FIG. 3 is a view showing an example of a display on the display device 9. As shown in FIG. 3, a reduced display keyboard 31 showing a state in which a player looks down on the keyboard 1 and keys to be operated are shown. Piano roll paper-like area representing the operation timing (hereinafter, this area is referred to as “piano roll paper”) 32
Is displayed. (A) shows a display state at a certain point in time, and (b) shows a display state after a predetermined time has elapsed from the display state of (a).

The reduced display keyboard 31 is a reduced display of the state in which the player looks at the keyboard 1 when heading to the keyboard 1, and the reduced display keyboard 31 has, like the keyboard 1,
88 keys are displayed.

The piano roll paper 32 displays a key operation range from a key press to a key release with a vertical bar, and the vertical bar scrolls according to the reproduction of the automatic performance data. From the time when the lower limit exceeds the scroll area 32a to the time when the upper limit of the vertical bar disappears from the scroll area 32a, a floor name / note name display area 32b for displaying a floor name or a note name of a key corresponding to the vertical bar is provided. ing. The figure shows an example in which a note name is displayed. Hereinafter, the “vertical bar” is referred to as a “scroll bar”.

The scroll area 32a is divided into the number of white keys of the reduced display keyboard 31 and at equal intervals. When the key to be operated is a white key, the scroll bar is divided into a plurality of divided areas. It is displayed at a position corresponding to the key to be operated and the timing to be operated on the area corresponding to the key. On the other hand, when the key to be operated is a black key, the scroll bar crosses the position across the white key and the white key, that is, the divided area corresponding to each white key, similarly to the actual keyboard 1. The position is displayed at a position corresponding to the key to be operated and the timing to be operated.

The scroll bar has a different color according to the left hand data and the right hand data (for example, green when the scroll bar corresponds to the left hand data, and green when the scroll bar corresponds to the right hand data). Displayed in yellow and different display modes according to the black key and the white key (for example, a dark color when the scroll bar corresponds to the black key, and a scroll bar corresponding to the white key when the scroll bar corresponds to the black key) Is displayed in pale color). Further, the floor name / note name of the key is displayed in white below the scroll bar. In the drawings, since the actual display color cannot be expressed, the display mode is changed (that is, the direction of the oblique line and the thickness of the oblique line are changed) to distinguish each color.

As mentioned above, the floor name / note name display area 32b displays the displayed floor name / note name in the scroll area 32a.
When the scroll bar goes down, it is an area for displaying the floor name / note name until the scroll bar disappears from the scroll area 32a, and after the lower limit of the floor name / note name reaches the lower limit of the scroll area 32a, Until the upper limit of the floor name / note name disappears from the scroll area 32a, the floor name / note name is the scroll area 32a and the floor name / note name display area 32b.
While scrolling between, the floor name / note name completely disappears from the scroll area 32a and the scroll bar is still displayed in the scroll area 32a.
The floor name / note name is stopped and displayed at a predetermined position in the floor name / note name display area 32b. When the floor name / note name is in the scroll area 32a, it is displayed in white as described above,
When in the floor name display area 32b, for example, it is displayed in purple.

The timing at which the player should press the key is such that the lower limit of the scroll bar is the lower limit of the scroll area 32a, that is, the scroll area 32a and the floor name / note name display area 3.
This is the time when the boundary line with 2b is reached. At this time, the color of the key on the reduced display keyboard 31 to be depressed is colored and displayed in the same color as that of the scroll bar. In response to this, when the player presses the keyboard 1, if the key is pressed correctly, the color of the key on the reduced display keyboard 31 is changed to, for example, blue, while if the key is wrong, The color of the key on the reduced display keyboard 31 is changed to, for example, red.

FIG. 4 is a view showing an example of a display displayed on the display device 9 when the player selects the enlarged display mode. As shown in FIG. A key range (key range) is selected (21 white keys in this embodiment), and this range is such that the size of each key is substantially the same as the size of each key of the actual keyboard 1. It is displayed as enlarged. The enlarged display is the keyboard 31 'in the selected key range and the piano roll paper 32', and the reduced display keyboard 31 is also displayed in the display state of FIG. Here, the reduced display keyboard 31 is displayed so that the player can easily understand which part of the keyboard 1 corresponds to the selected key range, whereby the key to be pressed can be instantaneously determined. This is for the sake of understanding. Further, in this key area, as described later, automatic performance data of a guide track ahead of a predetermined number is pre-read, and according to the pre-read result, an optimal range, that is, all of the note event data of the pre-read automatic performance data, Is selected.

