SYNCHRONATOR   device     nov 2009
The SYNCHRONATOR device transforms your audio into a composite video signal, compatible with all video equipment supporting composite video input.
With 3 audio inputs and 1 video out, the SYNCHRONATOR device enables you to visualize your sounds on each of the primary color channels of the video signal. It adds video sync pulses and color coding signals to your audio, effectively disguising the input as a composite video signal. The device is powered with a 6V adapter and features a color/b&w switch as its only on-board controller. Other manipulations are done solely with the audio input.
The device was officially released on November 10 2010, at the Netherlands Institute for Media Arts.
The first edition of the SYNCHRONATOR device was limited to 100 numbered units, which were sold out by october 2010.
It was shipped in a box with DVD, manual, 6V adapter (european only) and composite video cable.


SYNCHRONATOR   manual     oct 2009
A manual to accompany the release of the SYNCHRONATOR device.


SYNCHRONATOR   DVD     jul 2009
The first SYNCHRONATOR DVD was released on the Cavity label in july 2009.
Included are the 2006 SYNCHRONATOR video and nine new tracks. Original recordings were produced with the SYNCHRONATOR device for PAL video by Bas van Koolwijk and Gert-Jan Prins.
Although especially adapted versions of all tracks are included for flat screen monitor, to properly experience the DVD it should be viewed on a CRT television monitor.
The release has been made possible thanks to our individual support from Fonds BKVB and Nederlands Fonds voor Podiumkunsten.

FDBCK/AV   installation     jun 2008
jun 12 - 29 2008, FDBCK/AV installation, 'De Nieuwe Salon' exhibition, Utrecht NL


10K PFFA   interface     apr 2008
Software application for the conversion of visual to audible data for the project '10.000 Peacock Feathers in Foaming Acid' by Evelina Domnitch and Dmitry Gelfand.
Laser light is used to scan the ever-shifting surfaces of nucleating and dissipating soap bubble clusters. When refracted at specific angles, this penetrating light generates a reticulate, large-scale projection of normally invisible salty acid formations, and exposes their underlying electro-chemical forces.
Through analysis of the projected shapes and movements by use of video digitisation, the visual information is transposed to audio in order to create a realtime soundtrack.

SYNCHRONATOR   'Impakt Works' residency     apr-jun 2006
Since the early years of video art, works have been made which do not actually produce a standard TV signal waveform and therefore cannot be directly recorded. Some are based primarily upon magnetic distortion of the normal TV scan pattern, others utilise a Cathode Ray Tube as if it were an oscilloscope screen.
SYNCHRONATOR is a video and audio research project by Gert-Jan Prins and Bas van Koolwijk in an attempt to make use of the characteristic visual qualities of such techniques, whilst tackling the problems concerning recordability of the signal with a combination of current digital and analogue means. Visit for more information.
Part of the project is a dual screen performance of which a first try out was presented on June 3 2006, during an evening filled with hardware oriented audiovisual arts. Works by the Vasulkas, reMI, Evelina Domnitch & Dmitry Gelfand in collaboration with Asmus Tietchens, were included in the programme.
A video production as part of the SYNCHRONATOR project will be released in August 2006.
The project was commissioned by Impakt and was being developed as part of an 'Impakt Works' residency.


As part of the Impakt residency, a three-day workshop about developing an AV performance.
Analogue and digital techniques were examined to create a direct interaction between image and sound. The working method was mainly practical. Facets such as the use of interfaces, videotronics, video/audio software and improvisation in electronic music were examined.
Your instructors: Gert-Jan Prins, Bas van Koolwijk and Karl Klomp.

FDBCK/AV - Silver 3D     mar 2006
A stereographic version of the video 'FDBCK/AV - Silver'. Viewed with anaglyph red/cyan glasses, the illusion of depth is added to the otherwise two dimensional video pictures. This version is part of the Staalplaat Soundsystem installation 'The Ultrasound of Therapy'.

2006 I.D.E.A.L. Festival, Nantes FR

Vertical Helical Scan I     jan 2006
The video describes the gradual decomposition of the video signal on VHS tape when repetitively copied. With every generation, the analogue information looses quality. Some parts of it disappear, other information is spontaneously added by the equipment. Eventually the signal is rendered unreadable as it gets dissolved into the medium.
A 'homage' to the Video Home System. Commissioned by Planetart

FDBCK/AV - Red Flag     oct 2005
Red Flag is an abstract video, produced with software applications that were developed for the live performance FDBCK/AV. The 'flagging' seen in this video is of a digital nature entirely, but its logic is based on analogue video processing. The same logic applies to the computations by which FDBCK/AV creates a feedback control circuit between audio and video signals. Behind its technical appearance, the video addresses the issue of aesthetic contemplation of form versus the more worldly agenda of utility and politics.

UBIK    sep 2004
Installation responsive to a monumental building. Synchronised sound, smoke and light neutralise a historical space. Inspired by Philip K. Dick's 'Ubik' [1969]. With Christian Toonk and Ronald Nijhof for the SKOL 2004 exhibition in Utrecht.

Urban[ISM]     jun 2004
An installation for the Impakt event and exhibition 'Yarning Utrecht' at the BAK Gallery in Utrecht. Urban[ism] was a collaboration with Christian Toonk and Ryan Parteka.
As people travel through space, points between destinations are often neglected. In their multi-channel audio and video installation, Umatic members have transferred this in between volume of the urban space to the gallery space. Nestled between two walls is a space for one to consider what lay in between.

Maps~ / Psychonavigators     jun 2004
Maps~ is a video application for a collaborative performance that came about after a conjunction of ideas for the Impakt event 'Yarning Utrecht'.
Simular to roadmaps being abstractions of the world as we percieve it, soundscapes reflect a view of the space around us. The intricate use of layering in both the video and the audio of this project, makes image and sound seamlessly connect.
Performed at BAK Gallery, June 18 2004, with Derek Holzer and Christian Toonk.

European Data Cup   mar 2004
Presentation about a generative parasite project turning the European Football Championships into an electronic music generator. With Christian Toonk and Ronald Nijhof.
Presented at BAK Gallery, Utrecht.

RGB   mar 2004
The live performance RGB is based on the video channels red, green and blue. By direct transposition of the video signal to audio, Bas van Koolwijk creates a real time soundtrack using colour fields only. The sound environment is completed by Christian Toonk. Toonk uses audio feedback derived from amplified internal computer processes.
RGB is a minimal technoid environment, built up using the basics of video signal with sound.

OZONE   sep 2003
An installation exploring the shifting tide of signals, frequencies and codes passing through our bodies every day. The installation is based around a four-channel, generative digital video, displayed on four television sets. Four 100m loops of copper wire serve as antennas, receiving the Very Low Frequencies [VLF] emitted by the television tubes. The resulting signals are converted into digital audio, which is returned to further influence the video, creating a self-sustaining feedback loop.
Ozone is a collaboration with Derek Holzer, following a residence at Medienturm, Graz.
Presented during the 'Steirische Herbst' Art Festival in Graz, Austria [september/october 2003], the European Media Art Festival in Osnabrück, Germany [april/may 2004] and the WAVES exhibition in Riga LV [aug/sep 2006]
