The MIDI data stored in the data memory 24 is MIDI data for playing a piece of music (for example, a symphony) composed of a plurality of parts, and is composed of track data for playing each part of the piece of music. ing. Each track data is composed of sequence data including event data, timing data indicating these time intervals, and end data. The event data has data indicating a note-on event, a note-off event, a note number, and velocity. Each track data is, for example, a piano part,
It is data for playing a musical instrument such as a violin part. By simultaneously playing back and playing the track data of each of these parts, it is possible to play back a musical piece composed of a plurality of parts. Further, not only can all of these track data be played and reproduced at the same time, but each track data can be used alone or in an appropriate combination to play and play only a specific part.

The musical score data area of the data memory 24 stores musical score data for displaying the musical score on the display screens 2 and 3 for each part constituting the music stored in the MIDI data storing area of the data memory 24.

Here, the musical score data for displaying the musical score of each part is associated with the track number of the MIDI data of the corresponding music, so that among the MIDI data of one music with which musical score data exists. It is possible to identify which of the track data corresponds to the track data.

Here, FIG. 6 shows an example of musical score data of one part. As shown in the figure, the musical score data includes pitch information, rhythm information, page end information, and page information. The pitch information further includes scale information and octave information.

For the scale information, the scales are specified by using the numbers from C to C to the numbers with a half-tone width of 1 based on the "0". For example, "1" shown in the figure is
Do # is a semitone higher than Do, and “2” indicates that it is one tone higher than Do (that is, a semitone higher than Do #).

In the octave designation information, the pitch of the octave with respect to the reference tone is represented by positive and negative signs "+" and "-".
And the octave interval for the reference tone is specified by numbers. For example, "+1" specifies a sound one octave higher than the reference sound, and "-1" specifies a sound one octave lower than the reference sound. Therefore, when the scale information is “1” and the octave information is “+1”, it means that the de # is one octave higher than the reference de.

On the other hand, in the rhythm information, a quarter note is used as a reference for the length of a note, and this quarter note is represented by "1". For example, "0.5" shown in the same figure is an eighth note that is a half of a quarter note, and "4" specifies a whole note corresponding to four quarter notes.

Further, the page end information specifies the sound included in the last bar of each page in the score data by the flag "T". The page information is used to specify to which page of the score the pitch information and the rhythm information belong. In addition to the above-mentioned information, the musical score data includes, for example, tempo information designating the tempo at the time of performance, information indicating the title of the song, composer name, lyricist name, and the like.

The musical score display device 1 includes a CPU 2
0 reads out the score data of the corresponding music (song) page by page based on the instruction of the performer and generates the image data of the score of the staff by a predetermined algorithm, thereby displaying each page of the score on the display screens 2, 3 Can be displayed on each.

B. Operation of the Embodiment Next, the processing operation executed in the musical score display device 1 having the above configuration will be described. The musical score display device 1 has a plurality of operation modes, and a user operates the operation switch group 4

Further, it is possible to generate a musical sound according to the MIDI data stored in the data memory 24. Specifically, the musical score display device 1 of the present embodiment allows the user to select four operation modes such as a musical score display mode, a shooting mode, a recording mode, and a minus one performance display mode. The processing operation of the score displaying apparatus 1 when each of these operation modes is selected will be described.

B-1. Musical score display mode The musical score display mode is a mode in which a musical score is displayed on the display screens 2 and 3, and when this operation mode is selected by the user, the CPU 20 causes the musical score and the musical score of the part designated by the performer from the data memory 24. The data is read, and first, the first page of the score is displayed on the display screen 2, and the second page of the score is displayed on the display screen 3.

