maybe, but i dont feel its overdrive doing this,,,sounds rather clean actually.
imo its either its the choice of frequencies for the bands, the Q factor isnt as narrow, or maybe not all bands are working here - from what we heard that seems most likely to me. i mean, if you ever heard a vocoder work, any vocoder, they are much more intelligible than this.
btw, vocoder is little more complex than a bandpass network. it has two stages in order to work:
first you split the modulator input signal (like voice) into bands with bandpass filters, then you place a envelope follower on each of the bands. so they practically detect sound energy per band. this is often referred to as "analysis".
second half of vocoder design is "process": you have another bandpass filter network, but this one is processing the carrier signal (like synth or a string machine), and each of the bands is followed by a VCA.
now all you have to do is feed the control voltage created by each of the envelope followers to corresponding band's vca on the carrier side. basically you are "analysing" the signal energy per band of the modulator signal, and applying this to the carrier signal.
so for a 12 band vocoder you need 2x12 bandpass filters, 12 envelope followers and 12 vcas. and some summing vca.
the sliders are VCA output levels from the carrier. you can tilt and shape overall colour. in some ways it acts similar to a graphic equaliser. with all of them up, there should be intelligibility.
interesting things happen when you have a vocoder patched out (like bode or moog or ems) then you can play arround and mix and match the envelope follower outputs to the "wrong" bands on the carrier side. staple of many old scifi.

: almost any vocoder can create such huge bass. vocoder may impart some colour depending on the bandpass filter design, but result largely depends on the choice of carrier signal - if you happen to input an outrageously hefty moog bass as your carrier, result will most certainly have big bottom
