I also use Key matching when mixing.... the key codes show in the track listing.... but the co-responding keys do not light up anymore.. can someone help. ?
Looking at your screenshot you have Master selected. Think it only works in Auto?
I'm having the same issues, and I've bounced between Auto and Master.
Having the KEYs colored really helped with quickly registering if things matched up before in previous versions of Traktor. I'm a very visual person and when I'm DJ'n, seeing the colors helps be quickly select if something may be a good fit, especially if I'm doing something on the fly and I have less than 30 seconds to switch things up.
Check to see if your settings have inadvertently changed.
In Browser Details --> Key Reference setting, I have mine set to Deck Focus. That is working for me. When I choose Master Deck the key colors do not work.
Sometimes if you toggle settings back and forth, that can get them to work.
Good luck. I hope this helps.
Thanks for the screenshot. Reviving this post to point out that neither of your decks are the Master. The key match function works off of whichever deck is the Master.
I had this trouble once. Check out that preferences>external sync>external clock source is set to EXT, not LINK.
