The registration memory buttons need to be back underneath the screen. This one issue has hampered what I can do significantly on the Tyros 4. No sliders needed. They do double duty with the existing buttons.

Having a Music Finder feature as is done on the Korg's Songbook. Especially, to be able to hook up an ipad or laptop and use apps like unreal book to pull up the lead sheet and set up the keyboard all at once.
