How do I control Guitar Rig as insert via midi?


I have a Scarbee Clavinet routed to Guitar Rig.I want to be able to control the Wah-Wah pedal in Guitar Rig via midi and a foot controller.
Does anybody know a elegant solution to this situation?
The situation is that the midi send to the instrument reach the Clavinet but doesn’t reach the Guitar Rig. :frowning:

This might help…

I saw the post but didn’t believed that it could be that awkward:
Anyway thanks!
