What you want is most likely a very short delay line from the second
unit with a reader of that line at the input of the first. I am fairly
certain that the delay has to be at least one audio chunk in length
(even if sc lets you specify a shorter delay, it cannot do a shorter
delay without infinite recursion issues).
