However, the dimensions, materials, shapes, and relative positions of components described in the following embodiments can be arbitrarily set, and can be changed according to the configuration of the apparatus to which the present invention is applied or various conditions. Also, unless otherwise stated, the scope of the invention is not limited to the embodiments specifically described below.

FIG. 1 shows a front view of a game machine 10, which is an example of a game system. This game machine 10 can play a predetermined game by consuming a predetermined price, for example. However, the game system of this embodiment may be a mobile phone, a tablet computer, a laptop computer, a desktop computer, a portable game machine, or a stationary game machine (for example, a home game machine). Furthermore, the game system is a system including a plurality of devices, such as a system including a game terminal and a server, and a system including an arcade game machine, a server, and a terminal device (for example, a portable terminal or a stationary terminal). good too. Also, the types of games provided by the game machine 10 may be games in which music is played during play, such as shooting games, racing games, role-playing games, fighting games, and the like. In the following description, unless otherwise specified, the game system is an arcade game machine and provides a music game.

The game machine 10 includes a housing unit 11 that houses a control unit 30 and a memory 40 (FIG. 3), a monitor 12 that is an example of a display unit that displays a game screen, and reproduces sounds such as music and effects. A speaker 13 is provided. An operation unit 14 is arranged on the upper surface of the housing unit 11 . The operation unit 14 includes a start button 15, four operation buttons 16, two effect buttons 17 operated to reproduce effects such as bass sounds and drum sounds, and two rotating devices capable of rotating. 18. The start button 15, the operation button 16, and the effect button 17 are operated by being pressed by the user. The rotating device 18 is operated by the user rotating it leftward or rightward in FIG. Alternatively, at least one of the monitor 12 , the speaker 13 and the operation unit 14 may be separate from the game machine 10 .

The start button 15 is used to start the game, select music, set the game difficulty level, and the like. When starting the game, the user operates the start button 15 according to the instructions on the start screen displayed on the monitor 12 . For example, the user selects various settings such as the song to play, the game mode, and the difficulty of the game. Also, the user can select a normal mode or a synthetic music mode from the game modes. When the normal mode is selected, the user plays the selected one or more songs individually. When the synthetic music mode is selected, the user selects multiple songs and plays the synthetic music created by the game machine 10 based on the selected multiple songs. Then, when the game is started, the user operates the operation button 16, the effect button 17, and the rotation device 18 according to the guidance of the operation procedure by the objects that move on the game screen.

FIG. 2 is an example of a game screen displayed on the monitor 12. As shown in FIG. At the bottom of the game screen, there is an image simulating the operation unit 14 of the game machine 10, and between the two images simulating the rotary device 18, there is an operation line 21 extending in the horizontal direction of the game screen. Six lanes 22 extend in the vertical direction of the game screen in a direction intersecting the operation line 21 . On these lanes 22, a normal object 23 on one lane 22, effect objects 24 on two lanes, and line objects 25 crossing a plurality of lanes 22 are displayed. These objects are displayed to guide the user through the operating procedure of the game. Then, each object moves from the upper part of the screen toward the operation line 21 in time with the music reproduced from the speaker 13 . The user operates the operation unit 14 at the timing when these objects reach the operation line 21 . Then, when the timing of the user's game operation and the arrival timing of the object match, the user's score is added. Also, if the two timings do not match, the user's score may be subtracted.

A normal object 23 corresponds to the operation button 16 and is displayed on one of the four lanes 22 . Then, the user presses down the corresponding operation button 16 at the timing when the normal object 23 reaches the operation line 21 . Also, the effect object 24 corresponds to the effect button 17 and is displayed across the two lanes 22, and the user can press the effect button 17 corresponding to the effect button 17 in accordance with the timing when the effect object 24 reaches the operation line 21. press down. When the timing when the user presses the effect button 17 coincides with the arrival timing of the effect object 24, the effect sound is reproduced from the speaker 13. - 特許庁

The line object 25 is displayed so as to cross each lane 22 in a range from one end lane 22 to the other end lane 22 of the left end and right end lanes 22 on the game screen. The line objects 25 are displayed in different colors, for example, so as to correspond to the rotating device 18 on the right side and the rotating device 18 on the left side, respectively. For example, a triangular operation sign (not shown) is displayed that moves in the horizontal direction on the operation line 21 so as to correspond to each line object 25 . These operation signs are also displayed in different colors, for example, so as to correspond to the left and right rotary devices 18, respectively. Then, for example, the user moves the line object 25 so that the horizontal position of the operation sign on the operation line 21 and the line object 25 coincide with the timing when the line object 25 on the rightmost lane 22 reaches the operation line 21 . , rotate the right rotation device 18 . Depending on the position where the line object 25 intersects the operation line 21, the right rotating device 18 is rotated leftward or rightward and operated. Since such an operation is the same for the left rotating device 18, the explanation is omitted. The position on the operation line 21 of the operation sign that moves within the screen by the user rotating the rotary device 18 and the intersection position of the line object 25 with the operation line 21 have a predetermined relationship (for example, within a predetermined range). ), a continuous effect sound is reproduced from the speaker 13 .

To the right of the plurality of lanes 22 is a score display section 26 that displays the score obtained by the user. A clear zone 27 is provided above the score display section 26, and a gauge 28 displaying the score obtained by the user approaches the clear zone 27 as the score is added. When the game ends with the gauge 28 reaching the clear zone 27, the game is cleared. Also, an icon 29 is displayed above the plurality of lanes 22 as an example of a specific display for specifying the song being played. For example, the icon 29 is an image that reminds the user of music, and the user who sees the icon 29 can identify the music being played. Furthermore, the icon 29 allows viewers other than the user viewing the game screen, for example, spectators watching around the user to identify the song being played. Note that the specific display may be various displays such as a music jacket image, characters such as a music title, colors, and graphics, as long as the display reminds the user of the music. A case where the icon 29 is displayed as the specific display will be described below.

When the game is started, the game screen is displayed on the monitor 12 and music is reproduced from the speaker 13 . Then, the user presses the operation button 16 and the effect button 17 according to the operation procedure displayed on the monitor 12, that is, the movement of the normal object 23 and the effect object 24, to play the game. At this time, when the user presses the effect button 17 , the effect sound is reproduced from the speaker 13 . Further, the user rotates the rotating device 18 to play the game according to the operation procedure displayed on the monitor 12 , that is, the movement of the line object 25 .

FIG. 3 is a block diagram showing the control section 30 inside the housing section 11. As shown in FIG. This control unit 30 functions as a computer of the game system and includes, as an example, a CPU, SPU, and GPU (not shown). Based on the programs stored in the memory 40, the control unit 30 controls the game machine 10 as a whole, and also controls various processes in a centralized manner. Also, the memory 40 is a computer-readable recording medium storing a control program 41 and a game program 42 . As an example, the memory 40 has a RAM that is a system work memory for the control unit 30 to operate, and a ROM and/or hard disk drive that stores the control program 41 and the game program 42 . The control unit 30 may be controlled according to a control program 41 and a game program 42 stored in an external computer-readable recording medium such as a CD (Compact Disc), USB memory, or server on the Internet.

