The first unified LV2 release, LV2 1.0.0, is out. This release merges the previous lv2core package with all the official extension packages, as well as example plugins, lv2specgen, and additional data. From a developer point of view, the biggest change is that all LV2 API headers can be used by simply checking for the single pkg-config package "lv2" (for compatibility the previous "lv2core" package is still installed). Implementations are encouraged to abandon the "copy paste headers" practice and depend on this package instead. With this release, several new extensions have become stable that together greatly increase the power of LV2: atom, log, parameters, patch, port-groups, port-props, resize-port, state, time, worker.

QMidiArp-0.5.2 released

by Frank Kober

Hi, QMidiArp 0.5.2 has just seen the light of the day. It brings mainly two improvements. One is a comeback, that of tempo changes on the fly, and that now includes also tempo changes of a potential Jack Transport master. Also the Jack Transport starting position is finally taken into account, so that QMidiArp should be in sync also when starting the transport master not at zero. The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen! Note that for compiling in NSM support you will now need liblo as dependency. Enjoy, and enjoy LAC in Graz this year Frank ________________________________ QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. Everything is on http://qmidiarp.sourceforge.net qmidiarp-0.5.2 (2013-05-09) New Features o Tempo changes are again possible while running, both manually or by a Jack Transport Master o Jack Transport position is now taken into account when starting, QMidiArp used to start always at zero o Muting and sequencer parameter changes can be deferred to pattern end using a new toolbutton o Modules in the Global Storage window have mute/defer buttons o Global Storage location switches can be set to affect only the pattern o Non Session Manager support with "switch" capability (thanks to Roy Vegard Ovesen) General Changes o NSM support requires liblo development headers (liblo-dev package)

GlassCoder v0.5.0

by Fred Gleason

I’m pleased to announce the initial public beta release of GlassCoder, a minimalist JACK live encoder client for Icecast and Shoutcast streaming servers. GlassCoder is available under the GNU Public License version 2. Some features available in this initial beta release: Support for Icecast (v2) and Shoutcast (v1) streaming audio servers Support for streaming MPEG Layer 3 (‘MP3’) audio Support for the JACK Audio Connection Kit (http://www.jackaudio.org) GlassCoder is a ‘minimalist’ client in the sense that it utilizes no GUI or configuration file components whatever; its entire ‘user interface’ consists of a command-line invocation, making it particularly well-suited for use cases where the encoder is driven by an external system, such as an automation system or script. Full documentation is provided by the included man page. Further information and download links are available at https://github.com/ElvishArtisan/GlassCoder Cheers! |-------------------------------------------------------------------------| | Frederick F.

Qtractor 0.6.0 - The Byte Bald Beta release!

