Reply to Denon Mc3000 Traktor mapping, help

Just bought the Denon Mc3000 and trakto 2.5 pro.

On the set up I matched it with the Denon Mc3000 and everything was fine, decks A and B work as intended and what not. However, I don't believe all the keys are mapped. Like, when I want to put a track on deck C and D, the play/pause button doesn't work, but the low mid hi filter etc works fine. I'm guessing this is a mapping issue?


Also, how do the effects work in traktor? Do I have to set them up? If so, how do I do this? My effects are not working at all, I press fx on 1 with group settings, and when I turn on an individual effect nothing happens.
