DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0020]
(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of an electronic musical instrument to which the automatic performance device according to the first embodiment is applied. In FIG. 1, a CPU 10, a ROM 11, a RAM 12, a keyboard scan circuit 15, and a tone generator 17 are connected to a bus line 20 such as a data bus and an address bus, respectively, so that data can be transmitted and received between them. .
[0021]
A keyboard 16 is connected to the keyboard scan circuit 15. The keyboard 16 is composed of one or a plurality of keys including a plurality of keys and a key switch provided corresponding to each of the keys. The keyboard scanning circuit 15 is configured to detect the key press and release of the keyboard 16 according to the state of the key switch and also to detect the operation speed of the key. In the automatic performance mode, an arbitrary key on the keyboard 16 is used to instruct reading of automatic performance data, and every time the performer presses an arbitrary key, the performance data is sequentially read out by a predetermined amount. Automatic performance is executed.
[0022]
The operation panel unit 13 and the external I / F 14 are connected to the CPU 10. In addition to various operators for setting tone color, volume, effect, rhythm, etc., the operation panel unit 13 is used for performing automatic performance based on automatic performance data (selection of performance data, tempo setting). Etc.), a display for displaying various setting states by the above-described various operators, and a navigation display of the key pressing timing, and the like are arranged. The external I / F 14 is configured by a MIDI interface or the like.
[0023]
The CPU 10 controls the entire electronic musical instrument according to the control program stored in the ROM 11 while using the RAM 12 as a work memory. For example, in the manual performance mode, the scanning process of each key switch of the keyboard 16 and the scanning process of each operator of the operation panel unit 13 are performed, and the operation state of each key on the keyboard 16 (key depression, key release, operation is performed). The key switch number (key number) of the key, the velocity relating to the operation speed of the key, etc.) and the operation state of each operation element on the operation panel unit 13 are detected and supplied to the sound source unit 17 so that each key or each operation element Performs sound generation processing according to the operation.
[0024]
Further, in the automatic performance mode, the CPU 10 sequentially reads out the automatic performance data selected by the switch provided on the operation panel unit 13 by a predetermined amount from the ROM 11 every time any key is pressed, and reads it out as a sound source unit. The corresponding musical tone signal is formed and output by supplying the signal to 17. At the same time, based on the read automatic performance data and tempo data, a process of displaying a key pressing timing guide and lyrics on the display on the operation panel unit 13 is also performed.
[0025]
The ROM 11 stores automatic performance data used when performing an automatic performance as several types of preset data, in addition to a program storing various processing procedures of the CPU 10. Further, musical tone waveform data such as PCM used when the musical tone data is formed by the sound source unit 17 is also stored. The RAM 12 has a storage area for temporarily storing various necessary data during the program execution process of the CPU 10 and for storing data obtained as a result of various processes. User data generated by freely editing preset automatic performance data in the ROM 11 is also stored in the RAM 12.
[0026]
The sound source unit 17 includes a plurality of tone generation channels and is configured to generate a plurality of tone sounds simultaneously. The tone generator 17 reads PCM musical sound waveform data from the ROM 11 based on key number information (note information) representing each key sent from the CPU 10, musical tone parameter information set by operation of each operator, and the like. After the amplitude and envelope are processed, the set effect is applied to form digital musical tone data.
[0027]
The digital musical tone data formed by the tone generator 17 is converted into an analog musical tone signal by a D / A converter (not shown) in the tone generator 17. The musical sound signal is amplified by the amplifier 18 and then given to the speaker 19 to be emitted.
[0028]
FIG. 2 is a diagram showing an example of navigation display on the display provided in the operation panel unit 13. In the present embodiment, as the display 21 shown in FIG. 2, a bitmap liquid crystal display capable of drawing arbitrary characters, symbols, images, etc. in dot units is used. The display is larger than the conventional display 101 shown in FIG.
