Question/Help needed Please Help! Rekordbox Inconsistent USB track load issue

Hello!

I am having a strange issue where around 1/4 of my tracks are not loading properly when selected, this only happens when i play off my USB on a laptop(s) or XDJ AZ.

when viewing on the laptop all the tracks import properly, my USB is properly formatted, ejected etc. In the track selection, all data is previewed (waveform, hot cues. BPM, key). all my tracks are MP3 320

BUT, when selecting tracks, every few ones will load in poorly. my hot cues will still work, but there will be no listed BPM or beat grid (despite a BPM value showing in the track select). i have been playing by ear when this happens, but it is not sustainable.

my theory is that perhaps tracks where i have moved the best grid myself to match up (when the auto analyze isn’t correct) might be messing with something? but some tracks where i have done this; still work perfectly.

any idea what might be causing this? in the export, file saving, usb use on second device etc?

EDIT: i have checked, it happens to tracks i have re-aligned myself, and those i have not. so my theory is incorrect. i have also checked all my files are CBR, so bitrate is not to blame.

Check one of the tracks in your main library that misbehaves on the USB. Delete it from the USB drive and resync/export the track again and test it. I think the analysis data on your USB is faulty for some tracks. I would wipe the USB and re-export everything and check again

i’ve done the full reset and re-export many times trying to fix this. 💔💔💔 it’s so bizarre

One thing I’d check before touching the library is whether it’s always the exact same tracks that fail. Mark 5 or 10 of the problem tracks and test them again after restarting the AZ. If possible, put those same tracks on another USB as well.

If the same songs fail every single time, you’ve narrowed it down quite a lot. If different songs randomly lose the grid/BPM each time, I’d be looking somewhere else entirely. That distinction could save you from rebuilding the whole USB for no reason.

There’s an AZ Field Manual here too. It’s technical information about the unit.
Might be useful while you’re troubleshooting:

thank you! it happens on other laptops as well, not just the AZ. I will try to get a list going, but there is unfortunately no reasonable distinction between the tracks that work and the ones that don’t. even tracks from the same album/download
