midi footswitch to pass through to amplitube?

So I have amplitube 4 and it works great with my fbv express pedal when used in stand alone mode. I cant seem to figure out how to make cubase pass the midi through from the pedal to amplitube when I use it as a plugin. cubase sees the pedal fine if I set it up as a quick control. I’m just failing to get the last bit working. Has anyone gotten a midi foot switch to pass through to a plugin?