[0029]
In the present embodiment, the liquid crystal display 21 displays the key pressing timing relating to the automatic performance data of the length of four quarter notes as a black circle (●) 22 and also the automatic performance of four quarter notes. The lyrics corresponding to the data are displayed. At this time, as for the key pressing timing, the key pressing timing of the first beat, the second beat,... From the left to the right of the liquid crystal display 21 is indicated by the position of the black circle 22 as in the conventional case. As for the lyrics, the corresponding lyrics are displayed left justified.
[0030]
FIG. 2 shows an initial state displayed when certain automatic performance data is selected and automatic performance is started. In the initial state, all key pressing timings are indicated by black circles 22. Thereafter, when the automatic performance is started by pressing the key, the display of the black circle 22 at the corresponding timing is switched to the cross mark (+) every time the key is pressed. When the key is actually executed according to the last key pressing timing currently displayed, the display is switched to a new navigation display (including lyrics) corresponding to the next automatic performance data. It should be noted that such switching is not performed when there is no subsequent automatic performance data.
[0031]
The navigation display as described above is performed based on the automatic performance data read from the ROM 11 or RAM 12 of FIG. As described above, the automatic performance data in the ROM 11 is preset data, and the automatic performance data in the RAM 12 is user data. As shown in FIG. 3, all of them are bar marks, beat marks, lyrics data, note data, and end data. It consists of a sequence of marks.
[0032]
Here, the bar mark is information indicating bar breaks, and includes time information indicating how many minutes the automatic performance data has. This time signature information may change in the middle of one automatic performance data. The beat mark is information indicating a break between beats. The lyric data has lyrics information in the form of text data, for example.
[0033]
In addition, note data includes key numbers for identifying the pitches that make up the performance sound, velocity indicating the volume of the sound, step time indicating the sounding timing from the bar mark or beat mark, gate time indicating the sounding time, etc. Become. The end mark is information indicating the end of the automatic performance data.
In addition to these, depending on the performance data, repeat end information including a repeat mark indicating a repeat point is included.
[0034]
In the following, an operation when performing navigation display based on such automatic performance data will be described. The CPU 10 in FIG. 1 reads the automatic performance data as shown in FIG. 3 in order from the top as pointers 0, 1, 2,. When the note data is read, a black circle 22 is displayed at a position advanced to the right by a distance corresponding to the step time from the position of the previous bar mark or beat mark based on the step time in the note data. When the lyrics data is read, the lyrics are displayed following the previously displayed lyrics. In the initial state, the navigation display as shown in FIG. 2 is performed by performing such an operation for one line (one bar).
[0035]
Note that the position of the immediately preceding bar mark corresponds to the left end of the liquid crystal display 21. The position of the immediately preceding beat mark corresponds to any position obtained by equally dividing the length direction of the liquid crystal display 21 in accordance with the time signature information included in the bar mark. For example, in the case of automatic performance data having a time signature of half, the position of the beat mark corresponds to one central position that bisects the length direction of the liquid crystal display 21. Further, in the case of automatic performance data having a time signature of a quarter, the position of the beat mark corresponds to three internal dividing points among the length directions of the liquid crystal display 21 divided into four equal parts.
[0036]
Thereafter, when the performance is actually started, the CPU 10 performs a process of switching the display of the black circle 22 indicating the key pressing timing at that time to the cross mark (+) every time the key is pressed. Further, it is determined whether or not the timing at which the key is pressed corresponds to the last timing currently displayed by navigation. If this is the case, the process of switching the navigation display to the next line as described above is performed. Do.
[0037]
In this embodiment, the automatic performance by pressing the key, the navigation display, and the lyrics display are both performed based on the automatic performance data read from the ROM 11 or RAM 12, but the read pointer on the automatic performance data is used for performance. Two-way management is performed using a pointer and a display pointer.
[0038]
That is, in the initial state before the performance starts, the performance pointer is at the head (pointer 0) since the performance has not yet started. On the other hand, since the navigation display has already been performed for one measure even in the initial state, the display pointer remains ahead of the performance pointer by one measure.
