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
