Abstract
An automatic rhythm producing apparatus is capable of emphasizing a rhythm pattern of a desired percussion instrument among a plurality of rhythm patterns which constitute a rhythm. The rhythm producing apparatus has a pulse level control circuit for controlling the pulse level of a selected rhythm pattern signal among a plurality of rhythm pattern signals. This circuit is provided between a rhythm pattern forming circuit and a rhythm selection circuit. The apparatus also comprises control means for controlling the output of the rhythm selection circuit to prevent variation in the average level of the entire rhythm sound. Another example of the inventive apparatus further discloses means for controlling power voltage in a frequency dividing circuit.
