Qu-sb midi scene recall?!? I am LOST!!!

Please Anyone?!?
I need your help!!!
I m completely lost with midi on Qu-sb!

I ve just receive my Qu-sb, and I m working on a setup for a performance in which I need to change in one footswitch several midi device…
I would like to move to one scene to the other by clicking once

I m using a nice midi footswitch (Soleman from SourceAudio) that could send all kind of midi data.
The footswitch is connected to my Mac and my Mac to the Qu-sb…

I ve contact Alex from the « hotline » of A&H…
We ve tried sysex and allkind of stuff…
I installed Daw Control driver…,.nothing move on the Qu

I hoped that a simple CC or even PC would be enough…but…no

I do not know sysex or NRPN…
This thing is making mad!!

Please…if anyone have ideas!!!

Thank you