As shown in FIG. 7, in the score display mode, C
The PU 20 not only displays the score on the display screens 2 and 3, but also an operation for instructing a process of changing the display content such as page turning, page returning, returning to the beginning of the page, and displaying another score. Button group (software button group) 3
It is controlled so that 0 is displayed on the display screen 2. And
When any operation button is pressed by the user's operation, the touched position is detected by the touch panel 11A, and the CPU 20 determines which operation button is pressed from the detection result. The CPU 20 executes the processing operation according to the operation button specified by this determination. More specifically, the CPU 20 performs a process of changing the score page displayed on the display screens 2 and 3. For example, when it is detected that the page feed button is pressed, the CPU 20 updates the score page displayed on the display screen 2 to the page two pages after, and at the same time, displays the score page displayed on the display screen 3. Is updated to the page two pages after. In other words, the odd number page of the score is displayed on the display screen 2, the even number page of the score is displayed on the display screen 3, and consecutive pages are simultaneously displayed.

As a result, in this score display mode, not only can successive pages of the score be displayed at the same time as in the case of a paper score, but the pages of the score that are displayed in the same way as when the pages are actually turned are updated. can do. Therefore,
It is possible to prevent a player who is practicing performance while referring to a conventional paper score from feeling uncomfortable. Further, in the musical score display device 1, the player can perform page turning and the like by only pressing the operation button group 30 displayed on the display screen 2 once, so that page turning like a paper-based score is possible. It is possible to avoid the case of making a mistake or turning the page due to the wind, and it is possible to perform an operation such as page turning more easily and more reliably than a paper-based score.

In FIG. 7, the operation button group 40
Is a software button group that is always displayed regardless of the operation mode. Specifically, the operation mode of the musical score display device 1 is any one of the musical score display mode, the shooting mode, the recording mode, and the minus one performance display mode. Includes multiple operating buttons to switch to mode. Therefore, when the operation button for changing the operation mode of the operation button group 40 is pressed, the CPU 20 switches the operation mode.

B-2. Shooting Mode The shooting mode is a mode for shooting the performer, and when this operation mode is selected, the CPU 20 displays the shot image 50 of the camera 7 on the display screen 3. As shown in the display example of the shooting mode in FIG. 8, the shot image 5 is displayed on the display screen 3.
In addition to 0, an operation button group 60 for instructing processing such as recording start, recording stop, and reproduction is displayed. Further, the CPU 20 causes the other display screen 2 to display either the score displayed before the switching to the shooting mode or the score corresponding to the score data designated by the performer.

When any one of the operation button groups 60 is pressed, the CPU 20 causes the camera 7 to operate.
Recording processing for recording moving image data corresponding to the captured image 50 input via the microphone and audio data input via the microphone 8 in the user data memory 25 in synchronization with each other, or recording stop processing, or user data. Reproduction processing of moving image data and audio data recorded in advance in the memory 25 is performed. In addition, in this recording process, the moving image data is transferred to MPEG (Moving Picture).
The video data may be recorded by performing a compression coding process using a video coding algorithm such as Experts Group 2). Similarly, the compression coding process is performed on the audio data using a voice coding algorithm such as MPEG1 (layer 3). You may make it record it. Further, only moving image data may be recorded.

Also in this mode, the operation button group 30 is displayed to accept the page operation of the musical score, but when the page forward button or the page return button is pressed, the CPU
20 is different from the above score display mode in the display screen 2
The process of changing the musical score page displayed in 1 page unit is performed. The captured image 50 may be displayed on the display screen 2 and the score may be displayed on the display screen 3, or it may be selectable on which display screen the captured image 50 is displayed.

As a result, in this photographing mode,
Since the score and the photographed image 50 can be displayed at the positions adjacent to each other, the performer plays the musical instrument while looking at the score displayed on the one display screen 2, and at the same time, displays it on the other display screen 3. It is possible to easily perform the shooting operation while monitoring the performed performance of the player.

B-3. Recording Mode The recording mode is a mode for recording and reproducing a performance sound and a singing voice, and when this operation mode is selected, the CPU 20
Causes the display screen 3 to display a group of operation buttons (not shown) for instructing processing such as recording start, recording stop, and reproduction of the voice input from the microphone 8. The CPU 20 is adapted to record the voice data input via the microphone 8 in the user data memory 25 in response to the pressing operation of these operation buttons, or reproduce the voice data recorded in the user data memory 25. There is.

