Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music composition device that composes music on a display screen of a display device using a computer or the like.

[0002]

2. Description of the Related Art Conventionally, a musical score is utilized by a computer,
An example of a device to be created is disclosed in Japanese Patent Publication No. 3-24679. This device displays a staff and a group of notes on the screen, selects each note from the group of notes with a light pen and writes it on the staff. It is a system for making music score automatically.

In addition, music score creating software for a personal computer (for example, trade name "Band in a"
BOX ”and the like) are commercially available. In creating a musical score, first, a music style (accompaniment style such as jazz, waltz, etc.) is specified for a sheet, and then accompaniment patterns and chords are sequentially packed from the beginning of a bar to compose music. Alternatively, at the transition of the accompaniment pattern, the next accompaniment pattern number is written (until the next accompaniment pattern is changed, the accompaniment pattern is repeated, the same operation as a so-called real-time automatic accompaniment instrument). In this method, all the accompaniment patterns of the style specified at the beginning become main patterns (orthodox patterns), and after that, only the specified part is made into fill-in or ending, and composition is carried out.

[0004]

The former musical score creating apparatus sequentially writes notes one by one on a time axis called a staff, thereby mechanizing the musical score creation that was performed by handwriting. Although it is possible to make it beautiful, the composition work of what kind of song is to be made is one in which the human being thinks of each note in his head, just as in the case of handwriting. It does not mean that the effort itself is reduced.

In the latter music score making software,
Since the accompaniment pattern and chords are written on the time axis managed by measures, the composition work can be relatively easy, but the musical style of the accompaniment pattern is only one selected prior to composition. Is limited to
There is a lack of flexibility in musical expression.

The present invention has been made to solve the above-mentioned problems, and reduces the labor of composition and
It is an object of the present invention to provide a music composition device with increased flexibility in music expression. Another object of the present invention is to provide a music composition device that, when a music performance is performed based on the obtained music composition data, allows the music performance to be performed in accordance with the set initial setting data.

[0007]

In order to achieve the above object, the present invention provides a storage means for storing a plurality of phrase data each having performance data and initialization data to be output prior to the performance data. A display means for displaying a phrase identifier representing each of the phrase data selected from the storage means on a display device, a track display means for displaying a time series corresponding to the progress of a song on the display device in a plurality of frames, Write means for writing an arbitrary one of the displayed phrase identifiers in an arbitrary frame of the track display means, and means for generating music data based on the identifier of the written phrase data, A plurality of channels are assigned to one, and the preceding phrase data of the written adjacent frames is assigned. Data to one channel and subsequent phrase data to another channel to generate musical sound data, and to initialize the subsequent phrase data from the final data portion of the preceding phrase data. , Music data generating means for generating the music data.

[0008]

According to the present invention, writing of any one of the phrase identifiers displayed on the display device to any one of the plurality of frames displayed on the display device by the writing means is repeated. The music data generation means generates music data in response to this writing.

Since each phrase data is provided with initial setting data prior to the performance data, when the performance is performed according to the composition data, the initial setting, for example, a tone color is set according to the initial setting data. It When one channel is assigned to one track, the tone color or the like is changed to that of the next phrase according to the initial setting data of the next phrase before the performance of one phrase is completed. In this case, the correct performance is not performed.

Therefore, when a plurality of channels are prepared for one track and the preceding phrase data is assigned to a certain channel, the phrase data written in the subsequent frame is assigned to another channel and the last of the preceding phrase data is assigned. From the data portion, the subsequent phrase data is initialized in the other channel, and the performance based on the subsequent phrase data is performed in the other channel.

[0011]

EXAMPLE As shown in FIG. 2, the composition apparatus of this example is as follows.
A personal computer 2, a display device 4 including a CRT or LCD, a keyboard 6, and a pointing device such as a mouse 8 are provided, and a floppy disk, a hard disk or a CD-RO (not shown).
Programs and data stored in a recording medium such as M are read into the personal computer 2, and music data is created by operating the keyboard 6 or the mouse 8.

The created music data is converted into a MIDI signal, which is event-type automatic performance information, by an automatic performance device (not shown) composed of software in the personal computer 2 and a MIDI interface 10, and MIDI is generated. It is supplied to the sound source 12. The MIDI sound source 12 generates sound source signals of various parts in analog waveforms based on MIDI data, and is supplied to an acoustic device 14 including, for example, an amplifier and left and right speakers.

In this music composition device, a spreadsheet-like song map 16 is displayed on the screen of the display device 4 as shown in FIG. This song map 16 has a plurality of tracks Track1 to Track4, Bas in the row direction.
s and Drums, and frame f in the column direction
have a ram. In FIG. 1A, the frame is displayed from the first column to the sixth column, but actually, more columns are prepared, and the columns displayed can be changed to the first column by operating the icons 18 and 19. It is possible to change to columns other than the 1st to 6th columns. Each of these frames shows the progress of time in each track.

