Description

  The present invention relates to a score display apparatus and a program for displaying a score of a song in a plurality of stages on a display screen based on predetermined song data. In particular, the predetermined song range including the performance position being played (playing back) is “current”, the predetermined song range that has been played immediately before “current” is “past”, and “current” is continued. A musical score display apparatus and program for displaying each musical score with a predetermined musical range to be played as “future” or the like while appropriately changing the display mode for each musical song range according to the progress of the musical piece About.

2. Description of the Related Art Conventionally, there are known a score display device and a score display program for displaying a score of a corresponding song in a plurality of stages for each predetermined range on a display screen based on song data such as automatic performance data and score display data. . As an example of such a method, there is a method or apparatus described in Patent Document 1 or Patent Document 2 shown below. In the method described in Patent Document 1, a musical score is displayed for each predetermined range separately in a two-stage musical score display area of an upper area and a lower area of the display screen. The musical score being played and the musical score just before the performance has been completed can be displayed separately on the display screen. Further, in the apparatus described in Patent Document 2, the display screen is similarly divided into two score display areas in the upper and lower areas, and includes a currently focused measure that is being played (playing back) 1 When a plurality of musical scores are displayed in the lower area, one or a plurality of musical scores to be played subsequent to the last musical score displayed in the lower area is displayed in the upper area. On the other hand, if a score including the currently focused measure that is currently being played (playing) is displayed in the upper area, you should continue to play the last score displayed in the upper area in the lower area. Display one or more music scores. By doing this, it is possible to check the score after the currently focused score that is being played (playing back) without interrupting the score in the middle of the song. In some cases, the current section of interest is highlighted as a whole measure).
Japanese Patent Publication No. 01-049956 JP 2001-265325 A

  As described above, the display screen is conventionally divided into two upper and lower score display areas, and the currently focused score that is being played (playing) and the score that has already been played are displayed on the display screen. Are displayed separately in each stage (score display area), or the currently focused score that is being played (playing back) and the subsequent score are displayed on each stage (score display area). For example, a past score that has already been played or a future score that will be played is displayed at the same time as the currently focused score. However, in the past, it has not been considered at all to display the past and future musical scores at the same time together with the musical score currently focused on, which is very inconvenient for the user. Therefore, it has been desired to provide a musical score display device and a musical score display program capable of simultaneously displaying all present, past and future musical scores on a display screen. In addition, conventionally, a part of a musical score currently focused on, such as a part being played (playing back), is clearly displayed by displaying it in a predetermined display form. As far as the screen display is concerned, it is unclear as to which position the score display is changed in accordance with the progress of the performance, and it is difficult for the user to understand.

  The present invention has been made in view of the above points, and when a score of a song is displayed in a plurality of stages on a display screen based on predetermined song data, the score currently being played (played) is focused on. "Present" is the score that has already been played immediately before "Present", and "Future" is the score that is played after "Present". Thus, it is intended to provide a musical score display apparatus and a musical score display program that allow a user to easily check each musical score of “current”, “past”, and “future” from the screen display. .

The score display apparatus according to the present invention includes an acquisition means for acquiring song data, a display means for displaying a score over a plurality of stages based on the acquired song data, and a current performance position on the score as the performance progresses And detecting means for displaying each score of the plurality of stages displayed according to the detected current performance position, a current score that is being played at least including the current performance position, a past score that has already been played, and a current score that is being played And a control means for controlling the display so as to display a combination of future musical scores that are subsequently played.
As a preferred embodiment of the present invention, the control means performs control so that at least the current score and the past score, or the current score and the future score are displayed in different display modes.

  According to the present invention, when a score is displayed over a plurality of stages based on the acquired music data, the current performance position on the score is detected as the performance progresses. Then, according to the detected current performance position, each score over a plurality of levels is continuously played back to the current score being played including at least the current performance position, the past score that has already been played, and the current score being played. Control the display so that it is displayed as a combination of future musical scores. At this time, at least the current score and the past score, or the current score and the future score are displayed in different display modes. In this way, when displaying the score of the song in a plurality of stages on the display means based on the predetermined song data, each of the “present”, “past”, and “future” score is clearly changed by changing the display mode. The display allows the user to easily check each score that is continuous with “present”, “past”, and “future”.

