I'll start by saying hello to the Traktor family . I recently bought a Behringer BCD 3000 , it came with a Traktor LE . I instaled the BCD3000's drivers , and the NI with Traktor LE , it works , but not entyerly , my first problem is that the headphones aren't working and the second is that the fx controls do not react , i can see them on the monitor moving while i control them but there is no reaction in the sound . Can anyone help me ? Details about my pc ... it is a desktop with windows 7 os , intel core 2 duo , with a built-in sound card (realtek hd audio) . I have a working 5.1 speaker system . And attached to it , by usb the BCD3000 .
