Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument for separately recording a musical piece into performance data and non-performance data.

[0002]

2. Description of the Related Art Conventionally, when a musical composition is composed of performance data such as pitch, volume and timing, and non-performance data (series data) such as tone color number and style, performance data and non-performance data. An electronic musical instrument (automatic performance device) has been proposed in which the musical composition is separately recorded and reproduced, and the musical composition is reproduced by reproducing the musical composition from the automatic musical composition data based on the non-commercial musical data (Patent Publication 4). -69
396).

[0003]

However, in the above-mentioned conventional electronic musical instrument, although the performance data and the non-performance data are separately recorded, when the music is reproduced, the performance data is reproduced based on the non-performance data. Therefore, the non-performance data and the performance data must always be combined and recorded.

Therefore, when the non-performance data is not so important in the music, for example, only the performance data may be recorded and the non-performance data set by the panel operation may be used. The non-performance data had to be recorded together with the performance data. In today's electronic musical instruments, the data capacity of non-performance data is very large. Therefore, recording such non-performance data causes a pressure on the storage capacity of the storage medium, which is not preferable. Absent.

Also, depending on the music, it may be sufficient to share the non-performance data that has already been recorded. On the other hand, on the contrary, there are cases where it is desired to freely combine the non-performance data to give a desired effect to the music. In the conventional electronic musical instrument, since the non-performance data must be recorded in combination with the performance data as described above, even if the non-performance data that can be shared like the former is already recorded, the same non-performance data is not recorded. Data must be recorded in duplicate, which puts pressure on the storage capacity of the storage medium.On the other hand, when you want to give a desired effect to a song like the latter, you are bound by the recorded non-performance data. , The free creativity of the performer will be impaired.

In order to solve the above-mentioned problems, it is necessary to separately record the performance data and the non-performance data and configure the electronic musical instrument so that the performance data or the non-performance data can be loaded as needed. Good.

However, in an electronic musical instrument configured to simply record the performance data and the non-performance data separately, when the music is played by combining the performance data and the non-performance data, which non-performance data is recorded. The player must remember which performance data should be combined with the performance data (or vice versa), and must actually load non-performance data or performance data and try it. . With the former player's own method of remembering,
This is inconvenient when another player plays the combination set by such a player, and the latter method of loading and testing has a problem that the player has to find a combination that he or she thinks is good.

The present invention has been made in view of the above problems, and improves the operability of the performer by a simple procedure, does not impair the creativity of the performer, and does not impair non-performance data and duplicate non-performance. An object of the present invention is to provide an electronic musical instrument capable of reducing the storage capacity of a recording medium by not recording performance data and thereby reducing the cost.

[0009]

In order to achieve the above object, the present invention provides a separate recording means for separating music into performance data and non-performance data and recording them in a storage means, and the performance data and non-performance data. When one of the data is recorded in the storage means, instruction information recording means for recording the instruction information for instructing the other data related to the one data together with the one data, and the player performing the instruction. It is characterized by having a selecting means capable of selecting whether or not to record the information together with the one data.

Further, preferably, when one of the performance data and the non-performance data separately stored in the storage means is read out, when the instruction information is also recorded in the read data. Is a search / presentation unit for searching the other data related to the read data according to the instruction information, and presenting the other related data to the performer, and selectively reading the presented other data. And a reading means.

[0011]

According to the structure of the present invention, when one of the performance data and the non-performance data is recorded in the storage means, the performer selects the association between the one data and the other data. In this case, the instruction information for instructing the other data is recorded together with the one data.

Further, when one of the performance data and the non-performance data separately stored in the storage means is read, if the instruction information is also recorded in the read data, The other data related to the read data is searched according to the instruction information and presented to the performer, and the presented related data is selective (when the performer does not select any of the presented related data). Including).

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

As shown in the figure, the disk stores a plurality of files (for example, the parameter file and the song file of FIG. 4), the position of each file on the disk, and the free space of the disk. 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 configured 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 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 response to the reproduction of a song or the input of a song, a tone generation process for producing a musical tone is performed (step S2), and the operation state of the operation panel switch 1 is changed. 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 a 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 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 has been completed, this load processing is terminated, 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 the data has been completed because the free space of the disc is small and the file may be recorded over a plurality of discs. . 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 the convenience of explanation, it is indispensable for explaining the present invention. All but the ones are omitted.

FIG. 8 is a flow chart 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, 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, after executing a related song designation processing subroutine which will be described later with reference to FIG. 10 (step S22), the storage parameter selection screen of FIG. 3 is displayed on the display 5 (step S23), and the cursor key is pressed. Move the data input cursor according to the operation (step S2
4) The data at the cursor position is changed according to the operation of the data input key (step S25). That is, by the processes of steps S24 and S25, the above-mentioned storage parameters are selected, and information indicating which parameters have been selected is temporarily stored in the work area of the RAM 5.

