Does the continuation replace my file?

No. The new version is saved as its own song in your library and the source track stays as it was.

How long can the extension be?

The new section uses the same length and weighting rules as a normal generation; only the part before the extension point is taken from the source.

Yes. Upload or import the audio first, then extend it like any library track.

Good to know

Extend adds new music after part of an existing track. You mark where the original stops being the reference and describe what should come next.

Source track: The song to continue, from your library or imported from your device.
Extension point: Where the continuation begins. It has to sit inside the track, after the start and before the end.
Style: The direction for the new section. Keep it close to the original or take it somewhere else.
Extension prompt: What should happen next: a chorus, an instrumental break, a key change.
Instrumental: Extends the track without vocals.
Title: An optional name of up to 80 characters for the new version.
