Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for inputting chord names for the purpose of automatic performance and automatic arrangement.

[0002]

2. Description of the Related Art Chords (chords) traditionally written on music scores
There is known an automatic performance device that inputs a chord and automatically plays an ensemble performance based on the input chord, and an automatic arrangement device that creates performance data for the ensemble performance based on the input chord. .

[0003]

However, the above-mentioned conventional automatic performance device and automatic arrangement device are designed to be able to input only the chords expressed in the most commonly used notation. Generally, there is not only one chord notation,
The notation is often different depending on the score even for the same chord. Therefore, even if the chord can be processed by the device, the operator may not be able to input the chord because the notation of the chord is different. For example, the chord “Cm7 ♭
5 ”may be written as“ Cm7-5 ”or“ Cφ ”, and even if a chord written as“ Cm7 ♭ 5 ”can be input, it is a different chord“ Cm7-5 ”or“ Cm7-5 ”. C
In some cases, "φ" cannot be input. In particular, there is a problem that it is very difficult for an operator who does not have knowledge of musical score such as chord to input the chord only according to the musical score.

In addition, from the viewpoint of memory capacity and operability, some devices are configured not to process chords that are used infrequently, and the chords may be replaced by other chords. Even if there was, the operator could not input.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a chord input device and an automatic performance device capable of inputting chords having different notations or unprocessable chords.

[0006]

In order to achieve the above object, the present invention uses a chord name inputting means for inputting a chord name and a chord name input by the chord name inputting means in a predetermined notation. If there is not, it has a conversion means for converting into a predetermined notation.

Preferably, a chord name input means for inputting a chord name, an interpreting means for interpreting the inputted chord name and performing a chord corresponding to the chord name, and the chord name input If the chord name input by the means cannot be interpreted by the interpreting means, it has a converting means for converting to another chord name that can be interpreted and substituted.

A chord name input means capable of inputting a chord name in a first notation representing a predetermined chord and also a chord name in a second notation representing the predetermined chord. And the chord name inputting means
Even if a chord name is entered by the notation of, or even if a chord name is entered by the second notation,
And a performance means for performing an automatic performance according to the predetermined chord.

[0009]

According to the structure of claim 1, when the chord name input by the chord name input means is not written in a predetermined notation, the conversion means converts it into a predetermined notation.

According to the structure of claim 2, if the chord name input by the chord name input means is a chord that cannot be interpreted and can be substituted by another chord, another chord can be processed. Converted to chords.

According to the third aspect of the invention, even if the chord name input by the chord name input means is in accordance with the first notation, it is in accordance with the second notation. Also, the playing means performs an automatic performance in accordance with the chord indicated by the notation.

[0012]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of an automatic knitting apparatus according to the present invention. In the figure, the automatic arrangement device of the present embodiment includes a keyboard 1, a switch group 2 for inputting various kinds of control information, a CPU 3 for controlling the whole, and a program memory 4 for storing a processing program executed by the CPU 3. And a working memory 5 for temporarily storing the calculation result and input information, a chord progression memory 6 for advancing the input chords in the order of performance, and a tone signal output based on the chords output from the chord progression memory 6. The automatic accompaniment device 7, the tone generator (TG) 8 that outputs a tone signal based on the note code output by the CPU 3 in accordance with the note name input by the keyboard 1, and various input information and calculation results are displayed. It is mainly configured by the display unit 9.

The output side of the automatic accompaniment device 7 and the output side of the tone generator 8 are connected to the input side of a mixing device 10 for mixing the tone signal outputs of both, and the output side of the mixing device 10 is a sound system such as a speaker. It is connected to the input side of the (SS) 11.

Further, the keyboard 1, the switch group 2, the CPU 3, the program memory 4, the working memory 5, the chord progression memory 6, the automatic accompaniment device 7, the tone generator 8, and the display 9 are interconnected via a bus line 12. Has been done.

FIG. 2 shows an example of the switch group 2 arranged on the input panel, and only the switches necessary for explanation are shown. In the figure, the switch group 2 of this embodiment is
A chord input switch 2 ₁ for inputting a chord, a return (RET) switch 2 ₂ for making the input chord one chord, and a start / stop switch 2 ₃ for starting or stopping the automatic accompaniment device. It is configured.

