...Just tried generating a RT onto one of the black-font, uncooperative guitar tracks, and as soon as it generated, it became green like the others, but then that means I sacrificed the old guitar track (which I liked, except it wasn't the right chords) in order to turn it green...

One thing I notice is that these "problem" tracks that go from blue to black during the "Tracks>Make all" operation (and thereafter fail to obey chord edits) are listed as things like "RealGuitar 362: Guitar, Electric...", whereas when I go in and force a generation of another RT onto a black-font one, it then has a name like "RT365, Guitar, Acoustic..." after it turns green. So, abbreviated. Maybe not important but I thought I'd mention it.

That said, there were other RT's listed as "RealBass..", etc., just like the "problem" tracks, but which converted to green "regular" tracks just fine, and obeyed the chord changes. Somehow, RB is seeing certain RT's as "user" data or something, and exempting them from "Tracks>Make all". Seems to me...
