  However, in the conventional performance apparatus, the user's work for automatic performance is as simple as operating the performance operator. Moreover, the automatic performance content by the operation of the performance operator is within the range that can be predicted by the user, and the performance content was not surprising.

  In order to solve the above problems, the user's work content required for the automatic performance operation is made more complicated and diverse, and the performance of the automatic performance by this work is surprising, and the automatic performance is more interesting. It is an object of the present invention to provide an automatic performance system, a communication terminal, a connector, and a block used in the automatic performance system.

  In order to solve the above problems, the present invention employs the following means.

  According to the configuration of the present invention described above, a solid is assembled by the user performing an assembly operation of a plurality of blocks. The three-dimensional body includes a communication terminal having a communication function, and the communication terminal acquires an assembly shape of the three-dimensional body and generates a sound generation instruction signal corresponding to the shape. A sound generation instruction signal is transmitted to the performance apparatus via the communication means by the communication terminal. A sound generation instruction signal is input to the performance device via communication. When the sound generation instruction signal is input, the performance device performs a performance at a pitch and a sound generation timing corresponding to the sound generation instruction signal.

  In this way, in the automatic performance system, automatic performance is performed at a pitch and a sounding timing according to how the user assembles the solid. In addition, since the automatic performance contents change depending on the assembly shape, it is difficult for the user to predict the performance contents due to the assembly work. In addition, it is difficult for the user to determine a three-dimensional assembly shape for performing an automatic performance with an arbitrary content. In this way, the user's work content required for the automatic performance operation can be made more complex and diverse, and the content of the automatic performance by this work can be surprising. As a result, it becomes possible to perform automatic performance with higher taste.

  (2) The present invention is the above-described automatic performance system, wherein the solid is formed by connecting the plurality of blocks via a connector, and the communication terminal has a sounding timing according to the position of the connector in the solid. A sound generation instruction signal is transmitted to the performance apparatus, and the performance apparatus performs at a sound generation timing indicated by the sound generation instruction signal.

  According to this configuration, the sound generation timing is changed according to the position of the connector in the solid. Accordingly, for automatic performance, the user is required to assemble a solid considering the position of the connector, and more diverse and complicated work is required. In addition, since the sound generation timing varies depending on the position of the connector, it is difficult for the user to predict the performance content of the assembly work. Also, it is difficult for the user to determine the position of the connector for performing an automatic performance with any content. As a result, it becomes possible to perform automatic performance with higher taste.

  According to the configuration of the present invention described above, the solid body includes a plurality of connectors having operation elements, and the plurality of blocks are combined through the connectors. A communication terminal is provided for each connector. In the communication terminal, when the operator is pressed, the control unit transmits a sound generation instruction signal to the performance device using the communication unit. At the same time, the control unit transmits a pronunciation token at a predetermined timing to communication terminals corresponding to other connectors connected to the same block. The performance device generates a sound when a sound generation instruction signal is input.

  And in the communication terminal corresponding to the connector connected to the same block as the connector, the pronunciation token is received by the communication unit. When the sound generation token is received, the control unit transmits a sound generation instruction signal to the performance device using the communication unit. At the same time, the control unit transmits a pronunciation token at a predetermined timing to communication terminals corresponding to other connectors connected to the same block.

  As described above, a sound is produced when the operator of one connector is pressed. A sound generation token is transmitted to the connector connected to the same block as the connector at a predetermined timing, and sound is generated when the sound generation token is input to the connector. This makes it possible for the user to perceive sound generation to be relayed between the connectors through the block, and sound generation can be performed according to the three-dimensional assembly shape with high taste.

When the performance apparatus receives the sound generation instruction signal, the connection angle It is characterized by sounding at a pitch corresponding to

  According to this configuration, when sound generation is relayed between the connectors as described in (3), the sound generation pitch corresponding to the connector changes according to the connection angle of the block to the connector. Accordingly, the user is required to assemble a solid in consideration of the connection angle of the block to the connector, and more diverse and complicated operations are required. In addition, since the sound generation timing varies depending on the position of the connector, it is difficult for the user to predict the performance content of the assembly work.

  Hereinafter, an automatic performance system according to the present invention will be described in detail with reference to the drawings.

<Outline of automatic performance system 100>
FIG. 1 is a perspective view of an automatic performance system 100 according to the present embodiment. The automatic performance system 100 includes a framework 200 (corresponding to the solid of the present invention) in which a plurality of stick-shaped blocks 210 are assembled, and a performance unit 300 that performs automatically with sound corresponding to the shape of the framework 200.

  The frame 200 is assembled by connecting a plurality of stick-shaped blocks 210 (hereinafter, sticks 210) to each other via a rectangular parallelepiped connector 220. Each connector 220 is connected to the performance system 100 so as to communicate with each other. The communicable configuration will be described later in detail.

  Further, the connector 220 is provided with a tact switch 221 (hereinafter referred to as a switch 221) on one end of the connector 220, and a connection portion 222 with the stick 210 is formed on the six surfaces thereof. Accordingly, a maximum of six sticks 210 can be connected to the connector 220.

  The connecting portion 222 can connect the stick 210 to each connecting surface from any direction, and can be approximately 0 ° to 180 ° by one or two sticks 210 connected to one connecting portion 222. The connection angle can be adjusted at a predetermined angle. The configuration of the connector 220 will be described later in detail with reference to FIG.

  Also, the lengths of the sticks 210 are not all the same, and there are various types of dimensions. As described above, the blocks can be combined via the connector 220 while selecting the length of the stick 210 to be used and the connection angle between the stick 210 and the connector 220. Accordingly, the user can assemble the frame 200 in any of various assembled shapes.

  Each stick 210 is formed to be transparent or translucent, and includes a light emitting unit group 211A in which a plurality of light emitting units 211 are arranged in a line along the longitudinal direction.

