This power supply can be switched on and off by a specific input operation to an operation reception unit.

[0003] In addition, some electronic musical instruments output sound not only based on musical performance actions, but also based on audio data acquired from external devices. It is also possible to superimpose the audio output based on this audio data and the audio output according to musical performance actions. Patent Document 1 discloses a technology for optimizing the processing of a signal processing circuit related to audio output in an electronic musical instrument having a musical instrument performance function and a music playback function, depending on whether or not power is supplied to the musical instrument performance function.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an electronic keyboard instrument 1, which is an electronic musical instrument according to the present embodiment. The electronic keyboard instrument 1 includes a function operation reception section 11, a performance reception section 12, a display section 60 (announcement section), and the like.

[0011] The performance reception unit 12 is a part that receives operations for performing a performance on the electronic keyboard instrument 1, and includes a keyboard 121, a pitch bender 122 (pitch bend), and the like. The keyboard 121 is not particularly limited, but has an arrangement of white and black keys that accept operations to output each sound in a range of just over seven octaves. Unless otherwise specified, the keyboard 121 accepts operations to specify pitches to be output in equal temperament for each semitone. The keyboard 121 may include a pedal keyboard (foot keyboard) that is operated with the feet in addition to or instead of the keys that are normally operated with the fingers.

[0012] The pitch bender 122 has a roughly disk-like shape, with the normal direction of the disk surface positioned parallel to the arrangement direction of the keys 121 (the left-right direction in FIG. 1). The pitch bender 122 is a rotating wheel that is positioned so that a partial angular range of the roughly disk-like shape protrudes from the top surface of the electronic keyboard instrument 1, and can be rotated around the center of this disk within a certain movable angular range that is wider than the protruding angular range.

[0013] FIG. 2 is an enlarged perspective view of the pitch bender 122 and its vicinity. The pitch bender 122, by its rotation operation, continuously changes the pitch, which can only be output on the keyboard 121 in semitone units, according to the rotation angle (amount of rotation from a central rotation position (reference position) serving as a reference). The pitch bender 122 has, for example, a depression 122a for placing a finger on the reference position, which is not particularly limited. When the user releases his / her hand, the pitch bender 122 automatically returns to the reference position (amount of rotation is zero). The amount of change in pitch at the maximum rotation angle (amount of rotation) may be changeable (for example, within a range of a semitone to one octave) by a setting operation. The pitch bender 122 has a pitch bender light-emitting unit 31 (see FIG. 3) that emits light, located inside, and has a window L through which the light emitted by the pitch bender light-emitting unit 31 passes and exits. Here, the window L is located in a substantially arc shape along the outer periphery of the side surface of the pitch bender 122 (the edges of the upper and lower surfaces of the disk) (only one side is shown here). It should be noted that the window portion L only needs to be capable of transmitting light, and does not need to be transparent (visible) inside.

[0014] It should be noted that the electronic keyboard instrument 1 may have a modulation wheel instead of or alongside the pitch bender 122. The modulation wheel adjusts and defines the modulation of the sound, for example, the magnitude of vibrato, and can be rotated within a certain angle range from a central rotation position that serves as a reference, just like the pitch bender 122. On the other hand, the modulation wheel remains in that position even if the user releases it, and does not automatically return to the reference position (zero rotation amount).

[0015] The function operation reception unit 11 receives input operations such as whether or not power is supplied to the device itself (the electronic keyboard instrument 1), volume settings, settings of tone and reverberation during performance, etc. The function operation reception unit 11 has a power switch 111, a volume switching unit 112, a setting reception unit 113, etc.

[0016] The power switch 111 is a push button switch that accepts an operation to switch on and off the power supply to the device itself. A power switch light emitting unit 32 (see FIG. 3) is located inside the power switch 111 and emits light when the power supply is on. The light emitted by the power switch light emitting unit 32 is not particularly limited, but may be white.

[0017] The volume switching unit 112 is a rotary switch that adjusts the volume when sound is output from the speaker 72 (see FIG. 3). The volume switching unit 112 can rotate within a range indicated by a mark indicating the rotation direction, for example, within a range of about 300 degrees, and is switched so that the output volume increases as the mark position moves clockwise, for example. The volume switching unit 112 may be another operation switch, such as a combination of a push button switch for increasing the volume and a push button switch for decreasing the volume.

