Must say I'm a bit confused, but if you've got things working the way you like then congrats!
One thing I will mention after seeing your screenshot: I'm not sure if you've looked at the Cubase tutorial (click question mark in VC, then tutorials then Steinberg Cubase). A few pages down it says please don't use the default ports provided by the driver named "Virus TI MIDI" or "Virus TI Synth", with an explanation (timing and delay compensation) as to why.
But, if it's doing what you want it to do then....?
