For example, when the icon display is set by default, the icon information Ic corresponding to the genre information Gda (any of Gd1, Gd2, Gd3,...) In the accompanying information Ad is obtained from the icon correspondence table TB. In step S1, genre, time signature and composer are set as guide items for icon display based on user operation, and in the case of B setting in which priority is set in this order, the associated information is retrieved from the icon correspondence table TB. The icon information Ic to be displayed corresponding to the genre information, time signature information and composer information in Ad is obtained, and the icon size is determined according to the item priority of the icon to be displayed.

  In step S7, an icon is displayed based on the specified icon information Ic. For example, the content of the name information Nm in the accompanying information Ad is “012 Waltz for Debbie”, the content of the genre information in the accompanying information Ad is “Jazz Fusion”, and the content of the time signature information is “3”. / 4 ”and the music data (song data) Dm whose composer information is“ composer A ”is the default setting, as shown in the first column of FIG. : “012 Waltz for Debbie” and jazz fusion icon Ic1 are displayed as a set, and in the case of the B setting, as shown in the second column of FIG. 3 (2), the song title: “012 Waltz ・“For Debbie”, a large “jazz fusion” icon, a medium “3/4” icon, and a small “composer A” icon are displayed as a set.

  After the icon display process of S7, the process proceeds to step S8 to determine whether or not all music data (music data) has been processed. If all music data has not been processed (S8 = NO), step S3 is performed. Returning to step S4, the next music data is selected and the processes of steps S4 to S7 described above are performed. While all the music data is not processed (S8 = NO), the processes of steps S3 to S8 are repeated. When all the music data is processed (S8 = YES), the data name (song name) display area displayed on the screen display unit of the touch panel 17 is set to be operable by the user, and the user waits for the music data selection operation by the user. If there is, the process proceeds to step S9.

  In step S9, the user's selection operation is detected, and in the subsequent step S10, the music data (song data) detected by the selection operation is converted into a musical tone signal generation unit 9-10, or an automatic performance unit comprising CPU1, RAM2, ROM3, etc. Applies to 1-3. That is, in step S10, if the selected music data is song data, the music information Md in the music data Dm is acquired and stored in the automatic performance work area of the RAM 2 in order to automatically perform music later and generate music. To do. Then, the music data use process is terminated and the process returns to the original operation mode. In the normal operation mode, which is the original operation mode, musical tone generation processing is performed according to various user operations. That is, when the music data is processed in the music data use mode and the user performs an operation for starting the automatic performance in the original operation mode thereafter, the automatic performance section stores the music information stored in the automatic performance work area of the RAM 2. Based on Md (music data), it instructs the tone signal generator 9-10 to generate a tone.

  If the selected music data is a voice composed of waveform data and timbre parameters, the music information Md in the music data Dm is acquired in step S10. The parameters are stored in the memory, and various parameters are stored in various registers such as the tone generator circuit 9, the effect circuit 10, and the RAM 2. Thereafter, in the normal operation mode, the voice setting is reflected when the musical sound is generated. Similarly, for other types of music data, music information Md is stored in various registers and work areas, and used for music generation.
