Yes, a digital logic delay. This is similar to a digital delay for 
audio but it is intended for logic signals. You only need one bit of 
resolution (signal is high or low), and a sampling frequency of 1 KHz 
to get millisecond resolution. You'd want to support at least 10 
seconds of delay and have multiple taps. And there's no need to 
anti-alias anything.

Consider it to be the ultimate gate delay that preserves both up and 
down transitions as well as gate sequences. If you were to input a 
sequence of gate pulses, they would come out the other end exactly as 
you put them in but delayed (by up to 10 seconds).

This module is on my "to do" list, but it could be years before I get 
around to building such a thing. Please, somebody else build it.
