I'm not following your argument. First you said that it is necessary to use 
data from several contacts per key. Now you seem to be saying that it 
isn't. Actually, I have no idea what the different contacts are for. Are 
they really used to shape an attack envelope, as you seem to be suggesting 
above? For a fast attack your ear cannot distinguish different curves, and 
linear interpolation of two closures should be adequate.
