a composition of mine made with pd
by Libero Mureddu 17 Jul '07

17 Jul '07

Hi, I finally edited the video part for a composition that I made last september-october with pd and the yamaha disklavier. Thanks to Derek Holzer that helped me during a pd workshop in Helsinki to realize a first version of the piece. Video is here (youtube embedded in the page): www.myspace.com/liberomureddu Info about the composition here: http://webusers.siba.fi/~limuredd/deploration.html Enjoy! I have also a question: originally the piece had also an animation made with gem. Do you know how to export as a video file a gem animation? Best regards, Libero -- Libero Mureddu Vanha Viertotie, 21 as 417 00350 Helsinki Finland http://webusers.siba.fi/~limuredd/ http://www.myspace.com/liberomureddu

Can't use standard C libraries on external compilation for windows using MINGW
by Isidro Gonzalez 16 Jul '07

16 Jul '07

Hello: I followed Alberto Zin's instructions for compiling pd externals using Mingw and they worked OK. But: I modified de hello.c code adding the opening and closing of a file. Of course, the <stdio.h> header file must be added to the code. Attached to this message is the modified "hello.c". The code compiles Ok, and I get the hello.o using the following command line: C:\pd\isidro\hello>gcc -c hello.c -o hello.o But when I try to link to get the Dll file, I get the following message: C:\pd\isidro\hello>ld -export_dynamic -shared -o hello.dll hello.o c:/pd/bin/pd.dll hello.o(.text+0x16):hello.c: undefined reference to `fopen' hello.o(.text+0x30):hello.c: undefined reference to `fclose' The same I get if I use some Standard Library Function like <string.h> or other... Maybe I am doing something really stupid but if you know what's up it will save lots of time to me...

PD on PS3
by Christopher Murtagh 16 Jul '07

16 Jul '07

Greetings folks, Has anyone tried to run PD on a PS3 with any success? I'm going to give it a whirl in the next month or so and I'd rather contribute to an effort rather than re-invent the wheel. I'm a longtime Max/MSP user and a big FLOSS fan. I've been wanting to try PD for quite some time, but haven't had a free moment to do so. Should I get my hands wet with PD on more traditional hardware first? The PS3 only has 256MB of RAM, which can be pretty limiting, but one of my clients is a company that develops a popular distro for PPC and PS3. So, any things I need to do to get PD to work on the PS3, I'm going to try to get into the distro as well. Cheers, Chris

Poll: Ctrl-click to toggle editmode
by Hans-Christoph Steiner 16 Jul '07

16 Jul '07

Hey all, I just quickly banged out a little hack to make Cmd-Click toggle editmode on the Mac. This is how it works on Max/MSP and it's a handy shortcut. It would be trivial for me to add this to Windows and GNU/Linux using Ctrl-Click. Yes or no? What do you think? Any potential problems? (I know on Mac OS X, Ctrl-Click is mapped to right-click so that you can get the properties/help menu using a one button mouse). .hc ------------------------------------------------------------------------ ---- Mistrust authority - promote decentralization. - the hacker ethic

LABoral Centre for Art and Industrial Creation LABworkshops Call for participation Free Tools for Creators Whether for ethical, economical or technical reasons more and more digital artists are using, or interested in using, free software in their work. This is despite the serious lack of specific training in the field. LABoral in collaboration with Hangar, proposes a series of workshops for all artists interested in learning to work with free software. Hangar is a visual arts production centre from Barcelona and has over five years experience working with free software in a creative environment. Taken together, the three workshops provide a complete toolkit for the artist wanting to working with interactive audiovisual environments. VIDEO: RECORD, GENERATE, PERFORM This workshop will focus on the creation of programmes for the use of real time video-VJing, installations and interactive video. Participants will learn how to capture video and prepare loops using Kino, and to manipulate them in real time with Pure Data (PD). The generation of 3D visuals will also be taught. Pure Data (PD) is a real-time graphical programming environment for audio, video, and graphical processing. It is one of the most flexible tools available for creators working with real-time media. PD runs on Linux, OSX and Windows. The workshop is for beginners as well as experienced users. Workshop led by: Lluis GomeZ I Bigorda is a coder and responsible for free software in Hangar, Barcelona. He has led PD workshops in Spain, Brazil, Palestine and France. http://artefacte.org/pd/ Lituz (Carles Lopez) is an audiovisual performer. He has been playing video internationally.

In addition, the workshop will cover interaction with audio, based on methods like pitch tracking and beat detection. Participants will learn to create programmes (patches) for audio generation and performance using Pure Data (PD), a real-time graphical programming environment for audio, video, and graphical processing. They will also learn the basics of the audio studio in Linux – multitrack recording and mixing using Ardour and Rosegarden. These are robust free alternatives to commercial programmes such as ProTools. The workshop is for beginners as well as experienced users. Workshop led by : Yves Degoyon.

It is based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of the language used by Wiring, while the Arduino environment is based on Processing. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other outputs. Arduino projects can stand alone, or communicate with software running on your computer (e.g. Flash, Processing, Pure Data). The boards can be assembled by hand or purchased preassembled; the open-source IDE can be downloaded for free. Arduino received an Honorary Mention in the Digital Communities section of the 2006 Prix Ars Electronica. The workshop is for beginners as well as experienced users. Workshop led by: David Cuartielles is co-creator of the Arduino Open Hardware Platform and has directed numerous workshops. He exhibits his own artistic work regularly.

Sorry, forgot to paste the subject line in previous posting of this mail. (I'm in digest mode) On Wed, 27 Jun 2007, Alberto Zin wrote: > is there a list of papers/talks that will be presened at PD convention 2007 > somewhere ? The review period have just finished. What's left is basically to put results together, compensate for missing reviews, etc. There have been 43 submissions, so, most of the papers will be accepted. I'm not the supervisor of reviews so I can't tell you more. btw, don't forget also Piksel 2007 in Bergen in Norway/November: https://www.bek.no/pipermail/piksel/2007-May/002803.html _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal QC Canada
