USB ports cannot be accessed "the hard way" -directly- as it was (and is) possible via the serial port. The AMT8 connected to a real mac serial port (like the stealthport) includes all the special timing benefits of ATM transmission (compared to MTPs/express under logic!) as well as it saves cpu processing power compared to a direct USB-connection (really, no kidding!!); at this point in time the good old RS422 is the most stable way to connect usb-macs with midi gear like AMT8/U8-mkII and therefore should be preferred. Finally- if you haven´t switched to an usb-powermac yet, just relax and call emagic support when you really plan to upgrade your mac; ask them about their recent experiences with direct USB/AMT8 connections, and when they tell you everything would be fine -plug&play :-) Kai
