Ableton Live 12.3 is in public beta – featuring Stem separation, Splice integration and moreAbleton isn’t slowing down. Just months after rolling out Live 12.2, the Berlin-based company has launched the public beta for Live 12.3, and it comes stacked with features fans have been asking for.
At the top of the list is Stem Separation, powered by algorithms from Music AI, the creators of Moises. Users can now split vocals, bass, drums, and other sounds from any audio clip in Arrangement or Session View, or within the Browser. It’s a feature that has been creeping into other DAWs like Pro Tools and Logic Pro, and Ableton’s take opens up a ton of new options for sampling, reworking and inspiring ideas.

Splice integration is another major upgrade. Instead of juggling between apps, Splice users now get direct access to Splice’s full library of royalty-free sounds inside Live’s Browser – making it easier to filter, search and audition Splice samples in sync and in key with your project.
With the new ‘Search with Sound’ feature, you can even capture audio from your project and have Splice suggest samples that fit the grooves and harmonies of your track. Once you land on something you like, you can drag it from Splice and drop it straight into your session.

Live 12.3 also expands on 12.2’s Bounce to New Track tool with a new Bounce Group feature, which lets you bounce an entire Group track in place, including all its processing, to a new audio track. The new Paste Bounced Audio shortcut (just hit cmd/ctrl + opt/alt + v) makes it easy to paste clips as bounced audio into any track or take lane, perfect for quickly committing to ideas or stacking variations.
Meanwhile, Auto Pan has been renamed Auto Pan-Tremolo, and now features an updated interface, including dedicated modes for panning and tremolo effects. The new tabbed layout lets you switch instantly between the two modes, and each has deeper modulation controls and a wider range of time modes for greater rhythmic control.

Another sleeper hit in this update is the new A/B feature, which allows you to quickly set and compare two parameter states for every built-in instrument, audio, and MIDI effect in Live. You can, for example, use state A for tweaking values while leaving state B at the device’s default settings, and then switch between the two (with the tap of the ‘P’ key) to assess the differences.
Live 12.3 also adds fresh Packs and Max for Live tools. The new Generators Pack gives Live Standard and Suite users access to Patterns, a percussive MIDI tool designed to spark rhythmic ideas, along with Sting, an acid bass pattern generator inspired by a popular Max device of the same name.
Push 3 users also score big. In addition to Stem Separation, Bounce Groups, and the updated devices and Packs – all of which are coming to Push 3 Tethered and Standalone – Live 12.3 offers Push 3 users new ways to play with the instrument’s expressive pads.
A new XYZ layout transforms the controller’s pads into an expressive touchscreen for your racks, instruments, and effects – simply slide your finger across Push’s pads to shape the sound, and press to trigger punch-in effects. The Rhythm Generator Drum Rack layout brings Live’s generative beat-making straight onto Push, while touch-sensitive step editing makes humanising beats faster than ever. Plus, with class-compliant audio interface support, Push Standalone can now handle more complex setups, like recording using your interface’s mic preamp or running live rigs through DJ mixers.
