2. Description of the Related Art In a keyboard instrument such as a piano or an electronic keyboard, a performance is performed by successively pressing the keys to be pressed. As a method (performance guide method) of guiding the performance assuming the performer (user), an object is scrolled for each key (pitch of a musical tone) to indicate at least the key depression timing at which the key should be depressed. The method of displaying is widely adopted.

In the performance guide method adopting the scroll display method, an object scroll-displayed toward an image showing a key (pitch) is made to reach a predetermined position or the deletion thereof is started. , Denote the key depression timing of the key to which it is assigned (teaching)
To do. In this way, since the key depression timing is expressed for each key, it is possible to easily grasp the correspondence relationship between the key to be depressed and the key depression timing. In addition, since the key to be pressed is known before it is time to press the key, the performer can play with more margin.

[0004]

In the conventional performance guide method, basically, only the key depression timing is taught for each key through the scroll display of the object. However, even if the keys to be pressed are indicated in advance by scrolling the objects, performers who are unskilled in playing technique
The reality is that we do not know how to press the key corresponding to that object.

Therefore, the performance guide may teach the performer not only the key to be pressed and the timing of the key pressing but also how to press the key to be pressed. Considered to be important. It can be said that a player who is inexperienced in playing technique does not have enough time to perform a performance, and therefore it is necessary to give the teaching in a more understandable form.

An object of the present invention is to provide a technique for teaching a player how to press a key in addition to the key to be pressed and the key pressing timing.

102 and a RAM 1 used by the CPU 101 for work
03, a tone generator LSI 104 for generating waveform data of a musical sound to be generated according to an instruction from the CPU 101, and its LS.
A sound system 105 that outputs the waveform data generated by the I104 as a sound, a switch (SW) group 106 having various switches, a keyboard 107 that is a target of a performance operation, and a DP (that stores image data output from the CPU 101). Dual port) -RAM 108, VDP (video digital processor) 109 for generating image data for display using image data stored in the RAM 108, and image data generated by the VDP 109 for a television such as an NTSC signal. And a converter 110 for converting into a signal for John (hereinafter, television). As a result, the performance guide device according to the present embodiment is realized as a device that guides a performance through an image displayed on the television connected via converter 110.

The switch group 106 is composed of, for example, operators such as various switches and buttons, and a detection circuit for detecting an operation on those operators. The operators include a start / stop switch for instructing the start or end of the performance guide, a ten-key pad, and a song switch for selecting a music piece targeted by the performance guide. The musical piece to be the target of the performance guide is designed by operating the song switch and then designating the number assigned to the desired musical piece (the musical piece number) with the ten keys.

The VDP 109 is, for example, a built-in RAM
The data indicating the position where the image data to be arranged received from the CPU 101 is stored in the 109a, and the DP-RAM 1
Image data for display is generated by arranging the image data stored in 08 in accordance with the data stored in the RAM 109 so as to be superimposed and arranged in a predetermined order.

The operation of the above configuration will be described. When a power source (not shown) is turned on, the CPU 101 turns the RO
The control of the entire musical instrument is started by reading and executing the program stored in M102. After that, R
Switch group 106 while using AM103 for work
Each unit is controlled in accordance with a signal indicating the state of the operator received from the keyboard 107 or the keyboard 107. The switch group 10
The detection circuit constituting 6 detects a change in the state of each switch (including the presence / absence of operation) from, for example, a voltage value that changes according to the state. The keyboard 107 (the detection circuit constituting the keyboard) detects the state of each key, for example, by scanning it.

When the CPU 101 receives a signal indicating the state of each key from the keyboard 107, the CPU 101 identifies the key whose state has changed by comparing it with the previously detected state.
When such a key can be specified, a control command to be sent to the tone generator LSI 104 is generated according to the specified key and a change in the state of the key, and the generated control command is sent.

On the other hand, the CPU 101 has a switch group 106.
In accordance with a change in the state of each switch that makes up the switch, a process for realizing the function assigned to the switch whose state has changed is performed. By performing the processing, various settings including the setting of the musical piece to be the performance guide, the performance guide, and the like are realized. The performance guide is started in response to the operation of the start / stop switch, and is performed until it is ended or the switch is operated again.

FIG. 2 is a diagram for explaining the performance guide method according to this embodiment. 5 shows an example of contents displayed on a television by the VDP 109 generating image data. Here, the performance guide method will be specifically described with reference to FIG. In FIG. 2, an image (hereinafter, referred to as a scale image) 201 in which pitch names represented by “do” to “shi” are arranged in pitch order in frames arranged on a straight line is a key to be pressed on the keyboard 107. Is displayed to indicate. The key to be pressed (the pitch of the key) and the key pressing timing to press the key include the position of the pitch name corresponding to the key to be pressed among the pitch names arranged in the scale image 201. Image 201
A star-shaped object on a line in a direction orthogonal to the longitudinal direction (hereinafter, referred to as a note object because it corresponds to a note on a musical score. It corresponds to the "first object" described in the claims. ) 202 and scrolls in the direction of the arrow in FIG. 2 toward the image 201 to teach.

In the present embodiment, the longitudinal direction of the scale image 201 coincides with the X-axis direction, and the orthogonal direction thereof coincides with the Y-axis direction. As a result, X, which is the position on the X axis,
The coordinate value indicates the pitch of the key to be pressed using the note object 202. Y which is the position on the Y-axis
The coordinate value or the interval thereof indicates the time of performance. The direction in which the pitch of the pitch name shown in the scale image 201 is high is the positive direction on the X axis, and the direction away from it is the positive direction on the Y axis.

Scale image 201 and note object 202
As shown in Fig. 2, between "parent", "person", and "middle"
An object 203 having a “drug” or “small” symbol inside is arranged. "Parent""Person""Medium"
The symbols “medicine” and “small” represent the thumb, the index finger, the middle finger, the ring finger, and the little finger, respectively. An object that has any of those symbols (hereinafter,
A finger object) 203 is arranged at the X coordinate value corresponding to the pitch assigned to the key in order to teach the key to be pressed using the finger it represents. That is, the key is pressed above the note name (the opposite direction of the arrow in the figure = the positive direction on the Y axis) corresponding to the key to be pressed (the pitch of the musical sound to be generated) in the scale image 201. A finger object 203 to be used as a key is arranged. Thereby,
The correspondence between the key to be depressed and the finger to be used for the key depression can be easily recognized.

The correspondence is shown by securing a space for displaying the finger object 203 in each frame of the scale image 201 and displaying the finger object 203 in the secured space as needed. Is also good. It may be indicated by switching the display color of the frame or the inside thereof. In this way, various methods can be used to show the correspondence. Since the scale image 201 is fixedly displayed, it may be fixedly arranged on a dedicated display device by printing or the like.

By arranging the finger object 203 between the scale image 201 and the note object 202, the note object 202 represents the finger to be used for pressing the key to which the pitch indicated by the X coordinate value is assigned. The shape is such that it scrolls toward the finger object 203. As a result, for the performer (user of the electronic keyboard instrument), the finger or key to be pressed (the musical tone to be pronounced) should be emphasized while the finger to be used for key pressing is further emphasized before the key pressing timing comes. Pitch) is taught.

By emphasizing the teaching of the finger to be used for key depression, the player is more strongly aware that he / she should move his / her finger so that he / she can press the taught key. . As a result of making such consciousness work harder,
Compared with the case of simply teaching the finger to be used for key depression or the key to be depressed in advance, the performer can move the fingers more smoothly so that the taught key can be depressed with the finger. . As a result, the player is guided so that the performance can be performed more easily.

As shown in FIG. 2, a plurality of finger objects 203 are always displayed. This means that if there is a key to be pressed after the next key depression, the meaning of teaching the finger to be used to press that key at an earlier point in time, other than the finger to be used for the next key depression, is included. This is to teach the key to keep the finger in position.

As the number of finger positions designated at one time increases,
The range of positions where you can put your hand is narrowed. Therefore, when the positions of a plurality of fingers are designated (teached) at a time, the position to place the hand is substantially designated (taught), and the fingers to be used for subsequent key depression are taught at an earlier point in time. become. By designating (teaching) the positions of the hands and fingers, it is necessary to move the fingers in an appropriate shape in order to press the key. As a result, the performer not only can play with more leeway, but also can learn how to carry fingers more appropriately.

