Unless you want to emulate mouth-based dynamic spectral modulation, I think we ought to think differently about formant filters and there is nothing intrinsically wrong with them. If you aren't modulating them much, they are an excellent spectral shaping tool. Traditional pipe organs, and several acoustic instruments are designed to shape the sound-producing part (flue or reed, for intance) using a mouth-like cavity, as well as the main resonator (pipe or other). The "mouth" in almost all cases (there are notable exceptions in some baroque organ registers) does not change shape according to the note's envelope, so the mouth is purely used to shape the static timbre. But you do get very beautiful timbres this way, that you wouldn't get by a simple LP/BD/N/HP filter. A good example is the Chinese erhu violin.

Is this the vactrol or OTA version of the Morphing Filter Bank?
