Next, an example of the navigation information displayed on the LCD 92 by the navigation means in the automatic performance mode will be described. The navigation information is a row of marks corresponding to the key press operation, and this row of marks is composed of a plurality of marks spaced at intervals corresponding to the time of the key press operation. Each mark corresponds to one key press operation (simultaneous operation of a plurality of keys in a performance including a chord or a melody and a chord).
The shape of the mark changes as the music progresses, that is, each time the player presses a key (for example, a circular mark changes to a “+” mark).

FIGS. 4 to 9 are diagrams each showing navigation information of a start portion and an end portion of a performance in one line. First,
In the example of FIG. 4, among the marks included in the navigation information, the first and last marks Ms and Me have different shapes from the other marks Mm. In FIG. 4, each of the marks Ms and Me is a triangle, and is distinguished from the circles of the other marks Mm. In the example of FIG.
s is a triangle and mark Me is a square.
The other marks Mm are distinguished from the circles.

In the example of FIG. 6, among the marks included in the navigation information, the first and last marks Ms and Me have the same shape as the other marks Mm, but have different colors. In this case, the mark Ms and the mark Me
May be the same color or different.
For example, the mark Ms is blue and the mark Me is red. In order to distinguish the marks by color, the LCD 92 can of course be displayed in color.
If the marks Ms and Me are outlined and the other marks Mm are painted black, the player can recognize the difference between the marks even with a monochrome LCD.

In the example of FIG. 7, a mark indicating the start and end of a music piece is included in the navigation information, in addition to the mark corresponding to the musical note. For example, a start line Bs composed of a vertical line such as a bar line is added before the head mark Ms, and an end line Be composed of two lines is added after the last mark Me. Note that the start line Bs and the end line Be are not limited to the vertical line or the two lines, but may be any mark added before the mark Ms or adjacent thereto after the mark Me so that the two can be distinguished.

In the example of FIG. 8, the number of remaining key operations for notifying the end of the navigation information corresponding to the performance data is displayed. As shown in the figure, a number N indicating the number of remaining operations is displayed at the upper right of the column of the mark constituting the navigation information. The number of remaining operations N is decremented by one in accordance with the progress of the performance, that is, each time the keyboard is operated. The display of the number N is not limited to being displayed as a part of the navigation information of the last part of the performance as shown in FIG. 8, but may be displayed at any time of the navigation information from the first part to the last part of the performance. Alternatively, the display may be started when the number of remaining operations N reaches a preset number.

In the example shown in FIG. 9, a display indicating advance of the end of the navigation information is displayed by a progress indicator indicating the progress of the performance. As shown, a bar-shaped display section DI is provided below the navigation information. In the display section DI, the color of an area corresponding to the degree of progress of the performance (the ratio of the performance end to the entire performance data) changes. Since the length of the display section DI corresponds to the length of the entire music piece, if the performance advances to half, the color of the display section DI changes to half of the length. The progress of the performance can be determined by the number of key presses or the actual number of sounds. For chords and note data played simultaneously with the left and right hands, a plurality of key presses are counted as one key press.

FIG. 9A shows a display at the start of a performance.
The display DI is entirely white. On the other hand, FIG. 9B shows a display immediately before the end of the performance (four operations are left).
Most of the length of the display unit DI is changed to, for example, red (black in the figure). With such a display, the player can easily recognize whether the navigator information is that of the start or end of the performance.

Note that the display section DI is not limited to a rod-shaped display section.
It may be displayed in the form of a pie chart, or may be configured such that a point-like object (spot) moves in a direction along a row of marks according to the progress of the performance.

FIG. 10 shows an example in which the navigation information is displayed on the LCD 92 in a plurality of lines. As shown, a blank row BL is provided between the navigation information corresponding to the end of the performance data and the navigation information corresponding to the start of the performance data at the time of repetition. By displaying the navigation information in the state where the blank row BL is provided in this manner, the boundary between music pieces can be clarified.

