Cubase switching VST to GM Mode half way through export.


Wondering if someone could give me a hand figuring this out. I am audio exporting some midi files using halion sonic. Half way through the audio export i get a window that comes up asking do i want to change to gm mode?

Is there anyway of stopping this happening. Ive used the logical editor to remove program info but it doesn’t seem to work for this gm switch?
