"If I listen to a demo I want to hear THE KEYBOARD as it's supposed to sound programed by the company"

I'm not sure I follow your logic. Who says the way the "factory" programs any keyboard is the way it is supposed to sound. When I play Tyros3 for friends or myself I have the settings set for what I think sounds best. Doesn't any performer make his instrument sound its best for his audience? I've always thought any programmable keyboard is just a blank page that the user fills in. Anything the factory sets as default is just a template or starting point. There are to many individual tastes for the players likes and dislikes, keyboard location, acoustics, sound systems ect for there to be a pre-programmed "best" setting. Maybe where Yamaha set up it's settings, what you hear is what they thought was best. Maybe not even that much thought even went into anything................
I don't think Yamaha's demo players did anything wrong by using the settings they did. They made their product sound its best. I think that's what their job is........It would be nice if they shared those settings though. It might be fun to load theirs and go further!! -charley
