ACE-Step 1.5 Edit Stem Extract pulls one clean stem out of a fully mixed song. Feed any track and pick the part to isolate from 12 options: vocals, backing vocals, drums, bass, guitar, keyboard, percussion, strings, synth, fx, brass, or woodwinds. An optional prompt hints at the stem's character, and you can render up to 4 variations to choose from. Built on the full-quality ACE-Step 1.5 edit engine. Ideal for remixing, sampling, karaoke and backing tracks, sound design, and cleaning up references.
