hey, i have about 7k tracks in my library in Serato and a bunch of crates which i update regularly with new tracks. after updating my crates i always safe my Serato library to lexicon and export them to Rekordbox (there are the old ones) and import the new rekordbox xml of the playlists.
When i do this and want to sync my usb for updating it, it removes like 6500 of the tracks first and readds them afterwards instead of only add like 40 Tracks in the playlist.
What can i do in order not to always delete my whole usb?? its taking ages to sync…
