<Overall configuration of ensemble system>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of an ensemble system according to the present embodiment. This system is composed of a plurality of wireless terminals 10, 10,.

  One of the plurality of wireless terminals 10, 10... Is set as the host terminal 10H. The wireless terminals 10 other than the host terminal 10H operate as the client terminal 10C. In the example of FIG. 1, an ensemble system is composed of one host terminal 10H and four client terminals 10C1, 10C2, 10C3, and 10C4.

  In the following description, the host terminal 10H and the client terminal 10C are not particularly distinguished, and the common function and property are collectively referred to as the wireless terminal 10 when describing them. Further, the client terminals 10C1 to 10C4 are not particularly distinguished from each other, and will be collectively referred to as the client terminal 10C when common functions and properties are described.

  The host terminal 10H and the client terminal 10C are terminals having the same role in that they play the performance parts they are in charge of, but have different roles for setting the operation of the system.

  The host terminal 10H and the client terminal 10C are terminals that can be operated by the user. In the example of FIG. 1, one user has the host terminal 10 </ b> H, and the subsequent four users operate the client terminals 10 </ b> C <b> 1 to 10 </ b> C <b> 4 respectively. The five users can enjoy the ensemble indoors and outdoors. In some cases, the five users can feel as if they are playing as a rock band, and in other cases, they can feel as if they are playing an orchestra. Yes.

<Configuration of wireless terminal>
FIG. 2 is a functional block diagram of the wireless terminal 10. That is, it is a functional block diagram common to the host terminal 10H and the client terminal 10C. As shown in the figure, the wireless terminal 10 includes a control unit 100, an operation unit 101, a speaker 102, an LED light emitting unit 103, a monitor 104, a storage unit 105, and a wireless unit 106.

  The control unit 100 includes a CPU, a RAM, and the like, and performs overall control of the wireless terminal 10. The control unit 100 also includes an audio playback unit 110. The sound reproducing unit 110 reproduces the performance sound based on the performance information PI stored in the storage unit 105. The performance sound reproduced by the sound reproducing unit 110 is output from the speaker 102.

  As shown in FIG. 1, the operation unit 101 includes a plurality of touch buttons. The operation unit 101 may include a numeric keypad, a dial, a joystick, and the like in addition to the touch buttons. The user of the wireless terminal 10 performs a performance operation by operating the operation unit 101. The operation unit 101 may be realized by an acceleration sensor. That is, when the user performs operations such as shaking the radio terminal 10 up and down, shaking left and right, twisting, pushing forward, and pulling backward, this operation is detected by the acceleration sensor, and the operation unit 101 performs this operation. Is input as a performance operation. If a three-axis acceleration sensor is used as the acceleration sensor, the movement of the wireless terminal 10 in the XYZ directions can be detected. Under the control of the control unit 100, the LED light emitting unit 103 turns on LED light for guiding the performance timing by the user. The monitor 104 is used for various information displays such as system setting operation information and performance score display. Moreover, it is used also for the use which performs the graphical display for guiding the performance timing by a user. The wireless unit 106 performs wireless communication between the wireless terminals 10. As wireless communication, for example, Zigbee, Bluetooth, wireless LAN, or the like can be used.

<Performance information and performance timing>
Next, the contents of the performance information PI will be described. The performance information PI is information corresponding to the performance part assigned to each wireless terminal 10 and is information describing the musical instrument sound played by each wireless terminal 10. For example, MIDI data can be used as the performance information PI. That is, the performance information PI includes score information. The sound reproducing unit 110 can reproduce the performance sound according to the performance information PI. When MIDI data is used as the performance information PI, the audio playback unit 110 has MIDI sound source data.

  However, in the present embodiment, the sound reproducing unit 110 outputs the performance sound to the speaker 102 when the performance operation by the user matches the performance timing described in the performance information PI.