  The present invention can be constructed and implemented not only as a device 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 present invention, the currently focused score during performance (playing) is “present”, the score that has already been played immediately before that is “past”, and the score that continues to be played after “present” is “future”. ”As the score is displayed on the screen by changing the display mode over a plurality of stages on the display screen, so that the user can easily view the contents of the current, past, and future scores on the screen at a glance. The effect of being able to confirm is obtained.

  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 entire configuration of an electronic musical instrument to which a score display apparatus according to the present invention is applied. The electronic musical instrument shown in this embodiment 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 musical instrument. For this CPU 1, ROM 2, RAM 3, external interface (I / F) 4, input operation unit 5, display unit 6, external storage device 7, and sound source 8 are respectively connected via a communication bus 1D (for example, data and address bus). It is connected. 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 a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined control program, or a memory that temporarily stores a control program currently being executed and related data. used. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like.

  The external interface 4 transmits and receives various information such as control programs and data (for example, “score display processing” (see FIGS. 3A and 3B) described later, automatic performance data, etc.) between the electronic musical instrument and the external device 4A. For example, a MIDI interface or a communication interface. The MIDI interface inputs automatic performance data in so-called MIDI data from an external device 4A (in this case, a MIDI device, etc.) to the electronic musical instrument, or sends MIDI data from the electronic musical instrument to other MIDI devices, etc. This is an interface to output to. Other MIDI devices may be any devices that generate MIDI data in response to user operations, and include any type of controls such as keyboard type, guitar type, wind instrument type, percussion instrument type, and gesture type (or It may be a device). The communication interface is connected to a wired or wireless communication network such as a LAN, the Internet, or a telephone line, and is connected to the external device 4A (in this case, a personal computer, a server computer, etc.) via the communication network. This is an interface for downloading various programs and various data generated by the external device 4A connected via the communication network to the electronic musical instrument main body. Such an external interface 4 may be both wired or wireless and may include both.

  When the external interface 4 is configured with a MIDI interface, the MIDI interface is not limited to a dedicated MIDI interface, but is RS232-C, USB (Universal Serial Bus), IEEE1394 (Itriple 1394), etc. The MIDI interface may be configured using a general-purpose interface. In this case, data other than MIDI event data may be transmitted and received simultaneously. When a general-purpose interface as described above is used as the MIDI interface, other MIDI devices may be able to transmit and receive data other than MIDI event data. Of course, the data format is not limited to data in the MIDI format, and may be in other data formats. In that case, it goes without saying that the MIDI interface and other MIDI devices are configured accordingly.

  The input operation unit 5 is a performance operator such as a keyboard having a plurality of keys for selecting the pitch of a musical tone, or a selection switch for selecting automatic performance data to be displayed as a score. The performance operator such as the keyboard can be used not only for musical performance but also as input means for selecting automatic performance data of a song to be displayed as a musical score. Of course, in addition to these, the input operation unit 5 is a numeric keypad for inputting numeric data, a keyboard for inputting character data, or various devices such as a pointing device (for example, a mouse) used for operating a predetermined pointer displayed on the display 6A. An operator may be included. The display unit 6 is formed on a display 6A composed of, for example, a liquid crystal display panel (LCD), a CRT, or the like, by dividing a musical score of a corresponding song into a plurality of stages (screen division) by a predetermined range based on the selected automatic performance data. In addition to displaying (for each of a plurality of score display areas) (see “score display screen” shown in FIG. 2 to be described later), various information such as a list of automatic performance data capable of displaying a score or the control state of the CPU 1 is displayed. It is for display.

  The external storage device 7 stores various control programs executed by the CPU 1 and various data (“score display processing” described later, automatic performance data, etc.). If no control program is stored in the ROM 2, the control program is stored in the external storage device 7 (for example, a hard disk) and read into the RAM 3 to store the control program in the ROM 2. An operation similar to the case can be executed by the CPU 1. In this way, control programs can be easily added and upgraded. The external storage device 7 is not limited to a hard disk (HD), but can be attached in various forms such as a flexible disk (FD), a compact disk (CD), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). A storage device using an external recording medium may be used. Alternatively, a semiconductor memory or the like may be used.

