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

FIG. 1 is a perspective view showing the appearance of a piano 200 including a musical score display device according to an embodiment of the present invention. As shown in the figure, the piano 200 includes a display panel monitor 270 for displaying a score. The display panel monitor 270 includes, for example, a CRT or a liquid crystal panel. The piano 200 has a microphone 260. This microphone 260
Has directivity and is mounted in a direction that makes it easy to pick up the voice of the performer.

FIG. 2 is a diagram showing a mechanical configuration of the piano 200. The piano 200 has 88 keys, and each key is provided with a key sensor 221 as shown in FIG. The key sensor 221 outputs a key state signal corresponding to the pressed / released state of the key 1. The key state signal includes velocity information indicating the strength of key depression when key 1 is depressed.

The piano 200 has an action mechanism 3 for transmitting to the hammer 2 a motion corresponding to the pressing and releasing of the key 1.
It has. When the key 1 is depressed by the player, the action mechanism 3 is operated in conjunction with this, and the hammer 2 rotates upward in the drawing. As a result, the string 4 is hit by the hammer 2 and the string 4 vibrates, thereby generating a musical sound. At this time, the volume of the generated musical tone increases substantially in proportion to the strength at the time of key depression. Specifically, when the player presses the key 1 strongly, the rotation speed of the hammer 2 increases and the hammer 2
As a result, the volume of the generated musical tone increases. On the other hand, when the key 1 depressed by the player is released, the action mechanism 3 is operated in conjunction therewith, and the hammer 2 rotates to the rest position.

FIG. 3 is a block diagram showing an electric configuration of a piano 200 including the musical score display device of the embodiment. In the figure, a CPU (Central Processing Unit) 230
Controls the operation of each unit connected via the bus 250. The RAM 232 is used as a buffer area or a work area for the CPU 230, and temporarily stores various data. The timer 240 generates a clock signal at a constant cycle and supplies the clock signal to the CPU 230.

On the other hand, control program memory 234, score data memory 236, score page change program memory 23
8 is, for example, a magnetic disk or an EEP-ROM (Electrio
nically Erasable and Programmable Read Only Memor
y), and stores information such as various programs and various data indicating the execution procedure of the CPU 230. The information stored in these memories is rewritable. In particular,
When rewriting information, information is written to each memory from an external device connected via an interface (not shown).

Among these memories, the control program memory 234 stores a control program indicating a processing procedure for causing the CPU 230 to control each unit.

The musical score data memory 236 stores musical score data to be displayed on the display panel monitor 270. FIG. 4 is a diagram showing a main configuration of the musical score data. As shown in the figure, the musical score data includes pitch information, rhythm information, page feed information, and page information. The pitch information further includes scale designation information and octave designation information. In the scale information, the scales of the sounds from C (C) to C (B) are designated by using numerals and the width of a semitone is set to 1 based on C (0). For example, "1" shown in the figure indicates that it is a semitone higher than C #.
“2” indicates that the pitch is one tone higher than C (that is, a semitone higher than C #).

The octave designation information indicates the level of the octave with respect to the reference sound by plus / minus signs “+” and “−”.
, And the octave interval for the reference sound is specified by a number. 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 octave is a octave higher than the reference C.

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

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

Next, the score page change program memory 238 shown in FIG.
The program 230 stores a music score page change program indicating a procedure to be executed. More specifically, the score page changing program includes a voice recognition process for causing the CPU 230 to change the displayed score page according to the voice information input from the microphone 260, and a display score page corresponding to the player's key press operation. And an automatic page turning process for changing the displayed score page in accordance with the page turning information included in the score data.

Further, the musical score page change program memory 23
8 stores various data necessary for causing the CPU 230 to execute the voice recognition processing. More specifically, as the data stored in the score page change program memory 238, acoustic model data obtained by modeling the performer's voice in phoneme units, and words related to commands used for page change instructions (for example, next page) And "words" such as "tsugi" and "mae" for displaying the score of the previous page.

The piano 200 is provided with an A / D converter 262. The voice of the player input to the microphone 260 is converted into a digital signal by the A / D converter 262, and then converted to a bus 250. Through the CPU 23
0 is supplied as an audio signal.

Next, the operation of this embodiment will be described.

