A first edition of the LAC2009 website is now
on line at
Apart from the initial announcement you'll
find there the calls for papers and music,
and some related documents.
More information will be added in the coming
The site is (surprise !) hosted by linuxaudio.org,
site administrator is Robin Gareus, with design
and layout by Christoph Haag.
For the paper submission and review we are again
using openconf, with Frank Neumann at the controls.

Lascia la spina, cogli la rosa.
I'm glad to announce the new 0.1.1 relase of NASPRO.
NASPRO, recursive acronym for "NASPRO Architecture for Sound
PROcessing", is a free/open source, modular and cross-platform sound
processing framework with a strong emphasys on interoperability.
Its main aim is to provide users and developers a full-featured tool
to do sound manipulation using heterogeneous technologies which are
already available (such as LADSPA or LV2 plugins) and at the same time
make it easy to develop new ones without breaking interoperability.
Please, keep in mind that it is work in progress and that we're in
early stages of development.
New stuff in this release:
* new build system (which sucks, but it's better than before);
* NDF 0.1 file format support;
* CPU endianess neutrality;
La Casa della Musica invites all Linux Audio developers,
users, composers, musicians, philosophers and anyone
The Linux Audio Conference 2009
16-19 April 2009
La Casa della Musica
The LAC will go outside Germany for the first time, but
we will keep close to the familiar four-day format with
paper presentations, workshops, electro-acoustic music
concerts, and the Linux Sound Night.
The website is being created, and 'calls for everything'
will be issued before the end of this week.
The conference starts a few weeks later than the previous
one, which allows the deadlines for everything to be moved
as well. For the papers and music calls this will be
somewhere mid January, so you can use the end-of-year
holiday period to get creative.
We hope to see you all in Parma !

On behalf of the entire Rivendell development team, I'm pleased to announce
the release of Rivendell v1.1.0. 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 ***
Custom Encoders. It's now possible to configure Rivendell on a
host-by-host basis to use any command-line audio encoder (e.g. FAAC,
FFmpeg) to drive exports, uploads and podcasts. Information on setting it
up can be found in 'ENCODERS.txt'.
GPIO Enhancements. The syntax of the 'GPI Set' [GI], 'GPO Set' [GO]
and 'GPI Enable' [GE] RMLs has been extended and the underlying system
modified to allow operation of all three commands with both GPI and GPO
devices. The old syntax is now deprecated, but still supported for
backwards compatability. Information on the new syntax can be found in
New Record RMLs. Two new RMLs, 'Start Record Deck' [RS] and 'Stop Record
Deck' [RR] have been added, allowing any RDCatch record deck to be
controlled via RML. Information on the new RMLs can be found in 'rml.sxw'.
RDLogEdit Runtime Counters. Time counters have been added in the Edit Log
screen in RDLogEdit that show the predicted running time of log events from
the currently selected event to the next STOP and the end of the log, while
highlighting multiple events will display the runtime of the selected
Metadata Import Enhancements. Support has been added for importing
metadata from files generated by the BE AudioVault system (chunk type
This version of Rivendell uses database schema version 162, 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.

This is a maintenance release, fixing a crash in Windows when playing certain
MIDI files and connecting a player output to VMPK input. The reset all button
now also resets the internal controllers states. The number of keys is now
constrained to reasonable limits within the MIDI notes range. The "grab
keyboard" feature is now an optional runtime setting, as a workaround for
some broken X11 window managers and desktops.
Thank you very much for the feedback!
Virtual MIDI Piano Keyboard is a MIDI event generator and receiver. It doesn't
produce any sound by itself, but can be used to drive a MIDI synthesizer
(either hardware or software, internal or external). You can use the
computer's keyboard to play MIDI notes, and also the mouse. You can use the
Virtual MIDI Piano Keyboard to display the played MIDI notes from another
instrument or MIDI file player.
* bug #2143187 Documentation
* bug #2158014 Crash in Windows
* bug #2142335 Keys played beyond the upper MIDI note limits
* bug #2142321 Reset all button