The control unit 30 has a display control unit 50 that displays the game screen on the monitor 12 and a reproduction control unit 60 that causes the speaker 13 to reproduce music. The control unit 30 also has an operation evaluation unit 70 that evaluates the user's game operation input from the operation unit 14 and calculates a score, and a music creation unit 80 that selects sections constituting a synthesized music, which will be described later. are doing. Each unit is generated as a logical device in the control unit 30 and logically realized as various functions by the control unit 30 executing various processes corresponding to the game program 42 stored in the memory 40 . However, for convenience of explanation, the illustration of some logical devices is omitted.

The memory 40 stores game data 43 used in the game, such as image data such as icons 29, objects, and backgrounds, music data such as music, sound effects, and dramatic sounds, and sheet music data defining game operation procedures. and remember. The song data includes data corresponding to a plurality of songs each divided into a plurality of sections. Data corresponding to the plurality of songs are stored in a state divided into a plurality of sections. The musical score data is composed of data such as the type of object, the timing of operation, and the arrival position on the game screen, for example. This music score data is stored in a state divided into a plurality of sections for each piece of music, and the timing at which an object should be operated is stored, for example, as the elapsed time from the beginning of the section. The timing to be operated may be stored as an accumulated elapsed time from the beginning of the music, or may be stored as the number of beats from the beginning of the section or the number of beats from the beginning of the music. Storing the number of beats facilitates adjustment when the tempo during playback is changed. The song data may include data for each of a plurality of songs, and the musical score data may include a plurality of sets of data corresponding to the difficulty level for data of one song. The display control unit 50 causes the monitor 12 to display an image at a predetermined timing based on the image data and musical score data. Also, the reproduction control unit 60 causes the speaker 13 to reproduce sound based on the music data. Further, the reproduction control unit 60 causes the speaker 13 to reproduce the effect sound according to the user's game operation input from the operation unit 14 . At least part of the game data 43 may be stored in an external storage device.

As shown in FIG. 4, the operation evaluation section 70 includes a guidance section 71 that functions as guidance means for guiding the game user to the game operation procedure. The operation evaluation unit 70 also includes an evaluation unit 72 that evaluates the game operation based on the user's game operation input from the operation unit 14 . Specifically, the guiding unit 71 moves each object on the lane 22 at a predetermined timing and speed based on the musical score data. That is, the guide section 71 moves each object so that the object reaches the operation line 21 at a predetermined operation timing. In this way, the guide section 71 guides the user to the button or device of the operation section 14 that the user should operate and the operation timing thereof.

Based on the score data, the evaluation section 72 determines which button or device in the operation section 14 is the operation timing to be operated. This operation timing is set in the middle of the predetermined length of operation time. Then, the evaluation unit 72 detects the user's game operation on the button or device to be operated within the operation time. Furthermore, the evaluation unit 72 evaluates the user's operation based on the amount of deviation between the detected game operation and the operation timing. For example, when the evaluation unit 72 detects a game operation at the middle timing of the operation time (the deviation amount is zero), the evaluation unit 72 highly evaluates the user's operation and adds a high score.

Also, when the evaluation unit 72 detects a game operation at a slightly earlier or later timing than the middle of the operation time (the amount of deviation is small), the evaluation unit 72 normally evaluates the user's operation and adds a normal score. Furthermore, if the evaluation unit 72 detects the game operation at a timing that is significantly earlier or later than the middle of the operation time (the amount of deviation is large), or if the game operation is not detected within the operation time, the user has failed in the operation. Then, subtract or not add the score.

Then, the display control unit 50 displays an image showing the evaluation result by the evaluation unit 72 on the game screen. For example, the display control unit 50 displays the characters "CRITICAL" when adding a high score. In addition, the display control unit 50 displays the characters "NEAR" when adding the normal score. Furthermore, the display control unit 50 displays the characters "ERROR" when subtracting the score. Note that the display control unit 50 may display the score numerically together with the characters, or may display the total score on the game screen during the game.

Alternatively, the evaluation unit 72 may set the initial value of the score at the start of the game to the maximum value, and subtract the score when the user fails in the operation. In this case, the evaluation unit 72 may add the score when the user has successfully performed the operation. For example, if the gauge indicating the remaining score exceeds the clear zone 27 at the end of the game (at the end of playing music), the game is cleared.

[Creating synthetic music]
The music creation unit 80 of the control unit 30 selects at least two sections of music from music data including a plurality of sections obtained by dividing a plurality of music into a plurality of sections, and selects at least two sections of the music so that these sections are included. Create a synthetic music for The creation of synthetic music will be described below with reference to FIGS. 5 and 6. FIG.

As shown in FIG. 5A, a base song A, which is the basis of a synthesized song to be described later, is divided into six sections A1, A2, A3, A4, A5 and A6. Similarly, sub-music B, which is a composition synthesized with base music A, is divided into six sections B1, B2, B3, B4, B5 and B6. Each of the multiple sections is associated with reference information that is referenced to select preferred sections to be included in the synthesized music. For example, this reference information is placed in the header of each section's data or included in the song data in the form of a table associated with each section. As shown in FIG. 4, the music creation unit 80 includes a reproduction section selection unit 81 as reproduction section selection means for selecting at least two sections to be included in the synthesized music from the music data. Further, the music creation unit 80 includes a connection section selection unit 82 as connection section selection means for selecting a connection section to be positioned between priority sections from music data based on reference information.

As an example, the reference information includes configuration information indicating the position in the composition of the music as information indicating that the section is a priority section to be included in the synthesized music, and musical score indicating that the section is likely to be played by the user. contains information and Further, the reference information includes compatibility information for determining the compatibility of connections with other sections. This compatibility information further includes key information indicating the key of the entire section, chord information indicating the chord progression in the section, and attribute information referred to when creating the synthesized music. It should be noted that the music creation unit 80 may refer to the key information when creating the synthesized music, and change the keys of consecutive sections to be aligned. Furthermore, the music creation unit 80 may change the volume and tempo of consecutive sections to be the same when creating a synthesized music. These changes may be changes to suit either section, that is, changes to only one section, or changes to both sections. Alternatively, the music creating unit 80 may match at least one of the key, volume and tempo of the songs when creating the synthesized music. When there is a piece of music in which the key or the like changes in the middle of the piece of music, the change of the key or the like in the piece of music is maintained by uniformly changing the entire piece of music. When matching the key, volume and tempo, the music may be changed to match any song, or may be matched to a different key, volume and tempo.

The composition information indicates the composition of, for example, an intro, an A melody, a B melody, a chorus 1, an interlude, a chorus 2, a C melody, a D melody, and an outro. Specifically, sections A1 and B1 of FIG. 5A are associated with configuration information for the intro. Also, Sections A2 and B2 are for the A melody structure information, Sections A3 and B3 are for the B melody structure information, Sections A4 and B4 are for the chorus structure information, Sections A5 and B5 are for the interlude structure information, and Section A6. and B6 are associated with outro configuration information. Furthermore, one section may be associated with multiple pieces of configuration information. For example, sections A1 and B1 may be further associated with configuration information indicating "start" (the starting section of the song). Also, sections A6 and B6 may be further associated with configuration information indicating an "end" (end section of a piece of music).