As is well known, the hand must be moved as needed. In the present embodiment, in order to teach the necessity of the movement, a frame object 204 having a width of a range of five note names on the X-axis, and an object (arrow in which the arrow indicating the moving direction is arranged in the frame ( Hereinafter, 205 or 206 will be arranged), and they will be scroll-displayed together with the note object 202.

The display position of the frame object 204 on the X axis is changed according to the position where the hand should be placed. As a result, through scroll display of the frame object 204, the timing to move the hand, the direction to move the hand, and the amount of movement (position to place the hand) are taught.

In FIG. 2, the frame object 204 closest to the scale image 201 and the next frame object 204 next to it.
With, the display position is shifted to the right by one note name (it corresponds to the side where the position on the X-axis is large. Hereinafter, unless otherwise specified, the left and right will be expressed by focusing on the position on the X-axis). The shift indicates the amount of hand movement.

The lower side (the side on which the position on the Y-axis is small is a constituent of the frame object 204 that is the second closest to the scale image 201.
Hereinafter, unless otherwise specified, the arrow object 205 arranged so as to overlap the line above and below will be described by shifting the display position of the frame object 204 to the right. It is displayed in order to visually teach the direction to be made by another method. The same applies to the arrow object 206. In the present embodiment, by using such a plurality of objects, it is easier to understand how to move the hand.

A frame object 20 for teaching the movement of the hand
4, that is, the note object 202 located at the lower end of the frame object 204 whose display position on the X axis is different from that of the lower frame object 204, as shown in FIG. A number (finger number) 207 assigned to the power finger is arranged. "4" in Fig. 2 is
Pointing to the ring finger. Hereinafter, the displayed finger number 207 will be collectively referred to as a number object.

As the hand is moved, the correspondence between the key and the finger to be placed there changes up to that point. The display positions of all the finger objects 203 are often changed. For this reason, the finger to be used for key depression after the movement of the hand becomes difficult to understand, and the performer is likely to be confused.
However, when the number object 207 is arranged in the vicinity of the note object 202, the player can know in advance the finger to be used for the key depression after the movement of the hand.
As your hands move, you will be able to avoid confusing things. This is why the number object 207 is displayed.

In the present embodiment, in addition to the above-mentioned various objects 201 to 207, a symbol (any one of "do" to "shi") indicating the note name corresponding to the note object 202. Collectively referred to as object) 2
08 is displayed at the same position on the Y axis as the object 202. The position on the X axis is a predetermined position on the left side of the position. The scale object (symbol) 208 displayed at such a position is scrolled together with the note object 202. In this way, the player can recognize the key to be pressed from the displayed scale object 208.

In order to realize the performance guide by scroll display as described above, the following data is prepared in this embodiment. FIG. 3 is a diagram for explaining the structure of performance data. The performance data defines the types of objects to be displayed other than the scale image 201, their display positions, etc., based on the performance content of the music. As a result, the scroll display for performing the performance guide is performed by referring to the performance data. The performance data is prepared in the ROM 102 for a plurality of songs, and the selection is made by operating the song switch and then designating the song number assigned to the desired song using the ten keys, as described above. It has become.

The performance data is, as shown in FIG. 3, hand position data representing the position of the hand, finger position data representing the position of the finger, note data representing the musical sound to be generated (key to be pressed), and The rest data, which represents the time when a musical sound should not be produced, is formed by arranging necessary data in the processing order.

The hand position data is divided into those at the beginning of the performance data and those not. The one at the top is composed of a frame code indicating the type of the frame 204 and XY coordinate data designating the display position of the frame 204 indicated by it, and the other is the type of the arrow object in addition to them. The arrow code shown is added. There is no arrow code at the beginning because the position where the hand should be placed at the beginning of the performance does not have to be moved from another position. In order to teach the position where the hand should be placed at the start of the performance, the head of the performance data is set to the hand position data.

The finger position data is for designating (including changing here) the correspondence between the finger object 203 and the key to be pressed with the finger indicated by it (the pitch name in the scale image 201). . Finger change code indicating the type of finger object 203 and finger object 203 indicated by the code
And X coordinate data that specifies the display position of the. There is no Y coordinate data because the finger object 203
Is for not scrolling. When there are a plurality of finger objects 203 for which the correspondence is changed, the finger position data is continuous for that number.

The note data is basically composed of pitch data indicating the pitch of a musical tone to be sounded, and note length data indicating the time during which the musical tone is continuously sounded. If the hand position data exists immediately before that, a finger number code indicating the type of the number object 207 to be displayed is added in order to teach the finger to be used for key depression after the hand is moved. The rest data is composed of note length data indicating a time during which no musical sound is produced. The note data and the rest data do not have data indicating the start timing of musical tone generation or the start timing of the period during which the musical tone is not generated because the note length data of the note data can specify the timing.

FIG. 4 is a diagram for explaining the image data stored in the image data area secured in the ROM 102. The image data area is, as shown in FIG.
It is divided into a surface area and a surface B area. Image data for displaying various finger objects 203 and image data to be fixedly displayed (denoted as “fixed data” in the drawing) are stored in the A-side area. The latter image data includes data for displaying the scale image 201 and data for displaying a line extending along the arrow direction in FIG.

In the other side B area, various image data for displaying the note object 202, various scale objects 208, various number objects 207, arrow objects 205 and 206, and various frames 204 are stored. As described above, the VDP 109 shown in FIG.
Is adapted to generate image data for one screen by arranging the image data stored in the DP-RAM 108 according to the data stored in the RAM 109 installed inside in such a manner that they are superposed in a predetermined order. There is. Therefore, the XY coordinate data in the performance data shown in FIG.
Each of them has a value represented by using a predetermined reference point as a reference, and the VDP 109 is designed so that the CPU 101 indicates a range to be a target of image data generation. Figure 4
The CPU 101 of the various image data shown in FIG.
02 and stores it in the DP-RAM 108.

The VDP 109 generates image data for display by using the image data of the object existing in the designated range and outputs it to the converter 110. As a result, a signal for displaying an image as shown in FIG. 2 is output from the converter 110 to the television, and the signal is displayed on the television. The scrolling of the note object 202 and the like is realized by updating the instructed range. Hereinafter, for convenience, a portion for instructing a range and generating image data for display will be referred to as an extraction screen, and a screen actually displayed on the television will be referred to as a display screen.

FIG. 5 is a diagram for explaining the data stored in the display control area secured in the RAM 103 shown in FIG. The display control area is an area reserved by the CPU 101 for storing control data necessary for realizing the performance guide described with reference to FIG.

As shown in FIG. 5, a note area, a scale area, a finger number area, a frame area, and an arrow area are secured in the display control area. In these areas, note object 202, scale object 208, number object 207, frame object 204, and arrow object 205, or 207, respectively.
The display control data of is stored in object units.

All the data are handled as two-dimensional array variables. Of the two brackets shown side by side in the figure,
Numerical values defined in parentheses on the left side (on the notation side closer to the variable name; hereinafter referred to from that viewpoint) are for designating the object targeted by the display control data.
The smaller the numerical value of the object designated by the numerical value, the smaller the Y coordinate value set in the performance data that is displayed at earlier timing. The range of numerical values that can be defined in the other parenthesis is 0 to 2. Value (data) assigned to the element specified by the numerical value
Is a code that indicates the type of object with the numerical value "0",
The numerical value "1" is the X coordinate value, and the numerical value "2" is the Y coordinate value. The display control data of the object is constituted by them. Hereinafter, the name of the area will be used as the array variable name prepared for each area.
Thereby, for example, in the note area, the array variable name corresponding to it is described as "note".

"Display start address Xw" and "display start address Yw" in FIG. 5 are an X coordinate value and a Y coordinate value, respectively, which indicate the start position of the extraction screen. These values are updated at any time as the performance progresses, and VDP1
09 indicates the range to be the target of image data generation with these values. The contents of the extraction screen generated by the VDP 109 change as the values for designating the range are updated. As a result, scrolling in the arrow direction in FIG. 2 is realized. Since scroll display can be performed by updating these values, all the data to be stored is stored at once in each of the note area, scale area, finger number area, frame area, and arrow area. . Hereinafter, the “display start address Xw” and the “display start address Yw” are abbreviated as “address Xw” and “address Yw”, respectively.

