[announce] [pd-fileutils] released, a command-line tool for managing pd files
by s p 05 Mar '13

05 Mar '13

Hi all! I am pleased to announce that I just released the first working version of pd-fileutils (https://github.com/sebpiq/pd-fileutils) which is a node.js package and a command-line tool for fiddling with pd files. Right now, the command-line tool only allows you to render .pd files to SVG, but expect more functionalities in the future (I am open to suggestions). If you know JavaScript and node.js, you can also use the API for scripting operations with your pd files. Right now, it can only parse .pd files to a standard JavaScript object, which you can then manipulate easily with JavaScript. This library is a by-product of the WebPd project ( https://github.com/sebpiq/WebPd), which aims at running Pure Data patches on the browser. It is also a proposal for an alternative file format for Pure Data, based on JSON. There was a discussion about that on pd-dev : http://lists.puredata.info/pipermail/pd-dev/2012-06/018436.html and I would like to start it again ;) Cheers! Sébastien Piquemal PS : there will definitely be bugs, so don't "hesitate" to report them :)

[PD-announce] Concordia Laptop Orchestra and Acoustic Friends - Liveware! This Thursday (March 7th @ 7P)

Concordia Laptop Orchestra and Acoustic Friends - Liveware! Thursday, March 7th, 2013 @ 19:00 Concordia Music Department John Molson School of Business 1450 Guy St., 8th floor, room 245 Also webcast (see below) Free admission! This Thursday at 7 PM, come join Concordia Laptop Orchestra (CLOrk) for a casual evening concert with some excellent pieces by Michaël Bresse, Joe Browne, Michael Palumbo, and Ryan White, plus a closing CLOrk beat-jam. Each piece utilizes the laptop orchestra medium in a very different manner: In Michaël Bresses’s piece, the laptop orchestra will explore texture and space under his conduction. In Joe Browne’s piece, bass trombonist Felix Del Tredici will interact as soloist with the laptop orchestra and with snippets of his own live sounds processed and spatialized in 8 channels. In Michael Palumbo’s piece only one computer will play a sound, but 20 people will shape and transform it. Ryan White’s meditative piece with Christian Brun del Re (drums) will utilize the laptop orchestra as a glitch percussion ensemble. CLOrk’s beat jam is like… Mouse on Mars meets Autechre meets Tam Tams Montreal. The show will be webcast (audio) at http://mixlr.com/eldad-tsabary or http://pdradio.listen2myradio.com/ (plan B) Check CLOrk out: CLOrk’s sounds: https://soundcloud.com/clork-1/ CLOrk’s videos: http://tinyurl.com/cl47htd Facebook event:http://www.facebook.com/events/148884571939776/ Current CLOrk members: Lyndsie Alguire, Charles Bale, Philippe Blanchette, Michaël Bresse, Joseph Browne, Stephanie Colbourn, Pasquale De Luca, Alexis Dionne, Byron Edelmann, Frankie Fiore, David Fiorentino, Christopher Gorman, Regynald Guzman, Jared Jukes, Reginald Kachanoski, Megan Keenan, Marco Antonio Liy Menor, Marguerite Luu, Ryan McNabb, Keith Odell, Michael Palumbo, Pierre Perry Pilloy, Edan Scime Stokell, Evan Stepanian, Michael Sullivan, Ryan White, Simon White, Eldad Tsabary (director) _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] help with pd error
by Hans-Christoph Steiner 05 Mar '13

It looks like the Gem model loading error message is somehow being executed by Pd. That's an odd one. Can you narrow it down? Can you provide a working example so that I can reproduce this on my machine? .hc On 03/04/2013 11:16 AM, Patrick Pagano wrote: > This pd extended 0.43-4 > Ubuntu 64 bit > When i am clicking on Hradio buttons, this TCL error appears > > } {} 1 (Tcl)\ MISSING\ CLOSE-BRACE\ '\}':\ missing\ close-brace\n\ \ \ \ > while\ executing\n\"\00\}\ 1\ \{_glmFindMaterial():\ \ can't\ find\ material\ > \"initialShadingGroup\".::pdwindow::logpost\ \{\}\ 4\ \{loaded\ image\ > '/home/shree/Desktop/vj-live2\ (1)/images/...\"\n\ \ \ \ (\"uplevel\"\ body\ > line\ 4)\n\ \ \ \ invoked\ from\ within\n\"uplevel\ #0\ \$cmds_from_pd\" > > then the GUI does not update.

