Hello! I am looking into Pro Tools 8 but I'm a bit confused about what I need for it. I have been reading quite a bit on the Digidesign website, and it says that I need a ProTools HD or ICON system. Would this (http://www.digidesign.com/index.cfm?navid=62&itemid=34329) work? Also, it says that I will need to put DSP cards into my system, but I have a Macbook Pro and I don't know where that goes, if it goes anywhere, so do I have to buy an external system for this? Thanks for the help in advance!
