2. Description of the Related Art Conventionally, in an electronic musical instrument such as an electronic piano, an electronic keyboard, a synthesizer, etc., it is possible to perform by playing a key on a keyboard. The tone color, volume, effect, and the like of the musical tone generated by the electronic musical instrument during the performance are controlled according to the set musical tone parameter information.

[0003] That is, when a player operates a key on the keyboard section, it is based on key information indicating the state of operation and tone parameter information such as tone, volume, and effect set by each operator on the operation panel section. The corresponding tone waveform data is read from the waveform data memory. The read musical tone waveform data is processed to generate a desired musical tone.

Some of such electronic musical instruments have an automatic accompaniment device that performs automatic accompaniment based on predetermined automatic accompaniment pattern data. Normally, in an automatic accompaniment device for an electronic musical instrument, an accompaniment pattern is stored in a chord based on a predetermined one, and key information detected in real time by depressing a chord detection key during a performance is recorded. Chord expansion was performed based on the accompaniment sound.

That is, as the automatic accompaniment pattern data, the type of each constituent sound constituting a reference chord (a C code of an accompaniment instrument such as a guitar or a piano which is set in advance according to the type of the corresponding rhythm) is specified. Note information including a key number for performing, a step time indicating a sound generation timing, a gate time indicating a sound generation time, a velocity indicating a key pressing speed (magnitude of sound generation), and repeat end information including a repeat mark indicating a repeat point. Are stored for each type of rhythm such as rock, waltz, and tango. In each rhythm style, the drum, bass, accomp, and other parts constituting the accompaniment sound are determined according to the rhythm.

Some of such electronic musical instruments include a sequencer capable of converting a performance performed by a player into data, recording the data in a memory, and then automatically reproducing and reproducing the data. . If this sequencer is used, in addition to the automatic accompaniment pattern data stored as the preset data as described above, it is possible to record the accompaniment pattern desired by the player by playing and then use it as an automatic accompaniment sound. Becomes

[0007]

When real-time recording (simultaneously converting the performance of a keyboard into data as it is and recording it) using this sequencer, for example, performance information of a simple melody section is recorded. While playing back the existing sequence data, an accompaniment is performed using a keyboard in accordance with the playback sound of the sequence data, and the accompaniment sound at that time is generally recorded.

However, many beginners who have not yet started playing music often do not yet fully understand the chord of the accompaniment sound, and it is difficult to accompany them by designating the chord in real time in accordance with the sequence data. It was very difficult. Even for beginners who are not accustomed to playing but understand the chords themselves, it is difficult to perform accompaniment at appropriate timing in accordance with the reproduction of sequence data.

The sequence data is generally provided with a plurality of recording tracks, and data of various parts such as melodic, bass, and chords are recorded on one track. for that reason,
The data of each part constituting the accompaniment sound is also recorded on a predetermined track.
When creating one accompaniment pattern, it was not possible to record a combination of phrases having different rhythms on a plurality of tracks. As a result, there is a problem in that the performance expression is limited, and it is not possible to enjoy music with rich expressive power.

The present invention has been made in view of such circumstances, and even a beginner who has just started playing music can easily create a desired automatic accompaniment pattern using a sequence track. It is an object of the present invention to enable recording of phrases having different rhythms in a track for each part in any combination.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a functional block diagram showing the elementary features of the accompaniment pattern data creation device of the present invention. In FIG. 1, reference numeral 1 denotes phrase data storage means in which automatic accompaniment phrase data of a plurality of parts is stored in advance as preset data for each rhythm style.

As described in the conventional example, the preset data is composed of note information of each constituent sound constituting a reference code (for example, C code) and repeat end information including a repeat mark or the like such as a lock, a waltz, a tango or the like. A plurality of sets are stored for each rhythm type, and each rhythm style is composed of parts such as a drum, a bass, and an accomp that constitute an accompaniment sound unique to the rhythm.

Reference numeral 2 denotes a phrase selection means for selecting a desired part of a desired rhythm style from the automatic accompaniment phrase data stored in the phrase data storage means 1. Reference numeral 3 denotes a phrase extracting unit which extracts automatic accompaniment phrase data of a desired part for the desired rhythm style selected by the phrase selecting unit 2 from the phrase data storage unit 1.

Reference numeral 4 denotes a phrase writing unit which writes the phrase data extracted by the phrase extraction unit 3 into a predetermined sequence track in the sequence data storage unit 5. Here, the sequence data storage means 5 is provided with a plurality of recording tracks, and data of various parts such as melodic, bass, and chords are respectively recorded on one track. The phrase data of the part selected by the selecting means 2 is written to one recording track.

