Drumming program

Anybody know of any really good drumming program for pc? I play drums but want to be able to send comps and stuff to my guitarbuddy, and I don't have an electronic kit.
Please excuse any bad spelling and stuff, I'm from Sweden (not an excuse)

try using guitar pro 5. its not a drum program but you can write notes for drums so your buddy can get an idea of what you want him to know. try checking it how it works on youtube. i use it alot with my bandmates.
