you're missing the point. unrealistic is like an entire section of piano writing that has no velocitization at all, and is just the same machine-gun attacks constantly. or, it's a funk piece where the leads have no swing and are dead-steady on the beat, making it sound robotic and un-human. when you listen to a track and you think, "that sounds sequenced" - that's unrealistic. it's relatively easy to write stuff that sounds "real" with a sequencer, and that's the goal.