  First, the audio reproduction unit 110 reproduces a performance sound based on the performance information PI, and sends a light emission instruction to the LED light emission unit 103 in accordance with the performance timing. Alternatively, a graphical display showing performance timing is performed on the monitor 104. Thus, the LED originally emits light at the timing when the performance sound is reproduced based on the performance information PI. Alternatively, a graphical display is performed on the monitor 104 at the timing when the performance sound is reproduced.

  In addition, the audio reproduction unit 110 detects a performance operation using the operation unit 101 by the user. When the light emission timing of the LED matches the performance timing of the user, or when the display timing of the graphical display on the monitor 104 matches the performance timing of the user, the performance sound is sent to the speaker 102 based on the performance information PI. It outputs. On the other hand, when the LED light emission timing or the graphical display timing does not match the performance timing by the user, the sound reproducing unit 110 does not output the performance sound to the speaker 102. That is, if the user performs a correct performance operation, the performance sound is reproduced from the speaker 102.

  Thus, in the present embodiment, when the audio reproduction unit 110 “reproduces the performance information PI”, the instrument sound is not always output from the speaker 102. The sound reproducing unit 110 performs at least LED display and graphical display indicating performance timing by “reproducing the performance information PI”. When the guide display matches the timing of the performance operation by the user, the musical instrument sound is output from the speaker 102 for the first time.

<Concert information>
As described above, the performance information PI is information for each performance part assigned to each wireless terminal 10. The set of performance information PI is ensemble information SI. That is, the ensemble information SI is information describing all the performance information PI of all performance parts.

  As shown in FIG. 3, the ensemble information SI is downloaded from the music server 20 by the host terminal 10H via the Internet. Then, the host terminal 10H transfers the performance information PI included in the ensemble information SI to each of the client terminals 10C1 to 10C4. At this time, the host terminal 10H refers to the header information SIH included in the ensemble information SI, determines performance parts to be assigned to the client terminals 10C1 to 10C4, and transfers performance information PI corresponding to the performance parts. .

  The ensemble information SI includes header information SIH together with a set of performance information PI. FIG. 4 is a diagram showing the description content of the header information SIH. The header information SIH describes rules for how performance parts are allocated according to the number of wireless terminals 10 participating in the ensemble system.

  In the example shown in the figure, the musical piece described by the ensemble information SI is composed of five performance parts from the track T1 to the track T5. Therefore, the ensemble information SI includes performance information PI corresponding to these tracks T1 to T5.

  Of these, the track T1 is an accompaniment performance part. For example, the accompaniment performance part may be reproduced on the host terminal 10H. Tracks T <b> 2 to T <b> 4 are performance parts assigned according to the number of wireless terminals 10. The track T5 is a part that all the wireless terminals 10 perform based on a predetermined rule.

  In the example shown in the figure, if there are two wireless terminals 10 participating in the ensemble system, the track T2 is assigned to the wireless terminal 10 with ID = 1, and ID = 2 It is stipulated that the track T3 is assigned to the wireless terminal 10 of In this case, since there is no wireless terminal 10 that plays the track T4, it is specified that the track T4 is also assigned to the part of the accompaniment performance. Therefore, for example, the track T1 and the track T4 may be reproduced as accompaniment performances at the host terminal 10H. Regarding this accompaniment performance, a reproduced sound is output from the speaker 102 regardless of whether or not the user performs a performance operation.

  If the number of wireless terminals 10 participating in the ensemble system is 3, the track T2 is assigned to the wireless terminal 10 with ID = 1, the track T3 is assigned to the wireless terminal 10 with ID = 2, and the ID = 3 is assigned to the track T4. In the host terminal 10H, the track T1 may be reproduced as an accompaniment performance.

  The ID of each wireless terminal 10 is set in the host terminal 10H. That is, the host terminal 10H allocates an ID to each wireless terminal 10 according to the number of wireless terminals 10 participating in the ensemble system. Then, the performance information PI corresponding to the assigned ID is wirelessly transferred to each wireless terminal 10. Normally, the host terminal 10H allocates an ID number including its own device. Therefore, ensemble can be enjoyed by all users who have the host terminal 10H and the client terminal 10C. Alternatively, the host terminal 10H may be positioned as a setting terminal, assign an ID only to the client terminal 10C, and reproduce the performance information PI only by the client terminal 10C.