Also in this recording mode, the CPU
Similarly to the shooting mode 20, the display screen 2 displays the score displayed before switching to the recording mode or the score corresponding to the score data specified by the performer.
As a result, the performer can play the musical instrument while looking at the score displayed on the display screen 2 on one side, and at the same time operate the operation buttons displayed on the display screen 3 on the other side to produce his or her performance sound or singing voice. You can record easily.

B-4. Minus one performance mode The minus one performance mode is an operation mode for assisting performance practice of one part having a musical piece composed of a plurality of parts such as a symphony. When the minus one performance mode is selected, the CPU 20 executes the processing according to the flowchart shown in FIG.

As shown in the figure, when the minus one performance mode is selected, the CPU 20 displays a screen for allowing the user to specify which part of which music is to be practiced for performance on both the display screens 2 and 3. It is displayed on either one (step Sa1). For example, M in the data memory 24
By displaying the names of all the songs in which the IDI data and the score data are stored and the part names of each song, and detecting which part name of which song name is touched by the user, Should be specified.

When a screen for prompting the designation of music and parts is displayed on the display screens 2 and 3 as described above, the CPU 20
Determines whether the music and the part are designated by the user (step Sa2). User display screen 2, 3
When it is detected that the music and the part are designated by the touch operation or the like, the CPU 20 stores the score data for displaying the score of the part of the designated music in the data memory 2.
4, and the score of the designated music and part is displayed on the display screens 2 and 3 (step Sa3). Here, similar to the score display mode described above, software for displaying the first page of the score of the designated music and part on the display screen 2 and the second page on the display screen 3 and for prompting the start of performance. The button is displayed on either of the display screens 2 and 3. When such a performance start instruction is displayed, the state of waiting for the performance start instruction is entered, and the CPU 20 determines whether or not the performance start instruction is given (step Sa).
4).

When the soft button for instructing the performance start displayed on any of the display screens 2 and 3 as described above is pressed, the CPU 20 causes the M included in the designated music.
In the IDI data, the process for playing the music is started based on the data of the track corresponding to a part other than the designated part, and the score display process is executed according to the progress of the music playing based on the MIDI data (step S
a5). Therefore, for example, when the user designates a piano part of a certain music to perform a minus one performance, the CPU 20 causes the track data other than the piano part of the MIDI data of the music (for example, violin or cello). (The track data corresponding to the part of) is read from the data memory 24 to the RAM 22 or the like,
The event data is supplied to the sound source 28 at a timing according to the timing data described in each of these track data. Thus, the tone generator 28 generates a tone signal according to the description of each track data, and the speaker 9 emits the tone signal. In this way, the part of the designated music other than the piano is played.

The CPU 20 executes processing for playing a part other than the designated part as described above, and
The score display is controlled according to the progress of the music performance. More specifically, when the music performance is started as described above, the CPU 20 counts the time from the start of the performance, and the score currently displayed on the display screens 2 and 3 each time a predetermined time elapses. Is changed to the score display on the next page. Here, the predetermined time is a value determined according to the performance tempo of the designated music and the number of bars in the score displayed on one page. In the present embodiment, since two pages of music can be displayed on the display screens 2 and 3, the number of measures displayed on two pages is multiplied by the absolute time for one bar calculated from the performance tempo. The value is the time required for the performance shown in the score for two pages. The CPU 20 obtains the time required to play the score displayed on two pages in this way, and when this time has elapsed since the performance started, the CPU 20 executes the process of advancing the score display to the next page and counts the time. Reset the value and start counting again. Then, when the time required for the above two pages elapses from the re-count, a process of further advancing the score display to the next page is performed, and thereafter, the same process is repeatedly executed. The operation of page turning of the score display here is the same as that of the score display mode, and the display screens 2 and 3 are switched at the timing.

