if not and you choose Pioneer CDJ in audio setting instead of the aggregated device it only uses 1 of the CDJ's as sound card.
Smart man! (Ok, I am guessing about the man bit, but Smart person! would have sounded really weird as would Smart man m/f :-) )
I usually name my aggregate totally different for the exact reason of lowering the chance of confusion.
The one flaw I see with that is that if are effectively using only one audio driver, you would be getting sound out of one player only too, right?
