There are a few things to look at in DP for routing MIDI data:
1. In the Preferences Menu, go to Midi Solo and Patch Thru under "Play And Record". You will have options to choose Direct Echo or Auto Channelize.
Direct Echo-- routes data from your controller to be "echoed" back out on the same channel where it was received
Auto Channelize-- MIDI data is sent from the controller to the currently record-enabled MIDI track. This is my preferred setting.
2. In DPs Setup Menu, choose Input Filter. You can select specific MIDI data to be recognized and other data to be ignored. You may also just choose Controllers: ALL to quickly activate all controllers without a lot of haggling. Later, you can edit this to recognize all controllers EXCEPT ones you specify or ONLY those controllers you want to have active. I just leave all controllers active and haven't had any problems.
Once DP is set up to recognize control data and to "auto-channelize", you should be able to reassign a specific fader, knob, or wheel to your VI console. You may need to go back to your VI Console and reassign the X-Fade slider to your desired hardware controller fader, knob or wheel.
3. As mentioned in my previous post, you may use the "Reassign Continuous Data" plugin on a mixer MIDI channel insert, or you may go to the Region Menu to choose "RCD" to the same effect.
4. In the same Region Menu, you might also want to look at "Create Continous Data", which further enables you to set up behaviors for controllers which include various details of controller sensitivity.
It's rather complex to guess why DP is not recognizing your preferred controller, but as you are working through this keep in mind that assigning the controller might be easier by just highlighting, clicking in, or activating whatever assignment button or window is dedicated to this process and then just moving your preferred fader, knob, or wheel. DP *should* see which hardware control fader/knob/wheel you want to use without a lot of numerical guesswork.
5. Do a test of your controller data communication with DP. For every fader, knob, or wheel, create a unique MIDI track. Hit record and move one fader, knob, or wheel at a time. If DP and your control device are communicating, you will be able to confirm which control number is being received from each fader, knob or wheel by checking the individual tracks. Sometimes, control surfaces are not as passive as they might appear, and certain default setups on control surfaces may be designed to override commands coming from the host software.
hope this helps