[0018] The setting reception unit 113 receives settings for tone (frequency spectrum (harmonic) distribution), effects such as reverberation, metronome sound that is output simultaneously for practice, pitch, etc. The setting reception unit 113 is a touch panel here, although not particularly limited thereto, and detects a touch operation of a finger or the like at a position overlapping with the display content of the display unit 60, and receives an input operation according to the touch position.

[0019] The display unit 60 displays the setting status and contents of various functions. For example, the state of the function settings is indicated by the presence or absence of a light source such as an LED (which may include blinking, its speed, pattern, etc.) below (inside) the light output window on which a sign or the like for identifying the content of the function settings is attached. As described above, the light output window may be positioned so as to overlap the touch panel in a plan view. The display unit 60 may have a digital display screen such as a liquid crystal display, and may be able to indicate the setting contents, for example, the sound quality setting of the output sound, by displaying characters, signs, etc. on the digital display screen.

[0020] The display unit 60 and the setting reception unit 113 include a touch encoder 61. The touch encoder 61 is a module that executes simple processing (including output of processing commands to other parts of the electronic keyboard instrument 1) in response to touch operations or external operations (signals input in response to external operations). The touch encoder 61 has a light-emitting unit such as an LED, and can illuminate the periphery of its upper surface.

[0021] FIG. 3 is a block diagram showing the functional configuration of the electronic keyboard instrument 1. As shown in FIG. The electronic keyboard instrument 1 includes an operation reception unit 10, a light emission unit 30, a CPU (Central Processing Unit) 40 (control unit), a memory unit 50, a display unit 60, an audio output circuit 71, a speaker 72, a communication unit 80, and the like.

[0022] The operation reception unit 10 receives an input operation and outputs a signal corresponding to the input operation. The operation reception unit 10 includes the performance reception unit 12 and the function operation reception unit 11 described above.

[0023] In addition to the above, the function operation receiving unit 11 may have any one of a dedicated push button switch, a rotary switch, a rocker switch, a slide switch, and the like, or a combination of a plurality of these.

[0024] The light-emitting unit 30 includes the pitch bender light-emitting unit 31 (first light-emitting unit) and the power switch light-emitting unit 32 (second light-emitting unit). The light sources are LEDs, and the power switch light-emitting unit 32 may be a monochromatic white LED. The power switch 111 has, for example, a cover member made of a circular light-transmitting member (the inside does not need to be visible), and light from the LED located below the cover member is emitted to the outside through the light-transmitting member, thereby lighting at least a part of the inside or periphery of the power switch 111 (the portion that detects the pressing operation).

[0025] The pitch bender light-emitting unit 31 has a set of LEDs of each of the R, G, and B colors, and is capable of emitting light in different colors. Light emitted by the LEDs inside the pitch bender 122 is guided to the vicinity of the outer periphery of the pitch bender 122 via a light-guiding member or the like as necessary, and is emitted to the outside through the light-transmitting window L while suppressing non-uniformity (almost evenly). The color of the emitted light can be appropriately switched and changed depending on the combination of luminance of each of the R, G, and B colors. Furthermore, the pitch bender light-emitting unit 31 may have multiple sets (e.g., three sets) of LEDs that emit light in multiple directions along the rotation direction of the pitch bender 122, and may be capable of emitting light of different colors in each rotation direction.

[0026] The CPU 40 is a processor that performs arithmetic processing and controls the overall operation of the electronic keyboard instrument 1. The CPU 40 may be a single processor or multiple processors that execute processes in parallel or independently depending on the processing. The CPU 40 is not limited to a general-purpose processor, and may include a processor that performs dedicated processing.

[0027] The storage unit 50 includes a volatile memory (RAM) and a non-volatile memory. The RAM provides a working memory space for the CPU 40 and stores temporary data. The non-volatile memory stores operation information, a control program 51, and the like. The operation information may include the contents of the operation for a preset setting, for example, processing of tone (harmonic distribution), sound onset, and reverberation (echo). The operation information also includes light emission color information 52 related to a change pattern of the light emission color of the pitch bender light-emitting unit 31, which will be described later. The program 51 includes a light emission control program for the pitch bender light-emitting unit 31 using the light emission color information 52 and the like. At least the CPU 40 and the storage unit 50 constitute the computer of this embodiment.

[0028] The display unit 60 performs display operations under the control of the CPU 40. As described above, the display unit 60 has a section that indicates function settings and the like by turning on / off the LED lamps, and a display screen.