The control processing executed by the electronic keyboard instrument configured as described above will be described below with reference to FIGS.

FIG. 5 is a flowchart showing the procedure of a main routine executed by the electronic keyboard instrument of the present embodiment, in particular, the CPU 5.

In the figure, first, a graphic-related element (not shown) such as a VRAM (video ram) for displaying an image on the display device 9, a MID II / F 13, a communication I
/ F14, timer 8, etc., and initial settings such as opening a music data file of the automatic performance music to be performed are performed (step S1). In the present embodiment, a plurality of automatic performance music data are stored in the FDD in a file format, and one (or a plurality of) music data files are read out in accordance with a player's instruction, and are stored in a predetermined position of the RAM 7. The music is loaded into the secured music data storage area. A plurality of pieces of automatic music data may be stored in the ROM 6 in advance and selected from them, or supplied from the CD-ROM drive 12 or supplied from outside via the MID II / F 13 or the communication I / F 14. You may make it.

Next, depending on the display mode selected by the player, the screen display of FIG. 3 (display of the reduced display keyboard 31 and the piano roll paper 32) or the screen display of FIG. 4 (reduced display keyboard 31, enlarged display) One of the keyboard 31 'and the piano roll paper 32') is drawn (step S2). Actually, other screen displays may be performed, but for convenience of explanation, these two screen displays are limited.

Next, it is determined whether there is a switch event of the panel switch 2 (step S3). If there is a switch event in this determination, a panel switch event processing subroutine (details of which will be described later with reference to FIG. 6) for performing a process corresponding to the switch event is executed (step S4), while there is no switch event. In some cases, the process skips step S4 and proceeds to step S5.

In step S5, it is determined whether or not the value of the coincidence progress timer, which is a soft timer secured at a predetermined position in the RAM 7, is greater than "0". Here, the coincidence progress timer means a buffer 1 corresponding to a note-on event of the automatic performance data and a key press event of the player.
And 2 (FIG. 14) for counting the elapsed time time (KC) after storing the key code KC. Buffers 1 and 2 are both RA
M7 is a buffer secured at a predetermined position, and as shown in FIG. 14, a maximum of 32 key codes KC and an elapsed time time after storage for each key code KC, respectively.
(KC).

In the determination of step S5, the match progress timer>
If the value is 0, a match progress timer processing subroutine described later with reference to FIG. 8 is executed (step S6). If the match progress timer ≦ 0, step S6 is skipped and the process proceeds to step S7.

In step S7, it is determined whether or not the value of a reproduction processing timer, which is a soft timer secured at a predetermined position in the RAM 7, is "0" or less in order to reproduce the automatic performance data. In this determination, when the reproduction processing timer ≦ 0, a reproduction processing subroutine described later with reference to FIG. 9 is executed (step S8), while when the reproduction processing timer> 0, step S8 is skipped and the process proceeds to step S9.

In step S9, in order to attach the scroll bar and bar lines to the piano roll paper 32, R
It is determined whether or not the value of a pre-set timer which is a soft timer secured in a predetermined area of the AM 7 is equal to or less than "0". If it is determined in this determination that the pre-installation timer ≦ 0, a pre-installation process subroutine described later with reference to FIG.
0) On the other hand, when the pre-installed timer> 0, step S1
The process skips 0 and proceeds to step S11.

In step S11, the piano roll paper 32
The value of the scroll timer, which is a soft timer secured at a predetermined position in the RAM 7, is
It is determined whether or not: In this determination, when the scroll timer ≦ 0, a scroll processing subroutine described later with reference to FIG. 11 is executed (step S12). On the other hand, when the scroll timer> 0, step S12 is skipped and the process proceeds to step S13.

In step S13, it is determined whether or not there is a key event from the keyboard 1, that is, a key press event or a key release event. In this determination, when there is a key event, a key processing subroutine described later with reference to FIG. 12 is executed (step S14). When there is no key event, step S14 is skipped and step S1 is performed.
Go to 5.

In step S15, after executing other processing other than the above-described processing, the process proceeds to step S3, and the above-described processing is repeated.

It should be noted that a match progress timer, a reproduction processing timer,
The counting of the roll advance timer and the scroll timer is performed by timer interrupt processing described later with reference to FIG.

