Reply to Sound card help pls

Hi,

I bought the M Audio Fast Track guitar|mic audio interface. I want to use it with traktor to practice mixing. I want to listen to both outputs on headphones but have ONLY main tune playing on speakers. Is this possible with this soundcard or not?

As you no doubt tell I am new to all this stuff so am just trying to get my head around it.

Look forward to hearing from you. Any other information required please just get in touch.

Sunny
