[Stk] Wah-wah filter?

[Robert Oschler]

Hello all,

I'm a veteran C++ programmer but I am brand new to the STK.  Although
somewhat math challenged I do know basic DSP principles.  Is there a
built-in effect that creates a good Wah-Wah pedal effect?  If so,
where do I start poking around to use it?  If not, are there some
low-level filter effects I can use to build one?  Or do I have to go
it alone and create a separate block of code that does the DSP
operations necessary to create the Wah effect?:  Note, need it to be
fast enough for real-time processing.

For the guitarists out there, I want to create a truly solid Wah
effect that really sounds like a mouth opening and closing around the
sound, something with some body to it, instead of an adjustable cutoff
filter that sounds more like someone simply twisting the Treble knob
on a stereo (is there some resonance processing involved with
achieving an enhanced Wah effect?).  I'm going to use the effect to
process the sound output of my current STK waveform output.
