At the time of recording, after the SMF format including the items of the first music information S ₁ , the second music information S ₂ , the third music information S ₃ ... Nth music information S _n is recorded, F _{1 to} F _m are recorded.
Each file is recorded, and the file designation information corresponding to the file is recorded from S ₁ to
It is recorded corresponding to any number information of S _n . For example, if you record song 1 file F ₁ ,
The file designation information for designating is recorded corresponding to the first music piece information S ₁ .

When a desired song file is recorded and then the file is erased, the song number corresponding to the erased file becomes empty, as shown for example with respect to the third song information S ₃ . Moreover, as shown with respect to the n-th music information, the unregistered music number is also empty. If the number of song files for one disc is set to m, the maximum song number n is m or less (n ≤ m)
Becomes

The file designation information for each number information includes song file name data SFN, song name data SN, created model name data MN, etc., as representatively shown for the first song information S ₁ . Here, the data MN is
It represents the model name of the electronic musical instrument or personal computer used for recording the files SMF, F _{1 to} F _m .

Some models used for recording do not have a file management function. In such a model,
Although it is possible to record a song file, it is not possible to record the file SMF as described above.

The song management information in the file SMF is displayed by the display DPL as shown in FIG. Therefore, the user can select a desired song (song file) by looking at the displayed contents. Then, the selected music piece can be automatically played and data can be edited.

The key operation detection circuit 12 detects key operation information by scanning a large number of key switches on the keyboard 12A.

The switch operation detection circuit 14 detects switch operation information by scanning a large number of switches in the switch group 14A. The switch group 14A includes a load switch LDS, a save switch SVS, a yes instruction switch, a no instruction switch, and the like as switches related to the implementation of the present invention.

The CPU 16 executes various processes for tone generation and file management according to the program stored in the ROM 18, and these processes will be described later with reference to FIGS.

The RAM 20 includes a storage area used as a register or the like for various processes by the CPU 16, and is also used to store various information read from the FD mounted on the FD drive device 22.

The FD drive device 22 is placed in the F position at a predetermined position.
D is removable, CPU1 when FD is attached
Recording or reproduction operation is possible under the control of 6. FD
As an example, the drive device 22 includes a song management file SMF and song files F ₁ to F ₁ as shown in FIG.
An FD that records _m and F _x is attached. When a desired song file is selected from this FD and read out to the RAM 20,
The automatic performance can be performed based on the automatic performance information in the song file.

The display circuit 24 is the display unit DP shown in FIG.
It has L and is designed to display the song management information in the file SMF on this display.

The tone generator circuit 26 has a plurality of tone forming channels and can generate tone signals for each channel. Key operation information is supplied from the key operation detection circuit 12 to the tone generator circuit 26, and a manual performance sound signal can be generated. Also, the sound source circuit 2
The pitch designation information and the like read out from the RAM 20 as the performance progresses is supplied to 6 so that an automatic performance sound signal can be generated.

The tone signal from the tone generator circuit 26 is supplied to a sound system 28 including an output amplifier, a speaker and the like, and converted into sound.

FIG. 2 shows a subroutine of the load switch (LDS) ON process. FD shown in FIG.
Switch LD with the FD drive device 22 attached
When S is turned on, the routine of FIG. 2 is started. In the FD of FIG. 4, the files SMF and F _{1 to} F _m are the same as those described above with reference to FIG. 7, and the file F _x is recorded with a model that does not have a file management function as described above with reference to FIG. 8. Is.

In step 30, the file SMF is stored in the FD.
Determine if there is If the result of this determination is affirmative (Y), the process moves to step 32 and the song management information in the SMF is set to R.
Read in a predetermined area in the AM 20.

Next, in step 34, it is checked whether or not the song file managed by SMF is actually in the FD. Then, in step 36, it is determined whether or not the song file is insufficient. If the result of this determination is affirmative (Y), the process moves to step 38 and the file shortage is indicated by the DPL.
To display a warning. Then, in step 40, the management information of the missing file is deleted from the song management information in the RAM 20. This is because there is no need to manage song files that have not been recorded.

