I would MUCH rather they just add a bar-by-bar regen operation. Far, far simpler to use. I appreciate your idea but it is complicated to even comprehend much less to use.

Just add a little arrow to each bar and when I click the arrow a small dropdown entitled Regen appears and it lets me click a track to regen. NOTHING else in the song changes. It is fast and simple to understand what is happening. I can instantly play and hear the change and if I like it I freeze the entire track and I'm done. If I don't like it I just try again.

As for RealTrack segments or riffs that don't fit in a single bar give me an option to ignore them or use them. If "use them" then go ahead and alter a bar before and after my selection.

Oh and make UNDO work on this to be able to step backwards if I want to.
