Playlistss not syncing to USB using "sync manager"

Hey guys, Not sure what I’m doing wrong but if I stick a freshly formatted USB into my Mac and, using the Sync Manager, “sync” one of my crates and my playlists over, the playlists never sync and I have to drag them over manually.

Any ideas what I am missing here?

I also notice the crate I “sync” is missing one track on my USB, but I have no way to tell for sure which one it is.

Not feeling terribly confident in this tool at the moment… :man_shrugging:t2:

Any missing tracks in your collection?

Works fine at my end, all the time.

You may want to rescan your library or try the reimport track information for the entire library.

If that doesn’t work, you may need to rebuild from scratch.

If only we had a filter so we could find them easily…


I agree, this shouldn’t have to be a guessing game. If there’s something wrong with my library then the software should tell me what the problem is. Perhaps a specific track is corrupt? Maybe an error log after syncing?

If I manually drag the same crate from my library to USB all 637 tracks reportedly make it. It’s only during “sync manager” syncing that 1 is missing, and zero of my playlists sync.

My Engine library is less than a year old, I would hope it’s not corrupt already (how? doing what?) and require a complete manual rebuild. I’ll just switch to Rekordbox at that point…

With the old Denon DJ Music Manager, after syncing it would present you with a list of tracks that didn’t copy over, and why.

The artwork was too big. The bit rate was wrong. It named each track and gave you feedback.


Hmm yeah I don’t get any message or alert like this. Sync manager is still just completely ignoring my playlists though. Kind of annoying…
