The pitch and length of the input note are recognized, and the note corresponding to the recognized pitch and length is displayed on the staff.

[0003]

However, in such a conventional device, since the handwritten input notes are simply recognized and displayed, the handwritten input notes are recognized and displayed. Then, it is impossible to reorganize the score composed of the displayed notes, such as changing the displayed notes.

The present invention has been made in view of such conventional problems, and provides a music information input method and a music information input device capable of modifying a previously displayed musical score by pen operation. The purpose is.

[0005]

In order to solve the above-mentioned problems, in a music information input method according to the present invention, an input musical score is displayed, and a handwriting operator is added to a note on the displayed musical score. An operation is detected, and the note is displayed and changed according to the detected mode of the additional operation. Further, in the note editing device according to the present invention, display means, score display means for displaying the score input to the display means, and handwriting operator for the notes on the score displayed on the display means And a note change processing means for changing the display of the note according to the mode of the additional operation detected by the detecting means. In addition, preferably, when the number of beats of the bar to which the note belongs does not match with the time signature due to the display change of the note, the bar is displayed in a display state different from other bars.

[0006]

In the above music information input method, when the handwriting operator is operated on the displayed musical score to perform an additional operation of adding a flag or a stick to the displayed notes, the mode of the additional operation is detected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. That is, FIG. 1 is a block diagram showing the overall configuration of the present embodiment, and the CPU 1 is required in this music information input device based on a program etc. stored in advance in the ROM 2 and data temporarily stored in the RAM 3 etc. Execute all controls that The ROM 2 stores, together with the program, image data of various symbols necessary for musical scores such as various notes, staffs, clefs, key signatures, and time signatures.

The LCD controller 4 includes a CPU 1
The LCD display unit 5 is driven in accordance with the instruction to display the staff, notes, and the like, and the change display processing of the score composed of the staff, notes, and the like is executed. A touch panel 6 is laminated on the upper surface side of the LCD display unit 5, and touch information on the touch panel 6 is input to the CPU 1 via a panel I / O port 7. Sound source 8 is CPU
The musical tone waveform is generated according to the instruction No. 1, and the musical tone waveform is amplified by the amplifier 9 and emitted from the speaker 10.

FIG. 2 shows the external structure of the music information input apparatus according to this embodiment. The apparatus main body 11 has a screen 12 formed by stacking a touch panel 6 on the LCD display section 5. It is provided. At the bottom of the screen 12, switches 13 and 14 used for turning on / off the device and adjusting the brightness of the LCD display unit 5 are arranged, and LEDs 15 and 16 corresponding to the switches 13 and 14 are arranged.
Are arranged. On the side of the switch 14, the speaker 10 is built in, and a pen 17 provided separately from the apparatus main body 11 is prepared.

Next, the operation of this embodiment having the above configuration will be described. That is, the CPU 1 starts the operation according to the main flow shown in FIG. 3 when the switch 13 is turned on. Then, first, the LCD controller 4 is controlled based on the image data of the musical notation read from the ROM 2,
The staff notation is displayed on the CD display unit 5 (SA1). This S
By the process of A1, a plurality of staffs are displayed on the screen 12.

Next, it is determined whether or not there is a clef input operation (SA2). Here, the clef input operation is, for example, the operation of drawing "o" on the staff using the pen 17 described above. When the input person draws “◯” on the staff using the pen 17, the touch of the pen 17 at the time of drawing is detected by the touch panel 6 and input to the CPU 1 via the panel I / O port 7. Then, the CPU 1 determines that there is a clef input operation, reads the image data of the treble clef from the ROM 2, controls the LCD controller 4, and executes clef display (SA3). Depending on the processing of this SA3, L
By the operation of the CD controller 4, a treble clef is displayed at the end of the staff drawing the "O".

