Further, unless otherwise specified, the scope of the present invention is not limited to the embodiments specifically described below.

  FIG. 1 shows a state in which a game machine 10 which is an example of a game system is viewed from the front. For example, the game machine 10 can play a predetermined game by consuming a predetermined value. However, the game system of the present 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). Also good. In addition, the type of game provided by the game machine 10 may be a game in which music is played during play, for example, various games such as a shooting game, a race game, a role playing game, and a fighting game. Hereinafter, a case where the game system is an arcade game machine and provides a music game will be described unless otherwise specified.

  The game machine 10 reproduces sounds such as music, production sound, and the like, a housing unit 11 in which the control unit 30 and the memory 40 (FIG. 3) are housed, a monitor 12 that is an example of a display unit that displays a game screen. And a speaker 13. An operation unit 14 is disposed 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 that are operated to reproduce effect sounds such as a bass sound and a drum sound, and two rotation devices that can be rotated. 18. The start button 15, the operation button 16, and the effect button 17 are operated by being pushed down by the user. The rotating device 18 is operated by the user rotating 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 when starting a game, selecting music, setting a game difficulty level, and the like. When starting the game, the user operates the start button 15 in accordance with an instruction on the start screen displayed on the monitor 12. For example, the user selects various settings such as music to be played, game mode, and difficulty level of the game. Further, the user can select a normal mode and a composite music mode from the game modes. When the normal mode is selected, the user plays each of the selected music piece or pieces. When the composite music mode is selected, the user selects a plurality of music pieces and plays the composite music created by the game machine 10 based on the selected plurality of music pieces. When the game is started, the user operates the operation button 16, the effect button 17, and the rotation device 18 in accordance with the operation procedure guidance by the object moving on the game screen.

  FIG. 2 is an example of a game screen displayed on the monitor 12. In the lower part of the game screen, there is an image simulating the operation unit 14 of the game machine 10, and there is an operation line 21 extending in the left-right direction of the game screen between the images simulating the two rotation devices 18. Further, six lanes 22 extend in the vertical direction of the game screen in the direction intersecting the operation line 21. On these lanes 22, a normal object 23 on one lane 22, an effect object 24 on two lanes, and a line object 25 crossing the plurality of lanes 22 are displayed. These objects are displayed to guide the user to the game operation procedure. 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. When the user's game operation timing and the object arrival timing coincide, the user's score is added. If the timings do not match, the user's score may be subtracted.

  The normal object 23 corresponds to the operation button 16 and is displayed on any of the four lanes 22. Then, the user presses down the corresponding operation button 16 in accordance with the timing when the normal object 23 reaches the operation line 21. The effect object 24 corresponds to the effect button 17 and is displayed across the two lanes 22, and the user performs the corresponding effect button 17 in accordance with the timing at which the effect object 24 reaches the operation line 21. Press down. When the timing when the user depresses the effect button 17 and the arrival timing of the effect object 24 coincide with each other, the effect sound is reproduced from the speaker 13.

  The line object 25 is displayed so as to cross each lane 22 in the range from the lane 22 at one end to the lane 22 at the other end of the lanes 22 at the left end and the right end of the game screen. The line object 25 is displayed by being distinguished by, for example, color so as to correspond to the right rotation device 18 and the left rotation device 18, respectively. Further, for example, a triangular operation mark (not shown) that moves in the left-right direction on the operation line 21 so as to correspond to each line object 25 is displayed. These operation signs are also displayed by being distinguished by colors, for example, so as to correspond to the left and right rotating devices 18, respectively. Then, for example, the user matches the line object 25 with the position in the left-right direction on the operation line 21 of the operation sign in accordance with the timing when the line object 25 in the rightmost lane 22 reaches the operation line 21. The right rotation device 18 is rotated. Depending on the position at which the line object 25 intersects the operation line 21, the right rotation device 18 is appropriately rotated leftward or rightward for operation. Such an operation is the same for the rotation device 18 on the left side, and a description thereof will be omitted. The position on the operation line 21 of the operation sign that moves within the screen by the user rotating the rotation device 18 and the intersection position of the operation line 21 of the line object 25 have a predetermined relationship (for example, within a predetermined range). ), A continuous effect sound is reproduced from the speaker 13.

  On the right side of the plurality of lanes 22 is a score display unit 26 that displays the score obtained by the user. There is a clear zone 27 at the top of the score display unit 26, and the gauge 28 that displays 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. In addition, an icon 29 is displayed above the plurality of lanes 22 as an example of a specific display for specifying the music being played. For example, this icon 29 is an image that reminds the user of music, and the user who has seen the icon 29 can specify the music being reproduced. In addition, the icon 29 can be used to identify a song being played to a viewer other than the user who has viewed the game screen, for example, a spectator who is watching around the user. The specific display may be various displays such as a jacket image of a music, characters such as a music title, a color, and a figure as long as the user is reminded of the music. Below, the case where the icon 29 is displayed as a specific display is demonstrated.

  When the game is started, a game screen is displayed on the monitor 12 and music is reproduced from the speaker 13. Then, the user plays the game by depressing the operation button 16 and the effect button 17 in accordance with the operation procedure displayed on the monitor 12, that is, the movement of the normal object 23 and the effect object 24. At this time, when the user depresses the effect button 17, the effect sound is reproduced from the speaker 13. Further, the user plays the game by turning the rotation device 18 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 unit 30 in the housing unit 11. The control unit 30 functions as a computer of the game system and includes, as an example, a CPU, SPU, and GPU (not shown). And the control part 30 controls the whole game machine 10 based on the program memorize | stored in the memory 40, and also comprehensively controls various processes. The memory 40 is a computer-readable recording medium that stores a control program 41 and a game program 42. As an example, the memory 40 includes 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. Note that the control unit 30 may perform control 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), a USB memory, or a server on the Internet.

