ACE Step 1.5 music generator

Describe the genre, instrumentation, vocals, and arrangement, then provide lyrics and musical settings. The saved example is a two-minute K-pop song. Output duration sets the audio length; conditioning duration separately tells the music encoder the intended length, so keep both values equal for ordinary use. Music seed controls conditioning variation, while Seed controls diffusion noise. Negative conditioning is automatically zeroed and has no separate negative prompt. The fixed Turbo model uses eight sampling steps by default and exports MP3 audio.
