Hi Suntower,
“What I want is a FAST way to take a MIDI event I create in a song, save it 'somewhere’ (I assume MediaBay) so I can re-use it as needed in -any- CPR.”
I don’t have exactly what you want, but since Cubase 8 at least, there is the ability to import/export any track from any project - File/Import/Tracks from Project. This makes any project a library of tracks. This way there is no need to even save stuff. It is easy too.
