As you wrote, the ‘vowels’ are being created by a number of bandpass filters...then the resonance controls the peaks as usual, and the cutoff changes the overall relative initial settings of each bandpass.

Understanding the Vowel Filter

The Vowel Filter didn't appear in any of my patches, since I do not understand what it does.

* An individual vowel emphasizes certain frequencies across the spectrum, which can be expressed by a set of band pass filters at fixed frequencies but different widths (aka »Q«). Great.
* The Vowel Filter allows to select from up to 5 Vowels, setting the according band pass filters. Great.
* Only one of the selected Vowel Bands can be active at a time, controlled (respectively cross faded) by the Cross Fade parameter. Great.
* Without the Cutoff and Resonance parameters set to reasonable values, modulating the X-fade parameter will not show the expected result. Head scratch.

So my question is: What do the cutoff and resonance parameter do concerning the Vowel filter?
