KMid2 is a MIDI/Karaoke player for KDE4.
KMid was developed more than ten years ago, so it was time for a revamping.
KMid2 is a rewrite from scratch, with a new architecture and also some new
This is a preview release. Should not be used in production.
Here are some major features:
* Plays MIDI and Karaoke files.
* Playback to external hardware MIDI devices.
* Allows to use software synths as well.
* Tempo and volume controls.
* Pitch (transpose) control.
* Rhythm view (visual metronome).
* Configurable character encoding, font and color for lyrics.
* Playlists (song collections).
* MIDI Mapper.
* Channels window, with solo/muting controls and instrument selectors.
* Piano player window, using VMPK artwork and technology.
* Runs in Linux, using the ALSA Sequencer.

I'm happy to announce a new guitarix release
guitarix is a simple Linux Rock Guitar amplifier and is designed
to achieve nice thrash/metal/rock/blues guitar sounds.
Guitarix uses the Jack Audio Connection Kit as its audio backend
and brings in one input and two output ports to the jack graph.
Release 0.05.2-1 comes with some changes:
* remove dependency of the boost library
(Many thanks to "thrasher13b" for the patch)
* fix missing "./" in ./debian/rules reported
by GMag (AV Linux)
* add 2 Channel gain and delay chooser to the
Jconv settings widget.
* add scroll/zoom mode to the wave view
* reworked Jconv settings widget UI
* various GUI and feature clean-up's
The standalone version of guitarix is based on GTK2+.
But guitarix is also released as a suite of LADSPA plugins
and can be used in e.g. ardour.
guitarix is licensed under the GPL.
Project page with screenshots:
For capture, guitarix uses the external application
'jack_capture' (version >= 0.9.30) written by Kjetil
S. Matheussen. If you don't have it installed,
you can look here:
For extra Impulse Responses, guitarix uses the
convolution application 'jconv' created by Fons Adriaensen.
If you don't have it installed, you can look here:

Dear fellow Linux enthusiasts and consortium members,
Please allow me to bring to your attention the upcoming L2Ork debut:
On December 4th Virginia Tech DISIS (<http://disis.music.vt.edu>) Linux
Laptop Orchestra (L2Ork, <http://l2ork.music.vt.edu>) will hold its first
sneak preview debut performance on Virginia Tech (VT) campus, Squires Studio
Theatre, starting at 7pm. Admission is free.
At noon on the same day, L2Orkists will also host a demo booth outside the
Commonwealth Ballroom in Squires Student Center (VT campus) demoing how

as has been announced here 2 days ago by Marc Groenewegen, the next Linux
Audio Conference (LAC#8) will take place at the HKM in Utrecht, Netherlands,
from May 1st - 4th, 2010 (see http://lac.linuxaudio.org/2010).
We have now opened the Website that accepts paper submissions. Please direct your
browser to http://lac.linuxaudio.org/2010/openconf
For those who have been following the LAC activities in the past years: It's
the same used&tested "OpenConf" web-based system that allows us to easily collect
paper submissions, review them and create a programme from accepted papers.
The available categories for paper submission looks like this:
* Live performance
* Audio Hardware Support
* Signal Processing
* Music Composition
* Audio Languages
* Sound Synthesis
* Audio Plugins
* Music Production
* Linux Kernel
* Physical Computing
* Interface Design
* Linux Distributions
* Networked Audio
* Media Art
Note that "Video" is also in the list. Yes, that's not strictly Audio :-), but
we feel that the two disciplines are close enough to one another to allow
opening up the conference scope a bit here. After all, we have already had
several very nice audio/video gigs in the past (some might remember the YUE
concert in Karlsruhe 2006 with a remote VJ live from Italy, which was pretty
groundbreaking at that time).
Also, we very much welcome practical papers resp. software demos ("how I use
Linux Audio applications to create my music/media art").
The web page also holds the paper templates that have to be used for submissions.
Pick one of the two provided templates (LaTeX or OpenOffice), author your paper
and convert it to PDF, then upload that PDF. Make sure you are using A4 as
- The conference is held in English, so the paper has to be in English too.
- Length of a paper is 4-8 pages. Papers have to include an abstract (50-100
words). Also, papers should include up to 5 keywords.
- The copyright of the paper remains with you (of course), but we reserve the
right to create printed proceedings from all submitted (and accepted) papers.
- We have fixed the following dates:
- Deadline for paper submissions: February 14th, 2010
- Notification of paper acceptance: March 14th, 2010
- Deadline for final version of paper: April 4th, 2010
Please note that the OpenConf system is only to be used for paper submissions;
for concert pieces ("Call for Music") or sound installation proposals, please
contact us directly by email ("lac -at- linuxaudio -dot- org ").
We are looking forward to many interesting submissions for the 8th
Linux Audio Conference and we hope to see you in Utrecht in 2010!
Please feel free to forward this e-mail to anybody who might be
interested - mailing lists, blogs, Linux portals, magazines, you name them.
Public relation work for this conference is something we need, and where
everybody can easily help.
Thanks for reading.
On behalf of the LAC2010 organisation team,
Jackbeat, the minimal-but-nevertheless-useful multi-platform step sequencer, has
just reached version 0.7.3 !
This is mainly a bugfix release, that you can grab from:
It's easy to build and easy to try.
- Tracks can now be reordered
- A buffer overflow and a bug preventing to load some jab files have been fixed
* #40: allow to reorder tracks (move up/down)
* #43: fix buffer overflow in core messaging routine
* fix bogus track name conflict when loading jab, thanks Florent
Tarball containing D-Bus patched jack 0.118.0 is available here:
D-Bus modifications add optional autodetected support for the D-Bus
based server control system.
D-Bus is object model that provides IPC mechanism. D-Bus supports
autoactivation of objects, thus making it simple and reliable to code a
"single instance" application or daemon, and to launch applications and
daemons on demand when their services are needed.
* Simplified single thread model for control and monitor
applications. Various D-Bus language bindings make it trivial to
write control and monitor applications using scripting languages like
Python, Ruby, Perl, etc..
* JACK has log file (~/.log/jack/jackdbus.log) that is available for
inspection even when autoactivation happens because of first JACK
application is launched.
* There is real configuration file used to persist settings that can be
manipulated through configuration interface of JACK D-Bus object.
* Improved graph inspection and control mechanism. JACK graph is
versioned. Connections, ports and clients have unique (monotonically
increasing) numeric IDs.
* High level abstraction of JACK settings. Allows applications that can
configure JACK to expose parameters that were not known at compile
(or tarball release) time.
Currently there are some minor differences between jack1 jackdbus and
* There is no parameter constraints support (no enums and no ranges)
* No get client pid function (probably affects lash)
* Settings file (in ~/.config/jack/) is conf-jack1.xml instead of
conf.xml, because jack1 and jack2 settings and not really compatible.
When configured with D-Bus support, jack_control is
installed. jack_control is simple commandline interface for jackdbus.
Other tools that can communicate with JACK through D-Bus:
* LADItools (tray icon, configuration, etc.)
* Patchage (and lpatchage too)
* LASH 0.6.x
