| The sources for *_export and *_input are in all the source
distributions; there are in csound_src.zip and in Csound.tar.gz on the
elusive bath server.
BTW I have been offered a new server locally which is not subject to
quite so many nasties. I am testing it at present but it seems much
faster that the current one. More news later.

Subject: Re: [Csnd] Win NT Problems take 2
OK, I have tried this on v3.58 under Win2000, and there is indeed a
little problem.
The function to play sound at end is sndPlaySound(), and it is set to
SND_ASYNC. This means the function returns immediately after the call.
However, if 'Remain Active' is set, Winsound effectively relaunches,
killing the audio.
The quick fix is just to use SND_SYNC instead (as I find I did in
v3.55):
sndPlaySound(theApp.GetProfileString(csound_section, "Soundfile",""),
SND_SYNC);
So Winsound will wait for the sound to finish before restarting.
Presumably this applies also to v3.59; I will install this ere long and
investigate.

Subject: [Csnd] Administrivia
James Andrews and I have completed out tests and so we have
transferred the csound mailing list from Exeter to Bath. A forwarding
address has been left in Exeter, but the main submission address is
now
csound@lists.bath.ac.uk
Sending mail to csound-help@lists.bath.ac.uk should give further
instructions on how to use this list.
I have reinstated the [Csnd] prefix as it seems to have more support
than not, and I have (re)added the short trailer to say how to
unsubscribe.
At present the digest remains as before, but I am actively
investigating how to integrate it. I am actually creating digests
inside ezmlm but no one is getting them. I hope this will be a simple
system and largely automatic, as it has been for some other lists ran
from lists.bath.ac.uk
If you have any comments or suggestions for improvement send them to
me and I will see what I can do.

Subject: [Csnd] Real-time Keykit->Csound working on Linux
Hi, I just thought I should mention that I have Keykit working with
Csound (real-time) on Linux. I did this by driving csound with Line
events, rather than MIDI. Unfortunately this means that without some
additional work, my Csound output is not really integrated into KeyKit
in the sense that MIDI is.
But if anyone else would like to try this, get in touch and I could
share some KeyKit code.
(note: this message has been posted to both the Csound and KeyKit lists)

Thought I would try out this list and see if it works. I just got the

It is sort of amplitude modulation based.

Subject: Re: [Csnd] Csound stdin / stdout
The reason I'm asking about this is if it worked as advertized, it would be
possible to write a VST plugin or a JavaSound implementation of Csound by
reading and writing audio from the Csound process file handles, instead of
having to hack the Csound code into a new kind of driver. This would only
work if either input, or output, or both, blocked if data were not
available.

I never tested it. Do you have some suggestion?

Hi John,
We have found the following problem here at Glasgow Univ:
Using WinNT, on an NTFS partition, system drive is D:, the majority
of the file system (including the csound program dir, and the root
dir) is write protected...
... the first time you do a compile, it works ok, but the second
time you try, csound reports that it cannot write the score.srt
file. If you re-import the .sco and .orc files into the interface
(although it looks like they are already there, of course) it will
work a second time, but you have to do this each time you compile.
Nasty, and most people have gone back to the command line.
I suspect the search path within winsound gets reset after you run
a score. Most people would not see this problem as not many people
write-protect their systems.
We'd be very grateful if you could fix this. It's probably a very
simple bug.
Thanks,
Stephen Brandon
