Description

  The present invention allows a user to easily and quickly set a performance setting suitable for a piece of music that the user wants to play based on a performance setting record prepared in advance, and to read out and use music content associated with the performance setting. The present invention relates to an electronic music apparatus and a program that can be used. In particular, the present invention relates to a technique in which a user can easily create a new performance setting record by associating desired music content with an accompaniment style.

Conventionally, for example, accompaniment style (style data), tempo, timbre, and other various settings related to performance have been defined to collectively set performance settings suitable for manual performance of user-desired music. A large number of performance setting records (hereinafter referred to as MF records), which are a combination of setting information and attribute information for defining the song name, genre, etc. for searching the setting information, are prepared in advance. An MF record corresponding to desired music data (music content) is searched based on the attribute information, and performance settings suitable for the music that the user wants to play are set easily and quickly based on the setting information of the searched MF record. An electronic music apparatus such as an electronic musical instrument equipped with a so-called music finder (MF) function is known. An example of the device related to such a device is the device described in Patent Document 1 shown below.
JP 2006-276749

  The above-described conventional apparatus also associates music content such as automatic performance data and musical score data related to music with an MF record including attribute information and setting information (specifically, music content is stored). Content acquisition information that points to the location where According to this, in addition to the user searching for a desired MF record and performing performance setting, the music content corresponding to the content acquisition information of the searched MF record is stored in the own device or the server. The music content can be read and used. Therefore, the user can easily enjoy the manual performance of the music including accompaniment while listening to the model regarding the music to be played or while watching the score displayed on the screen.

  By the way, in the conventional apparatus, the MF record in which the existing music content and the accompaniment style are associated with each other is provided in advance by a manufacturer (content provider) or the like, and the user externally receives the MF record prepared by the content creator. It can be acquired from a storage medium or a server connected via a communication network such as the Internet. However, preparing all the MF records that are desired by all users regarding all the music contents that can be acquired by the content provider in advance is that the number of music contents is enormous, The combination with the accompaniment style is practically impossible because there are various combinations depending on the arrangement, and they are all different (that is, they cannot be uniquely determined). Therefore, even if the user newly acquires music content, it is more common that the user-desired MF record is not provided from the content provider regarding the acquired music content.

  Therefore, when a user newly acquires music content for which no MF record is provided, the user himself must create an MF record in which a desired accompaniment style is associated with the acquired music content. The user needs to search for a desired accompaniment style from a huge number of existing accompaniment styles and associate it with the music content. However, it takes a very long time for the user to specify the desired accompaniment style. That is, in the conventional apparatus, the user has to search for a desired accompaniment style from among many accompaniment styles, and selectively selects one of the acquired music content and existing accompaniment styles. It is practically difficult to create a new MF record that the user himself / herself needs in association.

  The present invention has been made in view of the above points, and the user can easily create a new performance setting record (MF record) by associating a desired music content with an accompaniment style. It is an object of the present invention to provide an electronic music apparatus and program.

An electronic music apparatus according to the present invention is an electronic music apparatus capable of setting an accompaniment style for automatic accompaniment and appropriately using music content associated with the accompaniment style, wherein Setting information including at least an accompaniment style for performing performance settings suitable for performance, attribute information regarding the music associated with the accompaniment style, and designation information specifying music content related to the music; A record specifying means for searching an original record in which the specified information is not recorded among the records according to a predetermined condition, and specifying one original record based on a search result, and the specifying Search for music content including music information corresponding to the attribute information in accordance with the attribute information of the original record Stage and a selection means for selecting one of the music content to the search, the record comprising a combination of designation information for designating the setting information and the music content that the attribute information and said selected original records that the specific And generating means for generating the record and storage means for storing the generated record.

