Soundcard Problem

[DJ Bongojoy]

How can you monitor your track on deck B while track on deck A is playing? I just buyed an 3DEX mixer and instalt the standart program. The headphones works but only when crossfader is in the middle and both deck volumes are up. Once I go to mix a track in from the deck I am cueing I have to turn the headphone button off and turn the volume down then turn around and turn it up to mix it in. Is there not a way to keep the song going in my headphones and mix it in all at the same time? I’m only using the soundcard in my computer… Do i need an ex USB Soundcard or =?

You need two sound cards or a sound card with two output channels. I am not sure if the U-Mix Control has a built in audio interface. If not you need two outputs to route your sound through.

You need 4 outputs : main L+R and headphones L+R
actually you only have 2 outputs (the main I guess).
