Using EQ with external audio interface (Just like the filter)

In my studio I use a 3rd party audio interface to route all 4 decks to an analog knob mixer. It works great because I can still use my controller (DDJ SX) for the filter and FX.

BUT the EQs do not work in the same manor. Everything but the EQ routes to the interface. Not sure why but its a little hanidacp to my set up.

I use to use Traktor this way (Sorry) and it worked great. But I don't want Traktor I want REKORDBOX.

Thanks for listening.