  The control unit 30 includes a display control unit 50 that displays a game screen on the monitor 12 and a reproduction control unit 60 that reproduces music on the speaker 13. In addition, the control unit 30 includes an operation evaluation unit 70 that evaluates a user's game operation input from the operation unit 14 and calculates a score, and a music creation unit 80 that selects a section constituting a composite music, which will be described later. is doing. Each unit is generated as each logical device in the control unit 30 and is 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, illustration of some logical devices is omitted.

  The memory 40 includes, as game data 43 used in the game, for example, image data such as icons 29, objects, and backgrounds, music data such as music, sound effects and effect sounds, and musical score data defining the operation procedure of the game. Is remembered. The song data includes data corresponding to a plurality of songs each divided into a plurality of sections. Data corresponding to the plurality of music pieces is stored in a state of being divided into a plurality of sections. The musical score data is composed of data such as the type of object, the timing to be operated, and the arrival position on the game screen. The musical score data is stored in a state of being divided into a plurality of sections for each music piece, and the timing for operating the object is stored as, for example, the elapsed time from the beginning of the section. Note that the timing to be operated may be stored as the 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. When stored as the number of beats, adjustment is easy even when the tempo during playback is changed. The music data may include data of each of a plurality of music pieces, and the musical score data may include a plurality of sets of data corresponding to the difficulty level of the data of one music piece. The display control unit 50 displays an image on the monitor 12 at a predetermined timing based on the image data and the musical score data. Further, the reproduction control unit 60 causes the speaker 13 to reproduce sound based on the music data. Furthermore, 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. Note that at least a part of the game data 43 may be stored in an external storage device.

  As shown in FIG. 4, the operation evaluation unit 70 includes a guide unit 71 that functions as a guide unit that guides the game operation procedure to the game user. The operation evaluation unit 70 includes an evaluation unit 72 that evaluates a game operation based on a user's game operation input from the operation unit 14. Specifically, the guide 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 unit 71 moves each object so that the object reaches the operation line 21 at a predetermined operation timing. As described above, the guide unit 71 guides the user about the button or device of the operation unit 14 to be operated by the user and the operation timing thereof.

  The evaluation unit 72 determines which button or device in the operation unit 14 is operated based on the musical score data. The operation timing is set at the center of a predetermined length of operation time. And the evaluation part 72 detects the user's game operation with respect to the button or device which should 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 center timing of the operation time (the deviation amount is zero), the evaluation unit 72 highly evaluates the user operation and adds a high score.

  Further, when the evaluation unit 72 detects a game operation at a slightly early or slightly later timing from the center of the operation time (the amount of deviation is small), the evaluation unit 72 evaluates the user's operation normally and adds a normal score. Furthermore, if the evaluation unit 72 detects a game operation at a large early or large timing from the center of the operation time (a large amount of deviation) or does not detect a game operation within the operation time, the user has failed in the operation. The score is subtracted or not added.

  And the display control part 50 displays the image which shows the evaluation result by the evaluation part 72 on a game screen. For example, when adding a high score, the display control unit 50 displays “CRITICAL”. Moreover, the display control part 50 displays the character "NEAR", when adding a normal score. Further, the display control unit 50 displays “ERROR” when subtracting the score. In addition, the display control part 50 may display a score with a number with a character, and may display a total score on a game screen during a game.

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

[Create composite music]
The music creation unit 80 of the control unit 30 selects at least two music sections from music data including a plurality of sections obtained by dividing a plurality of music pieces into a plurality of sections so that these sections are included. Create a composite song. Hereinafter, the creation of the composite music will be described with reference to FIGS.

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

  As an example, the reference information is information indicating that it is a priority section to be included in the synthesized music, composition information indicating positioning in the music composition, and a musical score indicating that the user is likely to want to play Contains information. Furthermore, the reference information includes compatibility information for determining the compatibility of the connection with other sections. The 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. Note that the music creation unit 80 may refer to key information when creating a composite music so that the keys of successive sections are aligned. Furthermore, the music creation unit 80 may change the volume and tempo of successive sections when creating a composite music. These changes may be made in accordance with any section, that is, only one of them may be changed, or both sections may be changed. Alternatively, the music creation unit 80 may align at least one of keys, volume, and tempo between music when creating a composite music. When there is a song whose key or the like changes in the middle of the song, the change of the key or the like in the song is maintained by uniformly changing the entire song. When aligning the key, volume, and tempo, the key, volume, and tempo may be changed to match any of the music pieces, or may be aligned with a key, volume, and tempo that are not any of them.

  The configuration information indicates, for example, each configuration such as an intro, A melody, B melody, chorus 1, interlude, chorus 2, C melody, D melody, and outro. Specifically, sections A1 and B1 in FIG. 5A are associated with intro configuration information. In addition, sections A2 and B2 are information on A melody, sections A3 and B3 are information on B melody, sections A4 and B4 are information on rust, sections A5 and B5 are information on interlude, and section A6 And B6 are associated with the outro configuration information. Furthermore, one section may be associated with a plurality of pieces of configuration information. For example, the sections A1 and B1 may be further associated with configuration information indicating “start” (start section of music). Further, the sections A6 and B6 may be further associated with configuration information indicating “end” (music end section).

  A priority section is a section that the user is likely to want to play, such as a section corresponding to a mountainous area such as rust, intro, and outro, a section that includes singing, and a high difficulty section. This is the section corresponding to the mountain of the game. Further, the priority section may be a section selected by the user. The musical score information indicates whether it corresponds to the priority section. For example, the musical score information of sections A1, A4, A6, B1, B4, and B6 in FIG. 5A indicates that all correspond to priority sections. Further, the configuration information indicates that the priority section is a section corresponding to chorus, intro, outro, and the like.

