Hi Grey Wolf,I don't know which of these links have midi files but they all have some sort of notation or sound files for drum rhythms.
I'll probably go an check them out again now just to see what format they are in.
The taalwizard is a downloadable program with lots of rhtyhms, although mostly Indian drum rhythms I think.
