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)

Rivendell v2.5.5

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the availability of Rivendell v2.5.5. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. From the NEWS file: *** snip snip *** If upgrading from a v1.x version of Rivendell, be sure to read the 'UPGRADING' file before proceeding for important information. Changes: RLM API Extension. Added new fields to the 'rlm_pad' struct to allow plug-ins to determine actual and predicted start times for events. RDMonitor Enhancements. Extended RDMonitor to allow proper positioning on multi-head displays. LiveWire Switcher Driver Changes. The switcher drivers for LiveWire have been refactored into three separate drivers: LWRP Audio - Allows switching of audio routes on LiveWire devices. LWRP GPIO - Allows monitoring and control of LiveWire GPIO devices via LWRP (both virtual and direct). Multicast GPIO - Allows monitoring and control of LiveWire console GPIO without the need for a virtual LWRP device. See 'SWITCHERS.txt' for details. RDSelect Enhancements. Added support for specifying CAE and RDXport service assignments via RDSelect configurations. Multiple bug fixes. See the ChangeLog for details. Database Update: This version of Rivendell uses database schema version 220, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. *** snip snip *** Further information, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

NIME 2014 London - Call for Proposals

by Marco Donnarumma

Hi all, The New Interfaces for Musical Expression (NIME) conference comes to London in 2014! We would love to receive contributions from LAU community, and given the LAC conference is around the same time, this make the chance for a great summer of weird sounds! Please see below the call for proposal and circulate as appropriate. The Performance and Installation call for NIME 2014 is out now and the deadline for submissions is in LESS THAN TWO WEEKS' TIME: 1st December, with no late submissions accepted. We would therefore like to encourage everyone to get thinking about what they might like to present in this category! For NIME 2014, we will be hosting performances and gigs in a variety of venues around Central London. We plan to make some of these events open to the public and are looking for really high quality performances, from proven performers and makers. We hope to include a diverse range of performances, and so are keen to receive proposals which are out of the ordinary. For example, work which focusses on the body in performance, such as the human voice, the body in dance, or indeed music which makes audiences dance. We also encourage works which challenge the conventions of NIME, such as notions of liveness, or the role of notation, language or code in performance. Historical perspectives on music performance technology are also welcomed, for example work which combines computation with textiles, augments traditional instruments, or draws on complementarity with visual forms. With the increasing influence of the maker movement, we also welcome proposals which include ad-hoc, DIY and open source instruments. If you have something you'd like to show in a less polished way, you can simply tell us you'd like to show a 'performance demo' and these will be most likely programmed in smaller venues closer to the conference site. The call can be viewed at the link below. http://www.nime2014.org/call-for-participation/ If you have any questions, please contact the artistic committee here: nime2014music(a)goldsmithsdigital.com Hope to see some of you there! best wishes, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director. Embodied Audio-Visual Interaction Research Team.

nxjsm 0.1

by Pawel

Hello, I wanna share with community my very simple Jack session manager. It console app and is intended to use from scripts ( even if this is rc.local ;-) - or it could be linked to some icon/activator on desktop ;-) It use libconfig for store settings and CDK ( ncurses ) for display while it "watching". In save mode it works almost like jack_session_notify ( this part of code was partially borrowed, but was fixed, optimized and adapted - e.g. it doesn't store duplicate connections. take care of trailing slash in session directory, use libconfig etc. ). Load mode was written from scratch. It start stored apps, restore it's connections and then it works like watchdog. It should be ( and it is at least for me ;-) useful for live performances. There is also simple script which merge this two functionality, and it can also start start jack and wineserver (in persistent mode), export WINE_RT variables etc. Check this url: http://sourceforge.net/projects/nxjsm/ I use this already in my band, so let this publicity of our song will be my "salary" ;-) https://www.youtube.com/watch?v=gVs2IN9IrRI Best Regards Pawel