First, the player operates the display panel monitor 270.
After operating the operation unit (not shown) provided in the power supply of the musical score display device according to the embodiment of the present invention, the music to be played is selected. When a music piece is selected by the player, the CPU 230 reads out the music score data corresponding to the selected music piece from the music score data memory 236. Then, the CPU 230 supplies the score data corresponding to the score of the first page included in the score data to the display panel monitor 270. Thus, the first page of the musical score is displayed on the display panel monitor 270. FIG. 5 shows a display panel monitor 270.
FIG. 7 is a diagram exemplifying the musical score of the first page displayed in FIG. The musical score a shown in the figure is composed of musical notes indicating the pitch and the duration of the sound, and the performer performs the performance of the piano 200 while referring to the musical score a.

In the present embodiment, the player is provided with three means for changing the score page displayed on the display panel monitor 270. The first means is that a player gives a page change instruction by voice. Also,
The second means is that the player gives a page change instruction by a key pressing operation. The third means is to change the page when the player's performance reaches the last bar of the displayed musical score without the player giving a page change instruction.

The piano 200 having the musical score display device according to the present embodiment realizes that the page of the displayed musical score is changed regardless of whether the player uses any of the above three means. It is. Hereinafter, among the operations of the present embodiment, such a page change operation will be described with reference to FIGS.

FIG. 6 is a conceptual diagram of the flow of the page change process performed by the CPU 230. FIGS. 7 and 8 show the CPU.
4 is a flowchart illustrating a procedure of an event interruption process performed by a 230. As shown in FIG. 6, when the player presses a key, or when the player inputs a page change command by voice from the microphone 260, the CPU 230 executes an event interruption process corresponding to each. More specifically, when the player presses a key, the CPU 230
Receives the key state signal from the key sensor 221 provided for the key 1 that has been pressed, and the CPU 230 starts execution of the key pressing event interruption process shown in FIG.

As shown in FIG. 7, the CPU 230 acquires the pitch information by specifying the key sensor 221 that has output the key state signal. Then, velocity information is obtained from the key state signal, and further, time information indicating the time at which the key state signal was received is obtained from a clock circuit built in the CPU 230 (step A1). Next, the CPU 230
Writes the acquired pitch information, velocity information, and time information into the corresponding addresses of the key press event buffer buf1 (see FIG. 6), and increments the address pointer by "1" (step A2).

On the other hand, when the performer inputs a voice from the microphone 260, the CPU 230 sets the A / D converter 2
The voice signal is received from the bus 62 via the bus 250, and the voice input event interrupt processing shown in FIG. 8 is started. As shown in the figure, the CPU 230 acquires an audio signal (step B1), writes this audio signal into a corresponding address of the audio input event buffer buf2, and increments the address pointer by “1” (step B1).
2).

On the other hand, as shown in FIG. 6, in the present embodiment, the CPU 230 executes a timer interrupt process each time a clock signal is output from the timer 240. The timer interrupt process is performed for an unprocessed key press event stored in buf1 and an unprocessed voice input event stored in buf2.

FIG. 9 is a flowchart showing the flow of a timer interrupt process (score page change program) performed by the CPU 230. First, the CPU 230 determines whether or not a new voice input event is stored in the voice input buffer buf2 (step S1). As a result of this determination,
If a new voice input event was not remembered,
The CPU 230 searches for a corresponding address in the key press event buffer buf1, and determines whether an unprocessed key press event is stored (step S2). If the result of this determination is that an unprocessed key press event has not been stored, the timer interrupt process ends. As a result, the processing from step 1 to step 2 is repeatedly executed until a new voice input event or key press event is stored in the buffer.

When the performer starts playing, key press events due to the performance are sequentially written to the key press event buffer buf1. At this time, if the CPU 230 executes the timer interrupt processing, the result of the determination in step S2 becomes positive. Then, the CPU 230 reads an unprocessed key press event from the key press event buffer buf1, and sets the velocity indicated by the key press event to the threshold V.
It is determined whether it is less than th (step S3).
If there are a plurality of unprocessed key press events, the same process is performed for all key press events.

The threshold value Vth of the velocity is set as a value at which the sound volume of the musical sound is weak. That is, in step 3, the performer sets the key 1
It is determined whether or not the key has been pressed at a weak or slow speed so as not to generate a musical tone. Therefore, when the player depresses the key so as to generate a musical tone for playing the music, the determination result in step S3 is negative. Then, the CPU 230 advances the processing procedure to Step S4.

