Fast Track C400 with M-Audio Keystation 49e

[soulpatch007]

Hi All -

I am a bit of an amateur when it comes to ProTools so I hope I can get rely on the collective knowledge out here on the intertubes. I am trying to use my M-Audio Keystation 49e to control the software instruments that came on ProTools SE 8.0.3. I can select the keystation as the controller, however the system makes me select something from the "Receive From" menu - the only option is the Fast Track C400. The problem is that the system appears to be thinking that the Keystation is now coming through the C400 rather than come through the USB on the computer - kind of defeating the purpose of it being a USB Keyboard Controller. Any thoughts on how I can make this work short of actually buying a MIDI cable to connect this thing to the C400?
