Remix.

Remix separates a mixed track into vocals, drums, bass, piano and a fifth stem for everything else, live as the session plays rather than in an offline render. Each stem has its own fader, solo, mute and sensitivity, so you can lift a buried vocal, tame busy drums, mute the vocal for a karaoke track or duck a song's vocal under dialogue. Stem outputs send parts to their own tracks where the host allows. It runs at up to 96 kHz; the AAX version needs Pro Tools 2018 or later.