[0039]
Thereafter, when the performance is actually started, the display pointer remains at the same place, but the performance pointer is gradually advanced each time the key is pressed. When a key is pressed at the last timing currently displayed for navigation, the display pointer is further advanced by one bar from there, and the navigation display is switched to the next one line at a time. .
[0040]
As described above, in the present embodiment, the display provided on the operation panel unit 13 can display a bitmap, and the liquid crystal display 21 that is larger than the conventional one is provided, and the key depression having a length equivalent to four quarter notes is provided. Along with the timing guide display, the corresponding lyrics are also displayed. As a result, when a performer sings a song in accordance with his / her own automatic performance, both the key press timing guide display and the lyrics can be viewed at once without changing the line of sight, and the song and performance can be viewed at once. Both can be easily performed.
[0041]
(Second Embodiment)
Next, a second embodiment of the present invention will be described. The configuration of the electronic musical instrument in the present embodiment is the same as that shown in FIG. 1, and the configuration of automatic performance data used during automatic performance is also the same as that shown in FIG. It should be noted that the configurations of the electronic musical instrument and the automatic performance data are the same in other embodiments described later.
[0042]
FIG. 4 is a diagram showing an example of navigation display on the liquid crystal display 21 in the present embodiment. In the present embodiment, the lyrics 41 are displayed instead of the note navigation display indicated by static black circles as shown in FIG. Then, the ball (●) 42 is shown to move while bouncing on the lyrics 41 in synchronism with the performance (key depression) by the performer.
[0043]
The lowest point of the trajectory along which the ball 42 moves is a portion directly above the character to be uttered simultaneously with the key depression, and the highest point is a central portion between two adjacent lowest points. The example in FIG. 4 is automatic performance data in which each word constituting the lyrics 41 is uttered every time a key is pressed. Therefore, the ball 42 moves by bouncing with the beginning of each word as the lowest point. I will do it. Further, the moving speed of the ball 42 at this time is determined based on the selected automatic performance data and tempo data. Such a navigation display indicates that the player should press the key at the moment when the ball 42 reaches the lowest point, and which part of the lyrics should be sung when the key is pressed.
[0044]
FIG. 5 is a block diagram showing a functional configuration for realizing the navigation display as described above. Actually, for example, the CPU 10 in FIG. 1, a program stored in the ROM 11, a RAM 12 as a work area, and the like are configured. Is done. The navigation display function shown in FIG. 5 is executed based on the performance pointer and the display pointer on the automatic performance data managed in a binary manner.
[0045]
In FIG. 5, a performance data reading unit 51 sequentially reads data for one line to be collectively displayed on the liquid crystal display 21 from the automatic performance data stored in the ROM 11 or RAM 12 in accordance with the progress of the display pointer. . The lyric display unit 57 displays the lyric 41 for one line based on each lyric data included in the read automatic performance data for one line.
[0046]
The jump distance calculation unit 52 confirms the number of characters constituting one lyric data based on each lyric data included in the read automatic performance data for one line, and makes one jump distance of the ball 42 Is calculated for each lyric data. Here, as shown in FIG. 3, the lyrics data corresponding to one note data is one lyrics data.
Further, the jump height calculation unit 53 checks the number of characters constituting one lyric data in the same manner as described above, and at what number the character 42 should be displayed at what height from the lowest point. Kika is calculated for each lyric data. For example, the jump height of the ball 42 is divided into five levels from the lowest point to the highest point, and what level of the character is displayed at what level, or how many characters are displayed at the level of each level. Calculate what to do when.
[0047]
The jump speed calculation unit 54 is based on each note data included in the read automatic performance data for one line and tempo data set by a tempo setting switch (not shown) on the operation panel unit 13. The speed at which the ball 42 moves in one jump (or the movement time in one jump) is calculated for each piece of note data.
