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:

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.

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.

ATELIER MACUMBA presents

A NIGHT of PRIMITIVE ELECTRONICS featuring

GROWTH [DE]
RANDOM SONIC ATTACK [PL/GR/DE]
DEREK HOLZER + HÉLÈNE CANUET [USA/FR/DE]
The Students of SONIC COLLEGE HADERSLEV [DK]

plus DISTILLED SPIRITS by SLOWLANDS

17 AUG 2016 20:00 doors, 20:30 sound
55 Herzbergstrasse, Berlin-Lichtenberg

Event is held in the ground floor “cold hall”, next to the former Canteen.

GROWTH is a forest of ambiguities. It is an inward gaze, a state of being, and a largely improvised performance by the hands of Berlin based non-musician Lars Ennsen which may be classified in terms of minimal, ambient, and drone.

RANDOM SONIC ATTACK landed on planet earth approximately half a year ago. A collaboration between Goolyk & Damn Jar. Cassette tape album is in the processing state. In the meantime you can listen to one studio improvisation and one live recording here:
https://soundcloud.com/randomsonicattack

HÉLÈNE CANUET is a polymorphe French photographer, writer and performer. Rare on the art scene over 4 years , her work was only show in few galeries in Berlin. Lyrical, surrealistic or conceptuel her propositions are always very personal, almost intimate on the edge of poesie and social politic. Based on improvisation some of her projects seems done to snaked emotion and fired expectation.

For her collaboration with instrument-builder DEREK HOLZER this evening, Hélène will present her spoken-word texts as material for the DELILAH TOO VOICE ENCODING SYSTEM.

Due to some studies at the Media Lab of Aalto University in Helsinki, I will be on hiatus for a while. Therefore:

I am no longer accepting any bookings for workshops or concerts until January 2017.

I am no longer accepting any instrument orders until June 2017, and even then my production line maybe undergo some changes.

Thank you for all your support as friends, customers and admirers over the last few years. It’s been a great ride. Watch this space or my more-frequently-updated Facebook page for updates: www.facebook.com/macumbistanet

PROJECT SPACE KLEINER SALON, BERLIN DE
2-3 APRIL 2016

Explore DIY electronics and sound art performance with your own SoundBox during this two-day workshop in Berlin-Kreuzberg.

SoundBoxes are small, primitive electro-acoustic instruments built from a wooden box, a speaker, a small audio amplifier and a contact microphone. They can create a variety of drone and reverb-type sounds through feedback between the speaker and microphone, or they can bring out the hidden sounds found within everyday objects. They also have small touchpoints which can be used to produce a variety of “circuit bending” sounds.

During the first day, we will learn about electricity, how it becomes sound and then how to build the SoundBoxes themselves. On the second day, we will explore the possibilities of the SoundBoxes, with the goal of collaboratively creating a score for a sound performance of approximately 10-15 minutes in length.

This workshop does not require any previous knowledge of electronics, only an interest and a curiosity in both sound and instrument-building.