Qtractor 0.2.2 (flirty ditz) is out!
Qtractor is an audio/MIDI multi-track sequencer application, written in
C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its
main infrastructures and Linux as native and exclusive platform.
Specially suited to the lone-wolf composer, arranger and (re)creative
music-maker personal home-studio, it still hopes to evolve as a fairly
featured desktop audio/MIDI workstation or at least, a prototypal part
of it ;)
* Stephen Doonan joined documentation team and revised the user manual.
* Spurious MIDI events recording bug ow fixed.
* Audio track monitoring and plugin loop processing slightly improved if
* MIDI clip editor improved precision and correct snapping.
* Multiple track mute and solo one-click toggling (NEW).
* Better MIDI connection persistance across sessions.
* Record-armed tracks aren't muted on playback anymore (NEW).
* Optimized audio clip waveform caching and drawing.
* Many more or less fixes (see change-log)
- source tarball
- user manual
Weblog (upstream support):
Qtractor is free, open-source software, distributed under the terms of
the GNU General Public License (GPL) version 2 or later.
- Multi-track audio and MIDI sequencing and recording.
- Developed on pure Qt4 C++ application framework (no Qt3 nor KDE
- Uses JACK for audio and ALSA sequencer for MIDI as multimedia
- Traditional multi-track tape recorder control paradigm.
- Audio file formats support: OGG (via libvorbis), MP3 (via libmad,
playback only), WAV, FLAC, AIFF and many, many more (via linsndfile).
- Standard MIDI files support (format 0 and 1).
- Non-destructive, non-linear editing.
- Unlimited number of tracks per session/project.
- Unlimited number of overlapping clips per track.
- XML encoded session/project description files (SDI).
- Point-and-click, multi-select, drag-and-drop interaction (drag, move,
drop, cut, copy, paste, delete, split)
- Unlimited undo/redo.
- Built-in mixer and monitor controls.
- Built-in connection patchbay control and persistence (a-la QjackCtl).
- LADSPA, DSSI and native VSTi plug-ins support.
- Unlimited number of plug-ins per track or bus.
- Plug-in presets, programs and chunk/configurations support.
- Audio/MIDI clip fade-in/out (linear, quadratic, cubic).
- Audio clip time-stretching (WSOLA-like or via librubberband),
pitch-shifting (also via librubberband) and seamless sample-rate
conversion (via libsamplerate).
- Audio/MIDI track export (mix-down, merge).
- Audio/MIDI metronome bar/beat clicks.
- MIDI clip editor (piano roll).
- MIDI instrument definitions (a-la Cakewalk(tm))
- JACK transport sync master.
- MMC control surface enabled.
- Configurable keyboard shortcuts.
- Slight optimization in audio and MIDI meters refresh rate.
- Another ancient bug has been squashed: MIDI events were being recorded
even though recording wasn't rolling; spurious event times were being
recorded due to an absent started queue.
- Major fix applied to audio track monitor metering, and most
importantly to plugin processing, correcting tentatively all audio
buffer offsetting and slicing due on loop turnarounds.
- Fixed a potential crash and/or simple record dismissal when changing
properties of a track already armed for recording; prevent record
engaged tracks from editing or removal.
- Lighten up the connections line and highlight colors, as seen to fit
best on some darker background themes.
- Several icons refined with slight transparent shadowing.
- Send/reset all MIDI buses and track controllers (ie. volume and
panning) only when main transport playback is started, avoiding the
pouring on eg. loop, playhead or tempo changes.
- Pressing the Escape key also clears current selection in the main
track-view and MIDI clip editor; resizing multiple events at once
doesn't need help from Shift or Ctrl modifiers anymore.
- DSSI and VSTi plugins get all their default parameters values reset on
MIDI program change.
- Several major fixes have been applied to the MIDI clip editor,
regarding snap precision and correctness, most specially due on clips
which weren't located on exact bar boundaries.
- Brand new usability feature introduced: mute, solo and monitor
toggling may now be applied to all tracks in session at once, when
issued with either the Shift or Ctrl keyboard modifiers, which will set
or reverse respectively all other tracks state.
- Audio buses plugin chain may be also accessed and edited from the
extended bus management dialog (View/Buses...).
- MIDI meter level default color is now set distinct from the old
lime-green one as in audio level meters.
- MIDI clip editor is now a genuine top-level window, fixing all
keyboard shortcut ambiguities with main application window.
- Mixer splitter panes are now collapsible and optionally hidden.
- Make MIDI instrument patch management a little more sane, as for
preventing the accidental insertion of blank instrument names and
automatic default bank/program selection in track properties.
- All connections are now based exclusively on the textual client and
port names, effective in particular to match MIDI bus ports with
disregard to their volatile numerical identification.
- MIDI file (SMF) header endianess fix (PPC users rejoyce:))
- Record armed tracks aren't muted for playback anymore, as this was a
severe crippling nuisance regarding input monitoring and all mighty user
experience after recording a simple take; for instance, as the bottom
line goes, there's no need to un-arm a track from its record-enabled
state anymore, for just recorded material get heard on immediate
playback; kick on the jam!
- Playhead position overflow fixed on negative MMC STEP commands.
- Thumb-view width proportions now based on minimal slack session length
instead of the auto-extending track-view contents width.
- Optimize audio clip drawing, most specially on zoomed-out levels.
- Bring the audio peak frames into some sort of cache, preventing
recurrent peak frame buffer reallocation and trashing.
Cheers && Enjoy!
