Any way of using material in the Guitar Pro drum matrix as a MIDI item in Reaper?

Title pretty much sums the question up - my drummer's written a part in Guitar Pro to correspond with a the rest of a song our band has recorded, but his drums are currently unavailable. Is there any way of using what he's made in Guitar Pro and treating it like a MIDI item if I download some drum samples?

Thanks guys, appreciate it!

Make sure only the drum track is present, then go file - export - midi

Then just open up the midi file in Reaper
