I wanted to share with everyone the solution to the problem I was running into with connecting Amplitube to Digital Performer. I contacted Amplitube, read through the entire manual, and tried every recommended approach to no avail.
I finally contacted MOTU tech support. I got a prompt reply. Here is what they said, "MIDI Learn is pretty straight forward in DP. In the plugin, click the MIDI learn icon in the bottom left corner. It's the icon directly to the right of the camera icon. After you press it, click on the Wah parameter in the plugin. Then, move your MIDI controller knob or pedal. If DP is receiving MIDI signal from the controller or pedal, it should lock right up to it."
The advice was correct, however, where were the camera and learn icons? I couldn't see them at all on the plugin. I almost gave up and then noticed two of the smallest icons I have ever seen on the very edge of the plugin. As the MOTU tech later informed me, "They are part of the DP plugin wrapper. You will see them on all plugins in DP." Actually, they are part of the "Effects Window." Now that I found the "DP midi learn icon" I followed the advice I was given and everything works fine now.
The tech also gave me the following documentation on this - "Check out page 891 of the manual:

So, there you have it. Hope that is of help to others!
