You probably already know this, but Pro Tools only works with select hardware.
Just puttin' it out there.
I think the limit for tracks on the LE/M-Powered versions is 32 and I'm not sure on the midi track count.
Tascam's FireOne, etc. - work with ProTools.
Don't get confused between tracks and voices, people. Voices equates to a single channel. So one mono track equals one voice. One stereo track equals two voices. So 32 voices maximum, unless you get the DV Toolkit which ups it to 48 audio tracks (mix and match stereo and mono if you want).
M-Audio was bought out by digidesign, that's why. And m-audio stuff only works with PT m-powered.However, M-Audio gear can run Pro Tools...
if you really dive into pro tools you'll find a lot of advantages for editing in pro tools vs audition.
Gear from Contour Design, Logic Keyboard, Grace Design and CM Labs all work with PT. The CM Labs item is a console which is another interface besides Digidesigns and M-Audio.
Yes, I do understand that control surfaces/interfaces are not the same as audio interfaces. Again, I was just responding to the implication that you're limited by ProTools as to what gear can be used with the system. Sorry to have not been more clear on that. After re-reading my post I can see where it indeed was not clear as to what type of interface I was refering. Again, my apologies Benny.
But I've wanted to upgrade to firewire and not have to buy another piece of pro tools hardware and met with frustration.
