I'm about to purchase the Alpha Track so I don't have to rely on the iPhone app for DP7 that was just relaesed for Free.  I know at least this should work seamlessly being created by Motu. But I want a Fader.

Does the Alph track work with DP 7.12, Snow Leopard, and 27" iMac Quad Core? 

What are the limitations between hardware labeling on AT and DP Software Symantics?  What doesn't work?

Do the 3 encoder's work with DP's Masterworks EQ and Limiter? 

I usually work in DP's Pro Tools Window Set for evertyhthing I need to do.

I'm also looking at the Presonus Fader Port for $70 less.
