Preparing samples for the Multigrain

The Intellijel Multigrain wants one format and holds you to it: 16-bit, 48 kHz stereo WAV. Anything else loads wrong or not at all. Projects live in numbered folders, 01 through 48, each holding up to 128 samples, with a shared Global Wavs folder reachable from every project.

The limit to watch is length. The Multigrain truncates anything past about 32 seconds on import, so trim long files first rather than letting the module cut them. SampleStack converts to 16-bit 48 kHz stereo, flags samples over the 32-second limit before they are copied, and writes them into the project folder layout the module expects. The Multigrain sample management guide covers the full workflow.

Frequently Asked Questions

What sample format does the Multigrain need?

The Multigrain plays 16-bit, 48 kHz stereo WAV files. Mono files need to be converted to stereo before loading. There's a 32-second soft limit per sample, and longer files are truncated on import.

How are samples organized on the Multigrain?

The microSD card uses 48 numbered project folders (Project01 through Project48), each holding up to 128 samples. There's also a global Wavs/ folder shared across all projects, and a Recs/ folder for module recordings (up to 1,024 files).

How is the Multigrain different from the Morphagene?

Both are sample-based Eurorack modules with different design ideas. The Morphagene is a tape and microsound module focused on splice-based navigation across long reels. The Multigrain is a granular synthesizer with per-project sample sets, oriented toward texture synthesis from many short samples rather than splice navigation across long ones.

Can I prepare Multigrain projects on a Mac?

Yes. SampleStack includes a Multigrain profile that handles the 48 kHz stereo conversion, validates the 32-second length limit, and organizes files into the correct project folder structure on the SD card.