  The automatic performance system 100 executes a process of performing an automatic performance (automatic performance process) according to the assembled shape of the framework 200. In the automatic performance process, a process is executed to make the user perceive a sounding token (notification signal) to be relayed between the connectors 220 using the stick 210 as a runway. In FIG. 1, the pronunciation token is relayed as indicated by the solid arrow, and after the pronunciation token is input for all the connectors 220, the relay is performed as indicated by the dotted arrow.

  Hereinafter, the automatic performance process will be described schematically. In the automatic performance process, the connector 220 whose switch 221 is pressed outputs a sounding token to the other connector 220 via the stick 210. The connector 220 to which the sound generation token is input instructs the performance unit 300 to generate a sound (transmits a sound generation instruction signal). As a result, the performance unit 300 produces a sound. The connector 220 outputs a sounding token to the other connector 220 via the other stick 210. The connector 220 to which the sound generation token is input transmits a sound generation instruction signal to the performance unit 300. This allows the user to perceive the movement (relay) of the pronunciation token by hearing.

  Further, in order to make the user visually perceive the movement of the pronunciation token, the light emission point B is moved together with the pronunciation token in the automatic performance processing. Specifically, one light emitting unit 211 in the light emitting unit group 211A is sequentially blinked, so that the user can perceive the light emitting point B to move.

  When the user instructs the start of the relay by continuously pressing the switch 221 a plurality of times, the plurality of light emitting points B are output with a predetermined time difference. Further, when the user presses the switch of the connector 220 while the relay is being performed, the relay of the light emission point B is terminated at the connector 220.

  In addition, when the tact switch 221 is pressed, it is set in advance whether the light emitting point B is output to the stick 210 connected to any of the six connecting portions 222. It is also set in advance to which connection portion 222 the light emission point B is output when the light emission point B comes from the stick 210 of which connection portion 222. This setting will be described later in detail with reference to FIG.

  As described above, in the automatic performance system 100, the longer the length of the stick 210, the longer the sounding timing between the two connectors 220 connected to the stick 210.

  In the automatic performance system 100, the pitch of the connector 220 can be determined according to the opening angle between the stick 210 that inputs the light emission point B and the stick 210 that outputs the light. Moreover, you may raise / lower the predetermined pitch according to an opening angle.

  In some cases, like the connector 220 located in the middle of FIG. 1, the two sticks 210 serving as the runway of the light emitting point B are connected in a straight line (connection angle is 180 °). In the case of such a linear connection, no sound is generated when the light emitting point B arrives at the connector 220, and the sound generation token may be simply relayed.

  The opening angle between the two sticks 210 and the length of the stick 210 will be described later in detail with reference to FIGS.

  Accordingly, the user can change the sound generation timing depending on the selection of the length of the stick 210 connected to the connector 220. At the same time, the pitch can be changed by the user by selecting an opening angle for connecting the two sticks 210.

  For this reason, a user can compose music by performing a complicated and diverse work of assembling the framework 200 three-dimensionally. Further, the composition content (automatic performance) by this assembly is difficult for the user to predict, and the automatic performance can be performed with content that is surprising to the user. In addition, it is difficult for the user to determine the assembled shape of the framework 200 for composing with any performance content. As a result, it is possible to perform automatic performance with higher taste.

  In the automatic performance system 100, each stick 210 includes a communication line 212 and a power line 213 (see FIG. 5). Of these, one stick 210 (the farthest left in FIG. 1) is a connection stick 210A to which a communication and power supply cable 400 for connecting to the performance unit 300 is attached at the end. As described above, the connection stick 210 </ b> A is connected to the connector 220 at the end, and is also connected to the other stick 210 and the other connector 220 via the connector 220.

  As described above, a power network for supplying power to each connector 220 is formed. At the same time, a communication network M (described later with reference to FIG. 4) is formed between each connector 220 and the performance unit 300, and communication is performed between the performance unit 300 and each connector 220 via the communication network M. be able to.

  There may be a plurality of types of communication routes between each connector 220 and the performance unit 300, but in this embodiment, the shortest communication route between each connector 220 and the performance unit 300 is searched before the automatic performance. Then, a process for setting to perform communication using the searched shortest communication route is executed (communication route construction process). The communication route construction and communication route construction processing will be described later in detail.

  The performance unit 300 includes a relay device 310 and a performance device 320, and can perform communication between the performance device 320 and each connector 220 via the relay device 310 and the communication network M. . Specifically, the relay device 310 is provided with a connection terminal 311 for connecting the cable 400, and is thereby connected to the cable 400. At the same time, the relay device 310 is provided with a connection terminal 312 for connecting a communication cable 500 for communicating with the performance device 320. The communication cable 500 is connected to the relay device 310 by the connection terminal 312.

  The relay device 310 outputs a communication signal input via the cable 400 to the performance device via the communication cable 500. At the same time, the relay device 310 outputs a communication signal input from the performance device 320 via the communication cable 500 to the cable 400. In this way, the relay device 310 relays communication between each connector 220 and the performance device 320.

  The relay device 310 connects a power cable 600 having a power plug 600A at one end, and power is supplied from a power outlet via the power cable 600, and the power is supplied to the framework 200 (each connector via the cable 400). 220). Further, the relay device 310 includes an L channel and an R channel output terminal 312A to an audio device (not shown), and can thereby output an audio signal to the audio device.

  The performance device 320 includes a connection terminal 321 for connecting the cable 500 and a sound source 326 (see FIG. 5). The performance device 320 performs a performance based on the sound generation instruction signal when the sound generation instruction signal from the connector 220 input via the cable 500 is input in the automatic performance processing described above. Specifically, when the sound generation instruction signal is input, the performance device 320 performs a process of generating a sound with a pitch corresponding to the opening angle notified by the sound generation instruction signal. Thus, the performance device 320 can perform automatic performance based on the shape of the framework.

  The configuration of the performance unit 300 and the automatic performance processing on the slave unit side and the master unit side will be described later in detail with reference to FIGS. 5 and 9 to 11.

  The performance device 320 has a built-in speaker SP (see FIG. 5) and outputs a performance sound through the speaker SP.

