Hey, I have been running a Numark Total Control for about 6 months and was ready to buy my first sound card. I picked the DJ I/O (spare me the shame) and just got it in the mail today. When I configured Traktor 3 LE's preferences to output sound with my DJ I/O and not the internal sound source the tracks that I played became distorted and the controller's response become sluggish. Initially I thought that the problem was the DJ I/O, but found that when I restart Traktor and removed the sound card the problems remained. This issue is the Numark USB Soundcard setting on Tracktor, not the soundcard itself. Do I need a new DJ software? Is there a download that can fix this? Will I have to buy Traktor Pro just to do cueing? God I need help!