FIG. 11 shows a display example by the conventional navigation means without a blank line BL. If no blank line BL is provided, it is difficult to distinguish between the navigation information corresponding to the end of the performance and the navigation information corresponding to the start of the next performance.

FIG. 12 is a flowchart of the navigation process of the electronic piano. This process is started when the panel scan circuit 91a detects that the music selection switch 15 has been turned on. In step S1, performance data corresponding to music selection information detected by the panel scan circuit 91a is loaded from the ROM 2 to the RAM 3. Note that each note data constituting the performance data includes a key number, a step time, a gate time, and a velocity. The key number indicates the pitch, the step time indicates the sounding timing, the gate time indicates the sounding duration, and the velocity indicates the key pressing speed, that is, the key pressing strength. When the performance data is loaded into the RAM 3, the contents of the register storing the read address of the performance data are reset. In step S2, the image data of the mark constituting the navigation information is loaded from the ROM 2 to the RAM 3.

In step S3, a step time and a gate time, ie, timing information relating to a predetermined amount of note data (for example, one bar (hereinafter referred to as "predetermined amount")) are read from the performance data in accordance with the address of the register. In step S4, a value indicating the interval between marks constituting the navigation information, that is, the key pressing interval is determined based on the step time and the gate time, and in step S5, the schedule is determined based on the image data and the interval of the mark. Generate navigation information corresponding to the amount of note data.

In step S6, it is determined whether or not the predetermined amount of note data is the first part of the performance data. If this determination is affirmative, the process proceeds to step S7, where the image data of the mark corresponding to the note data of the first predetermined amount of the navigation information is changed. That is, the image data of the original mark is replaced with image data of a mark having a different shape. If step S6 is negative, the process proceeds to step S8, and it is determined whether or not the predetermined amount of note data is the last part of the performance data. If this judgment is affirmative, step S9
To change the image data of the mark corresponding to the last note data. That is, the image data of the original mark is replaced with image data of a mark having a different shape. Note that the shapes of the marks after conversion in step S7 and step S9 may be the same or may be different from each other.

In step S10, image data of navigation information is supplied to a display driver for energizing the LCD 92. The display driver activates the LCD 92 according to the supplied image data to display navigation information.

In step S11, the key scan circuit 7a
The presence / absence of key depression is determined based on the detection result. If a key press is detected, a sound generation process is performed in step S12. Specifically, note data to be generated by one key press is stored in RA
It is read from M3 and set to the channel of the sound source device 4. If a key press has not been detected for a predetermined time, step S17 is performed.
Proceed to.

In step S13, the navigation information mark corresponding to the note data provided in step S12 is changed to another shape ("+") indicating that the music has been played.

In step S14, the read address is advanced by one to correspond to the next key press. In step S15, it is determined whether or not the performance has been completed up to the end of the predetermined amount of note data based on the read address. If the determination is affirmative, the process proceeds to step S16. If step S15 is negative, the process proceeds to step S11.

In step S16, it is determined whether or not the performance has been completed up to the end of the performance data. If the determination is affirmative, the process proceeds to step S17. If the performance has not been completed to the end, step S16 is negative and the process proceeds to step S3. In step S17, it is determined whether or not the stop switch 16 for terminating the performance has been pressed. If the determination is negative, the process proceeds to step S18 to repeat the performance, the read address is reset, and the process proceeds to step S3. If step S7 is positive, the process ends.

In steps S7 and S9, the shapes of the first mark of the first bar and the last mark of the last bar are changed. However, when the colors of these marks are changed as shown in FIG. In step S7 or step S9, color information associated with the image data of the mark may be changed. Also, when the start line Bs and the end line Be are added as shown in FIG. 7 before the first mark and after the last mark, respectively, the start line Bs and the end line Be are represented in steps S7 and S9. Therefore, image data stored in advance may be added.

