I suppose I could do that, and sum it with the original wave.  I was
hoping for a single plugin solution though...

I tried that one, and it does produce lower frequencies, but the
output reminds me of the old Atari systems.  It seems to just space
the clicks farther apart...

Hmm, I've never done anything with CSound before.  It looks a little
daunting to me, but it can't be all that hard.  Still, it's not quite
the plugin sort of thing I was looking for.

Maybe I'll try to rig something up in Om, with pitch-shifters and LP
filters summed to the original...
