not shure ,,need more info ,,as to system spec ,,,,do the other functions work ,,for that side ,,, look in preferences and open MIDI tab and check that the online icon flashes while you are operating the functioning controls vs the controls that dont work,,,by the way what version is the controller pro or pro 2,,if its pro choose one of the alternative mappings for the unit and see if the same occures,, gonna need info as to what you have tried and whats going on to help you sort it out

my bad ,,U-Mix Control and Cross DJ le ,, no alternative mappings

i think if there is try that ,