  Also, since the track T5 is a performance part that is reproduced by all the wireless terminals 10, the host terminal 10H transfers the performance information PI corresponding to the track T5 to all the client terminals 10C.

  For the track T5, it is preferable to describe a rule in the header information SIH as to how each wireless terminal 10 shares the performance. For example, a rule that assigns the wireless terminal 10 for each note (musical scale) may be used. Or you may make it a rule which assigns a performance part to each radio | wireless terminal 10 in order as time passes. Or you may prescribe | regulate so that a performance part may be replaced at random.

<Processing flow of ensemble system>
First, users who use the ensemble system gather. For example, in the example shown in FIG. 1, five users gather in a room, a hall, etc., and each has a wireless terminal 10. The wireless terminal 10 possessed by one of them is set as the host terminal 10H. For example, by operating the operation unit 101 of any one of the wireless terminals 10, the wireless terminal 10 can be set as the host terminal 10H.

  Next, the user possessing the host terminal 10H operates the operation unit 101 to download the ensemble information SI from the music server 20. Alternatively, the wireless terminal 10 may include a memory card slot and take in the ensemble information SI using a memory medium.

  When the host terminal 10H downloads the ensemble information SI, the ensemble information SI is stored in the storage unit 105. Although only the performance information PI is shown in the storage unit 105 of the wireless terminal 10 shown in FIG. 2, the ensemble information SI is also stored in the storage unit 105 of the host terminal 10H as shown in FIG. As described above, the ensemble information SI includes performance information PI and header information SIH corresponding to each performance part.

  Next, the user of the host terminal 10H operates the operation unit 101 to activate the application program. The application program is a program for enjoying an ensemble between a plurality of terminals, and is stored in the ROM in the control unit 100. When this application program is activated, the host terminal 10H is set to the host communication mode. Also in other wireless terminals 10, the application program is activated by a user operation. However, since the other wireless terminal 10 is not set as the host terminal 10H, it is set to the client communication mode. Hereinafter, the operation by the application program will be described as simply the operation by the control unit 100.

  Next, the control unit 100 of the host terminal 10H performs wireless communication to search for a client terminal 10C that is in the vicinity and is set in the client communication mode. Then, a list of searched client terminals 10 </ b> C is displayed on the monitor 104. The user of the host terminal 10H operates the operation unit 101 to select a terminal to participate in the ensemble from the client terminals 10C displayed as a list. Thus, the user who participates in an ensemble determines.

  When a terminal to participate in the concert is selected, the control unit 100 of the host terminal 10H allocates an ID to the participating terminal. Subsequently, the control unit 100 of the host terminal 10H refers to the header information SIH of the ensemble information SI and determines a track number to be assigned to each wireless terminal 10 to which the ID is assigned. Then, the control unit 100 of the host terminal 10H generates performance information PI corresponding to each track number from the ensemble information SI. The performance information PI corresponding to the assigned track number is transferred to each wireless terminal 10. In the example shown in FIG. 4, the performance information PI of track number T2 is transferred to the wireless terminal 10 assigned number 1 as the terminal ID, and the wireless terminal 10 assigned number 2 is assigned to the wireless terminal 10 assigned ID. Then, the performance information PI of the track number T3 is transferred.

  Next, the host terminal 10 transmits a synchronization offset confirmation signal to each client terminal 10C. Each client terminal 10C returns a response signal to the host terminal 10H in response to the received synchronization offset confirmation signal. The host terminal 10 determines the synchronization offset information of each client terminal 10C from the delay time of the response signal to the synchronization offset confirmation signal, and transmits the determined synchronization offset information to each client terminal 10C.

  When the synchronization offset information is set in each client terminal 10C in this way, subsequently, transmission of a synchronization signal from the host terminal 10H to each client terminal 10C is started. This synchronization signal is continuously transmitted to the client terminal 10C while the ensemble system is operating. The control unit 100 of each client terminal 10C adjusts the synchronization signal received from the host terminal 10H based on the set synchronization offset information. In this way, all the wireless terminals 10 are synchronized.

