It's really makes difference for whom the show was perform (after all it's not a video demo, it's just recorder presentation).

But still when You compare show performed by Michel Voncken, and this video here, they are miles away.

Anyway, both Michel and Bert (along with some others like Thomas Berlin) really makes excellent presentations (at least in form of video-demo), and everyone who looked at some of their presentations immediately had this feeling: "I got to have this keyboard, it's fantastic".
