VP330 human voice

[jhaible]

Hi,

I hope you have a nice Christmas !

I have just finished the filter bank of the Roland Vocoder Plus
"Human Voice" section.

I haven't built the divider circuit, nor the chorus section. So I tested
with
a 1-VCO /w vibrato sound from the OB-8 and my clone of the JX3P chorus.
It really sounds impressive. (And I thought my Lambda was good in choir
sounds already !)

The VP330 has special waveforms to feed the filter bank: The 8' is an
exponential saw wave, and the 4' is a truncated expo saw wave. I couldn't
exactly duplicate this yet. But I got good results with slightly
LP-filtered
saw wave and pulse wave with 1/4 ... 1/5 pulse width. (quite critical. More
narrow, or broader pw's sound bad.)
