Hallo,
this message is to inform the community that in the next edition of the
the "Salon Linux 2010", in march 2010 in Paris, a french Linux event
including a conference cycle, there will be a session around
professional music and video creation with free software.
You can find the call for contribution at
http://www.confsolutionslinuxparis.com/.
The call talk about contribution and not paper because actually
only a presentation is required, not a paper.
We are looking mostly for overviews of availables solutions or
in depth presentations of mainstream ''products''.
Unfortunately, the communication must be in french :-< ...
Feel free to distribute this mail where do you think it may be
appropriate, or to contact me to get more details.

Hi Rui :)
after it failed to send the wanted test to you, because of it's length,
I'm blocked :D.
Sorry LAD list, Rui is waiting for this test and I don't know how to
reach him, while I'm blocked.
Cheers,
Ralf

Hi Rui :)
first I got some noise references.
spinymouse-sudo@64studio:/usr/src/qtractor/noise$ wget
http://upload.wikimedia.org/wikipedia/commons/6/66/Whitenoisesound.ogghttp://upload.wikimedia.org/wikipedia/commons/6/6c/Pink_noise.ogghttp://upload.wikimedia.org/wikipedia/commons/c/c9/Brownnoise.ogg
Then I set the CPU frequency scaling to "Performance" and launched JACK
and after JACK I run Qtractor.
spinymouse-sudo@64studio:/usr/src/qtractor/noise$ jackd -Rdalsa -dhw:0
-r96000 -p512 -n2 -Xseq
spinymouse-sudo@64studio:/usr/src/qtractor$ qtractor -v
Qt: 4.4.0
Qtractor: 0.4.3.1409
spinymouse-sudo@64studio:/usr/src/qtractor$ qtractor
I Imported the three noise.oggs.
Qtractor didn't show the waveform for the brown noise recording
completely, I don't know the reason why and I never had this bug or user
error before, but it's also the first time I used 0.4.3.1409. I tried to
record it 2 times.
I did stereo recordings for the mono clips too, because this shouldn't
cause any changes for the audible result.
Okay, a completely new problem occurred. There's an audible loss for the
quality of the sound, but in this case because of an understandable
reason. The .ogg files are to loud with faders set to +- 0 db. The
important thing with this is, that the loss of the sound quality for the
white noise is comparable with the kind of loss I've got when doing a
recording of music, even if the maximal signal level is under -3 dBFS.
So it doesn't matter if the meters are Full-Scale Square wave or
Full-Scale Sine Wave meters. Anyway, I wonder where the boost is from.
When I recorded music by connecting Qtractors outputs to its inputs
both, source clip and target clip were 96-24-stereo.wav files. There
never was a visible difference for the volume.
Before I go on comparing music recorded by Qtractor and Audacity, I want
some information because of the strange level for the .ogg files from wiki.
The qtractor session is attached as tar.gz. I suppose you'll have a
directory /usr/src/qtractor too, thus you just need to add a directory
/usr/src/qtractor/noise.

Hi, I have been developing a fork of the Aldrin tracker. If anyone is
interested you can take a look at it at
http://sites.google.com/site/neilsequencer/ It's main aim is to keep a
stable and usable project with a good plugin set.

I've been playing with Non-sequencer over the last few days, love the simplicity and uncluttered approach to the programme, however I'm finding if run alongside Hydrogen or Ardour, the tempo drifts out of sync, this occurs playing any song longer than a couple of patterns. The obvious answer to this is to have ardour as jack transport master, Non-sequencer does not like this however and crashes. I post the question here rather than Linux Audio Users because I plan to write applications utilising Jack MIDI myself and am wondering the best approach to implement tempo in absence of alsa sequencer, which I found quite nice to use but still jittery even with high res timers / real time kernels.
... seems to have been announced. I got an email from ICMA about it.
Why was it not announced here or in the Consortium list? I would
have thought these are the main places where you find good interest.
Any further news?
Victor
hi everyone!
is the rme hdspe raydat supported under linux?
if so, any raydat users here with success or horror stories?
if not, is there an alternative that has at least 3 adat i/o,
preferrably 4 and uses pci express?
i know of (and like) the rme 9652 cards, but i'd rather not buy pci
cards anymore.
thanks in advance,
jörn
Hello all,
A number of system here, including the ones at the Casa
del Suono are to be upgraded in the coming weeks.
At the moment they all run Fedora 8, so the first choice
would be to go for Fedora 11. But:
* None of them will run Gnome or KDE.
* Most will be headless anyaway.
* I want access/privilege control to be based on
user and group ID and nothing else. Privileges
will never depend on the user having a local
login or desktop session.
* I'm prepared to have to spend some time configuring
udev, pam, /etc/fstab etc. etc. etc.
* What I certainly *do not want* is some parallel
access control system that would interfere with
the above, or that could modify/bypass/enhance
in any way what has been configured there.
* I'm *not* really prepared to have to waste any time
reconfiguring the Kit family. Consequently I don't
want to see any of them.
So what distro should I go for ? Having to spend weeks
compiling everything from source is not an option.
Anyone able to point in the right direction will receive
my eternal gratitude which could be expressed in quantities
of fine Italian food and drinks if the occasion arises.
Ciao,

Io lo dico sempre: l'Italia è troppo stretta e lunga.
Here's a story that may give you all a good chuckle:
Last weekend Robin Gareus, our LAO guru has contacted me inquiring why there
was a ~1hr linuxaudio.org server downtime that took place that Sat. morning.
Luckily we now have an UPS that gives us almost 2 hours of offline power.
Hence, the server went through this unscathed. Yet, the network
infrastructure was also down so even though the server remained up, there
was no way of reaching it.
So, I went investigating what happened, and this is the reply I got from our
on-campus support:
Squirrel fried in transformer. Campus and part of downtown was out of power
on Saturday morning before the game. [this was a football game we had in
town that day with 10K+ visitors]

In the new jack API the function jack_client_new ist deprecated.
Actually it's not only deprecated:
Apps using it don't play any sound,
as I've experienced with alsaplayer, and fluidsynth for example.
I'm thus inviting
1. to change all apps which still use jack_client_new to use this instead:
//jack_client_t*
jclient = jack_client_open( name, //jack_options_t
JackNullOption, //jack_status_t * status
NULL
);
2. to make the new jackd work with jack_client_new for some time
still, until most apps have adjusted their code
Thanks for the advertence.
