Jackbeat is an audio sequencer running on Linux and Mac OS X, for musicians
and sound artists:
* Drummachine interface with animations for easy and playful editing
* Built for both composition and live setups with high interactivity needs
* Extremely easy to use but yet powerful by connecting with other
applications and plugins using JACK and OSC
* Loads and saves .jab files, Jackbeat's xml+tar open file format
* Supports native audio devices, PulseAudio and JACK
* The GUI has been re-designed for the pleasure of the eye and more ergonomy
* New shortcuts, knobs and waveform animation bring more interactivity
* OSC is now supported with a fair amount of methods and events
* Mac OS X integration has been much improved
* ALSA, CoreAudio and PulseAudio are now directly supported in addition to JACK
* Several bugs and usability issues have been fixed
* The internal architecture has been improved
Package maintainers will certainly want to have look at the ChangeLog to learn
about the new dependencies:
The Web site for the PHASEX softsynth has been rehabilitated and is now
Packages are available in tarball and RPM (Fedora 6) formats.
Please note that this is not an update. I've merely put the site back
Ubuntu Studio is a multimedia editing/creation flavor of Ubuntu, built
for the GNU/Linux audio, video, and graphics enthusiast or
The Ubuntu Studio team is proud to announce its fifth release: Ubuntu
Studio 9.04. With this release, which you can download in a 1.2GB DVD,
Ubuntu Studio offers a pre-made selection of packages, targeted at
audio, video and graphics users. Ubuntu Studio greatly simplifies the
creation of Linux-based multimedia workstations.
For Ubuntu Studio 9.04 we have continued to update packages and fix
critical bugs to better the Ubuntu Studio user experience.
We are happy to announce the real time kernel will be installed by
default in Ubuntu Studio in this release, if the audio task is
selected. We have tested it heavily and are happy with it's
performance in audio environments.
The art has had a cool facelift. The gtk theme has been improved
staying in the 'Studio' style. Plus the gdm theme has been switched to
some great new eyecandy.
New applications included:
* FFADO firewire soundcard drivers
* Calf audio plugins
* LMMS (updated and included in the meta packages)
* Heavily tested 2.6.28 realtime kernel for low-latency audio work
* Jack Connection Kit upgraded to 0.116.1 (a major improvement)
* Ardour upgraded to 2.7.1
* Fresh ubuntustudio-looks improvements
* Addition to Ubuntu Studio Controls to allow users to maintain
o Ctr+Alt+Backspace behavior
See the Ubuntu release notes for other non Ubuntu Studio specific changes.
See http://calf.sourceforge.net/ for more information about CALF.
As our wiki page at https://wiki.ubuntu.com/UbuntuStudio states, "our
aim is to make it more accessible for new users to get into the tools
that GNU/Linux has to offer for multimedia creation and production. We
also want to spotlight what's out there, and show users tools they
might not know to exist."
Thanks to all who helped in Ubuntu Studio 9.04's creation!
the videos from lac 2009 are being made available at
most of the footage is there - the missing stuff will follow in a few
days as florian (aka faberman) gets home from a production in italy and
finds time to encode the rest.
the video quality this year is quite stunning - thanks to the theora
team for huge improvements in efficiency and quality. if you are a video
person and haven't upgraded to the thusnelda branch encoder, do it NOW
(before even going for a coffee). then hit #theora on freenode.net and
sign hymns of praise until they kick you out.
you will note that the videos are raw - they could use trimming some
talks consist of several fragments that need concatenating, but due to
some stream problems they caused oggCat to barf, even though every
single fragment plays ok. your help is appreciated - get in touch with
me off-list or via l-a-d if you have worked on the stuff and would like
to upload your improved version.
On behalf of the entire Rivendell development team, I'm pleased to announce
the release of Rivendell v1.4.0. Rivendell is a full-featured radio
automation system targeted for use in professional broadcast environments. It
is available under the GNU General Public License. Changes in this release
include (from the NEWS file):
*** snip snip ***
Unique Cart Titles. It is now possible to configure the system (in
RDAdmin->SystemSettings) to disallow duplicate cart titles.
RDAirPlay Full Log Controls. New controls have been added to the Full Log
widget in RDAirPlay to allow the head and tail of carts to be auditioned, as
well as a set of log runtime counters. To make these controls visible, it
is necessary to check the 'Show Extra Buttons/Counters' box in
RDCastManager Enhancements. An Podcast episode filter has been added. Also
added to the online version is the ability to audition each episode by
downloading the media file to the local system.
Bugfixes. See the ChangeLog for details.
This version of Rivendell uses database schema version 177, and will
automatically upgrade any earlier versions. To see the current schema
version prior to upgrade, see RDAdmin->SystemInfo.
As always, be sure to run RDAdmin immediately after upgrading to allow
any necessary changes to the database schema to be applied.

