pd message order?
by Ludwig Maes 04 Aug '11

04 Aug '11

so standard objects have right to left ordering of outlet processing, but what about send and receive for messages? if multiple objects receive for the same name, which one gets it first? is there a triggerlike object for messages, or should I send multiple messages each with a differentiated tag like s bla1, s bla2, s s bla3 even when I send the same message?

Re: [PD] Soundfiler / ram
by Jean-Marie Adrien 03 Aug '11

03 Aug '11

Thanks for yor message Hans-Christoph ! so to confirm : Given say 50 presets with each 250 samples some of them read direct from disk and others in arrays for looping and so on. Presets do not need to switch instantly, loading might take few seconds. But switching a large number of times as installation runs, has to be clean though. Good way to implement this would be : declare a number of arrays (corresponding to the largest preset) when loading the patch and resizing / reloading them for preset change ? (I do not want to choose a bad option from the beginning !) cheers, JM Le 30 juil. 11 à 20:20, Hans-Christoph Steiner a écrit : > > There is the 'resize' message to send to an array to resize it, or > the -resize option to the 'read' message to soundfiler.

[PD-announce] Pd Convention - Data structures workshop: Taking your requests
by João Pais 03 Aug '11

03 Aug '11

Hello everyone, in the first 2 days of the Pd Convention I will be giving a workshop about data structures - http://www.uni-weimar.de/medien/wiki/PDCON:Workshops/Data_Structures. My plan is to talk about the theory in the first session, and practical implementations + patch analysis in the second session. I have already a group of example patches ligned up, but I wanted to see if anyone has their own desires. So, if you are interested in coming to the data structures workshop, and already have a goal in mind on where/how to use them, you can send me your requests. If time is available, I might be able to do some work for you, which you can afterwards develop further. If you want to send me a patch, try to follow the following steps: - describe to me what the patch does, possibly leaving some comments inside near some important parts - describe what you wish to do And for everyone else: I would also like to know who will come to my workshop. In case you have time, just send me a small message privately with: - your name - your interests - your experience level Hope to see many of you next week, João Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 Studio +49 30 69509190 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

find a list of numbers in a text file
by Alexandre Torres Porres 03 Aug '11

03 Aug '11

Hi folks Back in the end of my masters, I did make something that allows you to load scales from the Scala software into Pd, which has a database of over 4000 scales. Check the software and data bank here http://www.huygens-fokker.org/scala/ It's an extremely powerful tool for microtonality, but you may not care for that and just want to use the scale data bank in Pd. Anyway, I have a way that exports the from the Scala software into a text file that opens in this specific subpatch of mine. But I was trying to do something easier, and that is just load these *.scl files into [textfile] or [msgfile] for example, and extracting the list of these scale intervals in cents. Here's what one of these files look like ============== ! 08-11.scl ! 8 out of 11-tET 8 ! 218.18182 327.27273 436.36364 654.54545 763.63636 872.72727 1090.90909 2/1 =============== So I assumed it'd be easy to extract each cents value and make a list out of it, but I was wrong. Don't know why but it doesn't load this in separate lines, maybe because it is not a *.txt file at all. And anyway, I'm getting in Pd just a list, so the above file, for example, file becomes list ! 08-11.scl ! 8 out of 11-tET 8 ! 218.182 327.273 436.364 654.545 763.636 872.727 1090.91 2/1 I seem to have found a messy way to get the list out of it, but maybe you people know of something really simple and elegant with some extended objects. Thanks Alex

[PD-announce] EAT: A New Abstraction Package
by Rich Thomas 02 Aug '11

02 Aug '11

Dear list, (This is my first post to you, but I have long since been a follower.) I would like to introduce a new abstraction package called ElectroAcoustic Tools (EAT). EAT is a new set of abstractions for composition and diffusion that are currently under development in Pure Data Extended 0.42.5. EAT is accessible for preliminary educative use, but it also embraces the advanced functionality that Pd can provide for digital signal processing effects and spatialisation. You can download the package on Source Forge: https://sourceforge.net/p/eatpuredata/ This is a small first release to test the framework and functionality and I would be very grateful of any feedback that you feel able to provide on any aspect of the project. You can see my presentation on EAT at the Pd Convention in Weimar on 9 August at 1100. I hope that you find them to be a useful contribution.

Pitch Shift
by Alexandre Torres Porres 02 Aug '11

02 Aug '11

Hi folks, so, what are the options out there for Pitch Shifting? I usually use the Phase Vocoder, but there is an inevitable little bit of delay and the buffer issue. But the Pitch Shift example (G09.pitchshift.pd) sounds terrible next to the phase vocoder, I think. And, well, basically I'd like to keep the same length, just like the phase vocoder, so what do you say? thanks

pd-vanilla on gumstix overo with ubuntu 11.04 hangs with watchdog: signaling pd...
by olsen 02 Aug '11

02 Aug '11

Hi i compiled Pd-0.43.0 on a gumstix overo running ubuntu 11.04 armel distro. I patches the sources as stated in this thread: http://lists.puredata.info/pipermail/pd-list/2011-04/088163.html but starting pd releases the watchdog from the doghouse resulting in a stagnancy of "watchdog: signaling pd..." messages. i also tried the -noaudio option or -nogui option and pd-0.42-6 but all the same result... due to my research the watchdog thing has something to do with cpu consumption though as there's no dsp happening yet i don't know how to convince pd not to use that much cpu - or is there any configure option for arm processor that i missed? similar settings on the angström distro works out but there're other non pd things missing. any hint welcome ø olsen@retortenheber:~/pd/pd-0.43-0/bin$ ./pd -verbose Pd-0.43.0 ("") compiled 13:14:49 Aug 1 2011 port 5400 TCL_LIBRARY="../lib/tcl/library" TK_LIBRARY="../lib/tk/library" wish "../tcl//pd-gui.tcl" 5400 was... 1 Waiting for connection request... ../bin/pd-watchdog ... connected OSS: issuing first ADC 'read' ... ...done. watchdog: signaling pd... watchdog: signaling pd... olsen@retortenheber:~/pd/pd-0.43-0/bin$ ./pd -verbose -noaudio Pd-0.43.0 ("") compiled 13:14:49 Aug 1 2011 port 5400 TCL_LIBRARY="../lib/tcl/library" TK_LIBRARY="../lib/tk/library" wish "../tcl//pd-gui.tcl" 5400 was... 1 Waiting for connection request... ../bin/pd-watchdog ... connected watchdog: signaling pd... watchdog: signaling pd... -- ETs DNA will not be televised http://hasa-labs.org
