*Anything* that could: 1) improve the poor performance of rtaudio for
Windows users; 2) offer a variety of driver models not limited to ASIO,
should be welcomed with open arms.

IMO, Csound5 for Windows is stuck in deplorable rtaudio and non-functioning
FLTK.

I'm happy to hear from Dave Phillips that Linux CS5 is doing so wonderfully
(including rt); realtime Windows users are still firmly planted in the land
of CS4.

It would not be difficult to create an MME plugin based on Csound4 code
(I think I could use rtwin32.c from 4.24.x with some changes for the
Csound5 API and reentrance). However, the question is that having a
separate MME module is really needed, or rtpa.c can be improved somehow ?

portaudio works fine in my csound5 build. There are latencies, but
nothing more than you would expect on windows. I don't know the
status of the newest CVS code. The only thing that doesn't work is
ASIO full-duplex, but that's possible to resolve, and I will do it, if
no else with more spare time than me gets there first.

I don't think we need another MME implementation. A native ASIO, possibly.
I will look into that, when I have the time.

I think the problem is with Windows systems that do not have ASIO
(or have but is not usable). If you are about to write a native
ASIO plugin, you may want to have a look at rtalsa.c and rtjack.c
to find out more about writing rtaudio plugins.
