In the music gen UI, using a reference audio file is forcing the song to that length, is it supposed to ignore the duration parameter like that?

I thought the music reference file would maybe apply its "sound" to what you generate.

Also, I tried using generated audio as the reference file, but that just immediately errors out.

You can use a generated audio as a reference file. What error do you get?

Generally, you should treat the reference file as "Img2Img" in stable diffusion - because that's what it is. It modifies the original audio with a partial denoise. So it will always be the same length.

Thanks for the clarification.
The error I had was very generic like "There was an error" or "Failed to generate", but I'm unable to reproduce the issue I had after a couple of reboots. I'm guessing it was related to file permissions.

Alright, glad it's working.
