- “Import” individual playlists from the USB to the laptops internal library (in rekordbox)
- Now you can “export collection” as an XML file
- import xml into engine - this should show the new playlists
- you can then build the stems
- when that’s done you can now export the stems back on to the USB via engine export
- You should end up with both tracks and stems working properly on the denons
