Got an FLX6 a few days ago and for whatever reason it causes my PC to lock up with Serato. I gave up trying to fix it and just installed Rekordbox. From Googling it looks like RB's key detection is a decent bit more accurate than Serato's so I was planning to reanalyzing my library with it. I have the "write the value to the id3" checked in RB's settings, but when I looked at a couple of the albums that it had scanned in tagscanner, they weren't showing the key RB found.

I'd like to figure this out before I spend 4-5 days scanning my library. If I ever get Serato working again I'd like to have the better key's from RB in my files. Anyone have a suggestion to me? I am working with ALAC files if that makes any difference.
