Articulation Lane Dynamics Control Issue

I’ve been having rather regular issues with the Articulation Lane … today it’s the Dynamics Control with Halion 7/HSO. I have several patches that respond well but this Trombone doesn’t respond at all. You notice that the Halion keyboard mod wheel doesn’t move despite the FF change. Video → HSO

The Dynamics Control is set to CC 1.

But I don’t get anything…

The patch responds correctly using the MIDI keyboard mod wheel.

Note Expression Bypass

I don’t recall hitting it, but I must have.
