I'm new to Arturia KeyLab 61 Essential.  My Logic MainStage 3, Mojave 10.14.2,  will not recognize it. 
Ive downloaded the Arturia Software Center, installed KeyLab Essential 61 and MIDI Control Center.  .
1.  My Logic MainStage MIDI window up top is not active.  USB connection is good, though.    Garageband app responds though. 
2. Also, I cannot get Analog Lab to respond in the keyboards window. Yes, I have selected KeyLab Essential in Analog Lab DropDown I can change sounds in the Analog Lab 3 window on my laptop; the sound names then change in keyboard window, but I cannot select onboard or make any changes on the KeyLab itself..
What am I missing with these two issues?
