About documentation, i would mention the first part of the Rob Hordijk page about vosim :
https://electro-music.com/nm_classic/015_workshops/Clavia/NordModularWorkshops&Threads/WerkMap/WorkShops/Hordijk1999-2000/VOSIM.html
which describe well what is done for the windowed sync part.


then for each algo, the comment of the voice.ccp should do :

ALG29 :

Osc 1 synced by 3


                     IM3
                    <----
             .---.         .---.

             '---'         '---'
             |IM1           |IM2
             .---.          .---.
             |*1 |          | 2 |
             '---'          '---'
             |Mix1          |Mix2

OK i clean up a little as localEnv were not used anymore in getNextBlockWithFeedbackAndEnveloppe.
Let me know if it's OK for you.
If yes can you "approve" the PR. I'll then know it's good for you.

Thanks

Hello Xavier,
i answered about Osc.h in the PR : it's about a small cpu optimization..

I thought there were a problem.
I looked again and it looks good. Thanks  :)

About the phase reset, yes why not using the master osc phase, it should sound a bit better, thanks !

Another small change :
i removed the bias in the sigma filter as it don't bring anything significant and can possibly cause click
