I am pleased to announce the release of Composite 0.006.1. This is a bug-fix release. ABOUT ----- Composite is (or, will be) a software application/system for real-time, in-performance sequencing, sampling, and looping. Currently the main feature is the LV2 Sampler that supports Hydrogen drumkits. CHANGES ------- * Fix FTBFS: t_AudioPort test missing link to QtCore * Fix FTBFS Song.cpp: Replace using of QString(int) with QString(const char*) * LV2 Sampler: Initialize QCoreApplication * LV2 Sampler: Fix crash by moving Logger instance to module level * LV2 Sampler: Check LV2 Event types and add extension meta-data * tests: t_AudioPort had a degenerate test * tests: t_SeqScript now passes (was failing as dev reminder) * Replace -lQtCore with ${QT_LIBRARIES} in build system STATUS ------ Composite is a project with a large vision. Here is the status of the different components: composite-gui: Alpha (i.e. "a broken version of Hydrogen") compoiste_sampler (LV2): production/stable, no GUI libTritium: Not a public API, yet. LINKS ----- Composite: http://gabe.is-a-geek.org/composite/ Plugin Docs: file:///home/gabriel/code/composite-planning/plugins/sampler/1 Tarball: http://gabe.is-a-geek.org/composite/releases/composite-0.006.tar.bz2 Git: http://gitorious.org/composite git://gitorious.org/composite/composite.git HOW TO USE THE PLUGIN --------------------- To use the plugin, you need the following: * A program (host) that loads LV2 plugins. * A MIDI controller. * An audio output device. :-) The following LV2 hosts are known to work with this plugin: Ingen http://drobilla.net/blog/software/ingen/ ardour3 (alpha) http://ardour.org/ lv2_jack_host http://drobilla.net/software/slv2/ zynjacku http://home.gna.org/zynjacku/ If you don't have a hardware MIDI controller, I suggest using jack-keyboard (http://jack-keyboard.sourceforge.net/). The first time you run the sampler, it will create a file ~/.composite/data/presets/default.xml, which will set up presets on Bank 0 for the two default drum kits (GMkit and TR808EmulationKit). Sending MIDI PC 0 and PC 1 will switch between the two kits. See composite_sampler(1) for more information on setting up presets. ACKNOWLEDGMENTS --------------- With this release, I would especially like to thank: Alessio Treglia - For dutifully reporting bugs, submitting patches, and *patiently* waiting for me to review them. Paul Davis - For working with me on the crashes that were discovered on ardour3 alpha. Peace, Gabriel M. Beddingfield

[LAA] Reminder: Call for Abstracts: Versatile Sound Models for Interaction in Audio–graphic Virtual Environments Workshop at DAFx-11, Ircam, Paris