In this way, the musical score of the part designated by the user is displayed on the display screens 2 and 3, and the performance sound of the part other than the part designated by the user is emitted from the speaker 9. Then, the CPU 20 determines whether or not the music has ended (step Sa6), and when the music has ended (M
When the end data of the IDI data is detected), the processing operation in the minus one performance mode is ended.

As described above, in the minus one performance mode, the musical composition other than the part designated by the user is played, and the musical score display of the part designated by the user is appropriately controlled according to the progress of the performance. Therefore, the user can practice the performance of the part designated by himself / herself while visually referring to the score of the part designated by himself / herself, and also by aurally referring to the performance sound of another part. For example, when practicing the piano part of a certain piece of music, the user can refer to the musical score for playing the piano part of the certain piece of music on the display screens 2 and 3, while the speaker 9 plays the musical score of the certain piece of music. Performance sounds of other parts, such as a violin and cello, are emitted, and the piano part can be practiced while matching the performance sounds of these other parts. Therefore, even when the user performs the performance practice of a part having a music composed of a plurality of parts by himself, the user can perform the effective performance practice in consideration of the cooperation between the parts of the music.

Further, since the musical score display device 1 according to the present embodiment is of the foldable type which is easy to carry as described above, when the musical performance practice of a certain music piece is performed jointly by the players of each part. In the above-mentioned score display mode, the score display device 1 is used to practice the performance, and when returning to home or the like to practice the performance alone, the score display device 1 is used in the minus one performance mode. It becomes possible to say such.

C. Modifications The present invention is not limited to the above-described embodiment, and various modifications as exemplified below are possible.

(Modification 1) In the above-described embodiment, the user can select four operation modes such as the score display mode, the shooting mode, the recording mode and the minus one performance display mode. In addition to the above operation mode, a performance content display mode as described below may be selectable.

The performance content display mode, like the minus one performance mode described above, assists the performance practice of one part having a musical piece composed of a plurality of parts such as a symphony, and the content of the performance practice in real time. This is an operation mode in which the player is informed by. When using the musical score display device 1 in this performance content display mode, it is necessary to connect the musical score display device 1 to an electronic musical instrument or the like that can generate data according to the performance content of the performer. For example, in FIG.
The MIDI supplied from the electronic piano 150 by connecting the electronic piano 150 to the musical score display device 1 as shown in FIG.
The performance contents are displayed on the display screens 2 and 3 of the musical score display device 1 using the data.

Here, prior to the description of the processing operation of the musical score display apparatus 1 when the performance content display mode is selected, the electronic piano 150 connected to the musical score display apparatus 1 in the operation mode will be described with reference to FIG. explain.

The piano 150 includes an action mechanism 103 for transmitting the movement of the key 101 to the hammer 102, a string 104 hit by the hammer 102, a solenoid 105 for driving the key 101, and a damper for stopping the vibration of the string 104. 106 is provided, and these configurations are similar to those of a general automatic piano. Besides, this piano 15
0 has the same mechanism as that mounted on a normal acoustic piano.

Further, the piano 150 includes a controller 111, a servo controller 112, and an electronic musical tone generating section 1.
25, a key sensor 126 and a MIDI interface 110.

The controller 111 has a CPU, a ROM and a RAM, and controls each part of the piano 150 according to a control program stored in the ROM.

The servo controller 112 supplies an exciting current according to the speed instruction value to the solenoid 105, compares the output speed as a feedback signal supplied from the solenoid 105 with the speed instruction value, and confirms that they match. Servo control is performed, and the speed instruction value is appropriately output from the controller 111 as a value indicating the speed corresponding to the position of the key 101 at each time.

The electronic tone generator 125 is the controller 1
The electronic tone is generated under the control of 11, and is composed of a sound source, a speaker, and the like.

The key sensor 126 is provided on the lower surface side of each key 101 and detects the operation of the corresponding key 101. The key sensor 126 detects a signal indicating the state of each key 101 and outputs it to the controller 111. The controller 111 supplies a control signal to the electronic musical sound generator 125 based on the signals supplied from these key sensors 126. As a result, it is possible to electronically generate a musical sound corresponding to the operation of the key 101.

