First, the table information in the first and second tables 2 and 3 in FIG. 3 will be described. In the figure, 1 and 0 indicate the necessity and non-necessity of the tone generation command, 1 being necessary and 0 being unnecessary. Further, the information in the table corresponds to the X axis and the Y axis, and in the present embodiment, the X axis has a value of 1 to 8, and the Y axis also has a value of 1 to 8. That is, now X = 2, Y = 3
The value is 1 in the first table 2 for the coordinates of, that is, a sounding command is required for the first sound source. Similarly, in the second table 3, the value becomes 0, which means that the tone generation command is unnecessary for the second sound source. As described above, it is determined based on the table information on the table whether or not a sound generation command is necessary for each sound source with respect to the input coordinates. Next, FIG. 4 will be described. FIG. 4 also shows the first and second tables 2 and 3 in FIG. Also in FIG. 4, 8 is the first table information and 9 is the second table information. The table in the case of FIG. 4 has as information only the upper and lower limit information of the range in which the sounding command is required on the X axis and the Y axis. In other words, the table described in FIG. 3 has a simplified form, and it is not possible to finely specify the pronunciation command at each coordinate on the table as in FIG. However, even a table based on information in the format as shown in FIG. 4 can constitute an electronic musical instrument for easily playing a plurality of sound sources, which is the object of the present invention.

Next, the assignment control unit 4 starts the operation of referring to the table based on the above-mentioned transmitted information. First, the address signal 7 identifies the addresses corresponding to the X and Y axes of the first and second tables 2 and 3. Next, the first and second tables 2 and 3 output the corresponding table information. 8 and 9 are table information, 8 is first table information, and 9 is second table information. Next, the assignment control unit 4 determines which sound source a sound generation command needs to be given based on the above table information, and sends the sound generation command to the necessary sound source. Now X = 2, Y
= 3 is input, the information of the first table is 1 and the information of the second table is 0, and a sounding command is required for the first sound source, the first sounding command 13 causes the first sound source to be generated. 5 is instructed to generate a tone, and the first tone signal 14 is output. Similarly, for the input coordinates, the pronunciation command of only the second sound source,
Two sounding commands, the first sound source and the second sound source, are issued.

As described above, in the embodiment of the present invention, with the above-described configuration, an electronic musical instrument in which a performer can easily play a plurality of sound sources can be realized.

Note that the format of the pronunciation information of the table is not particularly limited to the present invention as described in the embodiment of the present invention.
