Check the analys method in rekordbox. It should be NORMAL. Dont use DYNAMIC.
XDJ RX Beat sync problems
Hi, I just recently got my XDJ RX, and it's a great bit of kit. The only problem I'm having is when trying to use the beat sync function, it doesn't always work that well. I used to have a paid of Numark NDX900's, which, although they had a beat counter, it wasn't all that accurate, never mind being able to beat sync, so I can beatmatch no problem, I just thought it would be fun to mess around with the beat sync function.
The problem seems to be that although the tracks have been properly analysed in rekordbox (the beat grid falls on the kick drum exactly), often it won't match up perfectly when I try to use the beat sync function. This is not a problem in itself, as I have just been using the jog wheel to make adjustments to the track I'm mixing in, to get it synced up perfectly. The issue is that it seems to try to correct itself over time, i.e. to sync itself back up with the out of sync pattern it was in before I adjusted it with the jog wheel. I would have thought that beat sync would have meant that it would maintain a steady tempo in comparison to the other track that was playing, regardless of whatever I do with the jog wheel, if that makes sense?
Also, is there any other way of adjusting the tempo than using the slider or the jog wheel? My old decks had a pitch adjust button on them, which you could speed up or slow down the track with, temporarily. I realise this might be a bit of an amateurish type of function, so it probably hasn't been included on this model. I just found it easy to judge how much the track would speed up or slow down, compared to the jog wheel, which can be a little sensitive at times, if you try to speed up a track a fair bit, to get it in sync. I can't see a button that does this, but perhaps there is another button with a dual function.
The main problem is the first thing, the second point was just me ruminating, really.
It is showing as normal now, however I think I might have changed it at some point in an attempt to get rekordbox to speed up with the analysis. It's been taking a good ten minutes per track. Is there a way to check what method it was analyzed with?
Obviously I don't want to try and reanalyze the lot at that speed! I have since deduced that it is the processor on my laptop that is the problem, it's only 1.4 GHz, the minimum recommended is 2 GHZ.
Also make sure that the grids are properly aligned on both tracks where you're mixing in and out. You may have to manually fix them in Rekordbox and then try the mix.
I have reanalysed the tracks and it's working a lot better now. Just wish I had a third or fourth deck to play with now!
Can I ask why not use dynamic analysis even though it aligns beats better than normal for some tracks? If you use normal, and have to correct your beatgrid let's say every 16 bars, ... If the beatgrid is not correct, sync is not working correct at all. So I was wondering why everyone is saying you should stick to normal analysis?

Not all tracks are created equal.
so many variations, especially older tracks
that were done analog before the digital age
I've been fighting with a track for a while because its so old, the kick and the synths are not in sync. I'm guessing the guys had no way to sync them and you can see in rekordbox that the synth gets ahead of the kick. So its hard work setting the beat grid.
I've had more than a few tracks that i had to work on yo get them right, don't give up
persistence pays off. Don't forget to set the song your mixing into as well. Set it up precisely as the track tot struggling with...it helps