[0029] The audio output circuit 71 generates a drive signal for outputting from the speaker 72 an output sound corresponding to the settings accepted by the operation of the performance accepting unit 12 and the setting accepting unit 113, and outputs the drive signal to the speaker 72. The speaker 72 generates and outputs a sound corresponding to the drive signal. The audio output circuit 71 and the speaker 72 may be stereo compatible.

[0030] The communication unit 80 controls communication with an external device. The communication unit 80 can receive audio data input from an external device and output the audio from the speaker 72 via the audio output circuit 71 in real time. The communication unit 80 may have a connection terminal for connecting a signal line, or may have a network card for connecting to a network. In addition to or instead of these, the communication unit 80 may have an antenna and a communication module for short-range wireless communication such as Bluetooth (registered trademark), and may be capable of transmitting and receiving data to and from an external device via short-range wireless communication.

[0031] Next, the power switch 111 of this embodiment will be described. The electronic keyboard instrument 1 can be switched between a stopped state in which the power supply is cut off (off) and operation is stopped, a normal operating state in which power is received (on) and normal operation is possible, and a standby state in which operation related to playing the instrument is stopped. In the normal operating state, all the functions of the electronic keyboard instrument 1 can be executed, such as outputting a performance sound from the speaker 72 in response to the operation of the keyboard 121. In the stopped state, it is sufficient that the electronic keyboard instrument 1 is in a state in which the ON operation of the power switch 111 can be detected, and for example, power is supplied only to the power switch 111 and the parts of the CPU 40 that are necessary for detecting the ON operation of the power switch 111, and power is not supplied to other parts. In the normal operating state, the light-emitting part of the touch encoder 61 displays a circle (annular shape) with a certain brightness on the periphery of its upper surface.

[0032] When the power switch 111 is pressed in the stopped state (this may require a continuous pressing operation for a specified time or longer), power supply is started, and the CPU 40 and each unit are started, and the device transitions to normal operation. In the normal operation state, if a reference time (several minutes, for example, six minutes) has passed without any operation related to performance, i.e., pressing any key on the keyboard 121 or rotating the pitch bender 122 (rotating wheel), the device automatically transitions to a standby state. Also, if any operation related to performance is detected in the standby state, the device immediately returns to the normal operation state.

[0033] In the standby state, the performance function is turned off. That is, in the electronic keyboard instrument 1, the processing circuits related to the output of sounds corresponding to the operations related to the performance are turned off, and various display operations by the display unit 60, the light emission operation of the power switch light emission unit 32, and the reception of setting operations to the setting reception unit 113 are stopped. On the other hand, in the electronic keyboard instrument 1, only the pitch bender light emission unit 31 is kept lit even in the standby state, indicating that the power supply is not cut off. In this state, when an audio signal is input via the communication unit 80, the speaker 72 can output audio based on the audio signal. That is, in the standby state, the electronic keyboard instrument 1 operates as an external speaker for other electronic devices.

[0034] Furthermore, when the power switch 111 is pressed in a normal operation state, whether the operation request is to cut off the power supply and transition to a stopped state or a transition to a standby state (an operation request with a different content) is determined depending on whether a continuous (successive) pressing operation (i.e., a long press) for a reference time (e.g., one second) or more is detected, and processing according to either request is performed. Furthermore, when the power switch 111 is pressed in a standby state, a simple display indicating that the device is in a standby state is displayed, and the standby state is maintained as is, but as in normal operation, if the power switch 111 is pressed for a reference time or more, it may be determined that an operation request to transition to a stopped state has been accepted.

[0035] That is, among the switching operations related to the power supply, the operation requesting a transition from a normal operating state to a stopped state or a standby state is used in combination based on the detection duration of a single operation, that is, pressing the power switch 111. Therefore, it is difficult for a user who operates the power switch 111 to stop the operation of the electronic keyboard instrument 1 to know how long he or she needs to keep pressing the switch before a request for an operation to switch to a stopped state is generated, and there is a possibility that a different operation request is generated by mistake.

[0036] In the electronic keyboard instrument 1, when pressing of the power switch 111 is detected during normal operation, the light-emitting portion of the touch encoder 61 displays a circle (annular shape) on the upper peripheral portion that is brighter than that during normal operation, and performs an alarm operation in which the display angle (length of the line) is shortened (the alarm stage is changed) at a speed at which the entire circle disappears in a reference time from the start of detection of the press while the detection continues (until it is no longer detected) or until a reference time has elapsed, thereby communicating an estimate of the remaining time until transition to a stopped state.

