In CH the fader control what is selected ! so if you, like Mittacious tell, create an instrument track, and select it, the fader will control the audio volume of the instrument (as it’s an instrument track, there is no Midi fader with it) !.
If your workflow use only Midi track (like Kontakt) or the Midi Racks in Cubase, well yes there is an issue. i have them all except the Ai one, and i love these stuffs very very much ! Give it a chance !
