A question for you my friend is does RB export a 5/4, well actually any non 3/4, 4/4, song in 5/4 or whatever time signature you are using?
I am not a user of RB but IIRC it use to export everything in 3/4 or 4/4 time.
Export to where?
In my experience yes, but you may have a specific example that shows otherwise (?).
TommyC and I have traded RB files in 7/4 multiple times with no issue.
One of my favorite things about RB is it's odd-time abilities.
Are you remembering BB or RB?
Come to think of it, 11/4 and other time sigs have worked also.
I don't attempt this in BiaB, as RB handles it so much better to me, so that be a huge difference in the results.
