Re: [PD] settings on Ubuntu
Dear Derek, Derek Holzer wrote: Hi all, two of my students at a workshop today had the same problem. They installed Pd-ext from their package manager, but they have no preferences file thus no externals loaded, paths or anything. It is not clear how they installed Pd[extended]. Did they download a .deb file or did they install it straight from synaptic or the 'software center'? In the latter case latter chances are they actually installed Pd 'vanilla' and not pd-extended: in fact AFAIK pd-extended is not present in the ubuntu repositories. This would explain why they get no extra stuff. If this is the case they can get stable .deb package for all recent versions of ubuntu here: http://puredata.info/downloads (be sure to get pd-extended!) or autobuilds here: http://autobuild.puredata.info/auto-build/ Hope this helps. Bests, Lorenzo I scanned HC's page, the puredata.info FAQ and the list and didn't find anything about this. Did they forget/not know to do something or is this an error on the package manager's part?

Re: [PD] Linux Computer for mappping with GEM
Thank you for the advice, I really appreciate it.

For the capture card I was also worried about the latency so I will search for one with the bt8x8 chip, I don't know if it is easy because all the hauppauge I see for sale now are PCIe and say they have a new chip that I dont't know if it is working but I can always change it if doesn't work.

The Patching Circle got a residency at Eyebeam! So for the next three months, we'll be on a Thursday evening, starting this Thursday. And Miller Puckette, the creator of Pd/Max will be joining me as a guest host this Thursday and next month. Pure Data 0.43 is about to be released, so some of us will be working on finalizing that. It includes a major update to the GUI to enable lots of customization. You can now customize the Pd GUI using simple plugins. Come bring your projects or try out Pd 0.43. We'll be at Eyebeam this Thursday from 6-10pm, please RSVP to i...@eyebeam.org http://eyebeam.org/events/nyc-patching-circle inline: Photobucket.jpeg 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 , 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.

The DSP could very well be doing those transforms only once, but if Pd is the only app accessing the driver, the functions would only be in the Pd trace.

So, running the aforementioned RT kernel, managed to patch the latest nvidia driver following these general instructions: http://ubuntuforums.org/showpost.php?p=9233282postcount=5 I'm already happy because it's quite some time that i haven't had the RT kernel! As i don't use GEM i cannot tell about it, but Pd got faster. Almost as fast as the 32-bit Pd was (on 64-bit Ubuntu - Hardy that time). It means i can almost use my MIDI sequencer patch without the GUI dropping out. Promising! Now i can dig into the patch for optimisation possibilities, and at the same time, keep on bugging the community for speeding up the GUI :o) Do you guys think i shall try it with a current 32-bit Pd to see if the 64-bit version is really slower...?

Re: [PD] HHT HilbertHuangTransform objects in Pd?
I even mean a third algorithm... I am focused more the empirical mode decomposition put forward by Huang, ... after splitting the signal in IMFs they are individually analyzed by Hilbert transform, or other time frequency transform of choice... Im more looking to EMD, but I just found some matlab code which octave seems to be able to run, and theres some C functions... going to look how achievable it is, and going to ask permission from the author to make Pd externals based on them... ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Which Linux distribution are you using?
Hi, I have installed Ubuntu 10.04 LTS, plus some ubuntu studio stuff (the audio packages and the plugins). I also tried the rt-kernel. It didn't work. But i am amazed, blown away, baffled, etc. Because the generic kernel does have some crazy rt capabilities indeed. I guess the ubuntu studio packages must have created the audio group and jack must have written the proper things in the limit file, but still, it works surprisingly well. Jack can run in rt with a latency as low 4 ms without any xruns, although it crashes.It works just fine at 5.33 ms. Even pd itself work with an extremely low latency (I'd say below 7 ms), I'm assuming that's because it was configured to run in rt during the install. I don't even know if i need JACK anymore. Does any of you know how i can measure the actual latency in Pd? I couldn't tell by ear which config was faster, Pd alone or Pd plus JACK. Looks like it time to say goodbye to rt-kernels... This makes me happy. Cheers! Pierre 2010/11/15 András Murányi muran...@gmail.com So, running the aforementioned RT kernel, managed to patch the latest nvidia driver following these general instructions: http://ubuntuforums.org/showpost.php?p=9233282postcount=5 I'm already happy because it's quite some time that i haven't had the RT kernel! As i don't use GEM i cannot tell about it, but Pd got faster. Almost as fast as the 32-bit Pd was (on 64-bit Ubuntu - Hardy that time). It means i can almost use my MIDI sequencer patch without the GUI dropping out. Promising! Now i can dig into the patch for optimisation possibilities, and at the same time, keep on bugging the community for speeding up the GUI :o) Do you guys think i shall try it with a current 32-bit Pd to see if the 64-bit version is really slower...? (on a side note to RT kernel experiences: the CPU got hotter indeed, looks like i'll have to tweak the cooling fans again...)

