Tyros expression controllers etc. in live style play

Dan
A friend recorded some midi fles of his playing using his Tyros.
I guess he recorded directly on his tyros live.
When I inspect the midi files, the tracks on the recorded midi file are full of thousands of CC#11, 72, 84 etc. controllers to give feeling etc. to the song
When I use the same tyros styles on my VA and make a song chord, then export the song chord .
It does not have any CC#11, 72 and 84 controllers.
Also I do not think VA makes these CC# controllers in live VA style play.
Can you explain please.
