Can't Get TI To Respond To Midi CC Messages

[empirepd]

I am having some trouble. I have a Virus TI and I want to send some basic MIDI controller messages to the TI from Digital Performer while it is playing, but the TI doesn't respond to them. In particular, I have been trying to send Continuous Controller #10 (pan) to the TI, but it does not pan the patch as it plays. I have also tried CC #07 (volume), but that does nothing as well. What am I doing wrong? I can't believe that the TI would not have the Standard MIDI Continuous Controller messages implemented in it. I have looked through the manual, but no luck.

HELP!!!!

Thanks,
Sam
