A bit unrelated but I sometimes wonder what Bach would have thought of, and how he might take advantage of modern day electronic keyboards. The ability to change voices at will (even on different areas of the keyboard), and importantly for Mr. Well Tempered, the ability to change tunings with the press of a button.

Surely even these days keyboards should be sensitive to key aftertouch to get a clavichord like vibrato that Bach was fond of.

It'd be like Switched-on-Bach^10 but improvised live by a single madman on his electro-organ.
