FIG. 2 is a schematic diagram showing an outline of a computer system in which the present invention is implemented. The computer system includes a CPU 1, a CRT 2, a keyboard 3 for inputting data, and a mouse 4.

The contents of the present invention are stored in a floppy disk as a program and supplied to the CPU 1. Keyboard 5 indicates which key has been depressed,
It detects whether the depressed key has been released and the key release speed and outputs it as a MIDI signal. CPU1
Can input this MIDI signal and display it as a musical score, and can also set notes one by one by operating the keyboard 3 or the mouse 4 and display it as a musical score. To generate a MIDI signal. Note that display information for displaying a score on the CRT 2 is stored in a memory (not shown) provided in the CPU 1.

A sound source 6 is connected to the CPU 1.
1 supplies a MIDI signal input from the keyboard 5 or a MIDI signal created based on a displayed musical score to a sound source 6. The sound source 6 receives the MIDI signal, generates a corresponding tone signal, and outputs the signal to the outside via the amplifier 7 and the speaker 8.

FIG. 3 shows an example of a staff frame displayed on the display screen of the musical score display means 12. As shown in FIG. In a normal printed score, the staves of each part where the performance progresses simultaneously are displayed collectively as a group of staves for several measures. A staff frame is displayed in units of a staff group obtained by integrating measures. This staff frame is displayed based on display information from the CPU 1. In this staff frame, two part areas 24 and 26 of the staff are displayed. Part upper limit line 2 indicating the upper limit position of part area 24
8. Part boundary line 3 indicating the boundary between the part areas 24 and 26
Each of the part areas 24 and 26 is determined by a part lower limit line 30 indicating 0, the lower limit of the part area 26. In these part areas 24 and 26, staff notation areas 34 and 36 are displayed, respectively. Also, bar boundaries 38, 38... Indicating boundaries of bars in the staff notation areas 34, 36 are displayed. In addition, 40, 40
.. Are grids indicating the positions at which musical notes are displayed in each bar. The staff frame of FIG. 3 is a so-called one-staff in which one staff is represented by one staff, but when the number of parts to be played simultaneously is two, one staff is represented by two staffs. It may be a so-called two-stage musical notation in which parts are represented.

In FIG. 3, on the left side of each of the parts 24 and 26, part selection operators 42 and 44 are displayed at intervals from the parts 24 and 26 so as to correspond to these parts, respectively. Also, these part selection operators 42 and 44
The part boundary change operator 50 is displayed in between. Further, staff notation area change operators 46 and 48 are displayed so as to correspond to the staff notation areas 34 and 36 in the parts 24 and 26, respectively.

On the upper side of the part area 24, bar selection operators 52, 52... Are displayed at intervals from the part area 24 so as to correspond to the area of each bar. .. Are displayed between the measure selecting operators 52, 52..., That is, at positions corresponding to the bar boundary lines 38, 38. . Further, a staff frame selection operator 56 is also displayed at the left end corner of the staff frame.

The staff notation area change operators 46 and 48, the part boundary change operator 50, and the bar boundary change operator 54 are designated by the mouse 4, and what is to be changed is designated. If you specify a location,
Move to that movement position.

For example, by specifying the part boundary change operator 50 with the mouse 4, the part boundary line 30 is substantially specified, and then the part boundary line 3 is specified by the mouse 4.
When a new position of 0 is designated, the part boundary line 30 moves to the new position.

Further, when the staff notation area change operator 46 is designated by the mouse 4 to substantially designate the staff notation area 34, and then the mouse 4 designates a new moving position of the staff notation area 34, the new position Is moved to the staff notation area 34.

Further, the bar boundary changing line 54 of the first and second bars is substantially designated by designating the bar boundary changing operator 54 at the boundary position of the first and second bars with the mouse 4. When a new position of the bar boundary 38 of the first and second measures is specified by the mouse 4 and then, the boundary line 38 of the first and second measures is moved to that position.

In order to perform such control, the CPU 1 operates as shown in FIG. That is, first, mouse 4
The state of the two buttons provided in 16 is fetched (step S2), and it is determined whether the left button of these buttons is pressed (step S4). If the button has been pressed, processing relating to the mouse 4 is performed (step S6). Subsequent to this processing or when it is determined in step S4 that the button has not been pressed, the processing of the keyboard 3 provided in the CPU 1 is performed (step S4).
8). When step S8 is completed, step S8 is performed again.
Execute 2.

