 Live Suite now features Stem Separation from audio tracks in both Session and Arrangement mode. The process extracts 4 different stem types: Bass, Vocals, Drums and Others. 
 
-You can use this feature by right-clicking on a desired clip in a track or in the browser and selecting stem separation in the pop-up menu. The Others stem captures everything in the selected audio clip that does not fit into the Bass, Drums, or Vocals categories. The stems will be nested under a new group track which has all the effects which were present on the original track.

-The separation processing time heavily depends on your system's configuration. On older Windows computers, Intel Macs and Mac computers running macOS 11 Big Sur processing times might take a longer time. Due to compatability issues, stem separation will also run slowly on Apple Silicon computers with macOS 26.1 Tahoe. See the following article for more information on macOS compatibility with Live.
