The present invention relates to a sheet music shifting crime prevention that can be automatically changed to an arbitrary set for one song played when playing an electronic keyboard musical instrument such as a digital piano, and the like. The present invention relates to a method for transferring sheet music for an electronic keyboard musical instrument improved from patent application No. 17111.

In general, when composing and arranging a predetermined piece of music, the composition and arrangement of contents are separately recorded on a stave while playing a musical instrument. However, in case of such recording work, the important parts are often forgotten or distorted, and they are often unsatisfactory. But the corrective work is very inconvenient, and had a lot of time.

Therefore, in 1988 Special Application No. 17111, which was filed by the applicant, automatically detects and displays the music played as the user plays the electronic keyboard musical instrument. There was a problem such as having to play the electronic keyboard instruments again.

The present invention has been devised to solve the above-mentioned conventional problems, and when composing the electronic keyboard musical instrument, it is convenient to compose and arrange the jaws even if the jaws are not played again without changing the jaws. In addition, the purpose of the present invention is to provide a method for translating musical scores for electronic keyboard musical instruments, which makes it possible to easily transpose information without knowing the scale and chords, since the information on each synthesized note can be recognized at a glance. It explains in detail.

2 is a time flow diagram showing the sheet music shifting method of the present invention, as shown in the first step of generating a corresponding keycode and keyon signal when the first half is pressed, and according to the keyon signal of the first step. A second process of correcting an error by counting a tempo clock and comparing the length of the standard sound, a third process of converting the error value corrected in the second process into note and comma information, and an error in the second process A fourth process of judging nodes and generating node pulses by sequentially calculating the modified coefficient values; a fifth process of generating node numerical information by accumulating the node pulses of the fourth process; and the key code of the first process. A sixth step of storing the notes and the comma information of the third step and the numerical value information of the fifth step; and a seventh step of deleting duplicate nodes from the data stored in the sixth step and adding appropriate symbols. , The sixth and 7 consists of a process of claim 8, and the sixth and the ninth process, a tenth process of storing again transpose the stored data twos selected by the user to print the data stored in the 7th step of displaying the data stored in the process.

According to the score display device and display method of the present invention as described above, when the user presses a key, the keyboard unit 1 displays whether a key code, which is key information corresponding to the pressed key, and a key suitable for the corresponding keyboard are pressed. Generates a key-on signal.

The sound generator 2 generates a musical sound based on the key code and the key-on signal generated by the keyboard unit 1, and the generated sound signal is generated by the rhythm generator 5 through the amplifier 3. It is mixed with the rhythm, and this mixed signal is transmitted as sound to the user or listener through the speaker 4.

In addition, the rhythm generator 5 is used for the automatic rhythm performance, and outputs a variety of rhythm patterns corresponding to the rhythm selected by the rhythm selection switch in its own time in accordance with the tempo clock generated by the tempo clock generator 6.

On the other hand, the key-on signal generated from the keyboard unit 1 is applied to the sound length detector 7. Another input of the note length detector 7 is applied to the tempo clock generated by the tempo clock generator 6. The note length detector 7 counts the tempo clock from the key-on time to generate length data for the note, and then turns off the key. The tempo clock is also counted when generating the length data for the comma.

This note data is added to the note length corrector 8, where the coefficient value (including the error) corresponding to the note length is adjusted and output to the standard note length.

For example, if the standard note coefficient value of the quarter note is 32, the actual coefficient value 30 or 34 degrees including the error is corrected to 32, so that the length data value corresponding to the quarter note is 32.

으로 구성된다는 기호등에 대한 정보)로 변환되어져 키보드부(1)에서 늘리어진 건반에 대응하여 출력되어진 키코드와 함께 악보데이타 메모리(10)에 가하여진다.The note length data generated by the note length corrector 8 is added to the note / comma information converter 9, where note and comma information (e.g., eighth note ♪) representing a predetermined note / comma corresponding to the note data is ♪,

Information on the symbol and the like, and is added to the sheet music data memory 10 together with the key code outputted in response to the keyboard extended by the keyboard unit 1.

The measure end detector 12 sequentially accumulates the input sound length data and outputs a measure pulse to the measure counter 11 when the pre-selected measure value is reached.

For example, when a note length coefficient value of 32 per quarter note is 32, a node pulse is generated when the total value of the note length coefficient reaches 128 (4 × 32) in the score of 4/4 time.

The measure counter 11 calculates an input measure pulse and applies numerical information corresponding to the calculated value to the sheet music data memory 10.

The score data memory 10 sequentially stores the previous note / comma information and key code, and also stores numerical information corresponding to the measure number.

It is assumed that the memory capacity of this score data memory 10 is usually fast, so that it is possible to store all information about a song of about 20 minutes (about 1 M bit or more).

The music score data memory 10, the dome adder 15, the indicator 18, the printer 17, and the ear controller 18 are appropriately selected and controlled by the operation of the mode switch 13.

That is, when a mode such as a display code, an edit mode, etc. is selected by the mode switch 13, a signal corresponding to the selected mode is applied to the mode controller 14. The mode controller 14 controls the music data memory 10, the dome adder 15, the display drive control unit 19, and the print drive control unit 20 based on the signals input from the mode switch 13, respectively. Apply a signal.

