That Ralph Maten demo was enlightening. He was operating the keyboard like a disco/dance machine. A few years ago I played with some fancy drum machines in the music store. They worked pretty much like the Casio in the demo. I'm sure you all noticed that Ralph was pushing buttons rather than playing keys. Today's youth are pretty good at pushing buttons. My daughter is pretty proficient with modern technology. She even gets a charge out of "pushing my buttons" on a daily basis.
God Bless,
