This is the first Recording from an ETC session in September 1982. It appeared on a couple of my compilations of short works at the time: Green River Blues, Lonesome Blues and Video Haiku.
This used a basic sync control patch where fake horizontal and or vertical sync pulses are synthesized and then fed to a black and white video camera(s) of the day, which were timed with external V and H sync pulses. This patch included a colorized waveform mix being sequenced with the same through the Cat frame buffer and then keyed with the negative camera image. This is a real time recording, not post, no editing.
