Abstract

The author describes a system for controlling an analog video processor (Sandin Image Processor) using an equal-tempered (musical) keyboard. The keyboard produces triads of D.C. voltages which control the levels of the red, green and blue components of various parts of the video image. This mode of control allows precise specification of video colors through a slightly modified form of music notation, which also makes possible the notation of time-variant progressions of color.