According to the present invention, an original record in which no designation information is recorded is searched according to a predetermined condition, one original record is specified based on the search result , and the attribute information is handled according to the attribute information of the specified original record. Search for music content containing music information. Then, in response to selecting one music content from the search, a record is generated by combining the setting information and the attribute information of the identified original record with the designation information designating the selected music content. Stored in the storage means . That is, the original record, includes a setting information comprising at least accompaniment style for performing performance setting suitable for playing the desired song, and attribute information relating to the music associated with the該伴Kanade Style are, but because specifying information that specifies the music content related to the music does not have, by Rukoto combining a specification information for specifying the music content that the specific thereto, a combination of all necessary information Records can be created and stored. In this way, the user himself / herself creates a new performance setting record by associating the desired music content with the accompaniment style, and only stores the music content to be searched for when the original record is specified. It will be easy to do.
In a preferred embodiment of the present invention, before Symbol record specifying means acquires the accompaniment style as the predetermined condition, it retrieves the original record comprising a setting information accompaniment style the acquired, the original records the search The one original record is specified by selecting one of them. According to this, when a user acquires an accompaniment style, a user can easily create a new performance setting record associated with a desired music content.

  The present invention may be constructed and implemented not only as an apparatus invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

According to the invention, that the user himself creates and stores a record for performance setting new associates the desired music content and accompaniment style, selects a music content to be searched with the specific original record There is an effect that it can be easily performed only by this.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing an embodiment of the overall configuration of an electronic music apparatus according to the present invention. The electronic music apparatus shown in this embodiment is, for example, an electronic musical instrument, and is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic music apparatus. ROM 2, RAM 3, detection circuits 4 and 5, display circuit 6, sound source / effect circuit 7, storage device 8, and communication interface (I / F) 9 are connected to the CPU 1 via a data and address bus 1D. ing.

  The ROM 2 stores various control programs executed by or referred to by the CPU 1, various data, and the like. The RAM 3 is used as a working memory for temporarily storing various data generated when the CPU 1 executes a predetermined program, or as a memory for temporarily storing a currently executing program and related data. The A predetermined address area of the RAM 3 is assigned to each function, and is used as a register, a flag, a table, a temporary memory, or the like. The performance operator 4A is, for example, a keyboard provided with a plurality of keys for selecting the pitch of a musical tone, and has a key switch corresponding to each key. 4A (keyboard or the like) can be used not only for manual performance by hand-playing by the user itself, but also as means for designating music contents such as MF records, song data and score data. The detection circuit 4 generates a detection output by detecting the pressing and releasing of each key of the performance operator 4A.

  A setting operator (switch or the like) 5A displays, for example, a number of MF records stored in the database, specifies a record to be used from among them, a switch for instructing start / stop of automatic accompaniment based on an accompaniment style, It is configured to include various operators such as a switch for instructing start / stop of automatic performance based on song data and a switch for instructing score display based on score data. Of course, the setting operation element 5A has a numeric data input numeric keypad and a character data input keyboard for selecting / setting / controlling pitches, tones, effects, etc., or a pointer displayed on the display 6A. Various operators such as a mouse for operating the above may be included. The detection circuit 5 detects the operation state of the setting operation element 5A, and outputs switch information and the like corresponding to the operation state to the CPU 1 via the data and address bus 1D.

  The display circuit 6 displays various screens (not shown) such as a screen displaying a search result of various data and a screen displaying a score on a display 6A composed of, for example, a liquid crystal display panel (LCD) or a CRT. Of course, various data stored in the ROM 2 and the storage device 8 or the control state of the CPU 1 are displayed. In this embodiment, the user selects desired data on the data search result screen displayed on the display 6A, so that the accompaniment style and song data are loaded, and the MF record in which the accompaniment style and song data are associated with each other. Can be newly created (details will be described later). It should be noted that the display 6A may be a touch panel, and in that case, it is needless to say that the display 6A includes means for detecting that the screen has been touched.

  The tone generator / effect circuit 7 can simultaneously generate musical tone signals on a plurality of channels, and inputs performance data generated based on data and song data or accompaniment style given via the address bus 1D. A musical sound is generated by synthesizing musical sounds based on the information. The tone signal generated from the sound source / effect circuit 7 is generated from a sound system 7A including an amplifier and a speaker. Any conventional configuration may be used for the configuration of the sound source / effect circuit 7 and the sound system 7A. For example, the tone generator / effect circuit 7 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be configured with dedicated hardware, or by software processing by the CPU 1. It may be configured.

