MOTM

If not already under consideration, I strongly suggest putting in an End
Gate output socket (ie., gate goes high when Release (or Decay? maybe a
switch to select which one?) goes below some positive voltage.  I have
found this to be very useful and intergrable with other modules. If
front panel space is used up already, maybe a toggle switch to switch
between OUT- and END GATE at one socket.

If there is room, a pot (say, 0 to + 4V) to select the voltage below
which the gate goes high on the Release (or Decay?) slope would be very
nice.  [Ok, then we get into voltage control of when the gate goes
high.]

Just my $.02 to bother Paul again, Jeff
