Help: Keylock in 4 deck mode???

Help… I am trying to get ready for using DJ Pro Ai in pro gigs, coming from Traktor. One issue that is causing me issues and preventing me from moving fully is that i can not find keylock in the 4 deck mode, which is what I use almost all the time. Am I missing something?

Hi there

Took me a while. But it is there and easy on screen in 4 deck mode.
Just click on BPM for each deck, and the musical keylock icon is there.


Thank you very much!
