2. Description of the Related Art Conventionally, in an electronic musical instrument, performance information called pitch data or style data composed of, for example, timing data is stored in a memory, and automatic accompaniment is performed by reproducing the style data. There is. A plurality of types of such style data are prepared according to, for example, a genre (also referred to as a style) of a song, such as preset data in a ROM or data recorded on a disk (floppy disk or the like). Thus, automatic accompaniment according to a desired style can be performed.

When using style data recorded on a disc, a list of style data on the disc is displayed on a display, and all style data or a plurality of style data to be used are displayed to the user. The user selects the style data and loads the selected style data from the disk to the RAM in the main body of the electronic musical instrument by operating the load operation element after the selection operation is completed.

[0004]

In the conventional electronic musical instrument as described above, when style data in a disc is used, the style data is first selected, and further, a load operation is operated to change the style data in the disc. RAM
Since the playback of the style data (hereinafter referred to as "style playback") can be performed for the first time after the loading of the style data into the music data, the setting operation until the performance of the automatic accompaniment is performed is complicated and troublesome.

[0005] In a conventional electronic musical instrument, all the style data to be used is stored in the R on the main body before the style is reproduced.
It had to be loaded on the AM, which was not practical. For example, it is not possible to reproduce a style data that comes to mind while performing a performance, and there is a problem that various style reproductions cannot be enjoyed. If all the style data in the disc is loaded on the main unit, the style data can be changed as desired during style playback. In this case, most of the recording area in the RAM on the main unit is used. It will be used, which is not preferable for other processing.

SUMMARY OF THE INVENTION It is an object of the present invention to make it easy to set style data (performance information) from within a disc and to perform a variety of style reproductions while keeping the used recording area of the main body small.

When the performance information is instructed to be selected, the selected performance information is read from the performance information supply medium and written into the dedicated recording area in parallel with the reproduction process of the performance information being reproduced. And

[0008] According to the performance information setting apparatus of the first aspect, the writing means exclusively records the performance information of the performance information supply medium by performing a selection instruction operation on the performance information of the performance information supply medium. Since the process of writing to the area is started, there is no need to operate the load operator or the like, and the operation for setting performance information is simplified. The dedicated recording area of the storage means is for writing one piece of performance information.
Since it does not use a large storage area of storage means such as AM,
For example, the use recording area on the electronic musical instrument main body side can be reduced. In addition, during the reproduction of the performance information, when the performance information not written in the dedicated recording area is selected and instructed,

A section change switch 66 for performing a section change operation described later is provided.

FIG. 2 is a diagram showing a format of style data in the embodiment. One style data is given a style number, and a plurality of style data corresponding to a plurality of style numbers are stored in the external storage device 4.
(For example, a floppy disk). The style data preset in the ROM 2 has the same format. The style data of this embodiment is composed of section information corresponding to each section of intro, fill-in, main, and ending.

The "intro" is an accompaniment pattern to be inserted at the beginning of a song, the "fill-in" is an accompaniment pattern to be inserted at a bar or a link between passages, and the "main" is a basic pattern throughout a song. The accompaniment pattern for performing accompaniment, “ending”, is an accompaniment pattern inserted at the end of a song. Each section information is composed of section identification data, setting information, music information and end data,
The section identification data is data for identifying whether the data between the section identification data and the end data is an intro, fill-in, main, or ending section.

The setting information is recorded as a plurality of types of data for performing various settings relating to a sound source and various settings to be set on a main body panel when performing style reproduction for the section. By
Tones and effects are specified. The music information is event data for reproducing the music in the section in the order of progress of the music, and data of one or several measures in length is recorded. The music information of this embodiment includes event data such as note-on and note-off,

Further, each style data may include a chord progression corresponding to the style, and information representing a chord root and a chord type is recorded in the chord progression data according to the progress of the performance. The information indicating the chord root and chord type is data for converting the pitch between the information for the bass performance and the information for the chord performance during the style reproduction. Further, the chord progression data is one for each style.
In some cases, one section is recorded for each section information in the style.

