SingleGrain in Action


Features

Preset Library

Ships with 80+ factory presets spanning pads, textures, percussion, and sound design categories. Browser-searchable and fully editable.

Real-time Processing

Ultra-low latency grain playback designed for live performance. Feed any input signal and granularize it on the fly.

Modulation Matrix

Route LFOs, envelopes, and MIDI CC to any parameter. Create evolving, breathing sounds with built-in randomization.

Time Stretching

Stretch audio to extremes without pitch artifacts. From subtle thickening to alien atmospheres, bend time exactly how you want.

Improved Sample Reverse

SingleGrain includes several unique settings purpose-built for reverse playback — from fixed grain positioning to synced boundary behavior — giving you precise, musical control over reversed audio.

Granular Engine

Load any audio file and slice it into thousands of micro-grains. Control density, size, pitch, and scatter independently for infinite variation.

Plugin Guide

Global & File Management

1Init — Resets the current patch to default settings.
2Save — Saves the current patch as a preset for future use.
3Load — Opens the file explorer to load an existing preset.
4Next Preset — Quickly cycles to the next available preset in the folder.
5Name — Displays the name of the currently loaded preset.
6Main — Switches the plugin interface to the main synthesis view.
7Matrix — Opens the automation matrix view to manage complex modulations.

Grain & Playback Controls

8Length — Controls the end position (right boundary) for the grain when unsynced.
9Attack — Adjusts the fade-in time when a grain is triggered or retriggered.
10Decay — Adjusts the fade-out time when a grain is triggered or retriggered.
11Position — Controls the start position (left boundary) for the grain.
12Speed — Manages the playback speed of the sample.
13Pitch — Shifts all frequencies after speed effects have been applied.
14Amp — Controls the overall output volume of the plugin.
15Small Knob — Controls automation depth. Drag an LFO onto a knob to assign it. Drag a non-focused LFO to automate the depth of the primary LFO.
16Load (Sample) — Opens the explorer to import a new audio sample.
17Arrow (Prev/Next) — Quickly cycles through samples in the current folder.
18Sample Name — Displays the name of the currently active audio file.
19Trim — Crops the current sample to fit within the designated play area boundaries.
20Norm — Normalizes the amplitude of the current sample to maximize volume without clipping.
21Mono — Restricts playback to one grain at a time; new notes will cut off the previous grain.
22Sync (Length) — Toggle between Unsynced (retriggering only occurs outside boundaries) and Synced (standard playback with specific behavior for negative speeds).
23Triplet — Switches the timing for synced playback to triplet divisions.
24Lock Pos — Off: grain starts at the end of the previous grain when speed is negative. On: grain start is fixed to the designated position even when speed is negative.

Modulation & LFOs

25LFO Select — Choose which of the available LFOs is currently active for editing.
26Off (LFO Mode) — LFO repeats indefinitely and ignores note-on triggers.
27Env (LFO Mode) — LFO acts as an envelope; it restarts at note-on and does not repeat.
28Sync (LFO Mode) — LFO restarts at note-on and continues to repeat.
29LFO Shape Select — Selection tool for the LFO waveform shape.
30Save (LFO) — Saves the custom-drawn LFO shape.
31Load (LFO) — Loads a previously saved LFO shape file.
32LFO Rate/Division — Sets the speed/rate of the LFO.
33Red Dot — Defines the starting position for the LFO (the end position is mirrored).
34Yellow Dot — Click and drag to adjust the curvature (slope) of the LFO segment.
35Pink Dot — Double-click to create a new point; right-click to delete an existing point.
36Sync (LFO Rate) — Synchronizes the LFO rate to the host project's BPM.
37Triplet (LFO) — Switches the LFO or Sync divisions to triplet timing.

Output & Performance

38Gain — Allows you to increase or decrease the master gain.
39M1 (Macros) — A master control knob that allows you to manipulate multiple parameters simultaneously.
