RX-3 Beatgrid out of sync

what range are you using for the pitch sliders eg 6% 10% Wide etc? I find the wider you go, the less accurate the BPMs are. I set mine to as low as I need which most of the time is +/- 6%
Maybe your sliders aren't zeroing properly too? If you are having issues with two 120BPM songs staying in sync at 0 adjustment (centre indent)?
In your second paragraph you say you're using the same song on both decks but one is drifting out of sync with the other, is this with both set to the mid point (0) on the slider or just using the same BPM readout on each deck eg 126.4? This might be the issue as only having one decimal place can lead to you thinking they're both playing at the same speed but could actually be as much as one tenth of a BPM different eg 126.4 can be anywhere between 126.36 and 126.45 (or thereabouts).
I understand your frustration and there maybe something wrong with your hardware but for me beatmatching is as much about using your ears and skills as grids and tempo readouts. Good luck at the festival, play from the heart mate

Hi George!
Thanks for taking your time to write an answer. I have been researching and trying to find a solution. It seems like there are other people having this issue as well.. I found similar complaints on the forums and some youtuber videos.

The pitch sliders are set %10 and usually I like it on %6 as well as Wide is too sensitive and hard to hit the spot quickly. I am not sure if it is the sliders but I will give it a try and keep it at %6 and see if that will change anything.

The BPM is not different in the tracks because I am loading the exact same track. Also all my music is analyzed on Rekordbox and they dont have any decimals as I go thru my music carefully to adjust my beat grids and cross check BPM of the song in Beatport or other services to make sure the BPM and grids are set properly.

I just paid 3200CAD for this gear a month ago and I will be very sad if there is something wrong with the hardware. Usually companies don't want to take responsibility and do an exchange quickly.

Thanks for your good wishes mate, I will do my best!

Hi again

In your 3rd paragraph you explain that the bmps are the same because it's the same track, but unless both sliders are either at zero adjustment or at exactly the same percentage of adjustment your two decks will eventually drift out of sync as they will be playing said track at different speeds. Just a side note, they would also need to be started exactly at the same time to be truly in sync which is feat in itself and generally in my experience would require some nudging to get them in sync.
The decimals that I referred to are when you use the pitch slider, you will see the tempo (bpms) increase/decrease to a new value which are whole numbers and tenths of a BPM eg 124.6BPM. What I was trying to explain is the same 120BPM track on both decks adjusted on both decks to say 124.6 (on the readout) will most likely drift out of sync because 124.6 can actually equal anywhere between 124.56 and 124.65 so one deck might be playing at the lower end of those two figures and the other could be at the upper end of them but both would read 124.6 ie rounded up to that figure to one decimal place.
I agree that having accurate beat grids is important it won't directly address the issue you have described when it comes to playing tracks at different tempos on both decks and keeping them in sync.
A good test though would be to put the same track on both decks, set the range to the lowest option +/-6%, set both sliders to zero adjustment, start both decks at the same time (or as near as), nudge one to get them bang on then let them play and wait and see if they drift out. This should prove if there's something wildly wrong with your player but to be honest playing the same file on both decks may be an issue in itself, if you think about what it takes processing wise to keep two instances of one file from the same storage device in sync. The issue might even be down to the read speed of your storage device?
A few things there to consider, maybe have a chat to other DJs you meet about this issue?