The finger object 203 is an object which is not scrolled and whose display position on the X axis must be changed each time the correspondence between the finger and the key changes. The display control data is handled as a two-dimensional array variable like other objects. In the figure, a "finger" with two parentheses arranged side by side indicates the variable name. Of the two parentheses, the numerical values 1 to 5 written in the parentheses on the left side are for designating the finger object 203 targeted by the display control data. Similarly to the finger number, for example, "1" designates the finger object 203 of the thumb and "5".
Specifies the finger object 203 of the little finger. The numerical value that can be defined in the other parenthesis is in the range of 0-2. The value (data) assigned to the element specified by the numerical value is
"0" indicates the finger number code, "1" indicates the X coordinate value for displaying the target finger object 203, and "2" indicates the Y coordinate.
It is a coordinate value. The display control data of the finger object 203 is composed of them.

FIG. 5 shows only the data whose contents change depending on the performance data or which is updated at any time. In addition to such data, the scale image 201
Display control data such as is stored in the display control area. In the present embodiment, the object whose actual display position on the Y-axis is not changed, that is, the scale image 201 and each finger object 203, is treated as a screen different from the above-mentioned extraction screen. If the other screen is called a background (BG) screen, the BG screen is as shown in FIG. The display screen is generated by superimposing the extraction screen on the BG screen.

When the start / stop switch is operated, the CPU 101 reads the performance data of the music set as the target at that time from the ROM 102, and a note area, a scale area, a finger number area secured in the display control area, Display control data is stored in each of the frame area and the arrow area. The display control data is sent to the VDP 109 and stored in the RAM 109a. After that, the display control data and the addresses Xw and Yw of each finger object 203 are updated at any time with the passage of time, the updated data is sent to the VDP 109, and the update is reflected in the data stored in the RAM 109a. .
As a result, the performance guide by scroll display described with reference to FIG. 2 is realized. The RAM 109a has a structure similar to that of the display control area shown in FIG. 5, and stores display control data.

Next, the CPU 101 which realizes a performance guide by displaying various objects as described above,
The operation of the VDP 109 will be described in detail with reference to various flowcharts shown in FIGS. Figure 7
3 is an operation flowchart of overall processing executed by the CPU 101. First, the overall process will be described in detail with reference to FIG. 7. The entire process is the ROM 102
It is realized by executing the program stored in.

In step 701, which is first executed after the power is turned on, initialization is performed to set the musical instrument to a predetermined state. By the initialization, the sound source LSI 104 is initialized to a predetermined state, and D
Various image data shown in FIG. 4 is stored in the P-RAM 108. Then, the process proceeds to step 702.

In step 702, a guide display process for guiding the performance of the music desired by the user is executed. In a succeeding step 703, keyboard processing for executing the operation on the keyboard 107 by the user is executed. In step 704, which moves to the next step, other processing for responding to a user's operation on the switch group 106 is executed. After that, the process returns to step 702.
Thereby, while the power is on, steps 702-
By repeatedly executing the processing loop formed by 704, the user operates the switch group 106 and the keyboard 107.

Next, the subroutine processing executed in the above overall processing will be described. FIG. 8 shows the above step 70.
It is a flowchart of the guide display process performed as 2. In the subroutine processing executed in the overall processing, first, the guide display processing will be described in detail with reference to FIG.

First, in step 801, an initial setting process corresponding to the operation of the start / stop switch is executed. In the next step 802, a timer process for realizing scrolling of various objects is executed as time passes. After that, a series of processing is ended.

FIG. 9 is a flowchart of the keyboard processing executed as step 703 in the overall processing shown in FIG. Next, the keyboard processing will be described in detail with reference to FIG. First, in step 901, the detection circuit of the keyboard 107 is instructed to perform scanning, and the scanning result is received. In the following step 902, the scanning result is compared with that received last time to determine the presence / absence of a key whose state has changed in the keyboard 107 and the content of the change. If there is no change in the state of each key on the keyboard 107, that effect is determined, and the series of processing ends here. If there is a change due to a key press (ON) in each key, that effect is determined, and note-on event data for instructing the pronunciation of the musical tone of the pitch assigned to the key that detected the change is output. Created, and the created data is the sound source LSI 104
(Steps 903 and 904), the series of processing is terminated. If there is a change due to key release (off) in each key, that effect is determined, and note-off event data for instructing the mute of the musical tone of the pitch assigned to the key that detected the change is recorded. Created and sent the created data to the sound source LSI 104 (steps 905, 90
4) After that, a series of processing is ended.

In the keyboard processing, the above-mentioned processing is executed. As a result, when the user operates the keyboard 107, a command is generated according to the operated key and the content of the operation, and is sent to the tone generator LSI 104. as a result,
A musical sound is emitted in response to an operation on the keyboard 107.

The subroutine processing executed in the guide display processing shown in FIG. 8 will be described below. Figure 10
Is a flowchart of the initial setting process executed as step 801 in the guide display process. At the beginning,
The initial setting process will be described in detail with reference to FIG. As described above, the initial setting process starts / starts.
This is processing executed in response to a user's instruction to operate the stop switch, that is, to start or end the performance guide. The display control data is stored in the five areas secured in the display control area shown in FIG. 5 by executing this initial setting process.

First, in step 1001, start /
It is determined whether the stop switch is turned on. When the switch is operated (turned on) by the user, the determination is yes and the process moves to step 1002 to invert the value of the variable STF for performance guide management, that is, to 1 if the value up to that point is 0, If is 1, it is overwritten with 0, then step 1
Move to 003. If not, the determination is no, and the series of processes ends here.

In step 1003, it is determined whether or not the value of the variable STF is 1. When the value 1 indicating the situation of performing the performance guide is assigned to the variable STF, the determination is YE.
The process proceeds to S and proceeds to step 1006. Otherwise, the determination is no, and in step 1004 a command for instructing the mute of all musical tones is generated and sent to the tone generator LSI 104, and in step 1005 VD
After instructing P109 to end the generation of the image data, that is, to erase the display, the series of processes is ended.

On the other hand, in step 1006, an initial screen generation process for displaying a display screen (initial screen) to be displayed at the start of the performance guide is executed. Continued Step 10
At 07, a value indicating the start address (the data located at the beginning) is assigned to the variable AD1 for managing the data read out from the performance data. After that, the process proceeds to step 1008.

In step 1008, it is determined whether or not the data designated by the value of the variable AD1 (denoted as "MEM [AD1]" in the figure) is note length data. If the data is not note length data, the determination is no, after incrementing the value of the variable AD1 in step 1009, the process returns to step 1008. Otherwise, the determination is Y
After ES, the note length data is assigned to the variable t in step 1010, and the series of processes is terminated.

By repeatedly executing the processing loop formed in steps 1008 and 1009 until the determination in step 1008 is YES, the variable t is the note at the beginning of the note length data existing in the performance data. Long data is substituted. The note length data is used to manage the progress of the performance guide.

11 to 13 show the above step 1006.
8 is a flowchart of an initial screen generation process executed as. Next, the generation process will be described in detail with reference to FIGS. 11 to 13. The generation process is executed to display the initial screen at the start of the performance guide, as described above.

First, in step 1101, a BG screen display process for displaying a BG screen as shown in FIG. 6 is executed. In the following step 1102, the variable AD2 is set to
Substitute a value indicating the start address of performance data. In step 1103 to be transferred next, variables n1 to n5 prepared for storing the display control data of the object for each area secured in the display control area (see FIG. 5),
Substitute 0 for M respectively. After that, the process proceeds to step 1104.

The variables n1 to n5 are used to specify the elements of the array variables prepared for each area of notes, scales, finger numbers, frames, and arrows. More specifically, it is used to specify an object in parentheses on the left side. The variable M is used to manage the display position on the Y axis of the object to be scrolled by updating the address Yw. After step 1104, a process for storing the display control data in the display control area is performed while updating the values of various variables including the variable AD2 as needed.

First, at step 1104, it is determined whether or not the performance data (see FIG. 3) designated by the value of the variable AD2 (indicated as "MEM [AD2]" in the figure) is a frame code. If the data is not the frame code, the determination is no and the process moves to step 1112.
Otherwise, the determination is yes and step 1
Move to 105.

