thirty-fifth meeting of the PureData users group of Montréal
by Mathieu Bouchard 19 May '10

19 May '10

the thirty-fifth meeting of the PureData users group of Montréal will take place at Vidéographe Production, 4550, Garnier st (corner of Mont-Royal ave) on Saturday the 22nd of May 2010, from 13:00 to 17:00. ---------- Forwarded message ---------- Date: Wed, 19 May 2010 08:34:16 -0400 (EDT) From: Mathieu Bouchard <matju(a)artengine.ca> To: pdmtl(a)artengine.ca Subject: pdmtl#35 la trente-cinquième rencontre du club d'utilisateurs de PureData de Montréal aura lieu à Vidéographe Production, 4550, rue Garnier (coin Mont-Royal) le samedi 22 mai 2010, de 13h00 à 17h00. au programme : 1. la patch du projet Aether9 presentée par Christiaan CRUZ et Audrey SAMSON Aether9 is developing a mobility contingent for its performances during a residency at Agence TOPO in Montréal. The aether9 collective has developed its own tool to stream remote performances from anywhere on the globe, which are concatenated and manifested on a web page (in combination with a live performance in front of an audience). This ability to stream audio/visual remotely has thus far depended on Max/MSP. During the residence two aether9 members have been writing and learning in Pure Data to create a PD patch that essentially captures webcam stream, manipulates the image and uploads it to a server. We propose to present our fumbling, our successes and frustrations with making this patch as well as how the project aether9 works. * project website: aether9.org * interface: 1904.cc 2. Gem for data visualization by Peter LEE I will present preliminary work that uses GEM particle systems for data visualization in two projects, one a (possibly) scientific application, and the other for a theater performance. The first feeds data from a genetic study into GEM to visualize multiple variables associating at once. The second takes data generated live from biofeedback sensors to visualize physiologic signals of emotion. Both projects make use of the same interface for patching data to visualization parameters. The challenge is to find the mappings and scaling factors that enhance the viewer’s ability to detect differences in the data. I shall be interested in hearing ideas from the community on how to improve real-time rendering of particle systems to create images with greater nuance and expressivity. 3. Démonstration à choisir par Mathieu BOUCHARD Je vais donner une liste de mes nouvelles patchs de son, de vidéo, etc., et l'auditoire choisira parmi ces suggestions. J'improviserai alors deux courtes présentations. * prototype de jeu de Q*Bert. * prototype de jeu de Tic Tac Toe. * déformation temporelle des pixels sur un flux vidéo. * synthèse de cloches et de cordes sans oscillateur. * synthèse fait d'un filtre à pôle complexe et d'un gros rien. 4. Traduction (discussion de groupe) Ce sera une discussion informelle pour savoir qui est intéressé à participer à des efforts de traduction de la documentation de PureData. Nous parlerons de différentes sources de documentation et de diverses approches de traduction. Cette discussion a été proposée par Thomas-O. FREDERICKS, lequel sera absent ce samedi. Nous poursuivrons cette discussion lors d'une rencontre ultérieure. 5. temps libre (jusqu'à 17h00) _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard, Montréal, Québec. téléphone: +1.514.383.3801

