The first unified LV2 release, LV2 1.0.0, is out.
This release merges the previous lv2core package with all the official
extension packages, as well as example plugins, lv2specgen, and
additional data. From a developer point of view, the biggest change is
that all LV2 API headers can be used by simply checking for the single
pkg-config package "lv2" (for compatibility the previous "lv2core"
package is still installed). Implementations are encouraged to abandon
the "copy paste headers" practice and depend on this package instead.
With this release, several new extensions have become stable that
together greatly increase the power of LV2: atom, log, parameters,
patch, port-groups, port-props, resize-port, state, time, worker.

QMidiArp 0.5.2 has just seen the light of the day. It brings mainly
two improvements. One is a comeback, that of tempo changes on the fly,
and that now includes also tempo changes of a potential Jack Transport
master. Also the Jack Transport starting position is finally taken into
account, so that QMidiArp should be in sync also when starting the
transport master not at zero.
The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen!
Note that for compiling in NSM support you will now need liblo as dependency.
Enjoy, and enjoy LAC in Graz this year
QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO.
Everything is on
o Tempo changes are again possible while running, both manually or by
a Jack Transport Master
o Jack Transport position is now taken into account when starting,
QMidiArp used to start always at zero
o Muting and sequencer parameter changes can be deferred to pattern
end using a new toolbutton
o Modules in the Global Storage window have mute/defer buttons
o Global Storage location switches can be set to affect only the pattern
o Non Session Manager support with "switch" capability (thanks to
Roy Vegard Ovesen)
o NSM support requires liblo development headers (liblo-dev package)
QMidiArp 0.5.3 fixes a number of bugs and should from now on replace 0.5.2. It also has some minor functional improvements, all is listed below.
With thanks to all reporters, contributors and translators.
QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO for Linux with ALSA and JACK MIDI backends.
Downloads are available at
o Random functions for sequencer and LFO steps and arp repeat mode
(feature request #5 Keith Milner)
o NSM support now handles import/export/clear to facilitate
getting started (Roy Vegard Ovesen)

o Sequencer transpose slider is now MIDI controllable (MIDI-learn)
(feature request #7)
o Sequencer pattern maximum length extended to 32 bars
(feature request #6)
o LFO offset jumped back to fixed value when MIDI controlled
(bug #6 distrozapper)
o Arp trigger behavior was not practical with chords pressed on keyboard
(bug #7 Burkhard Ritter)
o JACK Transport no longer worked when no JT Master tempo was present
(bug #5 Barney Holmes)
o Deleting an arp pattern in text window while running caused crash
o Note lengths were not consistent between alsa and jack backends
o Note lengths did not account for current tempo
o Sequencer did not honor "D" button when MIDI controlled
o Seq note length is now a 16th at half slider scale
8th interview here, this week with Julien Claassen. Julien's a long time
member of the community who most of us know well.
Thanks to Julien for a great interview!
The interview series will take a 2 week break with this post, and will be
back again on the 13th of December. Cheers!
On behalf of the entire Rivendell development team, I'm pleased to announce the availability of Rivendell v2.5.5. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License.
From the NEWS file:
*** snip snip ***
If upgrading from a v1.x version of Rivendell, be sure to read the
'UPGRADING' file before proceeding for important information.
RLM API Extension. Added new fields to the 'rlm_pad' struct to
allow plug-ins to determine actual and predicted start times for events.
RDMonitor Enhancements. Extended RDMonitor to allow proper positioning
on multi-head displays.
LiveWire Switcher Driver Changes. The switcher drivers for LiveWire
have been refactored into three separate drivers:
LWRP Audio - Allows switching of audio routes on LiveWire devices.
LWRP GPIO - Allows monitoring and control of LiveWire GPIO devices
via LWRP (both virtual and direct).
Multicast GPIO - Allows monitoring and control of LiveWire console
GPIO without the need for a virtual LWRP device.
See 'SWITCHERS.txt' for details.
RDSelect Enhancements. Added support for specifying CAE and RDXport
service assignments via RDSelect configurations.
Multiple bug fixes. See the ChangeLog for details.
This version of Rivendell uses database schema version 220, 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.

