[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a performance pattern processing apparatus, a performance pattern processing program recording medium, and a performance pattern data recording medium for performing processing such as display and selection of performance patterns.
[0002]
[Prior art]
A sequencer that can generate performance data using a fixed performance pattern independent of chords and the scale (scale) of the chord data is called a “code sequencer” or “pattern sequencer”. The performance pattern information includes the position (timing) and length of the note, the pitch or the pitch position corresponding to the pitch (the first tone from the bottom, the second tone, etc., or the root tone, the third tone, 5 Information). The chord sequencer moves the pitch of the performance pattern to the sound on the scale determined by the chord, or converts the pitch position information according to the pitch to the pitch above the scale, and finally By determining a specific pitch, the note data is completed and arranged in accordance with the position of the chord section, thereby completing the entire performance data.
[0003]
In such a chord sequencer, when selecting a pattern that is characteristic of performance data, the pattern data usually has a file name or pattern name as the main display, so it is difficult to understand what pattern it is. is there. Even if categories are classified by genre or the like, it becomes difficult to select a pattern when the number of categories and the patterns in the categories increase. Even with the same 4-time signature, the triplet pattern has a sense of incongruity with the usual 4-time melody, but it may be difficult to judge. Since the selected pattern string is displayed by name, it is difficult to determine which pattern is assigned to each section of the song. And so on.
[0004]
In addition, when trying to create musical score data of a specific instrument using the function of the chord sequencer, there is a problem that it is difficult to select a pattern that suits the user because the difficulty level is difficult to understand.

[0015]
[Effects of the Invention]
According to the first aspect of the present invention (claims 1 and 15), a plurality of pattern data is stored in the pattern data storage means (2, 4), and a list (LP) of the plurality of pattern data is stored in the code sequencer. When selecting a performance pattern displayed on the performance pattern selection screen (FIG. 6), when pattern data is designated from the pattern list (LP), the designated pattern data is read from the storage means, and the read pattern Simple graphic data is generated based on the data, and based on the generated simple schematic data, the pattern (CP) of the pattern in which the movement of the notes is converted into a simple graphic (chart) is displayed on the performance pattern selection screen [ FIG. 3 (A)]. Note that the parenthesis is a corresponding term or symbol used in an embodiment to be described in detail later for convenience of understanding, and the same applies to the following.
[0016]
According to the second feature of the present invention (claims 2 and 16), a plurality of pattern data is stored in the pattern data storage means (2, 4) together with simplified graphical data corresponding to each pattern data. When selecting a performance pattern by displaying a list (LP) of a plurality of pattern data on the performance pattern selection screen (FIG. 6) of the chord sequencer, it is instructed if the pattern data is instructed from the pattern list (LP). Simple graphic data corresponding to the pattern data is read from the storage means, and based on the read simple graphic data, the pattern pattern (CP) in which the movement of the notes is converted into a simple graphic (chart) is displayed as a performance pattern selection screen. It is displayed on the top [FIG. 3 (B)].
[0017]
That is, in the performance pattern processing according to the first or second feature, the simplified graphical data generated from the pattern data stored in the pattern data storage means (2, 4) or the pattern data storage means (2, 4). Based on the simplified graphic data stored together with the pattern data, the simplified graphic of the pattern (CP) is a simplified graphic of the performance pattern (movement of notes) of the pattern data selectively instructed using the list (LP). The pattern is displayed on the performance pattern selection screen as one piece of pattern data list selectable from the list (LP). Therefore, according to the present invention, it is possible to check the movement of a musical note with a simplified schematic picture instead of a word such as a pattern name, and the burden at the time of pattern selection can be reduced.
[0018]
In the performance pattern processing apparatus according to the first and second features (claims 1 and 2), the pattern data can hold a plurality of variation patterns. When a certain pattern data is designated, the variation pattern of the pattern data is stored. A simplified graphical pattern (pattern chart CP) corresponding to one variation pattern (referred to as “representative pattern” or “basic pattern”) designated in advance is displayed on the performance pattern selection screen of the chord sequencer. [Claim 3]. In other words, with this configuration, one of a plurality of variation data held in one pattern data is designated as a representative (basic) pattern, and a simplified diagram of the variation data designated as the representative (basic) pattern Can be displayed.
[0019]
Style data, which is a typical example of pattern data, can have multiple variations (intro, main, fill-in, ending, etc.) in one pattern data, but it is difficult to display all of these variations in advance. The chart of the representative (basic) pattern that has been decided is displayed. The style data usually has a multi-part configuration, and all the parts may be displayed. However, it is better to display only a predetermined part of the chart as a chart. For example, a piano part or the like is selected according to a tone color, or a part having a characteristic pattern is designated or detected in advance, or a part is selected according to the number of notes.
[0020]
Further, in the performance pattern processing device according to the first and second features (claims 1 and 2), the pattern data is selected from the pattern data storage means based on the specified selection information, and the selected pattern data is stored. A list can be displayed (claim 4). The basic concept of this configuration is that desired selection information [BG (CG), BM (CM), BT, BD, BS] can be input to a plurality of pattern data stored in the pattern data storage means. The pattern data is selected based on the input selection information, and the selected pattern data is displayed on the performance pattern selection screen of the chord sequencer. In other words, the selection target pattern is displayed based on the selection information for selecting the pattern to be displayed as the selection target. The purpose is to use a “pattern selection filter” function for selecting and restricting.
[0021]
For example, a time signature selection function can be created to select various time signatures [BM (CM)], and if only “4/4” is selected, patterns created with other time signatures are displayed. Not selectable. Using the idea of this “pattern selection filter”, in addition to the time signature, as will be described later, the type of “accompaniment” and “Arpeggio” [BG (CG)], “Triple” (BT), “Difficulty” "(BD)", "Combination type (scale)" (BS), etc. can also be selected.
