With the UseTracks you are best using RealBand as you can generate/re-generate up any section you like.
The problem with UT at the moment they don't play the A or B sections where they should and the Stereo UT render to mono that makes them sound #$^%$%.
This B3 is in Stereo but will sound %^## in Mono.
The B sections are playing in the A.
Just highlight the section you need then UT > Favorites to regen.

Here is the UT you can try, it is just something I whipped up.
I included the notation in the SGU's so you can change and add things.
You can click on Bar Setting F5, and get the UserTracks Bar Settings when you open the SGU's.
Endings don't always generate so just highlight the ending and regen.
