This chassis works beautifully. ProTools was able to update the firmware on the Native card instantly. i could run the same full sessions ( minus the DSP plugins) on the MacBook Pro That I ran on my TDM system with no problems....Full track count and full AAX Native plugins. Works flawlessly and it's PORTABLE! With an interface, and a external media drive you can carry a Pro-Caliber ProTools system in a backpack.