Fwd: Places free for RAFAEL TORAL SPACE PROGRAM WORKSHOP
by João Pais 19 May '10

19 May '10

WORKSHOP 27-30 MAY 2010 RAFAEL TORAL SPACE PROGRAM WORKSHOP: Rethinking Electronic Music Rafael Toral calls his playing style “post-free jazz electronic music”, once described as “a brand of electronic music far more visceral and emotive than that of his cerebral peers”. Toral’s Space Program delivers music that is full of clarity, articulating silence and sound in a thoughtful, yet physical way. A long time collaborator of Sei Miguel, he has performed throughout Europe, Canada, USA, South Korea, Japan, New Zealand and Australia, released 13 albums and produced the first Anthology of Portuguese Electronic Music. He is a member of MIMEO orchestra. http://rafaeltoral.net Electronic Music development has historically been mostly oriented to the sound source (technology) and the object (finished work). Unlike in jazz, the individual is rarely the focal point. More concerned with the musician than with the instrument, the Space Program is Rafael Toral’s long-term research into human performance possibilities in Electronic Music, a fundamental reevaluation of its conception, performance and experience. The Space Program Workshop shares some concepts, focusing on how we make performance decisions. Aimed at musicians using hacked, bent, or custom electronic instruments, it raises fundamental questions about what can we do with them. The Workshop provides participants with conceptual tools for structuring musical discourse, with emphasis on phrasing from Space Program’s viewpoint. The workshop has the duration of 4 days and covers topics like: 1. Matter: Instrumental choices and interface optimization. 2. Discourse: elaborating a syntax and articulating silence. 3. Composition: listening modes and macro-form decisions. 4. Performance: the body on stage and functions in a group. Participants are enabled to perform collectively in the end. What is required : - The Space Program Workshop has to do with electronic instrument control. Your instrument absolutely needs to be able to instantly start and stop making sound. - It is aimed at non-conventional electronic instruments that require a physical interaction. No keyboards. No classic instruments. No computers (except with gestural controllers). - Previous hacking workshops and basic electronics knowledge are preferred. - It’s about simplicity. Be prepared to focus and simplify your sound. - A small mixer if you have several sources (your output should be one channel). - Headphones (and your own monitor circuit, mixer, etc., if necessary) What is offered : - Focus on your instrument technique and choice of sounds to perform. - Structure your sounds, establishing a personal lexicon. - Exercise an articulated way of listening and dealing with silence and “space”. - In short, to develop a physical, organic, elemental approach to electronic music. Schedule for Workshop: May 2010 27: 15:00 – 19:30 (with coffee break) 28: 10:00 – 13:00 // lunch break // 14:30 – 18:00 29: 10:00 – 13:00 // lunch break // 14:30 – 18:00 30: 10:00 – 13:00 // lunch break // 14:30 – approx: 17:00 // // move to ausland – sound check /performance at ausland LychenerStr. 60 10437 Berlin Doors open at 9pm Performance begins at 10pm Workshop Location: @ NK Elsenstr. 52 2HH 2Etage 12059 Berlin Participation is limited to 6 participants.

gendy~ PD + Max/MSP object and libgendy 0.6.0 released
by Spencer Russell 17 May '10

17 May '10

Hi Pd-ers, I've been working off and on for a bit on a C++ library to implement a variant of Dynamic Stochastic Synthesis, a technique developed by Iannis Xenakis. (For a great history and more details check out Sergio Luque's thesis [1]. The library is still pretty rough around the edges and more or less completely undocumented, but the PD object that uses it should be pretty functional. Included with the code is a helpfile as well as a gui that should make it pretty easy to jump right in. The basic idea of DSS is to describe a waveform with a set of "breakpoints" and interpolate between them to generate the actual audio signal. The set of breakpoints forms a single cycle of a waveform, and each time one cycle gets played, the breakpoints each move for the next cycle. So each breakpoint traverses a two-dimensional random walk. One improvement I've made to some traditional DSS implementations is the use of cubic spline interpolation instead of linear, which improves the aliasing considerably. It's not a truly bandlimited signal, but is differentiable. "improves" is obviously subjective, and linear interpolation is also available by sending a "linear" message to the object. The other modification is the introduction of selectable center waveforms that the breakpoints will gravitate towards. Right now I only have flat, square, and sine implemented, but I'm planning on including basic triangle and sawtooth as well. The "h_pull" and "v_pull" controls effect how much the breakpoints are pulled towards the center waveform. The external requires Thomas Grill's Flext library. Once you have it installed simply run FLEXTDIR/build.sh pd gcc >From the base gendy directory (Where FLEXTDIR is the location of your flext install) and you should have a shiny new binary in the pd-linux directory. The arguments to build.sh will vary depending on your system, as will the directory containing the binaries. Please report any bugs to http://code.airwav.es/projects/gendy/issues/new Downloads: Source Tarball - http://code.airwav.es/attachments/download/4/gendy-0.6.0.tar.gz x86_64 PD Binary - http://code.airwav.es/attachments/download/3/gendy~.pd_linux You can also get the code with git clone http://git.airwav.es/gendy.git gendy [1] http://www.sergioluque.com/texts/luque_stochastic.pdf

