That's why I said to use the regular outputs not the gate out! With a zero
rise time the leading edge is fast enough to trigger the input of the other
half of the USG without having to mess with an inverter for the gate!

True, it isn't as steep as the gate but from looking at it on a scope it is
fast enough that I doubt it would matter for things like enveloping. I
certainly can't hear a difference even at really high rates. Others
applications this might become critical. Using the gate and an inverter
"strictly" is more correct but I think you generally can save patching by
using the pulse generated from the outputs rather than needing the gate
without loosing anything as the rise time is sufficiently fast.