At step 1105, the value of the variable n4 is incremented. In the following step 1106, the frame code is substituted into the variable n4 of the array variable "frame" for the frame area and the frame [n4] [0] which is the element designated by "0" (see FIG. 5). After that, in step 1107, the frames [n4] [0] are transferred to the VDP 109 and the RAM 109 is transferred.
The value is stored in a and the value of the variable AD2 is incremented in step 1108, and then the process proceeds to step 1109.

In step 1109, it is determined whether or not the data designated by the value of the variable AD2 exists. If there is data to be processed among the performance data, there is data specified by that value, so the determination is NO and the process returns to step 1104. Thereby, all the data to be processed is processed. On the other hand, otherwise, the determination is yes and step 1110.
Substitute the initial values into the addresses Xw and Yw in step 1111 and transfer them to the VDP 109 in step 1111 to R
After storing the data in the AM 109a, the series of processes ends.

By transferring the addresses Xw and Yw to the VDP 109, the display control data necessary for generating the image data (display screen) is stored in the RAM 109a. Thereby, the VDP 109 starts its generation. In step 1112, where the determination in step 1104 is NO and the process shifts, it is determined whether the data designated by the value of the variable AD2 is an arrow code. If the data is the arrow code, the determination is YES, the value of the variable n5 is incremented in step 1113, and the arrow code is changed to the variable n5 of the array variable “arrow” for the arrow area and “ After substituting it into the arrow [n5] [0] that is the element designated by "0", the process proceeds to step 1107, and the arrow [n5] [0] is set to VDP10.
Transfer to 9. Otherwise, the determination is no and the process moves to step 1115 of FIG.

At step 1115, it is determined whether the data designated by the value of the variable AD2 is pitch data. If the data is not pitch data, the determination is no and the process moves to step 1129 in FIG. Otherwise, the determination is yes and the process moves to step 1116.

At step 1116, the value of the variable n1 is incremented. In the following step 1117, the variable n
Increment the value of 2. At the step 1118 to be transferred next, the variable n1 of the array variable "note" for the note area and the note [n which is the element designated by "0"
1] Substitute a note code for [0]. When the substitution is performed, the process proceeds to step 1119, and a chord indicating the pitch name corresponding to the pitch indicated by the pitch data is generated as a scale code. Then, the process proceeds to step 1120.

At step 1120, the generated scale code is substituted into the variable n2 of the array variable "scale" for the scale area and the scale [n2] [0] which is the element designated by "0". In the next step 1121, the X coordinate value corresponding to the pitch indicated by the pitch data is calculated, and in the next step 1122, the X coordinate value is calculated by the variables n1 and “1” of the array variable “note”. Note [n that is the specified element
1] Substitute for [1]. In step 1123, which is performed after the substitution, in the variable n2 of the array variable “scale” and the scale [n2] [1] that is the element designated by “1”,
As the display position of the scale object 208 on the X axis, an X coordinate value fixedly determined in advance (hereinafter, referred to as a fixed X coordinate value) is substituted. Then, the process proceeds to step 1124.

In step 1124, the value of the variable M is used to calculate the Y coordinate value. The Y coordinate values are assigned to the notes [n1] [2] and the notes [n2] [2] as the display positions on the Y axis of the note object 202 and the note object 208, respectively (steps 1125 and 1126). When the substitution is performed, the notes [n1] [0 to 2] and the scale [n
2] [0 to 2] are transferred to the VDP 109 (steps 1127 and 1128), and then step 11 in FIG.
Move to 08.

In this way, if the data designated by the value of the variable AD2 is pitch data, the note object 2
02, while the positions of the scale object 208 on the Y-axis are made to coincide with each other, the display control data for them are both generated and stored in the display control area.

In step 1129 of FIG. 13 in which the determination in step 1115 is NO, the variable AD2 is set.
It is determined whether the data specified by the value of is the note length data. If the data is not note length data, the determination is no and the process moves to step 1131. Otherwise, the determination is yes, after incrementing the value of variable M in step 1130, then step 1 in FIG.
Move to 107.

At step 1131, it is determined whether the data designated by the value of the variable AD2 is a finger number code. If the data is not the finger number code, the determination is no and the process moves to step 1138. Otherwise, the determination is yes and the process moves to step 1132.

At step 1132, the value of the variable n3 is incremented. Next, the process proceeds to step 1133, and the finger number code is set to the variable n3 of the array variable "finger number" for the finger number area and the finger number [n3] [0] which is the element designated by "0". To. In the next step 1134, the X coordinate value is calculated using the X coordinate value corresponding to the pitch indicated by the pitch data in the note data having the finger number code, and in the next step 1135, the X coordinate value is calculated. The X coordinate value is assigned to the finger number [n3] [1].
When the substitution is performed, the process proceeds to step 1136 to configure the finger number [n3] [2] as the display control data of the note object 202 or the scale object 208 generated by the pitch data in the note data. The Y coordinate value (calculated using the value obtained by decrementing the value of the variable M) is substituted. After that, in step 1137, after the finger numbers [n3] [0-2] are transferred to the VDP 109,
1 to step 1107. The X coordinate value is calculated using the X coordinate value corresponding to the pitch indicated by the pitch data in the note data, in order to display the finger number object 208 near the note object 202 (see FIG. 2). .

On the other hand, in step 1138, the variable AD2
It is determined whether the data designated by the value of is the X coordinate data (value). If the data is not X coordinate data, the determination is no and the process moves to step 1145. Otherwise, the determination is yes and step 1139.
Move to.

As shown in FIG. 3, the X coordinate data is arranged after the frame code, the arrow code, or the finger change code. In steps 1139 to 1144, processing for setting the X coordinate data as display control data of the object is performed according to the arrangement.

Of the above codes, the finger position data having the finger change code is the finger object 2 as described above.
It is for designating the correspondence between 03 and the key to be pressed with the finger indicated by 03. Since the correspondence changes according to the progress of the performance, in other words, the display position of the finger object 203 on the X axis must be changed at any time. Therefore, the display control data is set here. And not. Therefore, the X coordinate data located immediately after the finger change code is ignored.

First, in step 1139, it is determined whether or not the finger change code is placed immediately before the X coordinate data. If the finger change code is placed immediately before,
The determination is NO, the process proceeds to step 1107 in FIG. 11, and the X coordinate data is ignored. On the other hand, otherwise, the determination is yes and the process moves to step 1140.

X where no finger change code is placed immediately before
A frame code is always placed before the coordinate data.
Therefore, in step 1140, the X coordinate data is substituted into the frame [n4] [1], and the subsequent step 1
In 141, the frame [n4] [1] is transferred to the VDP 109. After that, the process proceeds to step 1142.

In step 1142, it is determined whether or not the arrow code is placed immediately before the X coordinate data. If the arrow code is placed immediately before, the determination is YES.
In step 1143, the X coordinate data is changed to the arrow [n
5] [1], and at step 1144, the arrow [n
5] After transferring [1] to the VDP 109, the process proceeds to step 1107 in FIG. Otherwise, the determination is no, without performing the processing of other steps,
Then, the process proceeds to step 1107.

At step 1145, when the determination at step 1138 is NO and the process proceeds, it is determined whether the data designated by the value of the variable AD2 is Y coordinate data (value).
If the data is not Y coordinate data, the determination is NO.
Then, the process proceeds to step 1107 in FIG. Otherwise, the determination is yes and step 1146.
Move to.

As shown in FIG. 3, the Y coordinate data is arranged immediately after the X coordinate data, and the frame code or the arrow code is arranged immediately before the X coordinate data in which the Y coordinate data is arranged immediately after. It In steps 1145 to 1151, Y is determined according to the code placed immediately before the X coordinate data.
A process for setting the coordinate data as display control data of the object is performed.

First, in step 1146, the Y coordinate data is substituted into the frame [n4] [2]. Continued Step 114
In 7, the frames [n4] [2] are transferred to the VDP 109.
Then, the process proceeds to step 1148. Step 114
At 8, it is determined whether the arrow code is arranged immediately before the X coordinate data. If the arrow code is located immediately before, the determination becomes YES, the Y coordinate data is substituted into the arrow [n5] [2] in step 1149, and further the arrow [n5] [2] is transferred to the VDP 109 in step 1150. After that, the process proceeds to step 1107 of FIG. Otherwise, the determination is no and the process moves to step 1107 without executing the process of another step.

