Jamie,

The shorting that sometimes causes a rim voice to fire is merely an 
ephemeral electrical artifact. Keith's version of the magic box is an 
attempt to control how the module senses a rim switch to create 
another input entirely from it. At this point, Keith's invention 
permits discrete percussive effects, but he is attempting to refine 
it so that faster successions of events on a pad via the rim function 
(that is, rolls and swells) will be possible. On its own, the module 
resists this kind of response for its rim function. My money is on 
Keith.
