In order to deal with a large amount of data and achieve a high-speed data transfer, an electronic musical instrument employs the configuration providing with plural CPUs and one main memory (RAM) so that the memory is accessed by plural CPUs. Herein, each of the CPUs provides a specific data bus, so that each of them can receive and transfer data via the specific data bus. When performing a data transfer between each CPU and memory, a line connection is selectively established between the memory and selected one of the data buses, so that each CPU can easily perform a data transfer by accessing the memory via its data bus.