I don't even know if i need JACK anymore. jack don't add latency, and it's a powerfull sound server... you can connect pd to the outputs of your sound device and/or other sound/midi softwares, then you can save a patchbay to recover your patch... it's one of the most interesting stuffs on linux. Does any of you know how i can measure the actual latency in Pd? have a look on jdelay: a simple jack command-line latency-meter. when you start it, a new client appears in jack: connect it between pd out and in, connect in and out in a pd patch, you'll get a time in frame: frame/frequency = t in sec (ex 480 / 48000 = 0.010 = 10 ms). You can connect it between sound device in and out and plug a jack between out and in, you'll get the real round latency... you will have to compile it, README explains all... I couldn't tell by ear which config was faster, Pd alone or Pd plus JACK. maybe I'm wrong, but I thing only jack can provide rt... cheers, r Looks like it time to say goodbye to rt-kernels...

[PD] [PD-announce] /dev/art/#3 in Paris with Derek Holzer - Friday november, 19
In french only (désolé pour le même mail provenant de différentes listes !). Pour une meilleure mise en page, vous pouvez consulter le PDF joint à ce mail : /dev/art/#3 Rencontres, discussions et échanges entre artistes et développeurs utilisant les nouvelles technologies de programmation (arts numériques, hacking, performances, etc.). Le vendredi 19 novembre / 19h-23h au BlackBoxe 17 rue de la Chapelle / 75018 Paris Metro ligne 12 / Station Marx Dormoy ou Porte de la Chapelle 19h / 21h : rencontres, discussions et échanges autour des arts numériques, de la performance, du hacking et du développement d'applications et d'installations. 21h / 21h30 : Pot/apéro 21h30 / 23h : performance + présentation de Derek Holzer : ToneWheels Installé à Berlin, Derek Holzer est un artiste américain passionné par la fabrication de ses propres machines analogiques, le field recording et les musiques expérimentales. Habitué des performances sonores, il viendra présenter son étonnant projet ToneWheels. ToneWheels, est une expérience de conversion d'image graphiques en sons, grâce à l'utilisation de disques transparents dont les motifs imprimés sont lus par des capteurs de lumières pour créer des textures sonores et visuelles. Performance totalement live et hardware analogique, ToneWheels cherche à révéler au public le processus de création et de construction de la performance elle-même. Derek Holzer is an American sound artist living in Berlin, whose current interests include DIY analog electronics, sound art, field recording and the meeting points of electroacoustic, noise, improv and extreme music. He has played live experimental sound, as well as taught workshops in noise art technology. He comes in Paris to present his project ToneWheels. ToneWheels is an experiment in converting graphical imagery to sound, inspired by some of the pioneering 20th Century electronic music inventions. Transparent tonewheels with repeating patterns are spun over light-sensitive electronic circuitry to produce sound and light pulsations and textures. This all-analog set is performed entirely live without the use of computers, using only overhead projectors as light source, performance interface and audience display. In this way, ToneWheels aims to open up the “black box” of electronic music and video by exposing the working processes of the performance for the audience to see. texteDevArt3.pdf Description: Adobe PDF document ___ Pd-announce mailing list pd-annou...@iem.at http://lists.puredata.info/listinfo/pd-announce ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
