I need help with my Numark N4 mapping. I can´t even map the LED´s. I don´t know the Midi Range. For exapmle, I want to map the play/pause buttons. I´ve set the controller range from 0 to 1 and from 0 to 0. Nothing worked. The play and pause button got two colours... I think cause its a 4deck controller... I don´t know exactlly how to set the midi range.