FIG. 3 is a diagram showing an example of a conversion rule for converting an input chord into a chord that can be processed by the automatic arrangement device of the embodiment. In the figure, "dim" indicates "diminished", "m" indicates "minor", "M" indicates "major", and "aug" indicates "augment". In (a), (c) and (d),
The notation to the left of each arrow is converted to the notation to the right.
"-" Shown in (b) means that when the symbol immediately after the symbol is "5" or before the symbol, "m", "sus4", "dim",
When there is "aug", it is in "♭", when it is immediately after "6" or "7", or before it is "m", "sus"
4 "," dim ", and" aug "are not present," m "
"M" is converted to "9", "11" or "13" immediately after the symbol,
If "#" and immediately after it are other than "9", "11", or "13", they are directly converted to "M". Here, “sus4” indicates “suspended force”.

Further, in FIG. 3, "add", "add" and "o" are added.
There is no rule for mitt "" Omit ". Further, these corresponding areas are not provided in the character array of FIG. 7 which will be described later. That is, in this device, "ad
The notation using "d" or "omitt" is not interpreted. For example, "Cadd9" means "C9" and "C".
7 omitt5 ”is not interpreted because it can be replaced with“ C7 ”in terms of music, so especially in the case of“ add ”and“ omitt ”, it is enough to just ignore it. It is easy and advantageous in terms of processing.

FIG. 4 is a flowchart of the main routine of this embodiment. In step S1, various parameters are initialized. Next, in step S2, key event processing for detecting whether or not the keys of the keyboard 1 and various switches are turned on / off is performed, and in step S3, when the start / stop switch 2 ₃ is pressed, the automatic accompaniment device 7 Processing is started when is stopped and stopped when it is operating. In the following step S4, it is determined whether or not the chord input switch 2 ₁ has been pressed in the process of step S2, and if it has been pressed, the following step S5
Then, a chord input subroutine process is performed, and when it is not pressed, step S5 is skipped and the process proceeds to step S6.
In step S6, other processes such as tempo adjustment are executed, and then the process returns to step S2 to repeat the above process.

FIG. 5 is a flow chart showing the details of the processing of the chord input subroutine (step S4 in FIG. 4) which is a feature of the present invention. First, in step S11, an input is made in the chord progression memory 6 described later. Memory (CPM (CP)) for storing the root note of a chord and memory (CPM (CP + 1)) for storing the type (chord type) of the chord
The pointer CP indicating the position of is reset (“0”), and in step S12, the memory CHR1 () for temporarily storing the input chord in the working memory 5 is cleared.

Next, a character or character string constituting the chord, labeled the score (hereinafter, referred to as "character or the like") is input by said chord input switch 2 _1, step S13
Then, the characters and the like are stored in the memory CHR1 () in the order of input.
Stored in, to repeat the input processing in step S13 until the return switch 2 ₂ is pressed at step S14. FIG. 6A shows an example of the chord stored in the memory CHR1 (). In the illustrated example, for example, the chord “Cau” is shown.
When gΔ7 ”is input, each character and the like is stored in the memory CHR1 by the loop of steps S13 to S14.
Arrays are arranged in the order shown in () in the area shown in (i).

In the determination routine of step S14,
When the return switch 2 ₂ is pushed, the process proceeds to step S15, in the region (ii) of FIG. 6 (a), i.e., the end end code such as characters constituting the chord is stored, the memory CH
The chord from the beginning of R1 () to the end code is regarded as one chord.

In the following step S16, the memory CH
The contents of R1 () are converted according to the conversion rule of FIG. 3 described above and temporarily stored in the same memory CHR1 () (FIG. 6 (b)), and the stored characters and the like are stored in the memory CHR2 () of the working memory 5. ) Character conversion processing is performed to rearrange the characters. FIG. 7 is a diagram showing an example of chords rearranged in the memory CHR2 (), and characters and the like stored in each storage area of the memory. In the figure,
Characters written in ":" to ":" are stored in the memory CHR.
2 () indicates characters and the like stored in each of the storage areas 1 to 3, and the characters and the like described in “:” are stored in the storage area in this priority order.

FIG. 8 is a flow chart showing the details of the subroutine of the character conversion processing in step S16 of FIG.

In the figure, in steps S31 to S34, the chords of the memory CHR1 () are converted according to the conversion rules of FIGS. 3 (a) to 3 (d), respectively, and are temporarily stored in the same memory CHR1 (). . At this time,
Step S31, Step S33 and Step S34
In, when the number of characters after conversion is increased, the data behind is shifted to the back, and when the number of characters after conversion is decreased, the data behind is padded to the front. That is, for example, when “Cφ” is input, first, the memory CHR1 () receives the data shown in FIG.
As shown in FIG. 9A, the characters and the like are stored in the order of input, and then the characters and the like are converted by the conversion rule.
"Cm7 ♭ 5" is the same memory CHR1
It is stored in (). At this time, since one character "φ" is converted into four characters "m7 ♭ 5", the trailing data "end code" is stored backward by three characters. On the other hand, for example, when "C7 + 5-9" is input, the chord is converted into "C7aug ♭ 9", and initially 2
Since the character "+5" is converted into one character "aug", the following data, that is, "♭", is stored one character before.

