2. Description of the Related Art Conventionally, there has been known a display / editing apparatus which displays automatic performance data and edits (inserts, adds, deletes, corrects, etc.) the automatic performance data by performing a predetermined operation by a user. . Automatic performance data for one song is usually divided into units such as tracks or parts. Hereinafter, the term “track” includes the concept of an arbitrary unit divided by another method such as a part. The automatic performance data of each track includes, for example, a note event (for example, including information such as a timing of generating a musical tone, pitch and note length) or various control events (for example, program change). These are arranged in order of occurrence time. Automatic performance is performed by reading out automatic performance data and generating musical tones in accordance with the automatic performance data.

Conventionally, when editing such automatic performance data, all event data of a plurality of tracks in one piece of automatic performance data are usually mixed and displayed. As the display format, a list format or a piano roll format has been used. The list format is a format in which event data is arranged and displayed in the order of occurrence of events. In the case of the list format, there is a type that performs color coding according to the type of event at the time of display. The piano roll format is a rectangular form of a note event on two-dimensional coordinates where the pitch of the note event is taken in one direction and the time of the note event is taken in the other direction (the length in the time axis direction corresponds to the note length). Format). The rectangle corresponding to the note event is displayed in a different color for each track. The user can edit desired event data by performing a predetermined operation while referring to this display.

[0004]

In the above-described conventional automatic performance data display / editing device, the event data of all tracks is displayed in a list, so that events appearing in the same bar can be seen at a glance. It is convenient. However, on the other hand, there is a problem that the entire display screen becomes complicated. In particular, in the piano roll format,
There are cases where rectangles corresponding to note events overlap, and there is a problem that there are note events that are difficult to see or that are invisible due to overlap. In addition, since the event data of all the tracks is displayed in the same manner, when inputting a new event, it is difficult to know which track the event is input. Further, when editing an event that has already been input, there is a possibility that an event of a track other than the target track is erroneously edited.

FIG. 2 shows the structure of the automatic performance data of one music to be displayed and edited. The automatic performance data includes several pointer lists and event data in an event data storage area. The top-level pointer list 200 includes
Blocks constituting the automatic performance data are described. This may be a name specifying a block or a pointer to a pointer list 210 to 230 of each block. 210, 220, and 230 are pointer lists of blocks 1, 2, and 3, respectively. The pointer lists 210 to 230 of each block are lists in which pointers indicating addresses of event data scattered in the event data storage area 240 are arranged in the order of event occurrence time. For example, the pointer list 230 of the block 3 includes pointers P3-1 to P3-n, and each of these pointers points to event data in the event data storage area 240. As a result, when reproducing the data of the block 3, first, an event of the event data 2 indicated by the pointer P3-1 is generated, and then the pointer P3-1 is generated.
An event of event data 5 indicated by 3-2 is generated, and ...
Thus, automatic performance is performed.

One event data stored in the event data storage area 240 is composed of track block data + Δt + event type + various values. The track block data is an identifier for identifying a track and a block to which the event belongs. Δt indicates a relative time from the end of the previous event in the block to the occurrence of the event. Note that Δt of the event at the head of the block is a relative time from the start of the block. It is assumed that the start time of each block is held as accompanying information of each block in the highest-order pointer list 200. Note that the start time of each block is not limited to the one stored in the pointer list 200 and may be stored in the pointer list 210 to 230 of each block. The event type indicates an event format such as a note event or various control events. The various values are parameter values of the event, and for example, in the case of a note event, indicate values such as a note number (pitch), a gate time (note length), and a velocity (sound strength). In the pointer lists 210 to 230 of the respective blocks, pointers are arranged so as to point to event data that occurs in chronological order. Therefore, each event data in the event data storage area 240 may be scattered in this area 240.

FIG. 2B is a conceptual diagram of such automatic performance data for one music piece. The automatic performance data 250 conceptually includes a plurality of tracks. Each track corresponds to one MIDI channel, and can set different tone colors. In each track, blocks, which are performance data in small units, are arranged as shown in 251. FIG.
In (b), the blocks arranged on each track are arranged in time order (the horizontal direction in the figure is the time axis). A plurality of blocks may temporally overlap in one track. In the example of FIG. 2A, the identifier of the track that includes the event data is stored in the event data that arrives at the pointer list. Information on which block is included may be held.

