Okay sly here is what i have dug up. That mixer does not have group out, or mon mix like the old behringers had.

What you could do to get only the track going out to the sound card is to run the RCA cable coming from the sound card input to either channel 1 or 2 and plug it into the insert jack. This will only go into the first click so that the insert acts as a send.

If you have a manual for it, you can see what kind of jack is required for insert. Other than that there is no way to separate out the signal from the mix.

Before i spent a few hundred on DAW software, plugins, and/or effects i would make the best investment you will ever make, A good solid audio interface. It will be the hear and soul of your system. Presonus, or Focusrite are the two i recommend. Get what you can afford, but what you want to have for a long time. I have the Audiobox 1818 VSL another good choice for those who are doing solo work is the Audiobox 22 VSL

Guitarhacker, one of the guys around here is very high on focusrite and he gets very solid results. Plugin come and go, but the interface or sound card is the foundation you record on.
