Standard
Vocals, bass, drums, other
4 stems
A versatile four-way split: vocals, bass, drums, and everything else combined. Great for remixes, karaoke-style instrumentals, and quick arrangement breakdowns.
Split your track into separate stems
Three AI models — 4, 2, or 6 stems. You choose when creating a project; that decides how the track is split and how detailed your stem editing and export can be.
Best instrumental and vocals
Vocals, instrumental
2 stems
Two stems: isolated vocals and a full instrumental backing track. Ideal when you need a clean minus or a vocal line without splitting the band into individual instruments.

Model comparison
Stem count, approximate separation quality (SDR), and plan availability.
| Model | Stems | Avg. SDR (dB)* | Availability |
|---|---|---|---|
| Vocals, bass, drums, other | 4 stems | ~9.2 | All plans |
| Vocals, instrumental | 2 stems | ~13.3 | Pro plan |
| Vocals, bass, guitar, drums, piano, other | 6 stems | ~10.9 | Pro plan |
* SDR (Signal-to-Distortion Ratio) indicates how clean the separated signal is relative to distortion and artifacts; higher decibel values mean better separation. The numbers are approximate averages and can vary a lot from track to track.

FAQ
They output different numbers and types of stems: four classic parts, two (vocals vs instrumental), or six with separate guitar and piano. Pick based on whether you want a fast minus, a simple band split, or fine-grained control.
Advanced models need more compute. The free and Lite plans include the standard four-stem model; Pro unlocks the full set.
Each model fits a different job. The two-stem model is often best for clean backing tracks; six stems help when you need guitar or keys on their own. Source audio quality always affects the result.
