Ken - maybe you already stated this somewhere, but how close does the
CAPS AutoWah come?  Maybe it's possible to swap out it's filter with
another implementation?  Or raise the upper limit on the Q parameter?

Being a bass player, I've always wanted an AutoFilter plugin
(envelope-controlled LPF).  If I get time, I'll start with the CAPS
AutoWah and replace the bandpass with a lowpass.
