  By the way, in the conventional electronic music apparatus as described in Non-Patent Document 1 described above, even if the music is the same, the usage of the music (for example, a performance practice application or a music appreciation application) or the user's operation for the music is concerned. It is possible to reproduce (and present) musical tones in different reproduction modes according to performance proficiency levels (for example, performance skill level and musical understanding level).

  For example, music data that includes only an automatic performance-dedicated part that does not include a user-performance-specific part is prepared as a performance practice application, and a musical tone that consists of only an automatic-performance-specific part is reproduced based on this (for user performance-related parts). If the user himself / herself performs a manual performance, this is optimal for the user's performance practice), and music data including all parts is prepared for the purpose of listening to music, and based on this, musical sounds composed of all parts are prepared. It can be played back (this is ideal for the user to refer to a performance by a professional player as a model before starting performance practice). In addition, as a beginner level, song data including various settings such as slowing down the tempo or omitting some effects compared to the original song is prepared, and music is played back based on this data. Compared to this song, song data including various settings such as a faster tempo and complicated effects can be prepared and music can be reproduced based on this. And it is possible to present to the user the musical sound of the different reproduction | regeneration aspect according to these uses and levels with a screen display. In this specification, the term “musical sound” is not limited to musical sound, but is used in the sense that it may include voice or other arbitrary sounds.

  By the way, in the conventional electronic music apparatus, when presenting musical sounds of different playback modes according to these uses and levels to the user, the song data is stored for each song data prepared for each use and level prepared in advance. On the basis of the reproducible usage and level, the musical tone corresponding to the level is separately displayed separately. However, even if the music is the same based on the individual song data, the musical tones with different playback modes are displayed separately for each usage and level, so there are particularly many songs or various usages and levels. In this case, the user must search for each musical sound (song data) corresponding to the intended use and level to be reproduced with respect to the desired song by operating a predetermined operator to scroll the display. There was a problem that it was troublesome. In other words, according to the above display, the user cannot immediately know what purpose and level of musical sound can be reproduced for the desired song. In order to find (song data), the operation as described above must be performed, and it took time to reproduce. Such a problem is more conspicuous particularly in a conventional apparatus such as that described in Non-Patent Document 1 described above, which has a display means with a narrow display area in which it is difficult to present a large amount of data content at one time.

Presents storage means for storing a plurality of song data individually produced, song data acquisition means for acquiring song data for each use and level stored, and song data for each use and level capable of reproducing music. Creating means for creating a music selection list for each piece of data capable of reproducing musical sounds related to the same song according to the music information common to each song data for the obtained use and level-specific song data And a song selection list for displaying the classified song data in units of the music information, and a song according to the obtained use and level based on the created song selection list. Display means for displaying a plurality of pieces of music data that can reproduce music related to the same piece of music in units of the music information, the display means displaying the music information and displaying the music information Are displayed in association with a plurality of different usage and level information corresponding to each of the plurality of song data and the displayed music information is selected and the displayed usage and level In accordance with the selection of any of the information, a specifying means for specifying song data according to usage and level corresponding to the usage and level information and the music information, and song data according to the specified usage and level And a reproducing means for reproducing a musical sound based on the above.

  According to the present invention, even for the same song, based on a plurality of song data individually generated according to the use of the song and the user's performance level for the song, the music data that can be played back by tone and level are used. When a music selection list for presenting music is displayed, a plurality of pieces of music data capable of reproducing musical sounds related to the same music among the music data by use and level are displayed together in a common music information unit. That is, the song data for each use and level is song data that can reproduce a musical sound related to the same song even if the use and the level are different. Therefore, the song data always has common music information. Therefore, according to the music information, music data according to use and level can be classified for each data that can reproduce musical sounds related to the same music, so that all the music data acquired thereby can be classified into the music information unit. Are summarized in Then, by displaying the music information and displaying a plurality of different usage and level information corresponding to each of the plurality of music data in association with the displayed music information, the acquired music by usage and level is displayed. A plurality of pieces of music data that can reproduce musical sounds related to the same music among the data are displayed together in the music information unit. In this way, by presenting musical sounds of different playback modes according to multiple uses and levels related to the same song for each song, what kind of song data the user has and what for each song It is possible to immediately grasp whether or not the musical sound corresponding to the usage and level can be reproduced. As a result, the user can easily and quickly find and reproduce music data that can reproduce a musical tone corresponding to a desired application and level for each music as compared with the conventional art.

