Track changes
Added and removed tracks are listed separately, so backup differences no longer depend on memory.
For rekordbox USB drives
Back up and repair
USB libraries.
USB still works on your CDJ or XDJ, but rekordbox says the library is corrupted? LastCUE scans the USB first so you can preview recoverable tracks, playlists, and CUE points before deciding whether to repair. One-click backups also keep a history of library changes. Library processing stays local on your computer.
- Back up your library in one click
- See exactly what changed each time
- Preview damage before repair
- No previous backup required
- Library processing stays local
- Your library and audio are never uploaded
One-click backup
Tap CUE to back up the library on your USB.
If the library is damaged later, local backups can help you restore or roll back.
Stored locally LastCUE stores backups on your computer and does not upload library data. Current backups focus on the library database and related data; they do not include a complete backup of every audio file.
Change details After backup, review the details for each CUE: track changes and playlist changes are clear at a glance.
See exactly what changed between backups.
After every CUE backup, LastCUE compares it with the previous backup and separates library changes into three readable views.
Playlist changes
New, deleted, and renamed playlists are surfaced on their own, so USB organization stays traceable.
Playlist content updates
Added or removed tracks inside each playlist are shown line by line, making every change easy to locate.
One-click repair
Repair “Device library is corrupted”
Preview tracks, playlists, and CUE first, then safely restore the library
When a library is corrupted
A corrupted rekordbox library may not need to be wiped and re-exported.
If the data is still on the USB, LastCUE reads what remains and builds a repair candidate you can preview. Check which tracks, playlists, and CUE points are recoverable before deciding whether to continue.
Potentially recoverable
The USB still works on a CDJ or XDJ, but rekordbox reports a corrupted library. That usually means some data remains, so you can start with a free diagnosis of the recoverable scope.
Not recoverable
export.pdb was deleted, or the audio files themselves are missing. LastCUE cannot recover data that is no longer present.
Preview for free first
Diagnose the source and review the recoverable scope first. If you continue, you then enter the paid repair flow; unsupported sources do not consume a repair credit.
Tools
Tools will keep growing with ongoing updates.
Check what this device supports first. Convert incompatible audio before showtime—not after it fails to play.
Convert incompatible USB audio to a tested compatible format.
Convert to MP3 128 kbps, MP3 320 kbps, or WAV while preserving library information and CUE points. LastCUE backs up first, then checks the converted files and library references.
01
Choose a compatible target format Choose MP3 128, MP3 320, or WAV based on capacity, sound quality, and player requirements.
02
Carry over CUE points The conversion carries over the source track's CUE points, with no reorganization or manual cueing required.
03
Update the USB library directly After conversion, LastCUE updates the matching files and library references, then checks the write result.
