I just got a SR 18 drum machine. I leaned on this form that the unit does not have a intro count into a song. (There is no 1, 2, 3, 4). This really makes the unit worthless for live play and rehearsal. How can I start the drum machine and start playing at the same time? I bought this because people really seemed to like it. So I must be missing something. How does everyone cope with the lack of an intro count?
