Not that I am necessarily recommending it but, Csound will allow you to
instantiate multiple instances of objects at runtime. I did this with
Csound awhile ago and haven't touched Csound since but the general idea
was create all your instruments to accept parameters and store
input/output connections etc. in tables. You tell Csound to read its
score file from stdin and you create/destroy instruments with various
parameters by sending to Csound's stdin using the general-purpose
computer language of your choice. (I used Python). Hopefully Csound has
graduated to allowing instances of instruments to be created through OSC
as well as stdin at this point.

I'm working on an open source multiuser game with a sound experimentation focus.
The choosen sound engine is our favorite one Pure Data. Let's imagine populate
a 3D world with pd sound patchs !
The issue is to create/destroy audio abstractions (made by users/artists) and
connect/disconnect them.
The audio path system must be compliant with paths in a 3D world. A sound pass
through rooms and apertures :

It must be dynamic like a game. I was enjoying doing this with pd, but ... my
hair become more and more white.
It's quite difficult.
I propose here to write a little review of this issue. To be completed, to be
rectified.
Don't forget that the best is the easiest way (less compilation, less
dependancies, less bad tricks, etc.) and cross-platform (Linux/MacOSX/Win).

4 - PURE DATA - LIBPD
---------------------
Let's come back with Pd. We know that Pd was used in a game Spore :
http://lists.puredata.info/pipermail/pd-list/2007-11/056212.html
It could be a solution to handle dynamic audio patching. Any feedbacks ?
Libpd turns Pd into an embeddable library, so you can use Pd as a sound engine
in mobile phone apps, games, web pages, and art projects
http://puredata.info/community/projects/software/libpd/
libpd will make a complete instance of Pd available inside of another
application, but it does not deal with instantiating single objects. This is
still only possible with the "usual" mechanism Pd offers, i.e. dynamic
patching, and it has the same disadvantages.
Maybe LuaAV would be worth a look, too?
Ciao