Numeral 6 is an area designating means for designating which recording area to write in the sequence track in which the automatic accompaniment phrase data selected by the phrase selecting means 2 is written. The phrase writing means 4 writes the selected phrase data in the recording area specified by the area specifying means 6. Therefore, when the user specifies the recording area by using the area specifying means 6, for example, the selected phrase data can be written into a desired bar portion during a series of performances.

According to the accompaniment pattern data creating apparatus configured as described above, it is possible to select different rhythm styles and write phrase data in each of the different recording tracks provided for each part.
One piece of automatic accompaniment pattern data having various rhythm styles for each part can be created. Moreover, such automatic accompaniment pattern data creation processing does not need to be performed by designating a code in accordance with, for example, the reproduction of existing sequence data in which a melody sound is recorded, so that the accompaniment sound code is not well understood. Even beginners can easily create automatic accompaniment pattern data having various rhythm styles.

Generally, header information exists at the head of each sequence track, and tone color information set for the part is recorded therein. On the other hand, header information also exists at the head of each automatic accompaniment phrase data, and timbre information set for the phrase is recorded. Then, the timbre information set in the selected automatic accompaniment phrase data and the sequence track in which it is written may be different.

In the present embodiment, in such a case, a configuration may be adopted in which the user can select which tone color should generate a musical tone. For example, an ON / OFF switch is provided to specify whether or not to use the timbre information set in the header of the automatic accompaniment phrase data. When the switch is ON, the tone is set to the tone set in the header of the automatic accompaniment phrase data. Is generated, and in the case of OFF, a musical tone is generated in the tone color set in the header of the sequence track.

FIG. 2 is a functional block diagram showing another feature of the accompaniment pattern data creating apparatus of the present invention. FIG. 3 shows an embodiment of the present invention, and FIG. FIG. 4 is a diagram showing a specific example for explaining the operation of the data creation device. Hereinafter, description will be made with reference to FIGS.

In FIG. 2, phrase data storage means 1
Is substantially the same as that shown in FIG. 1, but in the case of FIG. 2, as shown in FIG. 3, the phrase data of a plurality of parts stored for each rhythm style are Each part has a plurality of variations (in the example of FIG. 3, the first rhythm style includes phrase1 to phrase1).
There are six variations of phrase6).

Numeral 7 denotes a variation selecting means for selecting a desired variation from a plurality of such variations. The phrase extracting unit 3 extracts from the phrase data storage unit 1 the automatic accompaniment phrase data of the desired rhythm style, the desired part, and the desired variation selected by the phrase selecting unit 2 and the variation selecting unit 7.

Reference numeral 8 denotes a code extracting means for extracting a code name from a designated track in existing sequence data recorded in the sequence data storage means 5 in advance. As shown in FIG. 2, the code extracting means 8 includes a judging means 8a and a code judging means 8b.

The judging means 8a determines that a key of three or more notes is present within a predetermined time in the existing sequence data (for example, a time within 5 to 10 clock signals constituting a quarter note length of 96). It is determined whether or not information is included, that is, whether or not three or more keys have been played within a predetermined time during the recording of the existing sequence data. When it is determined that the key information of three or more sounds is included within the predetermined time, the code determination means 8b performs a normal code determination process from the key information of three or more sounds.

In the example of FIG. 3, the code extraction is performed by designating the third recording track Trk3 (the track on which the code phrase is recorded) of the sequence data storage means 5, and as a result, the C code is obtained in the first and second measures. , F code at the third measure, 4
This shows that the G code was detected at the bar. In the present embodiment, a code track for recording the code information extracted by the code extracting means 8 is provided in addition to the tracks Trk1 to Trk40 for recording normal pattern data. The detected code information can be arbitrarily edited thereafter.

Numeral 9 denotes a code expanding means, which expands the code of the phrase data of the reference code extracted from the phrase data storing means 1 in accordance with the code name extracted by the code extracting means 8; Is supplied to the phrase writing means 4. The code expansion process is performed by adding codes relating to the root (root tone) and code type of the code detected by the code determination to the extracted reference code pattern. Phrase writing means 4
Writes the data after the code development by the code development means 9 to a predetermined recording track in the sequence data storage means 5.

In the example shown in FIG. 3, the phrase data of the base part according to the first variation in the first rhythm style is expanded according to the F code and the G code extracted by the chord extracting means 8, and the expanded data is obtained. Is the second recording track of the sequence data storage means 5.
3 to 3 in Trk2 (the track on which the bass phrase is recorded)
This indicates that writing is to be performed at the fourth bar.

The writing of the selected phrase data in the third and fourth measures can be specified by the area specifying means 6 as described with reference to FIG. 1, but in the example of FIG. It is specified by another method. That is, when a track from which a code is to be extracted is specified, the processing range in that track is specified as the third to fourth measures. At this time, the code extracting means 8 performs the code extracting process only within the specified range, and writes the phrase data expanded according to the extracted code name only into the portion corresponding to the specified range.

