Abstract
The electronic musical instrument provides an internal memory for storing performance data corresponding to a musical performance played by using a keyboard thereof and an external memory which can be freely attached to and detached from the main body thereof. The performance data stored in the internal memory can be normally transferred to and stored in the external memory. However, in the case where data quantity of the performance data stored in the internal memory is larger than a storage capacity of the external memory, the performance data stored in the internal memory are controlled to be inhibited from being transferred to the external memory. In this case, an alarm may be generated in order to inform a player of data quantity of the performance data to be overflowed from the external memory when such performance data are to be stored in the external memory.