  The tone generator 8 can simultaneously generate musical tone signals on a plurality of channels, and provides performance information in automatic performance data given via the communication bus 1D, performance information generated in response to operation of the performance operator, and the like. A musical tone signal is generated based on the performance information. A musical sound signal generated from the sound source 8 is generated from a sound system 8A including an amplifier and a speaker. A predetermined effect may be applied to the musical sound signal generated from the sound source 8 using an effect circuit or the like (not shown). The format of the automatic performance data may be digitally encoded such as the MIDI format, or may be a waveform sample data system such as PCM, DPCM, or ADPCM. Any conventional configuration may be used for the configuration of the sound source 8 and the sound system 8A. For example, the sound source 8 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be constituted by dedicated hardware, or by software processing by the CPU 1. Also good.

  In the electronic musical instrument described above, the performance operator is not limited to a keyboard instrument, and may be any type of instrument such as a stringed instrument, a wind instrument, or a percussion instrument. Further, the electronic musical instrument is not limited to the input operation unit 5, the display 6A, the sound source 8, and the like built in one electronic musical instrument body, but each is configured separately, and each of the electronic musical instruments is configured using a communication interface such as a MIDI interface or various networks. Needless to say, the apparatus may be configured to be connected. Furthermore, the musical score display device and the device to which the program is applied according to the present invention are not limited to the form of an electronic musical instrument, but any form of device such as a personal computer, a portable communication terminal such as a mobile phone, a karaoke device, or a game device. -You may apply to equipment. When applied to a portable communication terminal, not only when a predetermined function is completed with only the terminal, but also a part of the function is provided on the server side, and the predetermined function is realized as a whole system composed of the terminal and the server. You may make it do.

  Next, a “score display screen” for displaying the score of the corresponding song based on the song data will be described. FIG. 2 is a conceptual diagram showing an example of a “music score display screen”. However, in order to make the explanation easier to understand, when the fifth measure is being played (playing back) in FIG. 2 (a), the ninth measure is being played (playing back) in FIG. 2 (b). Each case is shown. In this embodiment, the score displayed when “melody score” is designated as the staff type is shown as an example. Here, the “melody score” is a score for the melody part that is composed of only one line of the staff in the high range indicated by the “g clef”.

  The score display screen displays the score of the corresponding song on the display 6A based on song data such as automatic performance data and score display data. As shown in FIG. 2, this score display screen is roughly divided into a plurality of (three in this case) score display areas A1 to A3 and an indicator display area B for displaying a predetermined indicator I. The score display areas A1 to A3 are areas for displaying the score of the corresponding song based on the song data for each predetermined range. In FIG. 2 (a), the score is divided into four bars, and the score including the first four bars from the beginning of the song is displayed as the first-stage score display in the score display area A1, from the fifth bar to the eighth bar. The score including the score from the ninth bar to the twelfth bar is displayed as the second score display in the score display area A3 as the second score display in the score display area A2. In FIG. 2, at the upper left of the score displayed on each level, the number of bars at the beginning of the score displayed on the level is described. Here, the first level “1”, the second level “5”, and the third level “9” are described. The indicator I displayed in the indicator display area B indicates the relative position where the “present” musical score being displayed is located in all the musical scores. The indicator I moves from the upper side to the lower side in the figure in accordance with the performance (reproduction) of the song. That is, the overall length of the indicator display area B is proportional to the length of the song. According to these displays, the user can understand at a glance which musical score the musical score displayed on each stage corresponds to.

  When performance (playback) is started based on the score displayed on each stage, the performance position display C moves from the left to the right on the score in the direction of the arrow X as the performance progresses. Point to. In addition, as the performance progresses, the score displayed on each stage is divided into “present”, “past”, and “future” scores and displayed in a predetermined display mode corresponding to each score. change. For example, the background color of each stage is assigned to be displayed differently. Here, the “present” score is a score in a predetermined musical range (in this case, four bars) including the performance position being played (playing), and the “past” score is a predetermined song corresponding to the immediately preceding score. The score of the range, the score of “future” is the score of the song range that is played (reproduced) following “present”. In FIG. 2A, the “present” score is the second (middle) score displaying the fifth to eighth measures which are currently being played and the performance position display C is displayed. The “past” score is the first (upper) score displaying the first to fourth measures, and the “future” score is from the 9th to the 12th measure. Is the third (lower) score. Of course, in the situation where the “past” score does not exist, that is, before the start of the performance or during the first performance, the first score is replaced with the “present” score, the second and third scores are both “ It goes without saying that the musical score of “future” is displayed in a display mode corresponding to each.

