[System power saving function]
In the electronic musical instrument system according to one embodiment of the present invention, power saving in the standby state during non-performance is achieved for both the performance operating device PM and the electronic musical instrument main body EM connected by the wireless WL, and the performance operating device PM. When a performance operation such as key-on is detected in the standby state, the power saving mode is entered into the normal operation mode (also referred to as “normal mode”), and the electronic musical instrument main body EM detects the radio signal from the performance operation device PM. Enter normal operation mode from mode. 2 is a functional block diagram of an electronic musical instrument system according to an embodiment of the present invention. FIG. 2 (1) is a functional block diagram of the electronic musical instrument main body, and FIG. 2 (2) is a functional block diagram of a performance operating device. It is.

  Here, the characteristics of the electronic musical instrument system according to an embodiment of the present invention will be briefly described with reference to FIG. 2. In this system, the performance controller PM and the electronic musical instrument main body EM are connected by wireless WL, Both operate in the power saving mode in the standby state. In the standby state (Sap2), the performance controller PM scans the performance operation of the performance operation unit PD with a low clock. When the performance operation unit PM detects a sleep cancel signal Sbp based on the start of the performance operation, the performance operation unit PM cancels the standby state and enters the normal mode. Operates, scans at a high clock, turns on the power supply 33 of the wireless communication unit 27, and transmits performance information Sd1 based on the performance operation to the electronic musical instrument main body EM by wireless WL. In the standby state (Sae2), the electronic musical instrument main body EM performs a reception check of the wireless communication unit 9 at a low frequency. When the wireless instrument EM detects a wireless signal from the performance operating device PM, the electronic musical instrument main body EM cancels the standby state and operates in the normal mode. The check is performed at a high frequency, and a tone signal based on the performance information Sd3 received by turning on the power supply 15 of the tone generator unit TG is generated in the tone generator unit TG.

  This will be described in more detail below. As shown in FIG. 2A, the electronic musical instrument main body EM functionally includes a main body microcomputer unit MCe that functions as a control unit for the electronic musical instrument main body EM by the main body CPU1, the main body RAM2, the main body ROM3, and the like, and a main body wireless communication. A musical sound for generating a musical sound signal based on the received performance information by the main body wireless communication unit 9, the tone generator circuit 7 and the effect circuit 8 functioning as wireless communication means for receiving performance information from the performance controller PM in one direction by the circuit 9. A sound source unit TG functioning as a signal generation unit, a main body setting unit including a main body detection circuit 5 and a main body setting operator 12, a main body display unit including a main body display circuit 6, a main body display 13, and the like, a sound system 14, an external storage device 4 and the like Thus, other main body parts RBe functioning as auxiliary or external means accompanying the performance information processing, and the power supply circuit 15 Composed of the main power supply unit 15 which functions as a power supply means for supplying more selectively power to each functional unit.

  Further, as shown in FIG. 2 (2), the performance operating unit PM is functionally an operating unit microcomputer unit that functions as a control means for the performance operating unit PM by the operating unit CPU 21, the operating unit RAM 22, the operating unit ROM 23, and the like. MCp, performance controller 30 and operation detector 24 detect a user's performance operation and a performance operation unit PD which functions as an operation detection means for fetching performance information based on the performance operation. From the operation unit wireless communication unit 27 functioning as a wireless communication means for transmitting to the main body EM in one direction, the setting operation unit including the setting detection circuit 25 and the operation unit setting operation element 31, the operation unit display circuit 26, the operation unit display 32, etc. Each of the other operation units RBp functioning as a performance operation assisting unit by the operation unit display unit and the battery circuit 33 Configured in Noh portion from selectively operating device power supply section 33 which functions as a power supply means for supplying electric power.

  The performance controller PM includes, for example, a keyboard-type performance operator 30 in the performance operation unit PD, and is driven by a battery of the operation unit power supply unit 33. The power supply unit 33 constantly supplies power to the operation unit microcomputer unit MCp and the performance operation unit PD, as indicated by a vertical solid line.

  In the standby state in which the performance operator 30 is not operated, the operating unit power supply unit 33 performs other functions as indicated by the vertical broken line in accordance with the operating unit power saving mode signal Sap1 from the operating unit microcomputer unit MCp. No power is supplied to the unit 27 and RBp. In the standby state, the performance operation unit PD also operates in the power saving mode in accordance with the controller power saving mode signal Sap2 from the microcomputer unit MCp. For example, the key scan clock is set to a lower speed or the scan frequency is lower than in the normal mode. The operating density is lowered to such an extent that the operation of the performance operator 30 can be detected, for example, and the microcomputer unit MCp itself enters a sleep state after transmitting each power saving mode signal.

