Description

  The present invention relates to a music data reproducing apparatus and a music data reproducing method for selecting and reproducing music data.

  2. Description of the Related Art Music data playback apparatuses that select and play music data are conventionally known.

  There are a plurality of types of music data, and typical examples include song data and accompaniment style data. The song data is used to automatically play a piece of music by sequentially reproducing from the first performance data to the last performance data included in the song data. The accompaniment style data is composed of performance data of a predetermined length (for example, one bar length) corresponding to each of a plurality of sections (such as “intro”, “main”, “ending” and “fill-in”). This is used to generate accompaniment by repeatedly reproducing the performance data as appropriate.

  Song data and accompaniment style data are both data to be played back, but since the playback uses are different, the type of music data that the user intends to play when the play button is pressed, There is a case where it is desired to improve the operability of the user by matching the type of music data to be reproduced. In addition, various functions used when reproducing song data (hereinafter referred to as “song function”) and various functions used when reproducing accompaniment style data (hereinafter referred to as “style function”) are common or related. While there are other differences.

  Therefore, it goes without saying that there are different functions between the song function and the style function, and even if it is a common or related function, the operator for the song function and the operator for the style function are grouped separately for each function. There is an electronic musical instrument provided (for example, see Non-Patent Document 1).

  However, since this conventional electronic musical instrument is provided with other controls even if they have common or related functions, a large number of controls are arranged on the operation panel. While it is difficult to find a child, the manufacturing cost increases for the manufacturer due to the increase in the number of parts.

  Therefore, song mode and style mode are provided, and not only common functions between song functions and style functions, but also non-common functions are assigned to the same controller, and non-common functions can be switched by switching modes. There is also an electronic musical instrument that can be operated (see Non-Patent Document 2, for example). However, in this conventional electronic musical instrument, the button for selecting song data and the button for selecting accompaniment style data are provided separately, but there are still fewer operators than the former conventional electronic musical instrument. It has become.

  However, in the latter conventional electronic musical instrument, there is an operator whose function to be operated fluctuates depending on the mode. Therefore, if the user always grasps the current mode and does not operate the operator, the correct operation is performed. There was a case that could not be done.

  The present invention has been made paying attention to this point, and it is possible to select and reproduce different types of music data without hesitation while reducing the manufacturing cost by reducing the number of operators. An object of the present invention is to provide a program for realizing the music data reproducing apparatus and the music data reproducing method.

In order to achieve the above object, the music data reproducing device according to claim 1 stores a storage unit that stores a unique data ID that is associated with each of a plurality of types of music data, regardless of the type of music data, In accordance with the designated data ID, designation means for designating one of a plurality of data IDs stored in the storage means, reproduction means for reproducing music data corresponding to the data ID designated by the designation means, Te, wherein the reproduction setting of reproduction means have a control means for controlling to switch to suits reproduction setting the type of music data corresponding to the specified data ID, the multiple kinds of music data, melody A first type of music data consisting of a plurality of parts including a part and a pattern of a predetermined length consisting of one or a plurality of accompaniment parts for repeat playback When the first type of music data is designated, the control means switches to the first reproduction setting for reproducing the first type of music data from the beginning to the end. On the other hand, when the second type of music data is designated, control is performed so that the second type of music data is switched to a second playback setting for repeated playback .

Note that the music data reproducing apparatus according to claim 1, may be provided with a display means for displaying the correlated et al data ID of the music data.

The music data reproducing device according to claim 2 further comprises selection instruction means for instructing selection of a data ID at a default position in the music data reproducing apparatus according to claim 1 , wherein selection instruction by the selection instruction means is made. , the control unit may be the same type of music data and the music data corresponding to the data ID that is currently designated by said designation means and you to select the music data in the default position.
According to a third aspect of the present invention, there is provided the music data reproducing apparatus according to the second aspect, wherein when the selection instruction is given by the selection instruction means, the control means uses the data ID currently designated by the designation means. The music data of the same type as the music data corresponding to the data data, and the data ID of the music data at the default position is displayed on the display unit.