FIG. 3 is a diagram conceptually showing the processing of the embodiment. The RAM 3 is set with a direct area A capable of storing one style data and a read buffer B capable of storing one section information. I have. One style data read from the disk of the external storage device 4 is written in the direct area A, and section information of one currently designated section of the style data written in the direct area A is written in the read buffer B. Is written.

When a section is changed, section information of a new section is read from the style data written in the direct area A and is written into the read buffer B. Further, as described later, when the disc direct switch 64 is operated during style reproduction and style data is selected by the style selection switch 65, one selected style data is read from the disc and the direct area A is read. Is written to. If the style buffer is not being played back when the style data selection operation is performed, the read buffer B
Is selected, the intro section information of the selected style data is written.

As described above, the direct area A is the RAM
3 is always reserved as a dedicated writing area (dedicated recording area), and the only area in which style data can be written is only this, so that the capacity of the recording area in the RAM 3 is not squeezed.

FIG. 4 is a flowchart of a main process of the performance information setting program executed by the CPU 1, FIG. 5 is a flowchart of a disc direct process, and FIG. 6 is a flowchart of an interrupt process of a style reproduction. The operation will be described.
Although a detailed description is omitted, detection of a key press / release operation on the keyboard 5 and normal sound generation and mute processing corresponding to the key press / release operation are executed by interruption processing to the main processing.

In the main process of FIG. 4, in step S1,
Initialization processing such as resetting various flags such as a RUN flag indicating whether or not style reproduction is being performed (setting the RUN flag to “0”), initializing the reading buffer, and initializing various functions of the main body panel is performed. . Next, step S2
It is determined whether or not the style switch 63 has been operated. If no operation has been performed, the process proceeds to step S7. If an operation has been performed, the process proceeds to step S7.
At 3, it is determined whether or not RUN = 0. If RUN = 0, the style is being reproduced, and the process proceeds to step S7. If RUN = 0, the style is not being reproduced, so that in step S4, for example, the name of the preset style data recorded in the ROM 2 in the main body is displayed on the LCD. It is displayed on the screen 7, and in step S5, a process for selecting a desired style from the displayed style data is performed. And
In step S6, the section information of the intro of the selected style data is written in the read buffer B in the RAM 3, and the process proceeds to step S7. Thus, step S
The processing of 4 to S6 is executed when the style is not being reproduced, and is a processing for using the preset style data in the ROM 2.

Next, in step S7, the presence or absence of operation of the disk direct switch 64 is determined. If there is no operation, the process proceeds to step S9. If there is operation, the disk direct process of FIG. 5 is performed in step S8 and the process proceeds to step S9. move on.
As can be seen from this flowchart, the disk direct processing can be executed irrespective of whether or not style reproduction is being performed. In step S9, it is determined whether or not there is a style reproduction start operation by the style reproduction start switch 61. If there is no operation, the process proceeds to step S11.
Then, "1" is set to the RUN flag to enable a style reproduction process by an interrupt process described later.
Proceed to 1.

In step S11, it is determined whether or not there is a change operation of the reproduction section by the section change switch 66. If there is no change operation, the process proceeds to step S13. If there is a change operation, the process proceeds to step S12. The section information corresponding to the selected section is read from and written into the read buffer B in the RAM 3. That is, when the preset style data is selected, the section information of the selected new section of the selected style data in the ROM 2 is written into the read buffer B, and when the style data of the disc is selected, The section information of the selected new section of the style data in the direct area A is written to the read buffer B. In the process of step S12, if the style is being reproduced, the section information is written when the reproduction of the style has advanced to the bar position (bar line position).

The processing time for writing one section of information to the read buffer does not significantly affect the style reproduction operation (interrupt processing), and the writing processing interrupts the style reproduction. There is no noticeable delay in the processing operation.

