Good programming practice
by rodney 23 Oct '04

23 Oct '04

HI all, After a quick search through the archives, this is the link provided from an earlier discussion with the above subject. http://www.earcatching.com/pdconv/ Pd allows a lot of different 'styles' of programming, some better for some things than others. All I know is that my style has left me strangled in invisible spagetti and hope to improve it by looking at how everyone else does it. Rod.

Graph-on-parent bug?
by Thomas Sivertsen 23 Oct '04

23 Oct '04

Hello list. I've been experimenting with graph-on-parent and hit a small snag. It seems whenever I open a patch which has a HRadio object in a subpatch, it will move the HRadio way out to the right and mess up my nice interface. This is with PD 0.37.4 on Linux, reproducible on 0.37.1 on Windows too. Am I right that it has something to do with the internal scale of the sub-patch? Changing it in the properties of the subpatch has no effect. Also, why do I have to guess where to put my interface objects so that they end up in the right positions? I posted a patch earlier which exhibits the problem (flake.tar.gz/flake-0.1.pd). Not a big problem, but annoying if you want consistency... :-/ Any workarounds? .thomas

Got a laptop, completely new to Linux and wanting to try pd with it and kind of still want to use XP just in case. Well, I went for Fedora Core 1 then and was eventually made it to core 2. Well fedora because I have heard of red hat and someone pointed me to planetccrma which supports it. With apt-get (in Debian too) plus synaptic, installing packages was straight forward. Although I do believe that jack and FC2 ccrma kernel is not perfect yet. Having said that. I have been using jack quite a bit lately on my FC2 and works good. No problem with dual boot either, installing both FC1 and FC2 was simple, no fuss. FC community was helpful too, got quite a bit of help in the beginning. Oh, there are quite a few book around on fedora 1 and 2. In fact, I got my first install disks from a fedora book. AGNUlA/Demudi sounds very interesting, will have to check that out soon. That's all for now I think Yours CHUN

High All m_pd.h is is the ...resources/src in my version of 38-test4-hcs Perhaps you should check that you did actually get a complete download. I ended up with only half an app once even though it unzipped properly it definitely wasn't all there. .dmg is 9.8Mb Total app size for me is 44Mb - cant remember if I've added anything yet - My src folder has 113 items - Will see if I can help when I reinstall Developer Tools.

Any working Win32 OSC binary? Or help compiling...
by Peter Todd 22 Oct '04

22 Oct '04

Hello, I've been using pd in windows for a while, and have never had a working binary of OSC. I used to have one that printed an error message in the console whenever I ran pd (maybe it worked for other people), but that's not terribly useful. I have tried building it from the visual studio workspace of the version on CVS, without any luck (it is not my own copy of vstudio, and I'm not particularly experienced in using it). It was a few weeks ago I was trying this, and I could have been more systematic about it (so I don't remember clearly), but this is roughly what I tried. I modified the project preprocessor to include the pd/src directory for m_pd.h. The names of source files in the project didn't even always correspond to the actual file names, so I removed 'routeOSC.c' from the project and added 'OSCroute.c' - there may have been other changes that I don't remember. For good measure, I also added the 'libOSC' project to the 'OSC' workspace, and made the OSC project dependant on it. I still get compile errors, though - can anyone direct me any further? Of course, a working binary would be fine. I must admit that I've tried vaguely to compile a few of the pd externals for myself with no luck - this one I'm actually lacking a working copy of, though. I'm sure there are all kinds of straightfoward things I'm missing (and no doubt at least one stupid thing I am doing). Thanks, Peter p.s. here is the output I get in visual studio, fwiw. --------------------Configuration: OSC - Win32 Debug-------------------- Compiling... dumpOSC.c c:\documents and settings\peter\workspace\oscx\src\dumposc.c(80) : warning C4273: 'sys_addpollfn' : inconsistent dll linkage. dllexport assumed. c:\documents and settings\peter\workspace\oscx\src\dumposc.c(137) : error C2632: 'long' followed by 'long' is illegal c:\documents and settings\peter\workspace\oscx\src\dumposc.c(323) : error C2054: expected '(' to follow 'OSC_API' c:\documents and settings\peter\workspace\oscx\src\dumposc.c(327) : error C2085: 'dumpOSC_setup' : not in formal parameter list c:\documents and settings\peter\workspace\oscx\src\dumposc.c(327) : error C2143: syntax error : missing ';' before '{' c:\documents and settings\peter\workspace\oscx\src\dumposc.c(488) : warning C4013: 'printf' undefined;

