On a compatible Apple silicon Mac, select an audio region and use Processing → Stem Splitter. Choose the parts you need, then audition them against the original. Estimated stems are not the original production tracks.
Logic Pro's Stem Splitter estimates vocal and instrument parts from an audio region and creates separate regions in the project. On a compatible Mac, Control-click the audio region in the Tracks area, choose Processing → Stem Splitter, and select a preset or custom combination. Listen to the results before using them in a mix or practice track.
Apple's current Logic Pro Stem Splitter guide lists vocals, drums, bass, guitar, piano and other instrumental parts. Presets determine which parts are extracted separately and which are grouped. The tool is available on Macs with an M1 or later Apple silicon processor; features and menus can vary with the installed version.
Split a song into parts in Logic Pro
- Start with a usable source. Import a recording you have permission to use into a Logic Pro project. Keep the original region available so you can compare the same verse and busy chorus after processing.
- Select the audio region. In the Tracks area, Control-click the region and choose Processing → Stem Splitter. The action is on an audio region, not a general mixer command.
- Choose the parts. In the Stem Splitter window, select a preset or create the combination you need. Read the preset labels: a grouped submix is not the same as separate files for each part.
- Run the split and audition. Review the created regions individually and in context. Check vocal consonants, drum attacks, bass notes and sustained instrument tails against the original; overlapping sources can leave bleed or change wanted detail.
- Prepare the result for its destination. Keep the regions aligned when editing. If you need standalone files for a collaborator, use Logic's audio export options and verify the saved files; regions inside a project are not by themselves a delivery package.
Why is Stem Splitter missing?
Apple says the feature is unavailable on Intel-based Macs and when Logic Pro runs in Rosetta on an Apple silicon Mac. See Apple's feature-availability guidance. Also verify that you are using a Logic Pro version that includes the feature and that an audio region is selected.
If your Mac has Apple silicon and you intentionally enabled Rosetta, check whether a project plug-in requires it before changing anything. Apple's Rosetta instructions describe quitting Logic, opening Get Info for the app, deselecting Open using Rosetta, and reopening Logic. Recheck any plug-ins or devices that depended on the previous setup; switching modes does not make an Intel Mac compatible.
Logic Pro and Saturalabs: choose the workflow you need
| Need | Logic Pro Stem Splitter | Saturalabs |
|---|---|---|
| Several named music parts | Use a preset or custom combination of supported stems on a compatible device. | Describe one source per pass; each pass returns the target and remaining mix. |
| Edit directly in the project | Review created audio regions in Logic. | Download the selected WAV and import it into your editor. |
| A specific audible sound | Check whether the available stem categories fit the source. | Try a text description of one audible source and assess the result. |
| Download and limits | Check your Logic version and Apple hardware compatibility. | Uploads support MP3, WAV, MP4 and MOV up to 50 MiB; AI downloads require an account and sufficient credits. |
For the Saturalabs route, open the stem splitter, upload the original mix and describe a source such as “the acoustic drum kit.” Review Isolated sound for the target or Background audio for a reduced backing. Start each additional request from the original; separate passes do not guarantee a complete set that reconstructs the mix exactly.
Check and share your stems
A stem extracted from a finished mix is an estimate, not an export of the producer's original tracks. Check for other instruments in the target, missing notes and altered reverb. If the session or authorized original stems are available, use those when precise production control matters.
Before sharing, agree on file format, sample rate, common start point, processing and tails. Import the exported files into a fresh session and compare them with the reference. The stem delivery checklist explains those checks. For another editor, see the FL Studio stem separation guide. Separation does not grant permission to publish or remix a recording.
Can I remove vocals for practice?
Choose a suitable instrumental combination in Logic and listen across the arrangement for leftover singing and missing instruments. In Saturalabs, target the singing and review Background audio. Neither method guarantees a perfectly clean backing; the karaoke guide covers practical listening checks.