Next, in step S13, it is determined whether or not an operation for ending the style reproduction by the style reproduction end switch 62 has been performed. If no operation has been performed, the process proceeds to step S15. And set the RUN flag to "0", and then go to step S1.
The process proceeds to step S15, where other processing is performed in step S15, and the process proceeds to step S16. In the other processing in step S15, disc replacement in the external storage device 4, editing processing of various data, reproduction of song information (data for reproducing one tune different from style data), and other control elements 6 to perform setting processing on the main body panel. Then, in step S16, it is determined whether there is an operation for instructing the end of the main process. If there is no operation for ending the main process, the process returns to step S2. If there is an operation for ending the main process, the process ends.

In the disk direct processing shown in FIG. 5, it is determined in step S21 whether or not a disk is inserted. If the disk is not inserted, the process returns to the original routine. If the disk is inserted, the process returns to step S22. In step S23, for example, a name of the style data recorded in the style data is displayed on the liquid crystal screen 7. In step S23, a process for selecting a desired style from the displayed style data is performed. Then, in step S24, the selected style data is read from the disk and written to the direct area A in the RAM 3, and in step S25, the currently selected section (such as a change operation set on the main body panel such as a change operation in step S11) is performed. Section information is written into the read buffer B in the RAM 3 and the process returns to the original routine.

The processing in step S25 is performed in detail as follows. That is, during the style reproduction, step S
When the writing process of step S24 is started, the section information is written to the read buffer B at the timing of the first bar line after the end of the writing of step S24. Thus, until the writing of the style data in step S24 is completed, in the style reproduction by the interrupt processing, the generation of the musical tone based on the section information currently recorded in the reading buffer B is repeatedly executed, and a new sound is generated from the bar line position. Changed to tone generation by style data. By this operation, it is possible to avoid such inconveniences that a time period during which the style is not reproduced occurs when the style writing to the direct area A takes a long time, or that the style reproduction corresponding to the section change during the style writing is not performed. be able to.

In the style reproduction interruption process shown in FIG. 6, it is determined in step S31 whether RUN = 1 or not, and
If N = 1, the process returns to the original routine. If RUN = 1, data is read from the read buffer B in step S32, and it is determined in step S33 whether the read data is end data. If it is end data, the read position is returned to the head position of the read buffer B in step S34, and the process returns to step S32. If the read data is not end data in step S32, various processes are performed on the read data in step S35, and the process returns to the original routine. In the various processes in step S35, various settings based on the setting information, clock count and timing determination, tone generation or silence based on the music information timing data and event data, and the like are performed.

By the above-described style reproduction interrupt processing,
Until there is a section change instruction or a style change instruction, a musical tone with the same section information is repeatedly reproduced.

As described above, when using the style data recorded on the disk of the external storage device 4, the style data is displayed on the liquid crystal screen 7 by operating the disk direct switch 64, and the style is selected by the style selection switch 65. By simply selecting, style reproduction can be performed based on desired style data. That is, RA
Only a direct area A in which one style data can be written is secured in M3, without squeezing the recording area in the RAM 3, and style data recorded on the disc can be arbitrarily selected during style reproduction. Since it can be switched and used, various styles can be reproduced.

The present invention is not limited to the embodiments described above, but may take various forms. For example, the style data is not limited to that of the above-described embodiment, and may be recorded in any of the conventionally used data formats for style reproduction or automatic performance. As the section information included in the style data, a plurality of types of intro, fill-in, main, and ending may be recorded.

In the embodiment, the preset style data in the ROM 2 cannot be selected during the style reproduction. However, the preset style data may be selectively changed during the style reproduction.

As a method of selecting a style from within the disc using the disc direct switch 64, for example, it is assumed that a desired style is selected while pressing the disc direct switch, and that the selection is completed when the disc direct switch is released. The writing operation of the selected style data to the direct area A may be started. This makes it easier for the user to recognize what kind of operation is currently being performed, which leads to an improvement in operability.

