Reply to VCI Audio won't split.

Using a MacBook Pro OS 10.6.8
Using Traktor 2.6.0
Using a Standard VCI-400

Hey guys, when I connect up my VCI-400 and set up the following settings... http://help.vestax.co.jp/en/detail.p...d_page_url=355... All I get is just the Audio through the headphones. I'm trying to split the main sound through the MBP's Audio line, so I can connect my speakers & the cueing sound through the headphones.

I know this is a noob question, but I don't need a sound card in order to do that? Or do I? 1 of the reasons I got the VCI-400 was because I was told I didn't.

Have been trying all possible changes and configurations for days now. Starting to get slightly frustrated. Lol.

Help me keep my cool and please help :-)

Thanks in advance.
