I like to have BOTH...Touch screen for setup, configuration, programming styles, AND ESPECIALLY for entering text.. I hate that multi-button push deal with Yamaha to enter text, BUT buttons for most playing situatons as if your moving FAST..buttons are better than touch screen.
That's unless we get a 10" -15" touch screen some day. :-)
Like I use on my manufacturing systems I design, program & sell.
