I had tried to upgrade to the latest revision of Pro Tools a couple of weeks back but Digidesign was having some trouble with its download servers. I took the plunge last night and upgraded the system to 6.7cs2. Remarkably everything went smooth. I have read about a number of studios having trouble with this release particularly on the MIDI implementation. I won’t get a chance to test the new environment out in a production setting for a few days but my system tests last night were fine.
