MC8 w Quad Cortex CC#47 "mode" configuration

Hi All, I am struggling to program the Quad Cortex “Mode” fonction (CC#47) on the MorningStar MC8 to get it work propely … It is a 3 modes fonction (preset/scene/stomp) and I can program the MC8 only for 2 … I am not very easy going with all that Midi thing (will even say, that it is really the first time I approach it). Thanks for your help.
