ABSTRACT:
An electronic musical instrument is provided to produce audible tones by the use of at least a pair of electron beam guns having deflecting means, the output of the guns energizing luminous screens with masks in front of the screens of the tubes upon which is graphically depicted an image that represents one or more timbres or mixing control voltages. Electronic means are provided for energizing the cathode ray tubes so that they will scan the masks and light sensitive devices are focused on the images produced by the masks and a variety of means are used to mix the outputs.