  The performance device 320 includes an operation unit 322 on the upper surface. When the performance device 320 receives an operation for instructing a change in the volume setting from the user via the operation unit 322, the performance device 320 changes the volume setting according to the instruction. As a result, the volume of the automatic performance can be changed to an arbitrary one by the user.

  A power cable 700 having a power plug 700A attached to one end is connected to the performance device 320, and power is supplied from the power outlet to the performance device 320 via the power cable 700.

<Configuration of connector 220>
2A is a perspective view of the connector 220, and FIG. 2B is a view for explaining a method of connecting the connector 220 to both ends of the stick 210. FIG. As shown in FIG. 2A, the connector 220 has connection portions 222 formed on a total of six surfaces, that is, a top surface, a bottom surface, and a side surface of a substantially rectangular parallelepiped main body 220a. Each connecting portion 222 is a circular recess. As shown in FIG. 5B, the stick 210 can be connected to the connector 220 by inserting the end of the cylindrical stick 210 into the connecting portion 222.

  As described above, each connecting portion 222 can connect the stick 210 to the respective connecting surface from any direction, and the connection portion 222 can be simplified by one or two sticks 210 connected to one connecting portion 222. The connection angle can be adjusted by a predetermined angle of 0 ° to 180 °.

  A switch 221 is disposed in the vicinity of the corner on the upper surface of the connector 220. In addition, a communication terminal 1 to be described later with reference to FIG. The communication terminal 1 and each connection unit 222 are electrically connected, and the communication terminal 1 is electrically connected to the communication line 212 and the power line 213 (see FIG. 5) arranged on the stick 210 via each connection unit 222. It is connected to the.

<Determination of Connection Unit 222 for Outputting Pronunciation Token>
FIG. 3A is a diagram for explaining the correspondence relationship between the input connection unit 222 and the output connection unit 222 of the pronunciation token, and the correspondence relationship between the pressing of the switch 221 and the output connection unit 222 of the pronunciation token.

  In the figure, the surface side where the switch 221 is located is described as “up” and the surface side facing the surface is described as “down”. In addition, of the side surfaces, the left surface side in front of the figure is referred to as front, and the surface side facing the surface is referred to as rear. In addition, the right side in front of the figure is described as right, and the side facing the surface is described as left.

  In the present embodiment, as described above, when the switch 221 is pressed and when a sound generation token is input to the connection unit 222, the sound generation token is output to any one of the connection units 222.

  Here, the priority is given among the six connecting portions 222 in association with the condition of pressing the switch 221. In addition, a priority is given among the other five connection units 222 in association with the condition that the pronunciation token is input to the specific connection unit 222. The priority is given for each condition in which each of the six connection units 222 becomes a specific connection unit 222.

  And the connector 220 determines the connection part 222 with the highest priority among the connection parts 222 to which the stick 210 is connected for each condition according to the priority corresponding to each of the above conditions. When any one of the above-described conditions occurs, the connector 220 outputs a sounding token from the determined one connection unit 222.

  Hereinafter, an example of the connection unit 222 determined in accordance with the above conditions when the sticks 210 are connected to all the connection units 222 will be described.

  As indicated by the white arrow A1, when the switch 221 is pressed, the stick 210 connected to the connection portion 222 (first connection portion 222A) on the left side has the highest priority. For this reason, the first connection unit 222A is determined to be the connection unit 222 that outputs the pronunciation token. As indicated by the arrow A2, the first connection portion 222A has the highest priority even when a pronunciation token is input to the connection portion 222 (second connection portion 222B) on the upper surface side. For this reason, the first connection unit 222A is determined to be the connection unit 222 that outputs the pronunciation token.

  As indicated by an arrow A3, when a pronunciation token is input to the first connection unit 222A, the stick 210 connected to the front side connection unit 222 (third connection unit 222C) has the highest priority. For this reason, the third connection unit 222C is determined to be the connection unit 222 that outputs the pronunciation token. As indicated by the arrow A4, when a pronunciation token is input to the third connection unit 222C, the second connection unit 222B has the highest priority. For this reason, the second connection unit 222B is determined to be the connection unit 222 that outputs the pronunciation token.

  When a pronunciation token is input to the lower surface side connection portion 222 (fourth connection portion 222D), the right side surface connection portion 222 (fifth connection portion 222E) has the highest priority, as indicated by an arrow A5. High degree. For this reason, the fifth connection unit 222E is determined to be the connection unit 222 that outputs the pronunciation token. When a pronunciation token is input to the fifth connecting portion 222E, as indicated by an arrow A6, the connecting portion 222 (sixth connecting portion 222F) on the rear side has the highest priority. For this reason, the sixth connection unit 222F is determined to be the connection unit 222 that outputs the pronunciation token.

  When a pronunciation token is input to the sixth connection unit 222F, the fourth connection unit 222D has the highest priority as indicated by an arrow A7. For this reason, the fourth connection unit 222D is determined to be the connection unit 222 that outputs the pronunciation token.

<Connection between connection unit 222 and stick 210>
FIG. 3B shows the connector 220 in a state where the sticks 210 having different lengths are connected. The connection part 222 and the communication line 212 of the stick 210 are electrically connected. The stick 210 incorporates a register (not shown) that stores the stick length, and the communication terminal 1 (see FIG. 5) of the connection unit 222 obtains the stick length from the register via the communication line 212. .

  The communication terminal 1 controls the light emission of the light emitting unit group 211A of the stick 210 according to the acquired length of the stick 210.

  The connector 220 to which the pronunciation token is input outputs the pronunciation token to the connector 220 connected to the other end (of the own device) of the stick 210 at a timing according to the length of the stick 210. The connector 220, to which the sound generation token is input, transmits a sound generation instruction signal to the performance unit 300, whereby sounding is performed by the performance unit 300 at the timing.

  Further, as described above, the connection angle of the stick 210 to the connection portion 222 can be changed. A known angle sensor (not shown) is attached to each connecting portion 222, and the communication terminal 1 determines the connection angle (inclination angle and inclining direction) of the stick 210 based on a signal from the angle sensor (not shown). Can be detected. Using the detected connection angle, the communication terminal 1 calculates an opening angle between the stick 210 for inputting the pronunciation token and the stick 210 for outputting the pronunciation token.

