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

When using the style data recorded on the disc, a list of the style data on the disc is displayed on the display unit, and all the style data or a plurality of style data to be used are displayed to the user. All of the selected style data is loaded from the disc into the RAM in the electronic musical instrument body by the operation of the load operator after the selection operation is completed.

[0004]

In the conventional electronic musical instrument as described above, when the style data in the disc is used, the style data in the disc is selected by first selecting the style data and operating the load operator. RAM
However, since the style data can be reproduced (hereinafter referred to as “style reproduction”) for the first time, the setting operation until the automatic accompaniment performance is complicated and troublesome.

Further, in the conventional electronic musical instrument, before the style is reproduced, all the style data to be used are preliminarily read by the R side of the main body side.
It had to be loaded in AM and was not practical. For example, there is a problem that it is not possible to reproduce the style data that comes to mind during the performance, so that various style reproduction cannot be enjoyed. If you load all the style data on the disc into the main unit, you can change the style data at will during style playback, but in that case, most of the recording area in the main unit's RAM will be saved. It is used and is not preferable for other processing.

An object of the present invention is to make it possible to perform a variety of style reproductions while simplifying the setting operation of style data (performance information) from within the disc and keeping the recording area used on the main body side small.

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 the plurality of style numbers are stored in the external storage device 4.
Discs (eg, floppy discs). 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 of the intro, fill-in, main, and ending sections.

"Intro" is an accompaniment pattern to be inserted at the beginning of a song, "Fill-in" is an accompaniment pattern to be inserted at a joint of a measure or a passage, and "Main" is a basic pattern throughout the song. An "accompaniment pattern" for accompaniment is an accompaniment pattern to be inserted at the end of a piece of music. Each section information consists of section identification data, setting information, music information and end data,
The section identification data is data for identifying whether the data from the section identification data to 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 regarding the sound source and various settings set on the main body panel when style reproduction is performed for the section. Due to
Tones and effects are specified. The music information is recorded with event data for reproducing the music of the section in the order of progression of the music, and data of one or several bar length is recorded. Note that the music information of this embodiment includes event data such as note-on and note-off,
It is recorded together with timing data indicating the timing of the event.

The style data (each section information) includes information for rhythm performance, information for bass performance, and information for chord performance. Furthermore, each style data may include chord progressions corresponding to the style, and this chord progression data records chord root notes and chord type information according to the progress of the performance, The information indicating the chord root note and chord type is data for converting the pitch of the bass performance information and the chord performance information during style reproduction. Furthermore, the above chord progression data is 1 for each style.
In some cases, it is recorded one by one, or in each case, one section information is recorded for each section information in the style.

FIG. 3 is a diagram conceptually showing the processing of the embodiment. In the RAM 3, a direct area A capable of storing one style data and a read buffer B capable of storing one section information are set. There is. One piece of 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 specified section of the style data written in the direct area A is written in the read buffer B. Is written.

When the section is changed, the section information of the new section is read from the style data written in the direct area A and written in the read buffer B. Further, as will be described later, when the disc direct switch 64 is operated during style reproduction and the 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. Written in. In the read buffer B, if the style is not being reproduced when the style data is selected, the ROM 2
When the preset style data of 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 secured as a dedicated writing area (dedicated recording area), and the only area in which style data can be written is, so that the capacity of the recording area in the RAM 3 is not compressed.

FIG. 4 is a flow chart of the main processing of the performance information setting program executed by the CPU 1, FIG. 5 is a flow chart of the disk direct processing, and FIG. 6 is a flow chart of the interrupt processing of the style reproduction. The control of the CPU 1 is based on each flow chart. The operation will be described.
Although detailed description is omitted, the detection of the key pressing operation on the keyboard 5 and the normal sounding and mute processing corresponding thereto are executed by interrupt processing with respect to the main processing.

In the main processing of FIG. 4, in step S1,
Performs initial setting processing such as resetting various flags such as the RUN flag indicating whether the style is being reproduced (setting the RUN flag to "0"), initialization in the read buffer, initialization of various functions of the main body panel, etc. . Next, step S2
It is determined whether or not the style switch 63 is operated, and if there is no operation, the process proceeds to step S7. If there is an operation, the step S7 is performed.
At 3, it is determined whether RUN = 0. If RUN = 0, the style reproduction is in progress, so the process proceeds to step S7. If RUN = 0, the style reproduction is not in progress. Therefore, in step S4, the preset style data recorded in the ROM 2 in the main body, such as the name, is displayed on the liquid crystal display. Displayed on the screen 7, in step S5, a process for selecting a desired style from the displayed style data is performed. And
In step S6, the intro section information of the selected style data is written in the read buffer B in the RAM 3, and the process proceeds to step S7. In this way, step S
The processes of 4 to S6 are processes for executing preset style data in the ROM 2 when the style is not being reproduced.

Next, in step S7, it is determined whether or not the disk direct switch 64 is operated. If there is no operation, the process proceeds to step S9. If there is an 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 disc direct process can be executed regardless of whether the style reproduction is being performed. Then, 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, and if there is an operation, step S10.
Then, the RUN flag is set to "1" to enable the style reproduction process by the interrupt process described later, and step S1
Go to 1.

