Pro Tools still does not support any non-DigiDesign hardware, because M-Audio is a wholly owned subsidiary of DigiDesign. All this has given us is some cooler hardware options. I don't understand why they feel the need to lock us in at 32 tracks, unless we spend thousands on a high end system. It's a ridiculous limitation that exists for no reason, only to punish the end user.
This is a big reason why I prefer Digital Performer - it lets you use your hardware to its fullest potential, no matter who makes it or how much you paid for it. Track count is relative to your COMPUTER, not your audio interface. I'm not advocating crappy audio interfaces, but right now there is no solution that allows a Pro Tools engineer to have a mobile rig with more than 32 tracks!! It's insane...