The music data reproducing device according to claim 4 further includes a mute instruction means for instructing to mute a part of the music data in the music data reproducing device according to any one of claims 1 to 3. The second type of music data includes music data composed of a plurality of parts including a rhythm part having no pitch and an accompaniment part that is pronounced at a pitch corresponding to the pitch of the performance sound played by the user, If the first type of music data is specified when the mute instruction is given by the mute instruction unit, the control unit mutes the melody part of the first type of music data, and When two types of music data are designated, the accompaniment part of the second type of music data is muted.

  In order to achieve the above object, the program according to claim 6 can be realized by the same technical idea as that of claim 1.

  According to the first or sixth aspect of the invention, since different types of music data can be designated and selected by one designation means, an operator for selecting music data is separately provided for each type of music data. Or a mode switch is not required for the user to switch modes. As a result, the number of operation elements can be reduced to reduce the manufacturing cost, and the discriminability for the user operation elements can be improved.

Further, since the music data playback setting is switched to the playback setting corresponding to the type of music data corresponding to the specified data ID in accordance with the specified data ID , the user designates the data ID. The music data of the instructed data ID can be immediately reproduced with an appropriate reproduction setting simply by instructing the reproduction. Thereby, the user operability is further improved.

  If the data ID specified by the specifying means is provided in the invention according to claim 1 or 6, visual feedback is made when the data ID is specified. Since the operation becomes easier and the currently designated data ID can be confirmed, the currently designated music data (type) can be estimated. Here, as a specific example of how it can be estimated, for example, when music data in FIG. 3 to be described later can be specified, if the data ID is “0001”, the music data of the first song is If the data ID is a young number, it may be “song data”.

According to the second aspect of the present invention, when the selection instruction is given by the selection instruction means, the music data is the same type as the type of the music data corresponding to the currently specified data ID, and the default position since so as to select the music data in, the user grasps the type of music data currently selected, without re-select music data default position, by a simple operation, immediately the intention Music data can be selected. Thereby, the user operability is further improved.

According to the fourth aspect of the present invention, when the first type of music data is specified when the mute instruction is given by the mute instruction means, the melody part of the first type of music data is muted. When the second type of music data is designated, the accompaniment part of the second type of music data is muted. That is, since a mode is not provided for each type of music data, a function that is common or related to different types of music data is assigned to one operator, and the function can be performed by one operator. Even if the user always knows the current mode and does not operate the operation element, the user can perform the intended operation without hesitation. Thereby, the operability of the user's function selection is further improved.

Furthermore, the present invention can be applied not only to electronic musical instruments but also to electronic devices such as karaoke equipment, game equipment, and communication equipment.

  FIG. 2 is a plan view showing a part of the panel surface of the music data reproducing apparatus of the present embodiment. A part of the panel surface includes a numeric keypad 21, a + (plus) button 22, a-(minus) button 23, a START / STOP button 24, and a TEMPO button 25, as shown in FIG. , A MUTE button 26, a PAUSE / FILL button 27, and a 7-segment LED 8a (hereinafter abbreviated as “LED 8a”). The buttons 21 to 27 belong to the setting operator 2, and the LED 8 a belongs to the display unit 8.

  In the present embodiment, the numeric keypad 21 is used when selecting music data to be reproduced. As will be described later with reference to FIG. 3, each music data is given a unique data ID (a three-digit number in the present embodiment). By inputting a number, music data to be played can be directly selected. The input number is displayed on the LED 8a, but there may be no music data corresponding to the input number. In this case, music data is not selected, and the LED 8a is displayed before the number is input. Return to the state. Alternatively, an error display (for example, “---”) may be issued to prompt the user to input a correct data ID.

  When the music data has already been selected, that is, when a valid number is displayed on the LED 8a, the user presses the + button 22 or the-button 23 to increase or decrease the displayed number. You can also select the music data you want to play. This selection function is assigned to a dial switch (not shown) instead of the + button 22 and the − button 23, and the displayed number is changed in response to the user rotating the dial switch, for example, clockwise or counterclockwise. The music data to be reproduced may be selected by increasing or decreasing.

  The START / STOP button 24 is used to instruct start / stop of reproduction of the music data being selected.

