The site Udio offers the option to upload audio, which can be used as starting point or as source for a remix, for which you can provide a prompt. I took the intro from an old track and tried it. Pretty amazing!

I used this AI to remix my own ‘Infinity’ track, and asked Udio to add several parts after that. A cool way to rediscover your own music again. The melodies and instruments are roughly the same, but in a new version.
