How to control plugins applied to audio files with Artist Control

[ozu]

I'm using my Euphonix MC Control with Pro Tools. Even though it is the first model and the touch screen is not as responsive as Avid's Artist Control i'm very happy with it.

One thing i cannot succeed is to control audio suite plugins when applied to audio files. The knobs are working perfectly when i try to control channel plugins and i want to use it when apliying to audio files as well.

Is it not possible to control audio suite plugins when applied to audio files rather than channel plugins or am i missing something?

Thank...
