Does the 1884 use a Mackie Control Emulation mode or does it have a native Audition plugin(cv2)?
Frugal
It uses Mackie Emulation. Adobe have, however, just brought out a new SDK to help developers of cv2 plugins for AA3.
I didn't get far with the previous versions of the sdk that spoke to previous versions of AA, and had to re-write some C++ code to make them work at all. One problem was that I was familiar with Borland C++, and had to move to Microsoft C++ for this. Recently someone else discovered that the sdk doesn't work for us in VC++ debug mode, which is where I had got stuck. The last problem was caused by my attempting to work in Vista, and failing to make Visual C++ 2005 work correctly under that OS.
When I get time, I plan to try again with the new sdk under XP, and perhaps under Vista but using the new Visual C++ version.
I don't give up easily, so I still welcome contact from anyone else with C++ skills and an interest in this.