Further, the controller 111 generates MIDI data in real time based on the detection result of the key sensor 126, and in the performance content display mode, the generated MIDI data, that is, the MIDI data according to the performance content of the user. Sequential MIDI interface 110
Is transmitted to the musical score display device 1 via. For example, when the player presses the key 101 corresponding to the sound of "do" and the press is detected by the key sensor 126, the note-on event data of the note number corresponding to the "do" is generated. The MIDI interface 110 can transmit and receive MIDI data to and from an external electronic musical instrument, and the MID corresponding to the performance content generated by the controller 111 as described above.
Not only the I data can be transmitted, but MIDI data supplied from another device such as the musical score display device 1 can be received and taken into the electronic piano 150.

The above is the configuration of the electronic piano 150. The player places the musical score display device 1 on the music stand of the electronic piano 150, for example, and makes it possible to exchange signals (MIDI data) between them. By connecting and referring to the score displayed on the display screens 2 and 3 of the score display device 1 set to the performance content display mode, the key 101 of the electronic piano 150 is operated to practice the performance.

When the performance content display mode is selected, the CPU 20 of the musical score display device 1 executes the processing according to the flowchart shown in FIG. 9 as in the above-described minus one performance mode, and receives a performance start instruction. (Determination “YES” in step Sa4), the MIDI data corresponding to the user's performance content supplied from the electronic piano 150 is used to display information indicating the content of the user's performance on the display screens 2, 3
The score of the part specified by the user (step S in FIG. 9).
(See a5) is displayed in parallel with the processing in the minus one performance mode.

As shown in FIG. 11, when there is a performance start instruction from the user, the CPU 20 causes the M stored in the data memory 24 to be the same as in the minus one performance mode described above.
A performance based on the IDI data is started, and time measurement is started from the performance start point (step Sb1).
This time measurement is used to detect a note-on event data input time, a note-off event data input time, and the like, which will be described later.

Next, the CPU 20 determines whether or not MIDI data is input from the electronic piano 150 via the MIDI interface 27 (step Sb2). That is, it is determined whether or not the MIDI data according to the performance content of the player on the electronic piano 150 has been supplied to the musical score display device 1.

When MIDI data is input (determination “YES” in step Sb2), the CPU 20
Determines whether the input MIDI data is a note-on event (step Sb3). Input M
When the IDI data is the note-on event data, the note-on event data is stored in the RAM 22 in association with the time information indicating the elapsed time from the performance start when the note-on event data is input. (Step Sb4). For example, the note-on event data input 35 seconds after the performance starts is stored in the RAM 22 in association with the time information representing 35 seconds.

Then, it is judged whether or not the music performance based on the MIDI data stored in the data memory 24, which is executed similarly to the minus one performance mode, is completed (step Sb5). Here, if the performance is not finished,
Returning to step Sb2, the CPU 20 determines whether or not MIDI data has been input, and if the performance has ended, the processing in the performance content display mode ends.

On the other hand, if it is determined in step Sb3 that the input MIDI data is not note-on event data, that is, note-off event data (determination "NO" in step Sb3), RAM2
From the note-on event data stored in No. 2, the CPU 20 identifies the note-on event data corresponding to the note-off event data (step S
b6). When the note-on event data is input as described above, the note-on event data is stored in the RAM 22 together with the time information. Step Sb
In 6, the CPU 20 identifies the note-on event data corresponding to the input note-off event data from the note-on event data stored together with the time information in this way. Here, note-on event data corresponding to note-off event data is
The note-on event data is the note-on event data having the same note number, that is, the note-on event data indicating the sounding of the same pitch.

When the CPU 20 specifies the note-on event data corresponding to the input note-off event data, the CPU 20 passes the time (T2) from the start of the performance when the note-off event data is input.
And the note-on duration TK is calculated based on the time information (T1) stored in association with the specified note-on event data (step Sb).
7). More specifically, the calculation of TK = T2-T1 is performed to calculate the note-on duration TK.

