Bummer. I like the M-powered demo but am hesitant to do it if I am limited to 2 in/out. Since M-Audio says multiple cards (of the same or different types) are not supported, I wonder what happens when someone like Trood who already has two cards installed tries to use the M-powered program. Is Protoola able to see all the cards but somehow limited to only accessing one? If so which one? Does PT choose whichever card is the system default? Does PT give the user the option to choose which card, and if so can the choice be easily switched back and forth, or is it pretty much set? What if there's yet a third card in the system, not of the M-Audio variety, set as the system default? What does PT do then in terms of which M-Audio card to choose? Dave