by Rui Nuno Capela

Once again, it's springtime. Once again, the planet revolved and stepped forward against its mother star. Hence the three bees release... it won't be that far fetched if you find this naming a deliberate pun riddle indeed--the wise will know already while the clueless will get it sudden in a couple of days ;) Well, no big surprises nor earthshaking features are being here pitched then, just some small and otherwise humble improvements and fixes and what not. Nevertheless and not just for the record that is, it marks the day of a long overdue and severely procrastinated beta phase release. Whatever. It's dang official now: one step closer to omega, no doubt ;) Contrary to, maybe, newer generations, I always strive to say the least. As to say about literal face-value meaning, as written and read on timeless textbooks, it's all left in between the lines or, this part is the one I like most, left over as an exercise--in some kind of healthy masochism, perhaps :). No wonder, Qtractor 0.6.0 (byte bald beta) is now released! Release highlights: * Plugin automation high resolution option (NEW) * Plugin 'About' page (NEW) * Native DE dialogs option (NEW) * Follow play-head slack time (NEW) * MIDI RPN/NRPN 14-bit controllers input (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.6.0.tar.gz - source package (openSUSE 13.1): http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.s… - binary packages (openSUSE 13.1): http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.i… http://downloads.sourceforge.net/qtractor/qtractor-0.6.0-10.rncbc.suse131.x… - quick start guide & user manual (outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf - help wanted (on Qtractor Wiki ;)) http://sourceforge.net/p/qtractor/wiki Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - New user option added: on whether to save plugins automation values with higher resolution as possible, using 14-bit NRPN: cf. View/Options.../Plugins/Experimental/High resolution plugin automation (default=off). - Generic native plugin dialogs now shows an additional "About" last page where authorship credits are due. - A new user preference option is now in place for whether to use desktop environment's own native file requester/browser dialogs (View/Options.../Display/Dialogs/Use native dialogs). - A bit of slack have been introduced to put "Follow Playhead" (aka. auto-scroll view mode) on hold, while doing in-flight selection edit moves. - Fixed some user interface related annoyances while on the MIDI Controllers mappings (ie. View/Controllers...). - Fixed port origin on MIDI RPN/NRPN 14-bit controllers input. - A discretionary plug-in unique identifier have been devised for when more than one from the same type are inserted on a bus or track chain, avoiding destructive clashing of automation data. - Horizontal scrolling shift+mouse-wheel direction now reversed. - LV2 Dyn(amic)-manifest support is now optional (default=off); cf. View/Options.../Plugins/Experimental/LV2 Dynamic Manifest support). - The following options, although decieved on View/Options... as global configuration options, were always and still are proper session instance properties: (JACK) Transport mode, MMC mode, MMC device, MIDI SPP and MIDI Clock modes, are now shown there reflecting the current open session state. - A couple of run-time circumventions have been hacked in, both strictly related to when NSM session management is in charge: 1) the new session template feature is disabled (was aborting initial NSM new client additions); 2) the native (as from the desktop environment eg. KDE) file browser/requester dialogs are disabled (were taking too long to list the current directory on first time invocation). - Update current automation/curve nodes selection while changing horizontal (time axis) zoom levels. - One liner's attempt to make it consistent behaviour on resizing and moving multiple selected notes or events while on the MIDI clip editor (aka. piano-roll; after a ticket request from Daniel MacDonald aka. danboid, thanks). - Introducing tiny quarter-note/crotchet/seminima/beat icon on all snap-to-beat selection items get a new icon :). - Corrected some audio buffering boundary conditions that were causing dead-loops/freezes while merging some audio clips. - Session auto-save period was chronically reduced to one third of its user setting; non critical but fixed now. See also: http://www.rncbc.org/drupal/node/772 See you all on LAC2014@ZKM-Karlsruhe! and have a happy new springtime, cheers! Enjoy && yet again, have (lots of) fun. -- rncbc aka Rui Nuno Capela

