Preparing Samples for Eurorack Samplers

Eurorack sampler modules open up a world of creative possibilities in modular synthesis. But getting your samples into the right format can be frustrating. This guide covers what you need to know about preparing WAV files for Eurorack samplers.

Why Eurorack Samplers Need Mono

Most Eurorack sampler modules have a single audio output per voice. This is by design — in a modular system, you route audio through patch cables to mixers, effects, and other modules. A single mono output per voice gives you the most flexibility in your patches. Because of this, these modules expect mono WAV files.

Sample Preparation Workflow

Here is a typical workflow for preparing samples for Eurorack modules:

1. Collect your source samples (from sample packs, recordings, or synthesizers)
2. Convert stereo files to mono using It's mono, yo!
3. Trim silence from the start and end of samples
4. Normalize volume levels for consistency
5. Rename files with short, descriptive names
6. Copy to your SD card and test on your module

Batch Converting for Large Libraries

If you have a large sample library to prepare, batch conversion saves a lot of time. It's mono, yo! lets you convert unlimited files at once with real-time progress tracking. Just drag your files in, select the output folder, and the app handles the rest.
