BPM issues when mixing with USB's (pg. 2)

The 400 might just have less accurate BPM calculation of course... if they round the number too much during the calculation, its readout could actually be way out. It's only displayed to 1 bpm anyway which isn't exactly accurate.
I'm not sure why you keep stating that specifically on the +/-10% range it should go up 1 bpm at +0.4% - the relationship between tempo and % change shouldn't (theoretically) have anything to do with the pitch range. 130 bpm +0.4% should always be about 130.5 bpm, on 6% range, 8% range, 10% range, 50% range or 100% range... but larger ranges may suffer from greater inaccuracies. |

I never get this problem with CD's, get accurate readings on both players, tracks that are the same BPM, change together at the same rate on both players.
I'm ticked off because even when tracks have gone through rekordbox, two versions of the same track that are exactly 128 BPM (only an example here) NOT 128.75, NOT 128.50, 128, on the CDJ-400 the BPM goes up by one (estimate, I know its only 128.5 at 0.40%) but on the CDJ-900 that same track, that is exactly 128 BPM goes changes at 0.35%, so I have to put it on 0.40% for the tracks to stay beatmatched. |

What are your pitch range settings for each unit? If one is set to ± 6 and the other is set to ±10/16/100, you're going to see some discrepancies.
Pitch resolutions are 0.02 at 6%, 0.05 for 10%/16% and 0.5% for 100%, as on the CDJ-1000 and CDJ-2000.

They are both are ±10. And I know its 0.05 for 10%/16%. Thats fine.
With that out of the way. Anything that is under 130 BPM will get the reader on CDJ-900 to show it increased by 1 (as an estimate I know) at 0.40% Increased by 2 at 1.15% (on the CDJ-400 this happens at 1.20%)
If its 130-142 the reader shows its gone 1 up (as an estimate I know)at 0.35%.
I know theres calculations to it and what not, I should depend on my ear and not what the reader says, but its unreliable with USB's. |

| I can't find anything that accounts for that discrepancy, anywhere. It seems like the difference should be related to a setting on one of the units or the type of file you're using for playback - something - but if you're playing two songs off of two different CD's that are at the same tempo, and still getting the same weird results, I don't know what to tell you. |

I can't get any help from Pioneer either.
Heres an example, a 129 BPM tune, just did this few minutes ago, at ±10 it went to 130 on the counter at 0.35%. (CDJ-900)
On the CDJ-400 it went to 130 on the reader at 0.40%.
This means if I actually want them to stay beatmatched, I have to have both of them on 0.35% or 0.40%. does not sound like a problem right?
But this gets tedious when I want to mix tunes that have 2-3 BPM difference give or take. But thats not the bbiggest problem either, small difference, easy to pitch bend for the transition period.
But when mixing the likes of house or any music that has long breaks without kickdrums in its intro then a kickdrum suddenly, THEN this is a problem. |

use ears not counters.
put tape on the display to hide it.
practice.
profit. |

I know how to beatmatch two tunes, when they are both the same BPM it takes a matter of seconds for me to mix them. As I already said, even if its not accurate or there a slight difference as the situation is now, I can pitch bend the faster tunes and its all fine. But this is a huge issue with tunes that have no kickdrum after their break.
When I have the technology there for me that I've paid for, I should expect no less. |

you could buy some skill:p
I can't imagine what you would do if you started learning 15 years ago.
no offense man, but you just sound like you need to practice more...or use autosync:p |

That's wrong. 129 needs to be pitched up by around 0.8% to get to 130bpm. The counter is obviously unreliable, either at detecting the original BPM or calculating any changes. Try downloading Mixmeister's free BPM analyser (http://www.mixmeister.com/bpmanalyzer/bpmanalyzer.asp) and running your tracks through it. Compare with what your decks are telling you and report back. |

or you could just ride the pitch until it sounds right.
DJ = not rocket science.
the more you look at numbers on a display, the less time you have to worry about the music. technology is awesome , but I hate it because it makes hacks that don't want to actually learn how to work on the fly feel special.
pussies! |

There shouldn't be anything wrong with the 400s. I have two, they work fine in standalone mode and with Serato. If they are faulty, get them fixed.
Jay is right anyway, don't rely heavily on BPM counters. Use your ears and adjust as you go. Ride the pitch. |
