2 soundcards vs Ni Traktor
HELLO! my greetings and respects to all the people in this forum 
Does anyone knows how to configure 2 soundcards (internal+usb) in NI Traktor 3.2, in order to plug my headphones and preview monitoring the track i’m about to mix?
Thanks!

dont think you can without a lot of fiddling about and some 3rd party apps
virtaul audio cable should let you do that

is for a pc
If you’re on a mac you can make an aggregate device
I made an aggregated Device on my mac.
Was easy to do.
I have not tested it fully, but have read that it can be intermittantly dodgey.