FIG. 6 is a flowchart showing a detailed procedure of the panel switch event processing subroutine in step S4.

In the figure, first, various modes are set in accordance with a switch event generated by a player operating the panel switch 2 (step S2).
1). As the mode set at this time, for example,
There are an automatic performance mode for instructing start / stop of automatic performance, a guide mode for instructing on / off of a performance guide function, a part setting mode for instructing valid / invalid of right / left hand parts, and the like.

Next, it is determined whether or not an automatic performance start instruction has been issued (step S22). When this instruction has been issued, a prefetch processing subroutine described later with reference to FIG. 7 is executed (step S23). Then, on the display screen selected in accordance with the display mode (display screen of FIG. 3 or 4), for example, the scroll bar, floor name / tone name, etc. After performing the initial drawing for displaying the initial state (step S24), the panel switch event processing subroutine ends.

On the other hand, if it is determined in step S22 that the automatic performance start instruction is not issued, the panel switch event processing subroutine is immediately terminated.

FIG. 7 is a flowchart showing a detailed procedure of the prefetching subroutine of step S23. This prefetching subroutine is secured at a predetermined position in the RAM 7 in order to generate the display screen of FIG. The data is processed and saved in the read-ahead buffer.

In the figure, first, the head of the automatic performance data instructed to perform is sought, and a file pointer seek process is performed in which a file pointer is adjusted to that position (step S31). In the present embodiment, since the automatic performance data is stored in the music data storage area of the RAM 7, the file pointer seek process allows the file pointer to indicate the head address position of the automatic performance data. Become.

In the following step S32, various variables used in this subroutine, such as a write pointer used when writing (saving) data in the prefetch buffer, are initialized.

Next, the file pointer is advanced by "1", the event data stored at the position indicated by the file pointer is read (step S33), and it is determined whether or not the read event data is the file end data. (Step S34). In this determination, when the read event data is file end data, the present prefetch processing subroutine is immediately terminated. On the other hand, when the read event data is not file end data, the note-on / off event data is determined. It is determined whether or not it is (step S35).

If it is determined in step S35 that the read data is note-on / off event data, it is determined whether the data is for a guide track, that is, for MIDI channel 1 or 2 (step S36). .

If it is determined in step S36 that the read note-on / off event data is for the guide track, the write pointer is advanced by "1" and the write pointer is moved to the position of the pre-read buffer indicated by the write pointer. On the other hand, if the read note-on / off event data is not for the guide track, the process proceeds to step S41.

On the other hand, if it is determined in step S35 that the read data is not the note-on / off event data, it is determined whether or not the data is the duration data (step S37).

If it is determined in step S37 that the read data is duration data, the duration data summarizing process is performed (step S38).
Proceed to step S39. Here, the duration data summarizing process means that when note event data of another track (channel) is included between note event data of a guide track, a plurality of duration data are inserted between the note event data of the guide track. If it is included, it refers to a process of combining the plurality of duration data into one and generating duration data between note event data of the guide track. Such processing is performed because the data stored in the prefetch buffer is only the event data related to two channels (guide tracks) out of the 16 channels. This is because the data may be divided into duration data, and in such a case, it is more convenient to combine the plurality of duration data into one and handle it as one duration data.

On the other hand, if it is determined in step S37 that the read data is not duration data, it is determined whether or not the data is bar line data (step S40).

If it is determined in step S40 that the read data is bar line data, the process proceeds to step S39. If the read data is not bar line data, the process proceeds to step S41. ,
That is, it is determined whether the data is smaller than the maximum value of the data that can be stored in the prefetch buffer. If the capacity of the pre-read buffer is sufficiently larger than the capacity of the area for storing the automatic performance data, this step S41 is executed.
There is no need to determine

If it is determined in step S41 that the number of prefetches <the set number, the flow returns to step S33 to repeat the above-described processing. If the number of prefetches ≧ the set number, the prefetch processing subroutine ends.

FIG. 8 is a flowchart showing a detailed procedure of the match progress timer processing subroutine of step S6 in FIG.