The processing relating to the mouse 4 is performed, for example, as shown in FIG. That is, first, the coordinate position on the screen where the left button of the mouse 4 is pressed is acquired (step S1).
0). The acquisition of the position in step S10 corresponds to the position acquisition unit 18 shown in FIG. The acquired coordinates are the bar boundary changing operator 54 (step S12), the part boundary changing operator 50 (step S14), and the staff notation area changing operators 46 and 48 (step S14). S16) is determined.

If it is the bar boundary changing operator 54, the bar boundary changing process is performed (step S18), and if it is the part boundary changing operator 50, the part boundary changing process is performed (step S20), and the staff area is changed. If it is an operator, a staff notation area change process is performed (step S22). Steps S12, S14, and S16 function as execution assignment means, and steps S18, S20, and S22 correspond to the display control means 22 shown in FIG.

In the bar boundary changing process in step S18, as shown in FIG. 6, first, among the coordinates designated by the mouse 4, the X coordinate (the horizontal coordinate in FIG. 3) is acquired as curX (step S24). . Note that the value of the X coordinate becomes larger as going from the left side to the right side in FIG.

Next, whether the acquired value of curX is smaller than minX which is the minimum X coordinate that can be taken by the bar boundary changing operator 54 previously specified in step S10, that is, the minimum X coordinate minX Is also determined as a value representing the left side (step S26). If the minimum X coordinate m
If the value is smaller than inX, the bar boundary 38 cannot be moved to that position. Therefore, curX is added to the minimum X coordinate minX that can be moved to the left.
Is changed (step S28).

If the value of curX is greater than minX,
Next, it is determined whether the value of curX is larger than the maximum X coordinate maxX that can be taken by the staff frame, that is, a value representing the right side of the maximum X coordinate maxX (step S30). If the value is larger than the maximum X coordinate maxX, the bar boundary change line 38 cannot be moved to that position, so the value of curX is changed to the maximum X coordinate maxX that can be moved to the right. (Step S32).

In step S30, the value of curX is m
If it is determined that it is smaller than inX, step S28
Is executed, or after executing step S32, it is determined whether the left button of the mouse 4 is kept pressed (step S34). If the button is kept pressed, the process returns to step S24 because the new movement position of the bar boundary 38 has not been determined yet.

If the button of the mouse 4 is depressed, a new movement position of the bar boundary 38 has been determined, so that a bar size changing process is performed (step S36). That is, the coordinates of the bar boundary 38 whose position is to be changed are set to the value of curX, and accordingly, the coordinates of other screen elements, for example, the grid 40 are also changed. Then, the screen is redrawn based on the changed coordinates,
The bar boundary change processing ends.

In the part boundary changing process, as shown in FIG. 7, first, the Y coordinate (the vertical coordinate of the screen) designated by the mouse 4 is acquired as curY (step S40).
The Y coordinate increases from the top to the bottom of the screen.

If the value of curY thus obtained is smaller than the minimum Y coordinate minY, that is, if the part boundary line 30
Is smaller than the value of the position that does not invade the upper staff area 34 (step S42). If smaller, the value of curY is set to minY (step S4).
4).

If the value of curY is larger than minY, it is determined whether the value of curY is larger than the maximum Y coordinate maxY, that is, larger than the value of a position not affecting the lower staff notation area 36 (step S46). ). If cu
If the value of rY is larger than maxY, the value of curY is set to maxY (step S48).

In step S46, the value of curY is maxY.
If it is smaller than the above, if step S44 has been executed, or if step S48 has been executed, subsequently, it is determined whether or not the left button of the mouse 4 has been pressed (step S50).

If the button is kept pressed, the process returns to step S40 because the position of the new part boundary line 30 has not been determined yet. If the left button of the mouse 4 has not been pressed, the position of the new part boundary line 30 has been determined, and the redrawing process is performed using the value of curY as the coordinate position of the new part boundary line 30 (step). S52).
Thus, the part boundary change processing ends.

In the staff notation area changing process, as shown in FIG. 8, first, the Y coordinate acquired by curY by the pointing device 16 is the staff notation changing operator in the two-staff, as shown in FIG. It is determined whether such a staff notation area change operator 46 or 48 is a single staff (step S5).
4). If it is a double staff, it is determined whether or not it is the staff notation area change operator 46a in the upper row as shown in FIG. 9B (step S56).

In the case of the staff notation area change operator 46a in the upper row, the current upper end of the staff notation area change operator 46a is determined based on the value of curY at that time (Y coordinate of the upper end of the new staff notation area change operator 46a). Subtract the Y coordinate utY,
The shift between the position currently designated by the mouse 4 and the Y coordinate utY is calculated and stored in offsY (step S5).
8).