ANN: New Pd-L2Ork x86_64 and Raspberry Pi 20140319 release candidate

by Ivica Ico Bukvic

Apologies for x-posting. It is my great pleasure to announce immediate availability of the latest Pd-L2Ork, its K12 module, as well as the latest version of Pd-L2Ork for the Raspberry Pi platform that includes comprehensive set of objects for sensing, including GPIO with pulse-width-modulation support, and analog sensor monitoring support (via MCP3008 A/D chip and SPI module). In addition to a slew of bug-fixes and improvements, pd-l2ork's structures have seen a significant overhaul (thanks to contributions from Jonathan Wilkes and others) now supporting a majority of the SVG spec and allowing for some powerful manipulations of structs inside pd patches. Please note that the structs are still under development, so some instabilities remain. Other notable Changelog Highlights for this release include: *new drawimage and drawsprite structs *improved classinfo, canvasinfo, and pdinfo objects *proper queuing for all iemgui objects and other improvements *New preferences dialog *New customizable arrays and jump-on-click ability *UI themes *Improved sanity checks for graph-on-parent patches *over a hundred of other bug fixes and improvements For a complete list of changes please consult the attached git-extracted changelog. The new release is accompanied by a comprehensive documentation on how to connect RPi to the computer as well as run and configure Pd-L2Ork (and its K12 module) for operation on RPi. In addition, as part of this release, the regular Pd-L2Ork install instructions have been also streamlined to make them easier to navigate. For those in Virginia Tech area, the new release candidate will be showcased at the upcoming Institute for Creativity, Arts, and Technology community meeting this Friday 830-930am in ICAT Sandbox. For more info visit: http://l2ork.music.vt.edu/main/?page_id=56 (x86_64 version with updated how-to) http://l2ork.music.vt.edu/main/?page_id=2288 (Raspberry Pi version download and how-to) Obligatory screenshots: http://l2ork.music.vt.edu/main/?page_id=2554 ABOUT L2Ork A contemporary intermedia ensemble, L2Ork, thrives upon the quintessential form of collaboration found in the western classical orchestra and its cross-pollination with increasingly accessible human-computer interaction technologies for the purpose of exploring expressive power of gesture, communal interaction, discipline-agnostic environment, and the multidimensionality of arts. In addition to furthering the artistic exploration of the newfound genre, the ensemble's particular focus is on integration of Taiji (Tai Chi) choreography into its performance practice as well as its philosophy. Founded by Dr. Ivica Ico Bukvic in May 2009, and since 2014 co-directed with Dr. Charles Nichols, L2Ork is a part of the interdisciplinary initiative by the Virginia Tech Digital Interactive Sound & Intermedia Studio (DISIS) and the signature initiative of the newfound Institute for Creativity, Arts, and Technology (ICAT). As the world's first Linux-based laptop orchestra L2Ork offers optimal infrastructure for creative research at minimal cost. By providing a seamless integration of arts and sciences it is in part designed to bridge the gap between STEM (Science, Technology, Engineering, Math) and the Arts, with particular focus on K-12 (Kindergarten to 12th grade) education. http://l2ork.music.vt.edu http://www.facebook.com/L2Ork ABOUT Pd-L2Ork Pd-L2Ork is a Linux-centric fork of the legendary Pure-Data. With over three years of development and 700 new features, bug-fixes, and improvements, its focus is primarily on the laptop orchestra environment, and more specifically L2Ork setup. In 2012 Pd-L2Ork introduced unique K-12 educational module, offering GUI-centric granular approach to learning Pd/Max-like programming environments using a collection of abstractions geared towards K-12 students. Most recently, Pd-L2Ork is also supporting Raspberry Pi platform, paving way towards sub-$100 laptop orchestra instruments. QUESTIONS & INQUIRIES http://l2ork.music.vt.edu/main/?page_id=35 Best wishes, Ivica Ico Bukvic, D.M.A. Composition, Music Technology Director, DISIS Interactive Sound & Intermedia Studio Director, L2Ork Linux Laptop Orchestra Head, ICAT IMPACT Studio Virginia Tech Dept. of Music - 0240 Blacksburg, VA 24061 (540) 231-6139 (540) 231-5034 (fax) ico(a)vt.edu http://www.music.vt.edu/faculty/bukvic/

aubio 0.4.1

by Paul Brossier

Hi all, A new version of aubio, 0.4.1, is out. aubio is a library of functions to perform audio feature extractions such as: - note onset detection - pitch detection - beat tracking - MFCC computation - spectral descriptors This version is mostly focusing on media file input and output. Here is a quick overview of the changes. The most interesting feature in this release concerns aubiocut. Thanks to the sponsoring of Mark Suppes, the python script to slice sound steams was extended to be sample accurate, cut overlapping segments, and work on multiple channels. New source and sink objects have been added to let aubio read and write WAV files, even when built with no external libraries. This should simplify the use of aubio on platforms such as Android or Windows. Existing sources and sinks have been extended to read and write from and to multiple channels. This makes python-aubio one of the fastest and most versatile Python module to read and write media files. This release also comes with a stack of bug fixes and code clean-ups. Note: this version is API and ABI compatible with 0.4.0. Since it only adds new features to the existing interface, your existing source and binary code will keep working without any modifications. To find out more about aubio and this release: Project homepage: http://aubio.org/ Post announcing aubio 0.4.1: http://aubio.org/news/20140312-1953_aubio_0.4.1 ChangeLog for aubio 0.4.1: http://aubio.org/pub/aubio-0.4.1.changelog Source tarball, signature and digests: http://aubio.org/pub/aubio-0.4.1.tar.bz2 http://aubio.org/pub/aubio-0.4.1.tar.bz2.asc http://aubio.org/pub/aubio-0.4.1.tar.bz2.md5 http://aubio.org/pub/aubio-0.4.1.tar.bz2.sha1 API Documentation: http://aubio.org/doc/latest/ Happy hacking!