In this way, the note object 202, the scale object 208, the finger number object 207, and the frame object 204 are respectively in the note, scale, finger number, frame, and arrow areas secured in the display control area. , And the arrow object 205 or 206
Display control data is stored, and the display control data stored in each of these areas is transferred to the VDP 109, and R
It is stored in the AM 109a. As a result, the scroll display of those objects 202, 204 to 208 is
The address Yw transferred to the VDP 109 is set in a manageable state.

Next, the BG screen display processing executed as step 1101 will be described in detail with reference to the flowchart shown in FIG. The display process is a process for setting display control data of various objects shown in FIG. First, in step 1401, a code indicating the thumb is used as a finger number code for fingers [1] and [0], which are elements of the array variable “fingers” for saving display control data of the finger object 203 (“thumb in the figure”). Code ”). In the following step 1402,
A predetermined X coordinate value is assigned to the finger [1] [1] as a display position on the X axis of the finger object 203 representing the thumb. After that, similarly, as the finger number code, the index finger code indicating the index finger, the middle finger code indicating the middle finger, the ring finger code indicating the ring finger, and the little finger code indicating the little finger are fingered [2-5].
Substituting a predetermined X coordinate value into [0] into fingers [2 to 5] [1] (step 14)
03-1410).

Step 1411 following step 1410
Then, 1 is substituted for the variable n. At step 1412, which moves to the next step, the Y coordinate value fixedly fixed in advance is substituted into the finger [n] [2]. When the substitution is performed, step 14
After incrementing the value of variable n in step 13, step 1
Moving to 414.

In step 1414, it is determined whether the value of the variable n is larger than 5. If the value is greater than 5,
The determination is YES, and the finger [1-5] in step 1415.
[0-2] is transferred to the VDP 109, and then step 14
At 16, the display control data of other objects to be fixedly displayed in the Y-axis direction (such as the scale image 201 and a line extending along the Y-axis) is transferred to the VDP 109, and then the series of processes is ended. On the other hand, if not, the determination is N.
It becomes O and the process returns to step 1412. Thereby,
The processing loop formed in steps 1412 to 1414 is repeatedly executed until the determination in step 1414 becomes YES, and the Y coordinate value is assigned to the fingers [1 to 5] [2].

As described above, the display control data of the object for BG screen display including each finger object 203 is set. The BG screen shown in FIG. 6 represents a state displayed by the display control data set in this way. 15 and 16 are flowcharts of the timer process executed as step 802 in the guide display process shown in FIG. Next, FIG. 15 and FIG.
The timer process will be described in detail with reference to FIG.
The timer process is a process for updating the content to be displayed on the television as time passes (progress of performance).

First, in step 1501, the variable STF
It is determined whether the value of is 1. If the situation is such that performance guidance should be provided, 1 is assigned to the variable STF, so the determination is YES and the process moves to step 1502. If not, the determination is no, and the series of processes ends here.

In step 1502, it is determined whether or not the minimum unit time, which is the minimum time that the note length data in the performance data can represent, has elapsed. If the minimum unit time has elapsed since the start of time counting or when it was determined that the time has elapsed the last time, the determination is YES and step 1503
Then, the value of the variable t into which the note length data has been substituted is decremented, and then step 1504 is entered. If not, the determination is no, and the series of processes ends here.

In step 1504, it is determined whether the value of the variable t is 0. When the value is 0, that is, when it is time to erase the note object 202 representing the note data in which the note length data is substituted for the variable t, the determination is Y.
After ES, the value of the variable AD1 is incremented in step 1505, and the process proceeds to step 1506.
If not, the determination is no, and the series of processes ends here.

In step 1506, it is determined whether or not the data designated by the value of the variable AD1 exists. If there is data to be processed among the performance data, the determination is yes and the process moves to step 1510. Otherwise, the determination is no, in step 1507 0 is assigned to the variable STF, and in step 1508, a command for instructing the mute of all the musical tones being sounded is issued by the tone generator LSI 104.
And the screen displayed on the television is erased in step 1509, and the series of processes is terminated. To delete the screen, for example, set any of the X and Y coordinate values in the display control data of various objects for BG screen display and any of the addresses Xw and Yw to values at which the object is not displayed. , Set the value to VDP
This is done by transferring to 109.

In step 1510 and subsequent steps, the processing for updating the display screen to be displayed on the television is performed at the timing when the note object 202 representing the note data in which the note length data is substituted for the variable t should be deleted. . First, in step 1510, it is determined whether the data designated by the value of the variable AD1 is note length data. If the data is not note length data, the determination is no and the process moves to step 1514 in FIG. Otherwise, the determination is yes, in step 1511 the note length data is substituted for the variable t, and then step 151.
In step 2, the address Yw is updated to a value obtained by adding a predetermined address value to the value up to that point, and in step 1513, the address Yw is transferred to the VDP 109, and then a series of processes is ended. The predetermined address value added to the values of the address Yw up to that point is, for example, a value corresponding to the display interval on the Y axis of two consecutive note objects 202.

In step 1514 of FIG. 16, the variable AD
It is determined whether the data designated by the value of 1 is the finger change code. If the data is not the finger change code, the determination is no and the process moves to step 1525. Otherwise, the determination is yes and the process moves to step 1515.

In step 1515, it is determined whether the finger indicated by the finger change code is the thumb. If the finger it indicates is the thumb, the determination is yes and the process moves to step 1516, 1 is assigned to the variable s, and then step 150 in FIG.
Return to 5. Otherwise, the determination is no and the process moves to step 1517.

In steps 1517 to 1524, it is determined whether the finger indicated by the finger change code is the index finger, the middle finger, the ring finger, or the little finger, and a value is assigned to the variable s according to the type of the determined finger. The processing for doing is performed. Thereby,
If the finger is the index finger, 2 is assigned to the variable s, 3 is the middle finger, 4 is the ring finger, and 5 is the little finger. If the determination in step 1523 is NO, or step 15
When any of 18, 1520, 1522, and 1524 is executed, the process returns to step 1505 of FIG.

At step 1525, when the determination at step 1514 is NO and the process proceeds, it is determined whether the data designated by the value of the variable AD1 is the X coordinate data. If the data is not X coordinate data, the determination is no and the process returns to step 1505 in FIG. As a result, data that does not need to be considered when updating the display control data according to the passage of time (progress of performance) is ignored.
On the contrary, otherwise, the determination is yes and the process moves to step 1526.

In step 1526, it is determined whether the immediately preceding data is the finger change code. When the data designated by the value obtained by decrementing the value of the variable AD1 is the finger change code, the determination is YES, the X coordinate data is substituted for the finger [s] [1] in step 1527, and then step 1528. Then, the finger [s] [1] is transferred to the VDP 109, and X of the finger object 203 corresponding to the value of the variable s is transferred.
After instructing to change the display position on the axis, the process returns to step 1505 in FIG. Otherwise, the determination is no and the process moves to step 1529.

The fact that the immediately preceding data is not the finger change code means that the data is the frame code or the arrow code. That is, the X coordinate data is data that constitutes the hand position data at the timing to be processed. This means that it is time to change the display position of each finger object 203 on the X axis. From this, in steps 1529 to 1539,
A process for changing the display position of each finger object 203 on the X axis is performed.

First, in step 1529, the X coordinate data is converted into the X coordinate value of the finger object 203 of the thumb. In the following step 1530, the X obtained by the conversion is obtained.
The coordinate value is assigned to finger [1] [1]. Step 1531
Then move on. The conversion is performed, for example, by adding the value set for the thumb finger object 203 to the X coordinate data.

In steps 1531 to 1538, the processing of similarly obtaining the X coordinate value and substituting it into the element of the array variable "finger" is performed while switching the type of the target finger object 203. That process ends, that is, step 1
In step 1539 which is performed after executing 538,
Transfer the fingers [1-5] [1] to the VDP 109. Thereby, after instructing to change the display position of each finger object 203 on the X axis, the process returns to step 1505 of FIG.

In the timer processing, the above-mentioned processing is executed. As a result, scroll display of the note object 202, the frame object 204, etc., and change of the display position of the finger object 203 are realized according to the progress of the performance. FIG. 17 is a flowchart showing the flow of processing executed by the VDP 109. Next, the processing executed by the VDP 109 will be described in detail with reference to FIG. The processing along the flow shown in the flowchart is realized by executing a program stored in a built-in ROM (not shown).