  The key information is referred to when the pitch is raised or lowered to align the keys between sections. For example, the key information indicates the height or the height of the key with respect to the reference key, and + 1 #, + 2 #, + 3 #, + 4 #, + 5 #, + 6 #, −1 ♭, + 2 ♭, + 3 ♭, +4 ♭, + 5 ♭, and + 6 ♭ are shown. Further, the chord information may indicate a chord that is easily connected in addition to the chord progression. The attribute information includes information related to rules for creating a composite music piece. For example, the attribute information can be played back simultaneously, can be played continuously (loop playback), cannot be used as an intro, can not be used as an outro, can cut bass, can cut treble, Various attributes such as that the section can be connected, the stage sound section can be connected before, the stage sound section can be overlaid on the last part, and the stage sound section can be overlaid on the first part. The effect sound section is a section that is different from the music section, and is a section in which the effect sound is reproduced in accordance with a predetermined operation by the user.

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

  That is, the attribute information indicates at least one of the ease of connection with a section of the same or different music, the ease of connection with a section connected in front, or the ease of connection with a section connected behind. The attribute information may be information indicating sections that are easily connected. In the example of FIG. 5B, the attribute information of the section A1 may indicate that the section that is most easily connected is the section A2, and the section that is next easily connected is the section A3. Furthermore, the degree of compatibility may be obtained by calculation. For example, when the keys match, 50 points are added, and when the chord progression is similar, 50 points are added to calculate the degree of compatibility as 100 points. Can do.

[Select priority section]
When the user selects the composite music mode, the music creation unit 80 creates a composite music from a plurality of selected music pieces, for example, two base music pieces A and sub music pieces B. However, the user may select three or more music pieces, and in this case as well, a composite music piece can be created similarly. Below, the case where a user selects two music is demonstrated.

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

  In addition, the section determination unit 83 determines, for example, a section included in a music piece selected by the user after the second time as a section of a sub music synthesized with the base music. 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 sub-musical section. Then, the playback section selection unit 81 refers to the configuration information as reference information, and determines the section to be played back first or last in the composite music from the sections of the base music.

  In the example of FIG. 5A, the playback section selection unit 81 determines a section A1 that is a priority section of the base music A as a section to be played back first from the music data. The configuration information of the section A1 indicates that the section A1 is an intro. That is, the playback section selection unit 81 selects a section A1 used as an intro among the base music A. Alternatively, the playback section selection unit 81 may randomly select a priority section from among all the songs selected by the user or unselected songs. In addition, the playback section selection unit 81 may select a section selected by the user as a priority section.

  Further, the playback section selection unit 81 may determine the section to be played back last from among the priority sections of the bass music. That is, the playback section selection unit 81 may select both the first and last sections of the composite music from the priority sections of the base music. In the example of FIG. 5A, the playback section selection unit 81 can select the section A6 that is the priority section of the base music A as the section to be played back last from the music data. The configuration information of section A6 indicates that section A6 is outro. That is, the playback section selection unit 81 can select the section A6 used as the outro from the bass music A.

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

  Further, the playback section selection unit 81 may select a priority section from the same music piece. In the example of FIG. 5A, the playback section selection unit 81 may select the section B6 that is the outro as the priority section that is located after the section B4 that is the chorus. Furthermore, the playback section selection unit 81 may select a priority section located before the selected priority section as a composition of the music, or may repeatedly select a section that has already been selected. For example, in the example of FIG. 5A, the playback section selection unit 81 may select the section B1 that is the intro or the section B4 that is the chorus as the priority section that is located after the section B4 that is the chorus.

[Select Connection Section]
Next, the connection section selection unit 82 selects a connection section having good compatibility with the priority section from the music data based on the reference information, that is, referring to the compatibility as the compatibility information. Specifically, the connection section selection unit 82 selects, based on the compatibility, the preceding section that precedes the section B4 that has already been selected as the priority section, and the subsequent section that follows the section A4 that has already been selected as the priority section. At least one is selected from music data. In other words, the connection section selection unit 82 has at least a part of the connection section as one or two of the connection sections including two sections, or one or two of the connection sections including three or more sections. Select one. The connection section is arranged in the synthesized music so that at least a part thereof is located between the priority sections.

  First, the connection section selection unit 82 extracts a section that is compatible with the already selected priority section as a candidate section of the subsequent 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 of the subsequent section. Further, the connection section selection unit 82 extracts sections B2, B3, and B5 that are compatible with the already selected section B4 as candidate sections of the preceding section. By selecting a section that constitutes a connection section from among these candidate sections, the connection section selection unit 82 can select a connection section that is compatible with the priority section.

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

  Subsequently, the connection section selection unit 82 extracts a combination having a point of easy connection from a combination of the priority section and the connection section having a predetermined threshold value or more. And the connection section selection part 82 selects one combination at random from the extracted combination pattern. Thereby, the connection section selection part 82 can select the connection section which precedes or follows the section which should be selected as a connection section. In the example of FIG. 5B, the combination of sections A1, A2, B3, and B4 has a compatibility of 100 points between sections A1 and A2, a compatibility of 100 points between sections A2 and B3, and a compatibility between sections B3 and B4. It becomes the compatibility degree of 300 points which added 100 points. When the threshold is set to 250 points, in addition to this combination, a combination of sections A1, A2, B2 and B4 (250 points) and a combination of sections A1, A3, B3 and B4 (250 points) Extracted. 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 indicating the highest point from 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 the sections A2 and B3 included in the combination as connection sections.