The priority section is a section that the user is likely to want to play, for example, a section corresponding to the climax of the song such as the chorus, intro, and outro, a section including singing, and a section with a high degree of difficulty. This section corresponds to the climax of the game. Additionally, the priority section may be a user-selected section. The musical score information indicates whether or not the section corresponds to the priority section. For example, the musical score information of sections A1, A4, A6, B1, B4 and B6 in FIG. 5A all indicate that they are priority sections. Also, the configuration information indicates that the sections corresponding to the chorus, intro, outro, etc. are priority sections.

The key information is referred to when raising or lowering the pitch in order to align the keys of the sections. For example, the key information indicates the height or depth of the key relative to the reference key, +1#, +2#, +3#, +4#, +5#, +6#, -1♭, +2♭, +3♭, +4 ♭, +5 ♭, and +6 ♭ are shown. Also, the chord information may indicate chords that are easy to connect in addition to indicating chord progressions. The attribute information includes information on rules for creating synthetic music. For example, the attribute information can be played simultaneously, can be played continuously (looped), cannot be used as an intro, cannot be used as an outro, can be cut in low tones, can be cut in high tones, and can be played later. Various attributes such as the ability to connect sections, the ability to connect a sound effect section before, the ability to overlap the sound effect section on the last part, the ability to overlap the sound effect section on the first part, etc. are shown. Note that the sound effect section is a section different from the music section, and is a section in which the sound effect is reproduced according to a predetermined operation of the user.

Furthermore, the attribute information included in the compatibility information includes information indicating compatibility indicating ease of connection with at least one other section. This degree of compatibility indicates, for example, the degree of ease of connection with sections of the same music. Specifically, in the example of FIG. 5B, after section A1, section A2 indicates the highest degree of compatibility with 100 points, and then section A3 indicates the degree of compatibility with 50 points. Also, before section B4, section B3 indicates the highest degree of compatibility of 100 points, section B2 indicates the degree of compatibility of 75 points, and next section B5 indicates the degree of compatibility of 50 points. These degrees of compatibility indicate that the higher the point, the easier the connection. Furthermore, the degree of compatibility also indicates the degree of ease of connection with sections of other songs. Specifically, in the example of FIG. 5B, after section A2, section B3 exhibits the highest compatibility of 100 points, then section B2 exhibits compatibility of 75 points, followed by section B5 of 50 points. It shows the compatibility of the points.

That is, the attribute information indicates at least one of ease of connection with sections of the same or different music, ease of connection with previous sections, or ease of connection with sections connected behind. Also, the attribute information may be information indicating easily connected sections. In the example of FIG. 5B, the attribute information of section A1 may indicate that section A2 is the section most likely to be connected, and section A3 is the section most likely to be connected. Furthermore, the degree of compatibility may be obtained by calculation, for example, if the keys match, 50 points are added, and if the chord progressions are similar, 50 points are added, and the degree of compatibility is calculated as 100 points. can be done.

[Select preferred section]
When the user selects the synthetic music mode, the music creation unit 80 creates a synthetic music from the selected multiple songs, for example, two base songs A and sub-song B. However, the user may select three or more pieces of music, and in this case also, a synthetic piece of music can be created. A case where the user selects two songs will be described below.

As shown in FIG. 4, the music creation unit 80 includes a section determination unit 83 as section determination means for determining a section of the base music that forms the basis of the synthesized music and a section of the sub-music that is synthesized with the base music. ing. The section discrimination unit 83 discriminates, for example, the section included in the music first selected by the user as the section of the base music. Alternatively, the section determination unit 83 may determine a section included in a song selected by the user or randomly selected as a section of the base song.

Also, the section discrimination unit 83 discriminates, for example, a section included in the second and subsequent songs selected by the user as a sub-song section to be synthesized with the base song. Alternatively, the section determination unit 83 may determine a section included in a song randomly selected from songs other than the base song as a section of the sub-song. Then, the reproduction section selection unit 81 refers to the configuration information as reference information, and determines the section to be reproduced first or last in the synthesized music from among the sections of the base music.

In the example of FIG. 5A, the reproduction section selection unit 81 determines the section A1, which is the priority section of the base music A, as the section to be reproduced first from the music data. The configuration information of this section A1 indicates that section A1 is an intro. That is, the reproduction section selection unit 81 selects the section A1 of the base song A that is used as the intro. Alternatively, the playback section selection unit 81 may randomly select a priority section from all songs selected by the user or from songs not selected by the user. Also, the reproduction section selection unit 81 may select the section selected by the user as the priority section.

Furthermore, the reproduction section selection unit 81 may determine the section to be reproduced last from among the priority sections of the base music. That is, the playback section selection unit 81 may select both the first and last sections of the synthesized music from among the priority sections of the base music. In the example of FIG. 5A, the playback section selection unit 81 can select section A6, which is the priority section of the base song A, as the last section to be played back from the song data. This section A6 configuration information indicates that section A6 is an outro. That is, the playback section selection unit 81 can select section A6 of the base song A to be used as the outro.

Then, the reproduction section selection unit 81 refers to the configuration information as reference information, and randomly selects the section B4, which is the priority section, from among the sub-music pieces B different from the base music piece A. FIG. Similarly, the playback section selection unit 81 repeats selection of priority sections. Alternatively, the reproduction section selection unit 81 may refer to the configuration information and select a priority section positioned after the selected priority section (for example, the intro) as the composition of the music. In the example of FIG. 5A, the playback section selection unit 81 can extract sections B4 and B6 positioned after the intro from the sub-music B as the structure of the music. Then, the reproduction section selection unit 81 can select the section B4 (chorus) close to the intro from among the extracted sections B4 and B6 as a priority section.

Furthermore, the reproduction section selection unit 81 may select priority sections from among the same music. In the example of FIG. 5A, the reproduction section selection unit 81 may select the outro section B6 as a priority section positioned after the chorus section B4. Further, the reproduction section selection unit 81 may select a priority section located before the selected priority section, or may repeatedly select the already selected section as the composition of the music. For example, in the example of FIG. 5A, the reproduction section selection unit 81 may select the intro section B1 or the chorus section B4 as the priority section positioned after the chorus section B4.

Select connection section
Next, based on the reference information, that is, referring to the degree of compatibility as the degree of compatibility information, the connection section selection unit 82 selects a connection section having good compatibility with the priority section from the music data. Specifically, based on the degree of compatibility, the connection section selection unit 82 selects the preceding section preceding section B4 already selected as the priority section and the succeeding section following section A4 already selected as the priority section. At least one is selected from music data. That is, the connection section selection unit 82 selects, as at least part of the connection section, one or two of the connection sections consisting of two sections, or one or two of the connection sections consisting of three or more sections. choose one. It should be noted that the connection section is arranged in the synthesized music so that at least part of it is located between the priority sections.

First, the connection section selection unit 82 extracts a section that is compatible with the priority section that has already been selected as a candidate section for the succeeding section or the preceding section. In the example of FIG. 5B, the connection section selection unit 82 extracts sections A2 and A3 that are compatible with the already selected section A1 as candidate sections for subsequent sections. The connection section selection unit 82 also extracts sections B2, B3, and B5 that are compatible with the already selected section B4 as candidate sections for preceding sections. By selecting sections that constitute connection sections from among these candidate sections, the connection section selection unit 82 can select connection sections that are compatible with the priority section.

