I've just done a really simple little video showing Display Quantization in the Notation View.
I'm nobody's keyboard player but I was able to get a clean enough score that it could be exported as MusicXML.
My underlying MIDI performance is very, very, human (with feelings), and was not edited in
any way whatsoever (that means note positions and lengths are exactly as played).
If it works for me it will work with a good musician