  When the performance progresses from the second score shown in FIG. 2A to the third score shown in FIG. 2B, the current “present”, “past”, and “future” are displayed. The display mode of the corresponding score is changed in accordance with the progress of the song. That is, in this embodiment, when the performance of the entire second score (staff 2) corresponding to the “present” score is completed, the third score (corresponding to the “future” score ( The staff 3) is the "current" score, the second score corresponding to the "present" score (staff 2) is the "past" score, and the first score corresponding to the "past" score. The screen display is updated so that the musical score is a “future” musical score (from the staff 1 to the staff 4) and displayed in a display mode corresponding to each. However, the musical score (staff 4) from the 13th bar to the 16th bar is newly displayed in the first row displaying the “future” musical score. In this way, the display position of the "current" score is displayed as the position of the screen is moved in the order of the upper, middle, lower, upper, and so on as the song progresses. Become. Note that if the “future” score does not exist as the song progresses, that is, while the score including the end of the song is being played, both the first and second scores are “past” scores. The third-stage score is displayed in a display mode corresponding to each so that the score is “present”. Furthermore, it goes without saying that when the performance of the song is finished, the “past” score is displayed in all of the first to third stages.

  As described above, on the score display screen (see FIG. 2), the “present”, “past”, and “future” scores are clearly distinguished and displayed in different display modes. As a result, the user can easily confirm the musical scores corresponding to “present”, “past”, and “future” simply by looking at the score display screen. The display positions of the “present”, “past”, and “future” scores displayed on the score display screen are changed to appropriate positions as the music progresses. Therefore, “score display processing” for displaying each score of “present”, “past”, and “future” in a different display mode in accordance with the progress of the song in a different display mode is used with reference to FIGS. 3A and 3B. I will explain. 3A and 3B are flowcharts showing an example of the “score display processing”. However, here, for convenience of illustration, one continuous “score display process” is divided into two, the process corresponding to the first half of the “score display process” in FIG. 3A, and the first half shown in FIG. 3A in FIG. 3A. The processing corresponding to the latter half of the “score display processing” executed subsequent to the processing is shown separately in each figure. This process is a process executed by the CPU 1 shown in FIG.

  First, automatic performance data is selected as music data to be displayed as a musical score (step S1). Next, various settings are performed (step S2). In step S3, the number of display steps in the screen is determined based on the screen size and staff type input as input. Examples of various settings include staff type, screen size, playback start position, number of bars to be displayed in one score, display color, and the like. For example, as a staff type of a musical score to be displayed, there are “melody score”, “piano score”, “piano narrative score” and the like in addition to the “melody score” shown in this embodiment. "Piano score" is a piano that consists of two lines of stave (specifically, a grand staff), a low-frequency line indicated by "H clef" and a high-frequency line indicated by "G clef". This is a musical score for the performance part. “Piano playing narration” means “melody notation” composed of one line of staves of the high range (melody part) indicated by “treble clef”, low-range line indicated by “sound symbol” and The score is composed of a three-lined staff notation combined with a “piano score” composed of two-lined staff notation (specifically a grand staff) with a high-frequency range line indicated by a “treble clef”. Therefore, for example, in the score display screen shown in FIG. 2, in the case of “piano score”, a score composed of two lines is displayed in each score display area, and in the case of “piano narrative score”, each score is displayed. A score of three lines is displayed in the display area. The display form of the score on the score display screen is determined from the screen size and staff type as described above. The reproduction start position is for designating an appropriate position for starting the performance, and the performance position display C is initially displayed for the corresponding position of the score displayed on the score display screen by this designation. The display color is a color assigned to the background color of each score display area as a display mode for distinguishing each score of “present”, “past”, and “future”. The display mode for distinguishing each score is not limited to a different background color, and the display mode for each score such as highlighting by changing the size of the score or the thickness of the line for each score. As long as they are different, they can be anything.

