Japanese Patent JPS5235293
Kind Code:
B1
Abstract:
A digital generator for producing from a single oscillator all the tones of a musical scale uses a number of serially connected tone converters, each producing an output tone one-half tone lower than the input tone applied to a particular converter. The converters are made up of a number of serially connected digital frequency dividers arranged in groups. Each group is connected to a logic gate. The logic gates are serially connected to an additional logic gate having an input connected to the input of the converter. At the output of the additional logic gate a tone will be produced that is either one-half tone or a whole tone lower than the frequency of the input tone to the converter.