In the figure, first, buffer 1 or 2
When the key depression event data (key code KC) is stored in the storage device, the value of the match progress timer is added to the elapsed time data time (KC) stored along with the key code KC, and the match progress timer is set. A guide timer process for clearing is performed (step S51). Here, as described above, the buffer 1 is a buffer for writing a key code KC corresponding to a key-on event generated by a player's key depression, and the writing of the key code KC is performed in the key processing of step S14. This is performed in a subroutine (the details of which will be described later with reference to FIG. 12). On the other hand, the buffer 2 is a buffer for writing the key code corresponding to the note-on event of the guide track generated by the reproduction of the automatic performance data, as described above. The writing of the key code KC is performed in the step S8. This is performed in a reproduction processing subroutine (the details of which will be described later with reference to FIG. 9). The data written in the buffer 1 is deleted when the player releases the key, and the data written in the buffer 2 is deleted when a note-off event occurs.

Next, it is determined whether or not the reproduction of the automatic performance data is paused (step S52).
Specifically, data stored in buffer 1 is compared with data stored in buffer 2 and buffer 2 is compared.
If the key code KC which has been stored for a predetermined time after the key code KC has not been stored in the buffer 1 is determined to be a pause (pause), the key code KC stored in the buffer 2 but not stored in the buffer 1 If any of the key codes KC stored in the buffer 2 has been stored in the buffer 1 if there is any of which has not passed the predetermined time, it is determined that the process is in progress (no pause).

If it is determined in step S52 that a pause has been made, a pause request flag FPAUSE indicating a pause request of "1" is set ("1") (step S52).
53) After that, the match progress timer processing subroutine ends.

On the other hand, if it is determined in step S52 that no pause is to be made, the pause request flag FP
AUSE is reset ("0") (step S54).
Thereafter, the present match progress timer processing subroutine ends.

FIG. 9 is a flowchart showing a detailed procedure of the reproduction processing subroutine of step S8 in FIG.

In the figure, first, in order to reproduce the automatic performance data, one event data at a position indicated by a reproduction pointer secured at a predetermined position in the RAM 7 is read out (step S61). Is the note-on / off event data (step S62).

If it is determined in step S62 that the read event data is note-on / off event data, it is determined whether the note event data is for the guide track (channel 1 or 2) (step S62). Step S63).

If it is determined in step S63 that the read note event data is for a guide track, a matching progress process is performed according to the type of the event data (step S64). Specifically, when the read event data is note-on event data, the key code KC corresponding to the note-on event is written into the buffer 1 in FIG. In the case of data, the key code KC corresponding to the note-off event and the elapsed time data time (KC)
Remove.

In the following step S65, the buffer 1
After performing the keyboard color changing process of changing the key color of the reduced display keyboard 31 based on the data stored in the subroutine, as described with reference to FIG.

On the other hand, if it is determined in step S63 that the read note event data is not for the guide track, the MID corresponding to the event data is determined.
After outputting the I signal (code) (step S66),
The main reproduction processing subroutine ends.

On the other hand, if the read event data is not note-on / off event data in the determination in step S62, it is determined whether or not the event data is duration data (step S6).
7).

If it is determined in step S67 that the event data read is duration data, the value of the reproduction processing timer is updated by the following equation (step S67).
68) Thereafter, the main reproduction processing subroutine ends.

Reproduction processing timer = reproduction processing timer value +
Duration value × tempo coefficient value On the other hand, step S67
If the read event data is not duration data, it is determined whether or not the event data is tempo data (step S69).

If it is determined in step S69 that the read event data is tempo data, the tempo coefficient is changed according to the tempo data (step S7).
0) On the other hand, if the read event data is not tempo data, the present reproduction processing subroutine ends.

FIG. 10 is a flowchart showing a detailed procedure of the roll pre-setting processing subroutine of step S10 in FIG.

In the figure, first, in order to read data from the prefetch buffer, the read pointer secured at a predetermined position in the RAM 7 is advanced by "1", and the event data at the position indicated by the read pointer is read. One is read (step S81). Then, it is determined whether or not the read event data is note-on / off event data (step S82).

If it is determined in step S82 that the read event data is note-on / off event data, it is determined whether or not the data is note-on event data (step S83).

If it is determined in step S83 that the read note event data is note-on event data, it is determined according to the type of the data, that is, the black key /
It is determined whether the data is white key or right hand / left hand data, and the color of the scroll bar is set according to the result of the determination as described with reference to FIG. 3 (step S8).
4). Then, as will be described later with reference to FIG. 16, the scroll bar is drawn on the first and second lines of the scroll bar 32a in the area where the scroll bar is displayed (step S85), and the floor name / The pitch name is drawn (step S86).