Next, the connection section selection unit 82 selects at least one of a section preceding the candidate section to be selected as the connection section and a section following the candidate section based on the degree of compatibility as the degree of compatibility information. Choose from In the example of FIG. 5B, the connection section selector 82 extracts sections B2, B3 and B5 as candidate sections following section A2 or A3. Alternatively, the connection section selection unit 82 may extract section A2 or A3 as the section preceding section B2, B3 or B5. That is, the connection section selection unit 82 further extracts, as a candidate section, a section that is compatible with section A2 or A3, which is a candidate section for the connection section, or section B2, B3, or B5, which is also a candidate section.

Subsequently, the connection section selection unit 82 extracts combinations whose ease of connection points are equal to or greater than a predetermined threshold from the combination patterns of the priority sections and the connection sections. Then, the connection section selection unit 82 randomly selects one combination from the extracted combination patterns. This allows the connection section selection unit 82 to select a connection section that precedes or follows the section to be selected as the connection section. In the example of FIG. 5B, the combination of sections A1, A2, B3 and B4 is 100 points of affinity between sections A1 and A2, 100 points of affinity between sections A2 and B3, and 100 points of affinity between sections B3 and B4. The degree of compatibility is 300 points by adding 100 points. Then, when the threshold is set to 250 points, in addition to this combination, the combination of sections A1, A2, B2 and B4 (250 points) and the combination of sections A1, A3, B3 and B4 (250 points) extracted. From among these, the connection section selection unit 82 randomly selects, for example, a combination of sections A1, A2, B3 and B4 shown in FIG. 5C.

Alternatively, the connection section selection unit 82 may select a combination showing the highest points from among the extracted combination patterns. In the example of FIG. 5B, the combination of sections A1, A2, B3 and B4 shows the highest point. Therefore, the connection section selection unit 82 may select sections A2 and B3 included in the combination as connection sections.

Furthermore, the connection section selection unit 82 may refer to attribute information when creating a synthesized music piece. For example, the connection section selection unit 82 may exclude sections associated with attribute information indicating that they cannot be used as intros when selecting the first priority section of the synthesized music. Furthermore, the connection section selection unit 82 may refer to at least one of the key information and the code information as compatibility information. For example, the connection section selection unit 82 can select a section that has all the keys for the priority section as a connection section that is compatible with the priority section. Also, the connection section selection unit 82 can select a section whose chord progression is similar to that of the priority section as a connection section that is compatible with the priority section.

Furthermore, the connection section selection unit 82 may refer to at least one of the key information and the code information to add or subtract a predetermined point to or from the degree of compatibility. For example, the connection section selection unit 82 may add predetermined points to at least one of a section with matching keys and a section with similar chord progressions. Alternatively, the connection section selection unit 82 may subtract a predetermined point from at least one of the section where the keys are not aligned and the section where the chord progression is not similar.

Also, the connection section selection unit 82 may select, as the connection section, a section other than the sections forming the music selected by the user. For example, the connection section selection unit 82 repeats a section of music not selected by the user, a sound effect section that reproduces sound effects in response to the user's operation, a section that consists of sound effects such as beat sounds, and a part of the music. A loop section, a generic section pre-created for a connection section, a specific section pre-created for a connection section of a particular song, etc. may be selected as a connection section.

The game program 42 of such a game machine 10 controls the control unit 30 as a computer based on reference information associated with each of the plurality of sections and referred to for selecting the priority section to be included in the synthesized music. , function as reproduction section selection means for selecting a priority section from music data. Furthermore, the game program 42 causes the control unit 30 to function as connection section selection means for selecting connection sections to be positioned between priority sections from the music data based on the reference information.

Note that when connecting two sections, the music composition section 80 may change at least one of the last part of the preceding section and the beginning part of the succeeding section. For example, the music creating section 80 may perform at least one of fade-out, which gradually lowers the volume of the preceding section, and fade-in, which gradually increases the volume of the subsequent section. Furthermore, the music creating unit 80 may cut the low range of at least one of the preceding section and the following section to emphasize the high range, or may cut the high range to emphasize the low range. Furthermore, the music creation unit 80 may insert a sound effect or a musical piece for presentation into at least one of the last part of the preceding section and the beginning part of the following section. Also, the music creating section 80 may change the section so that only part of the section, for example, part of the section of the sub-music, is reproduced.

[Create score data]
As shown in FIG. 4, the music creating unit 80 of the control unit 30 has a musical score data creating unit 84 that creates musical score data of a synthesized musical piece. For example, the musical score data creation unit 84 reads musical score data corresponding to sections forming the synthetic musical piece from the memory 40 and arranges them according to the order of the sections to create musical musical score data of the synthetic musical piece. In the example of FIG. 5C, musical score data corresponding to sections A1, A2, B3 and B4 are arranged in this order.

In addition to the musical score data corresponding to each section of the music, the memory 40 stores, for example, musical score data corresponding to the effect sound, general musical score data corresponding to all musical pieces, and specific musical score data created corresponding to a specific musical piece. and other musical score data. The musical score data creating section 84 may use at least one of these musical score data instead of the musical score data corresponding to the section. Note that the musical score data is created for each section, but there may be multiple sets of musical score data corresponding to the difficulty level for one section.

[Select sound effects section]
As shown in FIG. 4, the music composition section 80 of the control section 30 has a sound effect section determination section 85 as sound effect section determination means. Further, the reproduction control section 60 of the control section 30 has a dramatic sound reproducing section 61 as a dramatic sound reproducing means. Hereinafter, with reference to FIGS. 6A to 6D, a case where the sound effect section determination unit 85 inserts a sound effect section as a section connecting two sections of the synthesized music will be described.

The effect sound is a sound that is reproduced when the user performs a predetermined effect operation according to the operation procedure corresponding to the score data corresponding to the effect sound section (hereinafter referred to as "effect score data"). The sound effect section is associated with reference information that is referenced to identify this sound effect. Further, the effect sound reproduction unit 61 reproduces the effect sound corresponding to the effect operation when the user performs a predetermined effect operation. Note that there are a sound effect section in which only sound effects are reproduced, and a sound effect section in which sound effects such as music or bass sound are reproduced in addition to sound effects. Furthermore, in the case of a sound effect section in which music or sound effects are reproduced, the sound effect reproduction unit 61 reproduces the music or sound effects in addition to the sound effects corresponding to the user's operation. Further, the performance musical score data is, for example, one measure (four beats) long, and is configured to guide one or more objects. Note that the performance musical score data may be created in advance, or may be automatically created by the music creating section 80 .

In the example of FIG. 6A, the sound effect section determination unit 85 inserts the sound effect section between the section B4 as the priority section and the section A2 as the connection section. Further, the sound effect section determination unit 85 may determine sound effect sections so that the sound effects are played simultaneously with at least part of the music section. Even when inserting a dramatic sound section in this way, the musical tone changes depending on the dramatic sound, so the dramatic sound section is used to connect two sections. In the example of FIG. 6B, the sound effect section determination unit 85 determines the sound effect section so that the sound effect is reproduced simultaneously with the last part of the section A2 as the connection section. Further, in the example of FIG. 6C, the sound effect section determination unit 85 determines sound effect sections so that the sound effects are reproduced simultaneously with the first part of section B4 as the priority section. Furthermore, in the example of FIG. 6D, the sound effect section determination unit 85 determines the sound effect sections so that the sound effects are reproduced over the section B3.

