Description: A time-varying filter that imposes vocal formants onto the source. The filter morphs
among four selected vowel shapes, driven by a polyrhythmic combination of two LFOs, the first of
which is also tied to an auto-panner that operates on the vocalized signal.
Notes: Feeding the filter is a regenerated delay that can be used to create talking-echo effects.
I/O Characteristics: Mono-in, stereo-out.
