Take at look at "Five Lectures" (http://www.speech.kth.se/music/5_lectures/) There is a very easily understood timing chart of what happens when a key is played at various levels. This was done with micro-switches and demonstrates what "power saturation" is. If you wanted to isolate the key's compliance from the rest of the action, it would be very easy to do with this approach.
