pd-gui update rate
by Roman Haefeli 18 Nov '11

18 Nov '11

Hi all I would like some GUI elements in a patch to refresh with the highest rate possible, but at the same time also as economic (in terms of CPU usage) as possible. How can I know at which rate a Pd canvas is updated so that I can adjust the gui update accordingly? Matju directed me to the respective parts in the source code, but I was not able to make any sense out of it. I've come so far yet: In src/m_sched there is 'void sched_tick' which (afaict) runs the 'while' loop that runs the whole Pd DSP and GUI stuff. It seems that every 5000 clock ticks, the whole GUI is refreshed (sys_pollgui()). But how long is such a tick? Can someone make more sense out of it? Roman

emulate mouse click with msg
by Joe Newlin 18 Nov '11

18 Nov '11

I'm experimenting with dynamic patch creation and GEM and I would like to be able to send a "draw line" message to objects in thousands of subpatches. I came across this, which mentions sending a "click" message, apparently to coordinates within the subpatch: http://lac.linuxaudio.org/2009/cdm/Saturday/18_Zmoelnig/zmoelnig_pdreflecti… But for message that was created at the location 100 100, for example, I would expect that sending the message "click 101 101 0 0 0" (not sure what the five floats represent exactly) would represent a click within the message object. But it doesn't mean that, apparently, because it hasn't worked yet. Please help me understand the click message syntax. Thanks, JN -- www.joenewlin.net www.twitter.com/joe_newlin

[PD-announce] [Workshop] Xth Sense Biophysical Generation and control of music CultureLab Newcastle
by Marco Donnarumma 18 Nov '11

18 Nov '11

(sorry for x-post) Last call for participation. //// ONLY two places left \\\\\ ~ Xth Sense – biophysical generation and control of music Hands-on training in augmentation of the body for musical performance. Creating your own low cost biosensing wearable device for muscle sounds. See an Xth Sense performance at http://vimeo.com/20889787 Xth Sense: http://res.marcodonnarumma.com/projects/xth-sense/ http://marcodonnarumma.com/works/music-for-flesh-ii/ ~ When & Where Space 4/5, Culture Lab, Grand Assembly Rooms, King's Walk, Newcastle, NE1 7RU Monday, 21st November 2011 at 09:00 Friday, 25th November 2011 at 22:00 SIGN UP HERE: http://tinyurl.com/xthNCL Workshop outline: http://marcodonnarumma.com/teaching/xth-sense-biophysical-music/ ~ What The workshop offers an hands-on experience and both theoretical and practical training in gestural control of music and bodily musical performance, deploying the brand-new biosensing technology Xth Sense. Developed by the workshop teacher Marco Donnarumma within a research project at The University of Edinburgh, Xth Sense is a framework for the application of muscle sounds to the biophysical generation and control of music. It consists of a low cost, DIY biosensing wearable device and an Open Source based software for capture, analysis and audio processing of biological sounds of the body (Pure Data-based). Muscle sounds are captured in real time and used both as sonic source material and control values for sound effects, enabling the performer to control music simply with his body and kinetic energy. Forget your mice, MIDI controllers, you will not even need to look at your laptop any more. The Xth Sense biosensor was designed to be easily implemented by anyone, no previous experience in electronics is required. The applications of the Xth Sense technology are manifold: from complex gestural control of samples and audio synthesis, through biophysical generation of music and sounds, to kinetic control of real time digital processing of traditional musical instruments, and more. ~ How Firstly, participants will be introduced to the Xth Sense Technology by its author and led through the assembling of their own biosensing wearable hardware using the materials provided. Next, they will become proficient with the Xth Sense software framework: all the features of the framework will be unleashed through practical exercises. Theoretical background on the state of art of gestural control of music and new musical instruments will be developed by means of an audiovisual review and participatory critical analysis of relevant projects selected by the instructor. Eventually, participants will combine hardware and software to implement a solo or group performance to be presented during the closing event. At the end of the workshop, participants will be free to keep the Xth Sense biosensors they built and the related software for their own use. ~ Perspective participants The workshop is open to anyone passionate about sound and music. No previous experience in electronics or programming is required, however participants should be familiar with digital music creation. Musical background and education does not matter as long as you are ready to challenge your usual perspective on musical performance. Composers, producers, sound designers, musicians, field recordists are all welcome to join our team for an innovative and highly creative experience. This is a last call for only two more candidates. Feel free to forward to your networks. thanks, best wishes, -- Marco Donnarumma Independent New Media and Sonic Arts Practitioner, Performer, Teacher ACE, Sound Design MSc by Research (ongoing) The University of Edinburgh, UK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Portfolio: http://marcodonnarumma.com Research: http://res.marcodonnarumma.com | http://www.thesaddj.com | http://www.flxer.net Director: http://www.liveperformersmeeting.net _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

<<Loaded>> event
by Jonathan Wilkes 18 Nov '11

18 Nov '11

Hi Hans, I'm close to finishing a revision of my tooltips patch. To properly loadbang a canvas tip I need something like a <<Loaded>> event, but one that tells me when the a pd patch window has finally finished being drawn by Tk. <<Loaded>> seems to trigger once the procedure for creating a new canvas has finished (technically right before, I guess), but it doesn't tell me when Tk has actually finished drawing the window and setting all the window dimensions that are query-able through winfo. I think I could use <Configure>, but it will trigger multiple times-- I just want one event that tells me "Ok, everything that needed to get drawn as a result of creating this patch window is done drawing." (tcl/tk wiki warns against "update idletasks" which can cause subtle bugs.) -Jonathan

Sofy is hosting us again at the new space, 319 Scholes, in East Williamsburgh, right around the corner from 3rd Ward. We'll also be there the next month on Tuesday 12/20. Join us to patch your way to delicious turkey or tofurky or whatever you're going to eat! http://puredata.info/community/NYCPatchingCircle We spend enough time alone staring at our computers; we are proposing to work together. So often issues that arise when working can be solved with a quick two minute discussion that would take hours to solve alone. We have Dorkbot to see people's work, we have Share where anyone can play, we have workshops and universities to learn from. This is a meeting where we all can come to work. This is an informal gathering of patching and patchers (Pd, Max/MSP/ Jitter, and even vvvv, Eyesweb, Labview, etc.). Beginners and Experienced welcome. Open to everyone, students, the public, etc. Work on personal projects, professional projects, school projects, ask for help, help others, or just patch quietly to yourself, in a room full of other people patching patches and helping other people patch. Tuesday 11/22, 6-9pm Free! Directions ---------- Patching Circle, http://puredata.info/community/NYCPatchingCircle 319 Scholes, http://319scholes.org/ 319 Scholes St (near 3rd Ward) Brooklyn, NY 11206 917 755 0390 (Sofy) Mailing List ------------ We also now have a mailing list for announcing the meeting each month, its very low traffic, only the monthly announcements. Sign up here: http://mailman.at.or.at/cgi-bin/mailman/listinfo/nyc-patching-circle _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Troubles running Pd-0.43.1test5 on Windows XP
by Roman Haefeli 17 Nov '11

17 Nov '11

Hi all Has anyone tried to run the last release of Pd (Pd-0.43.1test5) on Windowx XP? I fail to even start it. Double-clicking either pd.exe or pd.com does just nothing. When calling pd.com from the cmd shell, I get this output: C:\pds\pd-043.1test5\bin>pd.com spawnl: Invalid argument C:\pds\pd-043.1test5\bin\wish85.exe: couldn't load TCL Is it only me, or is this release really broken on Windows XP?
