The drums are from the Instant Drummer sessions included in Riffworks-you can buy add ons from their website -They record live drum sessions with different artists and you can some what control them.I think the one i used is Matt Sorrum.
They are seperated into verse-chorus-bridge and you can adjust tempo and intensity.They work pretty well and i am not an expert with it yet .Some people can really get a great sound out of them.
