Recording my mixes with Pioneer djm 800 + cdj 900 and traktor pro

Hello Everybody,

I have djm 800 + 2 x cdj900 and traktor pro 2 and i am using Mac !

I just simply want to download my mixes to my computer (Is it possible in mp3 format ? )

I am not using a soundcard etc.

Ok it's easy when you are using only traktor pro :) but when all the others are connected i can not manage to record.

Is there a simple way or should i definitely use a soundcard ?

thanks for yr help