  When the performance operation unit PD detects an operation of the performance operator 30 in the standby state, the performance operation unit PD generates an operation unit sleep cancel signal Sbp corresponding to the detected first operation, and supplies this to the operation unit microcomputer unit MCp. . In response to this, the microcomputer unit MCp cancels the sleep state, shifts to the operation state, and transmits a signal for invalidating the power saving mode signals Sap1 and Sap2 to the power supply unit 33 and the performance operation unit PD. As a result, the performance operation unit PD operates in the normal mode, performs high-clock key scanning, and the like, and can effectively capture the performance information Sd1 based on the performance operation of the performance operator 30. In addition, the power supply unit 33 starts power supply to other functional units, that is, the operation device wireless communication unit 27 and other operation device units RBp.

  The controller microcomputer unit MCp also generates a start instruction signal Ss1 in response to the reception of the sleep release signal Sbp, converts the performance information Sd1 received from the performance operation unit PD into performance information Sd2 of a predetermined format, and starts up. The instruction signal Ss1 and the performance information Sd2 are output to the controller wireless communication unit 27. Correspondingly, the wireless communication unit 27 converts the start instruction signal Ss1 and the performance information Sd2 into wireless communication signals Ss2 and Sd3 and unilaterally transmits them to the electronic musical instrument main body EM by wireless WL. While the performance operation is being performed, the signal transmission of the performance information Sd3 is continued. Note that the wireless communication unit 27 is for unidirectional communication, and can reduce power consumption and lengthen the battery of the power supply unit 33 as compared to bidirectional communication.

  When the performance operation of the performance operator 30 is stopped for a certain period of time or more, for example, about 5 to 10 minutes or more, the controller microcomputer unit MCp determines that the performance operation has been completed, and determines that the power supply unit 33 and The performance operation unit PD is sent to the power saving mode signals Sap1 and Sap2 to enter the power saving mode, and enters the sleep state and returns the entire performance operation unit PD to the standby state.

  In the performance operation unit PD, the setting operation units 25 and 31 and the operation unit display units 26 and 32 are not necessarily essential function units, and may be omitted as appropriate. If omitted, a remote control device for performing the setting operation may be prepared separately. In that case, the electronic musical instrument main body EM is provided with a receiving unit for receiving a signal from the remote control device.

  On the other hand, the electronic musical instrument main body EM includes a main body wireless communication unit 9 and a sound source unit TG for receiving performance information from the performance controller PM and generating a musical sound signal. It is driven by a power supply (using AC power). The power supply unit 15 always supplies power to the main body microcomputer unit MCe and the main body wireless communication unit 9 as indicated by a vertical solid line.

  In the standby state of the electronic musical instrument main body EM, the main body power supply unit 15 supplies power to the other functional units TG and RBe as indicated by the vertical broken lines in accordance with the main body power saving mode signal Sae1 from the main body microcomputer unit MCe. Do not supply. In the standby state, the main unit wireless communication unit 9 further operates in the power saving mode in accordance with the main unit power saving mode signal Sae2 from the microcomputer unit MCe, and performs a performance such as lowering the frequency of signal check compared to the normal mode. The operation density is lowered to such an extent that reception of a radio signal from the operation unit PD can be detected, and the microcomputer unit MCe itself enters a sleep state after transmitting each power saving mode signal.

  When the main body wireless communication unit 9 detects the reception of the activation instruction signal Ss2 from the performance controller PM by the wireless WL in the standby state, the main body wireless communication unit 9 generates the main body sleep release signal Sbe in response to the reception of the activation instruction signal Ss2. Is supplied to the main microcomputer unit MCe. In response to this, the microcomputer unit MCe cancels the sleep state, shifts to the operation state, and transmits a signal that invalidates the power saving mode signals Sae1 and Sae2 to the power supply unit 15 and the main body wireless communication unit 9. Thereby, the main body wireless communication unit 9 can effectively receive the performance information Sd3 by the wireless WL from the performance controller PM by a high-frequency signal check or the like. In addition, the power supply unit 15 starts to supply power to other functional units, that is, the sound source unit TG and other main body units RBe.