Specifically, the guiding unit 71 guides the user to the operation procedure of the effect operation according to the effect score data corresponding to the effect sound section. For example, the guidance unit 71 guides the user to the operation procedure of the effect operation by means of the effect object 24 or the line object 25 shown in FIG. The user operates the effect button 17 or the rotary device 18 of the operation unit 14 according to the operation procedure of the guided performance operation. Then, the effect sound reproducing unit 61 reproduces the effect sound from the speaker 13 according to the user's effect operation. At this time, if the user operates correctly, the sound effect reproducing unit 61 reproduces the sound effect as set in the sound effect section. On the other hand, if the user makes an erroneous operation, the effect sound reproduction unit 61 either does not reproduce the effect sound or reproduces an erroneous effect sound according to the user's operation.

Here, the performance operation by the user may or may not be added to the score. If it is added, the user will be motivated to reproduce the effect sound, and the user will be able to maintain a sense of tension until proceeding to the next section. If the addition is not made, the user is given the option of not performing the performance operation, and the user can arrange the music to be reproduced.

The sound effect section determination unit 85 determines a sound effect section for connecting at least two sections, for example, priority sections, a priority section and a connection section, or connection sections. For example, a dramatic sound section is automatically determined as a connection between sections of the synthesized music. As an example, the sound effect section determination unit 85 randomly determines whether or not to insert the sound effect section when the connection section selection unit 82 selects the connection section or after selecting the connection section. Then, when it is determined to insert a sound effect section, the sound effect section determination unit 85 inserts the sound effect section between arbitrary sections. Also, the effect sound section may be inserted at the beginning of the section or at the end of the section instead of between the sections.

A plurality of effect sound sections are created, and the effect sound section determination unit 85 selects the effect sound section, for example, at random or based on tune information indicating the key, volume, tempo, etc. representing the music to be inserted. . Further, the sound effect section determination unit 85 may extract and select a sound effect section that is compatible with the sections before and after inserting the sound effect section from the music data. Alternatively, the sound effect section determination unit 85 may select an automatically generated sound effect section. For example, the automatically generated performance score data of the performance sound section may be data in which objects are guided at random, or data in which objects are guided in a pattern based on the tone information of the base music or sub music. good too. Note that the tune information is determined in advance for each piece of music and stored in the memory 40 or the like.

Also, if there is a sound effect section corresponding to all songs and a sound effect section corresponding to a specific song, the sound effect section determining unit 85 selects the effect sound so that it is inserted only into the corresponding song. Select a section. Further, the sound effect section determining unit 85 may insert a plurality of sound effect sections continuously, or may insert the same sound effect sections continuously. However, the sound effect section determination unit 85 inserts the sound effect sections associated with the reference information indicating the rule of inserting them so as not to continue.

Alternatively, the sound effect section determination unit 85 inserts a sound effect section between sections instead of the connection section when the connection section selection unit 82 cannot extract a candidate section that is compatible with the priority section. do. Further, the sound effect section determining unit 85 may refer to attribute information as reference information to determine the sound effect section. For example, if the attribute information indicates that a sound effect section can be connected at the end of the section, the sound effect section determination unit 85 inserts the sound effect section so as to follow the end of the section. If the attribute information indicates that the sound effect section can be connected to the beginning of the section, the sound effect section determining unit 85 inserts the sound effect section so as to precede the beginning of the section.

When inserting a sound effect section, the musical score data determination unit reads out the musical score data corresponding to the sound effect section from the memory 40, and synthesizes the other musical score data and the musical score data by arranging the musical score data according to the order of the sections. Create music notation data. In the example of FIG. 6A, the musical score data determining unit arranges the performance musical score data between section A2 and section B4. Therefore, the guidance means guides the operation procedure of the effect operation between the two sections. When the user correctly operates the game according to the effect operation, the effect sound reproduction unit 61 reproduces the effect sound set in the effect sound section.

Also, the musical score data determination unit may arrange musical score data for presentation together with musical score data corresponding to the section of the music piece. That is, the musical score data determination unit may arrange the musical score data so as to overlap the sections of the musical composition. In the example of FIG. 6B, the musical score data determination unit arranges the performance musical score data so as to overlap the last part of the musical score data corresponding to section A2. Also, in the example of FIG. 6C, the musical score data determination unit arranges the performance musical score data so as to overlap the first portion of the musical score data corresponding to section B4. Furthermore, in the example of FIG. 6D, the musical score data determination unit arranges the performance musical score data so as to overlap the entire musical score data corresponding to section B3. When the performance musical score data is arranged in this way, the guidance means will display the performance in the last part of the section to be played first of the two sections or the first part of the section to be played later of the two sections. It guides the operating procedure of the operation.

Note that the connection section selection unit 82 can also select the effect sound section as the connection section based on the degree of compatibility information as reference information. In this case, the connection section selection unit 82 functions as the effect sound section determination unit 85 .

The game program 42 of the game machine 10 as described above causes the control unit 30 as a computer to function as playback section selection means for selecting at least two sections to be included in the synthesized music from the music data. The game program 42 also causes the control unit 30 to function as sound effect section determination means for determining a sound effect section for connecting at least two sections. Further, the game program 42 causes the control unit 30 to function as effect sound reproduction means for reproducing effect sounds corresponding to the effect operation when the user of the game performs a predetermined effect operation. Further, the game program 42 guides the control unit 30 to the operation procedure of the game, and guides the operation procedure of the effect operation according to the musical score data corresponding to the effect sound section. function as

With such a game machine 10, it is possible to insert an effect sound section between connected sections when generating a synthesized music. As a result, even if the keys, volumes, or tempos of the sections to be connected are different, it is possible to maintain the unity of the synthesized music and eliminate the user's sense of incongruity. That is, if the sections to be connected differ, for example, in key, volume or tempo, a sudden change in at least part of them would confuse the user. Therefore, by inserting the effect sound section, it is possible to eliminate the sense of incongruity when connecting the sections. Also, even if the keys, volumes, or tempos of the sections to be connected are similar, it is possible to create unity as a synthesized music piece.

In addition, it is possible to connect the sections of the music by the effect sound reproduced by the user performing the effect operation. Therefore, it is possible to give the user the experience of arranging the synthesized music by himself/herself. Furthermore, the user feels that the sections to be connected are smoothly connected to each other by playing the effect sound that is compatible with the sections to be connected. Therefore, the two sections can be connected in such a way that the integrity of the composition is maintained. As a result, it is possible to create a synthesized musical composition that does not give the user a sense of discomfort.