In steps S4 and S5, a performance operation of the player is recorded, and a process of specifying a performance location in the musical score data is performed. More specifically, as shown in FIG. 6, the CPU 230 extracts the pitch information from the key press event read from the key press event buffer buf1, and stores the pitch information in chronological order from the preceding key in the performance recording buffer buf3. (Step S4). Next, the CPU 230 sets the performance recording buffer b
The pitch sequence stored in uf3 is matched with the entire pitch sequence in the musical score data, and a location having the highest degree of matching in the musical score data is identified as a location where the player is performing (step S5). ).

Next, the CPU 230 determines whether or not the part played by the player is the last bar of the displayed musical score in the musical score data (step S6), and when the result of this determination is positive. The CPU 230 stores the score data corresponding to the next page of the displayed score page in the score data memory 23.
6 and output to the display panel monitor 270 (step S7). More specifically, the determination in step S6 is based on whether the CPU 230 refers to the end-of-page information included in the musical score data of the performance location and determines whether or not the flag "T" is present. As a result, when the flag “T” is present, the CPU 230 determines that the performance location is the last bar of the displayed musical score page, and displays the musical score of the next page.

On the other hand, as a result of the determination in step S6,
If the part played by the player is not the last bar of the displayed musical score, the CPU 230 increments the address pointer by the number of key press events read in step S2 (step S8), and ends the interrupt processing.
As a result, when the player is playing the last bar of the displayed musical score, the page of the displayed musical score is automatically turned.

In some cases, a player may want to play a different page from the page currently being played during the performance. In such a case, the player of the piano 200 according to the present embodiment presses the key 1 corresponding to the scale at least one and a half pitches away from the pitch of the playing position with an extremely weak touch to thereby display the page of the score display. Switching can be performed. Hereinafter, an operation in a case where such a key press is performed will be described.

First, when such a key press is performed, the result of the determination in the subsequent step 3 is "YES", and the CPU 230 selects one of the key press events read from the key press event buffer buf1 in step S4. A key press event having a positive determination result is extracted.
Next, the CPU 230 determines whether or not the pitch difference between the pitch indicated by the extracted key press event and the pitch specified by the player in the musical score data is one and a half or more. (Step S9). At the time of this determination, the result of the performance location identification processing in step S5 is referred to as the performance location of the player in the musical score data.

In step S9, the CPU 23
A value of 0 determines whether the key press event whose velocity is equal to or lower than the threshold value Vth is caused by the player to instruct a change in the displayed musical score page or is caused by a mistouch. Specifically, the player presses a key 1 having a pitch different from the pitch designated by the score data (for example, a key 1 adjacent to the key 1 designated by the score data) by a mistouch. There are cases. Therefore, in step S9, the CPU 230 determines whether or not the pitch interval between the pitch of the key 1 pressed by the player and the pitch specified by the score data is within one and a half pitch. I have. As a result of this determination, if the pitch interval is within one and a half notes, the CPU 2
30 determines that the key is pressed due to a mistouch, and advances the processing procedure to step S4. Therefore, from the discrimination between step S3 and step S9, it can be accurately determined whether or not the player has instructed a page change by a key pressing operation during the performance.

Next, if there is a key press event for which the determination result in step S9 is affirmative, the CPU 230 extracts the key press event, and then the CCPU 230 generates time information of the extracted key press event. Then, it is determined whether or not the recording time of the last recorded key press event is earlier than the current time by a set time or more (step S10). This set time is preferably set to be equal to or longer than the time required for the player to repeatedly hit the same key 1. As a result, even when the player gives a page change instruction by repeatedly hitting the same key, the instruction given by the player is
230 to get exactly.

If the result of the determination in step S10 is negative, the CPU 230 ends the interrupt processing. On the other hand, if the result of the determination in step S10 is positive, the CPU 230 determines whether or not the keypress event is due to the same key continuous tapping performed by the player, Determine whether it is. Further, in the case of the same key continuous hit, it is determined how many times the player has performed the continuous hit, and in the case of the simultaneous hit, how many keys are simultaneously hit is determined (step S11).

