[sdiy] Ensoniq patent, was: distance meter for keyboard, was: Where to get special white keys?

[Kyle Stephens]

Oops!

Well, I was looking into just this sort of thing some time back, for a velocity sensitivity retrofit of a keyboard without such (the Ensoniq patent was suggested to me too, though I hadn't any luck either finding it). I found some comparable prices, on linear sensors, not just switches, somewhere, hm.
