thanks for the replies...
I'm trying to change styles with Realtracks in them. I have the "ALLI_GR Crossover Style. (120 RS) for 4 bars for an intro. On bar 5, I want it to change to style "BALADE Ctry Ballad w/el. guit (85 RS). I try to do that with bar settings but it just doesn't work. It doesn't reflect a change in the bar at the very top of the BIAB window either.

I believe I know how to work around it by creating two songs and exporting to my sequencer but thought it would be cool if I could do it all within the same song. It appears that way, but I must not fully understand yet.