Next, it is determined whether or not there is a time signature input operation (SA4). This time signature input operation is, for example, an operation of writing the numerator and denominator numbers of the time signature on the staff using the pen 17. So, for example, if it is 3/4,
Write "3" at the top and "4" at the bottom. As a result, a touch is detected by the touch panel 6 and a numeric value is input to the CPU 1 via the panel I / O port 7. Then, the CPU 1 recognizes the two numbers written above and below based on the number data stored in the ROM 2 and determines that the tone sign input operation has been performed, and executes the time signature display (SA5). ). That is, the image data of the corresponding numeral is read from the ROM 2, and the LCD controller 4 operates according to the read image data, whereby the tone symbol "3/4" is displayed (see FIG. 6).

In this way, after the determination processing of SA1 to SA5 is executed, the next pen operation processing (SA6) is performed. This pen operation processing is executed according to the flowchart shown in FIG. 4, and first, the pen operation determination is performed (SB
1). In this pen operation determination, it is determined whether the operation performed on the screen 12 by the pen 17 is a “note input operation”, an “addition operation”, an “edit operation”, or an “end operation”. Here, the “note input operation” means an operation of inputting a note by hand with the pen 17 on the displayed staff, or by specifying a pitch on the staff and then specifying a note length by a numerical value. Is an operation for inputting.

When such a note input operation is performed, the note input operation is detected and input based on the touch signal of the pen 17 input from the touch panel 6 through the panel I / O port 7. Display notes (SB
2). Subsequently, it is determined whether or not there is a note input for one bar in the time signature (SB3), and the loop of SB2 → SB3 is repeated until the note input for one bar is input. Therefore, during this time, by performing a note input operation on the staff, the input note is displayed every time the process of SB2 is executed. When a note for one bar is input, the bar line is automatically drawn (SB4).
By the processing of 4, the bar line is displayed after the last note for one bar.

Subsequently, it is judged whether or not there is a note input for one step (SB5), and until a note input for one step is received,
The loop of SB2 to SB5 is repeated. Therefore, this SB
By repeating the loop of 2 to SB5, the notes input during this period are sequentially displayed, and the bar line is displayed at the time when there is a note input of one bar. And
If there is a note input for one step, proceed from SB5 to SB6,
Determine whether or not there is a music score completion operation.

The completion operation of this musical score is an operation of writing a line in parallel with the bar line that is automatically drawn last by the operation of the pen 17. And such a pen 17
If there is no operation by, the clef and key signature are automatically displayed at the beginning of the next stage (SB8), and the process from SB2 is repeated. Therefore, until the completion operation is done,
The loop of SB2 to SB8 is repeated, the notes input during this are sequentially displayed, the bar line is displayed when there is one bar of note input, and the bar is displayed when there is one row of note input. By changing the stage, the clef etc. is automatically displayed. Then, when the completion operation is performed, SB6 to S
Proceeding to B7, the end line is drawn, and by the processing of SB7, the end line is displayed at the last part of the final stage.

On the other hand, when it is determined that there is an "editing operation" when the pen operation determination is made in SB1,
Go from SB1 to SB9. Here, "editing operation" means
The operation of writing a numerical value on the screen 12 by operating the pen 17,
It is an operation to specify a range with parentheses, an operation to write a symbol, or an operation to write a character. Then, if there is any of these operation modes, the contents are judged at SB9, and any one of the processes 1 to 4 is executed according to the judgment result (SB10 to SB13).

That is, in the processing 1 (SB10) when the content of the editing operation is "numerical value", the position where the numerical value is written is recognized on the displayed musical score. Further, the recognized number is recognized as well as the symbol written before the recognized numerical value. Next, after performing the processing according to the position of the numerical value, the symbol, and the recognition result of the numerical value, the display is switched based on the display data generated by this processing.

