Mario: Bob, I think my problem is that the 5/4 MIDI styles that I was working with only are available as 4/4. In RB I set the tempo to the style tempo and the time signature to 5/4 but the 5/4 MIDI style still comes up in at 4/4

Hi Mario,
You've come to the right place. We have exactly that, a set of MIDI styles in odd time signatures that fill up a bar of 4/4 as the odd time singnature. This includes time signs like 5/4 7/4 but also esoteric ones like 11/8 etc. use the time sig filter in the stylepicker to find them.

Or just filter for style disk 38: About Time