Then, the position (cursor position) designated by the mouse 4 is acquired (step S60), and whether the Y coordinate of this acquired position and the value of curY have changed, that is, the position designated by the mouse 4 It is determined whether is moving (step S62).

If there is no change, it means that a new staff notation area has not been determined yet, so the process proceeds to step S76.
It is determined whether or not the button has been released. If the button has not been released, the process returns to step S54. If the button has been released, the process of step S78 is executed, and the current coordinates curY and H
Redraw processing is performed based on the value of. If there is a change, the Y coordinate acquired in step S60 is stored in curY (step S64). Furthermore, from this curY to offsY
Is subtracted, and the current position of the upper end of the staff notation change operator 46a, which is viewed with reference to the Y coordinate of the upper end of the staff notation area change operator 46a obtained in step S58, is stored in curY (step S66).

Then, it is determined whether or not the value obtained by adding the width H of the staff notation area changing operator 46a to the value of curY is smaller than the value of the Y coordinate ltY at the upper end of the staff notation changing area operator 48a at the lower stage ( Step S68). If it is larger, the lower end of the upper staff area changing operator 46a will overlap the lower staff area changing operator 48a, so the value obtained by subtracting H from ltY is set as the value of curY (step S70).

If the value obtained by adding H to the value of curY is Y
If it is smaller than the value of the coordinate ltY, or step S7
After 0, it is determined whether the value of curY is larger than the Y coordinate ptY at the upper end of the part area (step S72).

If it is large, the staff notation area change operator 4
6a is positioned above the upper end of the part area and cannot be displayed.
(Step S74).

If the value of curY is smaller than the Y coordinate ptY at the upper end of the part area, the upper end of the staff notation area change operator 46a can be displayed as it is, so that the left button of the pointing device 16 is released. A determination is made (step S76). After the execution of step S74, since the upper end of the staff notation area change operation element 46a can be displayed, step S76 is executed.

If the left button has not been released in step S76, the final position of the staff notation area change operation element 46a has not been determined yet, so step S54.
Return to If it is released, the staff notation area change operator 4
Since the final position of 6a is determined, redrawing processing is performed based on the values of curY and H so as to display the position of the staff notation area corresponding to the staff notation area change operator 46a (step). S78).

In step S56, if it is determined that the notation is not the upper staff notation change operator 46a, the current staff value change operation (the Y coordinate of the upper end of the new staff notation change operator 48a) is used to determine this staff notation change operation. The difference between the position currently designated by the mouse 4 and the Y coordinate ltY is calculated by subtracting the Y coordinate ltY of the current upper end of the child 48a, and o
ffsY (step S80).

Then, the position (cursor position) designated by the mouse 4 is acquired (step S82), and there is a change between the Y coordinate of this acquired position and the value of curY, that is, the position designated by the mouse 4. It is determined whether is moving (step S84).

If there is no change, since a new staff area has not yet been determined, the flow advances to step S76 to determine whether or not the button has been released. If not, the flow returns to step S54 to return to step S54. If so, the processing of step S78 is executed, and the redrawing processing is performed based on the current values of curY and H. If there is a change, step S82
Is stored in curY (step S)
86). Further, offsY is subtracted from this curY, and the staff notation area change operator 48 obtained in step S80 is obtained.
The current position of the upper end of the staff change operator 48a, which is viewed with reference to the Y coordinate of the upper end of a, is stored in curY (step S88).

Then, it is determined whether the value obtained by adding the width H of the staff notation area change operator 48a to the value of curY is smaller than the value of the Y coordinate pbY at the lower end of the part display area shown in FIG. 9B. (Step S90). If big,
Since the lower end of the staff notation area change operator 48a is located below the lower end of the part display area, the value obtained by subtracting H from pbY is set as the value of curY (step S9).
2).

If the value obtained by adding H to the value of curY is Y
If smaller than the value of the coordinate pbY, or step S9
Subsequent to 2, it is determined whether the value of curY is larger than the Y coordinate ubY at the lower end of the upper staff notation area change operator 46a (step S94).

