Hi, I’m a keyboard player with a studio, and for incoming drummers I researched and bought a Hart Dynamics 5.3 pro kit, Roland TD-12 module ( for trigger to midi conversion only) and wish to use SD2 for live rehearsing and eventual recording. I currently have a Mac G4 but will be upgrading. My concern is latency, latency, latency. In the superior drummer manual and other literature, the “dedicated” midi interface is urged, and drawbacks of USB “jittering” are mentioned. How else can you get midi into a current Mac computer without using USB? I am looking for recommendations for the “BEST” midi interface for my situation and lowest latency, and can anyone back it up with specs or antedates? Also, IN SD2 can audio latency be adjusted below 64? There doesn’t seem to be a option for this, but I am new to the software. Thanks everyone!