  Furthermore, the connection section selection unit 82 may refer to the attribute information when creating the composite music. For example, the connection section selection unit 82 may exclude a section associated with attribute information indicating that it cannot be used as an intro when selecting the first priority section of the synthesized music. Furthermore, the connection section selection unit 82 may refer to at least one of key information and code information as compatibility information. For example, the connection section selection unit 82 can select a section having a key for the priority section as a connection section having good compatibility with the priority section. In addition, the connection section selection unit 82 can select a section having a chord progression similar to that of the priority section as a connection section having good compatibility with the priority section.

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

  Further, the connection section selection unit 82 may select a section other than the section constituting the music selected by the user as the connection section. For example, the connection section selection unit 82 repeats a section of a music piece that is not selected by the user, an effect sound section that reproduces an effect sound according to the user's operation, a section that includes sound effects such as beat sounds, and a part of the music piece. A loop section, a general-purpose section created in advance for a connection section, a specific section created in advance for a connection section of a specific music piece, or the like may be selected as the connection section.

  Such a game program 42 of the game machine 10 is based on reference information that is used to select a priority section that is associated with each of the plurality of sections and to be included in the synthesized music by the control unit 30 as a computer. , And function as playback section selection means for selecting a priority section from the music data. Further, the game program 42 causes the control unit 30 to function as a connection section selection unit that selects, from the music data, a connection section to be positioned between the priority sections based on the reference information.

  Note that when two sections are connected, the music creation unit 80 may change at least one of the last part of the preceding section and the first part of the subsequent section. For example, the music creation unit 80 may perform at least one of fade-out that gradually decreases the volume of the preceding section and fade-in that gradually increases the volume of the subsequent section. Furthermore, the music creation unit 80 may emphasize the high frequency range by cutting out the low frequency range of at least one of the preceding section and the subsequent section, or may emphasize the low frequency range by deleting the high frequency range. Furthermore, the music creation unit 80 may insert a sound effect or an effect music into at least one of the last part of the preceding section and the first part of the succeeding section. Moreover, the music creation unit 80 may change the section so that only a part of the section, for example, only a part of the sub-musical section is reproduced.

[Create musical score data]
As shown in FIG. 4, the music creation unit 80 of the control unit 30 includes a music score data creation unit 84 that creates musical score data of a composite music. For example, the musical score data creation unit 84 reads musical score data corresponding to the sections constituting the synthesized music from the memory 40 and arranges them according to the order of the sections, thereby creating musical score data of the synthesized music. 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 includes, for example, musical score data corresponding to a production 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 are stored. The musical score data creation unit 84 may use at least one of these musical score data instead of the musical score data corresponding to the section. Note that the music score data is created for each section, but there may be a plurality of sets of music score data corresponding to the difficulty level for one section.

[Selecting the production sound section]
As shown in FIG. 4, the music piece creation unit 80 of the control unit 30 includes an effect sound section determination unit 85 as effect sound section determination means. Furthermore, the reproduction control unit 60 of the control unit 30 includes an effect sound reproducing unit 61 as effect sound reproducing means. Hereinafter, with reference to FIGS. 6A to 6D, description will be given of a case where the effect sound section determination unit 85 inserts an effect sound section as a section connecting two sections of the synthesized music.

  The effect sound is a sound that is reproduced when the user performs a predetermined effect operation according to an operation procedure corresponding to the score data corresponding to the effect sound section (hereinafter referred to as “effect score data”). The effect sound section is associated with reference information that is referred to in order to specify the effect sound. Further, the effect sound reproduction unit 61 reproduces the effect sound according to the effect operation when the user performs a predetermined effect operation. In addition, there are an effect sound section in which only the effect sound is reproduced and an effect sound section in which a sound effect such as music or bass sound is reproduced in addition to the effect sound. Furthermore, in the case of the effect sound section in which music or sound effects are reproduced, the effect sound reproducing unit 61 reproduces music or sound effects in addition to the effect sound according to the user's effect operation. The performance score data is, for example, a length of one measure (four beats), and is configured such that one or more objects are guided. The production score data may be created in advance, or may be automatically created by the music creation unit 80.

  In the example of FIG. 6A, the effect sound section determination unit 85 inserts the effect sound section between the section B4 as the priority section and the section A2 as the connection section. The effect sound section determination unit 85 may determine the effect sound section so that the effect sound is reproduced simultaneously with at least a part of the section of the music. Even in the case where the effect sound section is inserted in this way, since the tune changes depending on the effect sound, the effect sound section is used to connect the two sections. In the example of FIG. 6B, the effect sound section determination unit 85 determines the effect sound section so that the effect sound is reproduced simultaneously with the last part of the section A2 as the connection section. In the example of FIG. 6C, the effect sound section determination unit 85 determines the effect sound section so that the effect sound is reproduced simultaneously with the first part of the section B4 as the priority section. Furthermore, in the example of FIG. 6D, the effect sound section determination unit 85 determines the effect sound section so that the effect sound is reproduced over the section B3.

  Specifically, the guide unit 71 guides the user to the operation procedure of the production operation according to the production music data corresponding to the production sound section. For example, the guide unit 71 guides the operating procedure of the rendering operation to the user by the rendering object 24 or the line object 25 in FIG. The user operates the effect button 17 or the rotation device 18 of the operation unit 14 according to the guided operation procedure of the rendering operation. Then, the effect sound reproduction 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 effect sound reproducing unit 61 reproduces the effect sound as set in the effect sound section. On the other hand, when the user performs an incorrect operation, the effect sound reproduction unit 61 does not reproduce the effect sound or reproduces the incorrect effect sound according to the user operation.

  Here, the user's performance operation may or may not be score addition target. If it is set as an addition target, it becomes a motivation for the user to reproduce the production sound, and the user can maintain a sense of tension until the next section. If not subject to addition, the user can be given the option of not performing the rendering operation, and the user can arrange the music to be played.

