Oh what the heck. +1
Edited
On second thought I want want to withdraw my +1. Can I do that?
What John3x is proposing is no different than "selective bar freeze". This item has been on the wish list for ages. We don't need a new wish item when you can find this request over and over again here in the forum.
OK! Dan's idea is even better. And should be MUCH easier to implement. And would solve the MultiRiff problem 100%. Just to be sure I understand, here is what I think Dan means!
1) I select the track I wish to work on
2) I freeze that track and then select the bar(s) I wish to unfreeze
3) I click the (new) Regenerate Riff(s) button and BIAB regenerates whatever is unfrozen leaving what is frozen alone (on the track I selected only; all other tracks are unaffected)
4) at this point BIAB freezes my entire track but leaves the changed bars selected
5) If I like the replacement I simply save my song
6) if I don't like the new section I just keep clicking regenerate until I do
OMG, this is exactly how this should be implemented! I don't need MultiRiffs or extra WAV files or a DAW or anything! I just need to unfreeze some bars and click regen until I like the result. And it should be super fast since it is only regenerating a portion of the song and likely on a single track.
PGM, please redo this as described! There is literally NO benefit to the more complicated current MultiRiff solution.