When the determination result of step 36 is negative (N) or when the process of step 40 is completed, the process proceeds to step 42. In step 42, it is checked whether or not there is a file not managed by SMF in the FD. Then, in step 44, it is determined whether or not there is an unmanaged file. If the determination result is negative (N), it means that all song files in the FD are managed by SMF, and the process proceeds to step 46.

At step 46, the display DPL has a RAM.
The management information in 20 is displayed. As an example, the file designation information for designating the song 4 is recorded as the third song information S ₃ in the SMF, but the file of the song 4 is FD.
If it is not recorded in, the file designation information designating the song 4 is erased in steps 36 to 40,
The third song information S ₃ is an empty song number. In this case, if the n-th piece of music information S _n is also an empty piece number, the display DPL shows
Song management information similar to that shown in FIG. 7 is displayed.
After step 46, the process returns to the main routine (not shown).

If the determination result of step 44 is affirmative (Y), the process proceeds to step 48. As mentioned above, F
If the file F _x is recorded in D, step 4
The determination result of 4 is affirmative (Y), and the file F _x becomes an unmanaged file.

In step 48, the extension of the file name given to the unmanaged file F _x is checked. And
Proceeds to step 50, the extension of F _x is (or can be processed by the apparatus data F _x) it matches the extension allowed by (file management apparatus in an electronic musical instrument) the apparatus determines. If the determination result is negative (N), the process proceeds to step 52.

At step 52, the header data of the unmanaged file F _x is read into the RAM 20. Then, in step 54, whether the header data format matches the data format allowed by this device (whether the data of F _x can be processed by this device)
judge. The reason why the data processing can be performed doubly in this way is to deal with the case where the extension is not added.

In the determination of step 54, as an example, if the data sequences are the same, it is determined that they are of the same format. In addition, the standard MIDI (Musical Instrument
In the case of a Digital Interface) file, if the chunk name matches “MThd” (header chunk name),
It is determined that the formats are the same.

If the determination result of step 50 or 54 is affirmative (Y), it means that the data processing was possible, and the routine proceeds to step 56. In step 56, the file designation information as shown in S ₁ of FIG. 7 is created as the management information regarding the non-management file F _x , and is temporarily registered in the empty song number in the song management information in the RAM 20. As an example,
If the song management information in the RAM 20 is the one shown in the DPL of FIG. 7, the management information regarding F _x is the third song information S ₃
Write in the position.

If the result of the determination in step 54 is negative (N), it means that the data cannot be processed, and the process proceeds to step 58 without passing through step 56. Also, when the process of step 56 is completed, the process proceeds to step 58.

In step 58, it is determined whether or not there are any other unmanaged files. If the determination result is affirmative (Y), the process returns to step 48, and the subsequent processes are repeated as described above.

If the result of the determination in step 58 is negative (N), it means that the data processing is not possible and the management information has not been created, or that the data processing is possible and the temporary registration of the management information is completed. Move on to. At step 46, the song management information in the RAM 20 is displayed on the display DPL in the same manner as described above.

As described above, when the song management information in the RAM 20 is the same as the DPL shown in FIG. 7, if the management information is not created, the display DPL will display the DP shown in FIG.
The display content is the same as L. If the management information is temporarily registered at the position of the third music information S ₃ , the display DPL
Has the display contents as shown in the DPL of FIG.

By the way, when the determination result of step 30 is negative (N), it means that there is no SMF, and the process proceeds to step 60. This is a case where only one or more song files such as F _x are recorded in the FD. In step 60, the SMF format is created in the same manner as described above and written in a predetermined area in the RAM 20. Then, the process proceeds to step 48, and the subsequent processes are repeated as described above. As a result, if data processing is possible, management information is created for each song file. Then, the created management information is provisionally registered in the RAM 20 and displayed on the display DPL together with the management information recorded in the FD.

