@Marian > The engineers have enquired of the following:
You imported a m3u file created with traktor into an old version of rekordbox(ex. 1.5.3)?
If yes, version 2.0.3 creates a large wave-form when exportation of such songs occur.
In this case, the analysis status (percentage) will appear.
But, this operation does not change beatgrid. Is this what you reported? If yes, the beatgrid in the flash should be the same as in your collection.
If this isn't correct, please provide with as much information as possible about the procedure.