Dear Linux Audio Developers,
as indicated by Stéphane in his presentation  he gave at LAC2009 today, I
finally handed in my diploma thesis, which I announced here . You can
download the full text of the thesis here:
If you want to take a glimpse at the code, you can get a (still very dirty)
snapshot of the code here .
The abstract of the thesis:
> Several available free software audio solutions were analyzed, and
> Jackdmp—a C++ reimplementation of the renowned JACK Audio Connection
> Kit—was selected as the most appropriate solution for a real-time audio
> architecture on DROPS. The JACK sound architecture provides the lowest
> processing latency possible on a desktop computer for a given set of sound
> card parameters. It reduces the latency jitter caused by software to zero
> and synchronizes streams at sample accuracy.
> A real-time admission scheme for JACK clients is proposed.
> The execution time of different typical JACK clients was analyzed with
> measurements to validate the assumptions the proposal is based on,
> but also to gain further knowledge about their timing behavior.
> The measurements showed that the condition set by Paul Davis—the
> time to process a client must be a linear function of the buffer size—holds
> for all tested clients.
> Jackdmp was ported to DROPS. The developed design of the port and its
> implementation is documented here. Measurements showed that—although
> the real-time performance of the Linux kernel is continously being improved
> in the mainline and on special external branches—DROPS can provide a
> signaling latency that is two times lower on average than the values that
> can be achieved on the same machine running with a low latency patched
> Linux kernel. Thus, it can be stated that DROPS is well-suited for
> real-time audio processing and that the pursued path to use it as the
> foundation of a truly real-time capable audio workstation should be
As of the project's future: I will try to get the ALSA driver and the
connection with L4Linux working until the presentation of the project (no
date set so far, but probably in 2--4 weeks or so). If all works well, we
will consider releasing a demo disc and / or a Youtube demonstration for
interested developers and power users of the system then. And then we'll
Kind regards --- and those of you who are in Parma: Have an interesting
conference and a great time in Italy! ---,

location here as soon as the document is published there.

The reports of the jMax death have been greatly exaggerated. Free
software never dies, it just sleeps for some time. Almost nine years
after the release of the project under a free license, and six years
after the end of the developments by the institution that created it,
some of the original project developers decided to revive it from its
ashes: jMax Phoenix was born.
JMax is a community project, not controlled by a single institution; it
was Started from some of the original jMax developers in the summer of
2008. The project priorities are to give jMax a modern User interface,
to integrate it into the modern Linux audio environment, and, last but
not least, scalability. Detailed plans for the projects are presented in
these days at the Linux audio conference 2009 in Parma. Check the
proceedings for more information.
We are looking for, core developers (C, Objective C, Java, Swing),
object developers (DSP, Control), porevelopers to port existing
libraries, testers and early users, and a graphic designer. Please not
that the jMax Phoenix project is a fork of the original code base and
cvs. For those who know the jMax history, jMax Phoenix started from jMax
2.4.5. Later developments will be backported if judged interesting.
The developments are today focused on the user interface: more than one
third of the code has been rewritten, and the rest heavily modified to
provide an interface aligned with modern standards.
The project home page is http://www.jmax-phoenix.org, where you can find
the main page and a wiki including user documentation and design
documents. The project team can be contacted at contact(a)jmax-phoenix.org.
The project sources and mailing lists are hosted by sourceforge, at
http://sourceforge.net/projects/jmax-phoenix/; please, join the
developers mailing list to follows the project evolutions, give your
opinions or express your needs.
You’ll find snapshot binary releases on the sourceforge site; they are
versioned using the subversion revision number; these snapshots are not
yet supposed to be stable or fully functional, but they currently give a
pretty good idea of the evolution of the user interface. The user
documentation in the wiki will be kept consistent with the last snapshot
JMax Phoenix is release under the original jMax license, GPL with an
exception for loaded package, and the is copyrighted either by Maurizio
De Cecco, François Dechelle and Enzo Maggi, or by Ircam, or by both set
Hoping to see you on the jMax mailing list.

On behalf of the FluidSynth team I'm very happy to announce the release
of version 1.0.9 - "A Sound Future".
The nickname for this release was chosen based on the recent development
interest in the project and the addition of new team members. This last
development cycle is the result of contributions from many individuals.
The future of FluidSynth is looking bright and we are working to create
a more regular release schedule and plan for innovation and improvement.