  According to a second aspect of the present invention, there is provided an electronic music apparatus according to the present invention, in which change information for a song is defined for each song by dividing the change information for one or more uses of the song and the performance level of the user, and one for each song.

Classifying musical sounds related to the same song according to music information for each reproducible data, creating a music selection list for displaying the classified music data in units of the music information, and generating the music based on the created music selection list A display means for collectively displaying a plurality of pieces of song data capable of reproducing musical sounds related to the same song among the song data according to possible uses and levels and the obtained song data according to uses and levels. The display means displays the music information, and the displayed music information includes one or more different uses and records corresponding to the plurality of song data. Information and the displayed music information are selected and any of the displayed usage and level information is selected, and the usage and level information is selected. And means for specifying music data according to usage and level according to the music information, and music sound playback means for playing back music based on music data according to usage and level, wherein the music playback means Generating new song data for each use and level based on the change data corresponding to the case where the song data is the original song data, and playing music based on the generated song data for each use and level With.

  According to the present invention, the original song data assigned to each song, and the usage of the song and the separately prepared song data for each usage and level of the user's performance proficiency level are mixedly stored. When these pieces of music data are sequentially obtained and presented to the user, music information units that are common to each piece of music data even if they have different uses or levels as long as they are music (song data) related to the same music Are displayed together. At that time, when the acquired song data is song data according to use and level, regarding the song data, on the other hand, when the acquired song data is original song data, change information for the original song data is displayed. Uses corresponding to the common music information for one or more uses and level-specific song data that can be generated based on the original song data based on change data defined separately for one or more uses and levels Display with level information. If the song data specified by selecting one of the displayed usage or level information is song data prepared for a usage and level prepared in advance, a musical tone is generated based on the song data. Reproduce. On the other hand, when the specified song data is the original song data, the original song data is changed based on the change data to newly generate song data according to the usage and level, and the generated song data. Play music based on the data.

  In this manner, one or a plurality of usage and level-specific song data corresponding to a predetermined usage and level can be generated from one original song data based on the changed data, and even the same song can be generated. Since it is possible to reproduce musical tones with different reproduction modes according to usage and level, the user does not need to prepare song data corresponding to the usage and level in advance, so that the user can use the desired usage and level with a small amount of data. A wide variety of musical sounds can be played. Further, even when such original song data is mixedly stored with previously prepared use and level-specific song data, a plurality of music related to the same song with different reproduction modes according to the use and level are recorded for each song. In this way, the user can grasp in advance according to the display what kind of song data exists and what kind of usage and level of the musical tone according to the desired song is present. Therefore, it is possible to easily and quickly find and play a musical sound according to a desired application and level. Moreover, even if the above-mentioned display mode is the same song but there are a lot of song data with different uses and levels, it is advantageous that the display can be performed in a small display range.

The setting status of various settings relating to performance environment / musical sound control (including so-called registration), various data stored in the ROM 2 and the storage device 8, or the control status of the CPU 1 are displayed. The display 6A is, for example, a display capable of displaying a simple screen with few displays as shown in FIG. 7 to be described later, that is, the number of characters / symbols and the number of characters that can be displayed is limited. Any display device may be used as long as it is difficult to display data contents and the like, and the display area is narrow but the cost is low.

  The tone generator / effect circuit 7 can simultaneously generate musical tone signals in a plurality of channels, and is generated in response to a manual operation of the performance operator 4A by the user given via the data and address bus 1D. Alternatively, various performance information generated based on music data stored in advance is input, and a musical sound signal is generated based on the performance information. Furthermore, various acoustic effects are appropriately given to the generated musical sound signal. A musical 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., may be configured with dedicated hardware, or may be a DSP (Digital Signal Processor). ) Or software processing by the CPU 1.

  The storage device 8 has original song data (see FIG. 2) and change data (see FIG. 3), which will be described later, and various kinds of data prepared in advance such as song data according to usage and level (see FIG. 4). Various control programs executed by the CPU 1 are 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 execute the same operation as in FIG. 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.

  The communication interface (I / F) 9 is an interface for transmitting and receiving various information such as a control program and various data between the apparatus and an external device (not shown). 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 above-described embodiment, the performance operator 4A is not limited to a keyboard instrument, and may be any type such as a stringed instrument, a wind instrument, or a percussion instrument. Further, 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 a communication interface 9 such as a MIDI interface or various networks. Needless to say, the apparatus may be configured to connect the respective devices using the.