  The main body wireless communication unit 9 demodulates (decodes) the received performance information Sd3 into performance information Sd4 and sends the performance information Sd4 to the main body microcomputer portion MCe. The information is converted into information Sd5 and output to the sound source unit TG. The sound source unit TG generates a musical sound signal based on the performance information Sd5 from the microcomputer unit MCe, generates a corresponding musical sound in the sound system 14, and the main body wireless communication unit 9 receives the performance information Sd3 from the performance controller PM. During this time, the tone signal generation continues. When the wireless signal of the performance information Sd3 from the performance controller PM is interrupted for a certain time or more, the microcomputer unit MCe determines that the performance operation on the performance controller PM has been completed and waits for the electronic musical instrument main body EM to be in a standby state. Return to.

  With the above configuration, the power switch of the electronic musical instrument main body EM can be omitted, and power consumption in the performance operating device PM and the entire system can be suppressed.

(Battery circuit) 33 turns off the operating power of the operating unit wireless communication unit 27 and other operating unit units RBp, and the performance operation unit PD including the performance operation detection circuit 24 can detect the performance operation. A key scan is performed at a low clock. Here, when the performance operator 30 is operated by the user, the performance operation unit PD detects this operation, generates an operation unit sleep release signal Sbp, and sends it to the microcomputer unit MCp.

  On the other hand, first, in step P1, the operating unit microcomputer unit MCp receives the operating unit sleep cancel signal Sbp from the performance operating unit PD, cancels the sleep, and enters an operating state. Next, in step P2, a command to invalidate the controller power saving mode signal Sap2 is given to the performance operation unit PD, and the performance operation unit PD is operated in the normal mode to perform a performance operation scan at a high clock. . In the following step P3, a command to invalidate the power saving mode signal Sap1 to the operating device power supply unit 33 is performed, and the operating power of the operating device wireless communication unit 27 and other operating device units RBp is turned on to supply power to them. Supply. Furthermore, in step P4, an activation instruction signal Ss1 for the electronic musical instrument main body EM is generated and sent to the wireless communication unit 27. The wireless communication unit 27 converts the activation instruction signal Ss1 into an activation instruction signal Ss2 for wireless communication, and electronically It transmits to the musical instrument main body EM by wireless WL, and proceeds to the normal operation device processing at Step P5.

  The electronic musical instrument main body EM also operates in the power saving mode in the standby state, and according to the main body power saving mode signals Sae1 and Sae2 transmitted from the main body microcomputer unit MCe at the beginning of the transition to the standby state, the power supply unit (power supply circuit) 15 is that the power source of the sound source unit TG and the other main unit parts RBe is turned off, and the main body radio communication unit 9 performs reception check at a low frequency so that a radio signal from the performance controller PM can be detected. Yes. Here, when the wireless communication unit 9 receives the activation instruction signal Ss2 transmitted from the performance controller PM by wireless WL, the wireless communication unit 9 generates the main body sleep release signal Sbe in response to detecting this reception, and the microcomputer unit Send to MCe.

  On the other hand, the main body microcomputer unit MCe first releases the sleep in step E1 upon receiving the main body sleep cancel signal Sbe from the main body wireless communication unit 9 indicating that the start instruction signal Ss2 has been received from the performance controller PM. Then enter the operating state. Next, in step E2, a command for invalidating the main body power saving mode signal Sae2 is issued to the wireless communication unit 9, and the wireless communication unit 9 is operated in the normal mode to perform reception check with high frequency. Furthermore, in step E3, a command to invalidate the power saving mode signal Sae1 is given to the main body power supply unit 15, the operation power supply of the sound source unit TG and other main body units RBe is turned on, and power is supplied to them. The process proceeds to E4 main body normal processing.

  In the performance controller PM, the performance operation unit PD is set so as to operate in the normal mode in step P2. Therefore, a performance based on a user's performance operation that is continuously performed after the operation on the performance operator 30 is detected. The information Sd1 can be reliably captured. In the normal process of step P5, the controller microcomputer unit MCp receives the performance information Sd1 sequentially taken in by the performance operation unit PD, converts it into performance information Sd2 of a predetermined format, and sends it to the controller wireless communication unit 27. The wireless communication unit 27 further converts the performance information Sd2 into a performance information signal Sd3 for wireless communication and transmits the performance information signal Sd2 to the main body wireless communication unit 9 of the electronic musical instrument main body EM.

  In the next step P6, the controller microcomputer unit MCp checks the reception interval of the performance information Sd1 from the performance operation unit PD, and performs a performance operation by the performance operation unit PD for a certain period (for example, 5 to 10 minutes). It is determined whether or not 30 operations have been detected. While the performance operations are sequentially detected within a certain period of time and it is determined that the performance operations have continued (P6 → NO), the normal processing of step P5 is performed. continue. During the normal processing, the user can set the tone and volume by operating the operation unit setting operation element 31, and the setting data (operation unit setting data) based on this operation is stored in the microcomputer unit MCp and the operation unit. It is transmitted to the electronic musical instrument main body EM via the device radio communication unit 27.