  In step S4, music data is read to generate score display data. Since any known method may be used for this, description thereof is omitted here. In step S5, it is determined whether or not three stages can be displayed on the score display screen, that is, whether or not the screen area can be divided into three as the score display area. If it is determined that three-stage display is not possible (NO in step S5), the process proceeds to step S21 of the latter half process shown in FIG. 3B described later. For example, depending on the screen size, “melody score” can be displayed in three stages, but “piano playing narration” having a three-line structure may not be displayed in three stages. If it is determined that three-stage display is possible (YES in step S5), it is determined whether or not the set reproduction start position is included in the first song range (step S6). If the reproduction start position is included in the first song range (YES in step S6), the musical score display data of the song range including the reproduction start position is displayed in the “current” display mode on the upper display screen (step S7). . Further, the score display data of the next range of the song range including the reproduction start position is displayed in the middle of the display screen, and the score display data of the next range is further displayed in the “future” display mode on the lower display screen (step). S8). On the other hand, when the playback start position is not included in the first song range (NO in step S6), the score display data of the song range including the playback start position is displayed in the “current” display mode in the middle of the display screen ( Step S9). Further, the score display data of the range immediately before the song range including the reproduction start position is displayed in the “past” display mode in the upper part of the display screen (step S10). Further, the score display data in the range next to the song range including the playback start position is displayed in the “future” display mode in the lower part of the display screen (step S11).

  In step S12, it is determined whether or not there is a reproduction start instruction, and the process is repeated until there is a reproduction start instruction (NO in step S12). If there is a reproduction start instruction (YES in step S12), the following processing in steps S13 to S17 is repeatedly executed until a reproduction end instruction is issued. In step S13, it is determined whether or not a reproduction end instruction has been issued. If there is a reproduction end instruction (YES in step S13), the “score display processing” is ended. In step S14, it is determined whether or not the reproduction position is included in the score of the stage displayed on the display screen in the “current” display mode. If the reproduction position is included in the score of the “current” stage (YES in step S14), the process returns to step S13. When the playback position is not included in the score of the “current” level (NO in step S14), the score of the musical range displayed in the “future” level with respect to the “past” level of the display screen The display data is displayed in the “future” display mode (step S15). However, when there is no next music range, the display may be performed as it is, so that the processing is not performed. In step S16, the display mode of the “current” stage on the display screen is changed to the “past” display mode. In step S17, the display mode of the stage including the playback position on the display screen is changed to the “current” display mode.

  Next, the second half process shown in FIG. 3B executed when it is determined in step S5 that the three-stage display cannot be performed (NO in step S5) will be described. In step S21, it is determined whether or not two-stage display is possible, that is, whether or not the screen area can be divided into two as a score display area. If it is determined that two-stage display is possible (YES in step S21), it is determined whether or not the playback start position is included in the last song range (step S22). If the playback start position is not included in the last song range (NO in step S22), the score display data of the song range including the playback start position is displayed in the “current” display mode on the upper display screen (step S23). ). Further, the musical score display data in the next range of the music range including the reproduction start position is displayed in the “future” display mode in the lower part of the display screen (step S24). On the other hand, when the playback start position is included in the last song range (YES in step S22), the musical score display data of the song range including the playback start position is displayed in the “current” display mode in the lower part of the display screen (step S22). S25). In addition, the score display data in the range immediately before the song range including the reproduction start position is displayed in the “past” display mode in the upper part of the display screen (step S26).

  In step S27, it is determined whether or not there is a reproduction start instruction, and the process is repeated until there is a reproduction start instruction (NO in step S27). If there is a reproduction start instruction (YES in step S27), the following processing from step S28 to step S31 is repeatedly executed until a reproduction end instruction is issued. In step S28, it is determined whether or not a reproduction end instruction has been issued. If there is a reproduction end instruction (YES in step S28), the "score display processing" is ended. In step S29, it is determined whether or not the playback position is included in the stage displayed on the display screen in the “current” display mode. If the playback position is included in the “current” stage (YES in step S29), the process returns to step S28. If the playback position is not included in the “current” level (NO in step S29), the next song range of the song range displayed in the “future” level relative to the “current” level on the display screen is displayed. The musical score display data is displayed in the “future” display mode (step S30). However, if there is no next song range, the display mode is changed from “present” to “past” while the score display data remains unchanged. In step S31, the display mode of the column including the playback position on the display screen is changed to “current”.