FIG. 3 shows an example of a display screen when the automatic performance data shown in FIG. 2 is displayed and edited by the apparatus shown in FIG. In this apparatus, a conventionally known window system operates, and automatic performance data of one music to be displayed and edited is displayed in one window 300. The window 300 includes an event display area 301 for displaying event data in a list format. On the right side of the event display area 301, a scroll bar 302 for scrolling the display screen of the event display area 301 up and down.
Is provided. Below the event display area 301, a scroll bar 303 for scrolling the display screen of the event display area 301 right and left is provided. By operating these scroll bars 302 and 303, any event data of the automatic performance data to be displayed and edited can be displayed.

In the event data list display in the event display area 301, each row indicates one event data. The meaning of each field of the event data will be described.

Reference numeral 311 denotes a block number of a block including the event. Numerals 312 to 314 indicate data indicating the time position at which the event occurs, 312 indicates a bar, 313 indicates a beat, and 314 indicates an intra-beat timing. For example, the event data 325 in the top row of the event display area 301 indicates an event belonging to a block having a block number of 2 and an event occurring at a position where the intra-beat timing of the third beat in the twentieth bar is 360. Is shown. In the intra-beat timing, one beat is equally divided into 480 small sections, and positions are indicated by numbers 0 to 479 attached to each small section.
In FIG. 3, the event data existing from the twentieth bar to the middle of the twenty-first bar is displayed.

Reference numeral 315 indicates the event type of the event. As the event type, a note event instructing the generation of a musical tone (in FIG. 3, the event type is “Not
e)) and various control events (such as a program change instructing a change in tone). 3
16 to 318 indicate event values which are parameters of the event. In particular, when the event type is a note event, the event value 316 is the note number (pitch) of the tone to be emitted, the event value 317 is the gate time (note length) of the tone to be emitted, and the event value 318 is the strength of the tone to be emitted. (Velocity). As the event value 316 indicating the note number, a note name (“G2”, “D # 2” or the like) and an actual numerical value (a value in []) are displayed. As the event value 317 indicating the gate time, a note display and an actual numerical value (a value in []) are displayed. This number is 4 beats per beat
The period from the start of the event (indicated by the above-mentioned reference numerals 312 to 314) to the sound ending position is represented in units of small sections equally divided into 80. The value before [:] in [] represents the number of beats, and the value after: represents the number of the unit in one beat. As the event value 318 indicating the strength, a strength symbol (“f
f ”and“ fff ”) and actual numerical values (values in []) are displayed.

Reference numeral 304 denotes an editable block. FIG.
Now, since "Block1" is displayed,
It can be seen that the block whose block number is 1 can be edited. By inputting a block number in this area 304, or by clicking a downward pointing triangle on the right side of this area with a mouse and selecting one from a list of blocks displayed, the editable block can be switched.

The event data belonging to the editable block is highlighted in the event display area 301. Event data belonging to other non-editable blocks are displayed in the event display area 301 without emphasis. For example, in FIG. 3, since the block with the block number 1 is an editable block, the event data 321 to 324 belonging to the block with the block number 1 are highlighted with hatching. The other blocks are non-editable blocks and are therefore displayed without emphasis. The method of highlighting is not limited to shading, and various methods such as bold display, changing colors, changing the size and format of characters (such as italics), adding an underline, and inverting display are used. May be.

In FIG. 3, when the mouse pointer is placed on the event data of the editable block which is highlighted and clicked, the event data is selected and highlighted. In this state, by inputting a predetermined key from the typing keyboard 109, the event data can be edited. Specifically, the value of each field 311 to 318 of the event data can be changed, the event data can be deleted, and new event data can be inserted immediately before the event data. In FIG. 3, if the mouse pointer is clicked on the event data that is not highlighted, a warning message indicating that the event data cannot be edited is displayed, and the event data cannot be edited.