First, in step 1701, the CPU 10
It is determined whether or not data is received from 1. If the data is received, the determination is yes and step 1702.
Then, the data is stored in the area of the RAM 109a corresponding to the type, and then the process proceeds to step 1703. Otherwise, the determination is no and the process moves to step 1703 without executing the process of another step.

In step 1703, it is determined whether or not it is the timing (in the drawing, "scan start timing") at which the image data of the display screen should be generated. For example, when it is determined that the timing has come and a predetermined time has elapsed, the determination becomes YES and the step 17
Move to 04. Otherwise, the determination is no and the process returns to step 1701.

At step 1704, 0 is assigned to each of variables x and y. In the following step 1705, the RAM
From the display control data stored in 109a,
Display control for setting the display position within the display range of the object where the value obtained by adding the value of the variable x to the value of the address Xw is the X coordinate value, and the value obtained by adding the value of the variable y to the value of the address Yw is the Y coordinate value Search for data. In the next step 1706, it is determined whether or not the corresponding display control data has been extracted as a result of the search. If the corresponding display control data can be extracted, the determination becomes YES, and in step 1707, the image data of the object indicating the display position is displayed in the DP-RAM 1 according to the display control data.
After reading from 08 and arranging it on a work memory (hereinafter referred to as a work memory), the process proceeds to step 1708. Otherwise, the determination is no and the process moves to step 1708.

At step 1708, the value of the variable x is incremented. In the next step 1709, it is determined whether the value obtained by adding the value of the variable x to the value of the address Xw is equal to or larger than the display end, that is, the maximum value on the X axis. If the added value is greater than or equal to the maximum value, the determination is yes and step 1710.
Move to. Otherwise, the determination is no and the process returns to step 1705.

At step 1710, 0 is substituted for the variable x. In the following step 1711, the value of the variable y is incremented. In step 1712, which is subsequently performed, it is determined whether the value obtained by adding the value of the variable y to the value of the address Yw is equal to or larger than the display end, that is, the maximum value on the Y axis. If the added value is greater than or equal to the maximum value, the determination is YES, it is determined that the generation of the image data of the display screen is completed, the generated image data is output to the converter 110, and then the process returns to step 1701. Otherwise, the decision is N
It becomes O and returns to step 1705.

The generation of the image data of the display screen by the processing loop formed in steps 1705 to 1712 is
Although not particularly shown, after performing only the object for the BG screen, only the object for the extraction screen is performed as the target. If only the object for the BG screen is targeted, in step 1705,
The respective values of the addresses Xw and Yw are not taken into consideration, and the display control data that makes the display position designated by the values of the variables x and y within the display range of the object is searched. The image data of the object is arranged in the work memory by overwriting it. In other words, the extraction screen is overwritten on the BG screen. As a result, scale image 2
01, each finger object 203, and the like, the scroll display of various objects such as the note object 202, the frame object 204, and the scale object 208 is realized while preventing the position on the Y axis on the display screen from changing (FIG. 2).

The object for the BG screen is not displayed by setting at least one of the X coordinate value and the Y coordinate value of the object at the position above the display end. The object for the extraction screen is not displayed by setting the address Xw at a position above the display end or by setting the value of the address Yw at a position where no object exists in the display range.
From this, in the object for the BG screen, the X
At least one of the coordinate value and the Y coordinate value is set to a value at the position above the display end, and in the object for the extraction screen, the address Xw is set to the position above the display end or the address Yw.
The display screen is erased by setting the value at a position where there is no object whose display range is w. <Second Embodiment> In the first embodiment, as shown in FIG.
As shown in FIG. 5, one of the plurality of frame objects 204 is selected and displayed according to the length of the period during which the key can be pressed without moving the hand itself. On the other hand, in the second embodiment, there is only one type of frame object 204,
It is designed to be displayed unconditionally.

The structure of the electronic keyboard instrument equipped with the performance guide device according to the second embodiment is basically the same as that of the first embodiment. There are many common operations. For this reason, for the same or basically the same as the first embodiment, the reference numerals given in the first embodiment are used as they are, and only the parts different from the first embodiment will be described. I decided to.

FIG. 18 is a diagram for explaining the performance guide method according to the second embodiment. In the second embodiment,
As shown in FIG. 18, the frame object 204 has a length on the Y axis that can accommodate only one note object 202. As a result, the frame object 204 is displayed in units of notes (musical sounds) with different sounding start timings. Other objects are displayed as in the first embodiment.

Even if only one type of frame object 204 is displayed, the player can easily recognize the position where the hand should be placed from the display position, as shown in FIG. Therefore, the same effect as that of the first embodiment can be obtained. FIG. 19 is a diagram for explaining the structure of performance data.

In the second embodiment, the frame object 2
Since there is only one type of 04 and there is no need to insert the frame code into the performance data, the structure of the hand position data is the first.
It differs from that in the embodiment (see FIG. 3). As shown in FIG. 19, in the hand position data located at the beginning of the performance data, a hand code is assigned instead of the frame code, and the frame code is omitted from the hand position data at other positions. Since the frame object 204 is displayed for each note object 202, the finger position data is omitted. The types of the hand position data can be discriminated by using two types of codes, the hand code and the arrow code. Regarding the image data for displaying the object, as shown in FIG.
There is only one image data for displaying the frame object 204.

Next, the operation will be described. The objects for processing and displaying the hand position data constituting the performance data are a frame object 204 and an arrow object 205,
Alternatively, it is 206. All of these display control data are generated at the start of the performance guide. Therefore, in the second embodiment, step 1 in the initial setting process shown in FIG.
The initial screen generation process executed as 006 is different from that of the first embodiment. On the other hand, the finger position data omitted from the performance data in the second embodiment is data that should be processed according to the progress of the performance, and is shown in FIGS. The timer process does not necessarily have to change as it is omitted. Therefore, only the initial screen generation process in the second embodiment will be described with reference to the flowcharts shown in FIGS. 21 to 23.

First, in step 2101, a BG screen display process for displaying a BG screen as shown in FIG. 6 is executed. In the following step 2102, the variable AD2 is set to
Substitute a value indicating the start address of performance data. In step 2103, which proceeds to the next step, variables n1 to n5, M
Substitute 0 for each. Then, the process proceeds to step 2104.

At step 2104, the performance data (see FIG.
9), the data designated by the value of the variable AD2 (indicated as "MEM [AD2]" in the drawing) is a hand code. If the data was not hand code,
The determination is NO and the process moves to step 2111. Otherwise, the determination is yes and step 210.
Go to 5.

At step 2105, the hand code is stored in the display control area as a hand [0] which is an element of the array variable "hand". Next, in step 2106, the hand code is transferred to the VDP 109. When you transfer it,
After incrementing the value of the variable AD2 in step 2107, the process proceeds to step 2108.

In step 2108, it is determined whether or not the data designated by the value of the variable AD2 exists. If there is data to be processed among the performance data, there is data specified by that value, so the determination is NO and the process returns to step 2104. Thereby, all the data to be processed is processed. On the other hand, otherwise, the determination is yes and step 2109
At step 2110, the initial values are respectively substituted into the addresses Xw and Yw, and they are transferred to the VDP 109, and R
After storing the data in the AM 109a, the series of processes ends.

By transferring the addresses Xw and Yw to the VDP 109, the display control data necessary for generating the image data (display screen) is stored in the RAM 109a. Thereby, the VDP 109 starts its generation. In step 2111 where the determination in step 2104 is NO and the process shifts, it is determined whether or not the data designated by the value of the variable AD2 is an arrow code. If the data is the arrow code, the determination is YES, the value of the variable n5 is incremented in step 2112, and the arrow code is changed to the arrow [n5] in step 2113.
After substituting for [0], the process proceeds to step 2106, and the arrow [n5] [0] is transferred to the VDP 109. Otherwise, the determination is no and step 211 in FIG.
Go to 4.

At step 2114, it is determined whether the data designated by the value of the variable AD2 is pitch data. If the data is not pitch data, the determination is no and the process moves to step 2134 in FIG. Otherwise, the determination is yes and the variables n1, n2, and n4 are each incremented (step 2
After 115 to 7), the process proceeds to step 2118.