  If it is determined in step S21 that two-stage display is not possible (NO in step S21), the musical score display data of the song range including the reproduction start position is displayed on the display screen in the “current” display mode (step S32). ). In step S33, it is determined whether or not there is a reproduction start instruction, and the process is repeated until there is a reproduction start instruction (NO in step S33). If there is a reproduction start instruction (YES in step S33), the following processing from step S34 to step S36 is repeatedly executed until a reproduction end instruction is issued. In step S34, it is determined whether or not there is an instruction to end reproduction. If there is an instruction to end reproduction (YES in step S34), the “score display processing” is ended. In step S35, it is determined whether or not the playback position is included in the stage displayed on the display screen in the “current” display mode. If the reproduction position is included in the “current” stage (YES in step S35), the process returns to step S34. If the playback position is not included in the “current” stage (NO in step S35), the musical score display data of the song range including the playback position is displayed in the “current” display mode on the display screen (step S36).

  As described above, in the above embodiment, when the performance of the “present” score is finished, the “future” score becomes the “present” score, the “present” score becomes the “past” score, and the “past” score. Are updated to the new “future” score. The display position of the “present” musical score is sequentially moved in the order of the upper stage → middle stage → lower stage → upper stage →. Accordingly, the display positions of the “past” score and the “future” score are also moved. In this way, the display mode is changed according to the progress of the song and is clearly displayed on the screen, so that the user can easily display each score of “current”, “past”, and “future” from the screen display. You will be able to confirm. Of course, not limited to this, for example, the display position is fixed as “up” in the upper part of the display screen, “present” in the middle part, and “future” in the lower part, and the displayed score content is updated with playback. It may be structured.

If “present” is a score including the beginning of the song, “past” does not exist, so only two types of “present” and “future” are displayed even if there are three or more score display areas on the display screen. Is done. On the other hand, if “present” is a score including the end of the song, since “future” does not exist, only two types of “present” and “past” are displayed even if there are three or more score display areas on the display screen. Is done.
In the above-described embodiment, the musical score display data created based on the automatic performance data in the MIDI format is used as the musical piece data to be displayed as the musical score. However, the musical score display data is selected directly. Needless to say, this may be used.
Note that the currently focused portion of the displayed score may be, for example, a stage being played back, or may be a portion selected and designated by the user.
In addition, according to the performance operation by the user, each score of “present”, “past”, and “future” may be displayed.

Note that the display form of the score displayed on the score display screen is not limited to the above. The display form of the score may be determined according to the size (size) of the display 6A. For example, the length of a musical score having the maximum vertical width is searched in advance in the entire music, and the number of stages to be displayed at a time is determined from the vertical width of the display screen and the maximum vertical length in the score. The screen may be divided into a plurality of score display areas according to the determined number of stages, and the score corresponding to the corresponding score display area may be displayed sequentially. In addition, when the number of stages that can be displayed at one time is calculated from the size (size) of the display 6A and three stages can be displayed, the display mode of the "present", "past", and "future" stages is changed. The size (size) of the display 6A used at this time may be changeable by a user operation or the like, or may be fixed like an electronic musical instrument with a keyboard. Further, the score display area is not limited to three levels, and may be more than that. In such a case, it is preferable that the display mode is different for each level.
Note that the number of possible display steps may vary depending on the type of staff to be displayed. The staff type may be selectable by the user. In other words, in the above-described “score display screen”, an example is shown in which only one line of the score is arranged in each of the plurality of stages (score display area). Alternatively, a musical score having a different number of lines may be arranged for each stage. In such a case, it goes without saying that all the scores of multiple lines included in each stage are displayed in a display mode assigned to “present”, “past”, and “future”, respectively. For example, if you select a score such as “Piano score” or “Piano narrative score” other than “Melody score” as the staff type of the score you want to display, the score is “Current”, “Past”, and “Future”. Is displayed in multiple lines.
Although an example in which a plurality of score display areas are provided by dividing the screen in the vertical direction is shown as an example, the present invention is not limited thereto, and a plurality of score display areas are provided by dividing the screen in the horizontal direction. You may make it display the score of "present", "past", and "future".