  Note that the above-described offset adjustment process is not necessary when accurate radio time information can be held, such as when each radio terminal 10 has a built-in radio clock. Each wireless terminal 10 may reproduce the performance information PI based on the absolute time held.

  While all the wireless terminals 10 are synchronized, a message such as “Ready. Press the start button.” Is displayed on the monitor 104 of the host terminal 10H. Here, the user of the host terminal 10H operates the operation unit 101 to instruct an ensemble start. In response to this operation, a performance start signal is transmitted from the host terminal 10H to each client terminal 10C, and synchronized playback of the performance information PI is started in each wireless terminal 10. That is, when each client terminal 10C receives the performance start signal, the client terminal 10C starts synchronous reproduction of the performance information PI according to the synchronization signal and the synchronization offset information.

  The audio reproduction unit 110 of each wireless terminal 10 performs a reproduction process of the performance information PI and sends an LED emission instruction to the LED emission unit 103 at the reproduction timing of the performance sound. Alternatively, a graphical display is performed on the monitor 104 at the playback timing of the performance sound. The user performs a performance operation by operating the operation unit 101 in accordance with the light emission timing or graphical display of the LED light emitting unit 103. When the performance timing described in the performance information PI matches the timing of the performance operation by the user, the playback sound of the instrument according to the performance information PI is output from the speaker 102. If the timing of the performance operation by the user deviates from the performance information PI, the playback sound is not output from the speaker 102.

  Thus, when the user participating in the ensemble performs a performance operation in accordance with the performance timing of each performance part, the musical instrument sound of each performance part is reproduced from each wireless terminal 10. For example, a bass sound is reproduced from the host terminal 10H, a guitar sound is reproduced from the client terminal 10C1, and a drum sound is reproduced from the client terminal 10C2. Thus, when each user performs a performance operation on each performance part accurately, it is possible to experience a band performance in a simulated manner.

  Alternatively, a piano sound is reproduced from the host terminal 10H, and instrument sounds such as a violin from the client terminal 10C1, a cello from the client terminal 10C2, and an oboe from the client terminal 10C3 are reproduced. Thereby, the user can experience an orchestra performance.

  In addition, the control unit 100 of each wireless terminal 10 sequentially determines whether or not the performance timing based on the performance information PI matches the timing of the performance operation by the user. Each time a performance operation is performed, the degree of matching of the performance timing is displayed on the monitor 104 as a score.

  FIG. 6 shows a state in which performance sounds are reproduced in synchronization with each wireless terminal 10. Then, at each performance timing, as shown in the figure, the control unit 100 determines performance points. This performance point is displayed on the monitor 104 every time a performance operation is performed. For example, an image as shown by a screen image 104A in the figure is displayed on the monitor 104. When the ensemble of one song is completed, the total score of the user is displayed on the monitor 104 at each wireless terminal 10. In this way, you can enjoy ensembles and compete for scores.

  When the ensemble of one song is completed, the total score of all participating users is totaled at the host terminal 10H, and the total score is displayed on the monitor 104 of each wireless terminal 10. As a result, a plurality of groups can challenge the same ensemble and compete for scores between groups.

  As described above, by using the ensemble system of the present embodiment, it is possible for a plurality of users to enjoy a performance with a sense of unity or to play by competing for scores in a group. In addition, unlike an actual musical instrument performance, the degree of freedom is high, so that various wireless terminals 10 can enjoy various ways such as playing a drum in one part of a song and playing a guitar in another part. .

  Further, when the number of participating wireless terminals is small, one wireless terminal 10 may be responsible for both the guitar and drum performance parts. This allows you to enjoy advanced techniques such as playing a large number of players alone.

