Hello everyone
Recently I've bought 2x cdj900 nexus. However, I noticed something terrible. Tell me if I am doing something wrong.
I mix house / deep house music, so '4 to the floor' mostly. I do not use the sync function. Here is the story:
I play a track from PLAYER 1. Let's say 122 BPM. I load a track into PLAYER 2. Set it 122 BPM as well. I press the 4-beat loop button, I match it perfectly by ear with the track from PLAYER 1. It's playing there muted, looped, 4 beats, perfectly matched. As the track from PLAYER 1 reaches its last 32 or 16 bars, I release the loop from PLAYER 2. However, by this time, it is already de-synchronised, the kicks are off by milliseconds. Every single time. Now my question is, what am I doing wrong? It is okay only when I press the sync button, but when I leave a perfectly matched loop and a song playing together, it desyncs over time.
Do I need a faster USB stick? Or is it normal? I am confused, please help.

Although your display shows 122 and the tracks may be in sync within the loop, is it only the act of exiting the loop which causes the two decks to come out of alignment -- and if so, do they regain alignment and stay in alignment if you nudge it back with the jog? Or does it continue to drift?
Have you run your tracks through rekordbox?
Yes my tracks are ran through rekordbox, beatgrid perfect, with sync on everything is on point.
When the tracks are playing together with no loop on one of the sides, it's perfectly matched till the end of the tracks. Only when one side is looped, say 4-beat loop on player 1, and the other isn't, the players start to come out of alignment. More and more as the time goes on, after 2 minutes it's almost a train. When I nudge them back in alingment, it happens again after a while. I noticed that to set a track to i.e. 122BPM, the tempo can go to i.e. -3.25%, however moving it slighty will result in -3.20%, but the tempo stays the same (122.0BPM). I checked in both cases, and that is not the reason as well.
So I gather from that statement then that the loop itself is imperfect as it would either be too short or too long to stay in perfect alignment with the other deck (non-looped). Are you using the quantization?
yes, I am using the quantize function. It says 'quantize' on the screen. I create the loop by pressing the 4-beat loop button. Happens also when I make it longer to 8, or shorter to 2. Doesn't matter. It looks to me like the software takes some extra delay in miliseconds to actually loop a part of the track or something. But then again, when I press sync, it can go in alingment for a whole day.
Just now, I changed the tempo for both sides to 100 BPM, so really slow, and it didn't happen. After moving back to normal tempo, it started to happen again.
