The Ketron SD 7 keyboard has a touchscreen and note that the icons are large, making it easy to touch the correct one.
In answer to the person who has a Ipad, they have protective
glass screens. I have one on my Ipad and never, ever have to wipe the screen of fingerprints.
I have had Wersi keyboards with touchscreen and they worked fine,even the earlier small ones. It's the future so get with the program. Lloyd
