ACE Studio & StepFun: ACE-Step Prompt

ACE-Step Prompt offers a natural-language workflow for the ACE-Step music foundation model. A brief can describe the scene, genre, mood and intended character of a song in one place, supporting both vocal and instrumental music. It is useful for exploring an idea before writing a separate lyric document; creators with fixed words can use the companion tags-and-lyrics version. Seed and requested-duration controls support repeated exploration of the brief. Use cases: exploratory song concepts, mood-led compositions and instrumental background cues.