When the display mode is selected in the mode switch 13, the mode controller 14

Denotes a control signal to the sheet music data memory 10, the display drive control unit 19 and the print drive control unit 20.

The musical score data memory 19 memorizes the numerical information corresponding to the note / comma information, the key code, and the node signal input according to the keyboard performance, and selectively outputs each input information.

The display drive control unit 19 displays the score on the display unit 18 based on the information output from the score data memory 10 so that the note is displayed on the stair, and shifts each note to the left along with the display of the new note. Representing the music, the print drive controller 20 drives the printer 17 to print the music stored in the music data memory 10.

Next, the case where the edit mode is selected in the mode switch 13 will be described. First, the mode controller 14 applies a control signal to the dodol symbol adder 15.

The dodol symbol adder 15 edits information on one piece of music stored in the music data memory 10, deletes duplicated information in units of measure, and simultaneously adds a dodol symbol as appropriate.

That is, the doubly code adder 15 reads out the last measure information stored in the score data memory 10 in measure units, and sequentially compares the information in units of measures in the first direction of the song.

When duplicated information is detected in this manner, the previous section information of the last section is compared with the section information immediately before the section where the same information is detected.

Therefore, it is detected that the last two nodes are the same as the previous two nodes, but the node information corresponding to the same node is erased, and at the same time, a table is added before the previous node information and at the end of the node information.

In this case, when processing information in units of measure, the measure value information corresponding to the measure number is used.

The pairing unit 16 changes the group of the sheet music stored in the sheet music data memory 10 and changes the group by obtaining a difference between the current group and the selected group according to the control of the mode controller 14, and changes the group according to each note and the selected group. The SF signals are compared and changed and stored in the score data memory 10.

The information re-edited as described above is newly displayed by the operation of the mode switch 13, and is printed by the printer 17 at the same time.

, coda)를 부가 할 수 있다.In addition, in the previous embodiment,

In the case of using a simple repetition symbol such as), depending on the overlapping state of nodes, the elimination of duplicate nodes and various dodol symbols (DS,

, coda) can be added.

On the other hand, Figure 2 is a signal flow diagram showing a sheet music shifting method of the present invention. As shown in the drawing, when the user presses a key, the key is decoded to generate a key code and a key on signal. The tempo clock is counted according to the generated key-on signal, and the error is corrected by comparing the counted value with the length of the standard sound. That is, if the count value and the standard sound length are not the same, there is an error. The error is corrected by changing the length, and the corrected coefficient value is converted into information of notes and rests.

And while calculating the error value corrected by the coefficient value sequentially compared to the node value, if the two values are the same, and generates a node pulse, and the generated node expansion generates node numerical information.

All data for one song, i.e., keycode (KC), notes and rests, and MIDI numerical information are memorized, and the last uncompared measure is repeated by measure in the first direction of the song. While deleting the node, an appropriate repeat symbol is added, i.e., a dorl symbol is added and stored, and the data of the stored song is displayed on the indicator 18, and printed by the printer 17.

On the other hand, when explaining the automatic transposition mode of the sheet music transposition method of the present invention, when the transposition mode is pressed by the mode switch 13 and the group to be changed is selected by the mode switch 13 is stored in the sheet music data memory 10 Find the first pair and the selected pair and difference (GAP).

) 다음에 조를 표시한다.Once the difference (GAP) is found, the key code (KC) is subtracted to change the key code (KC) by subtracting the difference (GAP), and each note is moved to the right, that is, from the first note of the song to the end of the song in sequence. After moving according to the key code (KC) changed by the difference from the original negative position to make an area to display the selected jaw, the shop (#) and flat (b) symbols representing the selected jaw are obtained from the key table. The shop (#) and the flat (b) representing the set of the table contain position information about the rows and livers located in the staff, and generate SF signals, which are shop (#) or flat (b) signals. , Based on the generated SF signal

) Then the pair is displayed.

For example, in the case of D major, shops (#) are displayed in the third and fifth lines as shown in FIGS. 3c and 3d.

The shop (#) is set to -1 and the flat (b) is set to +1, which is sequentially compared with the SF signal obtained from the first table of the song. If the comparison note and the SF signal are the same, the shop (#) After adding and storing #), the operation of moving to the next note is repeated until the last note, and the data about the synthesized song is stored in the sheet music data memory 10 again, thereby printing the printer 17 and the display 18. To print and display.

In addition, Figs. 3a-d show the process of making the transition as four word scores. Fig. 3a is the first major song, and C. 3b is the difference between the group (D) to be changed and the first group (GAP = 2). Figure 3c shows D major in the first section of the song, and figure 3d shows the final transposition chart.

As described above, the sheet music shifting method of the present invention is capable of automatically shifting the music of the sheet music so that when the electronic keyboard musical instrument is played, the music can be easily transposed even if the music is not played again. Not only is it convenient for you, but you can also see the information on the synthesized notes at a glance, and there is an effect that you can easily and easily move the chord without the knowledge of the scale and the chord.
