[Sharing c'est cool] Pedagogic Poly Synth

Hi !
I'm sending for the first time a Pedagogic Patch for Basic Snthesis (create for my courses). I hope you find it interesting !!
The document, the instructions is in French, sorry, to hard for me to translate all in English :-(
You will see some patches, abstractions and functions used by the community and at the MaxMSP tutorial. THANKS all the people that share their skills, knowledge. !!!

Here's my "little" contribution.

I know (and imagine) that it can be developpe 100 times better. The idea is that you can do it and used it
f.e. : ( http://www.104.fr/#fr/Artistes/A190-Laurent_Ajina )
My questions are :

How I can use more voices without having problem with the CPU limit?

Exist an object (probably Ejies lib ?) to draw enveloppes in 3D ? or in jitter?

What others treatments I can used in this patch, any suggestions?

There is also a "bonus" patch where Gizmo~is use JUST 4Fun

A très bientôt

PS: You must have CNAMT lib and Peter Elsea Objects (I think is all....)
