Wow, sorry, i though it works like AsioX driver (that works effectively with the 2 soundcards)
Well, but that don't solve my problem.
Even with my SB, how to make it works with Traktor? Is there a tutorial?
How to plug? Y-jack (one to headphone, and one to hi-fi)? which output port?
It's the first i try to do this (and i think you see it

)
thx
