LOL! Awesome. Just brilliant. Unless you are doing a 4 bar mix, you are going to need to know whether track A is playing faster than track B or vice versa - even by say .5 of a BPM. CDJ's only give you a round number for the BPM, so once it trails off tempo you will need to know in which direction, and be comfortable with both the jog wheel and the pitch controls to get it back on phase.
I was in a somewhat similar predicament, in that my only gear is a pair of 1200's and a mixer, and I was going to be playing on CDJ's for the first time. My only other experience with jog wheels was playing with a buddies Mixtrack Pro. If you're in the states, I went to Guitar Center which had a set up of CDJ 2000 / CDJ 900 and a mixer. I just asked the dude if I could bring my headphones and some tracks over to practice for a bit on an off day/time when it wasn't crowded. He said yeah, and I went to it just to familiarize myself with the controls, jog wheel, and overall feel of the unit. If not in the states, then perhaps another store that has the units that you can demo in store? That would be my best advice - you are going to want to get to know the feel of them before going on live otherwise it will be a disaster until you get the hang of 'em.
Also, depending upon the CDJ, it may be USB stick compliant. If so, you can download RekordBox for free from pioneer, analyze and organize your tracks, and then be good to go without the need to burn a ton of CD's. Just another option. That way you can input pre-programed cue points on your tracks if you already do that now, which you can't do with CD's unless you bring a SD card with that information already stored on the card (also done with rekordbox). You may even be able to use a usb stick for that as well if you already have cd's burned - but I'm no expert on the intricacies so I'll defer to others.
Assuming you aren't mentally challenged, you already know that 128 + 1.60% is 130, and + .78% is 129. To the best of the CDJ's pitch accuracy. The readout on the CDJ is just a root guide, and that's assuming it's not on a 2000, which has a tenth of a BPM display.
Of course, also not being stupid, and riding the pitch fader a bit until it's around half way through the value will get it pretty close too. If you just touch it until it flickers to 130, of course the rounding is going to screw you. The advantage is that you don't have to spend a ridiclous amount of time listening to two basslines and trying to check phase. The tracks are in time before the second one even goes in, which gives you a lot more flexibility when you're actually bringing the track in.
If you do 32 beatmix at 128 bpm it wont trainwreck if you have 127,5 nor 128.5 bpm.
cdj 2000 have .10 bpm visuals actually. (128,1 128,2, 128,3 etc)
i find the bpm meters on cdj 1000, cdj 850, 900 even 350 and ofcourse 2000 to be pretty damn accurate assuming that you play dance music.
So to answer your question OP, you could probably pick it up quite quick if you want to use them without trainwrecking although you wont learn to beatmatch in 2 hours.
When using your S4, just set the bpms with pitch fader and nudge your wheels until you can match the tracks for the time you need, thats what you can do with cdjs that reads bpm correct.
This ^^^^^^ There are no dinosaurs here professing that beatmatching is the most difficult thing, what we are saying is that it is a skill that requires a certain level of practice and conformability. The fact that you are "doing the math" to beatmatch tells me, you haven’t really mastered it, because if you’ve mastered it its more a feeling, I dont really have to calculate anything, just feel it, thats because I have learnt the skill and feel comfortable with it. Everything is relative, and us guys giving advice that he should practice first otherwise risk train wrecking are giving advice relative to what we perceive the OP's familiarity with cdj;s and beatmatching are. I started out using traktor and VCI 100, then moved onto cdj's. You have that guarantee with traktor that its in sync and wont drift... beatmatching is just as much about showing restraint than making constant pitch adjustments. Often you get a track that sometimes sound like its starting to drift but in fact its not, this is were you have to show restraint because if you start making adjustments things can get out of hand quickly, if your using traktor you will never have to worry about, it may not be something your even will be aware of because your sub conscious is telling you, that everything is in sync, its not something you have to consciously compute, this is the element I referred to previous post.
If you do go ahead and use the cdj's OP than my advice would be to use master key lock so that your wild pitch adjustments arnt so evident when things go awry.
And so the DJ-dick-measuring argument begins.
again.
Not a CDJ user myself but I'd recommend If you're going to use CDJ's to run your tracks through Rekordbox first just in case. If the venue has 2000's or 900's it will help you greatly (not sure about the rest of pio's cdj line). If not, you just wasted a few hours of your life. But in any case, make sure you take advantage of whatever rekordbox option is available like cue points and what not..
