turn off BPM counter and phase meter. use your ears. Why? How does making something arbitrarily harder help anything? Ohh... For the reason that in the olden days people didn't have this ability so nobody should use it now that it is available and becoming more common and will soon be the norm. Anyway... Not the time and place for this debate. because it makes it much easier (possible) to DJ on different set-ups when perhaps you won't have traktor if you know how to use your ears rather than your eyes. makes sense no? Absolutely. But in my case the chance of playing on anything different is next to zero. And I have no aspirations of actually playing at a club etc. But yeah, if this is where you are headed it is a required skill (for now). well the OP was asking abut CDJ's and being able to go play in a club. So if that's the goal it's always going to be better to be reliant on your own ears rather than a piece of software. That will allow you to play off Vinyl, Cd's or whatever. this skill will never die. Regardless if you think it will because you don't need it.
