MAZ doesn't know what a tracker is, and I think Buzz is NOT at all like a tracker.
Haven't seen Modplug Tracker, but on the PC, you have the good old FastTracker 2.something, and the new Renoise. They are good, "faithful" trackers. Check' em out Fisken, Renoise even accepts VSTis if that's your kind of thing, and all is under the sweet familiar "protracker-like" interface. Running under Windows of course.
