Yer there is no need to go spend money on software with a setup like that man! However if you feel the need to use a computer, you can hook your cdjs and djm up to your laptop using ethernet cables and an ethernet hub. Then you can load tracks onto the cdjs straight from the computer, and also preview tracks in your headphones through having the mixer hooked up. You use ethernet cable to hook the cdjs, mixer and your computer up to a hub like this: Your setup would then look like this (note you can also plug your mixer into the hub) Then all you need to do is install recordbox, which can be found at - http://www.prodjnet.com/rekordbox/suppo ... ap_lang=en You can preset cues, hotcues, loops etc for tracks on there. Just an idea instead of using serato/traktor when you already have access to this!