[0022]
Furthermore, the idea of the pattern selection filter is further developed, and the pattern displayed on the performance pattern selection screen of the chord sequencer that can specify the range for creating performance data in advance by providing an automatic selection filter function for performance pattern selection. The data can be selected based on selection information corresponding to the input item information and corresponding to the musical condition of the performance data creation range. That is, if “automatic” is prepared as a selection filter selection option and “automatic” is selected there, only selection information that matches the musical condition of the performance data creation range is turned on. For example, when “automatic” is selected in the time signature filter (WM), if the time signature of the performance data creation range is “4/4”, only “4/4” pattern data is displayed. When a plurality of time signatures are mixed, all the time signatures are targeted, or the most time signature is targeted (FIG. 11).
[0023]
Further, in the performance pattern processing apparatus according to the first and second features (claims 1 and 2), the plurality of pattern data is triplet information (“triple flag” indicating whether or not the pattern data is a triplet pattern. ”) And the pattern data is read from the pattern data storage means, the content of the triplet information of the read pattern data is determined, and based on the determination result, the pattern data is a triplet pattern. It can be configured that whether or not there is displayed on the chord sequencer performance pattern selection screen (FIG. 6). In this way, by giving the performance pattern data indicating whether or not it is a triplet system, it is possible to clearly determine the triplet pattern.
[0024]
Alternatively, the difficulty level value can be given to the pattern data. In other words, the “difficulty level when playing” is recorded as a part of the pattern data, and the difficulty level can be displayed on the performance pattern selection screen (FIG. 6) of the chord sequencer. ]. With this configuration, the convenience of creating performance data can be further improved.
[0025]
According to the third aspect of the present invention (claims 8 and 17), the pattern data can have a plurality of variation patterns so that the pattern data has musical diversity. In other words, the combination type of variation patterns that can be held in one pattern is determined in advance, and a part of the pattern data is classified according to the number of variation patterns corresponding to the state of the combination type (= about the number of variation patterns) ) Is stored, and the scale of the variation is displayed by the scale information on the performance pattern selection screen of the chord sequencer so that the user can confirm the scale of the combination type. For example,
“Type 1” = Intro, Main A, Fill-in AA, Ending
“Type 2” = Intro, Main A, Main B, Fill-in AA, Fill-in AB, Fill-in BA, Fill-in BB, Ending
"Type 3" = Intro, Main A, Main B, Main C, ... Ending
In this way, it is easy to determine the scale of the variation that the pattern possesses by determining the combination type that combines the combinations of the variation patterns and displaying this type as scale information on the performance pattern selection screen. Be able to distinguish.
[0026]
In the performance pattern processing apparatus according to this feature (claim 8), it is effective to give names to the combination types and display them in order to have various combinations of variation patterns. In other words, a name is given to the combination type in advance (determined), and the combination type name information is stored as part of the pattern data as scale information, and this name is displayed on the performance pattern selection screen of the chord sequencer. [Claim 9] By configuring in this way, the user can confirm the combination type. In this case, for example, “Type 1” is “Small”, “Type 2” is “Medium”, and “Type 3” is “Large”. 6), it is possible to realize even easier understanding.
[0027]
When creating performance data, along with the difficulty level, the amount of change in the accompaniment also affects the sense of burden on the player, so give a name corresponding to the amount of change in the accompaniment as described above. Is also a preferred method. For example, if a device that automatically detects the position of the “main” or “fill-in” section and analyzes the “melody part” or “melody part + other part” and assigns the corresponding pattern is used, In the performance data created with “Type 1” and the data created with “Type 2”, “Type 2” has a greater burden on the user in terms of the range of change, but conversely, The bigger the change, the more fun it becomes. According to the present invention, the user can know such a situation in advance.
[0028]
According to the fourth aspect of the present invention (claims 10 and 18), when desired pattern data is sequentially selected from a plurality of pattern data and arranged in time series, the pattern sequence is created. Based on the pattern data that has been created, diagrammatic pattern sequence information is generated, and the pattern sequence that has been simplified diagrammatically corresponding to the generated pattern sequence information is fixed at a scale ratio in the pitch direction. Then, it is displayed on the track view screen (FIG. 13B).
[0029]
That is, a simplified diagram of the assigned pattern is displayed on the pattern row display portion of the track view screen that can sequentially display the pattern switching over time of the code sequencer. For example, when accompaniment data is formed by arranging multiple patterns, it is difficult to see what the data was when displaying only the name, but this simplifies mainly the movement of pattern notes When the picture is displayed on the accompaniment editing track (pattern row display section) in the track view, the data contents can be easily understood.
[0030]
In addition, when displaying the pattern image on the accompaniment editing track in the track view, the range after the pitch is changed by the chord becomes wider, so if you try to display it in the view part of the same vertical width, one note will be displayed. The vertical width that can be displayed is reduced, and depending on the pattern, it may be difficult to see whether the same thing is repeated. By fixing the scale ratio in the high direction (longitudinal direction), it can be easily confirmed later.
[0031]
In the performance pattern processing apparatus according to this feature (claim 10), when displaying a simplified pattern string in the track view, pattern string information having pitch data based on the pattern data selected at the time of pattern generation is generated, By configuring so that the pattern string is displayed at a position corresponding to the pitch data of the generated pattern string information, the scale ratio in the pitch direction (vertical direction) of the same pattern string is fixed. The In other words, the display mark corresponding to the note in the pattern is not the one after the pitch is determined by the chord, but the pitch of the pattern data or the information corresponding to it is kept, and the screen width in the vertical direction is one pattern. Since a constant scale ratio is maintained in the allocation range, the same pattern can be viewed as a series of the same display.
[0032]
According to the fifth aspect of the present invention (claims 12 and 19), a plurality of pattern data capable of holding accompaniment information indicating either a two-hand accompaniment or a left-hand accompaniment is prepared, and pattern data selection is performed. When a two-hand performance or a left-hand performance is input as information, it is determined whether the input selection information is a both-hand accompaniment or a left-hand accompaniment, and pattern data corresponding to the determined both-hand accompaniment or left-hand accompaniment from a plurality of pattern data Are selected, and the selected pattern data is displayed in a list. Then, desired pattern data is sequentially selected from the list-displayed pattern data, and performance data generation processing is performed from the selected pattern data.
