I'm not sure where to find that, can you please be more specific, I can say I know each track is set to 'usb1 out L + R'
I think i just found what you were talking about, In the config it has usb audio mode set to '3out/no input' and surround output 'out 1 L+R'
Here I did one better, here is a short video of what my setting are. Quick screen cap.

And my best bit of info is that audio does come out of the virus outputs to a mixer, but I want the audio to get through my sound card, which isn't working anymore. But its actually sending all the audio through the virus, including any audio I didnt make from the virus such as a standard loop i may load up from logic pro, plays out through the virus.
