A sung track: the prompt below set the arrangement and the script is what the model was given to sing. Copy the prompt, change a word and render your own.
What ACE-Step was given to sing, verbatim. Press play and it follows along.
Line positions are the rendered length divided by 2 lines. Neither model returns per-line timings and there is no forced aligner here, so the highlight follows the playhead approximately.
pop punk revival, palm-muted distorted power chords, fast driving punk drums, melodic bass, urgent young male vocal, gang vocal backing, major key, 168 BPM
'Gang vocal backing' adds three words and gives a chorus that sounds like a room full of people. That is most of what makes the genre feel live.
