An automatic performance device is comprised of a memory for storing automatic performance data including event data, and a CPU which reads out the automatic performance data from the memory and plays back the automatic performance data for generating musical tones. A plurality of event data which overlap in output timing for generating musical tones are detected from the readout automatic performance data, and when the plurality of event data which overlap in output timing for generating musical tones are detected, the output timing of at least one of the plurality of event data is shifted.
