It's still great, I still love it, Paul should still add it, but it is called
TRIG IN not RING. OOPS!!!!!

First to Larry; the TRIG IN takes a pulse in and causes the filter to "ring
(oscillate then decay away to zero)" for a short period of time (the length of
time is proportional to the frequency of the filter) -- no input signal is
needed. The sound of it is very much like a tuned wood block being struck;
marimbaesque. I remember getting similar sounds out of the Resonant Filters
(?) on the EMu. It does not interfere with standard operation of the filter,
so you can get an extra piece of sound out of one voice.
I think your on to something Hugo (or just on something), but there is no way
I'm going to put any voltage thru a 4X amp into the filter to see what happens
with to it. The TRIG IN only sees a pulse, a non-pulse CV won't do anything.
It reacts to audio kind of like you think it might, it's essentially AM. I
think there may be some kind of "diferentiator" involved and I may try some
experiments in the near future.