[0033]
That is, a part of the pattern data in the piano accompaniment has information indicating whether the performance style is at least “both hands” or “left hand” as the performance style, and at least the performance styles are set to “two-hand accompaniment” and “ A function to select from “left-hand accompaniment” is given. When the two-hand accompaniment is selected, the pattern with the performance style of “two-handed” is displayed and selected. When the left-hand accompaniment is selected, the pattern of “left hand” is displayed and selected. In addition, piano accompaniment data generation processing is performed (FIG. 14), and “both-hand accompaniment” and “left-hand accompaniment” information of the piano accompaniment is generated.
[0034]
According to the sixth aspect of the present invention (claims 13 and 20), a plurality of pattern data capable of holding accompaniment information indicating either a two-hand accompaniment or a left-hand accompaniment is prepared and stored. When the desired pattern data is selected from the pattern data and the melody data is specified in advance in the piano accompaniment data generation process for generating performance data from the selected pattern data, the “left hand accompaniment” is used. The right-hand data processing is considered. That is, when the selected pattern data corresponds to the two-hand accompaniment, the accompaniment data (DBa) matching the specified chord is generated from the pattern data (PB) using the chord sequence function, and the pattern data The accompaniment data is converted into left-hand performance data (DRa = Dr) and right-hand performance data according to the conditions specified in the data, that is, according to the left / right designation (FIG. 15) or pitch split position (FIG. 16) in the pattern data. (DLa = DL), but when the selected pattern data corresponds to the left-hand accompaniment, the left-hand accompaniment data that matches the specified code using the chord sequence function from the pattern data (PL) (DLa) is generated and used as left-hand performance data (DL), and right-hand performance data is generated from melody data specified in advance. DRm = DR) for generating a.
[0035]
In the performance pattern processing apparatus according to these features (claims 12 and 13), the two-handed data (DR, DL) generated as described above is displayed on a score format screen, or a score format. (Claim 14).
[0036]
According to the seventh aspect of the present invention (claim 21), a plurality of pattern data is stored in the performance pattern data recording medium, and the pattern data is an accompaniment indicating either a two-hand accompaniment or a left-hand accompaniment. In addition to holding information, it is possible to hold a plurality of variation patterns and scale information indicating the scale of the variation by the number of variation patterns, triplet information indicating whether the pattern is a triplet pattern, It is possible to hold difficulty level information indicating the difficulty level when the pattern is played. Therefore, in performance pattern processing that creates pattern sequence data based on pattern data sequentially selected from a plurality of pattern data displayed in the pattern data list, it is effectively used according to various selections including both-hand accompaniment and left-hand accompaniment. Pattern data that can be provided can be provided.
[0037]

Can do. FIG. 1 illustrates a system using a personal computer (PC). However, an electronic musical instrument having a dedicated performance operator or panel operator is used, or another apparatus having an equivalent processing function is used. A performance pattern processing system may be configured.
[0049]
[Pattern data and performance pattern]
The performance pattern processing system according to one embodiment of the present invention is devised so that an outline of a performance pattern can be displayed using pattern data and a desired performance pattern can be easily selected. FIG. 2 shows a configuration example of pattern data used in the performance pattern processing system according to one embodiment of the present invention.
[0050]
A large number of pattern data is prepared in advance in the ROM 2 or the external storage device 4 of this system. FIG. 2 shows (A) “two-hand accompaniment 1”, (B) “left-hand accompaniment 1”, and (C) “two-handed”. As shown by “Accompaniment 2”, (D) “Both-hand accompaniment 3”,..., These pattern data are given pattern names. These pattern data include pattern data simply named “Pattern 1”, “Pattern 2”, etc. For example, there are groups named “Both-hand accompaniment”, “Left-hand accompaniment”, “Arpeggio”, etc. is there.
[0051]
Such pattern data belonging to a group can be distinguished from the group to which the pattern data belongs by identification data such as a group name or a group flag. For example, an accompaniment pattern of a piano has information indicating whether it is at least “both hands” or “left hand” as indicated by the pattern name “two-hand accompaniment” or “left-hand accompaniment”.
[0052]
The pattern data can also be composed of multiple variations of performance patterns ("variation patterns"). These variation patterns are accompaniment pattern data belonging to groups such as "two-hand accompaniment" and "left-hand accompaniment". As shown in the figure, one or more are set for each of the intro, main, fill-in (“fill” in the figure) and ending sections. The pattern data also includes arpeggio pattern data (not shown) belonging to the “Arpeggio” group. Like the accompaniment pattern data, each pattern data is “Arpeggio 1”, “Arpeggio 2”,. A pattern name is given and it can be composed of a plurality of variation patterns.
[0053]
Which of a plurality of variation patterns of each pattern data is a basic performance pattern (referred to as “representative pattern” or “basic pattern”) in the pattern data is set with a representative (basic) pattern flag or the like. , Can be set in advance. The representative (basic) pattern set in this way is shown by hatching in FIG. 2, and when the pattern data is displayed and selected from the pattern list (LP) displayed on the pattern selection screen of the display 12. As a performance pattern representing the pattern data, it is used to display a simple diagram called a “pattern chart” on the screen.
[0054]
FIG. 3 shows an example of such a simplified graphical display method. In the example of FIG. 3 (A), the timing information and pitch information of the note event are extracted from the performance pattern data, and the simplified diagram generation means generates simplified diagram data based on these information. It is displayed on the screen of the display 12. In the method of FIG. 3B, graphic data representing a pattern of note event sequences arranged in accordance with the timing and pitch of the performance pattern is created in advance, attached to the performance pattern data, and the pattern is selected. Then, a simple diagram based on the diagram data is displayed on the screen of the display 12.