  The TEMPO button 25 sets the tempo of the music data being selected in cooperation with the numeric keypad 21 or the + button 22 and / or the-button 23. Specifically, when the user operates the numeric keypad 21, the + button 22 or the-button 23 within a predetermined time after pressing the TEMPO button 25, the tempo value input with the numeric keypad 21, the + button 22 or the-button 23 is displayed. The tempo value increased / decreased by is set. Also, if the user simultaneously presses the + button 22 and the − button 23 within a predetermined time after pressing the TEMPO button 25, the currently set tempo becomes a unique tempo (provided in advance in the selected music data). The initial tempo is reset.

  The MUTE button 26 is used to toggle between mute (mute) and release of a part of the music data being selected. This part is determined in advance according to the type of music data being selected. Specifically, if the music data being selected is song data, the melody part (part 1 (see FIG. 3 in this embodiment)) is muted, and if it is accompaniment style data, the accompaniment part (this embodiment) In the form, parts 3 to 8 (see FIG. 3) are muted.

  The PAUSE / FILL button 27 is for instructing to pause the song data during reproduction, and for reproducing the fill-in section performance data during reproduction of the accompaniment style data.

  In this embodiment, the 7-segment LED 8a is used as a display for displaying the 3-digit number of the music data. However, the present invention is not limited to this. You may employ | adopt the thing of a system. In addition, the music data reproducing apparatus according to the present embodiment assumes that the display 8 includes a small LCD (not shown) or LED for displaying other information in addition to the LED 8a. Not only this but the indicator 8 is good also as only LED8a.

  FIG. 3 is a diagram showing an example of music data stored in the storage device 9 and its format. As shown in the figure, the storage device 9 stores in advance 15 pieces of song data # 1 to # 15 and 20 types of accompaniment style data # 1 to # 20 as music data. As the format of each music data, in the present embodiment, for convenience of explanation, SMF (standard MIDI file) format MIDI data is adopted. Of course, MIDI data in other formats may be adopted, or other formats that do not adopt the MIDI format, for example, performance information such as OSC (Open Sound Control) may be used. Further, the audio track (part) may be included, or the audio track (part) may be included.

  As described above, when the user selects any music data using the numeric keypad 21, the + button 22 or the-button 23, the selected music data, that is, song data or accompaniment style data is read from the storage device 9. And stored in a music data storage area (not shown) secured at a predetermined position in the RAM 7. The storage location of the song data and the accompaniment style data is not limited to the storage device 9 but may be the ROM 6 or the RAM 7, and the storage location may be different between the song data and the accompaniment style data.

  As described above, a unique three-digit number (data ID) is assigned to each of the song data and the accompaniment style data. In the illustrated example, “001” to “015” are assigned to song data # 1 to # 15, and “016” to “035” are assigned to accompaniment style data # 1 to # 20. As described above, the unique numbers are assigned serial numbers from the first song data # 1 to the last accompaniment style data # 20. However, the number is not limited to this, and may be omitted. Of course, even if a number with no omission is given, not all three-digit numbers are filled, so when the user inputs a number using the numeric keypad 21, music data that is not stored is selected and instructed. Sometimes. In this case, as described above, the music data instructed to be selected is not selected. On the other hand, when the user selects music data using the + button 22 or the-button 23, the music data is selected one by one according to the arrangement order even if there is a missing unique number. When the user presses the + button 22 with the tail accompaniment style data # 20 selected, the music data to be selected moves from the tail accompaniment style data # 20 to the top song data # 1, and the top song When the-button 23 is pressed while the data # 1 is selected, the music data to be selected moves from the first song data # 1 to the last accompaniment style data # 20.

  Since each song data is configured in the same format, only the format of the song data # 1 is shown in FIG. The song data # 1 is composed of performance data 31 and metadata 32. The performance data 31 is composed of performance data of a plurality of parts (for example, 16 parts). The performance data of each part is a set of note event data including data such as note on / off, note number and velocity, event data such as pitch bend data and volume data, and timing data indicating the reproduction timing of the event data. And end data is added to the end of the sequence. In the present embodiment, part 1 is a melody part, and the other parts are accompaniment parts. On the other hand, the metadata 32 includes a song title, (initial) tempo, time signature, lyrics, and the like.