  Like the conventionally known electronic music apparatus, the electronic music apparatus according to the present invention can reproduce the musical sound based on the song data read from the ROM 2 or the storage device 8 according to the user selection. It has become. However, in the electronic music apparatus according to the present invention, when the read music data is music data according to use and level, the music data is reproduced as it is according to the music data, while the read music data Is original song data with change data (hereinafter referred to as original data for the sake of convenience), the change data corresponding to the use and level designated by the user is based on the original data. The music data is recreated into new song data (newly generated), and based on this, it is possible to reproduce the musical tone in a reproduction mode (reproduction mode suitable for the user's desired use and level) different from the original data. . This will be described below.

  First, original music data (original data) will be described. FIG. 2 is a conceptual diagram showing an embodiment of the data structure of the original data. As can be understood from FIG. 2, the original data can be roughly divided into a control part, a part dedicated to automatic performance, a part for user performance, and a guide voice part. The control part is data defining various settings (control data) related to performance environment / musical sound control that determines the playback mode in automatic performance, and the control data is used, for example, when reproducing the original data. Tempo data that defines the tempo (absolute value), effect data that defines an effect such as reverberation given when the original data is reproduced, and the like are defined.

  The automatic performance-dedicated part and the user performance-corresponding part are data used to automatically perform a predetermined music associated with the automatic performance part, and are recorded in a predetermined file format such as a known SMF (Standard Midi File). This is automatic performance data with a multi-part configuration. Of course, it is not limited to automatic performance data. Further, in this embodiment, an example is shown in which parts 1 to 10 are assigned to automatic performance-dedicated parts, and parts 11 to 15 are assigned to user performance-corresponding parts, but such assignment can be changed as appropriate. It's okay.

  The automatic performance-dedicated part is a part that is always played back regardless of whether the original data is selected for viewing or practice (except for voice guidance). There is a difference in that it is a part that is played when selected as an appreciation use but is not played when selected as a practice use (or voice guide use). In consideration of the above points, each of these parts includes all the music constituting the music such as a melody part related to a melody, an accompaniment part related to a bass or chord performance, a rhythm part related to a rhythm accompaniment, etc. Automatic performance data relating to any one of the parts is stored after being appropriately segmented. However, automatic performance data does not necessarily have to be stored in all parts 1 to 15. In other words, there may be an empty part in which no data is stored. The automatic performance data includes timing data representing the time for processing various event data for reproducing music such as pronunciation and mute, and event data representing the contents of various events for reproducing music such as pronunciation and mute It consists of a pair. The contents of various events include, for example, key-on, key-off, tempo change, tone color change, and automatic performance is performed based on these events.

  Unlike the automatic performance-dedicated part and the user performance-corresponding part as described above, the guide sound part stores audio data such as sound instead of automatic performance data. As an example, pre-recorded voices or sound effects such as those in which the melody part is uttered in the order of the scale sound (for example, Doremifasolaside) or the points to be noted during performance practice are stored, or these are stored. Is stored as event data.

The control data stored in the control part is not limited to tempo data and effect data, and other control data such as timbre data defining a timbre and volume data defining a volume may be stored. Further, the control data as described above is not limited to be stored in the control part, but may be stored in any one of the automatic performance dedicated part, the user performance corresponding part, and the guide voice part.
Further, a file name (for example, “KIRAKIRA.MID”) is given to the music data, and a unique ID, a music title, and the like are stored in a header area (not shown) of the music data.

  Next, change data used when displaying song data by use and level that can be generated based on the original data, and generating new song data based on the original data according to the use and level specified by the user Will be described with reference to FIG. FIG. 3 is a conceptual diagram showing an example of the data structure of the change data. However, a table-type management file that collectively manages change data of a plurality of original data is shown here as an example.

  As shown in FIG. 3, the change table includes at least song information, usage and level information (use / level information) and change information related to the original data, and uses and levels of change information for the original data by use and level. It is defined in association with information. The song information is information indicating (that is, identifying) to which original data the changed data is applied. For example, the song information file name (such as KIRAKIRA.MID) as shown in FIG. Information indicating the data is stored. The usage and level information is information indicating a combination of usage and level applied when the original data is changed into new music data corresponding to the usage and level. Here, as an example, for viewing / practice / voice guide The information is stored in any one of the combinations of the three usages and the three levels of beginner / intermediate / advanced level.