  As described above, the pitch of the sound produced by the performance device 320 can be determined or changed according to the opening angle between the two sticks. The communication terminal 1 generates a sound generation instruction signal indicating the calculated opening angle and transmits the sound generation instruction signal to the performance device 320, thereby controlling the pitch of the sound of the performance device 320. Accordingly, the pitch can be changed by the user by changing the opening angle of the two sticks 210. In this embodiment, the pitch becomes higher as the opening angle is smaller. For example, the opening angle 45 ° shown in FIG. 6C has a higher pitch than the opening angle 90 ° shown in FIG.

<Construction of communication route>
FIG. 4 is a diagram illustrating an example of a communication route constructed by the automatic performance system 100. As described with reference to FIG. 1, each connector 220 and the performance unit 300 communicate with each other using the other connector 220 and the stick 210 as a communication path. For this reason, there may be a plurality of types of possibilities as communication routes between one connector 220 and the performance unit 300.

  For example, in FIG. 1, there are two communication routes of the connector 220 arranged on the leftmost side in FIG. 1, that is, a communication route indicated by a dotted arrow and a communication route indicated by a solid arrow in FIG. In the present embodiment, the automatic performance system 100 executes a communication route construction process described later before automatic performance, so that the shortest communication route between the performance unit 300 and each connector 220 (the number of connectors 220 that pass through the automatic performance system 100 is reduced). Search for fewer communication routes.

  In the automatic performance system 100, each connector 220 transmits a sound generation instruction signal to the performance unit 300 on the searched communication route. In the above example, since the dotted arrow is the shortest route than the solid arrow, the communication route of the connector 220 arranged on the leftmost side in the figure is constructed by the route indicated by the dotted arrow. FIG. 4B shows a communication route established between each connector 220 and the performance unit 300 in the framework 200 shown in FIGS. 1 and 4A.

  The constructed communication route is stored in each connector 220 (communication terminal 1 shown in FIG. 5). That is, each communication terminal 1 stores the connection unit 222 that should output a sound generation instruction signal based on the communication route as communication route information D1 (described later using FIG. 6A). When the sound generation instruction signal is input, each communication terminal 1 inputs the sound generation instruction signal to the connection unit 222 indicated by the communication route information D1. As a result, a sound generation instruction signal can be input to the stick 210 connected to the connection unit 222, and the sound generation instruction signal can be transferred to the connector 220 connected to the other end of the stick 210.

  As described above, by transmitting the sound generation instruction signal to the performance unit 300 between the connectors 220 in the communication route, each connector 220 transmits the sound generation instruction signal to the performance unit 300 through the established communication route. Can do.

  The communication terminal 1 is realized by, for example, a microcomputer or a housing of the connector 220. The communication terminal 1 includes a processing unit 2 realized by a CPU or the like, a storage unit 3 realized by a memory or the like, and a communication interface 4. The processing unit 2 executes the stored program so that the angle detection unit 21, the stick length detection unit 22, the operation processing unit 23, the timer 24, the communication control unit 25, the pronunciation token generation unit 26, and the pronunciation instruction signal generation unit 27 and the light emission control part 28 are provided.

  The storage unit 3 is realized by a memory such as a RAM or a ROM. The storage unit 3 functionally includes an own terminal ID storage unit 31, a communication route storage unit 32, a transmission timing storage unit 33, a light emission control information storage unit 34, an angle / stick length storage unit 35, and a transmission route storage unit 36.

  The own terminal ID storage unit 31 is an area for storing the terminal ID of the own device. The terminal ID is, for example, an IP address or the like, and is unique identification information given to each connector 220, relay device 310, and performance device 320.

The output connection unit ID is a connection unit ID of the connection unit 222 that outputs the pronunciation token. The opening angle information is an opening angle (up to 0 to 180 °) between the stick 210 connected to the connection part 222 indicated by the input connection part ID and the stick 210 connected to the connection part 222 indicated by the output connection part ID. It is information which shows.

This is an area for storing information (first priority information) indicating the priority among the six connection units 222 corresponding to the condition of pressing the switch 221. In addition, the transmission route storage unit 36 corresponds to the condition that the pronunciation token is input to the specific connection unit 222 as described with reference to FIG. This is an area for storing information (second priority information) indicating the priority at. The information indicates the priority for each condition in which the first to sixth connection units 222A to 222F become specific connection units 222, respectively.

As described above, the output connection unit table T5 includes the connection unit ID of the connection unit 222 determined using the first and second priority information as described above (the condition that a pronunciation token is input to the specific connection unit 222). , The condition that the switch 221 is pressed). For example, a condition that a pronunciation token is input to a specific connection unit 222 is indicated as an input connection unit ID, and a condition that the switch 221 is pressed is registered as an identifier indicating that the switch 221 is pressed.

  The communication interface 4 is electrically connected to the first to sixth connection parts 222A to 222F, and is thereby connected to the communication line 212 of the stick 210 via the connection part 222. As a result, the communication interface 4 can communicate with the other connector 220 and the performance unit 300 via the stick 210 and the other connector 220.

  When the stick 210 is electrically connected to the first to sixth connection parts 222A to 222F, the angle detection unit 21 receives information indicating the length of the stick 210 from a register built in the stick 210.

  The angle detection unit 21 determines that the stick 210 is connected to the connection unit 222 to which the information is input. The angle detection unit 21 deletes the registered content of the output connection unit table T5 at the start of power supply. The angle detection unit 21 outputs a pronunciation token in association with each condition (depression of the switch 221 and input of a pronunciation token to a specific connection unit 222) for the connection unit 222 to which the stick 210 is connected. To decide. This determination is performed using priority information stored in the transmission route storage unit 36. The angle detection unit 21 registers the determined connection unit ID of the connection unit 222 in the table T5 in association with each condition.