On the other hand, if it is determined in step S83 that the read note event data is not note-on event data, ie, note-off event data, the drawing of the scroll bars on the first and second lines is deleted. (Step S87).

On the other hand, if it is determined in step S82 that the read event data is not note-on / off event data, it is determined whether or not the event data is bar line data (step S88). In this determination, if the read event data is bar line data, a bar line is drawn on the second line as described later with reference to FIG. 16 (step S89), while the read event data is Is not bar line data, that is, if the data is duration data, the value of the roll leading timer is updated by the following equation (step S9).
0).

Roll advance timer = roll advance timer value + duration value × tempo coefficient value Next, a predetermined number (N
The preceding data is read from the look-ahead buffer (step S91), and the lower limit value and the upper limit value of the key code of the note-on / off event data are searched out of the N pieces of data, and the lower limit value and the upper limit value are retrieved. It is determined whether or not the determined range is within the current enlarged display range (step S92). If it is not within the enlarged display range, a left / right scroll request for scrolling the enlarged display range left or right is made (step S).
93). Here, the left / right scroll request is specifically stored in a scroll request area secured at a predetermined position in the RAM 7 if a value corresponding to the direction and amount of the scroll request, for example, if the scroll direction is the left direction. Negative value (the absolute value indicates the scroll amount)
On the other hand, if the scrolling direction is the right direction, a positive value (the absolute value of which indicates the scroll amount) is stored.

On the other hand, if it is determined in step S92 that the range determined by the lower limit value and the upper limit value is within the current enlarged display range, step S93 is skipped and the process proceeds to step S94.

In step S94, it is determined whether or not data remains in the prefetch buffer. If no data remains, the prefetch processing subroutine described with reference to FIG. 7 is executed (step S95). If this remains, this roll pre-setting processing subroutine is immediately terminated.

FIG. 11 is a flowchart showing a detailed procedure of the scroll processing subroutine of step S12 in FIG.

In the figure, first, an initial value is set in the scroll timer (step S100).

Next, it is determined whether or not a pause is being made (step S101). Specifically, this determination is made by checking the state of the pause request flag FPAUSE.

If it is determined in step S101 that no pause is being made, that is, if FPAUSE = 0, the floor name /
Roll down the note name display area 32b (step S1).
02), only the floor name / note name is copied (step S10)
3) Roll down the scroll area 32a (step S104), and copy the top row (step S10).
5). Hereinafter, the processing of steps S102 to S105 will be described with reference to FIGS.

In FIG. 15, (a) shows a state in which the displayed note name “C” straddles the scroll area 32a and the floor name / note name display area 32b.
(A) is an enlarged view in which the vicinity of the boundary between the scroll area 32a and the floor name / note name display area 32b is enlarged and displayed;
(C) shows a state in which scrolling has progressed further than (a).

In (b), the dot D1 corresponds to the scroll area 32a among the dots displaying the note name "C".
The dot D2 indicates one dot in the floor name / note name display area 32b among the dots displaying the note name "C" (the dot is the minimum unit of drawing). Here, the floor name / note name is "white" when displayed in the scroll area 32a as described above.
And when it is displayed in the floor name / tone name display area 32b, it is displayed in "purple". Step S
The floor name / note name display area roll-down process 102 performs this process, and performs a process of changing the display color in addition to the roll-down process described later with reference to FIG.

In (c), scrolling proceeds from (a),
This shows a state in which all note names “C” have entered the floor name / note name display area 32b. Even if scrolling proceeds from this state, the note name “C” is displayed in the floor name / note name display area 32b.
Is not moved, and the state of (c) is continued. Then, at the same time when the scroll bar corresponding to the note name “C” disappears from the scroll area 32a, the display of the note name “C” also disappears. The process of copying only the note name in step S103 performs this processing. When the scrolling is advanced from the state of (c), the note name "C" is not moved in the floor name / note name display area 32b. A process of copying the note name "C" to the floor name / note name display area 32b and erasing the note name "C" at the same time that the scroll bar corresponding to the note name "C" disappears from the scroll area 32a.

FIG. 16A is a diagram showing a method of scrolling the scroll bar (ie, display from note-on to note-off) of FIG. 3 at 1 × speed, and FIG. 16B is a diagram showing the method of FIG. It is a figure which shows the method of scrolling a bar line (broken line) at 1x speed, (c) is a figure which shows the method of scrolling the scroll bar of (a) at 2x speed, (d) is (b) FIG. 8 is a diagram showing a method of scrolling a bar line at 2 × speed.

