Who said Buchlas trigger on the falling edge of a trigger? A 281 has a
switch to select between AD and AR responses. What's happening when
that switch is thrown is that the level is being shifted so that the
input comparator is responding to either the 10 volt spike at the
beginning or the 5 volt gate (with duration). The length of the spike
at the beginning of a Buchla pulse is very short, but that really has
no bearing on the speed of the triggering. I would worry more about
the Serge sending out 5 volt gates. With those, you should be unable
to use the AR mode on the 281.
