DELAY LINE MEMORY
The sounds being generated with this instrument are visualised as blocks of pixels. As these enter the 2-dimensional delay line they reveal patterns that are not always recognisable through hearing alone.
Performed solo or extended with drums.

SYNCHRONATOR
Since the early years of video art, works have been made which do not produce a standard TV signal waveform and therefore cannot be directly recorded or projected with current equipment.
For SYNCHRONATOR, Bas van Koolwijk and Gert-Jan Prins have created their own hardware to overcome these limitations.
Their SYNCHRONATOR device transforms audio into a composite video signal, compatible with all video equipment supporting composite video input.   synchronator.com

SYNCHRONATOR is a dual screen performance of which a first try-out was presented on June 3 2006.
Since then it was performed at venues and festivals such as: Avanto [Helsinki], Melkweg [Amsterdam], Club Transmediale [Berlin], Donau Festival [Krems].

Additionally a SYNCHRONATOR orchestra was formed in 2012 with participation of: Justin Bennett, Robin Fox, Jérôme Noetinger, Billy Roisz, Tina Frank, Bas van Koolwijk, Gert-Jan Prins.

FDBCK/AV
Solo live performance in which Van Koolwijk generates a feedback control circuit between the audio and the video signals, making audio and video become two facets of a self-sustaining data stream. External control is established by manipulation of parameters for the interpretation of image>sound and sound>image. The application with which this is done, makes no use of camera or movie input. All sound and image data are generated real-time within the feedback system using digital video basics.

Over the years, the software was improved and adapted many times.
In 2013 a version was created especially for projection within the domes of the Sphaerae project.

Previous FDBCK/AV performances include Mutek 05 [Montréal], Club Transmediale [Berlin], Garage Festival [Stralsund] and Videologia [Moscow, Volgograd]

RF
The short and loud brother in the family of FDBCK/AV live sets. RF stands for 'Red Flag'.
Flagging or flagwaving is a video term refering to the sideways pulling and fluttering seen at the top of a TV picture caused by a skew misadjustment or some other tape tension error. Although the flagging in this work is of a digital nature entirely, its logic is based on these analogue video characteristics.
As a single screen video, 'FDBCK/AV - Red Flag' was released in october 2005.

SKIF++
The electronic audio-visual trio SKIF++ is a collaboration of Jeff Carey, Robert van Heumen and Bas van Koolwijk. The SKIF++ sound ranges from sonic bursts to melodic melancholy and back, using joysticks and selfmade controllers to keep it all in line (most of the time). All compositions and performances are improvised, but based on structures that give each piece its distinct character. west28.nl/SKIF++

RGB
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.