Blocked Signal/Score Processing with Pd / + physigs
by Frank Barknecht 17 May '10

17 May '10

Hi, at LAC2010 I presented a paper on "Blocked Signal/Score Processing" or BSP with Pd. It explores ways to use Pd's signal operators for more control oriented applications to allow block-processing of control stream data that are normally dealt with by message operators and shows some examples including a physical modelling system for Pd vanilla that is similar to MSD/PMPD - and that it damn fast for a vanilla solution. Paper, slides and a video of my presentation are available at the Linux Audio Conference 2010 site: Paper: http://lac.linuxaudio.org/2010/papers/24.pdf Slides: http://lac.linuxaudio.org/2010/download/lac2010_bsp_in_pd.tgz Presentation: http://lac.linuxaudio.org/2010/recordings/day3_1045_Applications_of_Blocked… The code for the [physigs] abstraction shown there is at github: http://github.com/footils/physigs Comments welcome. Ciao -- Frank Barknecht

problem with ipad
by Fernando Rabello 15 May '10

15 May '10

Hi, I don't really know much about Pd. But I followed the guide of the app Pianist Pro in my iPad, and it sugested Pd for converting OSC to MIDI, so I can use Pianist Pro in GarageBand. It told me to download a .pd file, and so I did. But when I click it, the program runs and in the end it tells: error: <!DOCTYPE: no such object error: charset=Windows-1252">: no such object I assume that this is the problem, because if I click again on the .pd file, the same message appears. Can someone help? Thanks!

Cet événement public est une discussion ouverte sur pdpédia et la documentation francophone du logiciel Pure Data en général. L'idée de cette discussion est de créer un lien entre les avis des experts et développeurs, et la réalité des jeunes utilisateurs de pd, pour que tous s'approprient la documentation de pure data. Ce logiciel est libre, il appartient à chacun de nous de le faire avancer en fonction de nos besoins. Des développeurs de la communauté francophone sont en discussion sur la mise en place d'outils de documentation de pd depuis longtemps, plusieurs pistes ont été proposées mais aucune décision n'est prise, les avis divergent, le sujet est complexe. Jérôme Abel et Jean-Marie Boyer vous proposent dans un premier temps de vous rapporter plusieurs avis contradictoires sur la question, de vous transmettre un maximum d'informations tirées des listes de discussion dédiées à Pure Data. À l'issue de cette présentation, nous vous proposons d'apporter vos propres avis à travers des petits jeux de prise de parole sur une problématique à la fois, liée à la forme et aux contenus que pourrait appréhender cette documentation. Nous rapporterons cette session de discussion à l'ensemble de la communauté pure data francophone.

High Spheres - Open air multi-channel participative concert @ Re-New Festival, Copenhagen, Denmark
by Marco Donnarumma 14 May '10

14 May '10

Dear all, On 18th May at 19.30 I'll be performing 'High Spheres' a participative multi-channel concert for found objects and reactive generative music for the opening of Re-New Digital Arts Festival, Huset i Magstræde*, *Copenhagen, Denmark. I actually provide only the software and what the music will be like only depends on the people participating. The action takes place open air. No musical instruments are provided, but stones and leaves. Audience can use 6 microphones/loudspeakers to amplify any kind of sound they wish to produce. The whole sonic matter is managed by a Pd-based software, which interacts with the audience processing in real-time the sounds they produce, analyzing the input signals and generating new sounds out of the collected data. An endless sonic data flow which, once started, will live and grow beyond the time-space of the action. If you're in the city you're very welcome to join our self-organized orchestra... Further info: http://marcodonnarumma.com/works/high-spheres/ the audio excerpt there is quite old and was made in AudioMulch, the Pd patch I developed now sounds much more interesting, hope to record the session and post it here. http://re-new.org/program/ @ Thomas Grrr.. I saw you'll be there too, it will be a pleasure to meet you! -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher - Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net
