For our VJing we make use of our self-developed devices to let
the music directly control the flow of video. For this purpose an
audio-signal from the audio mixer is routed to our device and influences
the pictures in two ways: high-speed mixing and music dependent
pattern generating. The first effect (also described in the Hollywood
Machine) results in rhythmically confusing interference of two movie
The second effect is derived through multiplying and modulating
the audio signal onto the video. Patterns and lines in rhythmic
motion and transformation are embedded into the video.
Both ways of controlling video can be combined and are highly sensitive
to the music input either through direct modulation or with
the help of voltage controlled oscillators. In this way the machinery
can also be thought of as an analogue video synthesizer.
