OK, how about this then? ;)

You can take the output of the first section in the USG into the VC of
itself and set the VC control all the way left and set to modify the rise
time. This will still create a fast enough rising edge to trigger the input
section of the other half of the USG. Adjust the rise time on the first half
to taste as you would with the inverter. The VC adjustment makes the rise
time an extremely rounded squared off wave. This allows for long attack
times except in cases where very long attack times are needed.

Inverters? We don't need no stinking inverters!