[0048]
For example, as in the example of FIG. 4, note data is included in each beat, and performance data whose sounding timing is the beginning of each beat is included in the bar mark in the note data. Each jump speed can be calculated from the time signature information and the set tempo data. Also, when multiple note data are included in one beat, the difference in pronunciation time between the two note data is obtained by taking the difference between the step times included in adjacent note data. Can do. Therefore, it is possible to calculate one jump time from this sounding time difference and tempo data.
[0049]
The values calculated by the jump distance calculation unit 52, the jump height calculation unit 53, and the jump speed calculation unit 54 as described above are temporarily stored in a memory (not shown). Based on the signal sent from the keyboard scan circuit 15 in FIG. 1, the key depression determination unit 55 determines whether or not any key has been depressed, and the ball movement display unit 56 indicates that the key has been depressed. To tell.
[0050]
The ball movement display unit 56 executes the jump display of the ball 42 corresponding to the key depression only once based on the data held in the memory (not shown) according to the performance pointer when the key is depressed. When the key is depressed every time the ball 42 reaches the lowest point, a navigation display is made such that the ball 42 moves sequentially while bouncing on the lyrics 41.
[0051]
In the above example, the jump distance, height, and speed of the ball 42 are calculated in advance for one line according to the progress of the display pointer, and each time a key is pressed, they are sequentially read according to the performance pointer to display the jump display. An example of execution is shown. On the other hand, the jump distance, height, and speed of the ball 42 may be calculated sequentially according to the performance pointer each time a key is pressed.
[0052]
As described above, in the present embodiment, the lyrics 41 are displayed instead of the static note navigation display, and the ball 42 is displayed so as to move while bouncing on the lyrics 41 in synchronization with the performance. . Then, the key should be executed when the ball 42 moving on the lyrics 41 reaches a predetermined position (the lowest point of the jump), and which part of the lyrics should be sung when the key is pressed. Is navigated.
[0053]
Thereby, the key pressing timing can be easily grasped by observing the movement of the ball 42, and the player can easily grasp the key pressing timing. Since lyrics are also displayed in the same manner as in the first embodiment, when the performer sings a song in accordance with his / her automatic performance, the line of sight is changed between the key press timing guide display and the lyrics. You can see both at once without looking alternately. In addition, the movement of the ball 42 makes it clear which lyrics should be sung now, and both the song and the performance can be easily performed.
[0054]
(Third embodiment)
In the second embodiment, when the ball 42 is moved on the lyrics 41, the jump distance and the jump height are calculated by looking at the number of characters in the lyrics data. However, in this case, for example, as shown by * in the performance data as shown in FIG. 6, the number of characters is “0” at the position where there is a note but no lyrics, so the jump distance and the jump height are set. It cannot be calculated and the ball 42 will remain at its lowest point. Therefore, in this case, there is an inconvenience that the next key pressing timing cannot be grasped.
[0055]
The third embodiment is for eliminating such inconvenience. FIG. 7 shows an example of navigation display on the liquid crystal display 21 in the present embodiment. In this embodiment, as shown in FIG. 7, when navigating and displaying the ball 42 while moving on the lyrics 41 in synchronization with the performance, there are notes (note data) but no lyrics. At the position, the ball 42 is caused to jump vertically on the spot.
[0056]
That is, in the example of FIG. 7, if the key is pressed at the timing when the ball 42 moves on the second “Where” from the left, the jump distance calculated from the number of characters corresponding to “Where” + one blank character, etc. Based on the above, the ball 42 moves toward the third “oh”. Then, it is sufficient to press the key again when the ball 42 reaches the “oh”. Note data corresponding to the key pressed at this time is “Where” and “oh” as shown in FIG. Corresponds to data (*) with no lyrics between.
