Sorry, I was confused (it's been a long day of travel and angst).  It wasn't
the CGS Digital Noise module, of course.  It was the CGS XOR/XNOR Logic
module.  I simply put audio signals (a sine and a saw) into the inputs,
removed the diodes from the XOR comparator output to get the full swing
output, and listened to the output, which is a +/-5V pulse wave with a
complex PWM.  It sounded a bit freaky in the simulation, but I guess I'd
have to build it to tell whether or not it was worth listening to for real.

Does this very simple circuit qualify as a "digital ring mod"?
