I've seen couple of Bert's presentations of Yamaha synths, and this must be the worst he made.

Sure he has specific sense of humor (comment from one of his presentations: "all you need now is some beat, something like umphhh, umphhh, umphhh, and You gonna get lot of money"), but this wasn't humor, this was totaly ironic.

If I didn't knew he was Yamaha employee, I would have thought he worked for Roland or Korg.

Performing keyboard, and lurking arround boringly while intro is playing to me doesn't look funy, I more see it as: "look at this toy keyboard, you don't have to play it, it play by itself, it's not instrument, it's a toy".

It was definitely not a good idea that synth guy demoes arranger, because you could clearly see his (negative) attitude toward arranger keyboards.
