hello everyone. Can someone please help me. i bought my DDM4000 Behringer mixer about a month ago and have been tryiing to learn and map the mixer. i have a generic sound card. the problem i am having is how in the world do you map virtual dj 7 pro to my mixer. i am a beginner at this. Is there anyone that will have the patience to tell me the ABC's on how to do this. i purchased a general midi usb cable. just has in and out on one end and usb on the other end. Thank you very much in advanced for your help.