PD / P5 Glove
by Macciza Macpherson 22 Oct '04

22 Oct '04

High All, Haven't written in a while but interested in catching up with anyone who has been mucking about with the P5Glove, Particularly those on OSX. Or just anybody working with any sort of alternate controller. On a side node, a recent disk crash caused me to have to do a lot of work recreating PD. My problem was needing the OSC stuff as thats how the glove communicates on Mac. But it was a very longwinded affair. I had previously built versions, got the Puckette.app versions etc and coalesced a good system and had been able to implement the glove as a theremin in 5 minutes. This time around with out the luxury of being able to build anything, it to several binary versions, attempted mergings as well as different .app versions before the Pd-0.38-0test4HCS1 version came up as the best base candidate. Can't quite remember the specifics of this vers but it implements OSC perfectly Doesn't seem to be in test4 or test7. No to try and customise it all again. Cheers All, Macciza.

by Michael Berkowski 22 Oct '04

22 Oct '04

Greetings everyone, Our apologies for cross-posting. Here is the official festival announcement and call for works/papers of the 3rd annual Spark Festival of Electronic Music and Art. Note: The original call for Spark 2005 listed an incorrect URL and email address. The correct contacts are www.spark.cla.umn.edu and sparkfst(a)umn.edu. The Spark 2005 website will activate on October 19. University of Minnesota School of Music, Noel Zahler, Director Announces 2005 Spark Festival of Electronic Music and Art, Douglas Geers, Director West Bank Arts Quarter, University of Minnesota Twin Cities Campus February 17-20 CALL FOR COMPOSERS, ARTISTS, and PRESENTERS Submission Deadline: November 22, 2004 (postmark) The University of Minnesota School of Music is proud to present the 2005 Spark Festival of Electronic Music and Art, February 17-20. The festival will be held at the West Bank Arts Quarter on the University of Minnesota, Twin Cities campus. Now in its third year, the Spark Festival showcases the newest groundbreaking works of digital music and art. Last year's festival included innovative works by over sixty international composers and artists. Leading scholars and technology specialists also presented papers relating to new technology and creativity. Spark invites submissions of new works incorporating new media, including electroacoustic concert music, experimental electronica, theatrical and dance works, installations, kinetic sculpture, artbots, video, and other non-traditional genres. Spark also invites submission of scholarly papers on technical and aesthetic subjects related to the creation of new media art and music. All accepted papers will be published as part of the Spark proceedings. MUSIC SUBMISSIONS Music submissions will be accepted in four categories: 1. Concert works: Electroacoustic works with and without performers. Performance venues will accommodate 2-8 channel works and works with video. Although there is no strict limit of duration, pieces of twelve minutes or less are encouraged. 2. "Club" works: Experimental electronic performances in a "club-style" venue. Selected performers will be given sets of 15-30 minutes. Performance venue will accommodate stereo sound and video. 3. Installations: [See "Visual Art Works" below] 4. DJ battle: A select number of DJs will be selected to compete in a one-evening event in which two winners will be selected: (1) most virtuosic and (2) most unique. Note that prizes will be symbolic (not pecuniary!) in nature. VISUAL ART WORKS Visual submissions will be accepted in three categories: 1. Installations and gallery works: A number of installation and gallery exhibitions will be mounted in various spaces on the UMN campus.

GoP, IEM GUI, "label_pos" bug
by David NG McCallum 22 Oct '04

22 Oct '04

I just noticed something very screwy. If a GUI object is sent a "label_pos" message when it's in a GoP patch (abstraction or subpatch), the label seems to be drawn relative to the GUI's position as if it were in the parent patcher, not the GoP patch. I'm using .38t7 in Linux. I've attached an example.
