I'm new to Superior Drummer, having just cross-graded from EZ2. So maybe this is possible, and I just haven't found it. What I would like is the ability to import a stereo audio file (sans drums) into the Grooves/Song Creator interface so I can construct a drum track in the standalone interface. The reason for this is, I find it cumbersome to have to keep switching windows between Logic and SD3 to stop and start the song. Maybe there is a way to have SD3's transport control playback in Logic, but I haven't found it.
Thanks for such an awesome product line!