  Moreover, the angle detection part 21 deletes the registration content of the opening angle table T4 at the time of the supply start of electric power. The angle detector 21 is electrically connected to the angle sensors (not shown) of the first to sixth connecting parts 222A to 222F, and a signal indicating the connection angle of the stick 210 is input from the angle sensor (not shown). Is done.

  Using the signal, the angle detection unit 21 calculates the opening angle of the two sticks 210 indicated by the input connection unit ID and the output connection unit ID registered in association with the output connection unit table T5. The angle detection unit 21 registers opening angle information indicating the calculated opening angle in the opening angle table T4 in association with the input connection unit ID and the output connection unit ID.

  The angle detection unit 21 detects whether or not the register (not shown) of the stick 210 can be accessed at predetermined time intervals, and thereby determines whether or not the connection state of the stick 210 to each connection unit 222 is changed. When the angle detection unit 21 determines that the connection state of the stick 210 has been changed, the angle detection unit 21 updates the registered content of the output connection unit table T5 with the changed connection state. At the same time, the angle detection unit 21 generates the opening angle information of the portion related to the update, and updates the registration content of the opening angle table T4 with the generated opening angle information.

  The stick length detection unit 22 deletes the registered content of the stick length table T3 at the start of power supply. The stick length detection unit 22 is electrically connected to the stick 210 via each connection unit 222, and inputs information indicating the length of the stick 210 from a register built in the stick 210. As a result, the stick length detection unit 22 can acquire the length of the stick 210 connected to the connection unit 222.

  The stick length detection unit 22 registers the acquired length in the stick length table T3 in association with the connection unit ID of the connection unit 222 to which the stick 210 is connected.

  The operation processing unit 23 inputs an operation signal generated by pressing the switch 221 from the switch 221. The operation processing unit 23 notifies the communication control unit 25 of the input when an operation signal is input.

  The communication control unit 25 controls communication using the communication interface 4. Further, the communication control unit 25 generates the communication route information D1 and stores the communication route information D1 in the communication route storage unit 32 by executing a communication route construction process (child-side communication route construction process) described later with reference to FIG.

  Further, the communication control unit 25 executes a slave unit side automatic performance process to be described later. In the slave unit side automatic performance processing, the communication control unit 25 receives an operation signal from the switch 221 and a sound generation token from the communication interface 4. The communication control unit 25 causes the sound generation instruction signal generation unit 27 to generate a sound generation instruction signal when an operation signal or a sound generation token is input, and sends the sound generation instruction signal to the performance device 320 via the communication interface 4. Send. Here, the communication control unit 25 inputs a sound generation instruction signal to the connection unit 222 indicated by the communication route storage unit 32.

  Further, in the handset-side automatic performance processing, the communication control unit 25 searches the output connection unit table T5 on the condition that the connection unit ID (input connection unit ID) of the connection unit 222 to which the sound generation token is input or the switch 221 is pressed. . The communication control unit 25 can acquire the connection unit 222 that outputs the pronunciation token based on the output connection unit ID acquired thereby.

  The communication control unit 25 can acquire the length of the stick 210 connected to the connection unit 222 of the output connection unit ID by referring to the stick length table T3 with the acquired output connection unit ID.

  The communication control unit 25 searches the light emission timing table T2 stored in the light emission control information storage unit 34 with the acquired length. As a result, the communication control unit 25 can acquire the light emission timing of each light emitting unit 211 arranged on the connected stick 210. The communication control unit 25 instructs the light emission control unit 28 to cause each light emitting unit 211 to emit light at the light emission timing.

  The communication control unit 25 instructs the pronunciation token generation unit 26 to generate a pronunciation token. The communication control unit 25 searches the transmission timing table T1 with the length acquired from the stick length table T3. At the transmission timing acquired in this way, the communication control unit 25 inputs the generated pronunciation token to the connection unit 222 indicated by the output connection unit ID acquired from the output connection unit table T5.

  The sound generation token generation unit 26 generates a sound generation token and inputs the sound generation token to the communication control unit 25 when the communication control unit 25 receives a sound generation token generation instruction.

  The sound generation instruction signal generation unit 27 refers to the opening angle table T4 with the input connection unit ID and the output connection unit ID when an instruction to generate a sound generation instruction signal is received from the communication control unit 25. As a result, the sound generation instruction signal generation unit 27 acquires the opening angle information, generates a sound generation instruction signal including the information, and inputs the sound generation instruction signal to the communication control unit 25. The sound generation instruction signal is a signal described based on, for example, the MIDI (Musical Instruments Digital Interface) standard.

  The light emission control unit 28 is electrically connected to each connection unit 222, and is thereby electrically connected to the light emission unit 211 of the stick 210 connected to the connection unit 222 via the connection unit 222. The light emission control unit 28 controls light emission of the connected light emitting unit 211 in accordance with an instruction from the communication control unit 25.

  The performance unit 300 will be described below. The performance unit 300 includes the relay device 310 and the performance device 320 as described above.

  The relay device 310 is configured by connecting a first communication interface 313, a second communication interface 314, and a storage unit 315 to a control unit 316.

  The first communication interface 313 is connected to the cable 400 extending from the connection stick 210 </ b> A via the connection terminal 311. The first communication interface 313 inputs a sound generation instruction signal from the connector 220 input via the connection terminal 311 to the control unit 316. At the same time, the first communication interface 313 outputs a communication signal from the performance device 320 input from the control unit 316 to the connection terminal 311.

  Here, the cable 400 includes a power line in addition to the communication line. Electric power to be supplied to the connector 220 is output to the power line via the connection terminal 311.

  The second communication interface 314 is connected to the cable 500 connected to the performance device 320 via the connection terminal 312. The second communication interface 314 inputs a communication signal from the performance device 320 input via the connection terminal 312 to the control unit 316. At the same time, the second communication interface 314 outputs the sound generation instruction signal from the connector 220 input from the control unit 316 to the connection terminal 312.

  The storage unit 315 is implemented by, for example, a memory such as a RAM or a ROM, or a hard disk, and stores a predetermined program and also functions as a work area of the control unit 316.