When the process of step S85 in FIG. 10 is performed, as shown in FIG. 10A, the dots D11 and D12 of the color determined by the process of step S84 are placed on the first and second lines of the scroll area 32a. Will be displayed.
Then, by the processing in step S104, the dot D11
And D12 are transferred to the third and fourth lines, respectively, and dots D11 'and D12' are displayed. In this way, the scroll bar RB1 is scrolled down once (2 dots) to become the scroll bar RB2. When the scroll bar RB2 is scrolled down once, the dots D11 'and D12' are transferred to the third and fourth lines, respectively, and the dots D11 "and D12" are displayed, and the dots D11 'and D12' are displayed. Is written with data of the dots D11 and D12. Next, note-off event data is read from the pre-read buffer, and in step S87,
When the drawing clear processing is performed, the background of the scroll area 32a is written in the first and second lines of the scroll area 32a, as indicated by the scroll bar RB4.
Then, similarly to the scroll bars RB2 and RB3, the scroll bars RB5 and RB6 are scrolled based on the data of the first and second rows.

As described above, the scroll bar is scrolled by moving the data displayed on the first and second lines to a position separated by a predetermined interval as it is. This is because we want to improve as much as possible. That is, in the present embodiment, scroll processing is performed in the main routine as described above, and no special hardware or the like is used, so that the time spent for scroll processing is limited. . On the other hand, in order to perform scrolling without using the above-described scrolling method, for example, it is necessary to add a process of searching for key-on event data, in particular, a note number, for each scroll. It gets longer.

The bar line is displayed as a horizontal line of one dot (line) (broken line as shown in FIG. 3) as shown in FIG. 3 (b). This is performed by writing two rows downward based on the data written in the first and second rows of the scroll area 32a (ie, in the case of a bar line, the data is written only in the second row).

In step S105, the top row, that is, the first row is copied to the second row. In a state where the scroll bar is displayed, the same color representing the scroll bar is displayed on the dots on the first and second lines. for that reason,
Even if the first line is copied to the second line, the state is the same as before and the scroll bar remains. However, while the bar line is displayed, the color of the bar line is displayed in the dots of the second row, but the scroll bar color or the background color is displayed in the dots of the first row. Therefore, if the first line is copied to the second line, the second line also becomes the scroll bar color or the background color. That is, when the process of step S105 is performed on the bar line, the portion where the bar line was previously displayed changes to the scroll bar color or the background color. Thus, step S85
If the scroll bar is drawn in step S10,
4. After passing through S105, the length is extended downward. However, when the bar line is drawn in step S85, the display position moves downward by passing through steps S104 and S105. Only. By the same processing, different processings of extending the scroll bar downward and moving the bar downward are realized. The process of extending the scroll bar in the downward direction is continued until the drawing of the scroll bar is cleared in step S87, and the background color is continued from the time when the drawing is cleared until the scroll bar is generated by the next key-on. .

(C) is different from (a) only in that scrolling is performed at double speed (every four lines). (D) is different from (b) in scrolling at double speed. The only difference is that scrolling is performed, and the other processing methods remain the same. The case of scrolling at double speed is shown because there is a lot of processing performed in the main routine, and when scrolling at 1 × speed may delay the display of the actual music, the display may start at 1 × speed. This is because the display can be switched to the double speed display. Therefore, when the processing speed of the CPU 5 is sufficiently fast and there is no delay in the display, only the 1 × speed scroll may be performed. The switching between the 1 × speed and the 2 × speed may be performed, for example, by inspecting the value of the scroll timer and according to the inspection result. More specifically, a process of detecting a value at which the scroll timer decreases when the main routine process is completed once is added to, for example, the other processes of the main routine of FIG. The flag is set / reset in step S104, and in step S104, the switching between the 1x speed and the 2x speed may be performed by checking the state of the flag.

