Abstract

PURPOSE:To obtain a highest-octave-scale generator of simple circuit constitution for an electronic musical instrument by inputting the frequency division output of a longest-period feedback shift register to a 1/2 frequency divider and by using its output as a sound-source signal. CONSTITUTION:A main oscillation signal from an input 11 is passed through an inverter 12 to obtain an in-phase and an out-of-phase signal, driving a shift register 13. The output of an AND circuit 15 and an external reset 17 are inputted to an OR circuit 18, whose output sets the register 13 in response to a following clock. Consequently, the shift register is initialized when going to a prescribed final value set by the AND circuit 15, thereby dividing the frequency of the main oscillation signal 11 by an optional integer. The frequency division output which is the output of the AND circuit 15 is inputted to a 1/2 frequency divider 19 for frequency division, obtaining frequency division output 20-29 of respective stages. The 1/2 frequency divider 19 is reset with the external reset signal 17.