  The performance device 320 includes the speaker SP and the operation unit 322, and includes a control unit 323, a storage unit 324, a communication interface 325, a sound source 326, an audio signal processing unit 327, and a D / A converter 328. The control unit 323, the operation unit 322, the storage unit 324, the communication interface 325, the sound source 326, the audio signal processing unit 327, and the D / A converter 328 are connected by a bus (not shown).

  The storage unit 324 is realized by a memory such as a RAM or a ROM, a hard disk, or the like, for example. The storage unit 324 functionally has a table storage area 324a that stores a pitch table T6 shown in FIG. The pitch table T6 is a table for registering the opening angle information and the pitch corresponding to the opening angle information in association with each other.

  The communication interface 325 is connected to the cable 500 via the connection terminal 321, and communicates with the relay device 310 via the cable 500. Here, the communication interface 325 inputs a sound generation instruction signal from the relay device 310 to the control unit 323 (a communication control unit 323A described later).

  The sound source 326 is a MIDI sound source, for example, and generates a digital audio signal with a predetermined tone color and pitch and inputs the digital audio signal to the D / A converter 328. The sound source 326 generates a sound with the pitch notified to the control unit 323 when a sound generation instruction is given from the control unit 323 (a performance control unit 323B described later).

  The audio signal processing unit 327 is realized by, for example, a DSP, and performs predetermined audio signal processing such as level adjustment and frequency adjustment on the audio signal generated by the sound source 326 and outputs the processed audio signal to the D / A converter 328. The audio signal processing of the audio signal processing unit 327 is controlled by the control unit 323 (a performance control unit 323B described later).

  The D / A converter 328 converts the digital audio signal input from the audio signal processing unit 327 into analog and inputs the analog audio signal to the speaker SP.

  The control unit 323 is realized by, for example, a CPU or the like, and functionally includes a communication control unit 323A and a performance control unit 323B by executing a program. The control unit 323 executes a master unit side automatic performance process to be described later using these function units. In the master-side automatic performance process, the communication control unit 323A controls communication of the communication interface 325. The communication control unit 323A outputs the sound generation instruction signal input from the communication interface 325 to the performance control unit 323B.

  In the master-side automatic performance process, the performance control unit 323B acquires opening angle information included in the sound generation instruction signal when the sound generation instruction signal is input. The performance controller 323B refers to the pitch table T6 with the opening angle information. Thereby, the performance control unit 323B acquires the pitch corresponding to the opening angle information, and instructs the sound source 326 to generate a sound with the acquired pitch.

  The performance control unit 323B receives an operation signal from the operation unit 322, and changes a control value for audio signal processing of the audio signal processing unit 327 based on the operation signal. For example, when an operation signal for instructing a volume change is input, the performance control unit 323B changes the level control value of the audio signal processing unit 327 according to the change instruction.

<Processing Performed by Automatic Performance System 100>
FIG. 7 is a flowchart showing a communication route construction process executed by the automatic performance system 100. The communication route construction process executed by the performance unit 300 is the parent-side route construction process. The communication route construction process executed by the connector 220 is a child side route construction process.

  First, in the parent side route construction process, when the user instructs the start of the route construction process using the operation unit 322, the performance unit 300 generates a message signal and outputs it to the connection stick 210A (S1). Specifically, an operation signal indicating an instruction to start execution of the communication route construction process is input from the operation unit 322 to the communication control unit 323A. When the operation signal is input, the communication control unit 323A reads the terminal ID of the own device from the storage unit 324, generates a message signal including the terminal ID, and outputs the message signal to the relay device 310 via the communication interface 325. To do. In the relay device 310, the control unit 316 inputs a message signal via the second communication interface 314. The control unit 316 reads the terminal ID of its own device from the storage unit 315 and includes the message ID in the message signal, and inputs the message signal to the connection stick 210A via the first communication interface 313. Thereafter, the parent-side route construction process is terminated.

  Through the above processing, a message signal is input to the connector 220 connected to the connection stick 210A.

  Next, the child side route construction process will be described. When the power supply is started, the connector 220 repeatedly determines at predetermined time intervals until the communication control unit 25 determines YES whether the message signal is input (S2). If it is determined that a message signal has been input (YES in S2), the communication control unit 25 determines whether or not the route construction time has been started (S3). If it is determined that the route construction time has not been started (NO in S3), the communication control unit 25 activates the timer 24 to start counting the route construction time (S4). Thereafter, the communication control unit 25 causes Step S5 described later to be executed.

  If it is determined that the route construction time has been started (YES in S3), the communication control unit 25 determines whether the communication route of the message signal is shorter than the communication route indicated by the communication route information D1. (S5). As shown in FIG. 8, the message ID includes the terminal ID of the connector 220 that has passed through the message signal by executing step S <b> 8 described later. Therefore, the communication control unit 25 can acquire the communication route of the message signal by referring to the terminal ID given to the message signal and the order of the terminal ID.

  When the first message signal is input, the communication route information D1 is not stored in the communication route storage unit 32. For this reason, the communication control unit 25 generates communication route information D1 using the communication route indicated by the input message signal, and stores it in the communication route storage unit 32. As shown in FIG. 6A, the communication route information D1 is generated by adding the connection unit ID of the connection unit 222 that has input the message signal to the terminal ID included in the message signal.

  From the second and subsequent message signal inputs, the communication control unit 25 compares the terminal ID including the communication route information with the number of terminal IDs included in the message signal, and determines that the smaller number is the shorter communication route. To do.

  If it is determined that the communication route indicated by the message signal is longer than the communication route indicated by the communication route information (NO in S5), the communication control unit 25 discards the message signal (S6), and will be described later. S9 is executed. On the other hand, if it is determined that the communication route of the message signal is shorter than the communication route indicated by the communication route information (YES in S5), the communication control unit 25 adds the terminal ID added to the message signal to the terminal ID. The communication route information D1 is generated by adding the connection portion ID of the connection portion 222 to which the message signal is input.