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 capacity. 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 the storage medium of the save destination is a hard disk in the determination of step S30, the display screen described with reference to 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 on 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.) are stored in the data shown 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 selects "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.

FIG. 10 is a flow chart showing the detailed procedure of the related song designation processing subroutine of step S22 of FIG.

In the figure, first, a list of songs that the performer can currently select is displayed on the display 5 (step S61).

Next, it is judged whether or not the performer has designated a song from the list of songs (step S62), and when designated, the song name is temporarily stored in the work area of the RAM 4 (step S63). On the other hand, when the song is not designated, nothing is done and the related song designation process ends.

As described above, this processing is for storing the song name in the associated song name area of the parameter file when it is necessary to associate the parameter file to be saved on the disk with the already input song. Pre-processing, that is, processing for storing the song name in the work area of the RAM 4 is performed.

FIG. 11 is a flow chart showing the procedure of song selection processing. In this processing, when the performer selects a song and plays it back, the parameter file associated with that song can also be selected. It is a thing. This process is called, for example, when a song selection switch (not shown) of the operation panel switch 1 is pressed. That is, this is one of the panel processes in step S3 of FIG.

In FIG. 11, first, the data of the song designated by the performer is prepared (step S71). Here, the preparation means, for example, when a performer specifies a song by inputting the song name, data corresponding to the song name is stored in a storage medium (in the present embodiment, the floppy disk). A process of reading from a disk or a hard disk) and storing it in a predetermined area of the RAM 4.

Next, the parameter files stored in the floppy disk or hard disk are searched one by one, and the contents of the related song areas in each file are sequentially read out, which corresponds to the song name designated by the performer in step S71. A parameter file to be used is selected, and a list of the selected parameter files is displayed on the display 5 (step S72).

Next, it is judged from the list of parameter files whether or not the performer has designated a file (step S73). When the performer has designated the file,
The parameter file is read from the disc, and a loading process is performed to rewrite the parameter currently set by the read parameter (step S7).
4) The reproduction of the song is started (step S75).

On the other hand, if it is determined in step S73 that the performer has not designated a parameter file, that is, if the currently set parameters are acceptable,
The step S74 is skipped and the process proceeds to the step S75.

As described above, in the electronic musical instrument of this embodiment, the song and the parameters are separated and recorded on the disc, and there is a parameter associated with the song (that is, a parameter file recorded on the disc). In this case, the song name to be associated with the related song name area in the parameter file is stored, and when the song is played, the parameter file related to the song can be searched and selected. The parameter file can be managed according to whether or not the song name is stored in. For example, in the case of a song whose parameters are not important, if the song name is not stored in the related song name area and the parameter file is not recorded on the disc, the disc capacity can be reduced. Further, when the same parameter file is used for a plurality of songs, only one parameter file needs to be stored on the disc by storing the same song name in the related song name area of the parameter file. The disk capacity can be reduced.

Further, in the present embodiment, when the song is played back, a list of parameter files associated with the song is displayed, so that which song is associated with which parameter file is performed by the performer himself / herself. Does not need to be stored, and there is no need to actually load the parameter file into the RAM 4 and try it. Furthermore, by performing such a list display, the performer can use the parameter file created by another performer and associated with the song without difficulty.

The player can also choose not to specify the parameter file to be loaded from the list display,
In this case, the transfer time can be shortened and, in place of the associated parameter, the player can operate the operation panel switch 1 to freely combine and try the parameters. Can promote free creativity. In this way, the electronic musical instrument of this embodiment can further improve the operability of the player.

Although only one song can be associated with each parameter file in this embodiment, a plurality of songs may be associated with each other. If you can link multiple songs in this way,
The song already associated with the parameter file may not be selected by another parameter file, or may be selectable. In order to be able to associate a plurality of songs, it is necessary to increase the associated song name area of the parameter file according to the number of songs that can be associated.

Further, in this embodiment, the information of the song to be associated with the parameter file side is stored, but the present invention is not limited to this, and the information of the parameter file to be associated with the song side may be stored. In this embodiment, the song name is used as this information, but the information is not limited to this and may be any information that can identify each song.

[0073]

As described above, according to the present invention,
When one of the performance data and the non-performance data is recorded in the storage means, if the performer selects the association between the one data and the other data, the other data is designated. Since the instruction information is recorded together with the one data, it is not necessary to record the same data redundantly, the storage area of the storage means can be saved, and the cost can be reduced by reducing the storage capacity. Has the effect of enabling.

When one of the performance data and the non-performance data separately stored in the storage means is read, if the instruction information is also recorded in the read data, The other data related to the read data is retrieved according to the instruction information and presented to the performer, and the presented related data is selectively read out. Therefore, the performer himself / herself stores the relevance of the data. You can select the required data without the need.
Furthermore, when reading some of the associated data, if some of the data is unnecessary, it is possible to choose not to perform the read, so that it is possible to shorten the time for reading the unnecessary data and to Instead of, you can try various combinations of data that the performer inputs at hand.