[0055]
Each pattern data (two-handed accompaniment 1, left-handed accompaniment 1, two-handed accompaniment 2, two-handed accompaniment 3,...) Is added with information indicating a time signature (not shown). The information (not shown) indicating is also added with a flag called “triple flag”, for example. For the triplet information, it is only necessary to set the triplet flag to the “ON” state for the pattern data in the triplet system and to set the other patterns to the “OFF” state when creating the pattern data.
[0056]
In addition to the data described above, each pattern data includes information indicating the difficulty level of the pattern, the scale of variation, etc., as represented by “difficulty level” and “scale” in FIG. Performance advice data can be embedded.
[0057]
“Difficulty” records “difficulty when playing” as part of the pattern data, and this difficulty is displayed on the performance pattern selection screen of the chord sequencer for convenience in creating performance data. It is intended to give. In the illustrated example, with respect to the “difficulty”, the simplest one is “0” (displayed as “E” on the screen), and the most difficult one is “4” (displayed as “A”). ”To“ 4 ”(“ E ”,“ D ”,...,“ A ”).
[0058]
“Scale” is data indicating the scale of variation. In the example shown in the figure, in the case of an accompaniment pattern, one main section has a scale of “0” (displayed as “Small” on the screen), and two main sections have a scale of “1” (“Medium”). Display), and the main section has three scales “2” (indicated by “Large”). In the case of an arpeggio pattern, the scale is similarly divided according to the number of variation patterns. The number of patterns corresponding to the scale of the performance pattern is managed by the “scale” data.
[0059]
“Performance advice” information added to each pattern data is information in which advice instruction information is written for a performance pattern included in the pattern data. FIG. 4 shows an example of advice information embedded in the pattern data in this way. In FIG. 4A, advice information instructing to “play rhythmically as a whole and accent the fifth note 5” is added to the performance pattern of the intro section in the pattern data of the pattern name “pattern 1”. Has been. Also, in FIG. 4B, advice information instructing to “play smoothly overall” is added to the performance pattern of the intro section in the pattern data of the pattern name “pattern 1”.
[0060]
The advice information is added to the advice information, such as “overall” and “fifth note” described above, which indicates the performance location to be advised. Therefore, when generating performance data by the chord sequence function, advice information written in the performance pattern used for the performance data is displayed on the performance data display screen or printed on paper (score). In addition, since it is arranged at the optimum position according to the advice target information, it is possible to appropriately give advice to the user.
[0061]
FIG. 5 shows an example of a performance pattern data format usable in the performance pattern processing system according to the embodiment of the present invention. In each performance pattern constituting the pattern data, in the example of FIG. 5A, “timing” data and “note event” representing the pitch are repeatedly recorded. Here, the pitch of the “note event” is created based on a predetermined chord (for example, “Cmaj” or the like). For example, a pitch intended for a predetermined chord “Cmaj” is represented by a note number (for example, “C3”-“E3”-“G3”-“E3”, etc.). Therefore, in this data format, the pitch of the note event is corrected so as to match the chord designated by the chord sequencer according to the timing data, and is output.
[0062]
In the example of FIG. 5B, the performance pattern is a record in which “note event” represented by “timing” data and a number is repeatedly recorded, and the “note event” number is designated by a chord sequencer. One of the chord constituent sounds determined by the chord is designated. For example, number “1” = lowest sound, number “2” = second lowest sound (in the above example in “Cmaj”, “1” − “2” − “3” − “2”), etc. It is specified. Therefore, in this data format, the sound specified by the note event number is output according to the timing data.
[0063]
In the example of FIG. 5C, the performance pattern is a record in which “note event” represented by “timing” data and pitch is repeatedly recorded, and the pitch of “note event” is designated by the chord sequencer. It shows the sound of the pitch with respect to the root of the chord constituent sound (or the available note scale sound determined by the chord). For example, “1 degree”, “3 degrees”, “5 degrees” (“1 degree” − “3 degrees” − “5 degrees” − “3 degrees” in the above example in “Cmaj”), etc. , Indicated by the pitch relative to the root note. Therefore, in this data format, a sound indicated by the pitch of the note event is output based on the timing data.
[0064]
[Performance pattern selection screen]
FIG. 6 shows an example of a pattern selection screen displayed on the display in the performance pattern processing system according to one embodiment of the present invention. In this system, in the performance pattern selection mode of the chord sequencer, a pattern selection screen having a display format as shown in FIG. In the performance pattern processing system according to one embodiment of the present invention, a plurality of pattern data is displayed as a list LP on the display 12, and desired pattern data (each line: two-hand accompaniment 1, 2, 3, left-hand accompaniment 1, 2, arpeggio). 1,... Is indicated with the cursor CR, a diagrammatic pattern corresponding to the pattern data is displayed on the chart display unit CP. Each pattern data can have a plurality of variation patterns (intro, main A, main B, fill-in AA,...), And one representative (basic) pattern pattern designated from within the variation pattern is displayed on the display unit CP. Is displayed. By operating various selection buttons BG to BS on the right side of the screen, the pattern data corresponding to the operation item can be selected and displayed.
[0065]
That is, on the screen of FIG. 6, a pattern list LP for developing pattern data summary information (pattern information) and a pattern chart CP for developing a simplified diagram of a representative (basic) pattern corresponding to the pattern designated by the cursor CR. In addition to the above, a “accompaniment style selection” button BG for selecting a pattern group, a “time signature selection” button BM for selecting a pattern of a predetermined time signature, and a pattern selected with the cursor CR for further checking a variation pattern Various buttons such as a “variation” button BV are displayed.
[0066]
A desired pattern can be selected from the pattern list LP by operating the cursor button on the right end of the pattern list LP to move the cursor CR. The pattern information selected by the cursor CR is highlighted, and a simple diagram corresponding to the selected pattern is displayed in the pattern chart CP. Further, when the “accompaniment style selection” button BS is operated, the accompaniment style selection window (WS) is opened, and when the “time signature selection” button BM is operated, the time signature selection window (WM) is opened.