  The effect sound section determination unit 85 determines an effect sound section for connecting at least two sections, for example, priority sections, priority sections and connection sections, or connection sections. For example, a production sound section is automatically determined as a connection between sections of a synthesized music piece. As an example, the effect sound section determination unit 85 determines whether or not to randomly insert an effect sound section when the connection section selection unit 82 selects a connection section or after selecting a connection section. When it is determined that the effect sound section is to be inserted, the effect sound section determining unit 85 inserts the effect sound section between arbitrary sections. Further, the effect sound section may be inserted in the first part of the section or the last part 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 music tone information indicating keys, volume, tempo, etc. representing the music to be inserted. . The effect sound section determination unit 85 may extract and select effect sound sections having good compatibility with the sections before and after inserting the effect sound section. Alternatively, the effect sound section determination unit 85 may select an automatically generated effect sound section. For example, the effect score data of the effect sound section that is automatically generated may be data in which an object is guided at random, or data in which an object is guided in a pattern based on the tune information of the base music or sub music. Also good. Note that the tune information is determined in advance for each tune and stored in the memory 40 or the like.

  In addition, when there is a production sound section corresponding to all the music pieces and a production sound section corresponding to the specific music piece, the production sound section determination unit 85 causes the production sound to be inserted only into the corresponding music piece. Select a section. Further, the effect sound section determination unit 85 may be inserted so that a plurality of effect sound sections are continuous, or may be inserted so that the same effect sound section is continuous. However, the effect sound section determination unit 85 inserts the effect sound section associated with the reference information indicating the rule of inserting alone so as not to be continuous.

  Alternatively, the production sound section determination unit 85 inserts a production sound section between the 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. To do. The effect sound section determination unit 85 may determine the effect sound section with reference to attribute information as reference information. For example, if the attribute information indicates that the effect sound section can be connected to the end of the section, the effect sound section determining unit 85 inserts the effect sound section so as to follow the end of the section. When the attribute information indicates that the effect sound section can be connected at the beginning of the section, the effect sound section determination unit 85 inserts the effect sound section so as to precede the section.

  When inserting the effect sound section, the score data determining unit reads the effect score data corresponding to the effect sound section from the memory 40, and synthesizes the other score data and the effect score data according to the order of the sections. Create musical score data. In the example of FIG. 6A, the musical score data determination unit arranges the production musical score data between the section A2 and the section B4. Therefore, the guidance means guides the operation procedure of the rendering operation between the two sections. Then, when the user correctly performs the game operation in accordance with the production operation, the production sound reproduction unit 61 reproduces the production sound set in the production sound section.

  The musical score data determination unit may arrange the musical score data together with the musical score data corresponding to the section of the music. That is, the musical score data determination unit may arrange the production musical score data so as to overlap the section of the music. In the example of FIG. 6B, the musical score data determination unit arranges the production musical score data so as to overlap with the last part of the musical score data corresponding to the section A2. In the example of FIG. 6C, the musical score data determination unit arranges the production musical score data so as to overlap the first part of the musical score data corresponding to the section B4. Furthermore, in the example of FIG. 6D, the musical score data determination unit arranges the production musical score data so as to overlap the entire musical score data corresponding to the section B3. When the performance score data is arranged in this way, the guide means performs 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 after the two sections. The operation procedure of the operation is guided.

  In addition, the connection section selection part 82 can also select an effect sound section as a connection section based on the compatibility information as reference information. In this case, the connection section selection unit 82 functions as the effect sound section determination unit 85.

  Such a game program 42 of the game machine 10 causes the control unit 30 as a computer to function as reproduction section selection means for selecting at least two sections to be included in the synthesized music from the music data. Further, the game program 42 causes the control unit 30 to function as effect sound section determining means for determining an effect sound section for connecting at least two sections. Further, the game program 42 causes the control unit 30 to function as effect sound reproducing means for reproducing effect sound according to the effect operation when the user of the game performs a predetermined effect operation. The game program 42 is a guide means for guiding the operation procedure of the game to the user, and guides the operation procedure of the rendering operation according to the musical score data corresponding to the performance sound section. To function as.

  When such a game machine 10 generates a synthesized music piece, a production sound section can be inserted between connected sections. Thereby, even if the keys, volume, or tempo of the connected sections are different, it is possible to maintain the integrity of the synthesized music and eliminate the user's uncomfortable feeling. That is, if the connected sections have different keys, volume, or tempo, for example, the user will be confused if at least some of them are suddenly changed. Therefore, by inserting the production sound section, it is possible to eliminate the uncomfortable feeling when connecting the sections. Further, even if the connected sections have similar keys, volume, or tempo, it is possible to create unity as a composite music piece.

  Moreover, the sections of music can be connected to each other by the effect sound reproduced by the user performing the effect operation. Therefore, it is possible to give the user an experience that he / she arranges the synthesized music. Furthermore, the user feels that the connected sections are smoothly connected to each other by reproducing the effect sound that is compatible with the connected sections. Therefore, it is possible to connect the two sections so that the unity as the composite music is maintained. Thereby, the synthetic music which a user does not feel discomfort can be created.

[Simultaneous section playback]
As shown in FIG. 4, the reproduction control unit 60 of the control unit 30 includes a simultaneous reproduction unit 62 as a simultaneous reproduction unit that reproduces at least a part of two sections, for example, two connection sections simultaneously. Specifically, the simultaneous playback unit 62 plays back at least some of these sections simultaneously when at least two of the connected sections satisfy a predetermined condition. The 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 the keys of both sections, the chord progression of both sections being similar, the tempo of both sections being the same, the length of both sections being the same, etc. This may be a predetermined condition. Hereinafter, simultaneous reproduction will be described with reference to FIGS. 7A to 7C.

