It is my current understanding that I can…
Make and audio track, vocal melody
Create a solo using this melody.

I know how to make a solo by muting/unmuting/muting an instrument but it has nothing to do with the song’s melody.

Am I mistaken and BIAB doesn’t allow the analysis of a vocal melody so it can generate a solo close to the melody?

If I’m not mistaken, how should I do this, what options should I play with, what documentation is available, etc.

Thanks
