BACKGROUND OF THE INVENTION
The present invention relates to a performance information editing apparatus and program suitable for accurately inputting performance information such as percussion instruments.
[0002]
[Prior art]
Conventionally, as a method for editing performance information, there is a method in which a percussion instrument is assigned to each line (pitch) of a staff score displayed on a display in a performance data (event) input mode. In this method, when a certain place on the staff is clicked, the type of percussion instrument is determined by the line position of the clicked position, and the pronunciation time is determined by the column position. The sound data of the percussion instrument whose instrument type and sound generation time are determined in this way is displayed and recorded as performance information.

As shown on the left side of FIG. 2, one piece of music data includes setting information for setting a playback mode at the time of automatic performance such as tempo, and performance data of a melody part, chord part, and rhythm part. The “code part” is performance data of accompaniment parts other than the rhythm part, and the performance data of each part is basically composed of a set of data representing timing and events.
[0017]
For example, as shown in the right side of FIG. 2, the performance data of the rhythm part is a set of “processing timing” data and “rhythm event” data processed at this processing timing arranged in time series. It is. This rhythm event is information representing the type and volume of a percussion instrument. Specifically, the rhythm event is a note-on event, and the type of percussion instrument is represented by a note number, and the volume is represented by velocity.
[0018]
[Configuration example of setting table]
In the performance information editing system according to one embodiment of the present invention, when performance data (event) is input, performance data can be efficiently input by selecting a percussion instrument type or line using a setting table. FIG. 3 is a diagram showing a configuration example of a setting table used in the performance information editing system according to one embodiment of the present invention.
[0019]
As shown on the left side of FIG. 3, this setting table corresponds to an event input screen (described later) or a display position in the vertical direction of a musical score, “first row”, “second row”, “third row”, As described above, a plurality of “lines” are set, and the percussion instrument performance allocation state for each of the plurality of lines is recorded, and is recorded in the table storage area of the ROM 3 or the external storage device 5. When inputting performance data (events), for example, a setting table recorded in advance in the ROM 3 can be used as it is by default, or this setting table can be changed by the user by table change processing. The table can be stored in the external storage device 5 via the RAM 4.
[0020]
In the setting table, as shown on the right side of the figure, the data of each line includes “display position” data representing the “line” position in the vertical direction with respect to the event input screen or the score, and the names of percussion instruments assigned to the line. “Percussion instrument name” data, “Percussion instrument type” data, “Display format” data, and the like representing the type and display format. Here, the “percussion instrument type” data represents a percussion instrument type such as a bass drum, a tom tom (A, B), a snare drum, a hi-hat cymbal, or the like with a note number. The “display format” data is data representing the shape of a note to be displayed on a score so that the percussion instrument type can be visually identified. For example, the shape of a note head (a slant ellipse of a normal note, ○, □, × , Symbols, etc.) and the stem stem display direction (upward or downward).
[0021]
The “display position” and “percussion instrument type” (note number) are set independently, and the percussion instrument type (note number) can be set regardless of the pitch represented by the line position on the staff. On the event input screen, there are about ten input “lines”, and one percussion instrument type can be assigned to each line. There are more types of percussion instruments that can be set (for example, 127 pieces (number of note numbers = 8 bits)) than the number of assignable lines. Therefore, the percussion instrument to be displayed on the performance data screen can be changed appropriately. Select.
[0022]
The “percussion instrument name” data is data indicating a percussion instrument name defined by the “percussion instrument type” data, and a corresponding character string and / or icon is displayed on the screen based on the “percussion instrument name” data. (In other words, a character string and an icon displayed on the screen are associated with “percussion instrument name” data).
[0023]
[Screen display example]
FIG. 4 shows a display example of an event input screen according to one embodiment of the present invention. Here, the outline of performance information editing in the performance information editing system according to an embodiment of the present invention will be briefly described with reference to FIG. 4. In this performance information editing system, musical performance data ( The performance information is edited by sequentially arranging events in the predetermined direction on the event input screen MW. When an instrument type selection screen SW or the like is used to set an instrument type (note number) or a line that is an object of an input event, and an instruction to input an event is given to the display screen MW, this instruction is displayed. In response, an event mark (note) corresponding to the instrument type is displayed at a position where the “column” position matches the time position where the instruction is given and the “row” position corresponds to the set instrument type. The event data marked on the display screen MW is recorded in the rhythm part of the music data together with timing data corresponding to the position on the time axis of the event, and stored in a predetermined storage area of the external storage device 5. Note that a predetermined standard value is assigned here for the volume (velocity) of the event data, and can be arbitrarily edited by another method.
