Quota StemsFree local stem separation

Quota Stems is a free stem-separation tool for macOS and Windows that runs locally without an account. It can split a song into up to six primary stems, including vocals, drums, bass, piano, guitar, and other, then subdivide the drum track into kick, snare, toms, hi-hat, ride, and crash. With 6-way drum separation enabled, a song can produce 12 independent audio files. The app also creates a 32-bit float residual file for rebuilding the original drum bus, and can export WAV, MP4 stem videos, or Ableton Live 12 projects. A roughly 440MB model download is required the first time 6-way drum separation runs.

Quota Stems is a free vocal and stem-separation tool for macOS and Windows. It processes audio locally, requires no account, and is designed to turn a song into editable parts such as vocals, drums, bass, piano, and guitar.

Up to 12 stem files

The standard model produces four stems: vocals, drums, bass, and other. Its Advanced model adds piano and guitar for a total of six. Users can then apply 6-way drum separation to split the drum stem into kick, snare, toms, hi-hat, ride, and crash.

Quota Stems also creates a 32-bit float residual file. The residual represents the drum bus minus the combined separated drum parts, so the six components and the residual can be combined to reconstruct the original drum stem without changing its mix. The product describes this as a drum bus that can be rebuilt.

Local processing and Ableton export

The product says that separation happens entirely on the device: “No account, nothing phones home.” For music producers, one of the more practical export options is an Ableton Live 12 project containing the separated tracks. The app can also split material into scenes by song section or keep each stem as a single raw clip.

Quota Stems supports input from files or URLs and can export WAV files, MP4 stem videos, and Ableton Live projects. The official site also lists Force and MPC compatibility, although it does not specify those export formats in the FAQ.

Model download and availability

Six-way drum separation uses the MDX23C DrumSep model. Its weights are not bundled with the application, so the first run requires an internet connection to download a checkpoint of about 440MB.

Quota Stems is available for macOS and Windows under a “Free forever, no account required” model. Its combination of local processing and direct Ableton project generation makes it particularly relevant to producers who want separated material ready for further mixing.

Frequently Asked Questions

How can users split a drum stem into kick, snare, and hi-hat?

Run the song in Quota Stems and set Drum Split to 6-way. The app will produce separate files for kick, snare, toms, hi-hat, ride, and crash. The 4-way mode outputs kick, snare, toms, and cymbals instead.

Can Quota Stems output more than four stems?

Yes. The standard model outputs vocals, drums, bass, and other. The Advanced model adds piano and guitar, bringing the total to six primary stems. With 6-way drum separation enabled as well, one song can produce 12 files.

Can the separated drum parts be rebuilt into the original drum bus?

Yes. Keep the 32-bit float residual file generated by Quota Stems, then combine it with the six separated drum parts. Together, they can reconstruct the original drum stem without changing its mix.

How can users import separated stems into Ableton Live?

In Options, choose the Ableton Session preset and run the song. Quota Stems will generate an Ableton Live 12 project containing the separated tracks. Users can also add cue-point scenes as part of the export.
