SCALE SOUND GENERATOR CIRCUIT DISPOSITION

摘要

A circuit arrangement for generating the tones of a tonal scale includes a master oscillator and a number of sets of frequency converters. The output signals of each set of frequency converters forms each of the tones of an octave. A frequency shifter is connected between at least one selected set of frequency converters and the master oscillator in order to shift the frequency supplied to the selected set of frequency converters from the master oscillator to cause a desired shift in the frequency of each of the tones of the octave produced by the selected set of frequency converters.