  The storage device 8 is configured with a built-in database capable of storing a large number of MF records and the like for performing performance settings suitable for manual performance of music desired by the user, for example, accompaniment style and song data (described later). (See FIG. 2). In addition to these, various control programs executed by the CPU 1 may be stored. When the control program is not stored in the ROM 2 described above, the control program is stored in the storage device 8 (for example, a hard disk) and is read into the RAM 3 to store the control program in the ROM 2. It is possible to cause the CPU 1 to perform the same operation. In this way, control programs can be easily added and upgraded. The storage device 8 is not limited to a hard disk (HD), but may be a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). Any storage device may be used as long as it uses a storage medium in the form. Alternatively, a semiconductor memory such as a flash memory may be used.

  A communication interface (I / F) 9 is an interface for transmitting and receiving various information such as a control program, accompaniment style, song data, and MF record between the apparatus and an external device (not shown) such as a server or a MIDI device. It is. The communication interface 9 may be, for example, a MIDI interface, a LAN, the Internet, a telephone line, or the like, and may include both wired and wireless ones.

  In the electronic music apparatus described above, the performance operator 4A is not limited to the form of a keyboard instrument, but may be of any type such as a stringed instrument, a wind instrument, or a percussion instrument. In addition, the electronic music apparatus is not limited to one in which the performance operator 4A, the display 6A, the sound source / effect circuit 7 and the like are built in one apparatus body, but each is configured separately, and communication means such as a MIDI interface and various networks are provided. Needless to say, the apparatus may be configured to be connected to each other.

  FIG. 2 is a conceptual diagram showing the data structure of various data stored in a built-in database configured in the electronic music apparatus according to the present invention. The built-in database (storage device 8) can store at least an accompaniment style (style data) T, song data O, and MF record N as various data. These data are not limited to those stored in advance in the electronic music device (that is, created by the manufacturer of the electronic music device), but are additionally stored by the user (content provider) or newly created by the user. What is newly created by other users and registered in the server can be acquired via the communication network, and can be replaced or additionally stored with existing data.

  The accompaniment style T includes at least style attribute information and entity data (track data and note conversion data). The style attribute information is information registered in the database (which makes it possible to search for what kind of music and music genre each accompaniment style is suitable for use in) and includes the style name and other style attribute information . The style name is a name unique to each accompaniment style. The other style attribute information includes, for example, an actual music name that matches the accompaniment style image, a keyword that can be associated with the accompaniment style image, tempo, tone color, and the like.

  Track data is basic accompaniment data for each of multiple sections (intro, main, fill-in, ending, etc.) for each of multiple tracks (chord backing, base, rhythm, etc.). The accompaniment data of each track excluding the rhythm track is created based on a predetermined chord, and is transcoded according to a chord designated at the time of performance. The chord is C major, and the pitch in the accompaniment data is converted to match the chord specified at the time of performance.The chord specified at the time of performance may be variable, and is specified in advance in the order of performance in the note conversion data. Alternatively, the user may input the accompaniment data as appropriate during the reproduction of the accompaniment data. Table or the like to be used in the over-de conversion may store the information for setting the characteristics of the code conversion.

  The song data O (music content) includes at least song information (attribute) and entity data (track data or waveform data). The music information is information registered in the database (which makes it possible to search for which music each music data is), and includes, for example, a music title, artist name, and other music information. The song name and the artist name are an actual song name for specifying each song data and an individual name that composes, composes, sings, etc. the song. The other music information is, for example, a keyword that can be associated with an image of music data. Substantive data such as track data and waveform data is data constituting the substance of music data. The song data may be automatic performance data such as SMF format or audio data in WAV format or MP3 format.

  The MF record N is data for performing performance settings suitable for manual performance of music desired by the user, and includes attribute information, setting information, and content specifying information. The attribute information is information for searching for the record. For example, the attribute relating to the music associated with the accompaniment style such as MUSIC name (song title, song image title, etc.), keyword, music genre, beat (time signature), artist name, etc. Contains information indicating. The setting information is data for automatically performing performance settings suitable for a user to play a specific music piece using an electronic music apparatus, and includes accompaniment style name, tempo, and style data designation information. The content specifying information includes a song name and song data designation information. In one MF record N, the MUSIC name of the attribute information and the song name of the content specifying information may be the same or different (here, the same case is shown as an example).

  For example, the ID or path (full path) of each data file is recorded in the style data designation information or the song data designation information. That is, the accompaniment style and song data are stored in a storage area or the like prepared in the storage device 8 such as the ROM 2 or the flash memory, so that the data is stored in accordance with the path (full path) specifying the ID and storage location of each data file. It can be specified. Furthermore, the song data does not necessarily need to be stored on the electronic music apparatus side, and the song data stored in the server may be accessed each time without downloading the song data, and the corresponding song data may be used. For this reason, in such a case, a URL or the like designating the storage location of the song data in the server may be recorded in the song data designation information.