FIG. 3 shows a subroutine for the save switch (SVS) on process. This routine is started when the switch SVS is turned on.

At step 70, the song management information in the RAM 20 is written in the FD. When the temporary registration is performed in step 56 in FIG. 2, the song management information including the management information related to the temporary registration is displayed in the SFD shown in FIG.
Written in. The FD used for saving may be the FD shown in FIG. 4 or a new FD. In the case of the FD shown in FIG. 4, the third music information S corresponding to the contents displayed on the display DPL is displayed.
The vacant information at the position of ₃ is updated by the management information of the song X (file designation information that designates the file of the song X).

Next, at step 72, it is judged whether or not the song file is added or modified. As mentioned above, LDS
After executing the on processing subroutine, select the desired song file and correct the data in the file,
You can add new song files based on your manual performance.

If the result of the determination at step 72 is affirmative (Y), it means that the song file has been added or modified, and at step 74 the added or modified song file is written to the FD. When a song file is added, the management information of the additional file is added to the song management information in the RAM 20 when the file is added, so the song management information including this added management information is stored in step 7.
It is written to FD with 0. When using a new FD, all song files can be written to the FD in step 74 by reading all the data of the FD of FIG. 4 into the RAM 20 and then starting the routine of FIG.

When the determination result of step 72 is negative (N) or when the process of step 74 is completed, the process returns to the main routine.

According to the above-described embodiment, the management information is created for the song file such as F _x having no management information and displayed on the display DPL, so that the file selection can be performed easily and accurately. it can. Further, since the same management information as that displayed is recorded in the FD, the same management information as the previous time can be displayed when the FD is used next time, and file selection can be performed easily and accurately. . Furthermore, since it is automatically determined whether or not data processing is possible, it is not necessary for the user to make a determination.

FIG. 5 shows a first modification of the routine of FIG. In this example, the portion from P to Q in FIG. 2 is replaced by steps 80 to 84.

In step 80, a registerable file name such as the file F _x is displayed on the display device DPL. Then, in step 82, it is determined whether registration is OK. As an example, let the display DPL display the phrase "Registration OK?"
Yes (Y) or no (N) is instructed by the yes instruction switch or the no instruction switch in the switch group 14A.

If the determination result in step 82 is affirmative (Y), the process proceeds to step 84, management information is created in the same manner as in step 56 described above, and is temporarily registered in an empty song number in the song management information in RAM 20. To do.

When the determination result of step 82 is negative (N) or when the process of step 84 ends, the process proceeds to step 58 of FIG.

According to the routine of FIG. 5, there is an advantage that the user can arbitrarily select whether or not to create / register the management information.

FIG. 6 shows a second modification of the routine shown in FIG. In this example, step 90 is added after step 58 in FIG. 2, and in step 90, the song management information in the RAM 20 is written in the FD in the same manner as step 70 in FIG.

According to the routine of FIG. 6, the management information can be automatically written in the FD at the time of loading, and the save switch SVS does not need to be turned on.

The present invention is not limited to the above embodiments, but can be implemented in various modified forms. For example, the following modifications (1) to (7) are possible.

(1) The data file to be managed is not limited to a song data file, but a file of automatic accompaniment style data (pattern data for each style such as rock, waltz, etc.) and a tone parameter data file such as a tone color. Any kind of file may be used, such as a file of tone control data such as volume and effect related to panel setting.

(2) The recording medium is not limited to the floppy disk, but may be a hard disk, a magneto-optical disk or the like.

(3) Although the music number is managed by the management file, the music number is not limited to the numeral and may be managed by a code such as A, B, C ...

(4) Although the created management information is automatically registered in the empty number, the number to be registered may be designated in advance or may be changed after registration.

(5) When creating the management information, the management information may include information indicating that the data file related to the management information is recorded in another device.

(6) The routine of FIG. 2 may be started by detecting that the recording medium is mounted at a predetermined position, instead of being started in response to the ON operation of the load switch LDS.
