Cubase 8 Elements Assign MIDI to a VST Instrument Track?

I would like a VST instrument on a given instrument track to respect the MIDI channel set for it in it’s inspector. I have read about the Input Transformer for doing something like this but then I see that on the VST Instrument Track there’s a selector right there to choose a MIDI channel for the track, and another for the port…yet it always plays regardless of what MIDI channel my MIDI controller keyboard transmits on. Although page 212 of the manual states the following, I see no such thing as an “Input Transformer” as described here:

“Pre (Filters/Gain) (Cubase Elements only). Contains input filter and gain controls along with Phase and Gain controls for audio-related channels or an Input Transformer control for MIDI channels.”

I feel like I’m missing something.