In this embodiment, two lines are drawn at a time according to the event type in the roll pre-setting process (when there is a key-on, the color of the scroll bar is used for both lines, and when there is a key-off, two lines are drawn). The background color of each line, if there is a bar line, only the second line is the bar color), scroll down the second line in the scrolling process, and copy the top line to the second line. , Scrolling is realized, but the number of lines to be drawn and scrolled can be changed as appropriate. For example, in the roll prepositioning process, three lines are drawn at a time according to the event type (when there is a key-on, the scroll bar color for all three lines, and when there is a key-off, the background color and bar lines for all three lines). At the time, the first line and the second line are scroll bar colors or background colors, the third line is a bar line color), and after scrolling down three lines in the scrolling process, the first line and the second line are changed to the second line. Scrolling may be realized by copying the third and third lines.
Also, the bar line color is changed to 2 in the first line by the bar line event.
The same processing is performed by drawing the scroll bar color or the background color on the line and copying the second line to the first line in the scroll processing. In short, the color display of the scroll bar always exists in the first few lines from key-on to key-off, and the background color always exists in the first few lines from key-off to key-on. In the first few lines, part of the bar line color is the bar color and the rest is the scroll bar color or background color, so that the bar line color is rewritten to the scroll bar color or background color in the scrolling process. The number of lines can be selected and the way of copying is free.

Returning to FIG. 11, when the pause is determined in the determination in step S101, that is, when FPAUSE = 1, the flow advances to step S106 to count the number of times this scroll processing subroutine is called.
It is determined whether the value of the soft counter M secured at a predetermined position of M7 is equal to the set value k. By this determination, M ≠ k
In this case, after the counter M is incremented by "1" (step S107), the scroll processing subroutine ends. On the other hand, in the determination of step S106,
If M = k, the counter M is reset (M = 0) (step S108), and the value of the scroll request area is inspected to determine whether there is a scroll request (step S109).

If it is determined in step S109 that the value of the scroll request area (request value) is not "0", that is, if a scroll request has been made, it is determined whether the request value is positive or negative ( Step S110). In this determination, when the request value is positive (> 0), the enlarged display area is scrolled to the right by a moving amount corresponding to the request value (step S111), while the request value is negative (<0).
In the case of, the enlarged display area is scrolled to the left by a moving amount corresponding to the absolute value of the request value (step S112).

If the amount of left and right scrolling is large, it takes a long time to perform one moving process. Therefore, the moving may be performed several times (for example, only one white key at a time). This also has the effect that the enlarged display area gradually moves to make it easier to see.

On the other hand, if it is determined in step S109 that the request value is "0", the scroll processing subroutine is immediately terminated.

FIG. 12 is a flowchart showing a detailed procedure of the key processing subroutine of step S14 in FIG.

In the figure, first, a coincidence progress processing corresponding to key depression or key release is performed (step S121). Specifically, when a key is pressed, a key code K corresponding to the key is pressed.
C is written into the buffer 2 of FIG. 14, and when the key is released, the key code KC corresponding to the key release is deleted from the buffer 2.

Next, in the same manner as in step S65 of FIG. 9, a keyboard color changing process is performed based on the data stored in the buffer 2 (step S122), and it is determined whether or not the pause state has been released (step S122). Step S123). Here, whether or not the pause state has been released is determined by comparing the contents of the buffers 1 and 2 and determining whether or not there is a key press on the automatic performance data that caused the pause state.

When the pause state is released in step S123, for example, the pause request flag FPAU
Pause release processing such as resetting of the SE ("0") is performed (step S124), and when not in the pause state or when the pause state is not released, the key processing subroutine ends.

FIG. 13 is a flowchart showing the procedure of a timer interrupt process. This timer interrupt process is executed in response to an interrupt signal generated from the timer 8 to the CPU 5 every 10 msec.

In the figure, first, the coincidence progress timer is incremented by "1" (step S13).
1).

Next, the pause request flag FPAUSE is set.
(Step S132), the timer interrupt processing is immediately terminated when the pause request flag FPAUSE = 1, that is, when the pause is being performed, while when the pause request flag FPAUSE = 0, and when the pause is not being performed, the step S133 is performed. Proceed to.

In step S133, the reproduction processing timer is decremented by "1". In step S134, the roll leading timer is decremented by "1". In step S135, the scroll timer is decremented by "1".
After decrementing only by one, the timer interrupt processing ends.

Although the timer interrupt process actually performs various other processes, it is not an essential process for explaining the present invention, and a description thereof will be omitted.

FIG. 17 is a diagram showing another example of the display displayed on the display device 9. In FIG.

