Hi, I'm thinking of getting a midi controller for my new iMac to input some tunes into garageband. This would be a USB midi controller by Edirol of maybe even Korg. Now, since i don't have any experience with midi or mac (just got it today), i'm a bit confused. If i buy this controller, will it work? Would it require special drivers? I've searched the web and there are some topics about those brands supporting Macintels, but those articles are about other hardware.
