Wavelab MCU Remote device setup


I’m facing problems while trying to setup an MCU controller (SSL Matrix DAW control with Cubase/Nuendo standard map) in Wavelab 8.
I’ve properly assigned the midi in and out port and flagged the “Active” flag.
Wavelab still doesn’t recognize any controller.
How can I setup an MCU compatible map in the Remote device settings?
I can’t find any resource in the Steinberg website.

Any help?

Thank you
