AI Stem Separation in Ableton Live

Updated May 9, 2026

AI stem separation is the process of taking a finished audio file — a song, sample, or loop — and splitting it back into its constituent musical elements (drums, bass, vocals, and everything else) using a deep-learning source separation model. In 2026 the state of the art is Demucs, an open-source hybrid transformer model that produces clean, usable stems for production work without the cloud-upload friction of online services like LALAL.AI, Audioshake, or Moises.

How do producers do this manually in Ableton?

VIXSOUND brings stem separation directly inside Ableton Live as a chat command. Drag any audio file into the chat panel, ask for the stems, and four (or six) new tracks appear in your session — fully edited audio you can chop, transcribe to MIDI, resample, or remix.

How does VIXSOUND speed this up?

The whole pipeline runs locally on Apple Silicon: no upload, no waiting on a remote queue, no licensing question about who owns the separated audio. Below: how the workflow looks in practice, how it compares to Ableton Live 12's native Stem Splitter and to cloud services, and what to use it for.

Three workflows producers reach for first

Workflow 1 · Sample chopping

Pull a vocal hook out of any old record

Drop a sample. "Separate vocals only and warp it to 88 BPM." The vocal stem lands on a new audio track, time-warped to your project tempo, ready to chop. The drums, bass, and instrumental are also on tracks if you want them — usually you mute them, but they're there.

Workflow 2 · Reference learning

Solo the kick of a song you love

Drag your reference track. Separate. Solo the drums. A/B against your kick. Solo the bass — analyse the relationship to the kick. Solo the vocal — study the FX chain you're hearing. The whole reference-listening workflow happens inside the session.

Workflow 3 · Remix bed

Build a remix from the original parts

Separate, mute the drums and bass, keep the vocal and pads, build a new arrangement under it. Or transcribe the bassline to MIDI and re-route it through your own bass synth. Audio-to-MIDI chains directly off the separation step.

Frequently asked questions

How does AI stem separation in Ableton Live work?
VIXSOUND uses Demucs, a deep-learning source separation model that runs entirely on your Mac. You drag any audio file into the chat panel inside Ableton, ask the AI to separate it, and four stems — drums, bass, vocals, other — land on four new tracks in your session. Typical processing time is 20–40 seconds for a 3-minute song on Apple Silicon.
Is my audio uploaded to a server?
No. Stem separation runs locally on your Mac. The audio file never leaves your machine. This is the main reason producers prefer VIXSOUND over LALAL.AI, Audioshake, and Moises for client work — there's no chain-of-custody question.
How does this compare to Ableton Live 12's built-in Stem Splitter?
Ableton Live 12 ships with a native Stem Splitter as of the 12.1 update. It's good for quick splits inside the DAW. VIXSOUND complements it: VIXSOUND uses a different model (Demucs hybrid transformer) tuned for sample-chopping use cases, supports batch separation across many files at once via the chat ("separate all the drum loops in this folder"), and chains separation with downstream actions like audio-to-MIDI transcription. Read the full comparison: /blog/ableton-12-stem-splitter-vs-vixsound.
What stems can I separate?
The 4-stem model gives you drums / bass / vocals / other (everything else — usually keys, guitar, FX). VIXSOUND also supports the Demucs 6-stem model for finer-grained separation (drums, bass, vocals, other, guitar, piano) when the source material warrants it. Ask the AI which mode to use for your sample.
What quality should I expect?
Demucs hybrid transformer is state-of-the-art for open-source separation as of 2026. Vocals and drums are excellent. Bass is strong. Guitars and keys (in the 6-stem model) are good but show some bleed on dense mixes. For most production use cases — sample chopping, reference learning, remix work — the quality is well past the threshold of usable.
How many stems can I separate per month?
Starter ($9/mo): up to 5 separations per month. Studio ($29/mo) and Ultra ($79/mo): unlimited. Each separation costs 10 credits on Starter, included in the unlimited tiers.