FIG. 3 divides the scroll area 32a of the piano roll paper 32 equally into the number of white keys, whereas FIG. 17 divides the scroll area 32a into the number of all keys (white keys and black keys). The main difference is that they are equally divided into two. Further, the display example of FIG. 17 is different from the display example of FIG. 17 in that the width of the scroll bar is changed according to the magnitude of the velocity of the note event data, as indicated by the scroll bar of the note name B. Also in FIG. 3, the width of the scroll bar may be changed according to the magnitude of the velocity.

In FIG. 17, the width of the scroll bar is larger than the width of the vertical line of the scroll area. However, the width of the scroll bar is set to be smaller than the width of the vertical line. Alternatively, the change control may be performed.

Further, also in FIGS. 3 and 17, the width of the divided area (the area where each scroll bar scrolls) is set to be the same width everywhere in the vertical direction of the scroll area 32a. Not limited to this, the width may be narrower as going upward. This way,
The part close in time is displayed large (thick), and the part that must be played next is emphasized. Conversely, the width may increase as it goes upward. Furthermore, in the present embodiment, the reduced display keyboard 31 is displayed at the lower portion of the screen of the display device 9, the scroll area 32a is displayed at the upper portion, and the scroll bar is scrolled from top to bottom. Conversely, the reduced display keyboard 31 may be displayed at the upper portion of the screen of the display device 9, the scroll area 32a may be displayed at the lower portion, and the scroll bar may be scrolled from bottom to top.

As described above, in the present embodiment,

Since 32 is scrolled, even a beginner who cannot read the staff can easily recognize the position of the key to be operated.

Since the time length from key-on to key-off is indicated by the length of the scroll bar, the key-off timing can be easily grasped.

Further, since the piano roll paper 32 displays all the keys from the current operation state to a future operation state within a predetermined range at a time, the progress of the music can be read ahead.

Furthermore, since the color of the scroll bar is changed according to the left / right hand data and the floor name is displayed below the scroll bar, the visibility of the key operation can be improved. Thereby, a high performance assisting effect can be obtained.

Further, since the color of the keys on the keyboard is changed according to the correctness of the key pressed by the player, the performance can be fed back and the practice effect can be improved.

In the present embodiment, the width of the scroll bar is constant regardless of the type of data. However, the present invention is not limited to this, and the width and color of the scroll bar may vary depending on the value of velocity data in the note event data. May be changed. As a result, it is possible to express a musical idea that was difficult with the conventional keyboard LED.

Further, on the reduced display keyboard 31, a model model of a hand (for example, image data or a line drawing of a teacher's hand) may be displayed. At this time, the position of the player's hand may be detected and displayed together on the reduced display keyboard 31. Here, to detect the position of the player's hand, a contact sensor is provided on the keyboard 1 to detect a key touched by the player's hand, or a capacitance sensor or an optical sensor is provided to detect a key approached by the hand. What is necessary is just to detect.

In this embodiment, the tempo is changed as described in steps S68 to S70 in FIG.
Although the tempo coefficient was changed and the value of the timing data was corrected by this, the present invention is not limited to this. The period of the tempo clock may be changed, and the value for counting the timing data in one process may be used. (Count amount) may be changed.

Further, in the present embodiment, after data is stored in the pre-read buffer, data is read from this buffer and various processes are performed. However, the present invention is not limited to this.
When the capacity of PU5 is high, the RA
Data to be pre-read may be read from the music data storage area of M7, and various processes may be performed accordingly.

In the present embodiment, the note name is displayed in alphabets near the scroll bar. However, the present invention is not limited to this.
"", "", Etc.). Further, a finger number (numerical value or nomination) may be displayed instead of or in addition to the floor name or the note name.

Also, a model performance using automatic performance data,
The result of the performance performed by the player may be superimposed and displayed on the piano roll paper 32 to indicate the difference between the two. At this time, for example, at the time of the first reproduction, the player performs a performance input (hand-play input) while watching the model performance based on the automatic performance data, and at the time of the second reproduction, the model performance and the hand-play performance are superimposed and displayed. You may do so.

In the present embodiment, an actual physical keyboard is used as the keyboard 1, but a touch panel is provided on the screen of the display device 5 without using the keyboard 1, and the reduced display keyboard 3 is provided.
The match may be made to proceed by directly touching the key on 1.

In the present embodiment, the present invention is configured in the form of an electronic keyboard instrument, but is not limited thereto, and may be configured in the form of a personal computer and an application program. Further, the present invention can be applied to a device such as a karaoke device.
