This software has never worked properly yet. Even the basics of beat gridding do not work properly. I used to have serato before the cdj's and somehow it put a perfect grid on every track. I've been using this for three years and I still have an imperfect library. At this point I've stopped working within rekordbox and altering anything because I know it wont work in the future or I'll lose my information somehow. I tried migrating my library as a backup and that failed too....
I'd like a response about this software and what is being done to finalize it's issues. I don't even do this for a living, I do it for fun, and the fun is partially sucked out of it because of these glitches which all seem to go back to rekordbox. Not trying to tell you what to do, but I've worked in companies before. You should end your relationship with the company who makes rekordbox for you. They're really, really bad at programming.