[0057]
Therefore, in this case, the ball 42 is caused to jump vertically right above the character “oh”. The jump speed at this time is calculated from the difference between the step time included in the note data corresponding to the note without the lyrics and the step time included in the note data corresponding to the next “oh” note, and the tempo data. Is done. Next, when the key 42 is depressed at the timing when the ball 42 that has jumped vertically again falls directly above the character “oh”, this time, the jump distance calculated from “oh” + the number of characters for one blank character is set. Originally, the ball 42 moves toward the fourth “where”.
[0058]
As described above, according to the present embodiment, when navigating and displaying the ball 42 by moving it over the lyrics 41, the ball 42 jumps on the spot even if there is a note but no lyrics. Then, the next key pressing timing can be surely known.
[0059]
(Fourth embodiment)
The fourth embodiment shows another example for solving the disadvantage of the second embodiment in which the ball 42 stops at a position where there is a note but no lyrics. In the present embodiment, at a position where there is a note but no lyrics, an arbitrary mark or character is automatically inserted and displayed as a part of the lyrics to cause the ball 42 to jump.
[0060]
That is, in the performance data of FIG. 6, for example, there is a note without lyrics between “Where” and “oh”. Therefore, in this case, as shown in FIG. 8, a mark of * is automatically generated and inserted in that portion and displayed on the liquid crystal display 21. Then, the balls 42 are sequentially moved through the inserted * mark.
[0061]
That is, when the key is pressed at the timing when the ball 42 has moved over the character “Where”, the ball 42 moves over “*” based on the jump distance calculated from the number of characters “Where”. I will do it. Then, when the key 42 is pressed again when the ball 42 reaches the “*”, the next “oh” is calculated based on the jump distance calculated with the number of characters of the mark “*” as one character. The ball 42 moves upward.
[0062]
FIG. 9 is a flowchart showing an operation when performing navigation display for one line on the liquid crystal display 21 in the present embodiment. This flowchart is performed using a display pointer. Since the navigation display using the display pointer is performed collectively in units of one measure, the display pointer remains at the bar mark. Therefore, in the first step S1 after the start of the navigation display process, first a bar mark is read.
[0063]
Next, in step S2, the display pointer is advanced, and in step S3, the data indicated by the current display pointer is read. In step S4, it is determined whether or not the read data is a bar mark. If it is not a bar mark, the process proceeds to step S5 to determine whether or not the read data is a beat mark. If the read data is a beat mark, the process returns to step S2, and if it is not a beat mark, the process proceeds to step S6 to further determine whether the read data is note data.
[0064]
If it is determined in step S6 that the read data is not note data, the data is lyric data. In this case, the process proceeds to step S7, where it is recognized that there is lyric data corresponding to certain note data, and the process returns to step S2. On the other hand, if it is determined that the read data is note data, the process proceeds to step S8 to determine whether or not there is lyrics data corresponding to the note data.
[0065]
At this time, if the corresponding lyric data exists, the process proceeds to step S9, and the lyric is displayed on the liquid crystal display 21. On the other hand, if there is no corresponding lyric data, a mark “*” is automatically inserted in that portion and displayed on the liquid crystal display 21. After the process of step S9 or step S10, the process returns to step S2 to advance the display pointer, and in the next step S3, data indicated by a new display pointer is read. In step S4, it is determined whether or not the read data is a bar mark. If it is a bar mark, navigation display processing for one bar has been completed, and the navigation display process is terminated.
[0066]
Although not shown in FIG. 9, as described in the second embodiment, when the jump distance, height, and speed of the ball 42 are calculated in advance for one bar according to the progress of the display pointer, The jump distance and the like are calculated in consideration of the “*” mark inserted in S10. The step of performing such a calculation enters, for example, at the end of the loop process shown in FIG. 9, that is, before returning to the process of step S2.
[0067]
On the other hand, when the calculation of the jump distance, height, and speed of the ball 42 is sequentially performed according to the performance pointer every time a key is pressed, the step of performing such calculation is the navigation display processing. Is executed in another key pressing process (executed when any key is pressed).
