Recording with CDJs and External Mixer

I'm sure I was able to do this years ago before I sold my CDJs.

Now I have them again I can't fiqure out how to record my mixes with my CDJs and external mixer.

I can use my setup to play with Traktor in HID mode - I just can't get anything to record.

Is this possible without Audio 10?

I'm using a Mac this time - was on Windows before, if this makes a difference.
