Dear all,
Linux Audio Monthly Round-Up #3 – October 2010 has been published:
http://www.linuxaudio.org/node/118
Many thanks again to the people @ linuxmao.org. And my apologies that it
took a bit longer yet again. I had to clean up thousands of comments
because I accidentally enabled commenting on Round-Up #2...
Best,
Jeremy
jack_mixer is a GTK+ JACK audio mixer app with a look similar to its
hardware counterpart. It has lot of useful features, apart from being
able to mix multiple JACK audio streams. It is licensed under GPL
version 2 (or later).

* Added 'Edit .. channel' submenus
* Set a default 'apply' button in channel properties
* Fixed creation of mono channels
* Removed bad crackling when changing the volume through MIDI
* Moved back to polling for MIDI events, to avoid the need for threads
* Changed to use backward compatible call to gobject.timeout_add (#14999)
* Updated not to fail if we can't get lash server name

Virtual MIDI Piano Keyboard is a MIDI events 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.
Changes
* Option to represent MIDI velocity as highlight color tint
* Tool shortcuts, with a shortcuts editor dialog borrowed from Qtractor
* Language menu, allowing to select and change languages on the fly
* New "About Translation" dialog. Linux translation files moved to the program
data directory
* Fixed knobs and sliders tool-tip positions
* Allow to trigger defined but hidden keys
* Process incoming controller events: all sounds/notes off, and reset
controllers.
* Translations updated

Change-log:
- While moving multi-selected MIDI events around the clip editor (aka
piano-roll), with help of keyboard arrow keys, that is, was not clear
which one was the so-called "anchor" event, the one which positioning
gets honored for snap-to-beat business. Not anymore: the anchor event
now defaults to the earliest in time or the one the user's last
point(-click)ed.
- MIDI control observer pattern implementation has sneaked in, making it
ready for the so-called and long-awaited "MIDI Learn" feature and
arbitrary MIDI controller assignment, for plugin parameters in particular.
- MMC DEFERRED PLAY doesn't cause transport state to stop if currently
rolling (mitigating bug #3067264).
- Audio clip merge processing might have been skipping a few initial
frame blocks, now fixed.
- Clip selection and plugin parameter hash optimization.
- Anti-glitch audio clip macro fade-in/out fixed again.
- New clip fade-in/out slopes (curves) are introduced, partially adapted
and refactored from those easing equations of Robert Penner's fame.
- Clip fade-in/out non-linear slopes are now shown as actual WYSIWYG curves.
- Escape key now closes generic plugin widgets as ever found usual
elsewhere.
- Picking nits: unselect current track when clicking on any gray empty
area, also accessible from a new menu item: Track/Navigate/None.
- A nasty and deadly MIDI resolution overflow has been finally fixed,
allowing for long MIDI sequences (1h+) to load correctly on 32bit
machines from now on (was perfectly fine on 64bit though).
- MIDI editor selection hash optimization in face of reasonably huge
event sequences.
- MIDI controller mapping finally refactored to support some other MIDI
event types than just CC (0xBn) ones.
- Nitpicking fix: corrected main track-list (left pane) display when no
track is currently selected.
- libX11 is now being added explicitly to the build link phase, as seen
necessary on some bleeding-edge distros eg. Fedora 13, Debian 6. (fixing
bug #3050944).
- New audio metronome bar and beat sample gain options.
- Progressively, the observer pattern is being finally introduced,
targeting all potentially automation controls and widgets as plain
ground-zero for the (ultra-)long overdue automation feature.
- MIDI controller mapping of still non-existing tracks were being
implicitly assigned to the last, highly numbered, existing track. Now fixed.
- Moving from old deprecated Qt3'ish custom event post handling into
regular asynchronous signal/slot strategy.
- Muting/soloing tracks while playback is looping was leaving current
audio clip out-of-sync whenever that same track is later un-muted on any
other preceding clip. Now hopefully fixed.
- MIDI Clock support makes its first appearance.
- All tempo (BPM) calculations are now compliant to the MIDI
conventional equivalence between beat and quarter note (1/4, crotchet)
as common standard time division.
- Automatic audio time-stretch option is not enabled by default anymore.
- Standard warning Apply button is now only shown when dismissing dialog
changes are actually valid.
- Make sure non-dedicated metronome and player buses are properly reset
and reopen when changing regular audio buses (hopefully fixing bug item
#3021645 - Crash after changing audio bus).
- Hopefully, an outrageously old bug got squashed away, which was
causing random impromptu crashes, most often when importing audio clips
while looping and play-head is any near the loop end point.
- General standard dialog buttons layout is now in place.
- Fixed main track view off-limits play-head positioning.
- Main tool-bar Time and Tempo spin-boxes, may now have their colors
correct, as for most non-Qt based theme engines (ie. Gnome). Green text
on black background has been and still is the the intended aspect design ;)
- MIDI file import and internal sequence representation has been changed
to be inclusive on all bank-select (CC#0,32) and program-change events
which were previously discarded while honoring MIDI track properties.
Interleaved SysEx events are now also preserved on their original
sequence positions instead of squashing a duplicate into the MIDI bus
SysEx setup.
- Attempt to include the VeSTige header by default, as for minimal VST
plugin support.
- JACK transport support has been slightly rewritten, in fact the sync
callback is now in effect for repositioning.
- The MIDI clip editor (piano roll) widget won't be flagged as a tool
window anymore.
- A tempo adjustment tool is making inroads from the menu, as
Edit/Clip/Tempo... (factory shortcut: F7).
- Audio tracks auto-monitoring is now effective on playback.
- Make sure to ask whether a dirty MIDI clip should be saved, upon
resizing or stretching its edges (fixes bug #3017723).
- Backward and Forward transport commands are now taking additional
stops on loop points.
- Attempt to optimize track solo/mute redundant transactions, in special
regard to MIDI track events which were being duplicated on soloing and
temporarily muted on unsoloing.
Cheers && Enjoy (be happy!)

The ON2: Test Signals festival will bring together software developers
and radio practitioners to demonstrate, discuss and develop new ways of
applying software to radio on Friday 22 October and Sat 23 October 2010
at Direktorenhaus, Berlin.
Appearing at the festival will be former BBC radio futurologist James
Cridland, NATO Information Operations Consultant David Bailey MBE, Lukas
Weiss of UNIKOM (Switzerland's free radios association) and Chris Weaver
from Resonance FM. Mozilla Drumbeat, Creative Commons, Liquidsoap, MPD
and 64 Studio will also be represented amongst over 30 speakers and
organisations.
Audiences will be able to set radio free with Campcaster, map the city
with Radio Aporee, stream net-radio with Liquidsoap and hack broadcast
technologies with RadioDNS in a series of free workshops. Sign-up is
free via <http://www.testsignals.org> where the full programme
information can be found.
In association with GTZ, Germany's federal organisation for sustainable
development, the festival will also hold a special preview event with
politicians and policy makers on Thursday 21 October. On Saturday 23
October, festival partners reboot.fm will hold an Allstars Afterparty in
.HBC Berlin featuring some of Berlin's hottest radio and musical talent.
The festival is organised by Sourcefabric. reboot.fm, Berlin's free
cultural radio station, and user-generated radio pioneers Open Broadcast
from Switzerland are official partners of the festival. The festival is
also an official satellite event of transmediale, festival for art and
digital culture, and is the first in a series of open-source workshop
events supported by the Free Culture Incubator. The festival is also
partnered by Mute magazine, a magazine dedicated to exploring culture
and politics after the net.
