Yep, the jack code does not work yet...  I would not even expect it to
compile.  I might get it working by the next release (which is in a couple
of weeks).

[Osw-users] more problems with cvs version

[smoerk <sm...@gm...>]

hi,

i compiled it with alsa support and now cannot start it. does cvs 
version only work with tcl 8.4? i have 8.3.5 installed, which worked 
with osw 1.1beta3.

i forgot to mention that it crashes on linux easily with all 
help_*Noise.osw patches. :) maybe i try to write a better bug report the 
next days. for now i need some beers after two days of crashing open 
sound worlds...

about the latency, i didn't measure the raw audio latency, this is the 
latency i get when i touch a slider, switch on audio, etc. it could be a 
slow gui, which causes this. i have to test it with external triggers, 
for example OSC commands.

the 1000ms latency i experienced on my windows machine is surely a 
problem with my sound card (rme digi96/8). the rme support wrote me that 
directsound is supported by this card. so i'm waiting for the asio 
drivers to test it again on windows (or another machine with a consumer 
aound card).

Re: [Osw-users] Boo!

[Amar <am...@pt...>]

Strange about the binary rpm, I'll look into that.
The Jack drivers are part of the source code, but I do not believe they have
yet been fully implemented.  In the meantime, the ALSA interface is the
preferred one.

ASIO is being debugged, it will be a separate "add-on" when released.

To everyone: I am generally perlexed at the recent experiences of 100ms or
1-2s latencies under Linux and Windows, as well as some of the crashes.    I
do not see these issues on my systems - variability is not surprising
though.  Open source projects rely on their user communities to help track
down such issues and make improvements.  To that end, detailed bug reports
either to this list or via the SourceForge bug-tracking system are very
welcome.  On a similar note, more volunteers to test the Windows installer
and Linux rpms prior to each release would be very helpful.

[Osw-users] Boo!

[smoerk <sm...@gm...>]

i had to rebuild the rpm from the source rpm and now osw starts. it 
seems that the rpm from osw.sf.net does not work with redhat 9.

after my system froze imediately when clicking the speaker symbol i 
tried i compiled it with --enable-jack. i suspect this is not officially 
supported as i couldn't get any sound out of it, only got this "Boo!" 
messages on the terminal, although it connects to jackd and the osw 
ports are available.

then i tried again with alsa. it crashes when running as root, but works 
when running as a normal user. latency is not very low, but much better 
than on my windows install. i guess around 100ms in comparision to 1-2 
seconds on my windows (it's on the same machine!).



when will the asio drivers for windows be available?

Re: [Osw-users] about Max/msp

[Amar <am...@pt...>]

Hi,
  OpenSound Control is a protocol for communicating between different =
software applications and devices.  It includes a hierarchical address =
system (e.g., addressing elements of a synthesizer or app using =
URL-style names) and arbitrary data types (ints, strings, floats, =
whatever) and can run on various high-bandwidth transport mechanisms, =
such as UDP-over-Ethernet.  More information can be found at =
http://www.cnmat.berkeley.edu/OSC

  Several applications support OpenSound Control, including Max/MSP and =
OpenSoundWorld, which means they can communicate fairly easily with one =
another. =20

Re: [Osw-users] osw problems continue

[Amar <am...@pt...>]

I don't have an m-audio delta, so I can't reproduce your experience there
(anyone else out there have one?).
The way OSW utilizes CPU under Windows when audio is on is to take as much
CPU as the operating system will allow (thus it looks like 100% if you open
the CPU meter).  However, other applications will be able to run and grab
their share of CPU, and OSW's share will diminish accordingly.

Can you characterize "extremely slow", i.e., user-interface performance,
patch load time, DSP performance, etc?

Thanks.

[Osw-users] osw problems continue

[Oliver T. <th...@un...>]

i tried running osw on another windows 2000 machine (450mhz) with a 
different sound card (m-audio delta 1010). it was extremly slow and took 
all of the cpu it could get. i couldn't get any audio output from osw.

does anyone have success with multi-channel sound cards and osw on windows?

OSW works with 8.3 or 8.4 on Linux, Irix and OS X.
The Windows version is linked with Tcl82.dll (no symbolic link support), so
probably won't work with newer versions.

this is good to know, i had the impression osw is just not ready for 
serious work, but it seems to have problems only with my setup.

i experience the high latency with every patch. i have a windows 2000 
machine (latest service pack) with an rme digi96/8 soundcard (more pro 
than consumer). i guess it has something to do with the directsound 
drivers as the asio drivers work much better with other software, 
although other apps don't crash with directsound.

i cannot reproduce the crashes in osw, it just crashes sometimes.

as soon as i found a tcl rpm with threading enabled or manage it to 
compile a rpm by myself i will test it. but windows is my primary platform.

p.s.: does osw also work with newer tcl version (8.3 or 8.4)?