At step 2118, the note [n1]
Substitute the note code in [0]. When the substitution is performed, the process proceeds to step 2119, and a chord indicating a pitch name corresponding to the pitch indicated by the pitch data is generated as a scale code.
After that, in step 2120, the scale code is changed to the scale [n
2] Substituting into [0], the process proceeds to step 2121.

At step 2121, the frame code is set to the frame [n
4] Substitute in [0]. In the next step 2122, the X coordinate value corresponding to the pitch indicated by the pitch data is calculated, and in the subsequent step 2123, the X coordinate value is substituted into the note [n1] [1]. In step 2124, which is executed after the substitution, the fixed X coordinate value for the scale object 208 is substituted into the scale [n2] [1]. Step two
After that, the process proceeds to 125.

In step 2125, the most recently read X coordinate data is substituted into the frame [n4] [1]. Thereby, after maintaining the display position on the X axis specified by the hand position data located immediately before, the process proceeds to step 2126,
The Y coordinate value is calculated using the value of the variable M. After that, the calculated Y coordinate value is set to the note [n1] [2] and the scale [n
2] and [2], respectively (step 212
7, 2128), and proceeds to step 2129.

In step 2129, the value of the variable M is used to calculate the Y coordinate value for displaying the frame object 204. In step 2130 to be transferred next, the calculated Y coordinate value is substituted into the frame [n4] [2]. When the substitution is performed, next, notes [n1] [0-2] and scales [n2] [0
2] and the frame [n4] [0-2] to the VDP10, respectively.
9 (steps 2131 to 3), and after the transfer, the procedure moves to step 2107 in FIG.

Thus, according to the second embodiment,
When the pitch data forming the note data is read from the performance data, display control data for the frame object 204 in addition to the note object 202 and the scale object 208 are generated and stored in the display control area. .

In step 2134 of FIG. 23, in which the determination is NO in step 2114, the variable AD2 is set.
It is determined whether the data specified by the value of is the note length data. If the data is not note length data, the determination is no and the process moves to step 2136. Otherwise, the determination is yes, after incrementing the value of variable M in step 2135, then step 2 in FIG.
Move to 107.

At step 2136, it is determined whether the data designated by the value of the variable AD2 is a finger number code. If the data is not the finger number code, the determination is no and the process moves to step 2143. Otherwise, the determination is yes and the process moves to step 2137.

In steps 2137 to 2142, FIG.
Since the processing similar to that of steps 1132 to 1137 shown in 1 is performed, detailed description thereof will be omitted. Step two
After execution of 142, the process moves to step 2107 of FIG. As shown in FIG. 19, the X coordinate data and the Y coordinate data are arranged after the hand code or the arrow code. If the code is an arrow code, unlike hand codes,
The arrow object 205 or 206 must be displayed. From this, steps 2143 to 21
At 49, a process for dealing with this is performed.

First, in step 2143, the variable AD2
It is determined whether the data designated by the value of is the X coordinate data (value). If the data is not X coordinate data, the determination is no and the process moves to step 2147. Otherwise, the determination is yes and step 2144.
Move to.

In step 2144, it is determined whether or not the arrow code is placed immediately before the X coordinate data. If the arrow code is placed immediately before, the determination is YES.
Then, the X coordinate data is substituted for the arrow [n5] [1] (step 2145), and then the arrow [n5] [1].
Is transferred to the VDP 109 (step 2146), and the process proceeds to step 2107 in FIG. Otherwise, the determination is no and the process moves to step 2107.

At step 2147, when the determination at step 2143 is NO and the process proceeds, it is determined whether the data designated by the value of the variable AD2 is Y coordinate data (value).
If the data is not Y coordinate data, the determination is NO.
Then, the process proceeds to step 2107 in FIG. Otherwise, the determination is yes and step 2148.
Move to.

In step 2148, it is determined whether or not the arrow code is located immediately before the X coordinate data, that is, two positions before the Y coordinate data. If the arrow code is placed two positions before, the determination is yes and step 214
After substituting the Y coordinate data into the arrows [n5] [2] in 9,
The procedure moves to step 2146 and the arrow [n5]
[2] is transferred to the VDP 109. After that, the process proceeds to step 2107 of FIG. Otherwise, the determination is no and the process moves to step 2107 without performing the process of another step.

As described above, the musical note, scale, finger number, frame, and arrow objects 202, 204-2.
Display control data No. 08 is stored in the display control area. Thereby, those objects 202, 204
~ 208 are displayed as shown in FIG. 18, and the VDP 109 is displayed.
It is scrolled by updating the value of the address Yw transferred to the. <Third Embodiment> In the first and second embodiments, scrolling is performed only in accordance with the contents of performance data. On the other hand, in the third embodiment, the user confirms the key actually pressed by the user according to the situation, and manages the progress of scrolling in a manner that reflects the confirmation result.

By confirming the key actually depressed, it is possible to confirm whether or not the user is depressing the key to be depressed at that time. Therefore, when the confirmation result is used for managing the progress of the scroll (performance guide), it is possible to perform the scroll in a form that matches the performance being performed by the user. For a user who has difficulty pressing the key to be pressed at the timing when the key should be pressed, scrolling can be performed at an appropriate playing speed for the user. That is why the confirmation result of the key actually pressed is used for managing the progress of scrolling.

A key to be depressed by moving the position of the hand requires a complicated movement as compared with a case of depressing a key to be depressed without moving the position of the key. The key becomes more difficult. This means that a key to be moved by moving the hand position is easily confused by the key depression. From this, in the third embodiment, paying attention to this fact, the position of the hand is moved, and confirmation of the key to be actually pressed is started at the timing when the next key should be pressed. The scrolling is stopped until it is confirmed that the key to be pressed is pressed.

If the progress of scrolling is stopped in this manner, the user's performance (key depression of a key to be depressed) is awaited in a situation where the performance is likely to be delayed, but the performance is considered to be relatively easy. Under certain circumstances, delaying scrolling will be avoided. As a result, the user can scroll at an appropriate speed while feeling more comfortable.

The structure of the electronic keyboard instrument equipped with the performance guide device according to the third embodiment is basically the same as that of the first embodiment. There are many common operations. For this reason, like the second embodiment, the same or basically the same as the first embodiment will be denoted by the same reference numerals as in the first embodiment, Only parts different from the first embodiment will be described.

FIG. 24 is a diagram for explaining the performance guide method according to the third embodiment. In the third embodiment,
As shown in FIG. 24, an object 2401 in which five black circles are arranged side by side in the X-axis direction in the frame is arranged at a position indicating the timing at which the hand should be moved, and scrolling is performed. The five black circles inside are all
It is arranged to request a key depression corresponding to the display position on the X axis. That is, the object 2401
Are arranged to request an operation of pressing five keys with five fingers each time the position of the hand is moved. Therefore, the object 2401 will be hereinafter referred to as an operation object 2401.

As described above, in the third embodiment, the user is requested to press the five keys, but this requires that the hand be moved to the position to move the five keys. This is because it must be done. That is, it is possible to confirm that the hand has been moved to the position to be moved, by confirming the pressed key. Naturally, the operation requested to the user is not limited to the operation unrelated to the performance, such as pressing the five keys. It may be a key to be pressed next. The request for the operation may be made by not displaying the object for that purpose by scrolling, but by displaying the information indicating the content of the operation at any time.

In order to scroll-display the operation object 2401 shown in FIG. 24, performance data as shown in FIG. 25 is prepared in the third embodiment. 3 is different from the performance data shown in FIG. 3 in that a shift code for instructing the display of the operation object 2401 is arranged after the hand position data. The image data of the operation object 2401 is prepared in the B-side area as shown in FIG. As shown in FIG. 27, the display control data is stored in the display control area with a shift area reserved for the storage. The data stored in the shift area is handled as a two-dimensional array variable like other areas. The array variable name will be referred to as “shift” hereinafter, and the element will be described as “shift” with two parentheses.

Next, the operation will be described. In the third embodiment, as shown in FIG. 24, an operation object 2401 is added as an object to be displayed. The performance guide (scroll) is the operation object 24
The operation indicated by 01 is waited for by the user before proceeding. From these, the keyboard processing shown in FIG. 9, the initial screen generation processing shown in FIGS. 11 to 13, FIG.
Also, the timer processing shown in FIG. 16 is different from that of the first embodiment. Therefore, only those processes will be described in detail.

