>>hello, just back to the list after an absence of about a year. and
wondering-
does the jupiter 8 or memorymoog have a preset or capability for the vox
humana sound, or do they have formant style double resonant filters?or any
other investment polysynth, for that matter?<<

The polymoog synthesizer has a 3 filter resonator section for such purposes.
I once had the opportunity to patch up my polymoog mellotron male choir
sound on a polymoog that was sitting right next to a real mellotron about
20+ years ago.  The overall timbre was quite close.  As somebody there
pointed out, if it were thrown into a mix, it might pass as a real
mellotron.

As for the vox humana preset on the polymoog keyboard, that never sounded
very convincing to me.  For years I thought that sound in Gary Numan's main
hit were strings.

The synths you mentioned will generally only give very poor synthetic
imitations.  Mark Smart's page gives some better information, which is the
typical 3 bandpass filter method.  Though he gives one lower formant, and
two higher, while others give two lower and one higher.  It just goes to
show you that 4 bandpass filters are better still.  Or a whole vocoder style
fixed filter bank.  Or several methods combined including the above plus EQ
and secret programming techniques.  The reason I mention all this is by
coincidence I'm currently working synthesized vocal sounds.

Following are a couple of mp3 examples of some preliminary work.  Normally I
wasn't going to post any more audio files to this list, but the dotcom list
was just shut down.  So all those with the typical hair trigger response to
name any synth sound cheesy if it doesn't sound like a synth can refrain
from listening and move on.

Heavenly female voice without vibrato synthesized on the motm modular
synthesizer ontop of a recording of a real string orchestra and a couple of
Doepfer synthesized male bass voices.  Best if heard through high quality
headphones.

Full male/female Tomita mellotron like chorus, some voices Doepfer, some
MOTM.  The individual voices were clearer before all being combined.  I'm
still working on better clarity and realism.
