Leeboy , the demo i posted would appear to be an official demonstration and not some guy noodling in a shop. He also does a full demonstration of the Korg Kronos. If you look at the clip i posted you will see that there is an audience and you can see display boards for Korg Products .

This is a proper Korg demonstration.

This is what Korg is putting out to sell their product and not some guy messing about although i can easily see and hear why you might draw that conclusion.

I guess if anyone wants to know what the PA products really can do they will have to audition them themselves as Korg is doing everything it can possibly do to discourage anyone from even trying one from these demos.
