les,
i just posted a quick demo of the a104 formant filter.

about the filter.. i enjoy its subtlety (when compared to most
filters). it is excellent for emphasizing multiple harmonics within
a signal, granted the signal has enough of harmonic content to
be moved around.

about the demo.. the demo patch is vco -> a113-> a104 -> vca
(modulated by adsr to provide 8th note taps). the only parameter
adjusted during the demo is the freq of each filter within the
a104, opened one at a time from the closed position, with each
landing on a different harmonic. all res knobs at full (no self res)
and all input/output controls at full.

i'm a big fan of this filter..

let me know if there is a more specific demo you'd like to hear, i'll
do what i can to record and post it..