by Diemo Schwarz

*REMINDER* deadline for submission of abstracts is Sunday July 17. If you need an extension, please contact us before Monday. Call for Abstracts: Versatile Sound Models for Interaction in Audio–graphic Virtual Environments: Control of Audio-graphic Sound Synthesis Workshop @ Conference on Digital Audio Effects DAFx-11 Friday September 23, 2011 at Ircam, Paris The use of 3D interactive virtual environments is becoming more widespread in areas such as games, architecture, urbanism, information visualization and sonification, interactive artistic digital media, serious games, gamification. The limitations in sound generation in existing environments are increasingly obvious with current requirements. This workshop will look at recent advances and future prospects in sound modeling, representation, transformation and synthesis for interactive audio-graphic scene design. Several approaches to extending sound generation in 3D virtual environments have been developed in recent years, such as sampling, modal synthesis, additive synthesis, corpus based synthesis, granular synthesis, description based synthesis, physical modeling... These techniques can be quite different in their methods and results, but may also become complementary towards the common goal of versatile and understandable virtual scenes, in order to cover a wide range of object types and interactions between objects and with them. The purpose of this workshop is to sum up these different approaches, present current work in the field, and to discuss their differences, commonalities and complementarities. Accepted abstracts will be invited to submit an extended version to a special issue of the Springer Journal on Multimodal User Interfaces (JMUI) or SpringerOpen EURASIP Journal on Audio, Speech, and Music Processing. Detailed information about the workshop can be found here: http://www.topophonie.fr/event/3 http://dafx11.ircam.fr/?page_id=224 The workshop is free for attendants of the DAFx conference and for non-DAFx-attendants by invitation. Registration to the DAFx conference can be found here: http://dafx11.ircam.fr Call for Abstracts ------------------ Abstracts (max. 1 A4/Letter page, PDF format) on the topics of the workshop should be sent by July 17 to Diemo Schwarz (schwarz(a)ircam.fr) The submissions will be reviewed by a program committee and accepted communications will be given at the workshop. The authors will be notified at the latest end of July, 2011. Important Dates --------------- * July 17, 2011: Abstract Submission Deadline * July 31, 2011: Notification of Acceptance * September 23, 2011: Workshop Program Chairs -------------- Roland Cahen, ENSCI-les Ateliers Diemo Schwarz, IRCAM Christian Jacquemin, LIMSI-CNRS & University Paris Sud 11 Hui Ding, LIMSI-CNRS & University Paris Sud 11 Program committee ----------------- Nicolas Tsingos (Dolby Laboratories) Lonce Wyse (National University of Singapore) Andrea Valle (University of Torino) Hendrik Purwins (University Pompeu Fabra) Thomas Grill (Institut für Elektronische Musik IEM, Graz) Charles Verron (McGill University, Montreal) Cécile Le Prado (Centre National des Arts et Metiers CNAM) Annie Luciani (Ingénierie de la Création Artistique ICA, ACROE) Topics in detail ---------------- Which other and better alternatives to traditional sample triggering do exist to produce comprehensive, flexible, expressive, realistic sounds in virtual environments? How to produce rich interaction with scene objects such as physically informed models for contact and friction sounds etc? How to edit and structure audio–graphic scenes otherwise than mapping one event to one sound? There is no standardized architecture, representation and language for auditory scenes and objects, as is OpenGL for graphics. The workshop will treat higher level questions of architecture and modeling of interactive audio-graphic scenes, down to the detailed question of sound modeling, representation, transformation and synthesis. These questions cannot be detached from implementation issues: novel and hybrid synthesis methods, comparison and improvement of existing platforms, software architecture, plug-in systems, standards, formats, etc. New possibilities regarding the use of audio descriptors and dynamic access to audio databases will also be discussed. Beyond these main questions, the workshop will cover other recent advances in audio-graphic scene modeling such as: * audio-graphic object rendering, and physically and geometrically driven sound rendering, * interactive sound texture synthesis, based on signal models, or physically informed * joint representation of sound and graphic spaces and objects, * sound rendering for audio-graphic scenes: * level of detail, which is a very advanced concept in graphics, but is rarely treated in audio. * representation of space and distance, * masking and occlusion of sources, * clustering of sources * audio-graphic interface design, * sound and graphic localization, * cross- and bi-modal perceptual evaluations, * interactive audio-graphic arts, * industrial audio-graphic data: * architectural acoustics, * sound maps, * urban soundscapes... * platforms and tools for audio-graphic scene modeling and rendering, These areas are interdisciplinary in nature and interrelated. New advancements in each area will benefit the others. This workshop will allow to exchange the latest developments and to point out current challenges and new directions. -- Diemo Schwarz, PhD -- http://diemo.concatenative.net Real-Time Music Interaction Team -- http://imtr.ircam.fr IRCAM - Centre Pompidou -- 1, place Igor-Stravinsky, 75004 Paris, France Phone +33-1-4478-4879 -- Fax +33-1-4478-1540

[LAA] xjadeo 0.6.1 released

by Robin Gareus

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 xjadeo is a video player that synchronizes to an external time-source. http://xjadeo.sf.net/ After half a year of being stuck at release-candidate-7 the 0.6.0 went out quietly last week. version 0.6.1 - released today - fixes a small bug (russian and greek translations were not installed), adds JACK-Session Support to xjadeo [1] and makes use of JACK's new(er) latency compensation API. As a reminder: version 0.6.0 introduced support for win32, features a complete manual rewrite/overhaul, includes long overdue QT3->QT4 port of the GUI, adds support for parsing LTC timecode from audio, switches to more user-friendly default settings and support for newer versions of ffmpeg/libav* amongst many other small details (see the changelog). Thanks to Alessio Treglia (debian packaging, bug reports), Alexandre Prokoudine (testing, bug reports, Russian translation), Geoff Beasley (testing and Manual contributions), Michales Michaloudes (Greek translation) and Natanael Olaiz (bug squashing). - -=- [1] More on JACK-Session support: The [win32 and OSX] binaries available from sf.net do _not_ include JACK-Session support, yet. On GNU/Linux (or self-compiled binaries for other OS) the complete state of xjadeo is saved for each session, but the optional GUI (qjadeo) is not restored. However, [re-]launching the GUI will [re-]attach it to an already running xjadeo instance. Known issue: If multiple instances of xjadeo are running, it is only possible to re-attach to all of them by setting the xjadeo session-ID using the XJREMOTE environment variable _before_ launching the qjadeo remote-control GUI. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEARECAAYFAk4d55UACgkQeVUk8U+VK0LLZwCcC6HKKikjALUZJ/3OGpdvE4sJ vOwAoL6oXQWh/1QB28aM0ppYNTTOdrQu =qEq2 -----END PGP SIGNATURE-----

