Recording from Traktor into Live 9

Recording from Traktor into Live 9

Trying to figure out the proper routing from TSP to Live 9 so I can record scratch cuts for a mix. I use the audio 8 with an external mixer and 2 turntables. I’ve tried using different outputs on the mixer routed back into the laptop’s sound card routed into live but I get a crazy delay. I’m sure there is a better way but i’m lost at the moment.

I would like to do this without a second external sound card.

MAC / PC?
How have you got it set up at the moment?
Etc.
