Beatgrid Lock
Tracks in your library can be locked to avoid accidentally changing the BPM or Beatgrid information for the file. This provides a handy visual aid for tracks in your library you feel have correct Beatgrids and BPM values.
Find a track you wish to lock, hold control + click in the empty Status column (the first column in the main Library view). A Blue Lock icon will be displayed in this field. Press control + click again on this icon to unlock the track.
TIP: You can lock several tracks at once. Highlight the track selection you want and then click in the Status column. Serato DJ Pro will then prompt you if you want to edit all the tags for these tracks.
Track Lock
If a track displays a gold lock in the Status column, then the file information for the track itself cannot be changed. You will not be able to change any of the track’s information permanently in Serato DJ.
This includes BPM, Beatgrids, waveforms, loops, cue points, or other metadata information. However, you may be able to adjust information for the track when in a session, but this information will not be saved (written) to the file’s meta tags where this information is kept.
The file may be locked because you are using the wrong formatted hard drive (i.e. a NTFS drive formatted on a Windows PC and trying to use this on a Mac which can only read this information).
Or it could be that the file itself is locked. To find out if a track is locked, highlight the track in Serato DJ Pro, and press control + R to ‘reveal’ the file location on your hard drive.
Then press either command + I (‘Get Info’ for Mac) or alt + enter (‘Properties’ for Windows). Then see if the track is Read Only, or that you have the permissions to write to the file.