  The change information is one or more pieces of information for instructing the data change contents for the original data when generating new song data from the original data. For example, the change information is a relative tempo (100 to 10%, etc.) or a reverb return (100 to 10). Information related to various settings related to performance environment / musical sound control such as%) and information related to automatic performance data such as part on / off. According to this change information, the corresponding part of the original data is changed to data contents corresponding to the use and level, and is recreated (newly generated) as song data for each use and level (see FIG. 4 described later). Since the change data applicable to the original data is specified according to the song information and the usage and level information, if the user designates the usage and level in addition to the song selection, the song data for each usage and level is updated. Can be generated.

Note that the change information is not limited to that described above. Further, the usage and level information of the change data and the change information may be generated / changed appropriately by the user.
In the above-described embodiment, the management file is used to collectively manage change data. However, the present invention is not limited to this, and change data corresponding to a plurality of uses and levels is stored in advance in the control part for each original data. You may make it leave.

  Next, the use and level-specific music data stored in the ROM 2 or the storage device 8 in combination with the above-described original data will be described with reference to FIG. FIG. 4 is a conceptual diagram showing an example of the data structure of song data by use and level. FIG. 4 shows song data for viewing, song data for practice, and song data for voice guidance in order from the left in FIG.

  Each piece of music data shown in FIG. 4 is individually prepared and prepared in advance for each use and level so that a musical sound corresponding to the use and level can be reproduced. The music data for each use and level, such as for appreciation / practice / voice guidance, is divided into control parts, automatic performance dedicated parts, user performance compatible parts, and guide voice parts. However, different information is defined as data contents in each part corresponding to each use and level. This will be described below.

  The control part is data that defines at least information related to various settings related to performance environment / musical sound control that determines the playback mode during automatic performance, and defines tempo data that defines the tempo (absolute value), effects such as reverb, etc. Effect data is defined.

The contents of each data in the automatic performance dedicated part, the user performance compatible part, and the guide voice part are the same as the original data described above, and thus the description thereof is omitted here. However, as shown in FIG. 4, each piece of music data according to usage and level, such as appreciation, practice, and voice guide, has different data contents for the automatic performance part, the user performance corresponding part, and the guide voice part. . That is, as shown in FIG. 4A, no data is stored in the part 16 in the music data for viewing. Since the part 16 is a guide voice part as described above, when the song data is reproduced, the guide voice is omitted, but a musical sound including all the parts constituting the song is reproduced. As shown in FIG. 4B, the music data for practice is not stored in the parts 11-16. Since the part 16 is a guide voice part and the parts 11 to 15 are user performance parts, when the song data is reproduced, the guide voice and a part (user performance part) of all the parts constituting the song are omitted. Will be played. As shown in FIG. 4C, the music guide data for voice guidance is stored only in part 16. Therefore, when the music data is reproduced, only the guide voice is reproduced without reproducing the musical sound.
It should be noted that the automatic performance data is not stored in all parts other than the data “not stored”, that is, parts 1 to 15 in the music data for viewing and parts 1 to 10 in the music data for practice. There may be an empty part.

  In the music data described above, the control data defined in the control part is not limited to tempo, reverb return, etc., but other control data such as other effect data other than reverb, tone data defining tone color, volume data defining volume, etc. Data may be defined. Further, the control data as described above is not limited to be stored in the control part, but may be stored in any one of the automatic performance dedicated part, the user performance corresponding part, and the guide voice part.

  FIG. 5 is a conceptual diagram showing a specific example of the relationship between music data management data for each use and level and the control data value of each music data. The song number is information indicating an identification number (ID) unique to each song data, and is assigned in ascending order according to, for example, the order in which the song data is generated regardless of the use and level. The song information is information indicating each song data individually, and for example, a song data file name (such as KIRAKIRA_LIS_L3.MID) composed of a character string as shown in FIG. 5 is stored. The information on the use and level is information indicating what kind of use and level the musical sound that can be reproduced by the song data corresponds to. For example, there are three uses for appreciation / practice / voice guidance and beginners. / Intermediate / advanced information consisting of one of three combinations. In this embodiment, information on the usage and level is included in the character string of the music data file name. That is, the character string indicating the song data file name is a character string corresponding to each song name (for example, KIRAKIRA, ELISE, PATH, etc.), which corresponds to the song reproduced by the song data and is the same if it is the same song. Is combined with a character string (keyword) representing a use and a level associated with the use and the level in advance.

