Change the autowah to have a cutoff range of 20Hz to 20KHz
...
This is the same as allowed in the SF2 spec for its filter cutoff generator,
which can be used for a wah effect in MIDI. It makes sense to use a similar
range here.

Still just guesses, but this seems to avoid math problems with low peak gains.

Redo the autowah effect
...
It's now a low-pass filter with a cutoff that varies according to the input
signal amplitude.
There remains issues with apparent feedback in the resonant frequency with high
resonance values. The actual cutoff range for the filter is also a guess.
