It has worked OK before. The last time I used it must have been about last October. Anyway I am using AA 1.5 at the moment to finish.
When this project is finished I am ditching my Digi 002 (Digidesign drivers have always been a bodge with non Digidesign software) and moving to a MOTU 828 MkII. We have another MOTU working on a newer system and it seems to be much better integrated with Audition once you have sorted out the Win XP SP2 Firewire driver problems.
Television viewers in the UK may have seen the side of my head for a few seconds working with Audition on various of the BBC and ITV news progs today in an item about the British Film Institute.
