Well, I sort of got off on a different "track" here, ( no pun intended ). The varying voltages transmitted by the rheostat would, of course, correspond to the different leverages established by the sliding weight/contact, as the lever pressed on the key. These then would be sent directly into a computer with a program to interpret them ( I'll leave that part to one of you brainy types to figure out! Sarah???) The big problem, as I percieve it, would be preventing drag from the wires interfeing in any way with the measurements. An old, high quality stereo tone arm with adjustable counterbalances might be a good model to use, to avid this. Or a radio transmitter? Have a nice day.