In the case of the configuration as shown in FIG. 2, when the automatic accompaniment phrase data is written into the sequence track, the phrase data of the reference code read from the phrase data storage means 1 is expanded after the code expansion. When the performance is performed by reproducing the automatic accompaniment pattern data created as described above, the player does not need to perform a keyboard operation for designating a chord in accordance with the performance. Therefore, even beginners who do not understand the chord of the accompaniment sound well can enjoy playing without being conscious of the chord.

In the case of the accompaniment pattern data creating apparatus shown in FIG. 1, the created automatic accompaniment pattern data is recorded in the form of a reference code. There is. Therefore, also in this case, by providing the chord extracting means 8 and the chord expanding means 9, it is possible to eliminate the necessity for the player to perform a keyboard operation for designating the chord in accordance with the performance.

As shown in FIG. 2, if the code is developed in advance and written in the sequence data storage means 5, when the data recorded in the sequence track is edited,
There is an advantage that the contents of the recording data can be easily understood by the editor. That is, if the reference code is recorded as it is as shown in FIG. 1, no matter what chord is actually produced, all the chords are the same on the sequence track, and it is difficult to identify them. In the case of FIG. 2, such inconvenience can be solved.

By the way, as described above, the code extracting means 8
Is configured to first determine whether or not key information of three or more sounds is included within a predetermined time in existing sequence data, and to perform code determination only when key information is included. Therefore, since such processing takes a certain amount of time, the timing of chord name extraction may not be accurately at the beginning of an eighth note, a sixteenth note, or the like.

In order to cope with such a case, the code extracting means 8 performs a quantization process for correcting a shift in sounding timing due to the extraction of a chord name when extracting a chord name from existing sequence data. You may comprise. Since the chord extraction is basically established when three or more keys are depressed, as shown in FIG. 4B if there is no quantize function, it becomes as shown in FIG. 4A if there is a quantize function. Therefore, it is possible to record the automatic accompaniment phrase data at an accurate timing such as an eighth note and a sixteenth note, and it is possible to easily produce accurate synchronized automatic accompaniment pattern data.

Usually, the automatic accompaniment pattern data having various rhythm styles in one pattern described above is
In some cases, the desired item can be created at one time, but in general, the desired item is finally created through trial and error.
However, when writing the selected phrase data into the sequence data storage means 5, if the track to be written is empty, the selected phrase data is inserted as it is, but if note data has already been written, the selected phrase data is inserted. Overwritten on top.

Therefore, even if it is desired to use the data before updating again, the data cannot be used because it has been erased by overwriting. Also, once the phrase data has been written, the process must be repeated from the beginning in order to write again, which is troublesome. Therefore, in the present embodiment, the rehearsal means 10 and the rehearsal instruction means 11 are provided in order to solve such inconvenience.

That is, the rehearsal means 10 selects the desired automatic accompaniment phrase data by the phrase selecting means 2 and the variation selecting means 7 and then selects the selected automatic accompaniment phrase data (which is developed by the code developing means 9). And sequence data storage means 5
Tone generation is performed using both of the existing sequence data in the above. An instruction as to whether or not to perform such a rehearsal performance is made by the rehearsal instruction means 11.

When the rehearsal means 10 is provided in this manner, before the selected desired automatic accompaniment phrase data is actually written on the sequence track, the selected phrase data and the existing sequence data before the writing thereof are written. It is possible to perform using both of
It is possible to confirm in advance whether the created automatic accompaniment pattern is as desired.

Each of the blocks 1 to 11 described above
Are CPU, ROM and RAM in the present embodiment.
And an operation panel (including a display indicating an operation state and a menu) used for cutting and pasting the automatic accompaniment phrase data as described above. The rehearsal means 10 includes a tone generator for forming an analog tone signal based on the phrase data from the chord expanding means 9 and the sequence data from the sequence data storage means 5, and a sound emitting section based on the formed tone signal. Speaker.

The tone generator has a plurality of tone generating channels and is configured to generate a plurality of tone simultaneously. The tone generator generates tone data in a digital data format based on key number information and tone parameter information (rhythm, tone color, volume, effect, etc.) representing each key sent from the CPU, and converts the tone data into D / D data. A conversion is performed to form an analog tone signal.

FIGS. 5 and 6 are diagrams for explaining a processing procedure when actually creating automatic accompaniment pattern data using the accompaniment pattern data creating apparatus according to the present embodiment configured as shown in FIG. FIG. 5 is a flowchart showing the processing procedure, and FIG. 6 shows an example of an operation panel used in the course of the processing. L1 to L4 shown in FIG.
Each of the operators R1 to R4 and F1 to F8 is for giving an instruction to a menu or the like displayed on the operation panel.