If the result of determination in step S11 is that the player has issued a page change instruction with a single hit,
The PU 230 reads out the score data corresponding to the score of the next page from the score data memory 236 and
70 (step S12). Thus, the score of the next page is displayed on the display panel monitor 270. If it is determined that the player has performed the page change instruction twice with the same key or with two keys at the same time, the CPU 230
The musical score data corresponding to the musical score of the previous page is read out from the musical score data memory 236 and output to the display panel monitor 270 (step S13). Thereby, the display panel monitor 2
70 displays the musical score of the previous page. If it is determined that the player has performed the page change instruction with the same key three times or with the same key, the CPU 230 reads out the score data corresponding to the first page of the score from the score data memory 236. The output is output to the display panel monitor 270 (step S14). As a result, the first page of the score is displayed on the display panel monitor 270.

Next, the CPU 230 increments the address pointer by the number of key press events read in step S2 (step S15), and ends the interrupt processing.

On the other hand, if the result of determination in step S11 does not correspond to any of the above cases, the CPU
In step 230, the process proceeds to step S4.

As a result of the determination in step S1,
If it is determined that there is a voice input event, the CPU 230
Reads the audio input event (audio signal) from the audio input event buffer buf2, executes a page change process corresponding to the audio signal (step S16), and ends the timer interrupt process.

More specifically, CPU 230 divides the audio signal read from the corresponding address in audio input event buffer buf2 into phoneme signals in predetermined frame units. Next, the CPU 230 compares each phoneme signal with acoustic model data stored in the musical score page change program memory 238, and executes a phoneme analysis process for specifying a phoneme specified by each phoneme signal. And
The CPU 230 stores the phoneme sequence provisionally specified by such a voice analysis process and the score page change program memory 2.
A comparison is made with each word stored in 38 to determine the word that best matches both, and a command specified by this word is obtained. And the CPU 230
After the displayed musical score page is changed in response to the acquired command, the address pointer is incremented by "1", and the timer interrupt processing ends.

FIG. 10 is a conceptual diagram showing a page changing operation performed by such a procedure. Score G shown in the figure
Indicates conceptually the musical score data stored in the musical score data memory 234 as a musical score. In the musical score G, page boundaries are indicated by dashed lines.

For example, it is assumed that the display panel monitor 270 is displaying the score of the third page corresponding to the score data p3. At this time, the performer gives an instruction to display the next page by voice, or presses the key 1 whose pitch is separated by more than one and a half pitch from the pitch specified by the playing position in the score data, and whose velocity is equal to or less than the threshold value. Press the key only once so that In this case, the CPU 230 determines that the player has instructed page turning, reads the score data p4 corresponding to the fourth page from the score data memory 236, and displays the score of the fourth page on the display panel monitor 270. Further, even when the player performs the last bar of the displayed score page without giving a special instruction, the next page of the score is displayed on the display panel monitor 270.

On the other hand, if the performer gives an instruction to display the previous page by voice or hits the same key twice or two keys at the same time by the same key pressing operation, the CPU 230 determines whether the player It is determined that page return has been instructed, and the score data p2 of the second page, which has been returned by one page from the third page, is stored in the score data memory 234.
, And the musical score of the second page is displayed on the display panel monitor 270. If the performer gives an instruction to display the first page by voice or performs the same key three times or the same key three times by the same key pressing operation, the CPU 230
Determines that the player has instructed to return to the first page,
The musical score data p1 corresponding to the first page is read from the musical score data memory 234, and the musical score of the first page is displayed on the display panel monitor 270.

As described above, in the piano 200 provided with the musical score display device of the present embodiment, the player can easily change the page of the musical score to be displayed without releasing his hand from the keyboard during the performance. Can be. Also, only the score need be displayed on the display panel monitor, and as is conventionally done,
There is no need to display control buttons for manual operation. Therefore, even if a display panel monitor having the same display area as the conventional one is used, the space for displaying the score can be widened.

<Modification of Embodiment> The embodiment described above
This shows one embodiment of the present invention, and can be arbitrarily changed within the technical idea of the present invention. Therefore, a modified example will be described below.

(A) For example, in the above-described embodiment, when both the determination results in step S3 and step S9 are affirmative, the musical score displayed on the display panel monitor 270 in accordance with the recorded key press event. Although the page is changed, the score page to be displayed may be changed when either one of the determination results in step S3 and step S9 is positive.