  When a certain piece of song data is selected, the entire song data is read from the storage device 9 and stored in the music data storage area. Subsequently, the tempo in the metadata included in the song data in the music data storage area is read out, and the setting unit of the sequencer 104 (details will be described later with reference to FIG. 4) as the initial value of the playback tempo. 104b is set.

  Since each accompaniment style data is also configured in the same format, only the format of accompaniment style data # 1 is shown in FIG. The accompaniment style data # 1 includes performance data 33 for the main section, performance data 34 for the fill-in section, and metadata 35. The performance data 33 of the main section and the performance data 34 of the fill-in section are composed of performance data of a plurality of parts (for example, 8 parts). The part changes the pitch to generate a percussion instrument sound (rhythm) that does not change the pitch (RHY part) and the accompaniment sound with various decorative sounds in conjunction with the rhythm. There is a part (ACMP (accompaniment) part). In the illustrated example, two parts 1 and 2 are provided as RHY parts, and six parts 3 to 8 are provided as ACMP parts. However, the number of parts is not limited to this. The number of parts of the performance data 33 of the main section and the performance data 34 of the fill-in section is 8 in this embodiment, but the number of parts is not limited to this. The number of parts may be different in the fill-in section. In addition to the main section and the fill-in section, there may be other sections such as an intro section, an ending section, a break section, and a plurality of types of main sections. The contents (format) of the performance data of each part of the performance data 34, 35 are the same as the contents (format) of the performance data of each part of the song data 31, and therefore the description thereof will not be repeated. On the other hand, the metadata 35 includes (initial) tempo and code conversion data. The chord conversion data is data for converting the pitch of the ACMP part of each section according to the user's key depression on the keyboard. This chord conversion data is a known one in this embodiment, and the pitch conversion of the ACMP part is generally performed using this known chord conversion data. A description of what the data is, how to use the chord conversion data, and how to convert the pitch of the ACMP part is omitted.

  When one piece of accompaniment style data is selected, the entire accompaniment style data is read from the storage device 9 and stored in the music data storage area, as in the case where song data is selected. However, unlike when song data is selected, the tempo in the metadata included in the stored accompaniment style data is not normally read, and the tempo setting of the setting unit 104b of the sequencer 104 does not change. Details of this will be described later.

  FIG. 4 is a block diagram showing a functional configuration of the music data reproducing apparatus according to the present embodiment. As shown in the figure, the music data reproducing apparatus of the present embodiment includes a performance operation unit 101, a setting operation unit 102, a control unit 103, a sequencer 104, a storage unit 105, a display unit 106, a sound source unit 107, and an output unit 108. It is constituted by.

  The performance operation unit 101 includes a performance operator 1 (particularly a keyboard) and a detection circuit 3, and the setting operation unit 102 includes a setting operator 2 (particularly the buttons 21 to 27 in FIG. 2) and the detection circuit 4. Consists of.

  The control unit 103 is mainly configured by the CPU 5, the ROM 6, and the RAM 7, and is realized by the CPU 5 executing control processes including the processes of FIGS.

  The sequencer 104 is also mainly composed of the CPU 5, the ROM 6 and the RAM 7, and is realized by the CPU 5 executing a sequencer program (not shown). The sequencer 104 includes a playback unit 104a and a setting unit 104b, and the playback unit 104a plays back the performance data included in the selected music data. At that time, the playback unit 104a plays back the performance data at the tempo set in the setting unit 104b. The tempo value set in the setting unit 104b can be changed as described above.

  The storage unit 105 includes the storage device 9 and stores a plurality of music data. As described above with reference to FIG. 3, there are two types of music data, song data and accompaniment style data. Each music data is given a unique data ID, that is, a three-digit number. The data ID may be included in each music data, or may be managed by a table or the like separately from each music data. In short, as long as the data ID and each music data are associated with each other in one-to-one manner, the data ID can be held in any way. Also, since the contents (data format) of each music data have been described above, they will not be repeated any more.

  The display unit 106 corresponds to the display 8 (in particular, the LED 8a in FIG. 2), and displays the data ID of the selected music data.

