GranSample as an AUv3 Plugin

GranSample ships as an Audio Unit v3 instrument, so the same engine you use standalone can run as a track in your DAW. Load it once and you get the full 4×4 grid, your Kits, the granular engine, effects, and the sequencer — all hosted inside the project.

Loading the plugin

GranSample registers as an AU Instrument (an aumu audio unit), not an effect. In your host’s plugin browser, look for it under instruments — the display name is:

Digilog: GranSample

Add it to an instrument or software-instrument track. It has been verified in GarageBand, Logic, AUM, Drambo, and Loopy Pro, and works in any host that loads AUv3 instruments. The plugin window shows the same pads, Kits, and Sample Editor you know from the standalone app, so most of the rest of this manual applies unchanged — see The Pad Grid and Library & Projects to get oriented.

Host transport sync

When GranSample runs as a plugin, the step sequencer follows the host’s transport instead of running its own clock. Press play in your DAW and any pattern you’ve programmed plays back locked to host tempo and position; stop the transport and the sequencer stops with it.

MIDI through the host

MIDI is routed by the host. Notes coming into the GranSample track — from a keyboard, a piano roll, or another plugin — trigger pads through the host’s MIDI input. GranSample also emits MIDI out for pad taps, so you can record what you play on the grid back into your DAW.

This means MIDI Learn and the in-app Bluetooth/USB browser are standalone features; inside a host you patch MIDI with the host’s own routing. For note mapping and Chromatic Mode, see MIDI Setup & Control.

Parameter automation

GranSample exposes its controls to the host as automatable parameters, organized into a tidy hierarchy in your DAW’s automation lane picker: a Master group first, then a Sequencer group, then Pad 1–Pad 16, each containing its own per-pad controls. The tree covers master level and filter cutoff, every per-pad slider, the granular and modulation routings, and a per-pad effects mix (wet) level — 628 parameters in total.

Draw automation on any of them the same way you would for any plugin: ride a grain Position, sweep the master Filter cutoff, or modulate a pad’s effects mix across a section. The granular parameters, modulation matrix, and effects pages describe what each control does.

State saved in the project

GranSample stores its full state inside the host project. The loaded Kit, your pad settings and sliders, the sequencer pattern, and the selected scene are all written into the plugin’s saved state, so reopening the project restores exactly what you had — no need to reload a Kit by hand.

Pro gates are the same

The free / Pro split is identical to standalone. Pads 1–4 play with the full engine in any host; pads 5–16 require GranSample Pro. The modulation matrix, Sample Chop, .gskit export, and master audio export are Pro features in the plugin too.

Pro unlocks once across the whole app: buy it in the standalone app and the entitlement is shared with the plugin, so locked pads and Pro features unlock inside your host without a separate purchase.