[0067]
[Performance pattern processing]
7 and 8 are flow charts showing performance pattern processing according to one embodiment of the present invention. When the performance pattern processing is started by operating the operator of the operator device 11, the system enters the performance pattern selection mode. In the first step S1, a predetermined pattern list LP is displayed on the display 12 as shown in FIG. Displayed on the pattern selection screen. That is, the pattern information initially displayed in the pattern list LP can be arbitrarily set. In the example of FIG. 6, information on patterns having all accompaniment styles and all time signatures is displayed in the pattern list LP. Is set to
[0068]
The items of pattern information displayed in the pattern list LP are, for example, “pattern name”, “time signature”, “triple (system)”, “difficulty”, and “scale”, and pattern data (FIG. 2). Displayed according to the contents of. For example, in the item column of “triple (system)”, data indicating a triplet pattern is displayed according to the triple flag of the pattern data set to “ON”. In the example of FIG. 6, it is indicated by a triplet system mark “*”. In addition, these items are also sorting information for sorting patterns, thereby obtaining the function of “pattern sorting filter”, and the patterns displayed in the pattern list LP on the pattern selection screen as selectable targets. It can be effectively limited.
[0069]
In the next step S2, a predetermined performance pattern of the pattern data indicated by the cursor CR is selected by default, and a simple diagram corresponding to the selected performance pattern is displayed in the pattern chart display area CP. The predetermined performance pattern selected as a default can be selected in advance as a representative (basic) pattern as described above. In the pattern selection screen of FIG. 6, a simple diagram based on the representative (basic) pattern set in the pattern data of the pattern name “Arpeggio 1” indicated by the cursor CR is displayed in the pattern chart display area CP. .
[0070]
Next, in step S3, it is determined whether or not a time signature has been selected by operating the “time signature selection” button BM. If there is “time signature selection”, a time signature selection window (dialog box) as shown in FIG. WM is opened. As shown in FIG. 9, a plurality of time signature options are displayed in this time signature selection window WM, and any one of these can be selected by instructing to click the time signature selection check button CM at the left end.
[0071]
Subsequently, in step S4, it is further determined whether or not the “time selection” check button CM (FIG. 9) “automatic selection” is selected and the time signature is automatically selected. Here, when the “automatic” time signature is selected, the time signature is automatically determined with reference to the code sequencer in step S5 (automatic selection filter), and then the process proceeds to step S7.
[0072]
When the time signature selection is set to “automatic” as described above, the time signature in the performance data generation section is examined by the processing program on the pattern selection screen, and the time signature is automatically determined according to the time signature distribution. Examples of such an automatic pattern selection method include the following methods:
(1) Display performance pattern information of all time signatures existing in the performance data generation section in the pattern list LP.
(2) The performance pattern information is displayed on the pattern list LP for the longest (most) time signature in the performance data generation section.
[0073]
For example, in a song in which time signatures are arranged as shown in FIG. 10, when 8 bars in the “performance data generation section” shown in FIG. 10 are selected for performance pattern selection, 7 bars out of 8 bars are “4/4”. Yes, the remaining one measure is “3/4”. In such a case, when the selection method of (1) is adopted, all time signatures existing in this section, that is, performance patterns of “4/4” and “3/4” are automatically selected. In the method (2), “4/4” which is the longest (most) time signature is selected. Therefore, for example, if the method (2) is adopted as the automatic selection method, the pattern list PL as shown in FIG. 11 is displayed when the “both-hand accompaniment” group has already been selected.
[0074]
On the other hand, if the time signature is set to other than “automatic”, the process proceeds from step S4 to step S6, the time specified by the time signature selection check button CM is determined, and then the process proceeds to step S7. In step S7, only the performance pattern information of the time signature determined in steps S5 and S6 is displayed as a list as a pattern list LP. For example, when “display all” is already selected for the accompaniment style and “display all” is selected also in the time signature selection window WM of FIG. 9, a pattern list like the pattern selection screen of FIG. LP is displayed. When “Both-hand accompaniment” is selected as the accompaniment style and “Display time signature = 4/4” is selected in the time signature selection window WM, the pattern list LP is displayed as shown in FIG.
[0075]
As described above, in Steps S3 to S7, the pattern selection filter function related to the time signature can limit the patterns displayed as pattern selection targets by the selection information of each item. Now, after performing the process of displaying a list of patterns selected in step S7, or when it is determined in step S3 that no time signature is selected, the process proceeds to step S8.
[0076]
In step S8, “other filter function processing” for selecting pattern data displayed in the pattern list LP is executed in accordance with various operations for selecting performance data for various items other than the time signature. As already described (steps S3 to S7), the time signature is created with the selected time signature by operating the time signature selection button BM and the time signature selection window WM (FIG. 9) to select a time signature. Only the existing patterns can be displayed. In the pattern list LP of the pattern selection screen, for example, as shown in FIG. 6, in addition to “time signature”, “pattern name”, “triple (system)”, “difficulty”, “scale”, etc. By specifying these items, the pattern data displayed in the pattern list LP can be selected as in the case of the time signature.
[0077]
“Pattern name” includes the name of the pattern group to which the pattern belongs (for example, “Left-handed accompaniment”, “Both-handed accompaniment”, “Arpeggio”, etc.), and operates the “Accompaniment style selection” button BG on the pattern selection screen. By doing so, a desired pattern group can be selected. That is, when the accompaniment style selection button BG is operated on the pattern selection screen shown in FIG. 6, an accompaniment style selection window (dialog box) WG as shown in FIG. 12 is opened, and a plurality of pattern group options are displayed. . Here, by instructing to click the accompaniment style selection check button CG at the left end, a pattern group corresponding to the instruction of the button CG can be selected from these options.
