Looking for a Pd tutor in the Bay Area
by multiplicity1＠netscape.net 18 Dec '05

18 Dec '05

I would like to get some hands on training on the use of Pd. I am in the San Francisco/Bay Area. I am looking for a tutor who lives in the East Bay (Berkeley, Oakland, Albany, Pinole, Hercules, etc.) who would be willing to tutor a seriously new newbie. If anyone is interested please let me know. d. boone ___________________________________________________ Try the New Netscape Mail Today!

hi all, i am looking for an abstraction or external...something like polygate (motex) but just the oposite. -switch between multiple signal outputs. any ideas? thanks, steve. www.soundmuseum.de

weird. i just downloaded and installed 0.38.4 RC6 , and i thought "yeah, you can open help menus now without having a blank patch opened" but then i put org.puredata.pd.plist in my library/preferences and this function stopped. so i guess that's where the bug is.

The Party at the Center of the Universe

Escape velocity is a natural consequence of the inverse-square force (gravity or electricity)." The magnetic field's force in a plasma is decreasing following the inverse of the distance and not the inverse-square, and plasma is filling 99 % of the universe or the area outside the atmosphere of a planet. A team of astrophysicists is severely doubting galaxy formation caused by gravity and implies the force of electromagnetic field since the Nobel Prize Hannes Alven and his plasma universe theory. Trying to make an emulation of a plasma seems merely difficult to do because the computer or the supercomputer would have to control each particle in the plasma, for example a solar exposion, but maybe there are other solutions if anyone has an idea... patco

Re: [PD] dynamic stochastic synthesis in pd?

Ok, everyone, I've attached two zip files with several patches in them. strange attractors.zip contains the patches of interest dglibpd.zip contains abstractions needed to run these patches and many more basic utility abstractions I use in many patches I also depend on [alternate], probably the only external you'll need. If you don't have it you can probably make do with an abstraction - it has one inlet and two outlets, and when banged, a bang comes out of each outlet alternately. This is such a simple external I don't know why anyone bothered to code it, but it's very useful all the same. Let me know if you find these patches confusing or difficult to operate - I'd gladly take some suggestions. Enjoy. David

Playing with the new data structure features
by Frank Barknecht 17 Dec '05

17 Dec '05

Hallo, hm, I really like the additional features of data structures. The scaling, although a bit awkward to use or to get into, gives some nice new possibilities. Some are illustrated in attached patch. I think, one major advantage now is, that ranges can be restricted, something that came up here as a feature wish a couple of times. It could be nice to also include this for [drawnumber], which currently doesn't work. Also thanks to the scaling it now is possible to have "inverted" ranges, which as in attached slider example often is more natural to use. Switchable visibility can be used for nice effects, too, and might be useful in conjunction with the new selection feature as well. Visibility switching however doesn't work correctly with [drawnumber] yet, which can be demonstrated by adding a "-v vis" to the [drawnumber ...] instruction in the slider template: Numbers don't get deleted correctly, when their visibility is switched off. I didn't yet play a lot with the selection feature yet, apart from looking through the help and example patches. It also looks immensly useful, because it provides a kind of callback on editing operations through the pointer sent by the [struct]. However the current mechanism doesn't allow one thing, that could be useful as well: If I change the value of some graph, while I'm not in edit mode, there still is no direct feedback. OTOH when I'm in edit mode, I can select an object and get this feedback, but I cannot change its data fields unless I leave edit mode again. With all this, I see that I can make a lot of cool enhancements to my msd-editor, which unfortunatly have to wait another week. ;) Ciao -- Frank Barknecht _ ______footils.org__ _ __latest track: "plak" @ http://footils.org/cms/show/44

HID woes, continued
by august 17 Dec '05

17 Dec '05

I just checked out a copy of the the [hid] object and again it is crashing as soon as I try to start it. The old object that I have modified to work with my setup still works fine, so I can use it. ( I forgot what the changes where, but I believe I sent them to you a while back.) It seems like the error is coming from changes in input_arrays.c If you tell what these are all about I might be able to debug it. -august. ------------------- http://aug.ment.org

hi , can you explain how have you been using those chaotic equations for sound synthesis? have you been using them for the generation of sound itself? i been investigating about this.... in the stochastic synthesis as convieved by xenakis , stochastic laws are used to generate the succesive sample amplitudude values of digital sound. how can i use the numbers from one the pd chaos objects to determine sample amplitude values and the interpolation between them. how can this be achieved in pd? how can i calculate interpolation between samples? the idea is to use each couple of numbers (x-y axis?)from the chaotic attractor to control the lenght(how many samples?) of a segment (sucession of samples) and the last sample amplitude value of the segment... the sample values inside my segment are gonna be calculated by interpolation. any hint? yukio > i been experimenting using chaotic equations and strange attractors to > control some synthesis parameters, but i now im more interested of > using them as a source for direct sound synthesis. i haven't been implementing any of the gendy algorithms, but i've been using other kinds of chaotic equations for sound synthesis ... the sources for my external are available on the cvs: http://cvs.sourceforge.net/viewcvs.py/pure-data/externals/tb/chaos/ > for exampe i was trying to use the numbers resulting from those > equations as a waveform using sig~ object with no luck. i just get > some clicks . > can anybody explain me how can i get sonorous signals from those > numbers? is there any special math or trick? i've been using 0 different kinds of interpolation between samples ... sample&hold, linear and cubic ... but one thing is the interpolation, the more complex problem is to find parameter values that give a decent behaviour ... cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

Demos Although brief demonstrations can be shown during paper sessions, NIME 06 will give the possibility to schedule demo presentations in dedicated demo sessions. The submission procedure will allow to choose an explicit demo option for any paper or poster submission. The simplest demo submission would take the form of a short poster summarizing the scientific/technical aspects, acquired experiences and/or the context of the development. For presentations of commercial products and companies not associated with a conference submission, there will be exhibit booths. Please contact Vincent.Puig[at]ircam[fr]. ------------------------------------------------- LIVE PERFORMANCES An evening concert during the conference will be dedicated to live performances hilighting creative use of interactive instrument technology. We welcome proposals for performances to be featured in the NIME 06 concert. Please refer to the NIME 06 web page for detailed submission requirements. -------------------------------------------------- INTERACTIVE INSTALLATIONS Various spaces in and around the conference venue are reserved for interactive sound and multimedia installations. We welcome proposals for interactive installations to be presented during the conference. We particularly encourage installations that could run during the entire period of Agora/R?sonances from June 1 to June 17. While some of the spaces are closed rooms, others are open spaces such as entrance or stairs which encourage site-specific installations. Please refer to the NIME 06 web page for detailed submission requirements and descriptions of the provided installation spaces. --------------------------------------------- COMMITTEE Conference Chairs Norbert Schnell (IRCAM) Frederic Bevilacqua (IRCAM) Paper and Poster Chair Michael Lyons (ATR Kyoto) Performance and Installation Chair Atau Tanaka (Sony CSL Paris) Demo Chair Emmanuel Fl?ty (IRCAM) Proceeding Editor Marc Battier (MINT-OMF Sorbonne) Administrative coordinator Sylvie Benoit (IRCAM) NIME Steering Committee Ivan Poupyrev Michael Lyons Tina Blaine Atau Tanaka Joe Paradiso Marcelo Wanderley Sile O'Modhrain Sidney Fels Yoichi Nagashima -------------------------------------------------------