  Thereafter, the communication control unit 25 updates the communication route storage unit 32 with the generated communication route information D1 (S7). The communication control unit 25 reads the terminal ID from the own terminal ID storage unit 3 and includes it in the message signal. The communication control unit 25 outputs the message signal to all the connection units 222 to which the stick 210 is connected (S8). However, the communication control unit 25 does not output the message signal to the connection unit 222 that has been input in step S2.

  Thereafter, the communication control unit 25 refers to the timer 24 to determine whether or not the route construction time has elapsed (S9). If it is determined that the route construction time has not elapsed (NO in S9), the communication control unit 25 returns the process to step S2. On the other hand, if it is determined that the route construction time has elapsed (YES in S9), the communication control unit 25 stops the timer 24 and terminates this process.

  As described above, after the frame 200 is formed and the performance unit 300 and the frame 200 are connected via the cable 400, the communication route construction process is executed, so that the connection between each connector 220 and the performance device 320 is performed. The shortest communication route can be constructed.

  Next, the automatic performance process will be described with reference to FIGS. The automatic performance process executed by the connector 220 is the child performance process. Further, the automatic performance process executed by the performance unit 300 is the parent performance process.

  FIG. 9 and FIG. 10A are flowcharts (part 1 and part 2) showing the first child-side performance process. First, the communication control unit 25 determines whether an input of an operation signal by pressing the switch 221 is notified from the operation processing unit 23 and whether a pronunciation token is input from the communication interface 4 until it is determined that any signal is input. The determination is repeatedly made at predetermined time intervals (S11).

  If it is determined that one of the operation signal and the sound generation token has been input (YES in S11), the communication control unit 25 activates the timer 24 (S12). The communication control unit 25 acquires the connection unit 222 that outputs the pronunciation token as described above using the output connection unit table T5 stored in the transmission route storage unit 36 (S13).

  Thereafter, the communication control unit 25 refers to the length table T3 of the angle / stick length storage unit 35 and acquires the length of the stick 210 connected to the connection unit 222 determined in step S13. At the same time, the communication control unit 25 refers to the opening angle table T4 and uses the connection unit ID of the connection unit 222 determined in step S13 and the connection unit ID of the connection unit 222 to which the pronunciation token is input. The opening angle of the two sticks 210 connected to the connection unit 222 is acquired (S14).

  The communication control unit 25 determines whether or not the acquired opening angle is 180 ° (S15). If the acquired opening angle is not 180 ° (NO in S15), the communication control unit 25 notifies the sound generation instruction signal generation unit 27 of the opening angle and generates a sound generation instruction signal (S16).

  The sound generation instruction signal generation unit 27 generates a sound generation instruction signal (note-on data) including information indicating the notified opening angle and information indicating an operation signal or the number of times of input of the sound generation token, and the performance device 320 Are included in the communication control unit 25 as the destination terminal ID.

  When the sound generation instruction signal is input, the communication control unit 25 refers to the communication route storage unit 32 and acquires the connection unit 222 indicated by the communication route information (S17). The communication control unit 25 outputs a sound generation instruction signal to the acquired connection unit 222 (S18). Here, when there are a plurality of operation signals or sounding tokens input times (the number of times the switch 221 is pressed) input within a predetermined time, the communication control unit 25 performs the sounding instruction several times at predetermined time intervals. The signal is output to the connection unit 222. Thereafter, the communication control unit 25 executes Step S19 described later.

  When the acquired opening angle is 180 ° (NO in S15), the communication control unit 25 refers to the light emission timing table T2 with the length of the stick 210 acquired in step S14, and each light emitting unit of the stick 210. The light emission timing 211 is acquired.

  The communication control unit 25 notifies the light emission control unit 28 of the obtained light emission timing and the operation signal within the predetermined time period or the number of times of the pronunciation token input, and instructs the light emission start (S19). When the instruction is given, the light emission control unit 28 causes each light emitting unit 211 of the stick 210 connected to the connection unit 222 acquired in step S13 to emit light at the notified light emission timing. Here, the light emission control unit 28 outputs the light emission point B as many times as the number of input of the notified operation signal or pronunciation token.

  The communication control unit 25 causes the pronunciation token generation unit 26 to generate a pronunciation token, and acquires the output timing of the pronunciation token from the length of the stick 210 acquired in step S14 (S20). Specifically, the pronunciation token generation unit 26 searches the transmission timing table T1 by the length of the stick 210, and acquires the output timing of the pronunciation token (the time length of the timer 24).

The pronunciation token generator 26 repeatedly determines at predetermined time intervals until it determines YES whether the time length indicated by the timer 24 has reached the time length acquired in step S20 (S21). If it is determined that the measured time length indicated by the timer 24 has reached the time length acquired in step S20 (YES in S21), the pronunciation token generating unit 26 stops the timer 24 and transmits the pronunciation token to the communication control unit. To 25. The communication control unit 25 outputs a pronunciation token to the connection unit 222 determined in step S13 via the communication interface 4 (S22). Here, when the operation signal or the sound generation token is input a plurality of times within a predetermined time in step S11, the communication control unit 25 outputs the sound generation token to the connection unit 222 at a predetermined time interval.
Thereafter, the communication control unit 25 returns the process to step S11.

  FIG. 10B is a flowchart showing the second child-side performance process. The second child side performance process is executed in a multitask with the first child side performance process. The communication control unit 25 repeatedly determines at predetermined time intervals until it is determined whether or not a sound generation instruction signal has been input (S31). When it is determined that the sound generation instruction signal has been input (YES in S31), the communication control unit 25 acquires the connection unit ID indicated by the communication route information D1 (S32). Thereafter, the communication control unit 25 outputs a sound generation instruction signal to the connection unit 222 corresponding to the acquired connection unit ID (S33).

  By the second child side performance process, the sound generation instruction signal can be relayed to the performance unit 300 by the connector 220 in the communication path to the sound generation instruction signal transmission source connector 220 and the performance unit 300.

