a story for Lists
by Hans-Christoph Steiner 10 Aug '09

10 Aug '09

In keeping with the FLOSSmanuals methodology, we need a story to tell when introducing lists. I have the intro done, but now we need a story (i.e. developing an example program). I was thinking that a story involving only lists of numbers would be a good place to start. Anyone have any ideas on that? Here's what's there so far: http://en.flossmanuals.net/bin/view/PureData/Lists .hc ---------------------------------------------------------------------------- http://at.or.at/hans/

test if object-class available
by Enrique Erne 10 Aug '09

10 Aug '09

hi I have a bit an unusual approach to test if dyn~ is available on the platform. In case it is i want to do all my dynamic patching in dyn~. if it isn't available it should do everything with pd-vanilla dynamic patching. My workaround is an abstraction with the name dyn~, this sends a message "dyn~ not available" if it gets loaded. Then I found out that pd-0.42 can do object aliasing (not sure if that is the correct term), which i find a very confusing feature. I was worried that my workaround wouldn't work anymore if the abstraction would "overwrite" the external, but it seems all fine. So the question is are there plans to make abstractions alias object classes ? (i hope not :) ) cheers eni

why is midi out so slow?
by cyrille henry 19 Jul '09

19 Jul '09

hello, i do sometimes use the ctlout object to send midi data out of pd. but latency is very big (about 100ms) i'm using OSS midi on ubuntu linux with vanilia pd. using udpsend to send data to an other application that forward them to the midi out, a loop can be as small as 5ms. (using pdreceive >/dev/midi1 on a terminal by example, see attachment) why are the midi out objects in pd so slow, and is it possible to make them faster? thanks Cyrille #N canvas 97 271 626 429 10; #X obj 160 257 udpsend; #X msg 172 229 connect localhost 2348; #X floatatom 160 162 5 0 0 0 - - -; #X obj 69 230 bng 15 250 50 0 empty empty empty 17 7 0 10 -262144 -1 -1; #X obj 69 258 realtime; #X obj 122 127 b; #X floatatom 69 280 5 0 0 0 - - -; #X msg 160 188 send 176 111 \$1; #X obj 122 78 ctlin; #X floatatom 137 105 5 0 0 0 - - -; #X text 276 39 pdreceive 2348 > /dev/midi1; #X obj 171 208 loadbang; #X text 274 19 open a terminal and start :; #X text 277 60 then click on the connect message box; #X connect 1 0 0 0; #X connect 2 0 7 0; #X connect 2 0 3 0; #X connect 3 0 4 0; #X connect 4 0 6 0; #X connect 5 0 4 1; #X connect 7 0 0 0; #X connect 8 0 5 0; #X connect 8 0 9 0; #X connect 11 0 1 0;

[GEM] ps3eye camera on linux / OSX?
by Jaime Oliver 13 Jul '09

13 Jul '09

Hi, I have changed the subject to [GEM] if perhaps people have missed it... it would be great if anyone else is interested in this because to have a 120fps camera for less than 40$ working in GEM would be amazing... When was the las time you tried this driver? I'm getting one of these cameras at some point this week to try it out. It seems that with that driver you can get a video0 device, but you can only change settings when you load the driver and therefore not through pix_video... I'll let you know if I have any success. I'll also try the macam drivers on os x... cheers, J On Tue, May 12, 2009 at 5:30 AM, Martin Schied <crinimal(a)gmx.net> wrote: > Jaime Oliver schrieb: >> >> So this is the linux driver. if it's not v4l yet could it be grabbed by >> gem? >> >> J >> >> On Tue, May 12, 2009 at 1:28 AM, Jaime Oliver <jaime.oliver2(a)gmail.com> >> wrote: >> >>> >>> Hi all, >>> >>> I have found this great camera: >>> http://shop1.frys.com/product/5421229?site=sr:SEARCH:MAIN_RSLT_PG >>> >>> and multiple threads on drivers at http://nuigroup.com and in the >>> openframeworks forum. >>> >>> the cam can do 120fps@320x240 for 30$ in amazon... >>> >>> I also found an old thread about using pix_freeframe on pd/gem in >>> windows: http://lists.puredata.info/pipermail/pd-list/2008-11/066401.html >>> Has anyone successfully captured this camera in gem on linux or osx? >>> >>> > > tried it on ubuntu 9.04, it works fine with "cheese" and some other > applications, but I had no luck with gem.

