Adding Rhythm sets (in 9/8)

[jasihn]

I'm playing a wedding next weekend and need to play a Bulgarian dance tune in 9/8. I've only experimented with the rhythm sets that are built in and there's nothing in 9/8. How difficult would it be to create this from scratch, or download something? A very simple rhythm is all that I'd need.

I've never created one before and the documentation is a bit daunting. Any help is appreciated.

If interested, this is the tune... http://www.youtube.com/watch?v=T99Z-3MoBOk
