okay, so as you most probably know, the CDJ 400's have USB compatability, which got me thinking.. If I could find an adapter on the net somewhere, that has; 1 USB head at one end, and 2 at the other end, then could I rig up 1 hard drive to both the decks? Effectivley it would mean I would only need one music source that could be used to store all my music, and then used with both decks. Or will the CDJ's not be able to use the hardrive at the same time?
