VECTOR SYNTHESIS WORKSHOP WITH DEREK HOLZER

VECTOR SYNTHESIS is an audiovisual, computational art project using sound synthesis and vector graphics display techniques to investigate the direct relationship between sound+image. It draws on the historical work of artists such as Mary Ellen Bute, John Whitney, Nam June Paik, Ben Laposky, and Steina & Woody Vasulka among many others, as well as on ideas of media archaeology and the creative re-use of obsolete technologies. Audio waveforms control the vertical and horizontal movements as well as the brightness of a single beam of light, tracing shapes, points and curves with a direct relationship between sound and image.
You can see several demo videos here:

SOFTWARE

The Vector Synthesis library allows the creation and manipulation of 2D and 3D vector shapes, Lissajous figures, and scan processed image and video inputs using audio signals sent directly to oscilloscopes, hacked CRT monitors, Vectrex game consoles, ILDA laser displays, or oscilloscope emulation softwares using the Pure Data programming environment.

During this workshop, you will learn how to use a custom library in the Pure Data programming environment to directly control the vertical and horizontal movements, as well as the brightness, of a beam of light. You will then explore Lissajous figures, waveform representations, and other multiplexed, audio-driven visual shapes and forms which can be displayed and manipulated in real time on an XY oscilloscope, Vectrex game console, ILDA laser display, and other analog vector displays, or with oscilloscope emulating software directly on your laptop.

ABOUT THE INSTRUCTOR

Derek Holzer (1972) is an American instrument builder and sound artist based in Helsinki FI & Berlin DE, whose current interests include DIY analog electronics, the relationship between sound + space, media archaeology and the meeting points of electroacoustic, noise, improv and extreme music. He has performed live, taught workshops and created scores of unique instruments and installations since 2002 across Europe, North and South America, and New Zealand

Some photo documentation from the Pure Data workshop held in Bergen during the Piksel10 festival. The workshop was held by Servando Barreiro and Arnfinn Killingtveit and was hosted by Piksel and TRAFO in collaboration. The audio is from the jam the last day of the workshop.

During the workshop, the students constructed simple software instruments and effects in pure data from scratch, were shown how to hack existing patches, learned about crude frequency analysis, explored the possibilities of video manipulation in pure data with GEM, made their own DIY reactable (without the projection), and learned about FM and AM synthesis, among other things.

after a week of intensive workshop in BALTAN  laboratories
a new version of OpenCV for PD has been released,
version 0.2-rc4 that fixes the following issues :

##########################
version 0.2-rc4 ( codename BALTANIK )

* fixed colorspace problems for mac ppc
* contours detection objects ( hu_compare and pgh_compare ) now give the posititon of matching contours.
* a folder of examples have been added, they should work with pd-extended.

##########################

you can find binaries for mac osx and linux packages on the wiki
as well as the source code ( for those who want to compile it ) here :

OpenLab 5 : Cafe OTO, 25th April 2009
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Openlab are providing a day of workshops & presentations about
opensource software, and performances in the evening at Cafe OTO,
Dalston. There is a venerable lineup of OpenLab members providing some
in depth knowledge during the day and some great performances at
night. The preliminary line up goes like this:

There are possibilities to participate in person by coming to one of the locations below, or remotely via the IRC interface built into the FLOSS Manuals editing interface. Video conferencing may take place between the
venues as well.

To participate, create a login at the PD FLOSS Manuals page:

New book by Johannes Kreidler now available online.

Abstract
Pd was initiated by American software engineer Miller Puckette, who previous co-developed the well known and similarly structured software Max/Msp. Pd is not commercial software; i.e., it was not developed by a corporation and is not for sale. Instead, it is “open source”: its source code is not the (patented) property of a corporation, but is rather freely available to all. One drawback to this is that a detailed operating manual for users who lack programming experience has not existed until now. In contrast to a corporation— which has a monetary interest in ensuring that first-time users can easily operate new software—the open source movement lacks such a driving force to make itself accessible. This book is an attempt to fill that gap.

This tutorial is designed for self-study, principally for composers. It begins with explanations of basic programming and acoustic principles then gradually builds up to the most advanced electronic music processing techniques. The book’s teaching approach is focused primarily on hearing, which we consider a faster and more enjoyable way to absorb new concepts than through abstract formulas.

The patches described are available for download.
