Frequency divider for tone source apparatus for Arabian scale in electronic organ

摘要

A frequency divider for a tone source for an Arabian scale in an electronic organ of the type wherein musical tone signals for a standard musical scale, musical tone signals higher than the same by 50 cents and musical tone signals lower than the same by 50 cents can be obtained from the output signal of a main oscillator. The output signal of the main oscillator is frequency-divided by at least one frequency divider to obtain an output signal. The aforesaid frequency divider comprises a counter and an AND circuit. An input terminal of the frequency divider is connected through the counter to an input terminal on one side of the AND circuit and is connected directly to an input terminal on the other side of the AND circuit.