[Osw-users] linux: tcl errors on startup

[smoerk <sm...@gm...>]

hello,

i tried to run osw on linux, but i get errors on startup:

Error in startup script: can't read "::TransformPackage(Button)": no 
such element in array
     while executing
"return $::TransformPackage($transformClass)"
     (procedure "oswGetPackage" line 3)


could this error caused by an non-multithreading tcl installation?

do you know where i can get an rpm for redhat9 with multithreading enabled?

i will ask in the planet ccrma list, too.

thx,

Re: [Osw-users] first impressions

[Amar <am...@pt...>]

The answer is mileage varies depending on hardware, OS version, system
configuration, etc.  For my own work (which includes live performance), the
windows version has been extremely stable of late, running for multiple
hours w/o a crash.  Latency under windows depends on the audio device and
driver you are using - my general sense has been I can get around 20-30ms
gesture-to-output latency with unsophisticated DirectSound drivers using
Win2K or WinXP (I don't recommend an earlier version of Windows).

Could you provide me your OS, CPU and soundcard info, as well as an example
patch that crashes or causes the high latency?  This would be extremely
helpful.

The Linux version has more promise in my opinion for consistent low-latency
performance.  I get lower latency w/ Linux + ALSA, but occasionally the OSW
linux interface flakes out - others have had different experiences and may
wish to comment further.

Thanks.

[Osw-users] first impressions

[smoerk <sm...@gm...>]

hello,

i played around a little bit yesterday and today with osw and it's quite 
  impressive. i find it much easier to understand than pd and the 
"language" seems more high-level.

the problem is that it's mostly unusable for real work on my windows 
machine:

- big latency around 1 to 2 seconds.
- crashes very often
- dropouts when there are events in the gui

are these windows related problems? is the linux version more usable?


minor problems:

- ugly interface
- patches loading very slow
- no asio interface


osw would be a really nice program, if the stability and performance 
problems could be solved.

Re: [Osw-users] is the list active?

[Amar <am...@pt...>]

Yep, this list still exists - just not very much traffic (many people still
ask support questions 1-on-1).
Can you double-click on the file oswinit.tcl in your "Open Sound World"
directory and let me know what message appears?

Thanks.

[Amar <am...@pt...>]

Hi Mathieu-

   I have been compiling with g++ 3.2 on Linux and Mac OS X.  Yours is the
first experience I've heard with 3.3.  I have some ideas of what the problem
might be, however, and will look into it.  Meanwhile, feedback from anyone
else using 3.3 would be most helpful.

2)  New documentation for OpenSound Control, including basic features, =
remote-interface commands and revised help and tutorial patches.
3)  New transforms, including:
        LinesEditor - breakpoint function editor
        Slammer - non-real-time clock source for off-line processing
        ResPing - excitation of individual filters in a resonance model
        LoadPatch - Dynamically load/unload patches in response to =
events
        Drunk - ever popular drunk-walk sequence

[Osw-users] OSW and MacOs X

[<jof...@ya...>]

Hi,
I'm a mac os x user, I had no problem to install osw
but I can't open exemples patch.
At initialisation I have this message: 

kCGErrorFailure : GetGlyphAddresses failed: status = 5

and when try to load a patch (additive.osw):

Error: Could not find transform class Array

and then:

Unable to display patch due to "invoked "break"
outside of a loop"

Any Idea?

Mac Os 10.2.5
tcl 8.4.2

Re: [Osw-users] Re: Trying OSW

[Amar <am...@pt...>]

Hi John,

   Yes, as Wil mentioned, I'm currently maintaining the Windows version of
OSW (as well as the Mac version and the SGI version). I haven't run Windows
98 in a while, I've mostly been using XP for development and then testing on
2000.   One of the things that often gets tweaked in OSW is the
threading/scheduling system to acheive better realtime performance, and
threading is one of the things that works differently in 9x systems versus
2k/XP systems.  I will what I can do about getting hold of a 98 system on
which to test, but I would strongly recommend upgrading of real-time Csound
produces similar results.

   The ShepardTone patches are fairly compute-intensive, I think, but the
19-tone uses only a fairly quick-and-dirty square wave generator.  I tested
the "octave keys" and they sounded right, I will perform a more solid ET
test comparing listening results with a 19-tone tuning table on a Proteus.

  I don't know much about your particular sound card, and you said that you
had not yet tried out your USB midi interface, so we can probably rule that
out in this case.  I have had experiences with USB midi devices don't always
play nice with some sound devices (e.g., Creative Extigy).

  Wil is right in saying that OSW is designed to run in real time from the
ground up, but you can stream to and from disk using the SampleStreamer,
SampleWriter and whatever processing you want in between.  It will not run
"faster than real time" until I finish development of the non-realtime clock
source, but that may not be a major issue in this case.  I'd be interested
to learn what sort of experience you have if you try using OSW this way.

   Regards,
    -Amar

If the OSW demo you're talking about is the can_you_say.osw patch, I don't
think it is supposed to make sound- yet. How is the sound quality poor?
Does the audio start "crackling"? Have you tried any of the simpler audio
patches in the tutorial/audio folder?

You're using the windows binary? I have no information on OSW running
under windows 98- that might be an issue. I'll cc this message to the OSW
users' list- maybe Amar can shed some light on this. He is the
creator/initial developer of OSW, as well as the Windows maintainer.

Cool. It sounds like you have a history of early adoption.

OSW was designed from the ground up as a realtime language. As far as I
know, there is no way to run it in non-realtime. But, then again, realtime
is so much more fun. : )
