Re: [PD] Microsound

The classic reference is "Microsound" by Curtis Roads (one of the references in the Wikipedia article), although some of the math is pretty advanced. http://mitpress.mit.edu/catalog/item/default.asp?ttype=2&tid=10389 There's also a mailing list dedicated to Microsound that you might want to subscribe to, although it doesn't seem very active these days: http://www.microsound.org Good luck with PD and Microsound! > On Mon, Oct 18, 2010 at 3:54 AM, Nic Freed <beatthefinalboss(a)gmail.com>wrote: > >> Hi, my name is Nic, and I am 15 years old.

pix_film buffering
by William Brent 18 Oct '10

18 Oct '10

Hi, Can someone help me get a basic idea of how pix_film buffers video files? I made a patch for cueing up sections of a large video (60 minutes, at a ridiculous resolution of 3840 x 1080), and I'm wondering if there's anything I should be aware of in order to minimize the delay involved with jumping to specific points. Does pix_film buffer a certain number of frames before it starts playback? I'm using [line] into the right inlet to play through the requested range of frames. -- William Brent www.williambrent.com “Great minds flock together” Conflations: conversational idiom for the 21st century www.conflations.com

pix_filmDarwin
by William Brent 18 Oct '10

18 Oct '10

Hi, Sorry if this is common knowledge, but I can't find any information about pix_filmDarwin. The regular pix_film has always seemed to work fine for me, but maybe pix_filmDarwin is the natural selection for Mac OS 10.6.4?

Clearing a delwrite~ (revisited)
by Tyler Leavitt 17 Oct '10

17 Oct '10

http://www.mail-archive.com/pd-list@iem.at/msg00287.html I googled my question and came up with this thread... considering it was 4 years old I figured maybe someone out there had a fresh solution... I need to clear a delay that I have written via delwrite~. Is there any way to do this yet? Tyler

Segmentation Fault when loading videos
by Antonio Roberts 17 Oct '10

17 Oct '10

I've made a very simple video mixer in PD/Gem but I'm having problems with it. When I've loaded the videos (tried a combination of avi and mov files) and rendered the window after about 1 minute PD crashes completely with a segmentation fault: "WARNING: Child process terminated by signal 11" At first I thought it was because I'm using a proprietary graphics driver, but I disabled it and PD still crashes. I'm using pd-extended 0.42.5 on Ubuntu 10.10. System specs: Dell Studio 1555: Pentium Dual Core T4300(2.1GHz,800MHz,1MB), 4096MB 800MHz DDR2 Dual Channel, 512 MB ATI Mobility RADEON HD 4570

[PD-announce] Workshop: Starting with Sensors and Interaction, @ ACADIA conference
by Hans-Christoph Steiner 17 Oct '10

17 Oct '10

http://www.acadia.org/acadia2010/workshops 11- WORKSHOP TITLE: Starting with Sensors and Interaction Instructor: Hans-Christoph Steiner (hans(a)eds.org), Interaction Designer and Artist; Pd, Arduino, and Firmata Developer Administrative Support: Duration: 1 Day Date: Wednesday, 20th (10am-5pm) of October of 2010 Theme: Using Pd and Arduino to create real-time interaction The combination of sensors and computers provide myriad opportunities for creating interactions. This workshop will introduce how to use computers and sensors to generate real-time interaction in the physical world with light and movement. Pd (aka Pure Data) will be introduced as a simple programming enviroment for real-time interaction. Arduinos running Firmata software will be used to interface to the sensors, electronics, servos, etc. This workshop will be a combination of short lectures, hands-on instruction, and unstructured time to work on learning and exploring with support of the instructor. While Pd is fairly easy to learn and designed for artists, familiarity with basic computer programming will be very beneficial. You will be able to apply the concepts learned in this course to a wide range of programming environments where Arduino / Firmata is supported, including Flash, Processing, and more. We have the required electronics tools at the venue but your encouraged to make arrangements for purchasing the following kit: http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_… Students are also encouraged to bring additional hardware and/or tools they are interested in working with. Bring DMX lighting, LEDs, projectors, etc. to experiment with real-time lighting control. Bring servos or motor controllers to experiment with motion. Bring accelerometers, rotary sensors; flex sensors, etc. to experiment with sensing motion. Bring basic architecture model making supplies to build a model to work with. We also recommend that you bring any electronics equipment you may have including a soldering iron and solder, wire strippers, helping hands, digital multimeter, etc. Materials required: Bring your own laptop. Software: Pd-extended (http://puredata.info/downloads) and Arduino (http://arduino.cc ), both free software, download and install before arriving, we can help troubleshoot any problems that arise. Available Seats: 12 students/ Cost: $150 Skills required: Location: NYC Resistor, 87 3rd Ave, 4th Floor, Brooklyn, NY, nycresistor.com http://puredata.info/docs/workshops/AcadiaSensorsInteraction _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

readanysf_duration_speed
by oskoff lovich 17 Oct '10

17 Oct '10

Hi list, I am using the audio player readanysf~ from August Black and i have some question: for the last outlet we have (samplerate, lenght in seconds, and others..) the length in seconds of the player is related to speed=1 if i change the speed for example speed=0.20 obsviously the length of the file played is going to be more big.. how much ? how can i calculate the new lenght in seconds for a 44100 audio file? this speed means 20% of 44100 samples per second? any help is welcome!! best, oscar -- >>>http://noconventions.mobi/noish

Hello listees I'd like to know if there is a way to act on pd objects via a script language, I mean, coding behaviors and feedbacks? Sorry if this sounds noob, my knowledge about pd is very basic. Thanks, C

[PD-announce] NYC Patching Circle this Sunday 10/17, 3-8pm
by Hans-Christoph Steiner 15 Oct '10

15 Oct '10

Time for more patching! 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 NYC Resistor this Sunday from 3-8pm. 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. Every third Sunday of the month, so this Sunday, August 15th! 3-8pm (a little later than before) Free! Directions ---------- Patching Circle, http://puredata.info/community/NYCPatchingCircle NYC Resistor, http://www.nycresistor.com/ Sunday, Oct 17th, 3-8pm 87 3rd Avenue, (between Bergen and Dean), 4th Floor Brooklyn, NY 11217 Tel. +1.347.850.4872 (Hans) or +1.347.586.9270 (NYCR) 2/3/4/5/B/D/Q/N/R to Atlantic/Pacific LIRR to Atlantic Terminal F/G to Bergen _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

web update of pd-extended
by patrick 15 Oct '10

15 Oct '10

hi hans & all, i am working on a small software with wxwidgets and came across a solution for updating the package, the software or the updater via http. it's cross platform and very flexible to my eyes. i am just proposing this solution for pd-extended, that way people who wants to upgrade, just need to launch the "web update" (listing the externals that are new, updated, documentation etc...). http://wxcode.sourceforge.net/docs/webupdate/ i am sure there's other open source solution out there. pat