FIG. 13 is a flow chart of a process for displaying the number N of remaining key operations as the means for displaying the end time of the guidance display of the key depression timing, as shown in step S6.
This is executed instead of S15. In step S20, the remaining number of operations N is calculated by subtracting the actual number of operations n from the initial value NI of the number of operations. In step S21, the image data of the number representing the number of remaining operations N is stored in step S21.
5. Synthesize with the image data generated in step 5. Step S2
In steps S2 to S25, the same processing as in steps S10 to S13 is performed.

In step S26, the number of operations n is incremented. In step S27, the read address is advanced by one to correspond to the next key press. In step S28, it is determined whether or not the performance has been completed up to the end of the bar based on the read address.
Proceed to. If step S28 is negative, the process proceeds to step S20.

FIG. 14 is a flowchart of a process for displaying a display section DI, which is a performance progress indicator, as an end time notice display means of a key press timing guide display, which is executed in place of steps S6 to S15. . In step S30, the number of remaining operations N is calculated as in step S20. In step S31, the number N of remaining operations is divided by the initial value NI of the number of operations to obtain a performance end ratio R.
Calculate (%). In step S32, of the image data representing the display section DI, the color information corresponding to the length corresponding to the ratio R is changed. For monochrome display, the digital value of the image data is inverted instead of changing the color information. In step S33, the image data of the display unit DI is combined with the image data generated in step S5. In steps S34 to S37, the step S
The same processing as in steps S10 to S13 is performed. Steps S38 to S40 are processed in the same manner as steps S26 to S28.

FIG. 15 is a flowchart of a process for providing a blank line BL for indicating the repetition of music when displaying navigator information in a plurality of lines.
This is executed instead of S9. In step S50, it is determined whether or not the musical data is the first predetermined amount of the musical performance data.
If this determination is affirmative, the process proceeds to step S51, where data for displaying the blank row BL is output to the display driver, and a blank is displayed. Subsequently, in step S52, the image data generated in step S5 is output to the display driver to display the nigator information. Thus, a blank line B between the last part and the first part of the song
Navigator information having L is displayed on LCD 92.
If step S50 is negative, step S51 is skipped and the process proceeds to step S52, in which navigation information is displayed without providing a blank line BL.

FIG. 1 is a block diagram showing the main functions of the CPU 1 for displaying the navigation information. In the figure, the performance data storage unit 23 stores key press timing information. The navigation information creating unit 24 creates image data of navigation information including marks having intervals determined based on the timing information. The navigation information is created for a predetermined number of note data. The created image data is input to the display driver 25 via the switching unit 27, and the display driver 25 activates the LCD 92 according to the image data to display the navigation information.

The determining section 26 determines whether the predetermined amount of note data is the first or last part of the performance data. This determination is made from the additional information of the note data. Then, if it is the first or last part, the switching unit 27 is switched, and the image data created by the navigation information creating unit 24 is input to the data correcting unit 28.

On the other hand, the remaining performance detector 29 calculates the number of remaining operations or the performance end ratio based on the number of key presses detected by the key scan circuit 7a. The calculated number of remaining operations and the performance end ratio are input to the data correction unit 28.

The data correction unit 28 converts the shape or color of the scheduled portion of the input image data,
Based on the number of remaining operations or the performance end ratio, numbers representing these and image data of the display unit DI are generated and added to the image data input from the navigation information creating unit 24. The image data processed by the data correction unit 28 is input to the display driver 25.

Although the present invention has been described with reference to the preferred embodiment, the following modifications are possible.
For example, a blank line BL is displayed in the navigation information display of a plurality of lines so as to recognize the repetition of the music. However, in the display of each line, the navigation information of the first part of the next music is displayed. There will be a time delay before. That is, the timer for setting the scheduled time is started when all the marks of the last navigation information of the previous song are converted to "+", and when the timer expires, the first portion of the next song is navigated. Display information. Until the timer is started and the time is up, automatic performance is not started even if the player presses a key.

As a further modification, a counter for counting the number of key presses is activated when all the marks of the last navigation information of the previous song have been converted to "+", and the player has pressed the key a predetermined number of times. Sometimes, the display of the navigation information of the next song can be started.