[Simultaneous playback of sections]
As shown in FIG. 4, the reproduction control section 60 of the control section 30 has a simultaneous reproduction section 62 as simultaneous reproduction means for reproducing at least part of two sections, for example, two connection sections. Specifically, when at least two connection sections among the connection sections satisfy a predetermined condition, the simultaneous reproduction unit 62 reproduces at least part of these sections simultaneously. This predetermined condition is, for example, that the degree of compatibility between the two sections exceeds a predetermined threshold. Alternatively, it corresponds to at least one of matching the key of both sections, similar chord progression of both sections, matching tempo of both sections, matching length of both sections, etc. may be set as a predetermined condition. Simultaneous reproduction will be described below with reference to FIGS. 7A to 7C.

The simultaneous reproduction unit 62 randomly reproduces two connection sections at the same time when it determines that a predetermined condition is satisfied. For example, when section A2 and section B3 are selected as connection sections, the simultaneous reproduction section 62 determines whether or not section A2 and section B3 can be reproduced simultaneously. When it is determined that simultaneous reproduction is possible, the simultaneous reproduction section 62 randomly determines whether or not to perform simultaneous reproduction. Alternatively, the simultaneous playback unit 62 may refer to the attribute information and determine to perform simultaneous playback when it indicates that simultaneous playback is possible. Then, when it is determined to reproduce simultaneously, as shown in FIG. 7A, the simultaneous reproduction unit 62 arranges the sections so that section A2 and section B3 are reproduced simultaneously. It should be noted that the determination of whether or not to perform simultaneous playback may be made after the connection section selection unit 82 has extracted a section preceding or following the candidate section to be selected as the connection section.

Furthermore, the simultaneous reproduction section 62 may reproduce a part of the two sections simultaneously. In the example of FIG. 7B, part of section A2 and part of section B3 are played back simultaneously. Also, the simultaneous reproduction unit 62 may repeatedly reproduce two sections at the same time. In the example of FIG. 7C, section A2 and section B3 are repeatedly reproduced simultaneously. As a result, it is possible to prevent the length of the synthesized music from changing even if it is played back simultaneously. Note that the simultaneous reproduction unit 62 may simultaneously reproduce at least a part of three or more sections.

Alternatively, the simultaneous reproduction unit 62 may simultaneously reproduce priority sections or priority sections and connection sections. In addition to the sections obtained by dividing the music data of a song, the song data includes a sound effect section composed of sound effects according to user operations, a section composed of sound effects, and a section created corresponding to a specific song. In addition, other sections may be included, such as a section that repeatedly loops sounds of a predetermined length, a section that is created corresponding to an unspecified piece of music and repeatedly loops sounds of a predetermined length, and the like. In this case, the simultaneous reproduction section 62 may simultaneously reproduce the priority section or connection section and other sections.

In the case of simultaneous playback, the musical score data creation unit 84 assigns musical score data corresponding to one of the two connection sections to the simultaneous playback portion, that is, the two connection sections to be played back simultaneously. In the example of FIG. 7A, the musical score data creation unit 84 assigns musical score data corresponding to section A2 of sections A2 and B3 to be played back simultaneously. In addition, the musical score data creation unit 84 may allocate musical score data corresponding to the section whose playback is started first until the simultaneous playback ends, that is, until the section is switched between the two connected sections that are played back at the same time. In the example of FIG. 7B, the musical score data creation unit 84 assigns the musical score data of section A2, which was started to be played earlier, during the simultaneous playback. Then, when section A2 is switched to section B3, of the musical score data corresponding to section B3, the musical score data corresponding to the rest of the musical score data excluding the simultaneous playback portion is assigned.

Furthermore, in the case of simultaneous reproduction, the music creation section 80 may cut the low range of at least one of the sections to be reproduced simultaneously to emphasize the high range, or may cut the high range to emphasize the low range. For example, the music creation unit 80 cuts the high range of the section of the sub-music to emphasize the low range. Thereby, the base music can be emphasized more than the sub-music among the sections to be reproduced simultaneously. Also, at least one of the sections to be played back simultaneously may be changed based on sound quality, sound source, or musical instrument type. For example, one section may be changed to consist only of singing or only bass sounds. It should be noted that it is also possible to make changes to all of the sections that are played back simultaneously. Also, when simultaneously reproducing the last part of the preceding section and the first part of the succeeding section, the music creating unit 80 may change at least one of the last part and the first part. For example, the music creating section 80 may perform at least one of fade-out, which gradually lowers the volume of the preceding section, and fade-in, which gradually increases the volume of the subsequent section. Furthermore, the music creation unit 80 may insert a sound effect or a musical piece for presentation into at least one of the last part of the preceding section and the beginning part of the following section. Also, the music creating unit 80 may change one of the sections to be played back at the same time, for example, the section of the sub-music so that only a part thereof is played back.

When assigning the musical score data corresponding to one of the two connection sections, the musical score data creating unit 84 may assign the musical score data corresponding to either section of the base song or the sub-song. In the example of FIG. 7A, the musical score data creation unit 84 assigns musical score data corresponding to section A2 of the base song A. In the example of FIG. On the other hand, in the example of FIG. 7C , the musical score data creating unit 84 allocates musical score data corresponding to section B3 of sub-music B. As shown in FIG.

As a result of the musical score data being assigned in this way, when the simultaneous playback unit 62 performs simultaneous playback, the guiding means instructs the user to operate the operation procedure according to the musical score data corresponding to one of the two connection sections in the simultaneous playback portion. invite. Alternatively, the guidance means may randomly select one of the musical score data corresponding to the two connection sections in the simultaneous playback portion, and guide the user to the operation procedure according to the selected musical score data. In this case, the musical score data creating unit 84 sets two musical score data in association with the sections to be played back simultaneously.

Also, the connection section selection unit 82 may select an additional connection section from the candidate sections extracted as sections preceding or following the candidate section to be selected as the connection section. In the example of FIG. 7D, the connection section selection unit 82 selects section B2 from among the candidate sections and connects it after the simultaneously reproduced portion.

Simultaneous playback gives the user a feeling that the connected sections flow smoothly together. Therefore, the two sections can be connected in such a way that the integrity of the composition is maintained. As a result, it is possible to create a synthesized musical composition that does not give the user a sense of discomfort.

[Synthetic music creation flow]
A synthetic music composition flow will be described with reference to the flow chart of FIG. First, the control unit 30 determines whether or not the user has selected the synthetic music mode. Then, if the synthetic music mode is not selected, no synthetic music is created. On the other hand, if the synthetic music mode is selected, the music creating section 80 distinguishes between the base music section and the sub-music section (S601). Then, the reproduction section selection unit 81 determines a priority section to be reproduced first of the synthesized music (S602). Further, the reproduction section selection unit 81 selects the next priority section from songs different from the selected priority section (S603).

Next, the reproduction section selection unit 81 repeats selection of priority sections until a predetermined condition is satisfied (S604). As an example, the predetermined condition is that six sections are selected as priority sections or that the total time reaches a predetermined length. If the predetermined condition is satisfied (YES in S604), the connection section selection unit 82 selects, based on the degree of compatibility information, the subsequent section following the priority section played first among the priority sections, and the section between the priority sections. A preceding section preceding the priority section to be reproduced later is selected from the music data as at least a part of the connection section. For this purpose, the connection section selection unit 82 extracts sections that are compatible with the priority section that has already been selected as candidate sections for subsequent or preceding sections (S605).