At the top of the song map 16, phrase tables 20a to 20h are displayed. Each phrase table 20a to 20h has a musical instrument icon 22a to 22h and a phrase name 24a to 24h, respectively.
It consists of Each phrase table 20a to 2
0h corresponds to phrase data prepared in advance, for example, in the standard MIDI file format.

Of the phrase tables 20a to 20h, a musical instrument icon of a desired phrase table is dragged with the mouse 8 and dropped on a desired frame of a desired track on the song map 16 to thereby display the above-mentioned frame on the frame. You can paste the dragged phrase. By repeating such a pasting operation (drag and drop), each phrase data is linked to form song data, and composition can be performed. On the right side of the phrase tables 20a to 20h,
The eraser 25 is displayed. This is for deleting the pasted phrase.

Each phrase data is roughly classified and provided corresponding to the tone color of various musical instruments, for example, drum, bass, guitar, synthesizer, keyboard instrument, string instrument, wind instrument, and others. In addition, various phrase data are prepared in advance for the tone colors of the same type of musical instrument, depending on the tone colors and playing styles of a plurality of musical instruments. For example, in the case of a guitar tone, for example, an electric guitar tone and a rock style, an electric guitar tone, a jazz style tone, an acoustic guitar tone, a rock style tone, and an acoustic tone A variety of guitar tones, such as jazz style, and various phrases with the same tone and the same style, are prepared. Although details will be described later, these phrase data have different tone color data for each phrase data. A phrase name is attached to each of these phrase data. Further, musical instrument icons are prepared in advance so as to correspond to these phrase data.

An icon table showing which musical instrument icon is associated with the tone color data of each phrase data,
An instrument group table indicating which timbre data belongs to which instrument group is prepared in advance. When a phrase table corresponding to a certain type of musical instrument, for example, a phrase name in the phrase table 20g, for example, 24g, is clicked with the mouse 8, the tone color data in a plurality of phrase data in the storage means is used to use the musical instrument group table. As shown in FIG. 1, a list of phrase names of each phrase data belonging to the group, that is, a phrase list 26 is displayed. In this way, only phrase names that belong to the same group are listed in phrase list 2.
6, the desired phrase data can be easily selected.

When a desired phrase name is selected from the phrase list 26 by clicking the left button of the mouse 8, the musical instrument icon corresponding to the tone color data in the phrase data of the phrase name is displayed by using the icon table. It is displayed in the phrase table corresponding to the phrase list 26, and at the same time, the phrase name is displayed in the phrase table. Therefore, by looking at the musical instrument icons 22a to 22h, it is possible to visually confirm what kind of phrase it is. Therefore, it is possible to easily imagine the contents of the phrase that were difficult to understand only by the phrase name, and it is easy to select the phrase. become. If the phrase list 26 is selected by clicking the right button of the mouse 8, the phrase list 26 can be hidden.

This musical instrument icon can be displayed by displaying the one corresponding to the tone color data in the phrase data corresponding to the phrase name in the clicked phrase list. The visual display is not limited to the musical instrument icon. For example, the note-on and note-off information in the phrase data is read to display the piano roll in a simplified manner, and the clock in the phrase data is also displayed. You may check the length and change the horizontal length of the icon.

The phrase tables 20a to 20 are also provided.
When the musical instrument icons 22a to 22g of h are double-clicked with the mouse 8, the phrase corresponding to the phrase table is played. Therefore, it is possible to listen to the phrase to be pasted, confirm whether it is the desired phrase, and then paste. In this case, although the tempo data is also included in the phrase data, it is performed based on the performance tempo data designated as the tempo of the song as described later. That way, you can audition in a state closer to the actual performance.

As shown in FIG. 1B, each phrase data has, for example, performance data (for example, note data) 28 for four measures, and prior to this performance data 28, initial setting data (for example, tone color data and , Part volume data)
It has one bar, that is, an aftact bar 30.

After the phrase is pasted into each frame, when the displayed place top button 32 is clicked with the mouse 8, the performance is started based on the song data. At the first performance after the phrase is pasted, each phrase data is linked and synthesized to generate performance data (song data) for the MIDI sound source 12, and is stored as music data. Then, when the music data is generated, a process of assigning two channels to one track is performed. For example, tracks Track 1 are assigned MIDI channels 1 and 2, tracks Track 2 are assigned channels 3 and 4, ... Track B
Channels 9 and 10 are assigned to ass, and channels 11 and 12 are assigned to track Drums.

The performance by the generated music data is, for example, as shown in FIG.
As shown in (b), the frame frame1 is played on channel 1, and the frame frame2 is played on channel 2. Below, channel 1 alternately
And channel 2 will perform.