[0068]
As described above, in the present embodiment, when navigating and displaying the ball 42 by moving it over the lyrics 41, a predetermined mark or the like is automatically inserted at a position where there is a note but no lyrics. Since the ball 42 is moved also through the inserted mark or the like, the next key pressing timing can be surely known even at a position where there is a note but no lyrics. Also, it can be easily recognized by a predetermined mark that the key should be pressed but at the same time there is no lyrics to be sung.
[0069]
(Fifth embodiment)
In the second to fourth embodiments, the liquid crystal display 21 is configured to display only one line of navigation of automatic performance data having a length corresponding to four quarter notes. However, in this case, the performer can know only the key pressing timing immediately after. Also, since the navigation display for the next line is switched immediately after the last performance displayed in the navigation display on that one line is executed, the next key pressing timing is known until immediately before the switching, particularly in the display switching part. Can't play, making it difficult to play.
[0070]
Therefore, in the fifth embodiment, as shown in FIG. 10, four lines of navigation related to automatic performance data having a length of four quarter notes are displayed on the liquid crystal display 21 and the display is switched. By devising it, the visibility of the navigation display is improved, and it is easier to perform and sing.
[0071]
In each line of the liquid crystal display 21, lyrics 41 corresponding to the first beat, the second beat,... Are displayed from the left to the right, and the ball 42 bounces on the lyrics 41 each time a key is pressed. Move. When the key is pressed at the last timing of the first line, the ball 42 moves to the beginning of the second line, and then moves to the right again while bouncing on the lyrics 41.
[0072]
Then, when the actual key pressing is executed according to the navigation display of the first key pressing timing on the fourth line, the navigation display on the first line which has already been performed at that time follows the automatic performance data on the fourth line. It is possible to switch to a new navigation display according to the performance data. That is, the navigation display process as shown in FIG. 9 is executed once (for one bar). Note that when automatic performance data is completed in the fourth row, such switching is not performed.
[0073]
Furthermore, when the performance of the fourth line is finished and the key is actually executed at the first key pressing timing of the first line in accordance with the new navigation display of the first line switched as described above, The navigation display on the 2nd to 4th lines that has already been performed is switched to a new navigation display corresponding to the next performance data following the performance data on the 1st line. That is, the navigation display process as shown in FIG. 9 is executed three times (for three bars).
[0074]
Note that when the automatic performance data is completed in the newly switched first row (the fifth row in total), such switching is not performed. In such a case, the 2nd to 4th lines may be switched to blank. Further, when the remaining automatic performance data is less than the 3rd row of the 2nd to 4th rows, a new navigation display may be displayed as much as it exists, and the rest may be left blank.
[0075]
Here, the navigation display on the first line is switched when the key is pressed according to the first key pressing timing on the fourth line. However, the second and subsequent key pressing timings on the fourth line (however, It may be switched when a key is pressed at a time other than the key pressing timing. Alternatively, the navigation display on the first line may be switched when the key is pressed at an arbitrary timing on the second or third line before the fourth line.
[0076]
In the above example, the navigation display of the 2nd to 4th lines is switched when the key is pressed according to the first key pressing timing of the 1st line. However, it may be switched when the key is pressed at the time (except the last key pressing timing).
[0077]
In short, instead of switching to the next navigation display immediately before and after the performance of a certain line, switch to the next navigation display from the already played performance when some performance remains. If it is, what kind of form may be sufficient. However, if the display is switched at a very early timing, it may be difficult to understand how far the performance has been performed, so the above example is more preferable.
[0078]
In the above example, the navigation display on the first line is switched when the key is pressed in accordance with the first key pressing timing on the fourth line. However, the performance data on the fourth line may be all rests. obtain. In this case, since the navigation display on the fourth line is blank, it cannot be determined whether the fourth line is all rests or whether the automatic performance data is completed on the third line. Therefore, in this case, the navigation display of the first line may be switched when the key is pressed at the first timing of the third line.
