Halion Drum Player and Cubase 10.5 automation


Attempted to use Cubase 10.5 automation for Start/Stop of Halion Drum Player.

After drawing in automation, it wont work until I press the space bar. Then my cubase project stops. Then when I press it space bar again the project starts and the drum player stops.

I have to delete start/stop automation In cubase.

Now I have to press play in Cubase and play in Drum player in order to continue with my project.
Follow transport, like in Groove agent, would be very useful here (or record midi out like in Flex phraser)

Mayby theres something i’m missing? Mayby its a bug? Any ideas?
