Ableton Live 12.3 Beta: First Look at Stem Separation, Splice Integration & More

Introduction: A Huge Update for Ableton Users

Ableton just dropped the Live 12.3 beta, and it’s packed with features that producers have been waiting for. From game-changing stem separation to direct Splice integration, this update feels like a leap forward in making your workflow faster and more creative.

I got early access to the beta and put together a quick video walking you through all the major updates — plus a hidden tip to get the highest-quality stems possible. Let’s break it down.

Stem Separation: The Big One

This is easily the most exciting new feature. Stem separation lets you split audio into vocals, drums, bass, and other elements right inside Ableton. No third-party tools required.

But here’s the catch — the quality depends on how you set it up. In my video, I show you exactly how to configure the options.txt file (available for everyone in both my YouTube or Patreon communities) to unlock better results.

New Workflow Enhancements

Beyond stem separation, Ableton added some subtle but powerful workflow upgrades:

• Splice Integration: Browse and import samples directly from Splice without leaving Ableton.

• Bounce Group in Place: Render grouped tracks instantly without extra routing.

• MIDI to Audio Shortcut: Convert MIDI clips to audio faster than ever.

• Auto Pan Tremolo Mode: A new creative modulation option for more rhythmic movement.

• Device A/B Switch: Quickly compare settings on any Ableton device.

These small tweaks add up to a smoother, faster creative process.

Why This Update Matters

The Ableton 12.3 beta shows that Ableton is listening to producers. By blending creative features (like stem separation) with practical workflow improvements (like bounce in place and Splice integration), this release gives you both new tools to experiment with and ways to speed up your sessions.