[0078]
When the “OK” button BK is operated, information on the pattern group belonging to the selected pattern group is displayed in the pattern list LP on the pattern selection screen. For example, when “display all” is already selected in the time signature selection window WM in FIG. 9 and “display all” is selected in the accompaniment style selection window WG in FIG. 12, the pattern selection in FIG. Although it is displayed as a pattern list LP on the screen, when “Display time = 4/4” is selected in the time signature selection window WM and “Both-hand accompaniment” is selected in the accompaniment style selection window WG, The display is as shown in FIG. If the “Cancel” button BC is operated, the original pattern selection screen is restored.
[0079]
On the pattern selection screen, the piano performance style can be selected from either “two-handed accompaniment” or “left-handed accompaniment”. When “two-handed accompaniment” is selected, the performance belonging to “two-handed accompaniment” Patterns that are styles are displayed in the pattern list LP, from which performance patterns can be selected. Further, when “left hand accompaniment” is selected, a pattern that is “left hand” is displayed and a performance pattern can be selected.
[0080]
For example, when “both-hand accompaniment” is selected in the accompaniment style selection window WG (FIG. 12), “two-hand accompaniment 1”, “two-hand accompaniment 2”, “ A pattern of two-hand accompaniment 3 ”,... Is displayed. When “left hand accompaniment” is selected, patterns of “left hand accompaniment 1”, “left hand accompaniment 2”,... Are displayed.
[0081]
Similarly, for “triplet (system)”, a triplet (system) pattern can be displayed by operating the “triple system extraction” button BT. In this case, every time the button BT is operated, the extraction and display of the triplet (system) pattern information and the original pattern display are repeated.
[0082]
Further, regarding the “difficulty level” and “scale (combination type)”, when the difficulty level selection button BD or the “combination scale selection” button BS is operated, the difficulty level selection window having the same format as the accompaniment style selection window WG in FIG. Alternatively, a combination scale selection window is opened. By selecting a desired difficulty level or scale from these windows, pattern information corresponding to this selection is displayed in the pattern list LP of the pattern selection screen.
[0083]
If necessary, other item information can be provided in each pattern data, and the idea of such a pattern selection filter function can be used.
[0084]
In the pattern selection screen, the user can select and select desired pattern data by operating the cursor buttons and moving the cursor CR up and down for the pattern information of each line displayed in the pattern list LP. The pattern rows are highlighted as shown in FIG. 6 and FIG. When a plurality of performance patterns (variation patterns) are set in the selected pattern data, the variation button BV is further operated to call a variation pattern display window (not shown), and a performance pattern selection button (not shown) is displayed. ) To display each variation pattern, and a desired performance pattern can be selected from these.
[0085]
In the next step S9, it is determined whether or not various operations for performance pattern selection (excluding time signature selection operations) as described above have been performed. If such operations have been performed (YES), step S9 is performed. Proceeding to S10 (FIG. 8), a process of displaying a simplified diagram corresponding to the selected performance pattern is performed. In step S10, the simplified pattern of the performance pattern is the representative (basic) pattern method already described in FIG. 3 when the pattern data selected / instructed by the cursor CR includes a plurality of performance data (variation data). When the pattern data selected / indicated with the cursor CR has only one performance data, or when a desired performance pattern is selected / indicated in the variation pattern display window, a diagram corresponding to the content of the performance pattern is shown in FIG. 6 is displayed like a pattern shown in the pattern chart display area CP.
[0086]
After the process of displaying the simplified schematic in step S10, or when a negative (NO) determination is made in step S9, whether or not there has been an operation (not shown) for confirming the selected performance pattern in step S11. Is determined. If there is a confirming operation and an affirmative (YES) determination is made, the selected performance pattern is recorded in the chord sequencer in step S12. In step S13, a simplified diagram of the pattern sequence is displayed on the display 12.
[0087]
In other words, the code sequencer pattern corresponding to the passage of time can be sequentially switched and displayed on a screen called a “track view screen”. In this step S13, a pattern row display section provided on the track view screen is displayed. In the (accompaniment edit track), a simplified diagram of the pattern assigned by selecting the performance pattern is displayed. As described above, according to one embodiment of the present invention, a simplified diagram is displayed on the accompaniment editing track in the track view by the process of displaying the pattern sequence in a simplified diagram, centering on the movement of the pattern notes and the like. Therefore, for example, when accompaniment data is formed by arranging a plurality of patterns, the contents of each data can be easily understood.
[0088]
FIG. 13 shows an example of displaying such a pattern sequence in a simplified diagram. FIG. 13B shows a track view screen including a bar number, a melody pattern string, a chord, and an accompaniment pattern string display section. Information and patterns associated with the progression of music (elapsed time) are sequentially displayed. It can be displayed by scrolling left and right on the display unit. In each of the pattern row display portions, each note mark indicating a note (note) pattern has a length in the horizontal (left and right) direction representing the note length, and an arrangement position in the vertical (up and down) direction represents a pitch.
[0089]
FIG. 13A exemplifies a pattern unit in which accompaniment data for one measure of a selected performance pattern is diagrammed. When the accompaniment pattern of FIG. 13A is assigned to the 14th bar and the 15th bar, and another accompaniment pattern unit is assigned to the 16th bar, the pattern sequence is as shown in the accompaniment pattern string display section of FIG. A simplified diagram of is displayed. That is, the simplified pattern sequence illustrated in FIG. 13B is obtained by pasting the pattern display for one bar as shown in FIG. 13A with reference to the head position of the code section. In the example of FIG. 13B, it can be easily seen that the 14th bar and the 15th bar of different chords (G # m, C #) have the same simplified diagram and have the same accompaniment pattern according to the pattern design. On the other hand, it can be easily seen that the sixteenth measure is a display of a different pattern from the fourteenth and fifteenth measures.
[0090]
In one embodiment of the present invention, when a simplified schematic pattern string is displayed in the track view, note marks corresponding to notes (notes) inside the pattern are those after the pitch is determined by the chord. Instead, the position corresponding to the pitch of the pattern data itself, or information according to the position is used. As a result, the vertical screen width of the pattern row display can maintain a constant scale ratio in one pattern allocation range, and the same pattern can be viewed as a series of the same display.