  The sound source unit 107 corresponds to the sound source / effect circuit 11 and converts the performance data output by the sequencer 104 reproducing and outputting music data, the performance data input by the user from the performance operation unit 101, and the like into musical sound signals. Appropriate effects are applied to the musical sound signal.

  The output unit 108 corresponds to the sound system 12 and converts the musical sound signal supplied from the sound source unit 107 into sound. In the present embodiment, the sound is generated from the speaker. However, the present invention is not limited to this, and the sound may be generated from the headphone (speaker).

  A control process executed by the music data reproducing apparatus configured as described above will be described in detail with reference to FIGS.

The music data playback device of this embodiment is
(1) Music data selection processing in which different types of music data (data IDs) can be selected with a common operator;
(2) When new music data (data ID) is selected by the music data selection process of (1) above, and the currently selected music data is changed to the newly selected music data, the change is made. Data ID change post-processing that automatically sets the sequencer 104 (the setting unit 104b) so as to perform (appropriate) reproduction according to the type of the music data;
(3) A playback control function that is a playback control function that is common or related between different types of music data, but that performs playback control processing with different contents every time the type of music data is different, by operating instructions using a common operator;
(4) A default music data selection process capable of selecting music data at a different default position for each type of music data currently selected according to an operation instruction by a predetermined operator;
Various control processes including are executed.

  For example, when the user turns on a power switch (not shown) of the music data playback device of the present embodiment, power is supplied to the music data playback device of the present embodiment. As a result, the music data reproducing apparatus of the present embodiment is activated, the music data selected at the end of the previous activation is selected as it is, and the data ID (three-digit number) is displayed on the display unit 106 (in FIG. 2). LED8a). If there is no previously selected music data, such as when the music data playback device of this embodiment is purchased and activated for the first time, the music data defined as the initial setting (for example, the first music data, that is, FIG. 3). Then, song data # 1) is selected.

  Now, as shown in FIG. 2, it is assumed that song data # 1 having a data ID “001” is selected. In this state, for example, when the user presses the + button 22, the music data selection process (1) is started, and the control unit 103 is positioned in the increasing direction by the number of times the + button 22 is pressed from “001”. Select the music data of the data ID to be used. As described above with reference to FIG. 3, 35 pieces of music data having data IDs “001” to “035” are stored in the storage unit 105, so that the user presses the + button 22 15 times, for example. Then, the music data with the data ID “016”, that is, accompaniment style data # 1, is selected, and the data ID “016” is displayed on the display unit 106. As described above, if there is a missing data ID (unique number) from the first music data (song data # 1 in FIG. 3) to the last music data (accompaniment style data # 20 in FIG. 3), The number of operations of the + button 22 may not correspond to the difference between the data ID before selection and the data ID after selection. Music data can also be selected by operating the − button 23 or the numeric keypad 21 in addition to the + button 22. This is also as described above.

  When the music data (data ID) is changed in this way, the control unit 103 reads the changed music data from the storage unit 105 and stores it in the music data storage area on the RAM 7. Then, the control unit 103 activates the data ID post-change process (2).

FIG. 5 is a flowchart showing the procedure of the post-data ID change process. In the figure, the control unit 103 determines the type of music data after the change, that is, the type of music data stored in the music data storage area (step S1). Here, as a method for determining the type of music data, any method may be used as long as the type of music data can be determined. For example, the following method is conceivable. That is,
(11) A method of preparing a table for associating a data ID with a type of music data in advance, and when the music data is changed, searching the table based on the data ID to determine the type of the music data;
(12) Since each music data is stored in the file format in the present embodiment as described above, the extension is described so as to be different for each type of music data, and the music data is indicated by the extension. How to determine the type of
(13) Structure of music data (specifically, song data includes only one piece of performance data consisting of a plurality of parts, whereas accompaniment style data includes a plurality of pieces of performance data consisting of a plurality of parts (in this embodiment, 2) including), and determining the type of music data from the analysis result;
(14) A method of determining the type of music data by describing the type of the music data in the metadata of each music data and reading it out;
Etc.

  If the result of determination in step S1 is that the music data has been changed to a different type (format), the control unit 103 instructs the sequencer 104 to switch the playback setting of the setting unit 104b (step S2 → S3). . On the other hand, when the music data is changed to the same type (format), the control unit 103 ends the post-data ID change processing.