[0024]
In the example of FIG. 4, in event input, a percussion instrument type (or line) selection screen (subwindow) SW is displayed on the display 13 in addition to the event input screen (main window) MW. The event input screen MW has a data input area that can be scrolled in the time axis direction (lateral direction) by operating the scroll button SBt or the scroll bar SBr.
[0025]
The event input screen MW is also referred to as a “drum score” screen. In the data input area, there are about 10 or more input lines in the vertical (up and down) direction with a staff score interposed between them. You can assign two percussion instrument types. The position in the horizontal (left / right) direction defines the timing of the event to be input, and the bar line (solid line) BL [number outside the area “1” is provided so that the timing of the input event can be easily grasped. "," 2 "represents a measure number. ], Auxiliary lines (beat lines: broken lines and dotted lines) AL are displayed at predetermined intervals. ,
[0026]
The percussion instrument type selection screen SW is displayed based on the setting table (FIG. 3), and is used for selectively instructing the percussion instrument type (or line) of the event to be input. In this example, the types of percussion instruments that can be input are displayed as character strings such as “bass drum”, “snare”,..., “1”, “2”,. “Line” number is displayed, and later, the display shape of a note displayed in the data input area of the event input screen MW when data is input is exemplified.
[0027]
In order to input performance data, the user first scrolls up and down the percussion instrument type selection screen SW with the cursor CL using the operation element 12 such as a mouse, and displays a desired percussion instrument type (for example, “bass drum”) on the screen. When the percussion instrument type (or line) is designated by clicking the button, the system is notified that data will be input for the percussion instrument type (or line).
[0028]
After specifying the percussion instrument type (or line), the user moves the cursor CL to the data input area of the event input screen MW, and moves the cursor CL to a desired position on the time axis as shown in FIG. When the click operation is performed, an event of a percussion instrument whose type has already been specified is input at a timing corresponding to the time axis position where the click operation is performed. At this time, in the data input area, as shown in FIG. 4 (2), the “row” (vertical direction) corresponding to the percussion instrument type on the time axis where the click operation was performed, regardless of the vertical position where the click operation was performed. A note having a display shape corresponding to the percussion instrument type is displayed at the position.
[0029]
The display example of FIG. 4 represents a state immediately before the bass drum data in the first row is input after the percussion instrument type “bass drum” on the percussion instrument type selection screen SW is selected. It is shown on the left side outside the data input area that the first line of the “drum notation” to be input corresponds to the track number “1” (“TRACK 1”). In addition, the data input area of the event input screen MW can be scrolled up and down with the up and down scroll buttons or the bar (the right side of the area), or the data input area can be expanded with the enlarge button (the lower right corner, etc.) Can be confirmed.
[0030]
The percussion instrument type selection screen SW [FIG. 4 (1)] can be hidden by operating the non-display button (upper right) or can be redisplayed by the “select percussion instrument type” display button SB [FIG. 4 (2)]. it can. In the example of FIG. 4 (1), the percussion instrument type is displayed as a character string in the percussion instrument type selection screen SW, but instead of this, an icon that abstracts the characteristic shape of each type of percussion instrument. By using, a percussion instrument type selection instruction can be operated intuitively and quickly.
[0031]
Alternatively, the percussion instrument type that is the target of data input may be selected by directly specifying the “line” position without using the percussion instrument type selection screen SW. For example, when an arbitrary position on the left side of the data input area of the event input screen MW is instructed by clicking with the cursor CL, the designated vertical position is detected to determine “row”, and the determined “row” is determined. A corresponding percussion instrument type may be selected as an input target. Or you may make it input the "line" number which operated the number key in the operation device 12 simply. In these cases, it is preferable that a list corresponding to the setting table is separately called on the display 13 so that the correspondence between “row” and percussion instrument type and display shape can be confirmed.
[0032]
[Operation example of main processing]
FIG. 5 is a flowchart showing performance information editing processing according to one embodiment of the present invention. This performance information editing process operates from the start of the “music data (rhythm part) editing program” to the end thereof. When the performance information editing process by the music data (rhythm part) editing program is started, the “drum score” screen MW [FIG. 4 (1)] is displayed on the display 13 in step S 1, and a new one to be edited from now on. Prepare to input rhythm parts for various music data.
[0033]
Here, when creating a new rhythm part on the “drum score” screen MW, only the drum score (staff, etc.) stored in advance in the ROM 3 or the like is displayed, but the rhythm part has already been created. When the music data is selected from the external storage device 5 or the like, an event display corresponding to the rhythm part data of the selected music data is added, and this event can be corrected by the following processing.
