ACE-Step Music: AI Music Generation in DaVinciDreams

What is ACE-Step Music?

ACE-Step Music is a music generation model from PiAPI available in DaVinciDreams. It processes text input and generates audio up to 300 seconds long. Priced at $0.00 / sec, it is one of the most affordable options in its category. Within DaVinciDreams, ACE-Step Music is used to generate voiceover narration, dialogue, sound effects, or background music for your film projects. Generated audio clips are placed on dedicated audio tracks in the multi-track timeline, where you can adjust volume, apply trim points, and synchronize them precisely with your video clips. The AI handles the audio production; you control the mix and timing.

Key Capabilities of ACE-Step Music

ACE-Step Music generates background music and soundtracks from text descriptions. You describe the mood, genre, and instrumentation you need — cinematic orchestral, lo-fi hip hop, ambient electronic — and the model creates a matching audio track. Generated music clips can be up to 300 seconds long and are placed on dedicated audio tracks in the timeline. The DaVinciDreams editor handles volume mixing, fade in/out, and precise synchronization with your video clips. This eliminates the need for licensed music libraries or custom composition, letting you create a unique soundtrack for every project.

Using ACE-Step Music in DaVinciDreams

ACE-Step Music integrates into DaVinciDreams through both the Script Generator and the direct editor workflow. During script generation, the system automatically assigns ACE-Step Music to produce background music for each scene. In the editor, you create audio prompts manually, select ACE-Step Music, configure parameters like duration and style, and generate. Audio clips arrive on dedicated timeline tracks where the AudioMixer handles volume, panning, and synchronization. The BYOK system accepts PiAPI API keys for cost reduction. Generated audio is stored in R2 and served via CDN.
