Very nice.

Can you explain why "pseudo"?

React less on spammers and start doing some homework ;)
Or, react less in general and do some MORE homework :)

VOSIM (VOice SIMulation) sound synthesis is based on the idea that by employing repeating tone-burst signals of variable pulse duration and variable delay, a sound output of high linguistic and musical expressive power can be obtained. Conventional means such as oscillator and filter banks were therefore entirely dispensed with, basically simpler apparatus being used instead: two tone-burst generators and a mixer. Starting with these rudiments, the aim is an optimal representation of the input data and a progressive application of logical calculus to the sound-synthesis process.(http://www.atiam.ircam.fr/wp-content/up ... _VOSIM.pdf)

2 of my teachers, Dr. Werner Kaegi(http://en.wikipedia.org/wiki/Werner_Kaegi_(composer)) and Stan Templelaars(http://trove.nla.gov.au/work/15984099?selectedversion=NBD12833504) developed this synthesis technique to create a simple way to produce a simple vocal simulation based on glottal pulses with formant characteristics. Called "Pulse-traines", bursts of squared sine pulses followed by silence.

In short, a kind of sync to produce strong "formants". If you can create the human voice, it is also possible/easy to create acoustic instrument like sounds.

This patch can be played by keyboard. I made a change. I deleted the RND Lfo and replaced the module by a 2nd Env Gen.
'pseudo' because vosim is a computer aided technique, not modular synthesis.