Two-dimensional gesture mapping for interactive real-time electronic music instruments
by Thomas Grill 11 Jul '09

11 Jul '09

Hey all, in case someone is interested here's my recently finished master thesis: http://grrrr.org/pub/grill-2008-master-2d_gesture_mapping.pdf or in very compact form, as a presentation poster: http://grrrr.org/pub/grill-2008-master-poster.pdf This thesis describes a novel, fairly general and (for the player) non-technical interface concept for software-based music instruments. The actual proof-of-concept instrument has been realized using pd and gem (with a number of optimized flext-based external objects to make it all possible on current hardware). gr~~~

[PD-announce] Pd workshops at Imal (Brussels/Belgium) in July and August
by Jack 19 Jun '09

19 Jun '09

Hello list, Sorry in french only. Premier workshop (4 jours) : PureData, une introduction du 28 au 31 juillet 2009 Contenu: Ce stage est une introduction à PureData dans un contexte de création visuelle en temps réel, ainsi qu'aux possibilités d'interaction et d'échange de données sur les réseaux. Après la révolution du montage vidéo numérique, la nouvelle (r) évolution est le traitement de la vidéo, de la 3D et des flux de données en temps réel. Utilisés aussi bien en performance (VJ, Live Cinema) que dans les arts de la scène (danse, théatre) ou dans les environnements interactifs, les nouveaux logiciels de traitement en temps réel sont aussi une autre manière de produire de la vidéo linéaire, de la 3D ou du son. Le stage explore un des principaux outils actuels: PureData + GEM, environnement 'opensource' de programmation visuelle créé par Miller Puckette. Pd est un équivalent gratuit de MAX/MSP permettant de nombreuses manipulations en terme de son, d'image, de vidéo, de 3D, d'interaction en temps réel, mais aussi en terme d'échanges de données sur les réseaux. Formateur : Jack/RYBN Deuxième workshop (4 jours) : PureData, 3D Temps Réel et modèles physiques du 3 au 6 août 2009 Contenu: Durant ce workshop de 4 jours, nous aborderons de manière pratique la modélisation physique et la synthèse 3D en temps-réel. Les librairies pmpd et msd pour PureData permettent de simuler des comportements naturels d'objets simples: cordes, membranes, fluides, sables, ... Ces librairies seront explorées pour différents usages: filtrage de signal, contrôle de la synthèse sonore, mais surtout elles seront employées pour la synthèse 3D en temps-réel dans GEM. Les participants du workshop apprendront dans un premier temps à créer puis à manipuler des structures modélisées. Puis des techniques avancées de dessin et de création graphique seront détaillées pour représenter les structures développées. Formateur : Nicolas Montgermont Conditions de Participation : Ces stages sont accessibles à tout artiste, étudiant en art, désigner, infographiste, vidéaste, programmeur, enseignant... désirant s'initier aux nouveaux outils créatifs issus du numérique (18 ans ou +). Inscription : Attention : le nombre de place est limité (max. 15 personnes), inscrivez-vous à temps en remplissant soigneusement le(s) formulaire (s) d'inscription en ligne du ou des stages que vous voulez suivre sur http://www.imal.org/AteliersArtNum ! Lieu : Les stages se donnent à iMAL, 30 Quai des Charbonnages, 1080 Bruxelles (le long du canal, métro Comte de Flandre). La classe est équipée d'ordinateurs en réseau (venez avec votre portable si vous en avez un), d'un vidéoprojecteur, et d'un tableau... Horaire : Les cours se donnent de 10h à 18h00 avec interruption d'une heure le midi. Les stages ont une durée de 4 jours. Prix : 140 EUR par stage. Liens : les stages d'été d'iMAL (descriptifs, formateurs, inscriptions, archives) : http://www.imal.org/AteliersArtNum ++ Jack _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

K8061 USB interface board in PD on Mac
by Wilfred de Zoete 16 Jun '09

16 Jun '09

Hello everybody, for some interface experiments I got hold of an USB interface kit from Velleman, the K8061. More info: http://www.velleman.be/ot/en/product/view/?id=364910 This board comes with software for windows computers, a.o. a .dll file for communication. My system is a MacBook Pro november 2008 with OS X 10.5.6. Are there people out there who have already used this board in Pure Data and/or on Mac OS X? I have already tried to get some data out of it with HID and although HID works good for joysticks and game controllers it does not get data from this kit. Thanks in advance! Wilfred

[PD-announce] Pd 0.42-5 released
by Miller Puckette 16 Jun '09

16 Jun '09

Pd version 0.42-5 is ready: http://crca.ucsd.edu/~msp/software.htm or via svn: svn checkout https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/pd/ Bug fixes: abs~, log~, pd~ -ninsig 0. The 32 channel limit for ASIO and on Mac is no longer imposed. A -noautopatch startup flag stops Pd from auto-connecting to new objects (which some people seem to hate :) cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce
