Stooms is a stem-separation plugin with ARA 2 support. Split any song into drums, bass, vocals and everything else — then turn every stem into MIDI. Right on the clip in your DAW, all on your Mac.
VST3 with ARA 2 · file-mode VST3 · standalone app · macOS on Apple Silicon
Press Separate and Stooms splits the whole song — up to 10 minutes — into drums, bass, vocals and other, on your Mac. Cancel any time. Nothing is uploaded.
Press S to solo a stem, M to mute it. An instant instrumental, an a cappella, just the groove. Hold the waveform to hear the mix from that point.
Press Get MIDI and every stem becomes a MIDI file, on your Mac, lined up with the clip and your project’s tempo.
Bass and vocals have two modes on their Drag MIDI menu. Notes gives one clean pitch per note. Expressive keeps slides and vibrato as pitch bend (±12 semitones), from the same analysis — switching never re-runs it.
Drag a stem straight onto a track, or Drag all for four aligned 32-bit float WAVs. Save stems writes them to a folder. Drag MIDI does the same for the MIDI.
With ARA 2, Stooms lives on the clip already in your song. Solo and mute change its playback and the printed mix — render it in place when you’re ready. No ARA? Use the file-mode VST3 or the standalone app.
Every feature, free for 14 days. Early Access pricing: every 1.x update is included.
Split any song into four stems and turn them into MIDI — with ARA 2, file-mode VST3 or standalone.

Yes. Stooms is an ARA 2 extension: in any VST3 host with ARA 2 support, you open it right on an audio clip in your arrangement — no exporting, no importing. Solo and mute then change the clip’s playback and the printed mix, and the MIDI follows your project’s tempo.
Each stem gets the tool that suits it. Drums become a General MIDI kit — kick, snare and hi-hats are the strongest; toms and cymbals are rougher. Bass and vocals follow one melody line each. Other — keys, guitars, pads — is experimental: a starting point to edit, not a finished part.
Notes writes one clean pitch per note. Expressive writes the same notes plus pitch bend, so slides and vibrato stay in. Set your synth’s bend range to ±12 semitones if it doesn’t pick that up from the file.
Up to 10 minutes. Stooms separates the whole file, or the whole clip in your DAW.
Yes. The standalone app opens audio files directly, and the file-mode VST3 works in any VST3 host without ARA.
Not yet. Logic only loads Audio Units, and on Apple Silicon it runs ARA plug-ins only under Rosetta. Our plugins are native Apple Silicon VST3s, so Logic needs both an Audio Unit version and an Intel build of our engine. It’s coming, but it isn’t here yet.
No. Stem separation and analysis run on your Mac. Activation talks to the licence server; your audio and projects never do.
