Michael,

Here's some feedback on the latest CS5 win .exe. (I've had major system
problems the last 3-4 days, and am just now back operational.)

1) Ctrl-C and Ctrl-Break are now working properly for me - as long as I
remember to select the correct window first. Somehow, on my system CS5
closes the (FLTK) performance window without selecting the "run" window.

2) Any reason, in the distribution, not to have the windows dll's in the
main folder? Otherwise you have to move them (as the .pdf says); they work
fine in the "main."

3) With regard to ASIO: unfortunately, I can't test this with my Gina card.
It seems the program doesn't accept SR's less than 44100; did you mean this?
At 44100, I can't get anything - even very cut up.

4) With regard to MME: for my sound card to put out anything even generally
chopped up, my SR (on both my Gina card and a garden-variety CompUSA stereo
card) must lower to 8000 - and I'm talking mono here. (Please see the
dirt-simple test file I've been using to test - a switched on/off 10-second
performance sine wave.)

Here a very odd thing happens: with SR=8000, if ksmps=1000 (along with -B
and -b), the actual performance is 8 seconds long (instead of 10). When
ksamps=2000, the performance lasts 4 seconds; when 500, performance 17
seconds (and interrupted/sporadic); when 100, performance 83 seconds (and
vastly distorted).

Funny thing: elapsed time, as indicated in the performance messages, is all
proportional to the time warp; i.e., the messages always indicate a
performance duration of 10 seconds.

Again, these results apply both to my Gina card and the ordinary stereo card
I have.

I've also run this file in CsoundAV. Both with ASIO and the DirectX drivers
it has, this can run at normal speeds (44100) without problems (it has a bit
more problem with MME). AV also doesn't have the SR limitation to 44100 of
CS5.

AV has got to be handling audio differently from CS5. If this has something
to do with the Csound extra buffer layer you've been talking about, for the
sake of all realtimers, let's get that out of here!

Might be good to talk with Gab to come to some idea of what the realtime
performance difference (radical) is due to. For me at least, CS5 isn't close
to being practical for realtime - even with ASIO.

Have others put the latest Win .exe through any realtime test?

Subject: [CSOUND-DEV:5224] New CsoundVST file release -- again.


> This file release is in the csoundvst package and is named
> csound5-mingw-2004-08-16.zip. It is for Csound 5 and CsoundVST with
prebuilt
> binaries for Windows built with MinGW, and sources for all platforms, and
> contains the following changes:
>
> The portaudio.dll file is now named portaudio.dll instead of
> portaudio.dll.0.0.19. It is built with Dev-C++/MinGW instead of autotools
> and contains ASIO drivers, DirectSound (DirectX) drivers, and Windows
> Multimedia Extensions (WMME) drivers.
>
> Top/main.c and InOut/pa_blocking.c contain minor changes in an effort to
> improve the ability to cancel a performance with real-time audio using
> Control-C (console Csound only). It works for me, but your mileage may
vary.
