Midi volume fader not working with Steven Slate SSD4

I had the State tech on the phone today for about an hour. Using SSSD Platinum drums as a VST instrument I found out that the panning and midi volume are non-functional. Haven’t had this happen on any of my instruments, virtual or not. Slate thinks it’s a Cubase problem and while we were talking he found many
complaints on the Web of others having the same problem. I might have to start a support ticket unless one the the Steinberg dudes sees this and chimes in.
