Sync Center
How to bring playlists, cues and grids safely into your DJ software: choose a target, review the preview, decide on conflicts, write with checks.
On this page
Targets and methodsLink to “Targets and methods”
Open Prepare → Sync, via File → “Sync to” or by right-clicking a playlist → “Synchronise playlist”.
| Target | Method |
|---|---|
| Rekordbox | “Direct” into the Rekordbox 6/7 library or “XML (official)” |
| Serato | “Serato 3 · Crate” or “Serato 4 · direct” |
| Traktor | “NML” |
| Engine DJ | “Cues, loops & grids” or “Direct (m.db)” |
| VirtualDJ | “XML” |
| Pioneer USB | “USB stick” |
| More | “M3U8”, “CSV”, “HTML”, “Package with audio” |
Under “Content” you choose the whole library or a playlist. What each target reads and writes exactly is described on the pages for the individual programs.
ProcessLink to “Process”
- Choose target and method, define “Content”.
- For file targets, “Create preview”. The “CHANGE PREVIEW” marks each entry with “NEW”, “CHANGE”, “REMOVE”, “KEEP” or “CONFLICT”.
- Decide conflicts: for each entry, “Keep target” or “Take Sonodex” or “Remove from target”. With “View field changes” you see every field.
- If it says “Ready for export”, “Run checked export” writes. For direct targets, you confirm “Sync to … now” with the figures for new, changed, removed and conflicts.
At the end, Sonodex shows how many entries were transferred, unchanged or failed; “Show target in folder” opens the target.
Checking and journalLink to “Checking and journal”
- Before writing, Sonodex checks that nothing has changed since the preview; afterwards a checksum confirms the result.
- If the sync is interrupted, Sonodex restores the previous state via a journal. The copies for this only exist while writing.
- If you change anything after the preview, a new dry run is needed.
Back up before the first syncLink to “Back up before the first sync”
A finished sync writes directly to the target and cannot be undone in Sonodex; Sonodex keeps no copy of the previous state.
Close the DJ softwareLink to “Close the DJ software”
Direct targets write to the DJ software’s database. If it is still running, Sonodex aborts, for example with “Rekordbox is currently running. Quit Rekordbox completely before applying.” or “Engine DJ is running. Please quit Engine DJ completely and apply again.” Close the program completely and start the sync again.
Advanced optionsLink to “Advanced options”
- Sync mode
- “All selected tracks”, “Playlist” or “Changed since last export”
- Key notation
- “Original”, “Camelot” or “Open Key”
- CDJ profile
- CDJ-3000 or CDJ-2000NXS2 (USB)
- Reconcile target
- “Merge · keep existing entries” or “Full · check removals”
- Path mappings
- “Apply path mappings in export”; you create the mappings in the library tools under “Paths”, for example when the music on the target is on a different drive. The first matching mapping in the list applies.
- Field mapping
- Transfer custom tags, energy, rating and notes to “Comments” or “Grouping”, or “Do not transfer”
- Colour mapping
- “Cue palette (RGB, comma-separated)”, only for Rekordbox XML
- Exclusions
- Playlist names, folder names or path prefixes and custom tags. You can also exclude individual playlists with “Exclude from sync”.
Protect target gridsLink to “Protect target grids”
“Protect target grids” (on by default) leaves the beatgrids in the DJ software unchanged. Only turn it off if you deliberately want to write the grids you corrected in Sonodex to the target.
