Try "fooling" RB by copying the entire data from the transposed track to clipboard, load New and Paste Scrap to track one. Name that file for the instrument, go back and open the original file, do the same thing for the next track to another appropriately named file, etc.

Yes, this is a workaround, but if you have not a fullblown Notation Software handy, it can get the job done.

Then look into the shareware Noteworthy Composer, which I understand has a 30 day free trial.