  The character string indicating the use and level indicates, for example, a character string “LIS” indicating that the song is for viewing, a character string “LES” indicating that it is for practice, and a voice guide. One of the character strings “GID”, the character string “L1” indicating that it is for beginners according to the user's performance level, the character string “L2” indicating that it is for intermediate users, and that it is for advanced users The character string “L3” shown is formed by being arranged and described. So, for example, if the song data file name is “ELISE_LIS_L1.MID”, the music for viewing (LIS) and for beginners (L1) for the specific song (for Elise) corresponding to the song data “ELISE” It is shown that the song data can be played, and if it is "PATH_LES_L2.MID", it is for practice (LES) and intermediate (L2) for a specific song (sorrow) corresponding to the song data "PATH" If it is “KIRAKIRA_GID_L2.MID”, it is indicated that the music data of the music can be played, and for a specific song corresponding to the song data “KIRAKIRA” This indicates that the song data is playable for intermediate (L2) music.

  Thus, in the present embodiment, unlike the above-described original data, the usage and level information is included in the file name of the song data for each usage and level, so that the original data and the song data for each usage and level are based on the file name. Can be distinguished from each other. That is, the data can be distinguished according to the use in the music data file name and the presence or absence of level information. Specifically, a song data file name having usage and level information is song data by usage and level, and a song data file name having no usage and level information is original data. Of course, the method for distinguishing the data is not limited to this. Needless to say, the character string added to the end of the music data file name is a character string indicating the data format / type of the music data (here, “MID” indicating a MIDI file). In addition, although the song data file name of the song information including the usage and level information is shown, the present invention is not limited to this, and the usage and level information may be defined separately from the song information.

  The song name is data indicating the name of the song to be reproduced by the song data. As described above, if the character string indicating the song data is the same in the song information, the song name is the same. On the right side of the management data, the relationship between the values of the control data stored and set in each piece of music data is shown. For example, regarding the song data “KIRAKIRA”, when the tempo and reverb values of the song data for viewing (001) are set to 100%, the values for the song data for practice (002) are 90% and 90%. It is 90% and 100% of the music data (005) for use. As described above, files having different uses and levels for the same music data are produced so that not only the configuration of each performance part is different but also the value of the control data is different.

  Next, on the basis of the original data (see FIG. 2) stored in the ROM 2 or the storage device 8 or the like and the music data according to the usage and level, the musical tone having different reproduction modes according to the usage and level that can be reproduced. Will be presented to the user, and the “main process” for reproducing the musical sound according to the user selection will be described. FIG. 6 is a flowchart illustrating an example of “main processing”. The process is started in response to, for example, an operation of a music selection start button by the user.

  In step S1, song data (original data, pre-prepared usage and song data for each level) stored in the ROM 2 or the storage device 8 in a mixed manner are sequentially acquired. In step S2, it is determined whether the acquired music data is original data or music data by use and level. This determination is performed, for example, based on the use in the file name and the presence / absence of level information as described above. When it is determined that the acquired music data is original data (YES in step S2), change data to be applied to the original data is acquired from the management file according to the music data file name or the like (step S3). However, if change data is stored in the original data, the change data may be acquired from the original data. In step S4, display information including usage / level information is added to the music selection list for song data by usage and level that can be newly created based on the acquired original data and change data.

  On the other hand, when it is determined that the acquired song data is song data by use and level (NO in step S2), use and level information is acquired from the song data (step S5). For example, in the case of the music data file name “KIRAKIRA_LIS_L1.MID”, “for viewing / beginner” is acquired as usage and level information. In step S6, display information including usage / level information is added to the music selection list based on the acquired original data and usage / level information. In step S7, it is determined whether or not the listing work from steps S1 to S6 described above has been completed for all music data mixedly stored in the ROM 2 or the storage device 8. If it is determined that the list work has not been completed for all song data (NO in step S7), the process returns to step S1 and the list work is continued.