  FIG. 11 is a flowchart showing the parent performance process. The master performance process is executed after the performance device 320 has transmitted the message signal. The communication control unit 323A repeatedly determines whether or not a sound generation instruction signal has been input until it is determined that it has been input (S41). If it is determined that a sound generation instruction signal has been input (YES in S41), the communication control unit 323A causes the performance control unit 323B to acquire a pitch corresponding to the sound generation instruction signal (S42). Specifically, the performance control unit 323B acquires a pitch corresponding to the opening angle by referring to the pitch table T6 with the opening angle information included in the sound generation instruction signal.

  The performance controller 323B instructs the sound source 326 to generate a sound with the acquired pitch (S43). Thereafter, the performance control unit 323B returns the process to step S41.

  As described above, in the performance system 100 according to the present embodiment, an automatic performance can be performed with pronunciation according to the assembled shape of the frame 200. That is, the sound generation timing changes depending on the position where the connector 220 is arranged. In addition, the pitch changes depending on the connection angle between the connector 220 and the stick 210 (the opening angle between the stick 210 to which the sound generation token is input and the stick 210 to which the sound generation token is output).

  For this reason, it is difficult for the user to determine the shape of the frame 200, that is, the performance content corresponding to the arrangement position of each connector 220 and the opening angle between each connector 220 and the stick 210. In addition, it is difficult for the user to easily determine the shape of the frame 200 for automatically playing an arbitrary performance content, that is, the arrangement position of each connector 220 and the opening angle between each connector 220 and the stick 210.

  From the above, it is possible to make the user's work content required for the automatic performance operation more complicated and diverse, and to give unexpectedness to the content of the automatic performance by this work. As a result, automatic performance can be performed with higher taste.

  In the present embodiment, the following modifications can be adopted.

  (1) In this embodiment, the connector 220 includes the communication terminal 1, but the communication terminal 1 may be connected to the outside of the connector 220. Further, the communication line 212 and the power line 213 may be outside the stick 210.

  (2) Further, the communication between the performance unit 300 and the connector 220 is not limited to the configuration performed via the communication network M. For example, in addition to the communication line 212, a communication line between the performance unit 300 and the connector 220 may be provided separately.

  (3) The automatic performance processing is not limited to the processing shown in FIGS. 9 to 11 as long as sound generation can be relayed between the connectors 220 in the framework 200.

  (4) In the present embodiment, all the sticks 210 have the same cross-sectional shape, but are not limited to this configuration. For example, a stick having various cross-sectional shapes may be prepared and a performance corresponding to the cross-sectional shape of the connected stick may be performed. For example, the tempo at which the pronunciation token passes through the stick and the tempo of the corresponding pronunciation between the connectors 220 connected to both ends of the stick may be changed.

  FIG. 12A is a diagram showing the shape of the connection portion 222 of the connector 220 ′ according to the modification, and FIG. 12B is a diagram showing the cross-sectional shape of the stick 210 (210a to 210d) according to the modification. It is.

  The stick 210a has a circular cross section. The stick 210b has a triangular cross section. The stick 210c has a square cross section. The stick 210d has a cross-shaped cross section. The connector 220 'includes connection portions 222 on six sides to which all of the sticks 210a to 210d having different cross-sectional shapes can be connected.

  The connecting portion 222 is provided with a plurality of tact switches (not shown), and these tact switches are different depending on the sticks 210a to 210d to be connected. Referring to FIG. 5, in this modification, the processing unit 2 includes a stick shape detection unit 29, and the stick shape detection unit 29 receives an on / off signal from a tact switch (not shown). The stick shape detection unit 29 acquires the shape of the connected stick 210 according to the on / off signal.

  The angle / stick length storage unit 35 stores a stick length / shape table T7 as shown in FIG. 13A instead of the stick length table T3. The stick length / shape table T7 is a table for registering the connection portion ID and the length and shape of the stick 210 connected to the connection portion 222 of the connection portion ID in association with each other. The stick shape detection unit 29 registers the acquired stick shape in the table T7 in association with the connection unit ID.

  The transmission timing storage unit 33 stores a transmission timing table T8 shown in FIG. 13B instead of the transmission timing table T1. The transmission timing table T8 is a table for registering the pronunciation token transmission timing corresponding to the stick length and the stick shape. Further, the light emission control information storage unit 34 stores a light emission timing table T9 shown in FIG. 13C instead of the light emission timing table T2. The light emission timing table T9 is a table for registering the light emission control timing corresponding to the stick length and the stick shape.

  In step S14 of the first child side performance process shown in FIG. 9, the communication control unit 25 refers to the stick length / shape table T7 by the connection unit ID, and acquires the length and shape of the stick 210.

  Further, in step S19 of the first child side performance process shown in FIG. 10, the communication control unit 25 searches the table of the light emission control information storage unit 34 by the acquired shape and length. Thereby, the light emission control timing according to the shape and length of the stick 210 can be acquired. In step S20 of the first child side performance process shown in FIG. 10, the communication control unit 25 searches the stick length / shape table T7 for the acquired shape and length instead of the stick length table T3. As a result, the sounding token transmission timing according to the shape and length of the stick 210 can be acquired.

  As described above, in the modification, the performance tempo and the moving speed of the pronunciation token can be changed according to the cross-sectional shape of the connected stick 210.

  (5) In the present embodiment, there are six connection portions 222 of the connector 220, but the present invention is not limited to this configuration. For example, the connector 220 may be provided with only five or less connection portions 222. Further, the same number of connection portions 222 may not be provided in all the connectors 220. For example, the frame 200 may be formed by a plurality of types of connectors 220 in which various numbers of connection portions 222 are arranged.

  (6) In this embodiment, one automatic performance system is provided with one sound source. However, a single automatic performance system may be provided with a plurality of sound sources. The stick 201 and the connector 220 may be provided.

  (7) In the present embodiment, the example in which the framework 200 and the relay device 310 are connected by wire is shown, but these may be connected wirelessly.

  (8) In the present embodiment, the relay device 310 and the performance device 320 are separated from each other, but they may be configured integrally.
