Mix & export

Separated tracks

The standard HTDemucs model separates vocals, drums, bass, and other sounds. An experimental ONNX mode also estimates guitar and piano. These tracks can contain bleed, especially piano. Results vary by song.

Mix & production

• Edit clips and adjust track levels.
• Find the production tools in the application.
• Grid-snapped punch: in/out points snap to the grid; user audio clips have native startMs.
• Instrumental part from Production:
  • tempo / key / style via YuE2 (bass, drums, accompaniment);
  • mix / stems via the opt-in ACE-Step 1.5 Base Lego sidecar (Python REST, not the Turbo GGUF). YuE2 does not accept audio_input. Lego may return a fused mix, not a dry stem. A YuE2 mix stays CC BY-NC. Lego install: Setup.

Export

Export your mix as WAV, FLAC, or MP3. If Song Maker cannot find ffmpeg, set its path with SONG_MAKER_FFMPEG.
