Cadence Extend · FAQ
Can I use my own lyrics?
Use Lyrics & style to prepare lyrics, musical style and an optional title, then review the request. The demo still plays fixed synthetic audio; live song generation is not yet available.
Does the demo generate real songs?
No. It returns two fixed audio samples from one isolated demo item. There is no real provider call or credit charge.
Why do two tracks share one task price?
The music model returns its native pair of works from one execution item. The item is settled once, rather than treating each audio file as a separate item.
Can I upload a song to extend or separate stems?
You can preview a supported file locally. Upstream reference-audio processing, extension, covers and stem separation are not connected, so those submissions are blocked.
Are the lyrics timed and can I export WAV?
The current page displays submitted lyrics without invented timestamps. Timed lyrics, actual WAV exports and commercial-use terms require the corresponding verified provider support.
