Master/Slave in Deck 1234

Hi, how come I can not see the master / slave selector?

Hi Maumaumau, Could you please give us a little more information regarding the query so we can assist. Thanks J

OP probably means sync.

No physical sync buttons on the Prime4 so it has to be done on screen.

Sure there are - long narrow buttons right above the cue buttons.

Had to zoom in but I stand corrected!
