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.

Regnskog Bergen 2010 from macumbista on Vimeo.

Regnskog is a contemporary re-interpretation of David Tudor’s series of compositions from the 1970’s entitled Rainforest. It uses various types of sonic transducers to play live sounds through the assortment of resonant metal objects suspended by wires in the performance space. Additionally, an 8×8 matrix mixer allows the sound from any of the objects to be sent to any of the performers, making the whole piece an experiment in generative chaos.

The structure of the piece is improvisational, shifting between relatively static installation-like moments and performative sections where the artists seek new relationships with the objects and each other. The audience is free to move around the performance space, engage in conversations and explore the resonant objects, thus adding new life to the rainforest.

The performers: Harald Fetveit (Oslo), Gisle Frøysland (Bergen), Derek Holzer (Berlin), Ryan Jordan (London), Jørgen Knudsen (Bergen), Signe Lidèn (Bergen), Julien Ottavi (Nantes), Jørgen Træen (Bergen)

Produced 10-16 October 2010 in Bergen, Norway by Piksel.no. Video by Derek Holzer and Elisabeth Nesheim.

Reflections

After some years working in this experimental music scene, you realize that even if you put a bunch of performers in the same room and tell them they are working on the same thing, they all remain soloists at heart. Regnskog suffered initially as any group project might from egoistic hotdoggery, with some artists unable to look past the object in front of them as their own personal PA system. Once we got past that phase, things opened up quite a bit on the second night with many of us experimenting with the entire room as instrument and system, much as I originally intended. A small but highly engaged audience explored the room as well–listening, looking, touching and even singing with the pieces! It was a massive learning experience for me personally, which I hope to benefit from with the next two prospective versions of the project in Berlin and Tallinn during 2011. Details as soon as they are confirmed…

I’m currently waiting to see if Scandinavian Airlines can locate the suitcase containing my synthesizer, misplaced somewhere between Bergen, Norway and Aalborg, Denmark on Tuesday morning. After 36 hours a kind of delirium sets in, thinking about two and a half years of (uninsured) work floating around out there somewhere in the world.

Is it a sign I shouldn’t have brought such a precious thing out of the house? Or maybe just a sign I am traveling too much?

I saw quite a few lake-forest-and-mountain-view cabins around Norway that I wouldn’t have minded settling down in with that very synth, a pair of Genelec speakers, some tape to record onto and maybe a spare change of clothing for the next year or two. Someone please tell me how to follow those dreams!

Or at least tell me where my goddamned electronics are…

EDIT: SAS finally did tell me where my electronics are, and I should be reunited with them shortly as of morning of 21 Oct. Leaving this entry up as a snapshot of my mental processes…

REGNSKOG: a Collaborative Workshop/Performance/Installation in the Spirit of David Tudor
Produced by Piksel.no

INTRODUCTION: HANDS DIRTY ART

Over the past few years, a strong reaction against the sterile world of laptop sound and video has inspired a new interest in analog processes, or “hands dirty” art in the words of practitioner John Richards. With this renewed analog interest comes a fresh exploration of the pioneers of the electronic arts during the pre-digital era of the 1960s and 1970s. Artists and inventors such as Nam June Paik, Steina & Woody Vasulka, Don Buchla, Serge Tcherepnin, Dan Sandin and David Tudor all constructed their own unique instruments long before similar tools became commercially available or freely downloadable–and often through a long, rigorous process of self-education in electronics.

DAVID TUDOR’S RAINFOREST

David Tudor, in particular, has become the focus of intense interest (c.f. Leonardo Music Journal 14, 2004). His transformation from John Cage’s concert pianist to an electronic performer and autodidact engineer in his own right is archetypal for the contemporary media artist, who also must oscillate between the creative and the learning processes. His work Rainforest also stands out as an exemplary model of the collaborative process within a technically defined, yet socially open system.

Rainforest used a series of transducers to play prerecorded and live sounds through various resonant metal objects suspended by wires in the performance space. It was also conceived as a workshop, involving different musicians and artists in a collaborative setting, each contributing their own sounds, ideas and energies to the performances, which often lasted four or five hours! A complex mixer system allowed the sounds coming from one resonant object to be directed through another, spawning chaotic generations of new sound patterns. The sounds played could be heard through loudspeakers as well as the objects themselves, however they could also be physically felt by touching the objects. Tudor was especially interested in two audiences: children and the blind.

REGNSKOG

Regnskog is conceived as a contemporary re-interpretation of Rainforest as a workshop, performance and public installation. In the spirit of Tudor’s work, much of the equipment and materials will be built by the participants/performers themselves.