  When the simultaneous playback unit 62 determines that the predetermined condition is satisfied, the simultaneous playback unit 62 simultaneously plays back two connected sections randomly. For example, when section A2 and section B3 are selected as connection sections, the simultaneous playback unit 62 determines whether or not the sections A2 and B3 can be played back simultaneously. When it is determined that simultaneous playback is possible, the simultaneous playback unit 62 determines whether to play back simultaneously at random. Alternatively, the simultaneous playback unit 62 may determine to perform simultaneous playback when referring to the attribute information and indicating that simultaneous playback is possible. If it is determined that simultaneous playback is performed, the simultaneous playback unit 62 arranges the sections so that the sections A2 and B3 are played back simultaneously as shown in FIG. 7A. The determination as to whether or not to perform simultaneous playback may be performed after the connection section selection unit 82 extracts a section that precedes or follows a candidate section to be selected as a connection section.

  Further, the simultaneous playback unit 62 may play back part of the two sections simultaneously. In the example of FIG. 7B, a part of section A2 and a part of section B3 are reproduced simultaneously. The simultaneous playback unit 62 may repeatedly play back two sections simultaneously. In the example of FIG. 7C, section A2 and section B3 are repeatedly reproduced simultaneously. Thereby, even if it reproduces simultaneously, it can prevent that the length of a synthetic music changes. Note that the simultaneous reproduction unit 62 may simultaneously reproduce at least a part of three or more sections.

  Alternatively, the simultaneous playback unit 62 may play back priority sections or priority sections and connected sections simultaneously. In addition to the section obtained by dividing the music data of the music, the music data is created corresponding to the effect sound section consisting of the effect sound according to the user's operation, the section consisting of the sound effect, and the specific music. In addition, other sections such as a section that repeatedly loops a sound of a predetermined length and a section that is created for an unspecified music and repeatedly loops a sound of a predetermined length may be included. In this case, the simultaneous playback unit 62 may play back the priority section or connection section and another section at the same time.

  In the case of simultaneous reproduction, the musical score data creation unit 84 assigns musical score data corresponding to one of the two connection sections to the simultaneous reproduction portion, that is, two connection sections that are simultaneously reproduced. In the example of FIG. 7A, the musical score data creation unit 84 assigns musical score data corresponding to the section A2 among the sections A2 and B3 that are reproduced simultaneously. In addition, the musical score data creation unit 84 may assign musical score data corresponding to the section that has been started to be reproduced until the simultaneous reproduction ends, that is, until the section is switched, in the two connected sections that are simultaneously reproduced. In the example of FIG. 7B, the musical score data creation unit 84 assigns the musical score data of the section A2 that has been started to be reproduced during simultaneous reproduction. And when section A2 switches to section B3, the musical score data corresponding to the remaining part except the simultaneous reproduction part among the musical score data corresponding to section B3 are allocated.

  Furthermore, in the case of simultaneous reproduction, the music creation unit 80 may emphasize the high frequency range by cutting out the low frequency range of at least one of the sections to be reproduced simultaneously, or may emphasize the low frequency range by deleting the high frequency range. For example, the music creation unit 80 emphasizes the low frequency range by cutting the high frequency range of the sub-musical section. Thereby, it is possible to emphasize the base music more than the sub music in the simultaneously reproduced sections. Further, at least one of the sections to be reproduced simultaneously may be changed based on the sound quality, the sound source, or the instrument type. For example, one section may be changed to include only a song or only a bass sound. Note that it is possible to change all the sections to be simultaneously played. When the last part of the preceding section and the first part of the subsequent section are played back simultaneously, the music creation unit 80 may change at least one of the last part and the first part. For example, the music creation unit 80 may perform at least one of fade-out that gradually decreases the volume of the preceding section and fade-in that gradually increases the volume of the subsequent section. Furthermore, the music creation unit 80 may insert a sound effect or an effect music into at least one of the last part of the preceding section and the first part of the succeeding section. Further, the music creation unit 80 may change the section so that only one of the sections to be played simultaneously, for example, only a part of the section of the sub-music is played.

  When assigning musical score data corresponding to one of the two connected sections, the musical score data creating unit 84 may assign musical score data corresponding to any section of the base music and the sub music. In the example of FIG. 7A, the musical score data creation unit 84 assigns musical score data corresponding to the section A2 of the base music A. On the other hand, in the example of FIG. 7C, the musical score data creation unit 84 assigns musical score data corresponding to the section B3 of the sub-music B.

  As a result of the musical score data being assigned in this way, when the simultaneous reproduction unit 62 performs simultaneous reproduction, the guidance means allows the user to perform an operation procedure according to the musical score data corresponding to one of the two connected sections in the simultaneous reproduction portion. invite. Alternatively, the guidance means may randomly select one of the musical score data corresponding to the two connected sections in the simultaneous reproduction portion, and guide the user to the operation procedure corresponding to the selected musical score data. In this case, the musical score data creation unit 84 sets two musical score data in association with sections to be reproduced simultaneously.

  Further, the connection section selection unit 82 may select an additional connection section from 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 the section B2 from the candidate sections and connects it after the simultaneous playback portion.

  By simultaneous playback, the user feels that connected sections are smoothly connected. Therefore, it is possible to connect the two sections so that the unity as the composite music is maintained. Thereby, the synthetic music which a user does not feel discomfort can be created.

[Synthetic music creation flow]
A composite music creation flow will be described with reference to the flowchart of FIG. First, the control unit 30 determines whether or not the user has selected the composite music mode. If the composite music mode is not selected, no composite music is created. On the other hand, if the composite music mode is selected, the music creation unit 80 determines the section of the base music and the section of the sub music (S601). Then, the playback section selection unit 81 determines a priority section to be played back first in the synthesized music (S602). Further, the playback section selection unit 81 selects the next priority section from the music pieces 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. When the predetermined condition is satisfied (YES in S604), the connection section selection unit 82 determines whether the priority section between the succeeding section that follows the priority section to be reproduced first and the priority sections are based on the compatibility information. The preceding section preceding the priority section to be reproduced later is selected as at least a part of the connection section from the music data. For this purpose, the connection section selection unit 82 extracts a section that is compatible with the already selected priority section as a candidate section of the subsequent section or the preceding section (S605).

