Stem Separation, which came to Live Suite in 12.3, is now more flexible. You can now separate a selected portion of a clip in Arrangement View, or process only the playable portion of a clip, rather than having to process an entire clip every time. Separated stems can now be merged onto a single track rather than generating individual tracks each time, making it simpler to remove specific stems like vocals. Finally, Stem Separation is now easier to monitor with a unified progress bar that tracks the entire operation, rather than per-stem.
It’s now even easier to use Push as a hub to connect, play and control all of your gear thanks to Link Audio and MIDI Mapping. 12.4 lets you create and modify MIDI Controller mappings from Push, and customize which control scripts your connected MIDI device uses. Control scripts can also be deactivated entirely, so that you can use custom mappings without conflicts. MIDI Mapping is also partly accessible via Live on Push 2 and the tethered version of Push 3. On Push Standalone, Link Audio lets you receive and share audio with other compatible devices, and individual channels of audio can also be shared.
12.4 also offers more detailed control over Max for Live devices. A new Visible option allows Max for Live devices to add more parameters directly to the device view on Push 2 and 3. This expands the range of parameters that can be controlled on Push to features like modulation mapping in LFO or calibration in CV Instrument.