More specifically, the contents of this processing 1 will be described. For example, in the state where the quarter note of the pitch F1 is displayed, the operation of the pen 17 causes "÷ 2" after the note.
First, it is recognized that the position of the numerical value "4", that is, the numerical value "4" is after the quarter note of the pitch F1. Next, the symbol “÷”, which is the symbol before the numerical value “4”, is recognized, and the numerical value “4” is recognized. Then, based on these recognized results, the note length of the quarter note of the pitch F1 is divided by "4" to obtain the 16th note of the pitch F1. Next, the quarter note of the pitch F1 to be changed is erased, and the display switching is performed to display the sixteenth note of the pitch F1.
The quarter note is changed and displayed as a sixteenth note with the same pitch.

Further, in the processing 2 (SB11) when the content of the editing operation is "parentheses", the range enclosed by the parentheses on the displayed musical score is recognized. Then, the figure drawn next is recognized, and it is determined whether or not the recognized figure is "x". Then, if the recognized figure is "x", the area recognized in SD1 is erased. However, if the recognized figure is not "x", it is determined whether it is """, and if it is"", the value in the parenthesis is copied into the parenthesis.

The contents of this process 2 will be described more specifically. For example, when a quarter note having a pitch E1 is displayed, if the note is enclosed in parentheses, the range within the parentheses is recognized. Further, when an X mark is entered in the parentheses, this is recognized, the range within the parentheses is erased, and the displayed quarter note of the pitch E1 disappears. If you enclose the measure in parentheses,
If the range for one bar within the brackets is recognized and the cross mark is entered in the brackets, this is recognized and the note for one bar disappears.
Furthermore, when notes are displayed over multiple levels and multiple measures, if you first specify the range by enclosing the upper measure with parentheses, the range for one measure in parentheses will be recognized, and then the lower range will be recognized. If you specify a range by writing """on the staff notation, all the notes in the upper brackets will be copied to the lower brackets.

Further, in the processing 3 (SB12) when the content of the editing operation is "symbol", first, the graphic of the symbol is recognized and it is determined whether or not the symbol is open upward. Then, in the case of upper opening (∨), one note or one bar is opened between them, thereby forming a blank area on the staff corresponding to the symbol. However, if the symbol is a downward opening (∧), the process of closing the gap is executed and displayed.

Further, in the processing 4 (SB13) when the content of the editing operation is "character", the input character is recognized,
Display data according to the recognition result. That is, pen 1
For example, "Mode" is added to the top of the desired bar by the operation of 7.
When you input the character, the input character is recognized,
Data "Modeler" corresponding to the recognized "Mode"
"ate" is displayed. Also, "All" is displayed at the top of the bar.
If there are multiple candidates for "Alle", such as when entering the letter "e", all candidates "Alleg"
retto Allegro Allegrissim
“O” is displayed. When one of the candidates is selected by operating the pen 17, the selected candidate is displayed at the position where the character is input.

On the other hand, when it is determined that there is an "additional operation" when the pen operation determination is made in SB1,
Go from SB1 to SB14. Here, the “editing operation” is an operation of adding any one of a stick, a flag, a note point, and a black circle to the note already displayed on the screen 12 by operating the pen 17. If there is any of these operation modes, the operation is started according to the flowchart shown in FIG. 5, and the added contents are the stick, the flag, the mark point,
It is determined which one of the black circles is (SC1). Subsequently, the data of the original note that has been additionally operated is changed according to the determination result (SC2 to SC5).

That is, for example, when a bar is added to the displayed whole notes, the whole note data is changed to the half note data, and when the flag is added to the quarter note, the quarter note is added. If the data of is changed to the data of the eighth note, and the point is added to the quarter note, the data of the quarter note is changed to the data of the quarter note and the white circle of the half note is filled. When a black dot is added, the data of the half note is changed to the quarter note. Further, the display is changed based on the changed data (SC6), and the note to be added by the process of SC6 becomes the note of the pitch corresponding to the changed data in each step of SC2 to SC5. Change.

