Wholly greetings, Without any further delay, here it goes: Qtractor 0.9.10 (autumn'19) is now released! The shortest and maybe TL;DR change-log for this northern Autumn'19 release goes like this: - Fixed the potential crash-effect in switching MIDI output buses on tracks that are set to show audio output monitoring meters. - Fixed initial session tempo override when importing a standard MIDI file (as reported on issue #230). - An alternate time-signature/meter option is being served to the MIDI clip editor (aka. piano-roll) and allowing for some poly-rythm/meter scenarios on a per MIDI clip basis. - Fixed MIDI "overdub" recording on offset clips. - MIDI bank and program settings now propagating to all MIDI track's clips resp. - Fixed MIDI file format default setting other than SMF Format 0. - Escape key may now be used to reset time and tempo/time-sgnature spin-box controls. - Play-head time and tempo/time-signature controls are now featured in MIDI clip editor toolbars (aka. piano-roll); time display format is also separated from the tracks main application view and defaults to BBT as being most convenient. - All items in the MIDI clip editor's event list are now enabled, selectable and editable, no matter the filter settings for the event views. - Added alternate yet non-official CMake build option. - Improved MIDI clip editor (aka. piano-roll) position and size persistence across session state. - Fix HiDPI display screen effective support (Qt >= 5.6). - Mixer, Connections and MIDI clip editor top-level windows shall have no parent, unless when set as always-on-top tool windows. (REGRESSION) - Make sure compiler flags comply to c++11 as standard. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Linux Audio Conference 2020 : Call for scientific & artistic works

by Linux Audio Conference

The 18th Linux Audio Conference call for participation is open. The conference will take place May 11-13, 2020, at the SCRIME, part of the University of Bordeaux in France. Up-to-date information will be available at the following address : https://lac2020.sciencesconf.org/ Linux Audio Conference is the premier meeting of developers, researchers, and artists developing and using free, libre and open-source audio software, mainly on the GNU/Linux operating system. The conference is part of the Linux Audio consortium. A special event will take part the day before, on Sunday the 10th May 2020: attendants may want to book their week-end. This edition's date has been chosen so that interested parties may be able to attend the International Faust Conference, which will happen in Paris 14-15 May 2020. We kindly invite researchers, developers and artists alike to take part to the event and propose their work. Important information ===================== - Submissions must go through the conference website: https://lac2020.sciencesconf.org. - Submissions must be written in English. - Submissions will be peer-reviewed by a jury of experts with adequate qualifications in regard to the topic of the submission, excluding lightning talks. - Submissions will be present in the proceedings, including workshops, excluding lightning talks. - Submissions can focus on technical, artistic or scientific issues. - Contact address: lac(a)linuxaudio.org - Deadlines (all deadlines are at 23:59 UTC -12:00): * Paper & poster submission deadline: 31/12/2019 * Workshop submission deadline: 31/01/2020 * Notification to authors: 15/02/2020 * Camera-ready deadline: 25/03/2020 * Code jam: 10/05/2020 * Conference dates: 11/05/2020 to 13/05/2020 Call for Papers / Posters / Workshops ===================================== The general themes are audio research and development on Linux systems, & FLOSS (free, libre and open-source) multimedia. We encourage submissions on non-Linux FLOSS operating systems (BSDs, Haiku, Fuschia, IncludeOS, Redox...) as well as non audio-centric works: video, network protocols, performing arts, video games... The 2020 edition has a leading theme: Libre Languages. Papers ------ Paper templates are available to download from here: https://github.com/linuxaudio/lac-paper-templates. The length of a paper is 4 to 8 pages, with up to 5 keywords, and an abstract of 100 to 200 words. The abstract will be published on the conference website once the paper has been accepted. Initial submissions must be anonymized ; please inform us of any potential conflict of interest. The full paper will be made available on the website at the beginning of the conference. Accepted papers will be presented in an oral session. In order for a paper to appear in the proceedings, it must have been presented orally at the conference by at least one of its authors. The length of the presentation is 20 minutes followed by a 5 minutes discussion. Posters ------- LAC2020 accepts submission of posters related to any of the themes mentioned before. We cannot print posters. There is a printing shop located very close to the university which can print a poster from a PDF (Copifac Talence, 548 Cours de la Libération). Workshops --------- LAC2020 accepts workshop proposals. An abstract and a description of the workshop following the paper template (1 or 2 pages max) is required. If the workshop participants need to install any kind of software, please write it plainly in the workshop abstract. Workshops must last at most two hours ; if shorter, please precise the expected duration in the submission so that we can schedule them accordingly. Lightning talks ------------------ Lightning talks last 5 minutes and can be very useful to quickly present your latest software development. They will not be submitted to peer review and can cover peripheral topics, including discussions about the Linux Audio community or other areas of free software. Due to the very short time, if a medium is required, you will be required to submit it : * As slides in PDF format. * As a video file. The medium will be made readily available on a plugged-in computer. Non-exhaustive list of accepted topics -------------------------------------- * Art projects done with free software systems. * Audio architecture of operating systems * Audio plug-ins * Education, teaching * Graphical environments for creation * Hardware support * Interactive Art * Interfaces for musical expressivity * Live coding * Embedded hardware & support (ARM, RISC-V, etc) * Mobile hardware & support (phones, tablets) * Musical production and related tools * Network protocols * Network distribution * New Media Art * Open hardware * Performing arts * Programming languages for creation * Real-time programming languages * Real-time operating systems and kernels * Sensors, human-machine interfaces in a real-time context * Signal and sound processing * Sound spatialisation * Standards, interoperability * Video * Video games Call for Artworks ================= LAC 2020 invites submissions of artistic works involving the use of free, libre and open-source software and/or hardware. Pre-recorded music, interactive installations and live performances are accepted. A jury will select the compositions and installations to be included in the conference program according to artistic merit and technical feasibility. Please be prepared to perform your work yourself and make sure that you have all resources needed to perform your piece (e.g. instruments, props, other performers, etc.). The installations will be located in multiple places, which are described on the website at the following address : https://lac2020.sciencesconf.org/resource/page/id/3 Each place will have a different sound system available. Musical works and installations can address all areas of media art as long as they include some level of audio creation using free software. Examples of accepted works can include: * Acoustic Music * Acousmatic music * Art installations * Electronic Music * Electroacoustic Music * Game in art * Interactive Art * Live code * Mixed Music * Musique concrète * New Media Art * Web and Connected Art Code jam ======== The day before the official beginning of the conference (10th may) will feature a code jam. The goal of the code jam is to provide a space for teams developing Linux audio software to meet in person and discuss development issues in an informal way, as well as introduce new contributors to the various codebases, and overall to perform a live state of the art of audio software on free systems. The code jam will have a topic, which will be disclosed upon opening. It is not mandatory to follow it as it mainly serves to provide inspiration. Starting from Sunday 21:00, a live code session will begin. It is open to everyone. If you plan to participate, please notify us in the registration form with: * The kind of media you plan to use ? (Audio, video, both...) * The output ports are available on your hardware ? (HDMI, VGA, ...) ------------------ We thank you in advance for your participation and kindly invite you to share this call to any interested organization or person you may be aware of. With our best regards, The Linux Audio Conference team