[LAA] QMidiArp 0.4.2 released

by Frank Kober

Hi all, Great feedback from some users, especially Louigi Verona, Sascha Schneider and Jeremy Jongepier have kept the inspiration level up, and some bugs could be squeezed since the last release. Louigi has even used QMidiArp in Live sessions that you can now listen to on the qmidiarp website at http://qmidiarp.sourceforge.net/qmidiarp_demos_en.html I'd also like to thank Nedko again for great discussions and answers in most cases Two major issues had been addressed in a provided patch, but other small ones are now done in this release. But there are even some new features, most of them inspired by you guys: qmidiarp-0.4.2 (2011-07-10) New Features o LFO wave lengths up to 32 bars for very low frequencies o Groove Settings and LFO & Seq resolutions now also MIDI-controllable o One-click duplication of LFO and Seq modules o Option to add new modules in muted state o Vertical Zoom switch for Seq module display o ToolBars can be positioned vertically o Nested arrangement of modules allows more flexible layouts Fixed Bugs o 0.4.1-patch had been available for the following two: o Jack Transport sync arbitrarily stopping with only arp modules o Instability with ALSA clock with only Seq and LFO modules o Faster response to Jack Transport state changes o Incorrect response to two Seq sliders General Changes o Jack Transport sync uses jack process callback not sync callback Enjoy! ------------------------------------------------------ http://qmidiarp.sourceforge.net/ http://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.4.2/ ------------------------------------------------------

[LAA] QjackCtl 0.3.8 released!

by Rui Nuno Capela

Howdy! JACK Session versioning is quite simply the most interesting new feature for this release. It's optional but enabled by default. One can just turn it off and keep the bad old take-no-prisoners behavior :) Never is too late, QjackCtl 0.3.8 has been released! Enjoy. Website: http://qjackctl.sourceforge.net Project page: http://sourceforge.net/projects/qjackctl Downloads: - source tarball: http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.8.tar.gz - source package (openSUSE 11.4): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.8-2.rncbc.suse114.sr… - binary packages (openSUSE 11.4): http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.8-2.rncbc.suse114.i5… http://downloads.sourceforge.net/qjackctl/qjackctl-0.3.8-2.rncbc.suse114.x8… Weblog (upstream support): http://www.rncbc.org License: QjackCtl is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Debugging stacktrace now applies to all working threads. - Session "Save" button now a drop-down menu, replacing the session save type combo-box/drop-down list selection. Also, an early session directory versioning/numbering scheme is now in place, although optional. - Probable fix to debian bug report #624198 - segfault when pressing the stop button (by Grant Adrian Diffey, after a patch from Adrian Knoth, thanks). - Desktop environment session shutdown (eg. logout) is now tapped for graceful application exit, even though the main window is active (visible) and minimizing to system tray is enabled. Both were causing first shutdown/logout attempt to abort. Not anymore, hopefully ;). - Make sure all activated patchbay definition files are in their complete and absolute directory path forms. - Connections refresh button now does an immediate and true reconstruction of all clients and their respective ports and connections, unconditionally. - Command line server start option (-s, --start) is now made independent from configuration setup option (cf. Setup/Misc /Start JACK audio server on application startup). - Now handling cable socket types properly to let patchbay definitions work correctly, whenever having sockets with the very same literal name (twisted from patch #3183467, by Karsten, thanks;). - Abrupt focus behavior when any of the keyboard modifiers (Shift, Ctrl, Alt, Caps Lock) is hit while on Connections client/port aliases editing (rename) has been fixed. - Russian (ru) translation updated (by Alexandre Prokoudine). - Added include "errno.h" alegedly missing for BSD style systems (applying patch for bug #3126091). Cheers && Enjoy -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
