ALS Export¶
The --export-als flag generates an Ableton Live Set (.als file) from your processed stems.
How it works¶
- Copies the template — uses the bundled
Example.alstemplate (or specify a custom one with--als-template) - Sets project tempo — writes the detected BPM into the Live Set
- Matches stems to tracks — maps processed stems to template tracks by type (Drums, Bass, Vocals, etc.)
- Injects AudioClips — places unwarped audio clips into arrangement view
- Mutes the full mix — the reference track is included but muted so it doesn't double the audio
Template tracks¶
The bundled template has pre-configured tracks:
| Track | Stem type |
|---|---|
| Drums | Drums |
| Percussion | Percussion |
| Bass | Bass |
| Synth | Synth |
| Vocals | Vocals |
| Backing Vocals | Backing Vocals |
| FX | FX |
| Sample | Sample |
| MIDI tracks | For cleaned MIDI files |
Usage¶
During processing¶
From already-processed output¶
With a custom template¶
Output¶
The generated .als file is written to the processed/ directory. Open it directly in Ableton Live.
Experimental
ALS export is experimental. The generated Live Set should work out of the box, but complex template customizations may require manual adjustment in Ableton.
