SourceRaver Posted August 1, 2012 Share Posted August 1, 2012 Ok…what the heck is ‘pitch resolution’ and how does it affect my beat matching?When you move the pitch slider on an older Technics turntable, the pitch is infinitely variable. That’s means tiny movements of the pitch slider result in tiny changes to the speed of the platter and vice versa. It’s a proportional relationship where when one variable changes, the other changes accordingly.It doesn’t happen this way with CDjs or controllers.Because of their digital nature, the pitch can only be changed in set increments. The size of the increments is the pitch resolution (think of it like the steps of a staircase). The higher the pitch resolution, the bigger the increments. What this means is that when you mix two tunes together with slightly different BPMs, you may never get them to match exactly as your media player will only ever play them at a set speed. The result is that nicely overlapping beats will always drift apart. A lower resolution is better as it has more increments and you are more likely to get the bpm’s to match. Your mixes can be longer in duration before the beats to drift. Below are some figures for some Pioneer CDjs:CDJ800 +/- 10% with a resolution of 0.05%+/- 100% with a resolution of 0.5%CDJ2000 +/- 6% with a resolution of 0.02% +/- 10% with a resolution of 0.05% +/- 16% with a resolution of 0.05% +/- 100% with a resolution of 0.5%It’s definitely something worth thinking about before you buy your next CDJ or controller/software.

Mitch Posted August 1, 2012 Share Posted August 1, 2012 The mathematical side of me picked this up the day i started DJing. Great post to break it down for everyone Quote Link to comment Share on other sites More sharing options...
GREMM1S Posted August 1, 2012 Share Posted August 1, 2012 Have noticed this before, of course nothing a small nudge of the jog cant fix, not enough to outweigh all the benefits of cdjs but still a consideration. I actually noticed doing a mixtape once where i was really trying to nail the perfect transitions, if some tracks it was impossible to get them 100% matched Quote Link to comment Share on other sites More sharing options...
mattus123 Posted August 2, 2012 Share Posted August 2, 2012 great post source, im sure alot of people wouldt have realised thison the CDJs you can often choose between which pitch increments you use, i rarely take it off .03 Quote Link to comment Share on other sites More sharing options...
SolDios Posted August 2, 2012 Share Posted August 2, 2012 So that means when I nudge the pitch up a tiny bit and the percentage doesn't change, it hasn't done anything? Quote Link to comment Share on other sites More sharing options...

MelodyIlliterate Posted August 2, 2012 Share Posted August 2, 2012 Is this the same as bpm readings saying 128.xx vs 128.x ? Quote Link to comment Share on other sites More sharing options...
MelodyIlliterate Posted August 2, 2012 Share Posted August 2, 2012 So that means when I nudge the pitch up a tiny bit and the percentage doesn't change, it hasn't done anything?fkn hate that. Move pitch a mil, nothing changes, half a mill more, jumps up by half a bpm :/*minor over exaggeration Quote Link to comment Share on other sites More sharing options...
GREMM1S Posted August 7, 2012 Share Posted August 7, 2012 ah that was handy to know actually, i assumed it still changed the pitch but just doesnt show it until it reaches the next 0.05.the bpm readings are irrelevant you should never trust them on cdjs anyway just a rough guide.

Once that changes then the song is affected by the new percentage. Quote Link to comment Share on other sites More sharing options...
