Reply to Question: Pre-listening with Traktor pro 2.0.3

Hey guys!

So I am using a Hercules RMX mixer with Traktor pro 2.0.3 and I am trying to prelisten to the songs i want to play. Basically, what I want to do, and I saw my friend doing it, is:
Put a song in a deck, play it, and put the crossfader completely to its side, so it only plays this song.
Charge a song in another deck, and listen to it in my earphones, not in the speakers, so if i want to make a transition I know exactly what is playing on the other song!
In audio setup, I have Audio device: built in (speakers of my computer)
For Output routing: Internal
Output monitor L: Output L
R: Output R
Output master and Output record everything is on "Not connected"

Thank you in advance for your help!

PS: The earphones are plugged to my Hercules RMX mixer
