A short addendum to my previous post...
trigger on 20v falling edges, the Random Voltage Generator would not
work, because a new random voltage would not get sampled when the
rising Smooth output reached the sampled voltage (causing CUPL, which
is patched to SAMPLE, to go from 10v to -10v).
So I think we can assume that Stepped SAMPLE was simply designed to
fire on large falling edges, so that the RVG patch would work, and not
on small falling edges, so that ordinary pulses give the expected
behavior. Mystery solved!
