Problem with midi connection

hi there. I upgrad from artist 11 and am having problems with my midi controller. It’s a launchkey 37 and every time I connect it, Cubase locks up completely, until I disconnect it. I am doing something wrong? thanks greetings

Hi,

It’s strange, the launchkey MK3 series are supposed to be fully supported by Cubase 12.

Hello, I realized that the problem was in the usb since it is not 3.0… I connected it to the 3.0 port and it works fine.
thanks!
