Cubase's getting stunned! DRUM MAP.

Hi there!
I have the same issue every time i use this feature!
When i’m loading a “create a drum map from an insrument” feature in the inspector zone - my Cubase Artrist 9 is getting stunned!
Then I manually have to force a task in task manager! What’s going on, does someone had this issue?! Thnx in advance for help!


What VSTi do you use?
