ABSTRACT:
An electronic musical instrument which is capable of attaining the tonal coloration and "feeling" of an acoustic instrument and wherein the pitch, timbre, and loudness of each sound which is produced can be controlled by the performer in real time in an accurate and repeatable manner as the instrument is being played. The instrument is comprised of a plurality of string-like members which simulate the strings of an acoustic instrument and wherein sounds of varying pitch are produced by depressing the strings against a fingerboard at different positions along their lengths. An audio oscillator means is associated with each string-like member for producing a frequency-controllable audio output signal, and means responsive to a control signal for varying the overtone content and amplitude of the audio output signal is provided. In order to generate the control signal, means accessible to the performer and capable of being moved to different control positions in an accurate and repeatable manner is utilized. In the preferred embodiment, such means includes a light source and photoresponsive means, and a translatable means having an aperture for controlling the amount of light which is incident on the photoresponsive means.