  As described so far, this ensemble system allows each user to be in charge of different instruments, but of course, a plurality of users may be in charge of the same instrument. For example, a plurality of performance parts by the same musical instrument may be shared. Alternatively, each wireless terminal 10 may be in charge of a performance part for each scale. Thereby, the pseudo performance of the handbell orchestra can be enjoyed. That is, all the musical instruments are handbells, the host terminal 10H has a “do” sound, the client terminal 10C1 has a “le” sound, the client terminal 10C2 has a “mi” sound, and so on. A performance part for each scale is assigned. It has been described that an acceleration sensor may be used as the operation unit 101. If a performance operation interface using an acceleration sensor is used, the handbell orchestra can be experienced more realistically. A user to whom each scale is assigned can simulate an operation of ringing a handbell by shaking the wireless terminal 10 up and down.

<Modification>
In the above embodiment, at the start of the ensemble, the host terminal 10H acquires the number of wireless terminals 10 participating in the system, and the performance information PI to be assigned to each wireless terminal 10 is determined according to the number of terminals. . As another form, even in the middle of performance, when the number of wireless terminals 10 varies, the allocation of the performance information PI may be dynamically changed according to the number.

  That is, the control unit 100 of the host terminal 10H always searches for the number of client terminals 10C connected to the system. When the number of terminals increases or decreases, the header information SIH is referred to again to dynamically change the performance information PI assignment. Then, for example, after a predetermined time, the next measure is changed to an ensemble with a new performance part. Thereby, for example, a member can be added during performance.

  The performance information PI to be assigned may be determined according to the position of the terminal. For example, the host terminal 10H measures the strength of the radio signal between each client terminal 10C and estimates the distance to each client terminal 10C from the strength. Then, the performance part to be assigned is determined according to the distance. For example, a rule such as assigning a piano part to a nearby client terminal 10C may be applied. Alternatively, the performance part for the client terminal 10C may be dynamically changed during performance. For example, the client terminal 10C that was close to the beginning was in charge of the guitar, but when the client terminal 10C moves away, control such as changing to the base charge may be performed.

  In the above embodiment, the host terminal 10H extracts each piece of performance information PI from the ensemble information SI. Then, only the corresponding performance information PI is transferred to the client terminal 10C to which each performance part is assigned. As another method, the host terminal 10H may transfer the ensemble information SI to each client terminal 10C as it is. The assigned ID number is also transferred to each client terminal 10C. Then, in each client terminal 10C, necessary performance information PI may be acquired from the ID number assigned to the own device.

  In the above embodiment, the case where the musical instrument sound is output from the speaker 102 when the timing of the performance operation by the user coincides with the performance timing based on the performance information PI has been described. In addition to this, the following processing may be performed.

  The first method is a method of reproducing musical instrument sounds regardless of the timing of the performance operation of the user. However, when the timing is bad, that is, when the operation timing and the performance information PI are collated and the degree of coincidence is low, a low score is given. With this method, even if the user's performance is poor, as long as the performance operation is performed at any timing, the musical instrument sound is reproduced based on the performance information PI. Therefore, even a beginner can obtain a sense of performing professionally. However, since the score is displayed by matching the timing, you can compete for performance technique.

  The second method is a method in which the timing of the performance operation by the user is collated with the performance information PI, and if the degree of coincidence is low, the reproduced sound is reduced or extremely increased. According to this method, the user can confirm the performance of performance based on the volume of the reproduced sound.

  The third method is a method in which the timing of the performance operation by the user is collated with the performance information PI, and if the degree of coincidence is low, an incorrect reproduction sound is reproduced. For example, if you are playing a guitar part, but you perform a performance that is out of timing, you will hear the sound of a bell. According to this method, the user can confirm the performance of the performance from the reproduced sound. In addition, the performance failure itself can be enjoyed by arranging various performance failure sounds.

  As another method, the reproduced sound may be reproduced in accordance with the timing of the performance operation by the user. That is, even if the performance information PI and the timing of the performance operation are shifted, the reproduced sound is reproduced at the timing of the performance operation. At this time, the sound to be reproduced may be processed, for example, to reproduce the closest sound on the time axis of the performance information PI. Even in this case, the score display may be performed according to the timing of the performance operation of the user and the degree of coincidence of the performance information PI.
