Ableton Live 12.4 is out, here’s what changed with Stem Separation, Erosion, Delay and more

Three months after entering public beta, Ableton Live 12.4 is officially out today — a free update for all Live 12 license holders. The release has been on producers’ radar since February, largely for what it does to Stem Separation, but the feature generating the most attention heading into launch is Link Audio, a new way to share audio between devices in real time without any additional hardware.

Updates to Stem Separation

Stem Separation arrived in Live 12.3 as a compelling addition with some practical limitations — mainly that it processed entire clips rather than selections. In 12.4, Ableton has addressed that directly. Suite users can now run Stem Separation on specific time selections in Arrangement View, so if you only need to isolate 16 bars of a mix, you’re not waiting on the whole track. Individual stems can be removed with the rest consolidated into a single track, and a single progress bar now covers the full operation rather than updating stem by stem.

Link Audio

Link Audio is the genuinely new concept in this release. It lets compatible Ableton devices stream multi-channel audio over a local network — no extra hardware, no manual latency compensation. You can send audio from Move or Note directly into Live or Push Standalone, and other players’ audio appears as a regular input. For producers collaborating in the same room across multiple Ableton setups, it removes the physical routing that previously made real-time audio sharing impractical.

Erosion, Chorus-Ensemble, and Delay Get Updated

Three built-in devices have been revised. Erosion is the most notable: it now shows real-time spectrum visualization so you can see what it’s doing to your sound as you adjust it, and adds continuous blending between sine and noise modulation and between mono and stereo noise — more control, less guesswork. Chorus-Ensemble gains finer control over delay time and structure, particularly useful on guitar and bass. Delay picks up new LFO time modes and waveforms.

Learn View, Push, and Move

The Help View has been replaced by Learn View, video-led tutorials with written explanations and a progress checklist across core Live workflows. Push Standalone gains the ability to create and edit MIDI controller mappings directly from the device, with options to customise or deactivate control scripts for connected hardware.

Move 2.0 and Note 2.0 ship alongside the update. Both now support audio recording via microphone, library clip browsing, and audio warping. Auto Shift and Erosion are available as effects on both devices. New demo Sets from Heavy Mellow, Alice Ivy, and Jose Castillo are included.

Live 12.4 is free for all Live 12 users and installs automatically the next time you open Live. Manual downloads are available through your Ableton user account.