  When the music data is changed from the song data to the accompaniment style data, since the music data is changed to a different type of music data, the control unit 103 instructs the sequencer 104 to match the setting unit 104b with the accompaniment style data. Change to settings. Specifically, the control unit 103 instructs to set repeat playback to ON.

  On the other hand, when the music data is changed from the accompaniment style data to the song data, since the music data is also changed to a different type of music data in this case, the control unit 103 instructs the sequencer 104 to set the setting unit 104b to the song data. Change the setting to match the data. Specifically, the control unit 103 turns off repeat playback, and turns on chain playback (the function to automatically read and play the next song data when playback of the song data for one song is completed). To set to.

When the data ID is changed, the tempo setting of the setting unit 104b is performed as follows by a process (not shown) different from the process of step S3. That is,
(21) When the song data is changed to another song data: the song data is changed to a tempo value in another song data;
(22) When changed from song data to accompaniment style data: changed to tempo value in accompaniment style data;
(23) When accompaniment style data is changed to song data: changed to tempo value in song data;
(24) When the accompaniment style data is changed to another accompaniment style data: the tempo value is not changed;
It is. In the case of (24), the tempo setting of the setting unit 104b is not changed because the accompaniment style data is basically reproduced at the tempo specified by the user. On the other hand, in the case of (22), the tempo setting of the setting unit 104b is changed because there is no tempo for reproducing accompaniment style data specified by the user at the time of change.

  When the user presses the START / STOP button 24 in such a state that certain music data is selected and playback suitable for the music data is performed, the playback unit of the sequencer 104 104a performs reproduction according to the music data in accordance with the setting of the setting unit 104b. Hereinafter, each playback process executed by the playback unit 104a when song data # 1 and accompaniment style data # 1 are selected as music data will be described in detail.

  First, when playback start is instructed while song data # 1 is selected, the playback unit 104a starts the performance data 31 (see FIG. 3) of song data # 1 stored in the music data storage area. Read data for each part. The head data of each part is not necessarily timing data, but here is timing data. The playback unit 104a decrements the timing data value of each part by “1” for each time corresponding to the tempo value set in the setting unit 104b. In the present embodiment, this decrement process is performed during a timer interrupt process (not shown). The timer interrupt processing is started in response to the rising edge (or falling edge) of the clock, and the playback unit 104a (CPU 5) sets the period corresponding to the tempo in the timer 13 (see FIG. 1). When the start is instructed, it is generated by the timer 13. As a result, the value of the timing data of each part is decremented by “1” every time corresponding to the tempo value set in the setting unit 104b.

  When the decrement advances and the value of the timing data of a part becomes “0”, the playback unit 104a reads the event data paired with the timing data for the part, and performs musical tone processing according to the content of the event data To the sound source unit 107. Since the performance data positioned next to the event data (there may be a plurality of event data) is the next set of timing data, the reproduction unit 104a reads the timing data and similarly decrements every predetermined time. Do. The reproducing unit 104a performs such processing for each part until the end data is read. When the last end data in all the parts is read, the reproducing unit 104a stops reproducing the song data # 1. Of course, if the user presses the START / STOP button 24 before the last end data in all parts is read, the control unit 103 immediately instructs the sequencer 104 to stop reproduction. In response to this, the playback unit 104a stops playback of the song data # 1.

  If the user presses the PAUSE / FILL button 27 while the playback unit 104a is playing back song data # 1, the control unit 103 activates the playback control process (3) and Instruct to pause playback. In response to this, the playback unit 104a pauses playback of the song data # 1. On the other hand, when the user presses the PAUSE / FILL button 27 again while the reproduction of the song data # 1 is paused, the control unit 103 immediately instructs the sequencer 104 to cancel the pause. In response to this, the playback unit 104a cancels the pause state of the song data # 1, and resumes the playback of the song data # 1 from the paused position.