[0079]
FIG. 9 and FIG. 11 and FIG. 12 shown below are flowcharts for explaining in detail the operation of the electronic musical instrument according to the fifth embodiment. As described above, both automatic performance by key depression and navigation display are performed based on automatic performance data. However, the read pointer on the automatic performance data is managed in a binary manner by the performance pointer and the display pointer. ing. Among these, the navigation display process performed using the display pointer is illustrated in FIG.
[0080]
FIG. 11 is a flowchart showing an operation when sound generation processing based on automatic performance data is performed in accordance with the performance pointer, and is executed when the keyboard scanning circuit 15 detects that any key has been pressed. Is. Here, the jump distance, height, and speed of the ball 42 are calculated in advance according to the progress of the display pointer, and such a calculation step is not included in FIG.
[0081]
In FIG. 11, when any key is pressed, one piece of data indicated by the current performance pointer is read from the automatic performance data stored in the ROM 11 or RAM 12 in step S11. In step S12, it is determined whether or not the read data is bar mark, beat mark or lyric data. If so, the process proceeds to step S13 because this is not note data itself, and the performance pointer is set to the next. The process proceeds to step S11.
[0082]
On the other hand, if the read data is neither a bar mark, a beat mark nor lyric data, the data is note data. In this case, the process proceeds to step S14. In step S14, sound generation processing is performed in accordance with the note data indicated by the current performance pointer. In the next step S15, one jump movement of the ball 42 existing at the current performance pointer position is started. Then, after the navigation display switching determination process is performed in step S16, the performance pointer is advanced in step S17 to end the key pressing process.
[0083]
FIG. 12 is a flowchart showing the operation of the navigation display switching determination process in step S16 shown in FIG. Note that the flowchart shown in FIG. 12 is executed for each key depression after the automatic performance by the key depression is started. On the other hand, in the initial state before the start of performance, when predetermined automatic performance data is selected, the navigation display is already executed for four lines by repeating the flowchart shown in FIG. 9 four times based on the performance data. It is assumed that
[0084]
In FIG. 12, first, in step S21, it is determined whether or not the current performance pointer corresponds to the first navigation display position on the third line from the top of the liquid crystal display 21, and if so, the process proceeds to step S22. It is determined whether or not the automatic performance data on the fourth line is all rests. If the fourth line is not a full rest, the present processing is terminated because the navigation display switching timing is not currently reached, but if the fourth line is a full rest, the process proceeds to step S24.
[0085]
On the other hand, if it is determined in step S21 that the current performance pointer is not at the first position on the third line, the process proceeds to step S23 to determine whether or not the current performance pointer is at the first position on the fourth line. To do. Here, if the first position in the fourth row is hit, the process proceeds to step S24.
[0086]
In step S24, it is determined whether or not the next performance data (the performance data following the performance data on the fourth line) still exists. If there is, the process proceeds to step S25, where the navigation on the first line is performed based on the performance data. Switch the gate display. That is, here, the process of the flowchart shown in FIG. 9 is performed once. In the present example, the jump distance, height, and speed of the ball 42 are executed in the flowchart of FIG. 9 (not shown but before returning to step S2).
[0087]
If it is determined in step S23 that the current performance pointer does not hit the first position on the fourth line, the process jumps to step S26 to determine whether or not it hits the first position on the first line. If it is the first position in the first row, the process proceeds to step S27 to determine whether or not the next performance data still exists. If there is, the process proceeds to step S28, and the navigation display on the second to fourth lines is switched based on the performance data. That is, here, the process of the flowchart shown in FIG. 9 is performed three times.
[0088]
On the other hand, if it is determined in step S26 that the current performance pointer does not hit the first position on the first line, the present processing is terminated because the navigation display switching timing is not currently reached. If it is determined in step S24 or step S27 that the next performance data does not exist, the navigation display switching timing is currently set, but there is no automatic performance data to be played, and the performance advances to the final stage. Therefore, this process is also terminated in this case.