The New Interfaces for Musical Expression (NIME) conference comes to London
We would love to receive contributions from LAU community, and given the
LAC conference is around the same time, this make the chance for a great
summer of weird sounds!
Please see below the call for proposal and circulate as appropriate.
The Performance and Installation call for NIME 2014 is out now and the
deadline for submissions is in LESS THAN TWO WEEKS' TIME: 1st
December, with no late submissions accepted. We would therefore like
to encourage everyone to get thinking about what they might like to
present in this category!
For NIME 2014, we will be hosting performances and gigs in a variety
of venues around Central London. We plan to make some of these events
open to the public and are looking for really high quality
performances, from proven performers and makers.
We hope to include a diverse range of performances, and so are keen to
receive proposals which are out of the ordinary. For example, work
which focusses on the body in performance, such as the human voice,
the body in dance, or indeed music which makes audiences dance. We
also encourage works which challenge the conventions of NIME, such as
notions of liveness, or the role of notation, language or code in
performance. Historical perspectives on music performance technology
are also welcomed, for example work which combines computation with
textiles, augments traditional instruments, or draws on
complementarity with visual forms. With the increasing influence of
the maker movement, we also welcome proposals which include ad-hoc,
DIY and open source instruments.
If you have something you'd like to show in a less polished way, you
can simply tell us you'd like to show a 'performance demo' and these
will be most likely programmed in smaller venues closer to the
The call can be viewed at the link below.
If you have any questions, please contact the artistic committee here:
Hope to see some of you there!

I wanna share with community my very simple Jack session manager. It console app and is intended to use from scripts ( even if this is rc.local ;-) - or it could be linked to some icon/activator on desktop ;-)
It use libconfig for store settings and CDK ( ncurses ) for display while it "watching".
In save mode it works almost like jack_session_notify ( this part of code was partially borrowed, but was fixed, optimized and adapted - e.g. it doesn't store duplicate connections. take care of trailing slash in session directory, use libconfig etc. ).
Load mode was written from scratch. It start stored apps, restore it's connections and then it works like watchdog. It should be ( and it is at least for me ;-) useful for live performances.
There is also simple script which merge this two functionality, and it can also start start jack and wineserver (in persistent mode), export WINE_RT variables etc.
Check this url:
I use this already in my band, so let this publicity of our song will be my "salary" ;-)

We are happy to announce the next issue of the Linux Audio Conference
(LAC), May 1-4, 2014 @ ZKM | Institute for Music and Acoustics, in
The Linux Audio Conference is an international conference that brings
together musicians, sound artists, software developers and researchers,
working with Linux as an open, stable, professional platform for audio
and media research and music production. LAC includes paper sessions,
workshops, and a diverse program of electronic music.
*Call for Papers, Workshops, Music and Installations*
We invite submissions of papers addressing all areas of audio processing
and media creation based on Linux. Papers can focus on technical,
artistic and scientific issues and should target developers or users. In
our call for music, we are looking for works that have been produced or
composed entirely/mostly using Linux.
The online submission of papers, workshops, music and installations is
now open at http://lac.linuxaudio.org/2014/participation
The Deadline for all submissions is January 27th, 2014 (23:59 HAST).
You are invited to register for participation on our conference website.
There you will find up-to-date instructions, as well as important
information about dates, travel, lodging, and so on.
This year's conference is hosted by the ZKM | Institute for Music und
Acoustics (IMA). The IMA is a forum for international discourse and
exchange and combines artistic work with research and development in the
context of electroacoustic music. By holding concerts, symposia and
festivals on a regular basis it brings together composers, musicians,
musicologists, music software developers and listeners interested in
contemporary music. Artists in Residence and software developers work on
their productions in studios at the institute. With digital sound
synthesis, algorithmic composition, live-electronics up to radio plays,
interactive sound installations and audiovisual productions their
creations cover a broad range of what digital technology can inspire the
musical fantasy to.
The ZKM is proud to be the place of the LAC for the fifth time after
having initiated the conference in 2003.
We look forward to seeing you in Karlsruhe in May!