  When the user presses the MUTE button 26 while the playback unit 104a is playing back song data # 1, the control unit 103 activates the playback control process of (3), and this (3) playback The process proceeds to the mute setting switching process included in the control process. FIG. 6 is a flowchart showing the procedure of the mute setting switching process. In the figure, since the currently selected music data is song data # 1, the control unit 103 instructs the setting unit 104b of the sequencer 104 to mute on part 1 of the performance data 31 of the song data # 1. (Step S11 → S12). As a result, since the mute on is set in the setting unit 104b, the playback unit 104a thereafter reads out the event data that produces a musical sound while playing the performance data of part 1, and the sound source unit 107 does not instruct the pronunciation. As a result, only the musical sound of part 1 is muted and only part 1 is muted. In this embodiment, as described above, a melody part is assigned to part 1 of the song data. Therefore, when only part 1 is muted, the user plays back the accompaniment parts (parts 2 to 16). At the same time, it can be used to play only the melody.

  On the other hand, when the user presses the MUTE button 26 while the part 1 is muted, the control unit 103 instructs the setting unit 104b of the sequencer 104 to mute off (step S12). As a result, the mute-off is set in the setting unit 104b. Thereafter, the playback unit 104a also reads out the event data for generating a musical tone for the part 1 as with the other parts. 107 is instructed to pronounce it. As a result, the muting of part 1 is released.

  Next, when playback start is instructed while accompaniment style data # 1 is selected, the playback unit 104a performs performance data 33 (in the main section of the accompaniment style data # 1 stored in the music data storage area). 3) is read out for each part. The reproduction method of the timing data and event data of each set included in the performance data 33 is almost the same as that of the timing data and event data of each set included in the performance data 31 of the song data # 1, so the details of the reproduction method The detailed explanation is omitted. However, as described above, when the user presses the keyboard during playback of the accompaniment style data # 1, the playback unit 104a uses the pitch of the key pressing sound and the chord conversion data 35b (see FIG. 4). Thus, the note number of the read event data is converted in the performance data of the ACMP part (parts 3 to 8 in the performance data 33 of FIG. 3). This control is performed in the same manner in the reproduction process of the performance data 34 in the fill-in section.

  When the playback process for the performance data 33 in the main section proceeds and the last end data of all the parts is read, the repeater 104a is set on the repeater 104a because the setting unit 104b is set to ON as described above. Returning to the beginning of the performance data 33 again, the reproduction of the performance data 33 is continued.

  When the user presses the PAUSE / FILL button 27 while the playback unit 104a is playing back the performance data 33 of the main section, the control unit 103 activates the playback control process (3) and Instruct to change the playback target. In response to this, the playback unit 104a changes the playback target from the current performance data 33 of the main section to the performance data 34 of the fill-in section. Then, the playback unit 104a executes a playback process similar to the playback process for the performance data 33 of the main section for the performance data 34 of the fill-in section. Since the performance data 34 in the fill-in section is reproduced only once in this embodiment (of course, this number is not limited to one), the last end data of all the parts of the performance data 34 in the fill-in section is stored. When read, the playback unit 104a automatically changes the playback target from the performance data 34 of the current fill-in section to the performance data 33 of the main section. In this way, the playback mode in which the playback of the performance data 34 of the fill-in section is appropriately inserted while the performance data 33 of the main section is being repeatedly played back is continued. When the user wants to stop the reproduction of the accompaniment style data # 1, the user presses the START / STOP button 24.

  If the user presses the MUTE button 26 while the playback unit 104a is playing back the accompaniment style data # 1, the control unit 103 activates the playback control process (3), and the mute setting shown in FIG. The process proceeds to the switching process. In the figure, since the currently selected music data is accompaniment style data # 1, the control unit 103 instructs the sequencer 104 to mute on the ACMP part of the performance data 33 or 34 of the accompaniment style data # 1. (Step S11 → S13). As a result, since the mute on is set in the setting unit 104b, the reproduction unit 104a thereafter reads out the event data that produces a musical sound while reproducing the performance data of the ACMP part. 107 does not instruct the pronunciation. As a result, only the tone of the ACMP part is muted and only the ACMP part is muted. When only the ACMP part is muted, only the RHY part is played back, which is convenient when the user wants to use percussion instrument sound instead of the metronome.

