Good afternoon,
I set up my entire playlist in Traktor and transferred it to Rekordbox.
The transfer was simple, but the 'BeatGrid' for every track is incorrect.
This wiped out months of work :-D .
There is a solution.

That's strange, whilst there is not a lot of flexibility with Traktor NML, MIXO should set the first beat using data imported from Rekordbox.

Can you confirm they are correct in MIXO?

What file format are your tracks, MP3 or M4A etc?

Also, please make sure you chose Collection when importing:

The switch is from Traktor to Rekordbox.

Yes, I imported them as a collection; furthermore, in Rekordbox, I have to select the padlock icon to make changes to the tracks, otherwise it won't let me save them. There are over 2,000 tracks, so the process becomes complicated.

Ah my apologies. It's the same though, if the beatgrid change points are in the NML they will get imported into MIXO and exported to Rekordbox.

Do the tracks look ok in MIXO?

Also when you export you can turn off Beatgrid Lock if you want you edit them, or in Rekordbox you can select all tracks, right-click and turn off the lock.

Everything looks fine on Mixo's end; see the attached photos.

Perfect. In your Rekordbox image I can see that the beatgrid is perfectly aligned with the cue point, which is the same in MIXO and Traktor.

The difference seems to be that in Rekordbox the wave is slightly ahead.

Is this track an M4A/MP4 file?

Please can you send me this particular track and I'll do some tests.

You can upload your file here:

Good morning, The link I sent you is just a random track; this happened with 80% of them. I’m also forwarding photos of that track showing how it appears in Traktor and Rekordbox.

I’ve noticed that when re-analyzing tracks in Rekordbox, it fixes the grid, but the cue points set in Traktor remain misaligned with the grid.

Just to let you know I’m still working on this!
