What yet another software sound synthesis system is up to these days (below)....

It's obvious that all serious SWSS, within a year or so, will have fairly robust multi-core scalability. 

Those I know about so far: 

Max/MSP   multi-threading in poly~                  in stable production
Csound    multi-threading of instrument instances   experimental
CLM       multi-threading of unit generator calls?  experimental

Does anyone know the status of others? SuperCollider? Nyquist? Pure Data?

I do not know as much about commercial digital audio workstations, but I know that they use threads internally, so it makes sense that they either already are, or soon will be, multi-threading plugin instances and track processing. 

Cubase has been multi-threaded and multi-core for a long time, but some plugins have problems running multi-core.

Regards,
Mike
