All of a sudden I have volume control and panning issues with Halion Sonic 3.2.10 and HS SE 3.2.15.
They don't work, but no crashes with BIAB. ... it worked before, and you can set volume etc in the Halion VST's GUI itself.

This happens not only in BIAB, but also with Cubase. I wonder if this is a windows issue maybe.
Other GM plugins work fine, like Coyote BTW. Any finds from HS users?

I posted about this on the Steinberg forum, but no reply yet. F
