I've heard that the new pro tools systems won't have it compulsory to use at least one HD audio I/O. can any one confirm this? is this just a rumour? i'm planning to purchase the HD2 system and was thinking of getting the Prism ADA Dream. Now if this is true, then i'd like to run only the Prisms. Also - is it possible for me to run the system without the digidesign sync I/O? i was thinking of using the rosendahl nanosyncs instead.
