Bind Note with CC out to Plugin

I purchased the upgrade for Scaler 2 to 3 and it’s currently missing a KeySwitch function. They have exposed a Bind Zone parameter which means I can trigger a note key and output to the CC value. I haven’t managed to get the Binding to send a CC to the plugin. The values are limited to max of 1. And I don’t see anything in the Expression options to map to. Any suggestions?