  On the other hand, if it is determined that the listing work has been completed for all song data (YES in step S7), the “music selection list (screen)” in which the music selection list is reconfigured together with the same music title (see FIG. 7). Is created (step S8). As will be described in detail later, if there are a large number of songs by use and level that are created based on the original data and the change data or prepared in advance for each use and level for the same song, the plurality of song data are Rather than displaying each piece of music data individually, a music selection list (screen) is created that collectively displays the plurality of pieces of music data as song data related to the same song in song units (specifically, song names). In that case, common information such as specific music information defined in the song data or in the management file (for example, the song information file name “KIRAKIRA” (corresponding to the song name) and the song name “Kirakira star”), Of course, this is not a limitation, and it is determined whether or not the specific music information is song data related to the same song having the same content (song name here), and then the song related to the same song. Display data collectively. That is, it is classified for each piece of music data related to the same music according to specific information, and these are displayed together. In step S9, the created “music selection list (screen)” is displayed on the display 6A, thereby presenting to the user the music data by use and level that can be reproduced by the apparatus.

  Here, the “selection list screen” displayed on the display 6A in order to present reproducible usage and level-specific music data to the user will be described with reference to FIG. FIG. 7 is a conceptual diagram showing an example of a “selection list screen”. Here, the original data accompanied with the change data (see FIG. 2) and the song data by use and level (see FIG. 4) are mixedly stored, and the management data at that time is the data shown in FIG. 3 and FIG. A display example in the case of content is shown.

  A “selection list screen” A shown in FIG. 7 displays information on reproducible uses and music data by level in a predetermined display area B. Information on the song data for each usage and level includes song number C, song name D, usage and level information E as shown. Song number C is a number added in ascending order, for example, in order to distinguish reproducible songs by each piece of song data, and different numbers are assigned sequentially for each song (defined in the management data shown in FIG. 5). It is different from the song number). The song name D is the song name defined in the management data, that is, the name of the song to be played back by the song data. Even if the usage and level are different, the original data is changed by the change data, and the usage data and the level are changed. Information that can be used to generate music data related to the same song, whether it is a song data that is generated in advance or a song data that is prepared in advance for use and level. Music information).

  The usage and level information E is displayed in association with the song name D (common music information), and is included in the character string in the song data file name and usage and level information included in the song information defined in the management data. Display usage and level information. In the example shown here, the usage information is written as appreciation / practice / voice guide, while the level information is 1 star for beginners, 2 stars for intermediate, and advanced. Symbols are shown with three stars. In the electronic music apparatus according to the present invention, in order to display the usage and level information E, the usage and level information E can be stored in units of music if the same music is used even for a plurality of different usages and levels. Are collectively displayed in association with the song number C and the song title D. Furthermore, even if the original data is changed and the pieces of music data generated by use and level are mixed, the same music is presented together in units of music.

  For example, for the song name “Kirakira Hoshi”, three pieces of song data for viewing, beginner / practice, intermediate / voice guide, and beginner are prepared in advance (see FIG. 3) and the original data. 4 songs can be created for viewing, advanced / practicing, beginner / practice, advanced / voice guide, and intermediate (see FIG. 5). Seven different uses and level information E corresponding to the mixed music data are displayed in association with the music name D which is common music information as shown in the figure. For the song name “For Elise”, only one piece of music data for viewing / intermediate is prepared in advance (see FIG. 3), and only one piece of music data for viewing / beginner is prepared based on the original data. Since it can be generated (see FIG. 5), two uses and level information E are displayed in association with the song title D as shown. In addition, two pieces of music data for practice, beginner / practice, and advanced are prepared in advance for the song name “Sorrow” (see FIG. 3), and 1 for practice / intermediate based on the original data. Since only song data can be generated (see FIG. 5), three uses and level information E are displayed in association with the song name D as shown. When a plurality of uses and level information E, which are the same use, are displayed in association with the song title D, one of the same uses and level information E is displayed at a position parallel to the song title D, and the other is displayed in parallel. Displayed below the displayed usage and level information E. Moreover, even if it is a different use, if it is the same level, it displays in parallel.

  Then, the user selects a desired song number C or song name D using an operator such as an increment button, a decrement button, or an arrow button, for example, and then positions the cursor on the desired use and level information E. Then, by pressing the Enter button or by directly touching the desired application and level information E on the screen, it is possible to specify the music data for each application and level for which musical sound is desired to be reproduced.

