ELECTRONIC MUSICAL INSTRUMENT EMPLOYING VARIABLE RESISTOR FINGERBOARDS

摘要

An electronic musical instrument wherein there are several performing units. These performing units are made up of variable resistor fingerboards and variable frequency oscillators acting as tone generators. These oscillators are connected to the respective contact units which determine the frequencies of these oscillators. Tone signals are generated when one or more fingers simultaneously depress the performing units at points on the fingerboards. The relationship between the pressure contact unit and the variable frequency oscillators is so determined as to make the frequencies of the generated tone signals correspond to those of notes which are harmonized into a single chord. By continuously varying the point of finger contact it is possible to produce monophonic chord and portamento signals and to vary the coloring and volume of the musical tone signals on each of them or combinations of them.
