He makes it look so easy ....

Could come in handy for quick Styles for recording originals. For those times when you don't need all the other stuff that Styles offer like intros, endings, and breaks. I know making a complete Style would be much more involved, but this little trick could come in handy, and might get folks like me started on making and editing Styles. I think it was done to show some of what the keyboard is capable of.
