No, no, no. I was talking about the Volume pedal function, built around
PH1 and PH2. That's not a bug, or leakage of anything bypassed, that's a
straight, intentional implementation of a "Loudness" volume control.

I don't know if the Loudness function explains the effect you are looking for.
I just gave a hint to include this in your search.
But in general, when your harmonic content changes with pitch, you *do* look
for a fixed filter (as opposed to a tracking filter), and the Loudness filter
network falls in that category.
