Using CC controllers per track on Vienna Instruments plug-in?

[MartinNew]

I'm trying to control instances of Vienna Instruments pro plugins with the CC controllers on my MIDI keyboard.

 

Inside the plugin instance, there is an option to Learn controls of Volume, Expression, Attack, etc on separate controllers, and this can be done in the stand-alone instance outside Logic X. However, I can find no way of controlling an individual track.

 

I need to use controllers as I want changes in volume and other functions to change in one track, rather than globally.