[0091]
That is, when displaying the pattern picture on the pattern view display section (accompaniment editing track) in the track view, the pitch range is changed by the chord, so the range of the same accompaniment pattern becomes wider. If you try to display it in a part, you can display one note, but the vertical width is small, or depending on the pattern, it may be difficult to see whether the same thing is repeated, but as described above, the plain original pattern before code development By continuously displaying and fixing the vertical scale ratio of the pattern row, it can be easily confirmed later.
[0092]
Now, after the simplified schematic display process of the pattern sequence in step S13 or after the negative (NO) determination in step S11, the process proceeds to step S14. In step S14, it is determined whether or not an operation for instructing reproduction, score display, or score printing has been performed on the performance pattern recorded in the chord sequencer. If any of the instruction operations has been performed, a step subsequent to the processing in step S15 is performed. The process proceeds to S16, and if not, the process immediately proceeds to Step S16.
[0093]
In step S15, the performance pattern recorded in the chord sequencer is developed to generate predetermined performance data, and reproduction, score display or score printing is performed according to the contents of the instruction. Here, in one embodiment of the present invention, when melody data is designated in advance and the “both-hand accompaniment” or “left-hand accompaniment” pattern is selected, as shown in FIG. ”Or“ Left-hand accompaniment ”, different processing is performed.
[0094]
For example, when the performance data generation is executed by selecting the “two-hand accompaniment” pattern, the chord progression data and the pattern sequence dedicated to both hands of the pattern sequence (as shown on the right side of FIG. 14) are used. A two-hand accompaniment data DBa is generated from the two-hand accompaniment pattern) PB. Then, the generated both-hand accompaniment data DBa is separated into left and right accompaniment data DLa and right-hand accompaniment data DRa under the conditions specified in the pattern sequence data, and is set as left-hand performance data DL and right-hand performance data DR, respectively. The
[0095]
On the other hand, when the performance data is generated when the “left-hand accompaniment” pattern is selected, the chord progression data and the left-hand dedicated performance pattern of the pattern sequence are utilized using the chord sequence function as shown on the left side of FIG. (Left-hand accompaniment pattern) Left-hand accompaniment data DLa is generated from PL and used as left-hand performance (accompaniment) data DL. Further, for the processing of the right hand data in the “left hand accompaniment”, the melody data DRm designated in advance is used as the right hand performance data DR.
[0096]
The generated performance data DL and DR of both hands are reproduced via the musical tone generating means 8, 9, and 13 and displayed on the display 12 in a musical score format screen, or a printer (see FIG. (Not shown) and printed out in a score format.
[0097]
FIGS. 15 and 16 show performance data generated by the performance data generation process at the time of the “two-hand accompaniment” described above in a simplified manner with a pattern of one bar (horizontal axis). In both figures, the vertical axis represents data based on the pitch, and the white square represents each note (note). In the pattern of FIG. 15, “left hand” or “right hand” is designated for each note. For this reason, for example, the velocity value is set in advance so that an even velocity value has a left hand and an odd velocity value has a right hand. On the other hand, in the pattern of FIG. 16, the left and right can be distinguished by a predetermined pitch split position.
[0098]
In the performance data generation process in FIG. 14, the two-hand dedicated performance pattern (two-hand accompaniment pattern) has one of the above-mentioned data, and after the two-hand accompaniment data DBa is generated, the final pattern generated from the left hand notes is generated. The note data is inserted into the left hand performance (accompaniment) data DL, and the final note data generated from the right hand note is inserted into the right hand performance (accompaniment) data DR.
[0099]
When displaying or printing a score in step S15, if advice information is included in the performance pattern as described with reference to FIG. 4, the advice is also displayed or printed. That is, in this case, when performance data is generated using the chord sequence function by the processing of FIG. 14, the advice information written in the used performance pattern is displayed on the performance data display screen of the display 12 according to the target information. Along with the score, it is displayed or printed on a paper score with a printer.
[0100]
FIG. 17 shows an example of a score with advice created in correspondence with the advice information example of FIG. 4 and displayed or printed on a display or printer. In this example, the advice “Let's play rhythmically” in FIG. 4A is an advice for the entire “pattern 1”, so it is displayed at the start position of “pattern 1” according to the advice target information “whole” and is called “accent” The advice character string is added to the position indicating the fifth note of each “pattern 1” of the performance data according to the advice target information “note 5” representing the target to be played with “accent”. Also, the advice “Let's play smoothly” for “Pattern 2” in FIG. 4B is the third bar that is the switching position to “Pattern 2” and the fifth bar that is the first position that has been turned over. Is displayed.
[0101]
In step S16, it is determined whether or not an operation for ending this pattern selection process has been performed. If this operation has not been performed, the process proceeds to step S17 to perform "other processing". “Other processing” includes input of chord progression, input of melody, designation of performance pattern pasting position, etc. After “other processing”, the process returns to step S3, and steps S3 to S3 are performed until an end operation is performed. The process of S17 is repeated. Then, when an end operation is performed, the pattern selection process is ended.
[0102]
【The invention's effect】
As described above, according to the present invention, when pattern data is selectively instructed from a pattern list in which a plurality of pattern data is displayed, the instructed pattern data is read from the pattern data storage means and simplified from this pattern data. Graphic data is generated, or simple graphic data stored together with the designated pattern data is read from the pattern data storage means. Then, based on the simplified schematic data, a simplified schematic pattern of a picture that simply represents the movement of the note represented by the performance pattern of the instructed pattern data is displayed as one piece of pattern data list selectable from the pattern list Is done. Therefore, according to the present invention, only by instructing pattern data as a selection candidate using a pattern list, by displaying a pattern in which the movement of a note is simplified according to the instructed pattern data, The outline of the performance pattern instructed as the selection candidate can be easily confirmed.
