Suki, I understand your point, and if look at all the demoes at web,
you'll find a lot made by Yamaha that is more advanced demoes.
Those that Baartman does are also often 'deeper' than the one above.
Again, if look at the public in the video, mostly well grown up and older people.
They hardly tap feet to the music. They is probably there because of free coffee,
softdrinks and some 'schlager' entertainment, not because they want deep
technical info about advanced features.
I think Baartmans demoes and this one are done for different usergroups.

Btw, I did not pay $6k either, far less, but still not the cheapest I ever bought ......
