[sdiy] Dual comparator with a twist

[Tim Parkhurst]

Very nice idea, Peter! Along the same lines, I was thinking that it might be
useful to put a comparator (with a panel mounted 'threshold' or 'trigger
level' control) on the front end of my AD/AR envelope generator (prolly be
useful on any EG actually). Then you could cascade as many of the little
buggers as you liked.

Might also be neat to use your circuit with audio signals. Maybe the input
could be a saw and the output could be the sync to another VCO. Then you
could adjust the phase of the sync signal.
