Well, it isn't quite that simple.  You want the output levels to be 
independent of the gate level, so that requires internal gate 
processing.  You also want a good curve on the release, so it reaches 
cutoff at zero after a reasonable time.  A nice example for an AR EG is 
found in Electronotes #92, p. 13.  Ian Fritz published a design that 
derived from an earlier idea by Carl Hovey in EN#31.  I would use 
different gate processing than Ian's, which is TTL based.  I am thinking 
of breadboarding this on a MUUB-4 and entering the contest.  It will be 
interesting to compare three different AR EGs on the MUUB-4, with 1, 2, 
or 4 EG circuits.