  In the electronic musical instrument main body EM, the main body wireless communication unit 9 is set so as to operate in the normal mode in step E2, so that it is continuously transmitted from the performance operating device PM even after reception of the activation instruction signal Ss2 is detected. The incoming performance information signal Sd3 can be reliably received, demodulated (decoded) into performance information Sd4 in a predetermined format, and output to the main body microcomputer unit MCe. In the main body normal processing in step E4, the main body microcomputer unit MCe converts the performance information Sd4 from the wireless communication unit 9 into performance information Sd5 in a format suitable for the sound source unit TG, and outputs the performance information Sd5 to the sound source unit TG. Generates a musical tone signal based on the performance information Sd5, and further generates a corresponding musical tone by the sound system.

  In the next step E5, the main body microcomputer unit MCe checks the reception interval of the performance information signal Sd3 transmitted by the wireless WL from the performance controller PM, and performs a wireless signal for a certain period (for example, 5 to 10 minutes). It is determined whether or not Sd3 has been detected, and while the wireless signal Sd3 is sequentially received within a certain period and it is determined that the performance operation with the performance controller PM is continuing (E5 → NO), step The main body normal processing of E4 is continued. During normal processing, when the microcomputer unit MCe receives the operation unit setting data from the performance operation unit PM via the main body wireless communication unit 9, the microcomputer unit MCe causes the sound source unit TG to perform tone, volume, etc. based on the operation unit setting information. Can be set. Further, the user can operate the main body setting operator 12, and more detailed settings can be made by using the main body setting data based on this operation as compared with the operating device setting data from the performance operating device PM.

  Now, in the performance controller PM, when it is determined that the performance operation has not been detected for a certain period of time (P6 → YES), the controller microcomputer unit MCp sequentially proceeds to steps P7 to P9 and enters a standby state. Perform the migration process. First, in step P7, the power saving mode signal Sap1 is sent to the operating device power supply unit 33, the operating power of the operating device wireless communication unit 27 and other operating device parts RBp is turned off, and the power supply to these is cut off. In step P8, a power saving mode signal Sap2 is sent to the performance operation unit RD to set the performance operation unit PD to the power saving mode. Further, in step P9, the microcomputer unit MCp itself sleeps to return to the original standby state. Return.

  Correspondingly, in the electronic musical instrument main body EM, when it is determined that the performance operation in the performance operating device PM is completed without detecting a radio signal for a certain period (E5 → YES), the main body microcomputer unit MCe sequentially Proceeding to steps E6 to E8, similarly, a transition process to a standby state is performed. First, in step E6, the power saving mode signal Sae1 is sent to the main body power supply unit 15, the operation power supply of the sound source unit TG and other main body units RBe is turned off, and the power supply to these is cut off. A power saving mode signal Sae2 is sent to the wireless communication unit 9 to place the wireless communication unit 9 in the power saving mode. Further, in step E8, the microcomputer unit MCe itself sleeps and returns to the original standby state. It should be noted that the latest setting data input during the main body normal process in step E4 can be stored in the external storage device 4 and reflected in the next main body normal process.

[Various Embodiments]
The preferred embodiment of the present invention has been described above with reference to the drawings. However, this is merely an example, and the present invention can be variously modified without departing from the spirit of the invention. For example, the wireless communication between the performance controller and the main unit is unidirectional communication from the performance controller to the main unit in the embodiment, but may be bidirectional communication. In addition, when the unidirectional communication is adopted as in the embodiment, the transmission side (performance controller) cannot check whether the reception side (main device) has received correctly, so the state of the transmission side is periodically changed. It is desirable to send the information securely. For example, after sending a note-on message to the receiving side, the transmission side periodically notifies that the current state is the note-on state during the note-on.

  Various independent power sources, such as a dry cell, a storage battery, a solar cell, a fuel cell, and hybrids thereof, can be used for the battery of the performance operation unit.

  In the embodiment, it has been described that the power switch cannot be provided. However, the power switch is not completely removed. For example, the power switch is provided in a place where it is difficult for the user to operate, such as a performance controller or the back of the housing of the main unit. It may be provided. In this way, when not used for a long period of time, the power switch can be turned off to completely eliminate power consumption.