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

  Subsequently, the connection section selection unit 82 extracts a combination having a compatibility degree equal to or higher 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 a section included in the selected combination as a connection section. In this way, the connection section selection unit 82 selects a connection section having good compatibility with the priority section from the music data.

  Thereafter, the effect sound section determination unit 85 randomly determines whether or not to insert the effect sound section between the sections (S608). If it is determined to insert the effect sound section (YES in S608), the effect sound section determination unit 85 inserts the effect sound section between any sections (S609). The effect sound section may be inserted after the connection section selection unit 82 extracts a section that precedes or follows 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 in which the effect sound sections are inserted. Then, the connection section selection unit 82 selects a section included in the selected combination as a connection section.

  Subsequently, the simultaneous playback unit 62 determines whether or not two consecutive sections can be played back simultaneously. If it is determined that simultaneous playback is possible, the simultaneous playback unit 62 determines whether or not to simultaneously playback the two sections at random (S610). When it is determined that simultaneous playback is to be performed (YES in S610), the simultaneous playback unit 62 arranges the sections so that at least a part of the two sections are played back simultaneously (S611). The determination as to whether or not to perform simultaneous playback may be performed after the connection section selection unit 82 extracts a section that precedes or follows a candidate section to be selected as a connection section.

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

  By creating the composite music as described above, the playback section selection unit 81 can select the connection section connected to the priority section so that the unity as the composite music is maintained. Furthermore, the connection sections can be connected to the priority sections in an order that maintains the unity as a composite music piece. Thereby, in consideration of the overall composition of the composite music, it is possible to create a composite music that the user does not feel uncomfortable.

[Highlighting]
When simultaneously playing sections of different music pieces, the user audibly discriminates which music piece is being played, which may make it difficult to distinguish the music piece. Therefore, in order to indicate which music is being played, as shown in FIG. 4, the display control unit 50 of the control unit 30 includes a music specifying unit 51 as a music specifying unit and a superior section as a dominant section discriminating unit. It has a determination unit 52 and an emphasis display unit 53 as an emphasis display means.

  The music specifying unit 51 functions so as to indicate to the game user a specific display that specifies each of a plurality of music pieces including sections being played simultaneously, for example, two music pieces. For example, the music specifying unit 51 displays each specific display (for example, an icon) on the monitor 12. In addition, the superior section determination unit 52 determines at least one superior section that is superior to other sections among the sections being reproduced simultaneously. For example, the superior section discriminating unit 52 is a section in which an operation procedure according to the corresponding musical score data is guided to the user (a section in which the guide unit 71 guides the operation procedure), or a section whose playback volume is larger than other sections. And a section corresponding to at least one of the sections started to be played after the other sections are determined to be superior sections. In the following, a case where a section with a high reproduction volume is the dominant section will be described.

  Based on the discrimination result of the superior section discriminating unit 52, the highlighting display unit 53 displays the superior section specific display relatively emphasized relative to the specific display of the other sections. This highlighting will be described with reference to FIGS. In FIG. 9, a base music icon 29 </ b> A for specifying the base music A and a sub music icon 29 </ b> B for specifying the sub music B are displayed above the plurality of lanes 22. The superior section discriminating unit 52 discriminates which section of the musical composition is dominant when sections of a plurality of musical compositions are reproduced simultaneously. In FIG. 9, the base music A and the sub music 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, the playback control unit 60 lowers the volume of one music piece as the game progresses, and makes it lower than the volume of the other music piece. In this case, the superior section discriminating unit 52 discriminates the section of the music having a large reproduction volume as the superior section. In the example of FIG. 10, the playback volume of the sub-music B is larger than that of the base music A. 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. Thereby, it can be shown to the user that the section of the sub-music B is being played.

  Further, the highlighting unit 53 may determine the size ratio of the icons in accordance with the volume ratio of the playback volume of the songs. For example, when 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 1.5 times that of the base music icon 29A. . Alternatively, the highlighting unit 53 may increase the icon size difference as the reproduction volume difference between songs increases.

  Further, when the specific display is an image, the highlighting unit 53 displays at least one of the color, hue, brightness, contrast, density, and display pattern of the image in addition to the image size or in addition to the image size. It may be changed. When the specific display is other than an image, the emphasis by the emphasis display unit 53 is, for example, a mode such as a change in the background color ratio, a change in the background color, hue, brightness, contrast, and density, and a blinking background color. May be. Further, in order to emphasize and display the icon of the superior section relatively, the highlighting unit 53 may display the icon of the section that is not the dominant section in a weak tone. For example, the emphasis display unit 53 may perform a weak display in such a manner that the other image is made smaller, the color of the other image is made light, and the other image is blinked. Furthermore, the highlighting unit 53 may perform highlighting in such a manner that, for example, the image is gradually enlarged, the image is gradually darkened, and the blinking cycle of the image is gradually changed in order to highlight gradually. .

  Further, when simultaneously playing three or more music sections, the superior section determination unit 52 determines and highlights at least one section as an advantageous section. When the superior section determination unit 52 determines that a section whose playback has started after another section is the superior section, the guide unit 71 performs an operation procedure according to the musical score data corresponding to the superior section. The user may be guided. For example, when assigning musical score data corresponding to one of the two connected sections, the musical score data creating unit 84 may assign musical score data corresponding to the dominant section to the simultaneous reproduction portion. Thereby, the guidance part 71 will guide the user the operation procedure according to the musical score data corresponding to the dominant section.

