Splice Integration and Stem Seperation Arrive in Ableton Live 12.3 Beta

Live 12.3 introduces real-time stem separation and direct Splice integration, expanding audio manipulation capabilities inside the DAW. The update also enhances Push 3’s expressive features and supports broader hardware compatibility.

Ableton has announced that Live 12.3 is now available in public beta. One of the central additions is stem separation, now available in Live 12 Suite and Push Standalone. The feature allows producers to extract vocals, drums, bass, and other elements from audio clips using algorithms developed by Music.AI.

Splice Integration

Live 12.3 also introduces direct integration with Splice. Users can now browse and audition Splice samples within Live’s Browser, synchronised with project tempo and key. The “Search with Sound” feature enables users to identify rhythmically and harmonically compatible samples by dragging in audio from a clip or selection.

Bounce Groups and Paste Bounce Audio

New functionality also enhances the handling of audio groups and bounced material. Building on the “Bounce to New Track” feature added in Live 12.2, users can now bounce entire Group tracks or specific segments. A “Paste Bounced Audio” tool allows audio to be pasted directly into tracks or take lanes, enabling faster editing and resampling workflows.

Two new MIDI tools are introduced through the Generators Pack by Iftah. “Sting,” adapted from the acid bassline generator, and “Patterns,” which facilitates quick percussive rhythm creation, add to Live’s built-in sequencing capabilities. An updated version of Auto Pan – now called Auto Pan-Tremolo – features a revised UI and expanded modulation options, and becomes available across all versions including Move, Note, and Live Lite.

Live 12.1’s Sequencers Pack adds support for reproducible arrangements, and Live 12.2’s Expressive Chords Pack gets a new Chord Edit mode – the device now lets you transpose selected chords, and even input your own with the ‘Learn’ function.

Push 3 sees expressive updates and interface expansion

Push 3 hardware users gain several expressive tools in the new update. A newly introduced XYZ pad layout allows finger sliding and pressure to manipulate rack and device parameters in real time. The Rhythm Generator layout offers intuitive rhythmic pattern creation via four vertical sliders, while a new touch-sensitive editing mode lets users adjust note velocities gesturally.

Support for class-compliant audio interfaces on Push Standalone is also included, enabling broader hardware compatibility and use in live performance or studio setups. Features like stem separation, bounced audio tools, and the updated Packs are all extended to Push 3 users.

Update available to existing users, final release pending

Live 12.3 remains in public beta, with the final version to be available as a free update for all Live 12 license holders. The update continues Ableton’s incremental rollout of features through the 12.x series, which has so far included new packs for sequencing and chord control.

Over the past year, Splice has moved beyond third‑party plugin tools and become directly embedded into DAWs like PreSonus Studio One and Pro-Tool, and now Ableton Live 12.3 is following suit. This signals growing interoperability between Splice and major DAW platforms – meaning producers can expect to stop relying on intermediaries like Splice Bridge. Meanwhile, Push continues to build on its legacy as a live‑performance instrument – the original purpose of Ableton Live – suggesting that Live 12.3 furthers that performance ethos.
