I think if one was to take a MIDI note on as noteon for ch* 
distance_from_rim velocity. Same three bytes used now but note number 
becomes position. Note off becomes important again as the length of time a 
hand (or whatever) is still touching the skin. Adding lots of program 
change or cc messages for rim was hit too, percentage rim/skin. pitchbend 
would still work for things like tunable drums.

I think PC as now would be before the hit, but unlike some synths would 
not effect any sound now in progress.... or maybe it would. In any case 
looking at any one drum as it's own instrument rather than seeing "drums" 
as an instrument (channel 10 in case we forgot) would go a long way to 
making better sounding drum synths. Basically there are three kinds of 
events in a drum performance:
State - things that are set up before a hit - PC
Hit - timing happens here - strength of hit and position of hit
Modifyers - things that affect the sound all the time but might change in 
real time.

Anyway, just idle thoughts. A real project would take a lot more time and 
energy and playing around... but it would be better than channel 10.