This is because each phrase data includes the aftact measure 30. Therefore, when each such phrase data is assigned to one channel, the last one measure of the preceding phrase data and the aftact of the following phrase data are assigned. Since it overlaps with the measure 30, the tone and volume of the last one measure of the preceding phrase data changes to the tone and sound volume of the subsequent phrase data according to the initial setting data of the avertact measure 30 and the correct performance cannot be performed. is there.

Such channel allocation is performed by discriminating whether the frame is an odd number or an even number. For example, in the case of frame frame1, since it is an odd number, channel 1 is assigned and frame frame2
In this case, since it is an even number, channel 2 is assigned.
The performances after the first time after the phrase is pasted (the performances after the second time) are performed by the stored music data.

Since the aftact measure 30 is provided in this manner, it is also possible to create phrase data in which the aftact or anticipation is given to the measure 30. Further, as is apparent from FIG. 1 (b), between the last measure of the phrase data played on the same channel and the aftact measure of the phrase data played next, three measures are used in this embodiment. Since there is a space, the number of bars of each phrase data can be set to any bar up to 7 bars in this embodiment by utilizing this.

As for the progression or tonality of the chords of each phrase data, use a predetermined constant for all phrase data so that no matter how the phrase data are pasted, they will be musically matched. There is. This allows even beginners without knowledge of chords to freely select and compose phrases. Further, the chord progression or tonality may be designated, and the phrase data may be processed so as to match it.

When the place top button 32 is clicked again with the mouse 8 in the playing state, the playing is stopped. Also, the performance by the place top button 32 is
All frames of all tracks are played, but if you click a specific track name with the mouse 8, you can play only all frames of that track, and if you click a specific frame number, all tracks belonging to that frame Can be played. Also, when a musical instrument icon attached to a specific frame of a specific track is clicked, only the phrase data corresponding to the musical instrument icon can be played.

As shown in FIG. 1A, the song map 1
A tempo slider 34 is displayed below 6, and the knob portion 34a of the tempo slider is used for the mouse 8
By dragging and dropping by
The performance tempo of song data can be changed. Further, the performance tempo can be changed by 10 by clicking on both sides of the picked portion 34a, and the performance tempo can be changed by 1 by clicking the arrows on both ends of the tempo slider 34.

A random shaker 36 is also displayed to the left of the tempo slider 34. For example, when the random shaker 36 is double-clicked with the mouse 8 while the phrases are pasted on the song map 16, the phrases are rearranged at random and a new song is composed. However, in this case, in the bass track Bass, only the bass phrase is changed to the drums track Drum.
In s, only drums phrases can be rearranged.

Also, by dragging the random shaker 36 with the mouse 8 and dropping it on the song map 16, one new frame in which phrase data is randomly combined can be created. Even in this case, only the bass phrase is pasted on the bass track Bass, and only the drums phrase is pasted on the drums track Drums.

As is apparent from the above description, in this embodiment, each processing is performed in response to the operation of the mouse 8, that is, the occurrence of an event. Therefore, the process performed by the personal computer 2 is schematically shown in a flowchart of FIG. That is, first, the initialization routine is executed (step S2), various data such as phrase data is read from the recording medium, and the screen as shown in FIG. 1 is displayed on the display device 4. Then, it waits for the occurrence of an event (step S4). When an event occurs, it is determined what kind of event it is (step S6), a process corresponding to the determined event is performed (step S8), and the process returns to step S4.

The above-mentioned events and the processes performed in accordance with the events are shown in the form of a list as follows. The left side is each event, and the right side is the corresponding processing. In step S6, it is determined which event is on the left side, and processing is performed according to the event determined in step S8. Drag the phrase table ...

In the above embodiment, one phrase is composed of four measures of performance data and an aftact measure preceding this, but the performance data is not limited to four measures, and may be any number of measures. be able to. Further, in the above embodiment, one track is assigned to two channels, but it can be assigned to more channels.
Further, the total number of tracks is six, but the number can be arbitrarily increased or decreased.

[0035]

As described above, according to the present invention, any one of the phrase data displayed on the display device is written to any one of the plurality of frames displayed on the display device. Since music can be composed by writing by means, the labor of composing can be reduced. Further, as the music style, any one of the phrase data can be selected and freely combined, so that flexibility in expression of music can be increased.
Further, according to the present invention, each phrase data is provided with initial setting data prior to performance data,
When multiple channels are prepared for one track and the preceding phrase data is assigned to a certain channel,
The phrase data written in the subsequent frame is assigned to another channel, the initial setting of the subsequent phrase data is performed in the other channel from the final data portion of the preceding phrase data, and the subsequent phrase data is used in the other channel. Since the performance is performed based on, the performance according to the set initial setting data is performed when the performance is performed.
