hi , i have the same problem as bobsterz , my keylab essential 61 worked perfectly with analog lab 4 , ableton and uvi workstation ,
today however , none of those seems to be connected with it , i tried different midi channels different preset in the midi control center nothing , the midi control center midi console shows that midi input are indeed recognize ,the keys , the sliders pots everything , so how is it than none of the software mention above seems to pick up any input while being on the same midi channel with the inputs clearly working in the midi center ,i did a factory reset , just to make sure i updated all the software through arturia software management app , im lost
oh last thing my korg monologue is working flawlessly with all the software mention above and vcv rack through usb midi so can't be windows or midi drivers
very last thing , after i tested the korg monologue in every app while writing this message , i tried plugin the keylab with analogue lab but not with the midi center open , and it worked
, apparently no other app can be open while the arturia midi control center is open , problem solved for me