When the note-on duration TK is calculated in this manner, the CPU 20 applies the MIDI data generated by the electronic piano 150 by the performance of the performer, that is, the performance content to the display of the display screens 2 and 3 in order. The position at which the note-on event is to be displayed is specified (step Sb8). More specifically, the CPU 20
Specifies the display position from the time T1 associated with the specified note-on event data. As described above, in the minus one playing mode, when the user specifies a part of a certain music, the score of the specified part is displayed on the display screens 2 and 3 as shown in FIG. 7, for example. ing. Here, the number of staffs of the musical score displayed on the display screens 2 and 3, the number of measures included in one staff notation, etc. are predetermined for each music, and the performance tempo is determined for each music. Therefore, the position on the score of a certain part of a piece of music displayed on the display screens 2 and 3 corresponds to the elapsed time from the start of the performance. For example, the position at which a note or the like to be played is displayed 35 seconds after the start of performance can be uniquely specified by the music and the part. When the music and the part are designated in this way, the position on the screen of the display screens 2 and 3 on which the score is displayed is changed according to the elapsed time from the start of the performance of the part based on the performance tempo and the content of the score of the music. Can be specified. Therefore, when the performance content display mode is selected, the CPU
The reference numeral 20 creates a table in which the elapsed time and the display position are associated with each other for the designated music part and stores the table in the RAM 22. Then, the CPU 20 refers to this table and identifies the display position from the elapsed time T1 corresponding to the note-on event data identified as described above.

When the display position is specified as described above, CP
U20 displays the specified display position at the above-mentioned step Sb3.
Control is performed to display the note-on and note-off event data that was the processing target in step Sb7 on the display screens 2 and 3 (step Sb9). That is,
The player performs control to display the contents of the performance operation performed on the electronic piano 150 on the display screens 2 and 3. In the present modification, as shown in FIG. 12, the pitch is specified from the note number shown in the target note-on and note-off event data in order to reflect such performance content, and from the duration TK. The type of note (half note, quarter note, etc.) is specified, and the note R reflecting the specification result is displayed at the display position specified as described above. In the example shown in the figure, from the duration TK to 4
This is the display content when it is specified that it is a quarter note, and that it is specified as the sound of "Mi" from the note number. In FIG. 12, a note M is a note included in the score of the part of the music designated by the user as in the minus one performance mode described above. In this modified example, the musical note R reflecting the performance content is displayed at a position slightly different from the musical note M based on the musical score data, so that the musical note R, which is the content of the musical performance operation of itself, and the musical note M serving as a model based on the musical score data. It is possible to refer to by contrasting with. At this time, the musical note M based on the musical score data is displayed in a normal black color or the like, and the musical note R corresponding to the performance operation content of the performer is displayed in another display color such as red, whereby the performer performs his or her own operation. It is easier to compare the content with the model.

In the score display based on the score data as described above, a MIDI generated according to the performance content of the performer is displayed.
When the control of displaying the notes based on the data is over, the CPU 20 determines whether or not the music performance based on the MIDI data stored in the data memory 24, which is executed similarly to the minus one performance mode, is completed (step S
b5). If the performance has not ended, the process returns to step Sb2, and the CPU 20 determines whether or not MIDI data has been input. If the performance has ended, the processing in the performance content display mode is executed. finish.

The CPU 20 displays the note-on event data and the note-on event data by superimposing the above-described score display based on the score data and displaying a note corresponding to the performance operation content performed by the performer on the electronic piano 150. Each time note-off event data corresponding to is input, it is executed in real time, so that the musical notes or the like corresponding to the performance content are successively overlapped and displayed on the score displayed on the display screens 2 and 3 based on the score data. To be done. Therefore, the player can easily compare the model with the content of his / her own performance while playing, by referring to the score displayed on the score display device 1, and it is possible to assist effective performance practice. .

(Modification 2) In the performance content display mode described in the above modification, the performance operation content performed by the player on the electronic piano 150 is displayed on the display screens 2 and 3 in real time.