  The user can arbitrarily create and store in advance an MF record in which the content specifying information is empty (not recorded) in the built-in database. Then, with the execution of “record generation processing” (see FIG. 4 or FIG. 5 described later), the previously created content specifying information is an empty MF record or the content specifying information acquired from the server is an empty MF record. (See FIG. 3), information for specifying song data is automatically written in the content specifying information, and an MF record N in which a user-desired song and an accompaniment style are associated is newly created. It has become. Details will be described later.

  Next, FIG. 3 shows the data structure of the MF record stored in the server that can transmit and receive data to and from each other by connecting to the electronic music apparatus shown in FIG. 1 via a communication network. FIG. 3 is a conceptual diagram showing the data structure of the MF record included in the database configured in the server. The server is not limited to the MF record shown here but can store accompaniment styles and song data (illustration and description are omitted here), and an electronic music device connected via a communication network Of course, these data can be transmitted and received between each other.

  Also for the server, a plurality of MF records (R1 to R3) in which attribute information, setting information, and content specifying information are aggregated into one record are stored in the database 8. Each information is the same as the MF record stored on the electronic music apparatus side. Here, in order to compare and understand record 1 (R1) and record 2 (R2), different accompaniment styles (JazzWaltz1 and VienneseWaltz1) are specified, but the same MUSIC name (Kaiser Walzer) Records are prepared in advance (that is, arrangements are different). In addition, as can be understood by comparing record 2 (R2) and record 3 (R3), each has the same accompaniment style (VienneseWaltz1) but different MUSIC names (Kaiser Walzer and An der schonen, blauen. ..) are also prepared in advance (that is, songs are different). Further, these MF records are data in which the music data specifying information is empty, that is, data in which no information regarding the music data is recorded (described as music data undecided in the figure).

  As described above, the server does not associate the accompaniment style and the song data in advance, and there are a plurality of MF records that specify different (or the same) accompaniment styles even with the same (or different) MUSIC names. Many are available. Then, the user selects a desired record from among the MF records in which the content specifying information is empty (referred to as an original record for the sake of distinction from the MF record in which information is described in the content specifying information). Thus, it is possible to easily create a new MF record in which desired music data and an accompaniment style are associated with each other by the user's own hands (details will be described later).

  Next, “record generation processing” for creating a new MF record in the electronic music apparatus shown in the present embodiment will be described. First, “record generation processing” in which a user specifies music data and creates a new MF record in which a desired accompaniment style is associated with the music data will be described. For example, after a user acquires song data, plays the acquired song data, listens to the song, and enjoys the song, he / she wants to play this song with his / her own electronic music device. is there. However, some users do not know how to set performance settings for the song. In particular, beginners do not know at all what accompaniment style should be selected and how much tempo should be specified in the automatic accompaniment function. In such a case, if the song that the user wants to play is, for example, a famous song, an MF record (however, the original record) that defines the optimal performance settings for playing this song is previously set by the content provider or another user. It may be provided on the server. Alternatively, before obtaining the song data, the user has created an MF record (original record) that defines the optimal performance settings for this song. Of the MF records stored in the electronic music device, the MF record is It may just be missing.

  Therefore, in the first embodiment shown in FIG. 4, the user searches for the original record as a candidate in both the user's own machine and the server, and the acquired song data in the original record arbitrarily selected from the search results is obtained. By associating, an MF record in which an accompaniment style suitable for music data is associated can be newly created. FIG. 4 is a flowchart showing an example of the “record generation process”. Hereinafter, the processing will be described with reference to FIGS. 2 and 3 described above together with FIG.

  Step S1 acquires (identifies) song data in accordance with a user's designation. At this time, if the song data O (the song name Kaiser Walzer in FIG. 2) has already been stored in the own device, the song data is only specified. On the other hand, if it is not already stored in the own device, it is necessary to obtain the song data O from another and store it in the own device. For example, when the user finds desired music data O at a site (server) on the Internet, the music data O is downloaded from the server to the own device. Alternatively, when the music data O is stored in a portable storage medium such as a USB memory connected to the own device, the song data O is copied from the portable storage medium to the storage device 8 of the own device. In step S2, a song name (Kaiser Walzer), which is song information of the obtained (specified) song data, is read.

