The question was about 5/4 styles. I think it's not a weakness of the offering, but an acknowledgement that compound time signatures can be interpreted so many different ways (and I'm not even talking about notation). Last I looked, there were at least two midi styles in 5/4. One was based off of the Mission Impossible theme. The other was based off of Brubek's Take Five. Both are named appropriately. MISSION divides the "feel" into 3-2. Brubek's divides it into 2-3. I'm not sure I've ever encountered any, but I can "hear" divisions like 2-2-1 and 1-2-2. How many styles would have to be created just to get those basic feels? And variety? Fuggetaboudit.

I've worked quite a bit in 7/4. It could just as easily be notated as 7/8 in a different tempo. I've used real-tracks and midi tracks with a feel of 3-4, and with a feel of 4-3. Fine so far...but what if the feel/groove is 2-2-2-1 or 2-2-3? The notation might not look pretty, but I could do it (and any other combinations of grooves) in any of those feels with either real tracks or midi.

Granted, some "Styles" may work better than others, but I could set up four bars and audition styles all the dang day long. Adding what would need to be possibly hundreds of new styles to deliver usable variety for much lesser used time signatures "just because" seems a waste to me--especially when (with a little creativity and ear) we can make our own.