Re: [PD] pd-l2ork feedback
by Ivica Ico Bukvic 04 Mar '13

04 Mar '13

OK, I checked your patch and now I know why this is happening. Allow me to explain: short (tl;dr) version: once mknob is accelerated (which should be only a couple of lines of code inside it) this won't be a problem any more For me it takes approx 3 seconds every time I move the gop window and this solely because mknob is not accelerated (this is on an HP dm1z AMD APU notebook/netbook). long version: What's happening is that pd/extended completely redraws gop object every time it is moved. What it does not do, is account for its location (front vs. back) in respect to other objects when doing this. So, for instance if you move a gop that is behind another object, once it has been moved, it will appear in front of it which is wrong since that is not an accurate reflection where in the gl_list it is located. Hence, next time your entire canvas redraws (which happens inside pd/extended at various points), suddenly gop will be again behind the other object. Confusing, no? Pd-l2ork in an attempt to keep gl_list consistent always ensures that objects remain visually stacked on top of each other in the gl_list order no matter what operation you do. In this case, because we have one of the few remaining gui objects that do not support accelerated displacement (by accelerated displacement I mean tagging such object's components in tcl tk and then moving all objects tagged with the word "selected" together via a single command rather than redrawing everything), pd-l2ork falls back to the old pd/extended way of doing things, just like pd/extended do. It does this with one notable exception and that is to ensure that the redrawn object remains stacked where it should be (in terms of front/back) it also redraws the canvas after such a drag because old way of redrawing does not account properly for the visual order that pd-l2ork requires. Since your patch has literally a ton of objects pertaining to ssssad presets, this takes a while, and hence the slowness. If you, however, put any iemgui object instead of mknob inside that gop, the thing will be not only fast, but also much faster than regular pd/extended. So, what I can do for the next release is add support for accelerated displacement of mknob and you'll be set. Another related issue is the redundant use of hundreds of ssssad abstractions. Pd-l2ork has system-wide preset_hub/preset_node externals system which is easy to use, supports use in conjunction with multiple instances of the same abstraction (each is treated separately and distinctly) as well as many other cool features. Think of it as pd's counterpart to Max's pattr_storage. Their implementation is currently possible only in pd-l2ork since it ensures that all objects remain in the same place in the gl_list (let's call this gl_list consistency) which is something that regular pd/extended don't do (as described above). So, long story short, if you use preset_node and preset_hub you will need only one of those to replace all of your ssssad abstractions. Pretty nifty? ;-) And that in near-term will make your canvas redrawing much faster and consequently a non-issue.

learning ambisonics - cartesian to polar patch?
by João Pais 04 Mar '13

04 Mar '13

Hello, I wanted to learn how to use ambisonics to use them in my patches. So far my attempts have failed, as I didn't find any documentation that gave me a good overview on the subjetc. Mainly, what I needed was a patch that allowed me to send in cartesian (x,y) coordinates of a room, and spacialize the sound in an ambisonic format. Does anyone have such a model that I could follow? Best, jmmmp

send .pd_linux files from maxlib?
by João Pais 04 Mar '13

04 Mar '13

Hi, the latest version of pd-ext for debian has the externals of maxlib compiled in the wrong format. Can anyone out there send me a zip file with the .pd_linux files from the extra/maxlib folder? I'm using debian squeeze 32b. Please send directly to my mail, not to the list. Thanks, jmmmp
