Out of curiosity, I read through the manual and app notes - there's no indication that it will work at all as far as I can see - there doesn't on the face of it appear to be a Mackie emulation, which has to be the starting point for Audition controllers, I think.
Oh well, that's a shame. Although maybe that's a good thing because that takes away one source of temptation.
I have to admit I don't know the first thing about how these external controllers "talk" to Audition. I gather it's not just MIDI, because then it would be possible to use the keyboard / MIDI shortcuts. Given that the AA developers are (presumably) too busy to widen support for more controllers (though with these becoming more common, surely that would be a useful feature), I wonder if there is anything in the AA SDK to allow third parties to add support. Not that I have any spare time to code one up myself, even if I did get a controller. If there isn't, perhaps there should be. Perhaps I should be typing all this in the wish-list thread?
