It also stores a file management table that stores the position and capacity of each file, and manages each file based on these information.

CPU of electronic musical instrument constructed as described above
The control process executed by the control unit 2 will be described below with reference to the flowcharts of FIGS.

FIG. 6 is a flow chart 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 response to song reproduction and song input, and tone generation processing for producing musical tones is performed (step S2) to change the operation state of the operation panel switch 1. It monitors and detects a switch whose operation state has changed, and performs panel processing such as parameter setting processing corresponding to the switch (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 apparatus is operating, an automatic accompaniment process is performed (step S5), and other processes other than the above-described process are performed (step S6), and then the process returns to step S2 to perform the above-described process. repeat.

FIG. 7 is a flow chart showing the procedure of a loading 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 performer presses a load switch (not shown), for example. That is, this is one of the panel processes in step S3 of FIG.

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

Next, when the performer selects a desired file from the displayed dialog, the file is read out from the floppy disk or hard disk, and the parameter stored in the file is used to rewrite the parameter in the predetermined register ( In step S12), it is determined whether reading of all data has been completed (step S13).

When it is determined in step S13 that the reading of all data is completed, the load processing is completed, while
If reading of all data has not been completed yet, the player is requested to replace the disc (step S1).
4) When the performer replaces the disc according to the request, the process proceeds to step S12, and the subsequent parameters are read from the disc and the parameters are rewritten.
Hereinafter, similar processing is repeated.

In step S13, it is determined whether or not the reading of all data has been completed because the free space of the disk is small and the 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, so if the file stored in the hard disk is read in this loading process, step S13 is performed.
This load processing is immediately terminated without performing the determination of.

In this load process (not only this process, but also other processes described later), it is necessary to actually perform various error processes, but for convenience of explanation, it is essential when explaining the present invention. All but the ones are omitted.

FIG. 8 is a flowchart showing the procedure of a save process for saving the currently set parameters as a file in the floppy disk or hard disk. This process is also called by the player pressing, for example, a save switch (not shown), as in the load process of FIG. 7, so that step S3 of FIG.
This is a process in the panel setting process.

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 processing in step S21, that is, the preparation processing for creating the parameter file in the data storage format described with reference to FIG. 4 is performed in the work area of the RAM 4, for example.

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

Next, the storage parameter selection screen of FIG. 3 is displayed on the display 5 (step S23), the data input cursor is moved according to the operation of the cursor key (step S24), and the operation of the data input key is performed. The data at the cursor position is changed according to (step S2
5). That is, by the processing of steps S24 and S25, the above-described selection of the storage parameter is performed, and the 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 the storage parameter selection processing is terminated, and the EX
When the ECUTE switch is not pressed, the process returns to step S23 to continue the storage parameter selection processing,
On the other hand, when the EXECUTE switch is pressed, R
After calculating the capacity of all the data to be saved based on the information of the storage parameter 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 disk space. Here, the free space of the disk is obtained by reading the information stored in the file management table of FIG.

Next, it is judged from the result of this comparison whether or not the free disk space is insufficient (step S2).
8) If there is sufficient free space on the disk, after executing the data transfer processing subroutine of FIG. 9 to be described later (step S29), this save processing is terminated, while if there is insufficient free space, Determines whether the storage medium of 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 in FIG. 2 is displayed on the display 5, and only [Reduce data] can be selected ( Step S3
1). At this time, for example, other [Swap disk] or [Auto split] may not be displayed, or the characters may be displayed with faint characters so that other than [Reduce data] cannot be selected. .

When the performer presses the switch corresponding to [reduce data], the process proceeds to step S32.
An example of the parameter reduction of which parameter can be saved from the currently selected parameter to save the free space according to the insufficient data capacity is displayed.
, And this save processing subroutine is called again to execute the save parameter selection processing and the like (step S
33) After this, this save processing ends.

On the other hand, if it is determined in step S30 that the save destination storage medium is not a hard disk, that is, a floppy disk, the display screen of FIG. 2, that is, [reduce data], [replace disk],
[Auto division] is displayed on the display 5 and the player is allowed to select. As mentioned above, a switch is provided for each option so that the performer can select one of [Reduce data], [Replace disk], and [Auto split]. Are numbered "1", "2", and "3" from the top in FIG. Then, when the performer selects a desired option by pressing the 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 performer is stored in the RAM 4
It is determined by inspecting the number stored in the work area (step S35), and when the number is "1", that is, when the performer selects "reduce data", the process proceeds to step S32, as described above. The same processing as that in the hard disk is executed.

When the number stored in the work area of the RAM 4 is "2" in the determination in step S35, that is, when the performer selects "swap disks",
"2" is stored in a predetermined area tmode (hereinafter, this content is referred to as "transfer mode tmode") for storing the transfer mode secured in the work area of the RAM 4 (step S3).
6) After confirming that the player has exchanged the discs, the save is started (step S37), the same data transfer processing subroutine as in step S29 is executed (step S38), and then the save processing is ended. .

Further, in the determination of step S35, the RAM
When the number stored in the work area 4 is "3", that is, when the performer 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), this save processing ends.

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

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

Next, it is determined whether or not the disk has a free area (step S52). Specifically, this determination is made by constantly monitoring the free area 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 is completed (step S53). If the file transfer is not completed, the process returns to step S51 to transfer the parameter file. On the other hand, when the file transfer is completed, the file management table is corrected, that is, the file name of the transferred file, the position on the disk, and the like are registered in the file management table (step S54). The transfer process ends.

When it is determined in step S52 that there is no free space on the disc, it is determined whether the transfer mode tmode is "3", that is, whether the performer 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, when it is determined in step S55 that the transfer mode tmode is not "3", that is, when the performer does not select "automatic division", the display 5
Is displayed to the effect that the save has failed (step S57),
Then, the process proceeds to step S54.

As described above, in the present embodiment, when the parameters selected by the performer are recorded on the disk which is the storage medium, if the total data capacity of the parameters exceeds the free capacity of the disk, Various recording methods that the performer can adopt according to the type of disc are presented, and the performer can select from among them, so the performer should make an appropriate recording according to the free space. The contents can be selected and combined, and a method other than the method of deleting and recording the data can be selected. As a result, the range of selection of recording methods is widened, and the recording method desired by the performer can be selected.

[0059]

As described above, according to the present invention,
When a plurality of parameters selected by the performer 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 capacity detected by the detection means, the transfer and storage is performed. Since the player is instructed to select a plurality of parameters to be reproduced again, the player has the effect of being able to select and transfer and store the desired parameters.

Further, when the plurality of parameters selected by the performer 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 capacity detected by the detection means, Since a plurality of means that the performer can take are presented to the performer, the performer can select a storage method according to the situation. Therefore, the performer can select and combine appropriate contents to be recorded according to the free space, and can select a method other than the method of deleting and recording data.
