FIG. 4 is a diagram showing an example of the data storage format of a certain parameter file stored in the floppy disk and the hard disk. The figure shows the parameters of FIG. 3 selected by the player to be stored. An example of a parameter file is shown.

In FIG. 4, the parameter file includes a management data area, a related song name (RELATED SONG NAME) area, and an area in which parameters selected by the player to be stored among the various parameters are stored (hereinafter referred to as “storage parameter area”). "). The management data area stores data such as the file name of the file and the capacity of the entire file. The related song name area stores the file name of the song associated with this file, that is, the song that uses the parameters of this file. In the storage parameter area, the parameters selected in FIG. 3, ie, setup data, pad data, panel registration data (panel registration data of numbers 1, 6, 9 and 14), custom style data (number 2,
5, 8, 16, 17, 22, 30, and 31) and custom voice data (custom voice data of numbers 1 to 4) are stored.

FIG. 5 is a view showing a storage image in the disk when a plurality of files are stored in the floppy disk or the hard disk.

As shown in the figure, the disk stores a plurality of files (for example, the parameter file and the song file shown in FIG. 4), the position of each file on the disk, and the free space of the disk. And a file management table for managing each file based on the information.

The CPU of the electronic musical instrument configured as described above
2 will be described below with reference to the flowcharts of FIGS.

FIG. 6 is a flowchart showing the procedure of the main routine. First, various initialization processes such as clearing the RAM 4 and resetting various ports are performed (step S1).

Next, event data and the like are output to the musical tone synthesizing circuit 8 in accordance with the reproduction of the song or the input of the song, a tone generation process for generating a musical tone is performed (step S2), and the operation state of the operation panel switch 1 is changed. Monitoring is performed to detect a switch whose operation state has changed, and panel processing such as parameter setting processing corresponding to the switch is performed (step S3).

Next, an automatic performance recording / reproducing process for recording and reproducing a song (automatic performance data) is performed (step S).
4) If the automatic accompaniment device is operated, an automatic accompaniment process is performed (step S5), and after performing other processes other than the above-described processes (step S6), the process returns to the step S2, and the above-described process is performed. repeat.

FIG. 7 is a flowchart showing the procedure of a load process for loading the contents of the parameter file stored in the floppy disk or hard disk into a predetermined register (register for setting various parameters) of the RAM 4. This process is called when the player presses, for example, a load switch (not shown). That is, this is one process during the panel process of step S3 in FIG.

In FIG. 7, first, it is determined whether or not a file to be loaded is specified, and if not, a dialog is displayed (step S11).

Next, when the player selects a desired file from the displayed dialogue, the file is read out from the floppy disk or hard disk, and the parameter in the predetermined register is rewritten with the parameter stored in the file ( Step S12), it is determined whether or not reading of all data has been completed (step S13).

When it is determined in step S13 that the reading of all the data has been completed, the loading process is terminated.
If the reading of all the data has not been completed yet, the player is requested to change the disc (step S1).
4) When the player changes the disk according to the request, the process proceeds to step S12, where the subsequent parameters are read from the disk and the parameters are rewritten.
Hereinafter, the same processing is repeated.

The reason why it is determined in step S13 whether or not reading of all data has been completed is because the free space of the disk is small and a file may be recorded over a plurality of disks. . In the present embodiment, the hard disk is assumed to be a non-replaceable recording medium. Therefore, when reading out a file stored in the hard disk in this load processing, the process proceeds to step S13.
, And immediately terminates the load processing.

In the present load process (not only the present process, but also other processes to be described later), it is actually necessary to perform various error processes. However, for the sake of explanation, it is indispensable to explain the present invention. Everything except those that are not shown is omitted.

FIG. 8 is a flowchart showing the procedure of a save process for saving the currently set parameters as a file on the floppy disk or hard disk. This process is also called by the player pressing a save switch (not shown), for example, as in the loading process of FIG.
Is one of the panel setting processes.

In FIG. 8, first, when the performer specifies a transfer destination file name, the file name is temporarily stored in the work area of the RAM 4 (step S21). The process such as step S21, that is, the preparation process for creating the parameter file in the data storage format described with reference to FIG.

Next, if it is necessary to associate the parameter file to be saved with the already input song, the song file name specified by the player is stored in the RAM.
4 is temporarily stored in the work area (step S2).
2).

Next, the storage parameter selection screen shown in FIG. 3 is displayed on the display 5 (step S23), and the data input cursor is moved in accordance with the operation of the cursor key (step S24). (Step S2).
5). That is, by the processing of steps S24 and S25, the above-described storage parameters are selected, and information indicating which parameter is selected is stored in the RAM.
5 is temporarily stored in the work area.

In the following step S26, an EX (not shown)
It is determined whether or not the ECUTE switch has been pressed, that is, whether or not to end the storage parameter selection processing.
When the ECUTE switch is not depressed, the process returns to step S23 to continue the selection process of the storage parameter,
On the other hand, when the EXECUTE switch is pressed, R
After calculating the capacity of all data to be saved based on the information of the storage parameters stored in the work area of AM4 (that is, the information stored in the work area in steps S21 to S25), the process proceeds to step S27.

