So the thing did not work with Traktor 2 before. There it is simply no mappings. With Virtual DJ 7 the headphone output is total shit. So I could not mix. Only with the cripple DJuiced program is the really awesome. But while only a trial version is 30min. Then you have to register. Also came with me to an absolutely by gerockter cardboard, which probably means that a single controller determines visited 20 people and has fallen again.
