Has anyone gotten the Osmose pressure to modify the VCA level on the Super 6?

I’m using Osmose firmware version 2.0.15 and Super 6 Desktop firmware version 1.3, but I can’t get the latter to respond to the pressure from the former to modify the VCA level. I was able to do it once, but I can’t reproduce it now. I can control things like the filter with pressure, but not the VCA level.

Is there anyone out there who has consistently gotten this to work and could walk me through the process, step by step?
