Ableton Live 12.3 dropped
Ableton pushed a 12.3 update that adds Device Comparison for quick A/B of instrument and effect settings, Stem Separation to split audio into vocals/drums/bass, and new Bounce actions that let you bounce tracks/groups and copy resulting audio directly into a set. The update also ships Move 1.8 with improved slicing and navigation tools aimed at faster remix workflows. (dopperfx.com) (dopperfx.com)
Ableton has released Live 12.3, a free update for Live 12 users that adds stem splitting, faster bounce tools, and A/B device comparison. (ableton.com) Live is a digital audio workstation, the kind of software producers use to record, arrange, edit, and perform music. In Live 12.3, Ableton added Stem Separation in Live 12 Suite, which can pull vocals, drums, and bass out of any audio clip in Arrangement View, Session View, or the Browser. (ableton.com) Ableton said Stem Separation in Live 12.3 Suite uses machine learning, a pattern-finding system trained to sort mixed audio into separate parts. The feature is only in Live 12 Suite, not Live Standard, Intro, or Lite. (ableton.com) Performance depends on the computer running it. Ableton said Apple silicon Macs use the graphics processor for faster stem processing, while Intel Macs and Windows computers use the central processor, and 16 gigabytes of memory is recommended for frequent High Quality use. (ableton.com) The update also changes how users print audio inside a project. Live 12.3 lets users bounce entire groups in place or to a new audio track, and Paste Bounced Audio can copy the rendered result directly back into the set for edits, transitions, and resampling. (ableton.com) Ableton also added Device A/B, which the company describes as a way to compare two versions of an effect or instrument setting instantly. That targets a routine problem in mixing and sound design: deciding whether the last tweak actually improved the sound. (ableton.com) Live 12.3 arrives as Ableton keeps folding more sample-manipulation tools into the core program. The same release adds Splice browsing inside Live’s Browser, so users can audition subscription samples in sync and in key without leaving the app. (ableton.com) The companion Move hardware also got a 1.8 update on November 25, 2025. Ableton’s release notes say Move 1.8 adds the new Auto Pan-Tremolo effect, two Kučka drum kits, and raises the sample limit for Move sets to 800 megabytes. (ableton.com) Ableton has kept tuning the 12.3 branch since launch. Release notes published through March 3, 2026 show follow-up fixes for Bounce to New Track, including track numbering, silent group bounces, and nested group effects being applied twice. (ableton.com) For producers, the practical change in Live 12.3 is simple: more of the remix workflow now happens inside Ableton’s own window, from splitting a song into parts to rendering a variation and dropping it straight back into the set.