The style switch 63 and the disc direct switch 64 may be one switch. In this case, after the operation of the switch, the style data in the main body (in the ROM) and the style data in the disc are displayed, and the operation of the above-described embodiment depends on where the selected style data is recorded. along,
Subsequent processing may be appropriately changed.

In the embodiment, only one direct area is provided. For example, if two direct areas are provided and used alternately, the processing at the time of switching the reproduction between the style data in the disc can be performed quickly. Can be done. For example, it is possible to save the time for waiting for the end of writing the style data in the direct area.

In the above embodiment, when style data is selected from the disk during style playback, section information corresponding to the currently set section is selected and played back. For example, section information corresponding to a predetermined section (fill-in, intro, etc.) may be selected and reproduced.

When style data in the disc during style reproduction is selected, section information corresponding to the currently set section is preferentially written into the direct area, and as soon as the preferentially written section information is written ( As soon as the writing of the section information for one section is completed), the music being reproduced is changed to the one based on the section information written with priority, so that the style data in the disc can be more quickly written. Playback switching can be realized.

At the time of selecting style data in a disc during style reproduction, the user may first be allowed to select which section information is to be written. Thereby, the switching of the reproduction style can be performed quickly.

The section to be reproduced may be switched not at the bar line position as in the above-described embodiment, but immediately at the time of selecting style data or selecting a section.

In the above embodiment, the case where the performance information setting program is recorded in the ROM 2 has been described. However, the performance information setting program is not recorded in the ROM 2 and a hard disk, a floppy disk, a CD-RO
An external storage device 4 such as an M or MO disk may be used. For example, a performance information setting program is recorded on a CD-ROM, and the performance information setting program is stored on the hard disk from the CD-ROM, and is stored in a hard disk.
By reading in the AM3, the CPU can perform the same operation as when the performance information setting program is stored in the ROM. In this way, a new installation, addition or version upgrade of the performance information setting program can be easily performed. Alternatively, the performance information setting program may be recorded on a floppy disk, a magnetic disk (MO), or the like, and supplied to the RAM 3 or a hard disk.

The performance information setting program may be downloaded by using the communication interface 11 of the electronic musical instrument of the embodiment. In this case, for example, by connecting to a communication network 12 such as a LAN (local area network), the Internet or a telephone line, and receiving a performance information setting program and style data from a server computer via the communication network 12, Record it on your hard disk and download is complete. In this case, the communication interface 11 is not limited to a dedicated MIDI interface, but may be a MIDI interface using a general-purpose interface such as RS-232C, USB (Universal Serial Bus), or IEEE1394.

The present invention is not limited to the electronic musical instrument having the tone generator circuit and the automatic accompaniment function as in the above embodiment.
Each device may be connected using communication means such as IDI or various networks.

The present invention is not limited to the keyboard instrument as in the above embodiment, but may be a stringed instrument type, a wind instrument type, a percussion instrument type, or the like. Moreover, you may apply to an automatic performance piano.

In the above embodiment, the format of the style data is "event + absolute time (timing data)" in which the occurrence time of the performance event is represented by the absolute time in the music or bar. However, the present invention is not limited to this. For example, "event + relative time", in which the event occurrence time is represented by the time from the immediately preceding event (timing indicated by the number of clocks), played with the pitch and note length of a note or the rest and rest length A memory area is secured in a format of “pitch (rest) + note length” representing data or a minimum resolution of performance (clock of the embodiment), and a memory area corresponding to the time when a performance event occurs is stored. The so-called "solid method" that stores performance events
And any other format.

In the above embodiment, the case of an electronic musical instrument has been described. However, the present invention can be implemented in the form of a personal computer and application software. In this case, the application software may be stored in a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory and supplied to a personal computer as described above, or may be supplied via a network. Is also good.
