Cues and Beatgrids misaligned after sync back to Rekordbox

Lexicon version: 1.8.5
Operating system: Mac 15.5

Bug description: After migrating my Rekordbox library to a new storage location (external SSD), importing to LXC and back, cue points and beatgrids are now slightly misaligned in Rekordbox. This happened after importing the updated library into Lexicon, making metadata and path corrections there (e.g. fixing artist/title tags, removing duplicates, updating file paths), and then syncing it back to Rekordbox. The Beatshift Fixer tool did not correct the misalignments. I tried Analyze → Round BPM → Quantize Cues → Quantize Beatgrid for single tracks, but the issue remains.

If I compare the same tracks exported to a USB stick earlier, they still have the correct cues and grids - so I know my original cues were fine. The issue seems to have been introduced after processing in Lexicon and syncing back.

Step by step to reproduce:

  1. In Rekordbox 7.1.2, relocate your entire library to a new storage location (e.g., external drive)
  2. In Lexicon, import the updated Rekordbox library
  3. Perform metadata cleanup (fix artist/title tags, fetch album art, delete duplicates)
  4. Manually fix broken paths so Lexicon correctly links all files to the new location
  5. Sync the collection back to Rekordbox
  6. Open Rekordbox: cues and beatgrids are now slightly off (despite having been correct before)
  7. Try using Beatshift Fixer for the entire library: no visible improvement

Just changing the location should not change the grids :thinking: Beatshift only occurs when going from one DJ app to another, or when changing filetypes (eg going from MP3 to WAV).

Did this happen on all your tracks? If so, you could fix it in bulk with the Shift Cues recipe.

Thanks for the reply!

It didn’t happen on all tracks, and I did much more than just change the location (see previous message) - I just don’t know exactly when it happened. I only noticed it later.

This is terrible, I have over 10,000 tracks :sob:

Sorry I don’t know how it happened with all those steps… :confused: Maybe you can re-analyze them? Either in Lexicon or in the DJ app you prefer for beatgrid analysis. You can always quantize cues again once the grid is correct.
