Hi Keith I bought an alphatrack about two years ago for use with sonar. I have to admid that I don't use it very often - not because it's not great. But I got very disapointed with a mackie control surface and with DAW's in general. So that's why I don't do much anymore if I don't have to. I don't have a mac, at least not yet. but if there's anything about the Alphatrack which I could check out for you, just let me know. All I know about my short use is that the fader is pretty quit and the time strip is a nice cool thing. Ben
