Midi String / Comment Macro / Resolume

Hello ! i'm using HOG 4 PC and resolume one the same computer. I would like to know if it's possible to use the Midi string comment macro to launch Video clip in Resolume ? (I'll use the LoopBe1 driver to loop the ouput midi of the hog to the input midi of resolume)

And what could be the exact syntax of this comment macro ? is it better to use CC or midi note ?

Thanks a lot !