Next, the procedure for displaying the list of the automatic performance data described in FIG. 3 and editing the data on the display screen will be described. First, it is assumed that the user instructs display and editing of automatic performance data by an operation (not shown) (menu selection or predetermined key operation). At this time, the automatic performance data to be edited is specified by the user.

FIG. 4 shows a procedure of a list display processing routine executed when display and editing of automatic performance data is instructed. In step 401, one or more blocks to be displayed are selected from the blocks included in the automatic performance data to be displayed. This selection operation is performed by a predetermined operation such as menu selection. Instead of allowing the user to select a block to be displayed, all blocks of the specified automatic performance data may be displayed. Next, in step 402, a block to be edited (referred to as an editable block) is designated. This specification may be performed by the user in the same manner as the selection of the display block in step 401, or a predetermined block may be set as an editable block at first (for example, the first block 1 may be specified or the editable block may be specified). (No block).

In step 403, pointers included in one or more blocks selected as blocks to be displayed in step 401 are sorted in chronological order. FIG.
FIG. 2C shows an example 260 in which the pointers of the respective blocks of the automatic performance data of FIG. In this sorting, the occurrence time of all event data is obtained by tracing the pointer of each block to be displayed, and in the order of the occurrence time,
This is the process of arranging the corresponding pointers. Note that, as described with reference to FIG. 2, the actual event data does not hold the occurrence time of the event data. Instead, the actual event data waits for the completion of the previous event in the block. Is provided before the occurrence of the relative time Δt.
Therefore, the occurrence time of each event data is calculated by sequentially accumulating the relative time Δt. At this time, since data of 312 to 314 indicating the generation time of the event data described with reference to FIG. 3 is obtained, the data is held in a predetermined work area for use in later display.

Next, in step 404, the event data pointed to by the first pointer of the sorting result (260 in FIG. 2C) is referred to. In step 405, it is determined whether or not the referenced event is event data of an editable block. If it is the event data of the editable block, various values based on the event data are highlighted in step 406 (for example, 321 to 324 in FIG. 3).
If it is determined in step 405 that the event data is not the event data of the editable block, various values based on the event data are non-highlighted in step 407 (for example, 32 in FIG. 3).
5). After steps 406 and 407, step 408
To determine whether the processing is completed, that is, the sort result (2 in FIG. 2C).
It is determined whether or not the processing up to the final data of 60) has been performed. If unprocessed data remains, the event data pointed to by the next pointer is referred to in step 409, and the process returns to step 405 and repeats from the process of determining whether or not the block is an editable block. In step 408, the sorting result (26 in FIG.
When the processing has been performed up to the final data of 0), the list display processing ends. In step 408, it is determined whether the process has been performed (displayed) up to the final data. However, when there is much display data, not all data can be displayed in the window 300. The control of which range of the entire display data is displayed in the window 300 is performed by the window system. With the above processing, a display as shown in FIG. 3 is made.

Next, a procedure for editing the automatic performance data on the display screen as shown in FIG. 3 will be described.

FIG. 5 shows the procedure of an editing routine for editing automatic performance data. In step 501, the user specifies an event position to be edited on the screen of FIG. 3 using the mouse 110 or the cursor movement key of the typing keyboard 109. In step 502, a pointer corresponding to the designated event position is obtained. This is a pointer list sorted by time (26 in FIG. 2C).
This is a process for obtaining a pointer corresponding to a position specified on the screen with reference to (0). Next, in step 503,
The event data pointed to by the pointer is referred to.

At step 504, it is determined whether or not the event data belongs to an editable block. If so, the display of the event data is inverted in step 505, and the process returns in step 506 after accepting editing such as changing, inserting, and deleting various values of the event data. If the event specified in step 504 is not an event of an editable block, a warning message indicating that the event data cannot be edited is displayed in step 507, and the process returns.

If it is necessary to redisplay the result of the editing, steps 403 to 409 of the list display in FIG.
The re-display may be performed by the above processing. Also, display 1
Also, when an instruction to change a plurality of blocks or an instruction to change an editable block is issued, the display may be performed again by the process of FIG.

