Donny,

This guy is performing his music for a live audience. He is not demonstrating the Tyros as such although at times he does a bit of that on the side. He has films galore on youtube and is pretty well-known in Yamaha circles here in Holland. He is, to the best of my knowledge, not a professional entertainer but a very capable one all the same. Apart from the Tyros 4 he shares one other thing with guys such as Peter Baartmans, Michel Voncken and Bert Smorenburg...........he is DUTCH !!!
.........and they know all about arranger keyboards....