FIG. 28 is a flow chart of keyboard processing in the third embodiment. First, the keyboard processing in the third embodiment will be described in detail with reference to FIG. The keyboard process is executed as step 703 in the overall process shown in FIG.

First, in step 2801, the keyboard 107
The detection circuit is instructed to perform scanning, and the scanning result is received. In step 2802, which follows, the scanning result is compared with that received last time, so that the keyboard 10
The presence / absence of a key whose state has changed in 7 and the content of the change are determined. If there is no change in the state of each key on the keyboard 107, that effect is determined, and the series of processing ends here. If there is a change due to a key depression (ON) in each key, it is determined and the process proceeds to step 2805. If there is a change due to key release (OFF) in each key, that effect is determined, and note-off event data for instructing the mute of the musical tone of the pitch assigned to the key that detected the change is recorded. Create the sound source LS
Sent to I104 (steps 2803, 2804)
After that, a series of processing is ended.

At step 2805, the variable TAIKIF is set.
It is determined whether the value of is 1. The variable TAIKIF is a progress management variable prepared to stop the progress of the performance guide until the user performs an operation (here, five key depression) instructed by the operation object 2401.
“1” is a value indicating that the progress should be stopped until the user performs the operation. From this, if it is that situation, the determination is yes and step 280
Move to 7. Otherwise, the determination is no, after the note-on event data for instructing the pronunciation of the musical tone of the pitch assigned to the key pressed by the user is created (step 2806), the process proceeds to step 2804. The data is sent to the sound source LSI 104.

At step 2807, it is determined whether or not 5 keys are simultaneously pressed. After the change due to the key depression is determined in step 2802, if there are five keys for which the change due to the key release has not been determined, the determination becomes YES and the process proceeds to step 2808. Otherwise, the determination is no and the process moves to step 2806.

At step 2808, the key is depressed by 5
The combination of the values indicating the pitches of the keys is the array variable NOTE
It is determined whether or not the combinations of the values assigned to the respective elements NOTE (0) to (5) of are matched. Array variable NOT
E is a variable prepared to hold a value indicating the pitch of a key requesting a key depression with the operation object 2401.
When assigning 1 to the variable TAIKIF, a value indicating the pitch of the key requesting key depression with the operation object 2401 is assigned to these elements. From this, when the user presses the five keys requested to be pressed by the operation object 2401, the determination becomes YES and the process moves to step 2809. Otherwise, the determination is no and the process moves to step 2806.

At step 2809, the variable TAIKIF is set.
Substitute 0 for. In the following step 2810, the address Yw is calculated in order to scroll the operation object 2401 and the calculated address Yw is set to VDP1.
It transfers to 09. A series of processing is ended thereafter.

In the third embodiment, as described above, after confirming that the user has actually operated the operation requested by the operation object 2401, the variable TAIKI is changed.
Substitute 0 for F. Thereby, the operation object 24
The progress of the performance guide is temporarily stopped after the timing of requesting the operation by 01, that is, from the time 1 is assigned to the variable TAIKIF until the user actually performs the operation.

Next, the initial screen generation process will be described. By inserting the shift code into the performance data, the display control data of the operation object 2401 must be generated and stored in the shift area shown in FIG. In the third embodiment, step 1 shown in FIG.
When the determination in step 145 is NO, the process moves to step 2901 shown in FIG. 29 and the subsequent processes are executed. Operation object 240 in the shift area by substituting data for the elements of array variable "shift"
A variable n6 is prepared to store the display control data of 1, and 0 is substituted for the variable n6 in step 1103 of FIG.

First, in step 2901, the variable AD2
It is determined whether the data specified by the value of is a shift code. If it is not the data shift code, the determination is N.
When it becomes O, the process proceeds to step 1108 of FIG. Otherwise, the determination is yes and step 290.
Move to 2.

At step 2902, the value of the variable n6 is incremented. In the following step 2903, the shift code is assigned to shift [n6] [0]. In the next step 2904, the X coordinate data in the hand position data located immediately before is substituted into shift [n6] [2]. After that, the Y coordinate data in the hand position data is substituted for shift [n6] [3] (step 290).
5) and increments the value of the variable M (step 290
6) Further, the values of shift [n6] [1 to 3] are transferred to the VDP 109 as display control data (step 290).
7) After that, it transfers to step 1108 of FIG.

In this way, the display control data of the operation object 2401 designated by the shift code is generated and stored in the shift area secured in the display control area (see FIG. 27) and the RAM 109a of the VDP 109. It Based on the generated display control data, the operation object 2401 displays the frame object 204 displayed by the hand position data located immediately before the shift code.
Will be displayed at the bottom of.

The array variable NOTE and the variable TAIKIF referred to in the keyboard processing shown in FIG. 28 are defined in the timer processing. Next, the timer processing according to the third embodiment will be described in detail with reference to the flowcharts shown in FIGS. 30 and 31.

Most of the timer processing in the third embodiment is common to that in the first embodiment shown in FIGS. 15 and 16. For this reason, portions different from the first embodiment are extracted and shown in FIGS. 30 and 31. The processes used in the steps that have not changed from those in the first embodiment have the same reference numerals used in the description of the first embodiment. Here, only the parts different from the first embodiment will be described.

If 1 is assigned to the variable STF and the result of the determination in step 1501 is YES, the process proceeds to step 3001. In step 3001,
It is determined whether or not the value of the variable TAIKIF is 0. If the user is not in a situation of requesting the performance operation represented by the operation object 2401, 0 is assigned to the variable TAIKIF, so that the determination is YES and step 1502
Move to. Otherwise, the determination is no,
Here, a series of processing ends. In that way, the variable T
While 1 is assigned to AIKIF, decrement of the variable t, that is, timing of the performance time is avoided, and the performance operation requested by the operation object 2401 is handled separately from the actual performance.

In the first embodiment, if the determination in step 1525 shown in FIG. 16 is NO, the process returns to step 1505 in FIG. On the other hand, in the third embodiment,
If the determination is NO, step 300 shown in FIG.
Move to 2. In step 3002, the variable AD1
It is determined whether the data specified by the value of is a shift code. When the data is shift data, that is, when it is time to request the performance operation represented by the operation object 2401 displayed by the user to the user,
The determination is yes and the process moves to step 3003. Otherwise, the determination is no and the process returns to step 1505 of FIG.

At step 3003, the variable TAIKIF
Substitute 1 for. In the following step 3004, a key depression is requested by the operation object 2401 from the X coordinate data immediately before in the performance data (see FIG. 25), that is, the X coordinate data in the hand position data immediately before the shift code. A value indicating each pitch of the five keys present is obtained, and in the subsequent step 3005, the obtained value is substituted into the elements NOTE (1) to (5) of the array variable NOTE. afterwards,
A series of processing ends.

By executing the keyboard processing shown in FIG. 28, the element NOT is added to the variable TAIKIF in which 1 is substituted.
0 is substituted after confirming that the combination of the values assigned to E (1) to (5) matches the combination of the values indicating the pitch of the depressed key. Thereby, the variable T
While 1 is assigned to AIKIF, the progress of the performance guide is stopped without measuring the performance time.

In the third embodiment, the progress of the performance guide is stopped until the user performs the performance operation requested by the operation object 2401, but the stop may be performed only for a predetermined time. good. Alternatively, it may be handled by slowing the speed of measuring the playing time (here, the time interval for decrementing the variable t is made long). In this way, various modifications can be made.

The performance guide device according to the third embodiment is one in which the present invention is applied to a performance guide device mounted on an electronic keyboard instrument, but the applicable performance guide device is one mounted on an electronic keyboard instrument. It is not limited to. Since many keyboard musical instruments have a function of outputting the contents of the musical performance operation performed by the user on the keyboard as MIDI data, the present invention is also applied to a performance guide device not mounted on the keyboard musical instrument. can do.

This embodiment (first to third embodiments)
Then, only the pitch name corresponding to the white key is arranged in the scale image 201 (see FIG. 2, FIG. 18, or FIG. 24), but it may be arranged in it including the symbol corresponding to the black key. Even if only the note name corresponding to the white key is arranged, an object representing an accidental symbol such as “#” or “♭” is arranged near the note object 202, or the display color is changed. It is possible to teach a black key depression.

In the performance, it is often the case that the position of the hand is not moved and only the finger is moved to press the key. From this,
