By the way, I forgot to mention that my example below requires a DC
coupled ring modulator, so it will not work with the A114, though it
works with a PAIA 9710. It might also work with the Doepfer A-133
Polarizer, though I don't have this module yet and haven't tried
it. If anybody has a 133 one and feels like trying the patch,
please let me know if it works.
