Volume with midi slider!

VST Live
1

Hello, as you can see in the video, the volume is adjusted using the slider. That’s how it should be. This is my desktop PC.
I open the same file (via Google Drive) on my laptop for live (1) or on my backup laptop live (2). The volume of the Opx-pro does not respond.
Everything else works.
What could be the reason for this? All W11

Maybe you set the volume slider to “audio”?