  In this way, in the “selection list screen” A shown here, a plurality of different usages and level-specific song data are separately prepared for the same song, but each usage and level information E is provided to the user. Instead of displaying different song data separately, a plurality of related song data are displayed together for the same song.

  In the specification of the song data on the “selection list screen” A, when the song data is the original data, the use of the change data corresponding to the specified original data and the specification of the original data are substantially determined. It goes without saying that it is only the specification of level information. By doing so, the user can specify the song data by use and level for the desired song without being particularly aware of the original data.

  Returning to the description of FIG. 6, in step S10, the song name, usage, and level information displayed in the “music selection list (screen)” are selected by the user as described above, and the selected song name and usage are selected. And music data corresponding to the level are specified. In step S11, it is determined whether the specified music data is original data or music data by use and level. If it is determined that the data is original data (YES in step S11), the original data is changed based on the specified usage and level change information in the changed data associated with the specified original data. Then, music data is newly generated in accordance with the selected application and level (step S12).

  Step S13 reproduces a musical tone based on the specified music data or the generated music data. When playing a musical sound, it is played after making various settings according to control data such as tempo and reverb return stored in the control part.

  As described above, the electronic music apparatus according to the present invention collectively presents separate song data corresponding to a plurality of uses and levels related to the same song for each song. Also, one or more pieces of music data corresponding to the application and level are generated from one original data (original music data).

  Even when one piece of original data and one to a plurality of uses and song data for each level are mixed and stored for each song, a plurality of uses and levels related to the same song are based on these song data. The musical sounds having different reproduction modes are displayed together in a common music information unit (song unit). As a result, the user can quickly grasp what kind of song is present according to the display, and the user can grasp in advance according to the display what kind of use and level the musical sound is associated with the desired song. Therefore, it is very convenient that a musical sound corresponding to a desired application and level can be found and reproduced easily and quickly. As described above, in the electronic music apparatus according to the present invention, a user can reproduce a wide variety of musical sounds according to a desired use and level of a desired song by a simple operation.

  As mentioned above, although an example of embodiment was demonstrated based on drawing, this invention is not limited to this, It cannot be overemphasized that various embodiment is possible. For example, the user can arbitrarily designate a use or level in advance. In such a case, only song data relating to the designated use or level is selected and displayed on the “selection list screen”. It is good to. FIG. 8 is a conceptual diagram showing another embodiment of the music selection list screen.

  FIG. 8A shows an example of display when practice is selected as the application. Information related to the song data by usage and level displayed on the music selection list screen A is selected in addition to the song number C, song name D, usage and level information E displayed in the predetermined display area B as shown in the figure. Information F is added. Since the song number C and the song title D are as described above, the description thereof is omitted here. The selection information F is a newly added display, and displays the usage selected by the user (in this example, for practice). The usage and level information E displays the usage and level information included in the character string in the song information defined in the management data or the song data file name. Since it is already displayed in the information F, there is no description of the usage information by characters, symbols, or the like, and only the level information is indicated by characters (or symbols) for beginners, intermediates, and advanced users.

On the other hand, FIG.8 (b) shows the example of a display when for beginners is selected as a level. As for the information on the song data for each usage and level displayed on the music selection list screen A, the song number C, song name D, usage and level information E displayed in the predetermined display area B as shown in the figure are the same as when the usage is selected. In addition, selection information F is further added. The selection information F displays the level selected by the user (for beginners in this example). Regarding the usage and level information E, since the level information of the usage and level information is already displayed in the selection information F, the level information is not written in characters or symbols, and only the usage information is for viewing, practice, and voice guide. Character (or symbol) notation is used. In addition, in each song selection list screen shown in FIG. 8, even if the music is the same song, even if it is song data of a plurality of different levels (or usages), the usage information (or level information) is collectively displayed for each song. Of course. In FIG. 8 (a), three levels of information for each of the songs “Glitter Star” and “Sorrow” (beginner, intermediate, advanced), and in FIG. 8 (b), three pieces of usage information for the song “Glitter Star”. (Use for appreciation, practice, voice guide), one use information (for appreciation) about the song "For Elise", one use information (for exercise) about the song "Sorrow" is grouped in each song unit It is displayed.
In the embodiment described above, song data for each use and level are stored separately, and the original data can be changed to generate song data for each use and level. Although the list display is performed, the present invention is not limited to this, and the present invention may be applied to one that only stores song data for different uses and levels.
