Sonar 8.5 Producer - Session Drummer 3 won't play midi track
I'm new to Sonar, just made the move from Cakewalk Pro Audio 9...
I have a multi-track midi project and have created a Session Drummer track. I dragged my midi drum track onto the SessionDrummer track and pressed play. I hear my midi piano, midi bass, etc., but the Session Drummer only plays the first note of the midi drum track. What have I done wrong?
