I agree it would be best for Windows to have both MME and DirectX drivers
(as well as ASIO) through Portaudio.

Actually, I thought *you* (Istvan) were doing it through Portaudio, but I'm
woefully ignorant of the technical end of things. Sorry about that.

To summarize why I see the need for other (Windows) driver models in Csound5
(through Portaudio):

ASIO is not available on soundcards other than multi-channel. Where it is
available (on multichannel systems) it is often limited to 44100 sr and
higher.

ASIO4ALL, while solving the stereo sound card dilemma, is limited to 44100
and up.

With the all-to-frequent limitation to 44100 and up, less than fairly
powerful, recent systems are often incapable of realtime audio. MME and
DirectX would go a long way toward making realtime Csound works performable
on older computers, particularly where (as in my case) low latency is not
much of an issue.

>From this line of thought it is easy to see why I favor CsoundAV - which
supports all three driver models, with good low latency *and* does
multi-channel. (I guess we shouldn't forget FLTK and MIDI too.) It's
currently the only Windows Csound that does all this, and I'm looking for
that day when Csound5 can as well - *plus* have the advantage of being
cross-platform.