[0034]
In this example, in addition to the “drum score” screen MW, the user can select the type of percussion instrument (or “row” to be input) for which event data of the music data is to be input. Thus, for example, the percussion instrument type selection screen SW [FIG. 4 (1)] is also displayed.
[0035]
Next, in step S2, it is detected whether or not an instruction operation for selecting the type of percussion instrument to be input (or the input target line) has been performed. If it is determined that the percussion instrument type (line) is selected (S2 → YES), the process proceeds to step S3, and the selected percussion instrument type (or corresponding to the selected line) is set for the subsequent event input. Set the target. Further, when it is determined that the percussion instrument type (row) is not selected (S2 → NO) and after the percussion instrument setting process in step S3, the process proceeds to step S4, in the data input area on the “drum score” screen MW. It detects whether or not there is an instruction operation for inputting an event.
[0036]
For example, as shown in FIG. 4A, when there is an instruction to input an event by an operation of clicking the cursor CL at a certain position in the data input area (S4 → YES), first, in step S5 In response to the “percussion instrument type” set as the event input target, the row position of the note displayed on the “drum notation” screen MW according to the instructed input event (“input event display”) Row))) from the “display position” data in the setting table. Subsequently, in step S6, based on the position on the time axis at which the event input is instructed, the position of the note string (time axis direction) displayed on the screen MW as the input event corresponding to the position (“input event” Display column ”).
[0037]
In step S7, a note corresponding to the input event is displayed at a position on the screen corresponding to the display row and display column determined in steps S5 and S6 [see FIG. 4 (2)]. In step S8, “processing timing” data generated based on the display sequence determined in step S6 is generated, and “rhythm event” data (note-on) corresponding to the instructed input event is set to “processing timing”. Together with the data, it is recorded on a predetermined rhythm part track in the music data corresponding to the “percussion instrument type”.
[0038]
When it is determined in step S4 that there is no instruction to input an event (S4 → NO) and after the rhythm data recording process in step S8, the process proceeds to steps S9 and S10 in sequence. That is, if there is an instruction to change the contents of the setting table in step S9, the contents of the setting table are changed in accordance with the instruction, and other processing is performed in the next step S10. Other processes include a process of reproducing music data and a process of reading out events and generating musical sounds.
[0039]
In the subsequent step S11, it is detected whether or not there is an instruction to end the “music data (rhythm part) editing program”, and if there is no instruction to end the program, the process returns to step S2 and the above steps S2 to S11 are performed. Repeat the process. When there is an instruction to end this program, the performance information editing process by this program is ended.
[0040]
[Various Embodiments]
As mentioned above, although this invention was demonstrated about one Example, this invention can be implemented in a various aspect. For example, in the above description, a staff score drum score is used as an example of the screen, but other types of score scores can be used. Further, the screen may be of any display format as long as the display position is determined for each percussion instrument type and has a time axis. For example, a line score may be used, or a screen in which a plurality of lines are displayed along the time axis instead of the drum score may be used.
[0041]
In the embodiment, one percussion instrument is assigned to one row, but a plurality of percussion instruments may be combined to form a group, and one group may be assigned to one row. In this case, it is preferable that the percussion instrument input using the score is a specific one in the group, and that one can be freely set by the user.
[0042]
Furthermore, in the embodiment, the time is defined in “columns” with the time axis set in the horizontal (left / right) direction, the percussion instrument types are arranged in the vertical (vertical) direction orthogonal to the time axis, and the percussion instrument types are specified in “row”. However, on the event input screen, the arrangement direction of the percussion instrument types only needs to be orthogonal to the time axis. For example, when the time axis is the vertical (up and down) direction, the time is defined by “row”, and the types of percussion instruments are arranged in the horizontal (left and right) direction orthogonal to this, and the percussion instrument types are defined by “columns”. Good.
[0043]
【The invention's effect】
As described above, in the present invention, after selecting the type of percussion instrument that is the target of rhythm event input, the timing of the rhythm event is input using the event input screen (MW). When a certain point on the event input screen is designated by the button, the time axis position (“column”) of the designated point and the percussion instrument type axis position [“row” (height)] corresponding to the selected percussion instrument type are set. An event mark (“note”) corresponding to the percussion instrument type is displayed at a corresponding location on the screen. Therefore, according to the present invention, when the user inputs the timing of the rhythm event using the screen, the desired time axis position (column position) can be easily set without having to worry about the percussion instrument type axis position corresponding to the percussion instrument type. ) The event information can be entered at any percussion instrument type axis position, and the event display location will be the position of the percussion instrument type that is selectively specified. Various effects, such as being able to confirm the event mark and its display position, etc. are achieved. This makes it easy to input the desired performance information without paying any attention to the position (line position) corresponding to the percussion instrument type. can do.