JACK2 v1.9.13 release

by Filipe Coelho

A new version of JACK2 has just been released. You can grab the latest release source code at https://github.com/jackaudio/jack2/releases. The official changelog is: - Meta-data API implementation. (and a few tools updated with support for it) - Correct GPL licence to LGPL for files needed to build libjack. - Remove FreeBoB backend (superseded by FFADO). - define JACK_LIB_EXPORT, useful for internal clients. - Mark jack_midi_reset_buffer as deprecated. - Add example systemd unit file - Signal to systemd when jackd is ready. - Set "seq" alsa midi driver to maximum resolution possible. - Fix loading internal clients from another internal client. - Code cleanup and various fixes. (too many to mention here, see git log for details) This release is focused on meta-data support, and this is why it took so long. There might be odd cases here and there and a few bugs, as it is often the case for all software... So please make sure to report back any issues! Special thanks goes to Rui Nuno Capela for the initial pull-request regarding meta-data. There was some work needed afterwards, but that was the biggest hurdle and motivation needed for a new release. :) There are still no updated macOS or Windows builds, those will be handled at a later date. Current plan is to have JACK1 feature-parity first (only a2jmidid and zita internal clients missing now), and afterwards merging examples/tools and header files to be shared between JACK1 and JACK2. The situation regarding development of JACK and JACK1 considered legacy has not changed since last release 2 years ago. See https://jackaudio.org/news/#jack2-v1912-release-and-future-plans for more information. PS: I will be in Cologne for https://www.sonoj.org/ giving a talk about "Past, Present and Future of JACK". There is no registration fee, so please feel free to come by and say hello! :)