In the following step S35, the memory CHR1
The first character of () is stored in the memory ROOT in the working memory 5, and in step S36, the memory CHR is stored.
2 () is cleared, and in step S37, the conversion result converted in steps S31 to S34 is
According to the storage rule shown in FIG. 7 described above, the memory CHR2
The data is stored in each of the storage areas in (). Memory C of FIG.
HR2 () indicates the result of rearranging the chords stored in the memory CHR1 () in FIG. 6B according to the storage rule. That is, the first character or the like (“C”) and the last character or the like (“end code”) of the memory CHR1 () are excluded, and “au” is stored in the memory CHR2 ().
g ”is stored in the storage area, and“ M7 ”is stored in the storage area. Further, the memory CHR1 () in FIG.
The chord "Cm7 ♭ 5" stored in memory CHR2
When stored in (), "m" is stored in the storage area,
“7” is stored to the left of the storage area, “none” is stored in the storage area, and “♭ 5” is stored in the storage area. Here, the characters or the like stored in the respective storage areas are, depending on the chord of the memory CHR1 () to be referred to, the characters or the like described in the storage rule (characters or the like described in ":" to ":"). In some cases, “none” is stored. That is, nothing is stored in the area.

Next, returning to step S17 in FIG. 5, the input chord pattern table for determining the type of chord is compared with the contents of the memory CHR2 (), and the chord type determined as a result is worked. It is stored in the memory TYPE in the memory 5. FIG. 10 is a diagram showing an example of the chord pattern table, which is stored in the program memory 4 in advance, for example. For example, when the memory CHR2 () of FIG. 7 is compared with the chord pattern table of FIG. 10, since “augM7” matches the TYPE number of 10 in the chord pattern table, “10” is stored in the memory TYPE. Is stored.

In the following step S18, step S17
In, it is determined whether or not the input chord matches the chord pattern table. If the chord type is detected, that is, if the chord pattern table matches, the process proceeds to step S19 and the display 9 is displayed. , Displays the detected chord name. At this time, the input chord is not always displayed as it is on the display 9,
The chord converted by the character conversion process is displayed.
Therefore, the operator can know that the input chord has another notation and that the input chord is substituted by another chord.

Further, in step S20, the contents of the memory ROOT and memory TYPE are stored in the memory CPM (CP) and the next memory CPM (CP + 1) indicated by the pointer CP, respectively, and step S2 is executed.
With 1, the pointer CP is advanced by 2. Where the memory CP
M (CP) (CP = 0, 1, ...) is a chord progression memory 6
When the chord is input and the root and the type of the chord are determined, the root and the type are stored in order from the smallest number in the memory CPM (CP). The pointer CP plays a role in determining the position of the memory CPM (CP) that stores the root and type of the chord.

In a succeeding step S22, it is determined whether or not the input of the chord is finished. When the operator wants to finish the input of the chord, the operator presses a confirmation key (not shown) to notify the CPU 3 that the input of the chord is finished. . That is, when the confirmation key is pressed, the answer is affirmative (YES) in the determination routine of step S22, so the chord input processing is terminated, and if the confirmation key is not pressed, the procedure returns to step S12 and the next chord input is performed. Wait until there is.

On the other hand, if the chord type is not detected in step S18, the process proceeds to step S23, an error is displayed on the display 9, and the process proceeds to step S22.

As described above, the operator inputs almost all chords written on the musical score, that is, the same chord having a different notation or a chord that cannot be processed by this apparatus but can be substituted by another chord. In particular, even an operator who is not very familiar with musical scores can input chords described in various display methods on the musical scores.

In the present embodiment, only the chord input, which is a feature of the present invention, has been described, but it goes without saying that single-tone input can be performed simultaneously with chord input.

[0034]

As described above, according to the present invention,
If the chord name input by the chord name input means is not written in a predetermined notation, or is a chord that cannot be interpreted and can be substituted by another chord, the conversion means respectively determines Since it is converted into a notation or another chord that can be processed, it is possible to input a chord with a different notation or a chord that cannot be processed. In addition, since it is possible to accept chord names in multiple notations, even an operator who does not have much knowledge of the musical score may be having trouble inputting the chord name on the musical score. Less.