  Such highlighting can effectively convey the music being played to the user and the audience watching around the user. Furthermore, by displaying a size specifying display according to the volume ratio of the playback volume, it is possible to inform the user and the audience of what kind of music is being played and at what level.

  Such a game program 42 of the game machine 10 causes the control unit 30 as a computer to function as simultaneous playback means for simultaneously playing at least a part of at least two sections of two music sections. In addition, the game program 42 causes the control unit 30 to function as music specifying means for indicating to the game user a specific display that specifies each of a plurality of music pieces including sections being played simultaneously. Furthermore, the game program 42 causes the control unit 30 to function as superior section discrimination means for discriminating at least one superior section that is superior to other sections among the sections being played simultaneously. In addition, the game program 42 displays the control unit 30 as a highlight display unit that emphasizes and displays the specific display of the superior section relative to the specific display of the other sections based on the determination result of the superior section determination unit. Make it work.

  The present invention has been described above with reference to each embodiment. However, the present invention is not limited to the above embodiment. Inventions modified within the scope not departing from the present invention and inventions equivalent to the present invention are also included in the present invention. Moreover, each embodiment and each modification can be combined suitably in the range which is not contrary to this invention.

  For example, there may be one connection section. Furthermore, when 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 a priority section as a connection section.

  The compatibility information may further include tempo information indicating the tempo of the section or length information indicating the time length of the section. In this case, the connection section selection unit 82 may select a section having the same tempo as the priority section or a section having the same time length as a connection section that is easily connected. Furthermore, the connection section selection unit 82 may add or subtract the compatibility point with reference to at least one of the tempo information and the length information. Furthermore, the connection section selection unit 82 may select a connection section after the keys of the sections are aligned. Thereby, the choice of the connection section which is easy to connect can be increased, and many types of synthesized music can be created.

  Further, the playback section selection unit 81 may select a priority section constituting the composite music after determining the composition of the composite music. As an example, the playback section selection unit 81 refers to the configuration information of the priority section of the base music and determines the configuration of the base music as the composition of the synthesized music. For example, when the priority section of the bass music has configuration information indicating the configuration of intro, chorus, and outro, the playback section selection unit 81 synthesizes the configuration including intro, chorus, and outro in this order. It is determined as the composition of the music.

  Alternatively, when the bass music includes intro, A melody, B melody, chorus 1, interlude, chorus 2 and outro in this order, the playback section selection unit 81 sets the intro, chorus 1, chorus 2, and outro. The priority section having the configuration information indicating the configuration is selected from the base music section or the sub music section. And the connection section which has the structure information which shows the structure of A melody, B melody, and an interlude is selected from the section of a base music or a sub music. After that, the playback section selection unit 81 arranges the priority section and the connection section so that they are arranged in the order of intro, A melody, B melody, chorus 1, interlude, chorus 2, and outro.

  Thereby, since the whole structure of a synthetic music coincides, the balance of music composition can be maintained. Note that the playback section selection unit 81 may determine the composition of the composite music based on the composition of the music selected first or last by the user, for example, instead of the base music.

  Further, when simultaneously reproducing the last part of the preceding section or the first part of the succeeding section with another section, the simultaneous reproducing unit 62 may perform simultaneous reproduction for a time corresponding to a predetermined number of bars. For example, the simultaneous playback unit 62 may play back simultaneously for a time corresponding to one bar, two bars, four bars, or eight bars.

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

  The music creation unit 80 may create a composite music from one base music and two or more sub-music as a section of three or more music. For example, when creating a composite music piece from the base music piece A, the sub music piece B, and the sub music piece C, in addition to the sections shown in FIG. 5A, six sections C1, obtained by dividing the sub music piece C1, A priority section and a connection section are selected from C2, C3, C4, C5 and C6.

  Further, the connection section selection unit 82 may select a section that is a priority section as a connection section. In this case, a priority section that follows the preceding priority section is arranged continuously. For example, the section B4 of the sub-music B can be arranged behind the section A1 of the bass music A. Furthermore, the connection section selection unit 82 selects a connection section to be located between the section B4 which is a priority section and another priority section subsequent to the section B4 from the music data.

  Moreover, the connection section selection part 82 may select a priority section as a connection section. In this case, the priority section selected by the playback 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 the section A1 that is the priority section, and the connection section selection unit 82 may select the section A1 as the connection section that follows. Thereby, since section A1 is reproduced continuously, the length of the synthesized music can be adjusted.

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

  Hereinafter, various aspects derived from the above-described embodiments and modifications will be described. In addition, in order to make an understanding of each aspect easy, the reference numerals illustrated in the attached drawings are appended in parentheses. However, the reference numerals are not added with the intention of limiting the present invention to the illustrated embodiments.

  The game system 10 selects these sections from the music data including a plurality of sections obtained by dividing a plurality of music pieces into a plurality of sections, and selects the synthesized music by selecting these sections. In the game system 10 to be created, a playback section selection means 81 for selecting at least two sections to be included in the synthesized music from the music data, and an effect sound section for connecting the at least two sections The effect sound section determining means 85 to be determined, the effect sound reproducing means 61 for reproducing the effect sound according to the effect operation when the game player performs a predetermined effect operation, and the operation procedure of the game to the player. Guiding means 71 for guiding according to the musical score data corresponding to the effect sound section , And a guide means 71 for guiding the operation procedure of the staging operation.

  With this game system, it is possible to eliminate the uncomfortable feeling when inserting the effect sound sections and connecting the sections together. In addition, when creating a synthesized music piece, sections other than the effect sound section can be connected by a known method. For example, a section corresponding to chorus may be selected from the music pieces selected by the player, and the selected sections may be connected at random.

  The effect sound section determination 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 the compatibility with other sections. Thereby, the uncomfortable feeling of the player can be solved while maintaining the integrity of the synthesized music.