  On the other hand, when the user presses the MUTE button 26 while the ACMP part is muted, the control unit 103 instructs the sequencer 104 to mute off (step S13). As a result, the mute-off is set in the setting unit 104b. Henceforth, the playback unit 104a also reads out the event data for generating a musical tone for the ACMP part as in the RHY part. Is instructed to pronounce it. As a result, the ACMP part is unmuted.

  In the present embodiment, the example in which the mute setting switching process of FIG. 6 is executed during the reproduction of music data has been described. However, the mute setting switching process is executed before reproduction of music data, and after mute on / off is switched, Music data can also be played with the mute setting.

  After the processes (1) to (3) are executed as described above and various song data and various accompaniment style data are reproduced, the same type as the music data at the default position, particularly the currently selected music data. You may want to re-select the music data at the default location. For example, when various accompaniment style data are reproduced and asked for trial, it is preferable that the accompaniment style data is selected again and replayed because the one that was reproduced first was good. In this case, since the first accompaniment style data has a data ID that is not the first, that is, “001”, the user may not know which accompaniment style data is the first. In order to cope with such a situation, in the music data reproducing apparatus of the present embodiment, when the user simultaneously presses the + button 22 and the − button 23, the music data of the same type as the currently selected music data is stored. The one in the default position is now selected immediately. Although the default position is not necessarily the beginning of each type of music data, in the present embodiment, the music data at the default position is song data # 1 in the case of song data, and the accompaniment style data In this case, it is assumed that the accompaniment style data is # 1.

  If the user simultaneously presses the + button 22 and the − button 23 while the reproduction of music data is stopped, the control unit 103 activates the default music data selection process (4). FIG. 7 is a flowchart showing the procedure of the default data selection process. In the figure, when the currently selected music data is song data, the control unit 103 reads the song data at the default position, in this embodiment, song data # 1 (steps S21 → S22), and the song The data ID corresponding to the data is displayed on the display unit 106, that is, the LED 8a (step S23). As a result, “001” is displayed on the LED 8a. On the other hand, if the currently selected music data is accompaniment style data, the control unit 103 reads accompaniment style data at the default position, which is accompaniment style data # 1 in this embodiment (steps S21 → S24). The data ID corresponding to the accompaniment style data is displayed on the LED 8a (step S25). Thereby, “016” is displayed on the LED 8a.

  As described above, in the music data playback device of the present embodiment, a function common to or related to different types of music data is assigned to one operator without providing a mode for each type of music data. Since the operation can be performed with one operator regardless of the type of music data, the user does not hesitate to operate as intended even if the user always knows the current mode and does not operate the operator. Can be done. Thereby, the operability of the user's function selection is improved.

  In addition, since music data can be selected with a common operator regardless of the type of music data, a separate operator for selecting music data is provided for each type of music data, or a mode switch is provided. The user does not need to switch modes. As a result, the number of operation elements can be reduced to reduce the manufacturing cost, and the discriminability for the user operation elements can be improved.

  Further, when the music data is changed, the sequencer 104 (the setting unit 104b) is set so that the sequencer 104 (the reproducing unit 104a) can perform (appropriate) reproduction according to the changed music data. Is automatically set, the user can immediately play the changed music data by simply pressing the START / STOP button 24 after changing the music data. Thereby, the user operability is further improved.

  In addition, since the user presses the + button 22 and the − button 23 at the same time, the music data of the same type as the currently selected music data can be selected at the default position. By grasping the type of music data being selected and re-selecting music data at the default position, it is possible to immediately select the music data as intended by a simple operation. Thereby, the user operability is further improved.

  In the present embodiment, the two types of music data, song data and accompaniment style data, have been described as examples. However, the type of music data is not limited to this, and for example, Arpeggio, phrase data, or audio data may be used. The number of types of music data that can be selected is not limited to two, but may be three or more, or three or more types of music data may be selected without distinction.

  In this embodiment, two types of accompaniment style data sections, the main section and fill-in section, have been described as examples. However, other sections such as an intro section and an ending section are added to these sections. You may comprise so that the performance data of a section can be selected suitably and can be reproduced | regenerated.

  Furthermore, although the present embodiment does not mention the pitch change of the song data, the song data may be configured to be transposed.