If it is larger, the staff notation change operator 4
Since the upper end of 8a overlaps the upper staff notation area change operator 46a, ubY is set to the value of curY (step S96). Then, in step S94, curY
Is lower than Y at the lower end of the upper staff notation area change operator 46a.
If the coordinates are larger than ubY, the staff notation area change operator 48
Since the upper end of a does not overlap with the staff notation area change operator 46a in the upper row, step S76 is executed. Step S9
When step 6 is executed, there is no overlap.
Execute

If it is determined in step S54 that the current score is a one-staff, the curation from which the Y coordinate is acquired among the coordinates designated by the mouse 4 at that time is changed from the staff notation area designated at that time. By subtracting the Y coordinate utY at the upper end of the operation element, for example, 46, the deviation between the position currently designated by the mouse 4 and the Y coordinate ltY is calculated, and this is turned off.
It is stored in sY (step S98).

Then, the position (cursor position) designated by the mouse 4 is acquired (step S100), and whether the Y coordinate of this acquired position and the value of curY change, that is, the position designated by the mouse 4 It is determined whether is moving (step S102).

If there is no change, a new staff notation area has not been determined yet, so the process proceeds to step S76.
It is determined whether or not the button has been released. If the button has not been released, the process returns to step S54. If the button has been released, the process of step S78 is executed, and the current coordinates curY and H
Redraw processing is performed based on the value of. If there is a change, the Y coordinate acquired in step S100 is stored in curY (step S104). Furthermore, from this curY, of
The value of fsY is subtracted, and the position of the upper end of the staff notation change operator 46 this time, which is viewed with reference to the Y coordinate of the upper end of the staff notation area change operator 46 obtained in step S98, is stored in curY (step S106).

Then, it is determined whether the value obtained by adding the width H of the staff notation area change operator 46 to the value of curY is smaller than the value of the Y coordinate pbY at the lower end of the part display area shown in FIG. 9A. (Step S108). If big,
Since the lower end of the staff notation area change operator 46 is located below the lower end of the part display area, a value obtained by subtracting H from pbY is set as the value of curY (step S11).
0).

If the value obtained by adding H to the value of curY is Y
If smaller than the value of the coordinate pbY, or step S9
After step 2, step S72 is executed.

As described above, in this embodiment, the boundaries of each bar, the boundaries of the part areas, and the staff notation area can be changed. Further, the part selection operator 4 shown in FIG.
The following editing can also be performed by designating the 2, 44, bar selection operator 52, and staff frame selection operator 56 with the mouse 4.

For example, when an arbitrary one of the bar selecting operators 52 is designated by the mouse 4, the bars of all parts corresponding to the specified bar selecting operator 52 are selected. Such selections include deleting, copying, moving, and transposing measures in all selected parts, increasing or decreasing the volume (crescendo, decrescendo), changing the tempo, Change the tempo in the beginning (Accherand, Ritaldando, A Tempo,
This is effective when the gate time is collectively changed at an arbitrary ratio, for example, shortened or lengthened by several percent (staccato, marcato, tenuto).

Similarly, when one of the part selection operators 42 and 44 is designated by the mouse 4, the designated part is selected. This selection allows you to delete, copy, move, transpose, and increase or decrease the volume (crescendo,
(Decrescendo), changing the tempo, changing the tempo in the beginning (Accherand, Ritaldando, a tempo, stringent), changing the gate time at an arbitrary rate in a lump, for example, shortening by several percent It is effective when lengthening (Staccato, Marca Tissimo).

When the staff frame selection operator 56 is designated by the mouse 4, the entire staff frame is selected. This selection allows you to delete, copy, or move only the selected staff frame, increase the volume, change the tempo, change the tempo in the first order, and adjust the sounding timing all at once. This is effective when changing at an arbitrary ratio, for example, shortening or lengthening by several percent.

In the above embodiment, the minimum Y coordinate minY that the part boundary change operator 50 can take is set to a coordinate position that does not violate the staff notation area.
Of the upper end of the staff notation change operator 46 as the change position of
When the mouse 4 specifies a position beyond the coordinate utY, the part area corresponding to the part boundary change operator 50, for example, is set to a non-display attribute that does not display 24, and the lower part area, for example, 26 is set to the part area 24. May be displayed at the position where it was originally displayed. By doing so, it is possible to display only the parts actually played without displaying the staff notation in the part area that follows the rest, thereby making it easier to read the score.

[0056]

As described above, according to the present invention, the boundary position of each bar can be arbitrarily changed, so that a large number of notes are displayed in a certain bar, and conversely, a very small number of notes are displayed. And so on. Furthermore, the boundaries of each part area can be changed, and the display position of the staff notation area within the part can be changed, so that it is significantly lower than the first line of the staff or significantly higher than the fifth line. If it is necessary to display a note, it can be dealt with.
