。 At least a tempo register that can set the tempo using an external switch, and a tempo ROM that outputs a predetermined count value according to the output of the tempo register.
, a tempo counter whose count value is determined according to the output of the tempo ROM, a display device, and a sound generating means that controls the sound when the tempo counter finishes counting, and the tempo register is configured to operate in response to a push button of the external switch. The tempo counter is configured to have both an increment operation for each increment operation and an automatic increment operation by continuing to press an external switch, and is configured to restart the tempo counter for each increment operation, thereby making the tempo cycle accurate after the increment operation. electronic metronome.
