We are very excited to publish the VectorHack Festival 2018 lineup today. I really feel like we have invited some of the most brilliant minds in the field of experimental, audiovisual vector graphics to Zagreb and Ljubljana for one week (01-07 OCT 2018) of hacking, presentations, keynote talks, workshops, and live performances.

In Zagreb, I will demonstrate my Vector Synthesis library for Pure Data on 02.10.18 and give the keynote lecture “A Media Archaeology of Vector Graphics” on 03.10.18, while in Ljubljana I will perform the Vector Synthesis set live on 05.10.18.

The Vector Hack participants:

Philip Baljeu / Jonas Bers / Stefanie Bräuer / Hrvoslava Brkušić / Ted Davis / Andrew Duff / Jerobeam Fenderson / Darko Fritz / Robert Henke / Ida Hiršenfelder / Derek Holzer / members of Kikimore (Staša Guček / Sara Mlakar / Nina Orlić / Barbara Poček) / Chris King / Vanda Kreutz / Roland Lioni / Ivan Marušić Klif / Alberto Novell / Douglas Nunn / Hansi Raber / Bernhard Rasinger / Joost Rekveld

I do hope some of you will join us, all talks, keynotes, and performances are free to enter.

I am pleased to announce that I’ve been invited to present Vector Synthesis on 29 August at the Pori Art Museum, Pori FI in the context of the exhibition Steina & Woody Vasulka: Art of Memory, Works from 1969 to 2000. I will be giving a guided tour of the exhibition and performing with my Rutt-Etra/Vasulka inspired scan processing system.

And this week, I will perform at a live cinema event focused on the work of ASTEPBACK (Andrea Saggiomo and Gaëlle Cavalieri) and Marek Pluciennik at the Myymälä2 gallery, Helsinki FI.

I would be so very pleased to see some of you at either event.

16 & 17 Jun 2018, 11:00 — 17:00
Location: Kuusi Palaa, Kolmas linja 7, 00530 Helsinki, Finland

During this two-day workshop, you will explore the direct relationship between sound and image.

Using the Pure Data programming environment, you can directly control the vertical and horizontal movements, as well as the brightness, of a beam of light. You will then investigate Lissajous figures, 3D models, Rutt-Etra video scan processing, and other audio-driven visual shapes and forms which can be displayed and manipulated in real time on an XY oscilloscope, or with oscilloscope emulating software directly on your laptop.

The participation fee for this workshop is EUR 50, with a 10% discount for Kuusi Palaa members. The workshop runs from 11:00 to 17:00 each day.

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:

http://macumbista.net/?page_id=5000

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.

https://github.com/macumbista/vectorsynthesis

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.

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.

You can see the latest version of the code here:

https://github.com/macumbista/vectorsynthesis

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.

The technique is based on the well-known principle of Lissajous figures, which are a mathematical representation of complex harmonic motion. Originally displayed by reflecting light between mirrors attached to a pair of vibrating tuning forks, we are most used to seeing them on the screen of an oscilloscope, where they can be produced using pairs of electronic oscillators tuned to specific ratios.

There is a wealth of such experiments from the 1950s onward by major figure such as Mary Ellen Bute, John Whitney, Larry Cuba, Manfred Mohr, Nam June Paik, Ben Laposky, Bill Etra, and Steina & Woody Vasulka, which were all highly inspiration to the development of this library.

DESCRIPTION

The VECTOR SYNTHESIS project 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.

SOFTWARE

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 using a DC coupled soundcard.

HARDWARE

We will also discuss hardware essentials such as how to modify a normal CRT monitor for vector inputs, how to hack together a cheap DC coupled soundcard, how to use a microcontroller such as the Teensy, Bela or Axoloti as a base for your vector synthesizer, and how to interface with the International Laser Display Association control protocol.

WHAT TO BRING

Please bring your own laptop. If you have a DC soundcard such as the MOTU Ultralight, please bring that as well. Many cheap USB soundcards can be adapted for DC use as well, you can find them on EBay or I will bring several for sale at the workshop. There will be a limited number of displays, so if you already own an analog XY oscilloscope, Vectrex game console, or other vector monitor, that would be very useful to bring. And finally, please get in touch if you have a CRT monitor you would like to see hacked (no guarantees!) during the hardware phase of the workshop. (Additional materials fee applies, we can discuss this.)

ABOUT THE WORKSHOP HOLDER

Derek Holzer is an American instrument builder and sound artist whose current interests include DIY analogue electronics, field recording, media archaeology and the meeting points of electroacoustic, noise, improv and extreme music.

The Benjolin is a standalone synthesizer designed by Rob Hordijk from the Netherlands in 2009 and available as an open hardware project online. This Pure Data implementation of the Benjolin was coded by Derek Holzer in SEP-NOV 2016 in Helsinki, after several years of producing customized hardware Benjolins from his Berlin studio.