In step S11, it is determined whether or not there is an operation for changing the playback section by the section changing switch 66. If there is no changing operation, the process proceeds to step S13. If there is a changing operation, the style data selected in step S12 is selected. The section information corresponding to the section selected from is read and written in 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 of the direct area A is written in the read buffer B. The process of step S12 is a process of writing the section information when the style reproduction advances to the bar position (bar line position) while the style is being reproduced.

The processing time for writing one section of information in the read buffer is such that the style reproduction operation (interrupt processing) is not significantly affected. There is no significant delay in the processing operation.

Next, in step S13, it is determined whether or not the style reproduction ending switch 62 has operated to end the style reproduction. If there is no operation, the process proceeds to step S15. Is muted and the RUN flag is set to "0", and step S1 is performed.
5, the other process is performed in step S15, and the process proceeds to step S16. In addition, in the other processing of step S15, the disks in the external storage device 4 are replaced, various data are edited, song information (data for reproducing one piece of music different from style data) is reproduced, and other operators are grouped. Setting processing and the like on the main body panel by 6 are performed. Then, in step S16, it is determined whether or not there is an operation for instructing the end of the main processing. If there is no operation for ending the main processing, the process returns to step S2, and if there is an operation for ending the main processing, the processing ends.

In the disc direct process of FIG. 5, it is determined in step S21 whether or not a disc is inserted. If it is not inserted, the process returns to the original routine, and if it is inserted, in step S22 the disc contents are stored. For example, the name of the style data recorded in (1) is displayed on the liquid crystal screen 7, and 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 in the direct area A in the RAM 3, and in step S25, the currently selected section (such as the change operation in step S11 is set on the main body panel). The section information of the section (current section) is written in the read buffer B in the RAM 3, and the process returns to the original routine.

The process of step S25 will be described in detail as follows. That is, step S is performed during style reproduction.
When the writing process of 24 is started, the section information is written in the read buffer B at the timing of the first bar line after the writing of step S24 is completed. As a result, until the style data writing process in step S24 is completed, in the style reproduction by the interruption process, the musical tone generation based on the section information currently recorded in the read buffer B is repeatedly executed, and a new bar line position is added. It is changed to the tone generation by the style data. This operation avoids the inconvenience that the style is not played back when the style writing to the direct area A takes a long time, or the style playback corresponding to the section change during the style writing is not performed. be able to.

In the style reproduction interrupt processing of FIG. 6, it is determined in step S31 whether RUN = 1 or not, and the RU
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 the end data in step S32, various processes are performed on the read data in step S35 to return to the original routine. In the various processes of step S35, various settings based on the setting information, clock count and timing determination, musical tone generation or mute based on the music information timing data and event data, and the like are performed.

With the above style reproduction interruption processing,
The musical sound based on the same section information is repeatedly played until there is a section change instruction or a style change instruction.

As described above, when using the style data recorded on the disc of the external storage device 4, the disc direct switch 64 is operated to display the style data on the liquid crystal screen 7, and the style selection switch 65 is used to display the style. By simply selecting, style reproduction can be performed based on desired style data. That is, RA
Only the direct area A that can write one style data is secured in M3, and the recording area in the RAM3 is not compressed, and the style data recorded on the disc can be arbitrarily selected during the style reproduction. Since you can switch and use them, you can play various styles.

The present invention is not limited to the above-mentioned embodiments and can have various aspects. 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 and automatic performance. Further, 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, but the preset style data may be selectively changed during the style reproduction.

As a style selecting operation method from the inside of the disk using the disk direct switch 64, for example, it is assumed that the desired style is selected while pressing the disk direct switch and the selection is completed when the disk direct switch is released. The writing operation of the selected style data to the direct area A may be started. In this way, the user can easily recognize what kind of operation is currently being performed, which improves operability.

The style switch 63 and the disk direct switch 64 may be one switch. In that case, after the switch is operated, the style data in the main body (in the ROM) and the style data in the disc are displayed, and the operation of the embodiment is performed depending on where the selected style data is recorded. along,
The subsequent processing may be changed as appropriate.

Although only one direct area is provided in the embodiment, for example, if two direct areas are provided and used alternately, the processing at the time of switching the reproduction of the style data in the disc can be speeded up. Can be done. For example, it is possible to omit 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 disc during style reproduction, the section information corresponding to the currently set section is selected and reproduced. Not limited to this, for example, section information corresponding to a predetermined section (fill-in or intro) may be selected and reproduced.

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

When selecting style data in the disc during style reproduction, the user may first select which section information to write. This makes it possible to quickly switch the reproduction style.

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

Further, in the above embodiment, the case where the performance information setting program is recorded in the ROM 2 has been described, but the performance information setting program is not recorded in the ROM 2 and the hard disk, the floppy disk, the CD-RO is used.

By reading in the AM3, it is possible to cause the CPU to perform the same operation as when the performance information setting program is stored in the ROM. This makes it easy to newly install, add, or upgrade the performance information setting program. Further, 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 the hard disk.

Further, the performance information setting program may be downloaded by using the communication interface 11 in the electronic musical instrument of the above 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, It is recorded on the hard disk and the download is completed. In this case, the communication interface 11 is not limited to a dedicated MIDI interface, and a general-purpose interface such as RS-232C, USB (Universal Serial Bus), or IEEE 1394 may be used to configure the MIDI interface.
