VP-330 "Human voice" synth recreation?

Post by logix » Wed Jan 13, 2021 10:06 pm

What does it take to re-create the Roland VP-330 "human voice" sounds with a synth of some kind?
I managed to re-create the "Strings" using a Roland MKS-50 using a single sawtooth waveform and fiddling with the filter. This gave me the basic sound, but of course the thing that makes the VP-330 so special is its "ensemble" effect. So recently I bought the XILS Chor'x ensemble plugin which so far (at least to me) has the most convincing VP-330 ensemble effect. That plugin together with the simple MKS-50 tone resulted in something close enough for the strings.

I suspect the human voice sounds (Male 8, Male 4, Female 4) rely on some sort of special filter that isn't found on most regular synths, or is it just a matter of programming things right?

Multiple bandpass filters and a nice-sounding BBD chorus (preferably based around Reticon SAD1024A or Panasonic MN3005).

Thanks for the suggestion.
That XILS Chor'X plugin works for me (instead of having to buy/build a hardware variant).

Please explain about the multiple bandpass filters as I'm not familiar with them.
Is it fair to assume that it's based on a very simple sound source (i.e. a sawtooth as with the strings sound) and like you say, multiple filters after that, to shape it into the end result?

Exactly -- the VP-330 is based on some simple waveform like sawtooth or pulse-wave (I don't have the schematics around but maybe someone else does to shed some light?).

This simple waveform is filtered, using multiple resonating formants that resemble the human mouth cavity and speech apparatus.

The resulting sound is still a bit bland and not really interesting, and this where Roland's own BBD chorus comes into play.
