hi there guys, i have been using the various versions of logic over the years and i have been very impressed with the new logic pro, but i am about to start university and they are running pro tools. i have no prior experience with pro tools but i have been told its easy to use. now the problem is this... i have a fairly simple set up at home involving a dual input sound card, mac book pro and a set of speakers. now when i was reading the reviews on pro tools it was stating i needed specific sound cards etc etc. now my question is this, can i use pro tools HD without any sound card or mixer or is one definately required? any feedback would be much appreciated. thanks is advance