[0089]
As described above, in this embodiment, the navigation display of the key pressing timing having the length of four quarter notes is simultaneously displayed on the liquid crystal display 21 for four lines. Accordingly, it is possible to perform the performance while grasping not only the key pressing timing immediately after the current performance but also the key pressing timing considerably earlier, and the performance can be facilitated.
[0090]
In the present embodiment, when a performance is performed according to a navigation display on a certain line, the navigation display on a line that has already been performed is switched to a new navigation display in advance. For example, the first line is newly displayed when the performance enters the last line that is currently navigated, and the second and subsequent lines are newly displayed when the performance enters the first line from the last line. Yes. Thereby, since the previous navigation display is always performed with a margin, it is possible to make it easier to grasp the key pressing timing and to make it easier to perform.
[0091]
In the fifth embodiment, the navigation display for four quarter notes is displayed for four lines. However, the display is not limited to four lines, and any number of lines may be used as long as there are a plurality of lines. . Also, the amount displayed in one line is not limited to four quarter notes, and a longer or shorter amount may be displayed. As described above, the timing for switching the navigation display is not limited to the key pressing timing at the top of the first line, the top of the third line, and the top of the fourth line.

【The invention's effect】
As described above, the present invention displays lyrics based on the lyrics data in the automatic performance data, and moves and displays the lyrics so as to bounce a predetermined mark in synchronization with the operation of the operator, or Since the lyrics are displayed together with the static guide display of the operation timing, the key press timing guide display and the lyrics can be displayed on the display on the electronic musical instrument at a time. When singing together, it is not necessary to see the guide display and the lyrics alternately by changing the line of sight, and both performance and singing can be performed easily. Also, in the case of the former configuration, it is only necessary to execute the operation operation when the mark that moves while bouncing on the lyrics comes to a predetermined position, and the timing of the mark that moves gradually is observed. This makes it easier for the performer to grasp the timing of operation of the operator. Furthermore, it becomes clear which part of the lyrics should be sung at the time of the operation, and performance and singing can be performed more easily. Also, the jump distance, jump height and jump speed of the mark are calculated according to the length of the lyrics and the set tempo, etc., and the movement of the mark is displayed based on these calculation results. In addition, it is possible to perform guide display of operation element operation in accordance with various types of automatic performance data and various tempos that can be set, and it is possible to realize automatic performance guide display in accordance with the performer's preference.
[0098]
According to another feature of the present invention, in a portion where there is note data in the automatic performance data but there is no lyric data corresponding thereto, a predetermined mark is displayed as a jump vertically on the spot. Even if there is a note in the part but there is no lyrics corresponding to it, the movement of the mark for the guide display of the control operation is displayed without stopping there, and the timing of the next control operation can be known with certainty it can.
[0099]
In addition, if there is note data in the automatic performance data but there is no corresponding lyric data, an arbitrary mark is inserted in that part and the inserted mark is added as a part of the lyrics to display and mark the lyrics. Since there is a note in the automatic performance data but there is no corresponding lyrics, the movement display of the mark for the guide display of the operator operation is performed without stopping there. The timing of the next operator operation can also be surely known.
[0100]
In addition, according to another feature of the present invention, when the operation timing guide is displayed, the operation timing guide is displayed in a plurality of lines, so that more guide information can be displayed at a time than in the past. The guide display can be performed considerably beyond the current performance position. Thereby, the performer can perform the performance while grasping the operation timing considerably ahead, and can easily perform the performance.
[0101]
Further, according to another feature of the present invention, when the operator operation is performed according to the guide display of a certain line, the lyric display of the operated line is switched to the new lyric display. The lyric display of the line where the ending has been completed can be switched in advance to a new lyric display after the current performance, and the guide display can always be performed with a margin. This makes it easier for the performer to grasp the operation timing and makes it easier to perform.