[0103]
In this case, each pattern data can have a plurality of variation patterns, and is represented by a diagrammatic pattern (chart) corresponding to one predetermined basic data designated from these variation patterns (basic (basic)). ) It is displayed as a pattern. Therefore, by displaying a pattern (chart) that is a simplified diagram of the pattern as one piece of information in each row pattern data list in the pattern list, the pattern can be confirmed with a simplified diagram of the movement of notes. The burden of choice can be reduced. In addition, this method has a simple display process, and by selecting basic data according to an appropriate standard, a representative (basic) pattern according to needs can be obtained.
[0104]
Further, since the pattern data is selected from the pattern data storage means based on the specified selection information and the selected pattern data is displayed in a list, the plurality of pattern data stored in the pattern data storage means Thus, desired selection information can be input, pattern data is selected based on the input selection information, and the selected pattern data can be displayed on the performance pattern selection screen of the chord sequencer.
[0105]
Further, since desired pattern data is selected from a plurality of pattern data based on selection information corresponding to musical conditions in the performance data creation range, the selected pattern data is displayed. On the chord sequencer performance pattern selection screen where the performance data creation range can be specified, "Automatic" is prepared as a selection filter selection option. If "Automatic" is selected, the musical data in the performance data creation range Based on the selection information that matches the condition, the pattern data that satisfies the condition can be automatically selected.
[0106]
Also, as a performance pattern, a plurality of pattern data having triplet information (triplet flag) indicating whether or not a triplet system is stored is stored, and the content of the triplet information of each pattern data is determined. Based on this, whether or not the pattern is a triplet pattern is displayed on the performance pattern selection screen of the chord sequencer, thereby making it possible to clearly determine the triplet pattern. Alternatively, each of the plurality of pattern data has difficulty level information indicating a difficulty level value when playing with the pattern, and the content of the difficulty level information of each pattern data is determined, and the determined difficulty level is represented by a code sequencer. By displaying on the performance pattern selection screen, the convenience of creating performance data can be improved.
[0107]
According to the present invention, since the pattern data has a plurality of variation patterns and can be constituted by a combination of various variations, the pattern data has musical diversity and each pattern data Is provided with scale information indicating the scale of the variation combination by the number of variation patterns, and the scale of the variation corresponding to the contents of the scale information is displayed on the performance pattern selection screen of the chord sequencer. The scale of the variation combination can be confirmed.
[0108]
In this way, when displaying the scale of pattern data variations, it is possible to easily check the combination type by displaying the scale of the variation with the name of the character string and giving an easy-to-understand name to the scale of the combination type. And effective. In other words, when creating data for performance, along with the difficulty level, the amount of change in accompaniment also affects the sense of burden on the player, but the magnitude of the burden can be known in advance by a specific name. .
[0109]
According to the present invention, desired pattern data is sequentially selected from a plurality of pattern data and arranged in time series to create a pattern sequence, which is graphically represented based on the pattern data arranged in the created pattern sequence. Pattern sequence information is generated, and the pattern sequence corresponding to the generated pattern sequence information is displayed on the accompaniment editing track in the track view with the scale ratio in the pitch direction (vertical direction) fixed. Thus, the contents of the assigned performance data can be easily understood from the pictorial diagram in which the assigned pattern is simplified. In particular, by fixing the scale ratio in the pitch direction (vertical direction) of the same pattern sequence, a plain pattern before the chord development is continuously displayed, so that the same pattern can be viewed as a sequence of the same display.
[0110]
In this case, pattern sequence information having pitch data based on the selected pattern data is generated, and the pattern sequence is displayed at a position corresponding to the pitch data of the generated pattern sequence information. The scale ratio in the vertical direction is fixed. In other words, the mark in the pattern row corresponding to the notes in the pattern is not the one after the pitch is determined by the chord, but the pitch of the pattern data or information according to it is left as it is in the vertical direction. The screen width is maintained at a constant scale ratio within the range of one pattern assignment, and the same pattern can be viewed as a series of the same display.
[0111]
In this invention, when selection information is input to a plurality of pattern data that can hold accompaniment information indicating whether it is a two-hand accompaniment or a left-hand accompaniment, the input selection information is either a two-hand accompaniment or a left-hand accompaniment. Is determined, and pattern data corresponding to the determined both-hand accompaniment or left-hand accompaniment is selected from a plurality of pattern data. The selected pattern data is displayed as a list, and when desired pattern data is selected from the displayed pattern data, performance data is generated from the selected pattern data. Therefore, according to the present invention, a part of the pattern data in the piano accompaniment has information indicating whether the performance style is “both hands” or “left hand”, and the pattern selection screen displays “both hands accompaniment” or “ By making it possible to select the “Left-handed accompaniment” performance style, when a two-handed accompaniment is selected, the pattern with the performance style of “Both-handed” is displayed and selected, and the left-hand accompaniment is selected. In such a case, it is possible to perform piano accompaniment data generation processing after displaying and selecting a pattern that is “left hand”.
[0112]
According to this invention, it is based on the selected pattern data in response to selecting desired pattern data from a plurality of pattern data capable of holding accompaniment information indicating either a two-hand accompaniment or a left-hand accompaniment In the piano accompaniment data generation process for generating performance data, when corresponding to both-hand accompaniment, accompaniment data matching the specified chord is generated from the pattern data, and this is designated as the left / right designation or pitch in the pattern data. According to the split position, it can be separated into left hand performance data and right hand performance data. On the other hand, when the selected pattern data corresponds to the left-hand accompaniment, left-hand accompaniment data matching the specified chord is generated from the pattern data, and this is used as left-hand performance data and from the melody data specified in advance. Right hand performance data can be generated.
[0113]
The performance data generated in each of the piano accompaniment data generation processes described above can be displayed or printed out in a score format.
[0114]
According to the present invention, a plurality of pattern data are stored in the performance pattern data recording medium, and these pattern data have accompaniment information indicating either a two-hand accompaniment or a left-hand accompaniment and a plurality of variations. The scale information indicating the size of the variation can be held by the number of patterns and the number of variation patterns, and triplet information indicating whether the pattern is a triplet pattern or the difficulty level when playing the pattern.
