hmmm, only a small number of analog keyboards have a trig output since many
manufacturers who needed a trigger just derive one from the incoming gate.

That said one of the complaints about the current Buchla 200e regarding cv interfacing
with other brands is Buchla's use of a very short duration 10v trigger dropping to a 5v gate
because other analog gear has trouble generating it. But then again I don't think Buchla
users are using that trig directly on the Low Pass Gate, mostly it controls the function
generator (= ASR envelopes)

So your experimental goal is to generate a very short duration control voltage event, say
+5v, right

Though I'm thinking you might want to try a VCA after the resonating filter to come closer
to a Buchla kind of sound that I guess you want since a Buchla is frequently using a
lowpass filter and a vca-like processor in tandem, but since both are vactrol you have
some lag in their response.

I would have thought a minimum attack and decay sustain and release from an A-140 set
to "L" ought to be sufficiently short.

Perhaps amping up an audio spike might be usable But one needs to be a bit careful not
to go too far with too hot signals
