Thanking you for the app you created, I expose my problem to which I can’t find a solution.
I use the three main software: Traktor, Rekordbox and Serato.
My workflow is as follows Traktor → Lexicon → Rekordbox and Serato.
When some tracks slow down, a second beatgrid point is imposed on traktor.
Thanks for reporting that, I’ll have to check it out with your track and library.
Can you upload your Lexicon database & logs? From the Help menu.
And upload that track in the screenshot? You can upload here: http://upload.lexicondj.com
If you use the beta and you have imported from Traktor again (disable the Merge option to start fresh in Lexicon), then you should not get the beatshift anymore when syncing to RB. At least for the tracks you sent me
