Following this discussion-
http://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=424547#Post424547on the Realband wish list forum, Jim Fogle suggested I post this in TIPS & TRICKS.
If you use the command "SAVE ALL TRACKS AS WAV FILES" Realband will create a folder containing the tracks in the same directory as the SEQ file. If you subsequently edit one of the tracks in the SEQ file and use the command again, Realband creates an additional folder containing the new track, plus all the wav files from before.
An alternative is to highlight the edited track and use the "EXPORT HIGHLIGHTED TRACK" instead. This gives you the opportunity to choose the location for the track, so you can just overwrite the track in the original folder. An easy way to highlight any part of the track is from the BARS window, which is also a great place to CUT/COPY/PASTE across muliple tracks.
If you then save the SEQ file with a new number, which is good practice every time you make a change to a project, you can always roll back if needed.
That's about it, really....
