import-disabled list-abs
by Luka Princic // Nova deViator 14 Feb '11

hi, i'm working on an abstraction that contains an object from a library for which i need to create [import nusmuk] in order to use ([granulator]). when i create a new instance of that abstraction, pd console reports import-disabled list-abs ... couldn't create could someone explain what this error means? is it deprecated to use [import] and i should rather use syntax like [nusmuk/granulator] ? l. -- sujet est machinique!

Re: [PD] sssad and different $0 after shutdown
by Marco Donnarumma 14 Feb '11

Thanks Andras, yes I know I could, I was curious to understand if a solution including $0 could've been possible. That's probably the way although I should modify all the abstraction created so far one by one or editing with nano, but that's not straight-forward either. > Maybe i'm overseeing something, but cannot you create named instances like > [my.chorus cho1] and use $1 instead of $0? > > Andras > -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher Ongoing MSc by Research, University of Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net

[GEM] pix_film mjpeg crash
by Luka Princic // Nova deViator 14 Feb '11

14 Feb '11

hi, been reading some previous discussions, and it seems like the best codec for pix_film is mjpeg, as in not-cpu-expensive. if i encode my movies with ffmpeg with parameters -an -vcodec mjpeg -sameq pd crashes when trying to open that avi in pix_film. pix_film reports on creation: pix_film:: quicktime support pix_film:: libmpeg3 support pix_film:: libaviplay support there is no error on stderr apart from [pix_film]: opening video-mjpeg.avi with format 1908 [pix_film]: ... [pix_film]: ... [pix_film]: ... socket receive error: Connection reset by peer (104) Segmentation fault if anyone would have an idea how can i make Gem work with mjpeg videos it would be greatly appreciated. l. -- sujet est machinique!

Re: [PD] Need Help Understanding pack
by Matt Barber 14 Feb '11

Hello, Before you go any further in Pd, you should check out the [trigger] object. It's the single most important object in Pd, in my opinion - it will help you get the timing right in these kinds of situations. Trigger forces hot-cold things to happen in the correct order explicitly -- without it you have to rely on the order in which you made the connections, which you can't SEE in the patch. You should use [trigger] instead of the [pipe 0] construction you have as well, the number box should most likely be a message with a zero in it (to hardwire it to zero), and you should probably be sending it to the cold inlet of the [int] (so that it just sets the [int] state rather than passing the zero through once when you set it and then once again on the first bang of the [until]). But again, master the use of [trigger] before you go any further -- multiple lines coming from an object should make you feel uncomfortable until you're sure you're doing it correctly. I hope this helps.

[ngrid]?
by Tyler Leavitt 13 Feb '11

13 Feb '11

Hello all, So I posed a question about calculating triangles made by intersecting lines is a pentagon (thanks for the help Mathieu), and now that it is done I want to easily control the 5 vertices. I remember using [ngrid] at some point, which is [grid] but with multiple vertices... exactly what I need. Googling turned up this: http://puredata.hurleur.com/sujet-1378-designing-surround-sound-mixer which basically says [ngrid] is in the ix library. Well I can't find any mention of ix library anywhere... Does anyone know of this library/[ngrid]? I just installed extended 0.42.5 fresh thinking it would be in there...but nothing. Tyler

On Sun, 13 Feb 2011, Jonathan Wilkes wrote: > Is #4 below a quine? All of them are based on the same principle of a patch taking its own screenshot, and showing it through a [#see] object. The difference is in whether you can see the whole patching distinctly or not, as some are more downscaled than others, and some have missing pieces (that have gone out of the frame), and those missing pieces are sometimes pieces of the patching. But before calling it a quine, you have to ask yourself what's the input, what's the output, how to make the output correspond to the input (especially : in which format), and whether a quine is allowed to use self-reference tools (self-screenshot, self-[textfile], canvas queries) instead of being forced to use other means, such as the usual "Y-Combinator" : main() {char *s="main() {char *s=%c%s%c; printf(s,34,s,34);}"; printf(s,34,s,34);} (this example is in C language) _______________________________________________________________________ | Mathieu Bouchard ---- tél: +1.514.383.3801 ---- Villeray, Montréal, QC

[PD-announce] Call for papers and workshops: Pure Data Convention 2011
by Max 13 Feb '11

13 Feb '11

Paper draft submission: March 28, 2011 Notification of acceptance: May 16, 2011 Final Paper submission: July 11, 2011 The 4th Pure Data Convention will be held August 08-14, 2011, at Liszt School of Music and Bauhaus-Universität in Weimar, Germany. In custom of the previous conventions we invite you to submit your papers related to the Pure Data programming environment in the fields of computer science, artistic creation and scientific research. The papers will be rated according to academic standards such as novelty and relevance in a peer review process. The Pd community is a heterogeneous group of users, developers, authors, artists, musicians, programmers; often in more than one role at a time. Papers from widely divergent perspectives are encouraged. Some possible topics could include: • Libraries and externals extending Pd • Tools built in or for Pd • Education • Spatialisation • Pd on mobile devices • Pd embedded in games and applications • Pd as a framework for audiovisual works Please check the website for the of terms of submission. Templates for the Papers (LaTeX, Open/LibreOffice) will be provided soon on the conventions home page: http://www.uni-weimar.de/medien/wiki/Pure_Data_convention_2011 The conference is held in English, thereby the papers have to be in English. The length of a paper should be 4-8 pages, including an abstract (50-100 words) and up to 5 keywords. Proposals for workshops of all levels, from beginner to special interest, may be directed my email to max.neupert at the domain uni-weimar.de A separate call for music, performances and artworks will follow soon. Please feel free to forward this email to anybody who might be interested! The PureData Convention 2011 organization team.
