Ableton Live 12.3 Beta: Native Stems & Splice Integration Arrive

Ableton Live 12.3 Beta: A Game-Changer for Producers

On October 15, 2025, Ableton released the public beta for Live 12.3, a landmark update that directly integrates some of the most requested features into its celebrated digital audio workstation. This release focuses on streamlining creative workflows, particularly for sampling and remixing, with the introduction of native stem separation and a deep integration with the Splice sample library.

A New Era of Sampling: Native Stem Separation

The headline feature of the Live 12.3 beta is the long-awaited arrival of native stem separation. For the first time, users can isolate core musical elements from any audio clip without ever leaving the Live environment. This powerful tool is available for all users with a Live 12 Suite license or a Push 3 Standalone unit.

The process is remarkably simple. Users can right-click any audio clip and select from a new menu to split the audio into four distinct stems:

• Vocals
• Drums
• Bass
• Other (which typically includes harmonies, synths, and other melodic content)

Live then automatically creates new audio tracks for each separated stem, leaving the original source file untouched. This non-destructive workflow allows for endless creative experimentation.

The Impact for Producers and DJs

This integration is a massive workflow enhancement. Previously, creating acapellas or instrumentals required using external websites, standalone applications, or third-party plugins. Now, producers and DJs can:

• Instantly create remixes and bootlegs by isolating the vocals from one track and layering them over the instrumental of another.
• Sample with precision by extracting a clean drum break or bassline from a full song for chopping and re-sequencing.
• Prepare live performance sets by creating instrumental backing tracks or performance-ready loops on the fly.

Splice at Your Fingertips: Seamless Browser Integration

Live 12.3 also introduces a full-fledged integration with the Splice sample library directly within Live's browser. This moves beyond a simple plugin and embeds the massive Splice catalog into the user's creative space.

Users can now log into their Splice account from Live and browse samples with powerful filtering options. The standout feature is the ability to audition samples in sync with the current project's key and tempo before downloading. This eliminates the guesswork and friction of finding the right sound, allowing for a more fluid and uninterrupted creative process.

Big Upgrades for Push 3 Standalone

Push 3 Standalone users receive significant enhancements in the 12.3 beta that further solidify the device as a self-contained production powerhouse. The update delivers expanded expressive capabilities, including new tools for MPE (MIDI Polyphonic Expression) editing directly on the Push 3's screen.

Additionally, new pattern creation tools and sequencing modes, such as Euclidean rhythm generators, have been added. When combined with the new stem separation feature, Push 3 users can now sample a track, split it into its core components, and begin building entirely new ideas without ever needing to connect to a computer.

How to Access the Beta

The Ableton Live 12.3 public beta was made available on October 15, 2025. It is open to all owners of a Live 12 Suite license and registered Push 3 users. Eligible users can download and install the beta version through their account on the official Ableton website.