Next, it is judged whether or not the bar line is drawn, that is, whether or not the display of the note within the bar that has been established as one bar due to the bar line being already drawn is changed (SC).
7). As a result of this determination, when the display of the note at the part where the bar line is not yet drawn is changed, it does not occur if the number of beats in the measure does not correspond to the time signature even if the note is changed, so it will be described later. The determination process is unnecessary and the process goes to the end. However, when a bar line is already drawn and a note in a bar that has been established as one bar is changed, the number of beats in the bar may not correspond to the time signature.

Therefore, when the note within the bar established as one bar is changed, it is determined whether or not the note within the bar corresponds to the time signature (SC).
8). As a result of this determination, if the note in the measure does not correspond to the time signature, the display color of the measure is changed to a color different from the others (SC9). Then, the process waits until a new addition or note input is made (SC10), and when there is a new addition or note input, the determination process from SC6 is executed. And if this new addition or note input makes the notes in the bar correspond to the time signature,
When the determination process from SC6 is executed again, the determination in SC8 becomes YES. Therefore, the process proceeds from SC8 to SC11 to restore the display color of the bar, and then proceeds to END to end the additional operation detection / display process.

The additional operation detection / display processing will be specifically described. That is, while the score shown in FIG. 6A is displayed on the screen 12, FIG.
As shown by the dotted line in FIG.
Suppose you have added a "flag" to the quarter note. Then SC1
Then, it is determined that the added content is a flag, and if the flag is added to the quarter note, it is an eighth note, so the data of the quarter note is changed to the data of the eighth note in SC3. Further, the display is changed based on the changed data in SC6, so that the quarter note of the pitch F1 is displayed as the eighth note of the same pitch, as shown in (C) of the same figure. Change. Further, since the eighth note of the pitch F1 of which the display is changed is the note within the bar which has been established as one bar because the bar line has already been drawn, the determination at SC7 is YES. Therefore, the process proceeds to SC8, and it is determined whether or not the notes in the measure correspond to the time signature.

At this time, since the displayed score is 3/4 beat, and the measure is less than half beat relative to 3 beat, the determination at SC8 is NO, and the processing at SC9 results in (C) of FIG. As indicated by the slanted lines, the display color of the bar is changed to a color different from the others. Then, in this state, as shown in (D) of the same figure, when the note point P is added to the quarter note of the pitch G1, the determination in SC10 is YES, and SC6
Is executed, the quarter note of pitch G1 is changed to the note point quarter note of the same pitch in SC4. Further, since this change is also within the bar in which the bar line has already been drawn, the process proceeds from SC7 to SC8, and it is determined whether or not the notes in the bar correspond to the time signature. At this point, there are 3 beats of notes in the measure, which correspond to the time signature.
The determination in SC8 is YES, and in SC11, the bar display color is returned to the original color, and as a result, as shown in (E) of the figure,
The bar has the same display color as other bars. If an eighth note is input without adding the note point P, the newly input note is displayed in the display change process of SC6. Then, when an eighth note is input in this way, the note of the measure corresponds to the time signature. Therefore, in this case as well, the determination at SC8 is YES, and at SC11, based on the display color of the measure. Returning, the bar has the same display color as other bars.

As described above, when the musical score input operation, the editing operation, or the addition operation is performed to complete the creation of the musical score, and then a predetermined ending operation is performed, the process proceeds from SB1 to SB15 in FIG. All data that make up the score is R
It is saved in AM3. Further, the speaker 10 is controlled by controlling the sound source 8 based on the saved data.
Generates a musical sound composed of the saved score.

[0032]

As described above, according to the present invention, the notes on the musical score are displayed and changed in accordance with the mode of the addition operation of the handwriting operator to the notes on the displayed musical score. Therefore, it is possible to freely rearrange the musical notes of the musical score input and displayed by the operation of the handwriting operator and the musical notes of the musical score input and displayed by another operation. Further, when the number of beats of the measure to which the note belongs is inconsistent with the time signature by changing the display of the note, the measure is displayed in a display state different from that of other measures. Therefore, it is possible to clearly recognize the bar in which the beats do not match due to the change, and thereby the score can be created without error.
