I'm looking to possibly upgrade from my trusty old Dr. Rhythm machine, and wondered if anyone had any experience with drum machine software that's Mac friendly. I saw a program in a store today that wasn't half bad - I think it was called "Groove Agent" - but I didn't have time to really mess with it enough to see if it would work for me. Programs with lots of jazz sounds/patterns especially appreciated. Basically, I'm looking for something that sounds like an acoustic jazz kit with various patterns that I can practice with. If it matters or helps, I run DP4 on the same computer.
