Jamstix Interactive drummer by Rayzoon , http://www.rayzoon.com/, is used exclusively on all of my music. I have been using it for almost a year now and still continues to blow my mind how real it plays. The interface is very easy to use and like anything else takes a short time to navigate how it operates. It has tons of controls and parameters to modify how the drummer model plays and reacts to the song pattern you create. Rayzoon offers expansion packs and drummer model add ons to give you infinite percussuon possibilities. This is a great weapon to have in any home studio arsenal.
