Hello FLOSS audio people!
I'm proud to announce the new release of jack_mixer version 15!
jack_mixer is a GTK+ JACK audio mixer app with a look & handling similar
to hardware mixing desks.
Please visit the project's homepage at rdio.space/jackmixer for more
You can find the new release on Github at:
**Important change:** 'jack_mixer' now uses [meson] for building and
installation. See 'INSTALL.md' in the source for new build instructions.
* A global setting for default project file path was added and can be
changed in the preference dialog.
The default value is '$XDG_DATA_HOME/jack_mixer' (which is normally
* A "Recent projects" menu was added, to allow loading recently used /
saved projects more quickly.
* Direct channel output ports are now optional and can be enabled /
disabled in the channel preferences dialog.
* Ctrl+left-click on the mute ("M") or solo ("S") channel buttons now
activates exclusive mute resp. solo.
* A man page for 'jack_mixer' was added.
* 'jack_mix_box' now supports the '-p|--pickup' command line option to
enable MIDI pickup mode, to prevent sudden volume or balance value
* Activating the solo function on an input channel could cause its
output signal be sent to the monitor outputs instead of the signal
from the channel, which had monitoring activated.
* Volume and balance level and mute and solo state changes originating
from the UI now send the correct assigned MIDI CCs, allowing for MIDI
feedback to controllers. Same for changes originating from reception
of assigend MIDI CCs.
* The handler for right-clicking the input channel mute/solo buttons,
was accidentally removed and is now re-instated.
* Creating a new output channel assigns it a randomly chosen color,
which can be changed in the new channel dialog (used to work
some releases ago, but was broken at some point).
* The 'jack_mix_box' command line options '--help' and '--stereo'
erroneously required an argument.
* Saving the current project on reception of the 'SIGUSR1' signal, which
is a requirement for LADISH level L1 support, was broken in version
* When re-ording channels via drag-and-drop, the order of the edit /
remove channel menu items were not updated.
* When creating an output channel, it could happen that the initial
channel volume would ranmdomly be set to -inf or 0 dB, regardless of
what was selected in new channel dialog.
* The minimum supported Python version is now 3.6.
* The 'jack_mix_box' command line usage help message was improved.
* The channel strip buttons (solo, mute, etc.) now have more distinctive
colors when activated or the mouse hovers over them.
* The balance slider step size was increased slightly so right-clicking
the slider changes the value more rapidly.
* When using the "Save as..." function, 'jack_mixer' now sets the
default filename and directory for file chooser to the last ones used.
* A window title was added to the preferences dialog.
* MIDI control for mute and solo now interprets control value 0-63 as
off and 64-127 as on, instead of toggling the state on reception of
any controller value.
Project infrastructure and internals:
* The 'jack_mixer_c' Python extension module, which was originally
implemented in hand-written C code using the PYTHON C API, was
replaced with the '_jack_mixer' extension module implemented in
Cython, which generates the C code in '_jack_mixer.c'.
* The autotools build toolchain was replaced with a build setup using
meson, which improves build times and maintainability markedly. See
the file 'INSTALL.md' for updated build and installation instructions.
* A build option to allow buidling only 'jack_mix_box' was added
* All Python code was re-formatted with [black].
* All errors and warings reported by [flake8] were fixed or are
expressively and selectively ignored.
* The file 'version.py' is now generated from the version set in the
project definition in the top-level 'meson.build' file, leaving this
as the only place where the version number needs to be updated before
* The 'NEWS' file was renamed to 'CHANGELOG.md' and converted to

Ladies and Gentlemen,
hereby the Laborejo Software Suite releases updates for its programs in
the hope to be useful in your musical toolbox.
You can now download Patroneo version 2.1.0 .
All software is released under GPLv3.
Patroneo (Esperanto: /Pattern/) is an easy to use, pattern based midi
sequencer, a program that sends digital "notes" to software instruments
such as synthesizers and samplers.
* Full Undo/Redo
* Add track groups, which double as midi bus. This enhances overview for more complex projects.
* Add option to follow the playhead in pattern view (or not), required by the much longer patterns. Also better scrolling and playhead is always visible now.
* Add option to change the midi channel for a track in the tracks context menu.
* Add View-Menu with options to maximize the two editor areas.
* Add advanced feature for a global rhythm offset, meant for Jack-Transport. Allows the whole piece to begin later on the jack-timeline.
You can find all releases as sources here. Also check your distribution
for packages in a few days after this announcement, please.

Call for Submission of Papers and Extended Abstracts
26th International Conference on Auditory Display
25-28 June 2021
THEME: “SOUNDING BOARD”
In addition to being part of the resonating chamber in a musical
instrument, the term sounding board is also a metaphor for a channel
through which ideas are discussed and disseminated. ICAD, established in
1992 has, through its 25 conference meetings, shared over 1,150 papers with
the auditory display community. This year, the conference will offer itself
as a sounding board for the community, allowing time to pause and reflect
on the history of auditory display research, review how research has
changed throughout the years, and discuss future areas of inquiry as well
as how to adapt our research during these challenging times. Therefore, the
ICAD 2021 committee is seeking full papers, abstracts, concert pieces,
demos, installations, workshops, and tutorials from across the full
spectrum of auditory display research and practice. From discussions and
reflections on the history of auditory display research with a view to
generating new ways of thinking about how we as practitioners should go
about things, to speculative ideas or news of late-breaking work,
submissions are sought across all the categories. We are particularly
interested in hearing from researchers who have never considered themselves
to be part of the community before, or whose work sits at the periphery of
Full Papers - March 31st
Abstract Only Submissions (no paper published) - April 30th
Workshops/Tutorials/Demos - April 30th
Live Performances/Installations - April 30th
Doctoral Consortium/Thinktank -April 30th

instructions, and additional conference information please visit

First held in 1992, ICAD is a highly interdisciplinary conference with
relevance to researchers, practitioners, artists, and graduate students
working with sound to convey and explore information. The conference is
unique in its specific focus on auditory displays and the range of
interdisciplinary issues related to their use. Like its predecessors, ICAD
2021 will be a single-track conference, open to all, with no membership or