  In step S3, a search engine (software program) of the built-in database or a server connected via a communication network is instructed to search for a record using the read song name (Kaiser Walzer) as a search key. That is, the search engine of the own machine searches the MF record stored in the built-in database (when the user already has the corresponding original record), or the server stores the original record stored in the server database. Search by a search engine (if the user does not have a corresponding original record).

  Here, an example is shown in which the search is performed between the song data and the original record according to the song name and the Music name, but other song information of the song data may be used. For example, an artist name (Johann Straus II) may be used. Further, the search method may be a generally known method such as a search using a combination of a plurality of attributes as a search condition, or a search using partial match instead of complete match. For example, when a MUSIC name and a song name are searched by partial matching, the MUSIC name and song name of a newly created MF record are only partially matched (for example, Walzer). In such a case, it becomes easy to create more various MF records.

  In step S4, the search result is acquired and presented to the user (for example, screen display). Step S5 prompts the user to select one source record from the presented search results. That is, the original record of the search result is not limited to one and may be plural. For example, in the example shown in FIG. 3, when searching for the song name “Kaiser Walzer”, not only the original record 2 (R2) suitable for playing a classical song by Johann Straus II composition but also by Johann Straus VIII composition An original record 1 (R1) suitable for playing a modern jazz song is also presented as a search result. In this way, since the impression of a song can change if the composer, arrangement, etc. are different even with the same song name, several original records (R1, R2) associated with different accompaniment styles are candidates for the user. The desired original record is selected from the search results presented to the user.

  In step S6, the music title and music data designation information are automatically added to the empty content specifying information in the selected original record, and the record is stored (stored) in the built-in database. That is, the song name read from the song data and the file path on the internal drive that is the storage destination of the song data are automatically written in the original record that has been acquired in advance or newly received from the server. Is stored in the built-in database as a new MF record (N). After a new MF record (N) is created in this way, the user uses this to listen to music data as a model for appreciation and practice, or to practice performance by applying performance settings according to the setting information. be able to.

  In addition, when the user himself / herself has previously generated an MF record in which only the content designation information is recorded in the built-in database, the attribute information and the setting information included in the original record received from the server are copied and written, A new MF record may be created. In addition, when an original record is to be received from the server even though an MF record has already been created (music name and song data designation information is recorded), the MF record can be overwritten and re-created. The processing may be stopped (the existing one will be left as it is), or two sets of MF records, which are already recorded and newly created records, may be recorded. Either may be selected by the user.

  It is possible to create a new MF record without acquiring music data from the server (that is, music data is not stored in the built-in database). That is, without acquiring song data from a site (server) on the Internet, a song name and a URL indicating the storage location of the server storing the song data are acquired, and these are written into the content designation information and newly written. An MF record may be created.

  By the way, a user sometimes wants to play a song that he / she hears on his / her own machine. In such a case, if the user creates a new MF record that defines the performance settings for the song and keeps it, the same performance settings can be reproduced by using the created MF record in subsequent performances. It is convenient because it is possible to listen to a model about the song when the song data is available later. Therefore, in the second embodiment shown in FIG. 5, the user first searches for a candidate MF record directly in both the user's own machine and the server, and the existing record in the original record arbitrarily selected from the search results or By associating newly acquired music data, a new MF record can be created. FIG. 5 is a flowchart showing another example of the “record generation process”.

  In step S11, “record identification processing” is executed. Here, the “record specifying process” includes a first method in which the user specifies an original record that defines a desired accompaniment style from among the original records searched according to the input of a search condition by the user, The user specifies the original record that defines the desired song from the original records searched based on the desired accompaniment style specified in advance (that is, first acquires the accompaniment style and then specifies the original record based on it) There is a second method. Hereinafter, each will be described separately.

