Take a look at 'Love letters in the sand' on the same channel and you'll see him looking at his laptop waiting for it to begin the MIDI or MP3 file. Take a look also at the right hand fingering on the KN7000. . . Sometimes it doesn't correspond with the notes being played especially when there is some glissendo on them. I don't see him using the pitch bend wheel.

The upper keyboard playing looks real though.