Then, the connection section selection unit 82 selects a section that follows the preceding section and precedes the subsequent section from the music data as at least a part of the connection section. For this purpose, the connection section selection unit 82 extracts sections preceding or following the candidate section to be selected as the connection section (S606). It should be noted that sections preceding or following a candidate section may be further extracted for sections preceding or following the candidate section. Repeated extraction increases the number of sections included in the finally selected connecting section.

Subsequently, the connection section selection unit 82 extracts a combination whose degree of compatibility is equal to or greater than a predetermined threshold from the combination patterns of the priority section and the connection section. Then, the connection section selection unit 82 randomly selects one combination from the extracted combination patterns (S607). The connection section selection unit 82 selects sections included in this selected combination as connection sections. In this manner, the connection section selection unit 82 selects connection sections that are compatible with the priority section from the music data.

After that, the sound effect section determination unit 85 randomly determines whether or not to insert a sound effect section between the sections (S608). Then, if it is determined to insert a sound effect section (YES in S608), the sound effect section determination unit 85 inserts the sound effect section between arbitrary sections (S609). Note that the effect sound section may be inserted after the connection section selection unit 82 has extracted a section preceding or following the candidate section to be selected as the connection section. In this case, the connection section selection unit 82 selects one combination from the combination patterns of the sections into which the effect sound section is inserted. The connection section selection unit 82 then selects sections included in the selected combination as connection sections.

Subsequently, the simultaneous reproduction section 62 determines whether or not two consecutive sections can be reproduced simultaneously. If it is determined that simultaneous reproduction is possible, the simultaneous reproduction unit 62 randomly determines whether or not to simultaneously reproduce the two sections (S610). If simultaneous playback is determined (YES in S610), the simultaneous playback section 62 arranges the sections so that at least a part of the two sections is played back simultaneously (S611). It should be noted that the determination of whether or not to perform simultaneous playback may be made after the connection section selection unit 82 has extracted a section preceding or following the candidate section to be selected as the connection section.

Then, the musical score data creating unit 84 reads out the musical score data corresponding to the sections forming the synthesized music from the memory 40 . Also, if there is a sound effect section, the music score data creating unit 84 reads out the sound effect music data corresponding to the sound effect section from the memory 40 . Then, the musical score data creation unit 84 creates musical score data of the synthesized music (S612). This completes the creation of the synthesized music. Note that the music score data may be created simultaneously with the selection of each section. For example, when a priority section is selected, the musical score data creation unit 84 may automatically extract and arrange musical score data corresponding to the priority section.

By creating a composite music piece as described above, the reproduction section selection unit 81 can select a connection section that is connected to a priority section so as to maintain unity as a composite music piece. Furthermore, the connecting sections can be connected to the priority sections in an order that maintains their integrity as a composite musical piece. As a result, it is possible to create a synthetic musical piece that does not make the user feel uncomfortable, taking into account the overall structure of the synthetic musical piece.

[Highlighting]
When sections of different songs are played back simultaneously, the user can aurally determine which song is being played back, which may make it difficult to distinguish the song. Therefore, in order to indicate which song is being played, as shown in FIG. It has a discrimination section 52 and a highlighting section 53 as highlighting means.

The song identification unit 51 functions to present to the user of the game a specific display that identifies each of a plurality of songs, eg, two songs, that include sections that are being played at the same time. For example, the music identification unit 51 causes the monitor 12 to display each specific display (for example, an icon). Also, the dominant section discriminating unit 52 discriminates at least one superior section, which is superior to other sections, among the sections being reproduced at the same time. For example, the superior section determination unit 52 determines the section in which the user is guided to the operation procedure corresponding to the corresponding musical score data (the section in which the guidance unit 71 guides the operation procedure), the section in which the playback volume is louder than the other sections , and the section whose reproduction is started later than other sections, the section corresponding to at least one is determined to be the dominant section. A case will be described below where the section with the loudest playback volume is the superior section.

Based on the determination result of the superior section determining unit 52, the highlighting unit 53 relatively emphasizes the specific display of the superior section more than the specific displays of the other sections. This highlighting will be described with reference to FIGS. 9 and 10. FIG. In FIG. 9 , a base music icon 29A specifying the base music A and a sub music icon 29B identifying the sub music B are displayed above the plurality of lanes 22 . The superior section determination unit 52 determines which music section is superior when multiple music sections are reproduced simultaneously. In FIG. 9, the base song A and the sub song B are played at the same volume. Therefore, the superior section determination unit 52 determines that there is no superior section. Since there is no superior section, the highlighting unit 53 does not highlight the icon 29 . As a result, the base music icon 29A and the sub music icon 29B are displayed side by side with the same image size.

Next, as the game progresses, the reproduction control unit 60 lowers the volume of one song to make it lower than the volume of the other song. In this case, the superior section determination unit 52 determines that the section of the music with the loud reproduction volume is the superior section. In the example of FIG. 10, the reproduction volume of the sub-music B is higher than that of the base music A. In FIG. Therefore, the highlighting section 53 displays the sub music icon 29B larger than the base music icon 29A. Alternatively, the highlighting unit 53 may display the base music icon 29A smaller than the sub music icon 29B. Thus, it is possible to indicate to the user that the section of sub-music B is being played.

Further, the highlighting unit 53 may determine the size ratio of the icons according to the volume ratio of the reproduction volume of the songs. For example, if the playback volume of the sub-music B is 1.5 times that of the base music A, the highlighting unit 53 may display the sub-music icon 29B in a size that is 1.5 times that of the base music icon 29A. . Alternatively, the highlighting unit 53 may increase the difference in icon size as the difference in playback volume between songs increases.

Furthermore, when the specific display is an image, the highlight display unit 53 displays at least one of the color, hue, brightness, contrast, density, and display pattern of the image in addition to the size of the image. You can change it. If the specific display is anything other than an image, the highlighting by the highlighting display unit 53 may be, for example, changing the color ratio of the background, changing the color of the background color, hue, brightness, contrast, and density, or blinking the background color. may Moreover, in order to relatively emphasize and display the icon of the superior section, the highlighting unit 53 may display the icon of the section that is not the superior section in a weak tone. For example, the highlighting section 53 may display the other image in a low tone by making the other image smaller, making the other image lighter, blinking the other image, or the like. Further, the highlighting unit 53 may perform highlighting in a mode such as gradually enlarging the image, gradually darkening the image, and gradually changing the flickering cycle of the image, in order to gradually highlight the display. .

Also, when three or more music sections are to be reproduced simultaneously, the dominant section discriminating unit 52 discriminates at least one section as a superior section and highlights it. When the superior section determination unit 52 determines that a section whose reproduction is started after other sections is superior, the guide unit 71 performs an operation procedure according to the score data corresponding to the superior section. You can guide the user. For example, when allocating the musical score data corresponding to one of the two connection sections, the musical score data creating section 84 may assign the musical score data corresponding to the dominant section to the simultaneous reproduction portion. As a result, the guidance unit 71 guides the user to the operation procedure according to the musical score data corresponding to the superior section.

With such highlighting, it is possible to effectively convey the music being played back to the user and the audience watching around the user. Furthermore, by displaying the volume specific display according to the volume ratio of the playback volume, it is possible to inform the user and the audience of what song is being played and at what volume.