  FIG. 6 is a flowchart showing an example of the “record specifying process”, which is a process for realizing the first method. Step S21 prompts the user to input a search condition for searching the original record (may be an appropriate condition such as a music name) on the screen. A step S22 instructs a search engine of the built-in database or a server connected via the communication network to search for an original record that matches the input search condition. A step S23 acquires a search result. Step S24 allows the user to select (specify) one original record from the search result. In step S25, when the selected original record is an original record stored in the server, the record is acquired from the server and registered (stored) in the built-in database. For example, in the example shown in FIG. 3, when searching with the music name “Kaiser Walzer”, the original records (R1, R2) are presented as search results, so the user may select (specify) one of them. it can.

  On the other hand, FIG. 7 is a flowchart showing another embodiment of the “record specifying process”, which is a process for realizing the second method. This process can be used, for example, when a user obtains an accompaniment style from a server or portable storage media, searches for a song that can use the accompaniment style, and wants to play or listen to it, or if the user has already This is especially useful when you want to use the accompaniment style stored in the electronic music device, search for a new song that is not registered in the built-in database, and want to play or listen to the song. is there.

  In step S31, the accompaniment style designated by the user is acquired (specified). A step S32 reads the style name from the accompaniment style. A step S33 instructs the server to search for an original record that uses the same accompaniment style as the read style name. A step S34 acquires a search result. In step S35, the user selects (specifies) one original record from the search result. In step S36, the original record selected from the server is acquired and registered (stored) in the built-in database. For example, when the accompaniment style T of FIG. 2 is acquired (specified), it is the style name “VienneseWaltz1” of the accompaniment style T, and when the original record is searched based on this, the original record (R2, R3) is obtained. Since it is presented as a search result, the user can select (specify) any of them.

  Returning to the description of FIG. 5, the song data designation information is not recorded in the original record (one of R1 to R3) specified as described above. If such an original record is used, performance settings can be made, but the user is not able to listen to the model immediately if necessary, and is troubled. However, the sample song data may have been downloaded before but forgot where it was saved, or it may only be stored on the server in the first place. Therefore, it is necessary to search for music data based on the Music name (Kaiser Walzer or Ander schonen, blauen ...), which is one of the attribute information of the identified original record. A step S12 instructs the search engine of the built-in database or a server connected via the communication network to search for song data having a song name corresponding to the music name of the original record. A step S13 acquires a search result. A step S14 causes the user to select (specify) one piece of music data from the search result. For example, when the user specifies the original record R2 (Music name “Kaiser Walzer”), music data O (song name “Kaiser Walzer”) as shown in FIG. 2 is retrieved, and the user selects the music data O. Can do.

Step S15 downloads and stores the song data from the server when the specified song data is not stored in the built-in database and is stored only in the server. This allows the user to listen to the song data without a network connection. Alternatively, the song data stored in the server may be distributed every time the user wants to listen without downloading the song data. If the accompaniment style used in the specified original record (any one of R1 to R3) is not stored in the built-in database, the accompaniment style may be downloaded in the same manner as the song data. A step S16 creates a new MF record (N) by appending to the original record (one of R1 to R3, which is N in FIG. 2) specifying the music data designation information. At the time of additional recording, if song data is stored in the built-in database, the song data designation information becomes the file path, and if it is stored in the server, the URL designates the storage location as already described. In step S17, music information is acquired from the music data and added to the original record (any one of R1 to R3) as necessary.

As described above, by selecting one of the original records searched according to the specification of the music content and recording the information specifying the specified music content in the specification information of the selected original record, An accompaniment style for automatic accompaniment is set, and a new MF record for appropriately using music content associated with the accompaniment style is generated. Thus, the user himself / herself creates a performance setting record (MF record) by associating the desired music content with the accompaniment style, and selects the original record searched according to the specification of the music content. Just be able to do it easily.
Further, the attribute information (for example, the MUSIC name of the specified original record) is added to the specified information of the original record specified by the user selecting from among the extracted according to the search condition or specified in accompaniment style. The MF record is newly generated by recording the information specifying the music content searched and selected based on (1). Even in this case, the user himself / herself creates a performance setting record (MF record) by associating the desired music content with the accompaniment style, so that the user directly selects the original record or acquires the accompaniment style. Just be able to do it easily.
In addition, a variety of ways of enjoying can be achieved by uploading records created by individual users in association with arbitrary music contents and accompaniment styles to a server, etc., and widely providing them to other users. Also become.

  Note that the type of music content that can be associated with the accompaniment style in the MF record is not limited to song data, and may be appropriate data such as score data, fingering data, music video data, and the like.
