My first guess would be that there is a problem with your midi setup and that you are hearing real drums, but not hearing any midi. At the top of your screen, what color are the various instrument tracks? If they are green, they are real tracks (which are audio). If they are yellow, they are midi tracks. I think the default is to always substitute real drums (which are audio), so even a midi style will play with real drums.