Next, a second embodiment of the present invention will be described. In the second embodiment, the configuration of the electronic musical instrument is the same as that of FIG. 1, and the configuration of the automatic performance data is the same as that of FIG.

FIG. 6 shows an example of a display screen when the automatic performance data is displayed and edited in the second embodiment. In this device, a conventionally known window system operates similarly to the first embodiment, and automatic performance data of one music to be displayed and edited is displayed in one window 600. A window 600 includes an event display area 601 for displaying event data in a piano roll format.
It has. On the right side of the event display area 601, a scroll bar 606 for scrolling the display screen of the event display area 601 up and down is provided. Below the event display area 601, the event display area 60
A scroll bar 607 for scrolling the display screen 1 left and right is provided. By operating these scroll bars 606 and 607, any event data of the automatic performance data to be displayed and edited can be displayed.

On the left side of the event display area 601, a display 602 (coordinate axis indicating the pitch) of the keyboard of the piano is displayed, and above the event display area 601, a display 604 (measurement position from the beginning of the music) is displayed. A coordinate axis indicating the occurrence and duration of the event is displayed. Especially the keyboard display 60
On the second line, note names “C3” and “C
The characters "4" and "C5" are displayed. In FIG. 6, the bar display 604 displays the second half of the 52nd bar to the first half of the 55th bar.

Reference numeral 603 denotes a piano roll display area in which event data is displayed as a horizontally long rectangle (bar) at a time position indicated by a bar display 604 of a pitch indicated by a keyboard display 602. The left end position of the bar indicates the event occurrence time (sound generation start timing), the bar length indicates the event continuation time (gate time), and the left end position of the bar indicates the event end time (sound generation end timing). I have.
For example, the bar display 611 indicates the tone having the note name B4 as the 54th tone.
This shows a note event that is pronounced with a length of 1/2 beat from the beginning of the fourth beat of the measure. The same applies to other bar displays. The display color of the bar display is different for each block to which the event belongs. Further, the bar display corresponding to the event belonging to the editable block is highlighted by solid color. The bar display corresponding to the event data belonging to the other non-editable block is not highlighted in a blank (only the frame).

In FIG. 6, since the bar indications 611 and 612 are highlighted in solid colors, it can be seen that the events corresponding to these bar indications belong to the editable block. Since the bar displays 621 and 622 are displayed without emphasis and are hollow, it can be seen that they do not belong to the editable block. In FIG. 6, the difference between the display colors of the bar display is indicated by a solid line and a dotted line. Further, the bar displays may overlap, but the bar displays corresponding to the events belonging to the editable block are always displayed at the uppermost position so that confirmation and editing can be prepared.

Reference numeral 605 denotes an editable block. FIG.
Now, since "Block1" is displayed,
It can be seen that the block whose block number is 1 can be edited. By inputting a block number in this area 605, or by clicking a downward triangle mark on the right side of this area with a mouse and selecting one from a list of blocks displayed, an editable block can be switched.

In FIG. 6, when the mouse pointer is placed on a bar display which is displayed in a solid color, the shape of the mouse pointer is changed for editing. FIG. 8B shows the shape of a mouse pointer for editing. A normal mouse pointer has an arrow shape pointing to the upper left. When the mouse pointer is positioned near the center of the bar display, a shape 811 with arrows above and below is obtained. When the mouse pointer is positioned near the left end or near the right end of the bar display, shapes 812 and 813 with left and right arrows are displayed.
become.

With the mouse pointer positioned near the center of the bar display and in the shape 811, the entire bar display is dragged and moved arbitrarily up, down, left and right, and dragged to an arbitrary time position at an arbitrary pitch. Can be dropped.
This is an editing operation for changing at least one of the pitch and the sounding timing while keeping the gate time of the event corresponding to the bar display. With the mouse pointer positioned near the left end of the bar display to form the shape 812, the left end of the bar display can be arbitrarily moved left and right by dragging and dropping. This is an editing operation for changing the sounding start timing and the gate time without changing the pitch and the sounding end time (the right end position of the bar display). With the mouse pointer positioned near the right end of the bar display and in the shape 813, the right end of the bar display can be arbitrarily moved left and right by dragging and dropping. This is an editing operation for changing the gate time without changing the pitch and the sound generation start timing (the left end position of the bar display).

