01
What it is
ACE-Step 1.5 is an open-weight music model, run here as its XL turbo variant. You describe the style in tags (genre, instruments, mood), optionally write lyrics, and get a mixed track with vocals; tempo, key and scale, time signature and lyric language are settings rather than guesses.
It powers Create Music. Tracks default to 30 seconds; the app writes WAV files into your library like any other output.
