VCA's won't mute from Eucon controller.

Cubase
,
1

HOW TO REPRODUCE:

  1. Create some audio tracks
  2. Select the tracks and add a VCA fader
  3. Mute the VCA fader from a Eucon controller (in my case, an Avid S3)

PROBLEM: The audio tracks do not get muted.

If I mute the VCA with the mouse, everything works as expected. It is only if I mute the VCA from the control surface that I have this issue.

This issue is new in Cubase 9. It has always worked fine with previous versions.

Can anyone else please confirm this?