(B) Also, for example, the page of the musical score to be displayed is
The performer may directly specify it. In particular,
Specify the tens place of the number of pages by pressing the black key so that the velocity is below the threshold, and specify the number of pages by pressing the white key so that the velocity is below the threshold. Make sure to specify the first place.

(C) Further, for example, in the above-described embodiment, the musical score data includes page information in advance, but the present invention is not limited to this. At the end of the staff specified by the flag. In this configuration, each time the player plays the last note of each staff, the displayed score scrolls by one staff. More specifically, as shown in FIG. 11, three staff stages d2, d3, and d4 are designated as display sections D in the musical score data. In this case, when the player performs in accordance with the displayed musical score and plays, for example, the last note of the staff d2, the CPU 230 newly designates a display section including the staff d3, d4, and d5. The musical score of the designated display section is displayed on the display panel monitor 270.

Further, in this configuration, for example, for a specific key out of 88 keys, the velocity at the time of depressing the key is detected, and when the detected velocity is equal to or less than the threshold, the key is depressed. The score displayed on the display panel monitor 270 may be scrolled by the staff corresponding to the key count. In addition, the scrolling direction may be changed according to the number of keys pressed simultaneously so that the velocity is equal to or less than the threshold value.

More specifically, as shown in FIG. 11, the display section including the staff stages d2, d3 and d4 is determined by the CPU.
When the player has pressed only one key so that the velocity is equal to or less than the threshold value when the key 230 is designated, the CPU 230 acquires the key pressing event,
In the musical score data, the display area is set to staff levels d3, d4, d5.
Change to include Then, the CPU 230 outputs the score data corresponding to the changed display section to the display panel monitor 270, and scrolls the displayed score by one staff line in the forward direction (moving direction of music). On the other hand, when the player strikes two keys at the same time so that the velocity becomes equal to or less than the threshold value, the CPU 230 obtains the key press event and then sets the display section in the score data to the staff d1, d
2. Update to include d3. And the CPU 230
Outputs the musical score data corresponding to the changed display area to the display panel monitor 270, and scrolls the displayed musical score by one staff line in the reverse direction (the direction opposite to the music progression direction).

Furthermore, for example, when a player performs three keys simultaneously so that the velocity becomes equal to or less than the threshold value, the vicinity of the performance position of the player in the musical score may be enlarged and displayed. More specifically, when the player is playing near the note n in the musical score shown in FIG. 12A, the player performs three-key simultaneous tapping so that the velocity becomes equal to or less than the threshold value. Do. After acquiring the key press event, the CPU 230 designates a display section R of several notes from the place where the player is performing in the score data, and displays the score data corresponding to this display section on the display panel monitor 270. To display the score in an enlarged scale. When the musical score is enlarged and displayed, a window R ′ for enlarged display may be opened above the normal musical score as shown in FIG.

(D) The microphone 260 is not fixed to the piano 200, but may be a pin-type microphone that is attached to the player's neck or the like. By arranging the microphone near the neck of the player, it is easy to pick up the voice uttered by the player, and the effect of the piano performance sound on the voice uttered by the player is suppressed.

(E) Further, in this embodiment, an example in which the present invention is applied to a piano has been described. However, the present invention may be applied to, for example, an electronic musical instrument or a natural musical instrument which does not have such an automatic performance mechanism. . Further, the present invention can change the page of the displayed musical score without releasing the player from the performance operator of the musical instrument, and is not limited to a keyboard instrument such as a piano.
The present invention is applicable to musical instruments that generate musical tones according to the operation state of a performance operator of a player. As an instrument of this kind, for example,
There are wind instruments such as clarinet and flute, and string instruments such as guitar and violin.

(F) In this embodiment, the musical instrument provided with the musical score display device has been described. However, the musical score display device does not need to be provided in the musical instrument, and as shown in FIG. May be separated from the musical instrument. In the configuration shown in FIG.
Includes a display panel monitor 502. The display panel monitor 502 is, for example, a CRT or a liquid crystal panel. The score display device 500 includes a switch unit 506. The switch unit 506 is used when the player turns on the main power of the musical score display device 500 or selects a music piece. Further, the musical score display device 504
