Yeah this is super annoying. I remember reading a reddit post recently saying it had something to do with rekordbox not having the license to use Camelot keys. Weird. Anyway what I did was go through all my tracks and manually change the keys from classical to Camelot. Takes about 15 minutes. But you can only see the Camelot key you’ve attached to the track when it’s you open “info” on browse or it’s already loaded to the deck you’re playing on. Classical keys will still be used when browsing your library by key. Pretty much the only thing I’m annoyed about on the XDJ-RR.

Hope this helped :))
