And I'll add a few other items:

Other CS4 versions for Windows don't work with DirectX or ASIO drivers and
thus suffer from latency issues in real time. Lacking ASIO, they don't do
multi-channel either.

As for CS5, real time audio is still problematic; in CsoundAV (in contrast
to all others) I *never* have to fool with buffer settings. In CS5 Windows,
the buffer issue is quite unclear and changing - plus seems to be different
on different platforms. Also, since only ASIO is implemented, regular
soundcard users have to install and configure ASIO4ALL. Older systems are
ruled out due to the 44100 minimum required SR (a number of my compositions
use 22050 so as to be playable on these systems).

All these issues have been discussed previously on this list, with the hope
that developers will give them some priority.

I'll also add that Gab Maldonado has been active in maintaining and
debugging CsoundAV, and personally responsive to my particular needs (i.e.,
realtime performance). IMO, for the relatively novice user, it is the most
user-friendly and tolerant Csound around. And this is important if you are
writing pieces that hopefully others will want to perform.

CsoundAV does not, and will probably never run on anything other
than Windows, making it much easier to find default buffer settings.

More details on this ?

Well, but Csound5 at least actually runs on different platforms.
And things like buffer settings are highly machine dependent.

PortAudio is not limited to ASIO, it also supports DirectSound and MME
(as well as WDM but that is experimental). You may want to ask Michael
Gogins to include a PortAudio module that is compiled to use DirectSound
in the next Windows file release.

Now if only all the efforts on maintaining the various platform specific
Csound variants derived from old versions of Csound4 would be spent on
Csound5, we would eventually get one good version instead of several
broken ones, all with their own set of bugs that have been fixed in others.
And the fact is that in recent years CsoundAV was only actively developed
in the areas of real time audio, OpenGL, and FLTK, while core language
support is still only 4.19.