In step S1 of FIG. 5, a sequence track from which a code is to be extracted and a desired range within the sequence track are designated.
Performs processing to extract a code name from the sequence data within the specified range. FIG. 6A shows a display example of the operation panel at this time. In the following description, a track from which a code is to be extracted is referred to as a “seed track”.

As shown in FIG. 6A, this step S
In step 1, the number of the seed track is designated using the R1 key. In addition, the L1 key is used to set from which bar of the seed track the code is to be extracted, and the L2 key is used to set how many bars are to be subjected to the code extraction. The range set in this way is "St
3 are displayed in the columns of "art Bar", "Length", and "End Bar", where the contents set by these operators R1, L1, and L2 match those in the example of FIG.

After specifying the seed track from which the code extraction is to be performed and the range therein, the F7 key (Anl
When z) is pressed, the specified area of the seed track is analyzed, and the analysis result of the code is written to the code track. Thereafter, when the F8 key (Cont) is pressed, the screen shifts to the next screen shown in FIG. 6B, and then the process of step S2 in FIG. 5 is performed.

In step S2, using the L1-L4 and R1-R4 keys for switching between ON and OFF, it is set which part of the phrase is to be generated.
Specify the track number where you want to write the generated phrase. Here, it is possible to select a plurality of parts. For example, up to seven parts can be generated, and are composed of an accomp (AC1 to AC4), a bass (BAS), a drum (DRM), and a percussion (PRC).

Next, in step S3, the user operates a setting dial (not shown) below the screen shown in FIG. 6C to select a genre (rhythm style) of the phrase to be generated. In the next step S4, by pressing any of the F2 to F7 keys below the screen shown in FIG. 6D (six variations are prepared in the present embodiment), the phrase to be generated is generated. Select a variation. Then, a phrase is selected in step S5.

Thereafter, in step S6, when the start key is pressed with the desired phrase selected as described above, a rehearsal performance (simultaneous reproduction performance of the sequence data and the selected phrase data) is performed. Listen to this rehearsal performance and if you like the phrase,
By pressing the R4 key (Paste) in the next step S7, the selected phrase data is expanded in code and written in the track designated in the previous step S2.

At this time, the R3 key (With Program On)
Is turned on, the header information unique to the selected phrase is also written. As a result, with respect to the written phrase, a musical tone is generated in the tone color set for the phrase. On the other hand, if it is set to OFF, the header information unique to the selected phrase is not written, and only the phrase data is written.
A tone is generated by the tone set in the header information of the recording track.

Also, if the rehearsal performance is heard and the user does not like the selected phrase, the phrase may be selected again. In this case, if the user wants to change the variation, he or she can perform the operation while keeping the screen shown in FIG. 6D, or if he wants to select the rhythm style again, press the F1 key (Back)
Press to return to the previous screen. As described above, in the present embodiment, the rehearsal performance can be performed before the phrase data is actually written, so that the current recording state can be used as it is, and the phrase selection can be performed. Does not need to be redone from the processing in step S1 and can be performed very easily.

As described above in detail, according to the present embodiment, when a user composes a piece of music, he or she selects some desired rhythm styles, desired parts, and automatic variation accompaniment phrase data of a desired variation, and selects them. Advanced accompaniment patterns can be created simply by combining them arbitrarily. The accompaniment pattern can be changed until you like it. If you like it, you can write all the data as actual data on the sequence track and make further edits.

In this case, for example, a sequence track in which a chord idea of a simple tune is recorded is used as a seed track, and the accompaniment pattern data creating apparatus of this embodiment analyzes the seed track to extract a chord name. Since the data obtained by performing code expansion according to the extracted code name is written as actual data, there is an advantage that the recorded data can be easily understood when editing.

[0063]

As described above, according to the present invention,
By writing auto-accompaniment phrase data of different rhythm styles in a plurality of sequence tracks, one auto-accompaniment pattern data can be created, and at that time, an operation of designating a chord according to the playback sound of the existing sequence data is performed. Since there is no necessity, anyone can easily create automatic accompaniment pattern data capable of high-level expression having various rhythm styles in one pattern. As a result, when a user composes a song,
It is also possible to easily edit an existing song.

According to another feature of the present invention, code extracting means for extracting a code name from existing sequence data,
When the automatic accompaniment pattern data created on the sequence track is reproduced, a chord expanding means for expanding the chord according to the chord name extracted by the chord extracting means is provided. It is not necessary to perform a keyboard operation for designating a chord in accordance with, and even a beginner or the like can easily perform under correct accompaniment sound.
