PHASEX-0.12.0-beta3

by William Weston

Announcing the new public beta release of phasex! All phasex users are encouraged to upgrade. Since the days of 0.11.1, all known bugs and many annoying quirks have been worked out, making PHASEX-0.12.0-beta3 is the most stable, best sounding, and most studio friendly release yet: * Fixed all currently known crash issues and build issues. Code has been updated for newer versions of gcc, gtk, and glibc. Realtime threading issues have been fine-tined, using realtime locks where appropriate. The build system has been fixed up for newer distributions and includes default optimizations for the entire x86 family (run './configure --enable-arch=foo', where foo is an architecture supported by your version of gcc). * Sound quality has been greatly refined by reshaping envelope curves (eliminating pops and clicks), adding hermite interpolation to the chorus (removing fuzziness from chorus), adding fine tuning to oscillator frequencies and FM amounts, adding sampled oscillators (currently with Juno-106 and vocal samples), fixing portamento and key triggering logic, and more. * The JACK code has been reworked to allow multiple instances with persistent instance numbers and resilience to JACK crashes and restarts. * The GUI has been refined slightly, with a new color scheme, patch folders in the file dialog shortcuts list, and a couple slight optimizations to the knob code. * There's more. See http://sysex.net/phasex/beta for details if you're that curious. Since 0.12.0-beta2, fixes have been implented for GTK >= 2.16 (fixing Fedora 11 builds), the max polyphony has been turned into a runtime configurable setting, and the build system and default architecture specific optimizations have been fixed up some more. Source tarball and arch specific Fedora 11 RPMS are now available for download: http://sysex.net/phasex/beta/phasex-0.12.0beta3.tar.gz http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.src.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i386.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i586.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i686.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.athlon.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.amd64.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.x86_64.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.ia32e.rpm Build reports and bug reports, and package build files for all distributions are highly welcome. This is the final beta for 0.12.0. Any build and crash issues reported in the next two weeks will be fixed for the 0.12.0 stable release. Please direct any feedback to weston(a)sysex.net. The latest version of phasex can always be found at: http://sysex.net/phasex For those of you who use git: git clone http://sysex.net/git/phasex.git Thank you all for your support, feedback, and contributions over the years, helping to make PHASEX what it is today.

The fourth edition of make art – What The Fork?! distributed and open practices in FLOSS art - will take place in Poitiers (FR), from the 7th to the 13th of December 2009. make art offers performances, presentations, workshops and an exhibition, focused on the encounter between digital art and free software. We're currently seeking new, innovative FLOSS works and projects: music and audiovisual performances, presentations, software demos, and installations. This year make art focuses on distributed and open practices in FLOSS art. 'What the fork?!' is about decentralisation. Forking is the new black. Forking, copying the source code of a project and continuing work on the copy instead of the original, used to have a bad reputation. It would split a project and its developer community in pieces, leading to different, often incompatible, projects. Wasted effort, rivalry and developer fights were all associated concepts. This is history. Forking a project with the intention to compete with it is another story, but the freedom to fork enables quick implementation of features and customization, bypassing acquiring committer status, bugfix or feature request protocol, working in a distributed way, together with others but not necessarily towards one goal, working from one source, cross-fertilising, inspiring, copying, patching, improving, experimenting, changing direction, and merging. This practice is boosted by decentralised software development tools, such as Darcs, Mercurial and Git. It's not about quick hacks, but about creating room to experiment, letting go of the one working copy and creating a multiplicity of ideas. Extended deadline : 22nd of July 2009.

La quatrième édition de make art – "What The Fork?!" pratiques distribuées et ouvertes en art FLOSS – se déroule à Poitiers (FR), du 7 au 13 décembre 2009. make art propose des performances, des présentations, des ateliers et une exposition, centrés sur la rencontre entre l'art numérique et le logiciel libre. Nous recherchons actuellement des projets récents, innovants, basés sur des logiciels libres et open source : performances musicales et audiovisuelles, présentations, démonstrations de logiciels et installations. Cette année make art sera centré sur les pratiques distribuées et ouvertes en art FLOSS. Dans 'What the fork?!' il est question de décentralisation. Le fork c'est le bien. La pratique du Fork, qui consiste à copier le code source d'un projet puis de continuer à travailler sur une copie plutôt que l'original, a ouvent eu mauvaise réputation. Car cela engendrerait une scission au sein du projet et de l'équipe de développeurs, et conduirait à des projets différents et souvent incompatibles. Efforts gaspillés, rivalités et querelles de développeurs, autant de concepts qui y sont associés. Tout ça c'est de l'histoire ancienne et créer le fork d'un projet dans l'intention de rivaliser est encore une autre histoire. La liberté de faire un fork permet la mise en oeuvre rapide de nouvelles fonctionnalités et de personnalisations, en contournant la nécessité d'acquérir le statut de celui qui dépose et valide (le "committer"), en contournant les protocoles de corrections de bug ou de demandes de nouvelles fonctionnalités, en travaillant de manière distribuée, ensemble avec d'autres sans être obligé de suivre le même et unique objectif, tout en travaillant depuis la même source, mais en opérant par fertilisation croisée, en insufflant, en copiant, en patchant, en améliorant, en expérimentant, en changeant de direction et en fusionnant. Cette pratique est largement boostée par les outils décentralisés de développement de logiciel tels que Darcs, Mercurial ou Git. Il ne s'agit pas de hacks faits à la va-vite, mais la création d'une chambre d'expérimentation, qui laisse de côté la copie unique du travail et qui démultiplie les idées. Date limite prolongée: 22 juillet 2009. [1] FLOSS : Free/Libre/Open Source Software Pour plus d'informations : http://makeart.goto10.org/call/index.fr.html -- :*
