[sdiy] fatar keyboards

[Carsten Tönsmann]

Hi Dave,

I built a MIDI keyboard interface for a Fatar keyboard.

These keyboards (as mine) usually have two so called rubber contacts per 
key. These contacts have a dynamic resistance depending on key pressure, so 
if you analyse the resistance you get two informations: A key is pressed and 
how much is the pressure. This enables you to create control voltages 
depending on the key pressed AND depending on your dynamic play.

The second contact per key enables you to determine the the key velocity as 
the reciprocal value of the time between the contacts closing, another 
dynamic information.