Next, a procedure for performing the piano roll display of the automatic performance data described in FIG. 6 and editing the data on the display screen will be described. First, it is assumed that the user instructs display and editing of automatic performance data by an operation (not shown) (menu selection or predetermined key operation). At this time, the automatic performance data to be edited is specified by the user.

FIG. 7A shows a procedure of a piano roll display processing routine executed when display and editing of automatic performance data is instructed. Steps 701 to 703 correspond to FIG.
Since steps 401 to 403 are the same, description thereof will be omitted. In step 704, display data is created while sequentially referring to the events in accordance with the pointer list (260 in FIG. 2C) of the sorted result. FIG. 7 (b)
9 shows the display data created in step 704. 1
One display data 720 created for one event data includes the data of the block number of the event, the left end position of the bar display, and the length of the bar display.
In the display data of FIG. 7B, similarly to the pointer list arranged in time sequence of FIG. 2C, the bar display data is arranged and retained in time sequence.

Next, at step 705, the first display data is referred to. In step 706, it is determined from the block number in the referred display data whether the display data corresponds to the event data of the editable block. If it's an editable block,
In step 707, a bar display based on the display data is displayed in a solid color with the display color of the block (for example, 611 and 612 in FIG. 6). If it does not correspond to the event data of the editable block in step 706, the bar display based on the display data is displayed in the display color of the block in step 708 (for example, 621 and 622 in FIG. 6). ). Steps 707 and 708
Thereafter, in step 709, it is determined whether the processing is completed, that is, whether or not all display data (FIG. 7B) has been processed.
If unprocessed data remains, the next display data is referred to in step 710, and the process returns to step 706 to repeat the process of determining whether the block is an editable block. Step 70
When the processing has been completed up to the final data of the display data (FIG. 7B) at 9, the piano roll display processing ends. In step 709, it is determined whether the data has been processed (displayed) up to the final data. However, when there is much display data, not all data can be displayed in the window 600. The control of which range of the entire display data is displayed in the window 600 is performed by the window system. With the above processing, the display as shown in FIG. 6 is made.

Next, the procedure for editing the automatic performance data on the display screen as shown in FIG. 6 will be described.

FIG. 8 shows the procedure of an editing routine for editing the automatic performance data. In step 801, the user specifies a bar corresponding to an event to be edited using the mouse 110 on the screen of FIG. In step 802, display data corresponding to the specified bar is obtained.
This is the display data sorted in chronological order (FIG. 7).
Referring to (b)), this is processing for obtaining display data corresponding to a bar specified on the screen.

In step 803, it is determined whether or not the display data corresponds to an event belonging to the editable block. If so, step 804
Then, the mouse pointer for editing shown in FIG. 7B is displayed according to the position of the mouse pointer. Then, in step 805, after receiving a change in the position or shape of the bar, the process returns. The process of step 805 accepts the operation of dragging and dropping the mouse pointer described in FIG. 6 and FIG. 8B near the center, near the left end, and near the right end of the bar display, and accepts the position and shape of the bar. This is a process for making a change. With the change of the bar display,
Each value of the event data corresponding to the bar display is also changed. If the bar specified in step 803 is not an editable block, a warning message indicating that the event cannot be edited is displayed in step 806, and the process returns.

If it is necessary to redisplay as a result of editing, step 7 of the piano roll display shown in FIG.
Redisplay may be performed by the processes of 03 to 710. Also, when an instruction to change one or a plurality of blocks to be displayed or an instruction to change an editable block is issued, the display may be performed again by the process of FIG. Actually, the process of changing the shape of the mouse pointer when the mouse pointer is moved to the bar and the process executed when the mouse is clicked or dragged and dropped are performed by different tasks. However, for the sake of simplicity, FIG. 8A shows a series of processes.
