You'll need to insert it as a general controller, and then use the learn modes. I don't know this controller, but I do know the 428, and it's easy to set up.
Spot, did you succeed on controlling all automable track fx with your tascam?
Some of the guys in our Vegas-forum said only the few track levels (volume, pan und video level) would work.
Only volume, pan, masters work, no access to plugs, no. Never tried video level. While this feature will be cool for some folks, it's not something I'm into. (never tried it with the Tascam, in other words)
Correct. The Generic driver does not expose the ability to control Audio FX plugins or their parameters. Only a driver developed for a specific device like our Mackie driver will support this.
