Vector Synthesis Workshop Berlin 5-7 JUL 2019

Posted in Announcement on May 23rd, 2019 by admin

The Vector Synthesis workshop investigates the direct relationship between sound+image. It draws inspiration from media archaeology and obsolete technologies such as the Cathode Ray Tube monitor, combined with contemporary laser display techniques. Participants will learn how to draw Lissajous figures, render simple two- and three-dimensional shapes, and process photographs and video into vector artwork which can be displayed on oscilloscopes, Vectrex consoles, and ILDA laser displays using audio signals which can also be heard. These vector shapes can also be further modified in real time using external audio sources such as voice, amplified instruments, or electronic synthesizers provided by the participants.


You can see examples of what you might do here:

The core of the workshop will be examples written in the Pure Data programming language. Detailed instructions on how to install and set up Pure Data, as well as a software oscilloscope emulator so you can see your work without special hardware, will be sent to registered participants.

You can view the Vector Synthesis code here:

The language of this workshop is English. Participants are required to bring their own laptops with software installed according to pre-event instructions sent by email.

DURATION
This is one continuous workshop of three days, 5 hours per day. Participation on individual days is not possible.
—FRI 05 JULY 12-17:00
—SAT 06 JULY 12-17:00
—SUN 07 JULY 12-17:00
—Max participants: 14 (50% will be students from Humboldt University, so 7 tickets are available for outside participants)

LOCATION
Signallabor, Humboldt University of Berlin, Georgenstraße 47, Raum 2.26 (2nd floor), Berlin Germany

With kind thanks to Dr. Stefan Höltgen, the Signallabor, and Humboldt University for their generous sponsorship of the event location.

Macumbista Benjolin V5

Posted in Announcement on May 4th, 2019 by admin

Dear friends: I am about to start a building run of a dozen new Macumbista Benjolin V5 instruments, to be completed in July/August 2019. Features listed below. If you would like to order one of these instruments, please send an email to MACUMBISTA at the domain GMAIL dot COM with the subject line “Benjolin V5” for further info.

The Benjolin is a standalone synthesizer containing two oscillators (one LFO and one VCO), a voltage controlled lowpass filter (VCF), and a circuit called a “Rungler”, which allows chaotic cross-modulation possibilities between the different parts of the circuit. They have been further customized with a patchbay, which can be used to interface with other modular synthesizers or to setup further feedback systems within the Benjolin itself, as well as external audio inputs to the Benjolin filters, two “loop” modes, and an external input to drive the Rungler clock.

The Benjolin V5 features a newly-designed PCB with a few improvements, namely that it can be powered from normal 12V DC wall supplies rather than the more exotic 12V AC supplies I used earlier.

Available box finishes are “hammered metal” green, gray, and blue paint, as well as a “natural” finish. Some examples of colors here:

http://macumbista.net/wp-content/uploads/2015/07/start-feb-benjos.jpg

The price of the Benjolin V4 is EUR 565 (incl. 19% EU VAT) / EUR 475 (for customers outside the EU), plus shipping costs. All my instruments are made-to-order, and require a 50% deposit to begin work (EUR 240). I accept IBAN bank transfers and PayPal (with 4% PayPal fee added).

Vector Synthesis Workshop Piksel

Posted in Announcement on December 28th, 2017 by admin

Derek Holzer, Vector Synthesis workshop
Building: Piksel Studio 207, Bergen NO
Dates: 9-11 March 2018
Time: tba

All workshops are free entrance. To sign up send an email to:
prod(at)piksel(dot)no

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.

Vector Synthesis Library for Pure Data

Posted in Announcement on August 4th, 2017 by admin

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.

You can see a demo video of the scan processing and 3D rotation functions here:

And you can see a two hour video presentation of this library here:
