-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear List, coincidently there is a great artists run space in Weimar organizing an stipend for artists to work and live in Weimar happening parallel to the Bauhaus Summer School and the 4th Pure Data Convention. For the conditions and details read the original announcement: Friends of the Galerie Eigenheim, in 2011, the Galerie Eigenheim from Weimar awards again a scholarship for young artists. Because of space infrastructural changes the constitutions slightly modified compared to previous years. In the last 3 years the scholarship was coupled to a six-month residency in the premises of the gallery, it will be advertised as a one-month Artist in Residence program this year. Related to meaning of the name origin of the gallery, an artist or a group of artists can use all rooms of the Gallery from mid of July till mid of august for presentation, work and society. Together with our 3M program (muse, mentor, marketing), we are strongly supporting the scholarship holder during his stay and promote him/her work the best way we can. We hereby call for national and international artists of all directions to supply until May 31, 2011 for the scholarship at Galerie Eigenheim in 2011. We look forward to varied submissions and unusual concepts. At the scholarship no monetary funding is coupled. Housing and accommodation will be made available in Weimar. A regular presence during the fellowship is desired. The legal procedures are excluded … Submissions or questions per mail to: konstantin.bayer(a)galerie-eigenheim.de or by post to: Galerie Eigenheim Karl-Liebknecht-Str. 10 99423 Weimar Webpage: http://www.galerie-eigenheim.de/?page_id=1438 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAk3ZNn0ACgkQ3EB7kzgMM6ILGQCeKZgZht7khdcSZqM+RIle3giu bIkAnRLTW+la4uc8WDszKZJUrZoo3hnI =46r/ -----END PGP SIGNATURE-----

routeOSC: how to distinguish messages addressed to a node from messages addressed to any descendant
by Matteo Sisti Sette 22 May '11

22 May '11

Hi, Suppose that in an OSC tree I have a node called "foo" (child of the / root node) which has a few child nodes. So I place a [routeOSC /foo] object to get all messages that are addressed to /foo or to its child nodes. This will catch all of the following messages: /foo 123 /foo/bar 123 /foo/etc 123 Now, how can I discriminate messages like the first one from messages like the others? I.e., messages directed to the /foo node and not to any descendant? I don't think I can accomplish this with [routeOSC], or can I? Indeed I think that [routeOSC /] should match any message that doesn't start with an address, or alternatively, matching messages output by the first outlet of a [routeOSC /something] should start with "/ " if the pattern address matches the whole input address. However I understand this would break existing patches. Or is there another way to discriminate the above? Thanks m.

DorkbotPDX Synthesis Workshop, May 29th, Portland, OR, US
by Jason Plumb 21 May '11

21 May '11

DorkbotPDX is proud to announce a unique *free* workshop geared at teaching sound synthesis fundamentals as explored and demonstrated through Pure Data (PD). Sunday, May 29th, 2011 - 1-5pm PST @ Pacific Northwest College of Art (PNCA), room 205 1241 Northwest Johnson Street Portland, OR 97209-3023 Fascinated by orgies of towering analog synthesizers from the 60s? Mesmerized by how computers can generate sound that offends and elates? In this casual yet intense session, we will cover the basics of audio signal theory while exploring the common techniques and tricks used by sound designers and synth builders. Participants should bring: [*] A mac/linux/win laptop with a functioning Pure data install. (This is free and open-source software!) Download either 'Vanilla' or 'Pd-extended' here: http://puredata.info/community/projects/software [*] A basic/rudimentary knowledge of Pd. (Not 100% required - but at least a very basic understanding of what Pd is will help) [*] Headphones [*] An eagerness to learn, develop, and share! The synthesis workshop is FREE and OPEN TO THE PUBLIC Seating is limited to 30 (first-come, first serve) http://dorkbotpdx.org/wiki/synthesis_workshop_in_pd

Extended View Toolkit
by news＠petervenus.de 21 May '11

21 May '11

Hello All! I want to announce the official release of the Extended View Toolkit. http://puredata.info/Members/Weitsicht/extended-view-toolkit/ The Extended View Toolkit is a set of abstractions developed for the art installation "Extended View streamed". It is intended to be an easy solution to experiment and realise panoramic video and complex multiscreen projection environments to createimmersive media experiences. It features a set of abstractions that are able to combine multiple related image-sources (like video input, video playback) into aconsistent panoramic image. The source-material, e.g. the camera to display has to be aligned horicontally, since image-combination is based on simple, openGL basededge-blending and not algorithmic pix by pixel comparison. Furthermore it features abstractions to create multi-screen, multi-projector environments to enable correct representation of (not only)panoramic material. The projection abstractions can be combined to form big screens out of multiple projectors with softedge betweenoverlapping borders of single projectors and contain a vertex model that can be adjusted in 4, respectively 9 points, so that projections onchallenging geometric surfaces is possible. Additionally, all abstractions are controllable via OSC-styled send/receive-messages, which simplifies OSC-based external control. Also, since streaming video was part of the project, a gstreamer based streaming solution was developed by Peter Innerhofer to distribute panoramic/multistream video over network. It can be found here: [https://github.com/peonic/streaming] Libraries needed: mrpeachBuilt with pd 42.6 and GEM 92.3 Credits: Shader Programming/openGL: Cyrille Henry GEM: Marian Weger Prototyping/GEM: Peter Venus Streaming: Peter Innerhofer Initiation/Supervision: Winfried Ritsch A short demo-clip can be found here: [http://vimeo.com/20311051] The project was made possible through support from IEM-Institute for Electronic Music and Acoustics (iem.at) and CO-ME-DI-A. The CO-ME-DI-A project is supported by the Education, Audiovisual & Culture Executive Agency (EACEA) of the European Comission forthe period 2007 - 2010 ([http://www.comedia.eu.org/]). Your feedback is welcome! Peter

XY abstraction
by Pedro Lopes 20 May '11

20 May '11

I'm trying to find an already-made XY abstraction, and it seems that this could be the one: - http://puredata.info/Members/bbogart/XY-Controller/view Although I cannot use it, what file type is this? Best, Pedro p.s.: I did some digging into file type and I got: pedro@io:~/Downloads$ file file file: gzip compressed data, was "xy-controller.tar", from FAT filesystem (MS-DOS, OS/2, NT), last modified: Mon Jun 2 23:29:18 2003 But even so, it doesn't uncompress here in my Linux. -- Pedro Lopes (HCI Researcher / MSc) contact: pedro.lopes(a)ist.utl.pt website: http://web.ist.utl.pt/Pedro.Lopes / http://pedrolopesresearch.wordpress.com/ | http://twitter.com/plopesresearch

Ubuntu Linux to Mac OSX Question
by Brian Shepard 19 May '11

19 May '11

Greetings, I have a student using Pd-extended on Ubuntu Linux, and I am using PD-extended in Mac OSX. When he sends me a file created on his computer, I can't open it, and get something like the following in the console: error: #N: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object error: #X: no such object When I send him patches, he can open them just fine. If he sends me a screen grab of his patch, I can build it and it works just fine. The problem only happens when I try to open the actual Pd file he sent. I've also tried opening them with a text editor, and everything looks fine. If I then copy/paste the text into a new text file and save it with the .pd suffix, though, it still won't open. Is there some issue regarding transferring between these two systems? Thanks for any help or advice. -- Brian