In step S27, the calculated data capacity is compared with the free capacity of the disk. Here, the free space of the disk is obtained by reading the information stored in the file management table of FIG.

Next, it is determined whether or not the free space of the disk is insufficient based on the comparison result (step S2).
8) If there is enough free space on the disk, the save process is terminated after executing the data transfer process subroutine of FIG. 9 described later (step S29), and if the free space is insufficient. Determines whether the storage medium at the save destination is a hard disk (step S30).

If it is determined in step S30 that the storage medium of the save destination is a hard disk, the display screen described with reference to FIG. 2 is displayed on the display 5 so that only "reduce data" can be selected ( Step S3
1). At this time, for example, other [Replace Disc] or [Automatic Split] may not be displayed, or may be displayed with faint characters, so that other than [Reduce Data] may not be selected. .

When the player presses the switch corresponding to [decrease data], the process proceeds to step S32,
The display 5 shows an example of parameter reduction of which parameter should be reduced from the currently selected parameter to save within the free space according to the insufficient data capacity.
Is displayed, and this save processing subroutine is called again to perform the selection processing of the storage parameter again (step S
33) After that, this save processing ends.

On the other hand, if it is determined in step S30 that the storage medium of the save destination is not a hard disk, that is, if it is a floppy disk, the display screen of FIG. 2, ie, [reduce data], [swap disk],
[Automatic division] is displayed on the display 5 and the player selects it. As described above, a switch is provided for each option so that the player can select one of the options of [reduce data], [swap disc], and [automatic division]. Are numbered "1", "2" and "3" from the top in FIG. When the player selects a desired option by pressing a switch, the number corresponding to the option is stored in the RAM.
4 is stored in the work area (step S34).

Next, the result selected by the player is stored in the RAM 4
Is determined by inspecting the number stored in the work area (step S35), and when the number is "1", that is, when the player selects "reduce data", the process proceeds to step S32, and the above-described step S32 is performed. The same processing as the processing in the hard disk is executed.

If it is determined in step S35 that the number stored in the work area of the RAM 4 is "2", that is, if the player selects "change disc",
"2" is stored in a predetermined area tmode for storing the transfer mode secured in the work area of the RAM 4 (hereinafter, this content is referred to as "transfer mode tmode") (step S3).
6) After confirming that the player has replaced the disc, save is started (step S37), and a data transfer process subroutine similar to step S29 is executed (step S38), and then the save process is terminated. .

Further, in the determination in step S35, the RAM
When the number stored in the work area No. 4 is "3", that is, when the player selects [automatic division], the transfer mode tmode is set to "3" (step S3).
9) After executing the same data transfer processing subroutine as in step S29 (step S40), the save processing ends.

FIG. 9 is a flowchart showing a detailed procedure of the data transfer processing subroutine of steps S29, S38 and S40.

In the figure, first, based on the information about the storage parameters temporarily stored in the work area of the RAM 4, the data (selected parameters, transfer destination file name, related song name, etc.) is stored in the RAM 4 as shown in FIG. The file is transferred to the file created on the transfer destination disk while keeping the data storage format described in (1) (step S51).

Next, it is determined whether or not there is an empty area on the disk (step S52). Specifically, this determination is made by always monitoring the free space information of the disk stored in the file management table of FIG.

As a result of the determination in step S52, if there is a free area, it is determined whether or not the file transfer has been completed (step S53). If the file transfer has not been completed, the flow returns to step S51 to transfer the parameter file. On the other hand, when the transfer of the file is completed, the file management table is corrected, that is, the process of registering the file name and the position on the disk of the transferred file in the file management table is performed (step S54). The transfer process ends.

If it is determined in step S52 that there is no free space on the disk, it is determined whether or not the transfer mode tmode is "3", that is, whether or not the player has selected [automatic division]. When [Automatic division] is selected, the player is requested to replace the floppy disk (step S56), and then the process proceeds to step S53.

On the other hand, if it is determined in step S55 that the transfer mode tmode is not "3", that is, if the player has not selected [automatic division], the display 5
To indicate that the save failed (step S57),
Proceed to step S54.

As described above, in the present embodiment, when the parameters selected by the player are recorded on the disk as the storage medium, if the total data capacity of the parameters exceeds the free space of the disk, Various recording methods that can be adopted by the player according to the type of disc are presented, and the player can select from among them, so the player should record appropriately according to the free space. The contents can be selected and combined, and a method other than the method of deleting and recording data can be selected. Thereby, the range of selection of the recording method is expanded, and the recording method desired by the player can be selected.

[0059]

As described above, according to the present invention,
When the plurality of parameters selected by the player are transferred and stored in the second storage means, if the capacity of the plurality of parameters to be transferred and stored exceeds the free space detected by the detection means, the transfer storage is performed. Since the player is instructed to select a plurality of power parameters again, there is an effect that the player can select and transfer desired parameters.

When a plurality of parameters selected by the player are transferred and stored in the second storage means, if the capacity of the plurality of parameters to be transferred and stored exceeds the free space detected by the detection means, Since a plurality of means that the player can take are presented to the player, the player can select a storage method according to the situation. Therefore, the player can select and combine appropriate contents to be recorded in accordance with the free space, and can select a method other than the method of deleting and recording data.
