Hopefully, when you say no moving parts, you aren't referring to the keyboard.

I haven't given as much thought to these ideas. I think that some of them, like the ipad and bluetooth are very innovative. I thought about the ipad thing, actually.

Two things come to mind. You will still need buttons on the controlling keyboard. I wouldn't want to be dependent on a touchscreen for all of my needs.

Maybe, instead of an ipad, a long oblong touchscreen - either part of the keyboard or separate, where you could move buttons and functions to suit your needs. Maybe even a registration could call up a different display.

I think that these companies like Ketron and Yamaha put enormous A&R into the styles, and if everything becomes software, it will be like mp3's where only 1 in 10 actually purchase it and the rest is illegally shared and stolen. I think that this consideration will be a factor as arrangers possibly merge with tablets in the future.