The game program 42 of the game machine 10 as described above causes the control unit 30 as a computer to function as simultaneous reproduction means for simultaneously reproducing at least a part of at least two sections of the two music sections. In addition, the game program 42 causes the control unit 30 to function as music identifying means for presenting the user of the game with a specific display identifying each of a plurality of music including sections that are being played back at the same time. Furthermore, the game program 42 causes the control unit 30 to function as superior section determination means for determining at least one superior section superior to the other sections among the sections being reproduced simultaneously. Further, the game program 42 controls the control unit 30 as highlighting means for displaying the specific display of the superior section in a relatively more emphasized manner than the specific displays of the other sections, based on the determination result of the superior section determination means. make it work.

Although the present invention has been described with reference to each embodiment, the present invention is not limited to the above embodiments. Inventions modified within the scope of the present invention and inventions equivalent to the present invention are also included in the present invention. Further, each embodiment and each modification can be appropriately combined within a range not contrary to the present invention.

For example, there may be one connection section. Furthermore, if a priority section is selected as the connection section, no other section may be included between the priority sections. In this case, instead of the connection section selection unit 82, the playback section selection unit 81 may select the priority section as the connection section.

The compatibility information may further include tempo information indicating the tempo of the section or length information indicating the temporal length of the section. In this case, the connection section selection unit 82 may select a section with the same tempo or a section with the same temporal length as the connection section that is easily connected to the priority section. Furthermore, the connection section selection unit 82 may refer to at least one of the tempo information and the length information to add or subtract compatibility points. Furthermore, the connection section selection unit 82 may select a connection section after aligning the keys of each section. As a result, it is possible to create a wider variety of synthesized music by increasing the number of options for easy-to-connect connection sections.

Alternatively, the playback section selection unit 81 may determine the composition of the synthesized music and then select the priority sections that constitute the synthesized music. As an example, the reproduction section selection unit 81 refers to the configuration information of the priority section of the base music, and determines the composition of the base music as the composition of the synthesized music. For example, if the priority section of the base song has configuration information indicating the configuration of the intro, chorus, and outro, the reproduction section selection unit 81 synthesizes the configuration including the intro, chorus, and outro in this order. Determined as the composition of the music.

Alternatively, if the base song includes intro, verse A, verse B, chorus 1, interlude, chorus 2, and outro in this order, the playback section selection unit 81 selects the intro, chorus 1, chorus 2, and outro. A priority section having configuration information indicating the configuration is selected from the base song or sub-song sections. Then, the connection section having the configuration information indicating the configuration of the A melody, B melody, and interlude is selected from the section of the base music or sub-music. After that, the playback section selection unit 81 arranges the priority sections and connection sections in order of introduction, A melody, B melody, chorus 1, interlude, chorus 2, and outro.

As a result, the overall structure of the synthesized music matches, so that the balance of the structure of the music can be maintained. Note that the playback section selection unit 81 may determine the structure of the synthesized music based on, for example, the structure of the music first or last selected by the user instead of the base music.

Further, when simultaneously reproducing the last part of the preceding section or the beginning part of the succeeding section with another section, the simultaneous reproducing section 62 may simultaneously reproduce only a time corresponding to a predetermined number of bars. For example, the simultaneous reproduction unit 62 may simultaneously reproduce only the time corresponding to 1 bar, 2 bars, 4 bars, or 8 bars.

For example, a plurality of sections obtained by dividing a plurality of music pieces into a plurality of sections may be created by automatically dividing the music piece by the game machine 10 . Also, a plurality of sections may be created by dividing a piece of music by the user. In these cases, each created section is stored in the memory 40 as part of the music data.

Also, the music creating section 80 may create a composite song from one base song and two or more sub-songs as sections of three or more songs. For example, when creating a composite song from a base song A, a sub song B, and a sub song C, in addition to the sections shown in FIG. A priority section and a connection section are also selected from among C2, C3, C4, C5 and C6.

Also, the connection section selection unit 82 may select a section that is a priority section as a connection section. In this case, the following priority section is arranged in succession to the preceding priority section. For example, section B4 of sub-song B can be placed after section A1 of base song A. Furthermore, the connection section selection unit 82 selects from the music data a connection section that should be located between the section B4, which is the priority section, and another priority section following the section B4.

Also, the connection section selection unit 82 may select a priority section as the connection section. In this case, the priority section selected by the reproduction section selection unit 81 and the priority section selected by the connection section selection unit 82 are continuous. For example, the playback section selection unit 81 may select section A1, which is the priority section, and the connection section selection unit 82 may select section A1 as the subsequent connection section. As a result, the section A1 is played continuously, so the length of the synthesized music can be adjusted.

In the case of simultaneous playback, the music creating section 80 may change at least one of the sections to be played back simultaneously from the start to the end of the entire section. For example, the music composer 80 can change entire sections based on range, tone quality, sound source, or instrument type. Specifically, the music creation unit 80 can change the entire section so that it is composed only of singing or only sound effects, so that the high or low range is emphasized, or the volume is increased or decreased. Note that when changing the entire section, even if only a part of each section is to be played back simultaneously, the entire section including the part to be played back at the same time is changed.

Various aspects derived from each embodiment and each modification described above will be described below. In addition, in order to facilitate understanding of each aspect, reference numerals shown in the accompanying drawings are added in parentheses. However, the reference numerals are not intended to limit the present invention to the illustrated forms.

The game system 10 selects at least two music sections from music data including a plurality of sections obtained by dividing a plurality of music into a plurality of sections, and creates a synthesized music. The game system 10 to be created includes playback section selection means 81 for selecting at least two sections to be included in the synthetic music from the music data, and an effect sound section for connecting the at least two sections. effect sound section determination means 85 to be determined; effect sound reproduction means 61 for reproducing effect sounds corresponding to the effect operations when a player of the game performs a predetermined effect operation; Guidance means 71 for guiding, which guides the operation procedure of the production operation in accordance with the musical score data corresponding to the production sound section.

With this game system, it is possible to eliminate the sense of incongruity when inserting the effect sound section and connecting the sections. Note that when creating a synthesized music, sections other than the dramatic sound section can be connected by a known method. For example, the section corresponding to the chorus may be selected from the music selected by the player, and the selected sections may be randomly connected.

The effect sound section determining means 85 determines the effect sound section based on reference information that is associated with each of the plurality of sections and includes compatibility information for determining compatibility with other sections. As a result, it is possible to maintain the unity of the synthesized music and eliminate the sense of incongruity of the player.

The guide means 71 guides the operation procedure of the effect operation between the at least two sections.

The guiding means 71 guides the operation procedure of the effect operation in the last part of the section to be reproduced first among the at least two sections or the first part of the section to be reproduced later among the at least two sections. to guide

According to these aspects, it is possible to connect the sections of the music by the effect sound reproduced by the player performing the effect operation. Therefore, it is possible to give the player the experience of arranging the synthesized music by himself/herself.

A connection section selection means 82 is further provided for selecting a connection section to be positioned between the at least two sections from the music data. As a result, it is possible to select connection sections that connect sections so as to maintain unity as a synthesized musical composition. Note that the connection section selection means 82 can select a section other than the effect sound section as the connection section.
