 times a second, any grain can be moved up to two octaves onto notes you pick or played backwards, and Freeze stops the recording so the grains keep reading the same four seconds.

The four knobs
The four knobs on GR-7 Grain Delay’s screen shape the whole sound, and each preset sets where they start.
- Hold
- Stretches each piece longer and slower until the cloud hangs in the air.
- Stack
- Spreads the pieces wider and sends more of them up or down an octave, and on presets that run free of your song’s grid it starts them more often.
- Drift
- Sets the cloud swaying in time with your song, and loosens where each piece lands on the grid or, on presets that run free of it, picks pieces from further back in what you played.
- Air
- Brightens the top and gives the cloud more chorus and a bigger plate reverb.
Your DAW records every turn as automation, and Undo takes a turn back.
Using presets
Click the preset’s name at the top to see them all, or use the arrows beside it to go to the next or the one before. Its folders are down the side, with Favorites and My presets under them, and the star beside a preset keeps it in Favorites.
Save as new keeps the sound you have under a name of your own in My presets, and Save updates one of yours. Point at one of yours to rename or delete it.
Write 4 more like this writes four new presets close to the one you’re on and places them around it on the map beside the list. Drag the dot between them to blend, and Keep this sound saves the blend as a preset of your own. It works with Pro and on a plugin you bought.

More controls
More controls at the top opens the settings GR-7 Grain Delay’s face has no room for. Press it again to go back.
Grains moved up to two octaves, held to octaves, fifths, chords or a scale, with any share of them played backwards. Freeze stops the recording, so the grains keep reading the same four seconds for as long as it is on. A filter, a chorus, an echo, a plate reverb and a compressor after the grains.
- Live Grain
- Replays the last four seconds as a cloud of tiny grains, scattered into a wash, pitched up into a shimmer or frozen.
- Curve LFO
- Moves other controls up and down in a shape you draw, slow for drifts or in time for pumps and gates.
- Filter
- Runs the whole sound through one filter in ten types, with resonance and drive.
- Studio 56 Chorus
- Widens and thickens a sound with a slow shimmer that keeps the bass solid, from a gentle double to a ringing jet.
- Filtered Stereo Delay
- Echoes from 0.3 ms to 12 seconds or a note of the song, in parallel, ping-pong, crossed or as two mono lines, with a filter in the feedback loop and a ducker that turns the echoes down while the sound plays.
- Plate Reverb
- Adds a smooth plate reverb, from a short ambience behind drums to a long bright or dark wash behind pads.
- VCA Compressor
- Compresses from a threshold of -60 to 0 dB at 1:1 to 20:1, with a knee of up to 24 dB, an attack from 0.05 ms and an RMS or a peak detector, hearing the sound itself or a second input.