[0037] 4 and 5 are diagrams for explaining the change in the display state when the power switch 111 is operated. As shown in FIG. 4(a), in the normal operation state, the display unit 60 displays various setting states and settings change acceptance. When the power switch 111 is pressed, a circle C is displayed on the display surface of the touch encoder 61. When the detection duration of the pressed state of the power switch 111 becomes longer, as shown in FIG. 4(b), the circle C gradually becomes shorter, and here, it is erased in order clockwise from the 12 o'clock direction, and all the circles C disappear after one revolution in the reference time. Note that the display of the circle C does not need to strictly indicate the ratio of the remaining time to the reference time, and it is sufficient that the touch encoder 61 can display (notify) the degree of the detection duration in multiple stages. In addition, for example, the tip of the circle C (the end on the side where the display is erased) may be displayed with a visual effect such as fading out at a certain time.

[0038] When the detection duration of the pressed state reaches a reference time, all the circles C disappear, and an operation request for cutting off the power supply (transition to a stopped state) is accepted, and processing for transitioning to a stopped state (operation stop processing, first processing) is started. Here, as shown in Fig. 5, "bye" is displayed on the display screen of the display unit 60 for a certain period of time (e.g., 1-2 seconds), all displays (except for the lighting of the pitch bender light emitting unit 31 as described above) are terminated (erased), the temporarily stored data in the RAM of the storage unit 50 is erased (there is no need to actively perform an erasing operation, it is sufficient to stop the refresh operation), and the CPU 40 is turned off.

[0039] If the user or the like stops (ends) the pressing operation of the power switch 111 from the outside before the circle C disappears after a reference time has elapsed since the start of the pressing operation, the process of transitioning to the stopped state (operation stop process) is not performed. In this case, another process, for example, a process of transitioning to a standby state (second process) is performed. When the process of transitioning to the standby state is performed, for example, "standby: OK" may be temporarily displayed on the display unit 60 instead of the above-mentioned "bye". Alternatively, in this case, the display content of the touch encoder 61 may not be changed (erased) immediately, and the display of the part of the circle C that was partially erased may be maintained for a certain period of time (for example, 1-2 seconds).

[0040] When the pitch bender 122 is not in a stopped state, the pitch bender 122 emits light in a desired color from the window L along the outer periphery of the upper and lower surfaces (side surfaces) of the substantially disk shape as described above by emitting light from the pitch bender light emitting unit 31. When the pitch bender 122 is rotated, the color of the light emitted from the window L changes according to the direction and amount of rotation. For example, when the pitch bender 122 is rotated toward the treble side, the emitted color may be shifted to red, and when the pitch bender 122 is rotated toward the bass side, the emitted color may be shifted to green.

[0041] When the pitch bender 122 is not being rotated, the pitch bender light-emitting unit 31 changes its emission color (the color of the light emitted from the window L) slowly over time. Here, the change over time may be periodic or random.

[0042] FIG. 6 is a diagram showing an example of changes in light emission intensity of the LEDs of each color, R, G, and B, in the pitch bender light-emitting section 31. In FIG. For example, the emission intensity (brightness) of each color of RGB changes in a 6-second cycle. Note that here, the periodic change is determined mainly within the range of red and green so as not to change to blue emission for other purposes (not explained), but the emission change pattern need not be like this.

[0043] 7 is a flowchart showing a control procedure by the CPU 40 of an operation stop control process, which is an operation status notifying method of the present embodiment executed by the electronic keyboard instrument 1 of the present embodiment. This operation stop control process is started when a pressing operation of the power switch 111 is detected in a normal operation state.

[0044] The CPU 40 starts counting the duration of detection of the pressed state of the power switch 111 (step S201). The CPU 40 causes the touch encoder 61 to light up the entire circle C (step S202).

[0045] The CPU 40 determines whether or not the detection of the pressing operation of the power switch 111 continues (step S203). If it is determined that the detection of the pressing operation continues ("YES" in step S203), the CPU 40 determines whether or not the counted detection duration time has become equal to or longer than a reference time (the reference time has elapsed) (step S204).

[0046] If it is determined that the detection duration is not equal to or longer than the reference time ("NO" in step S204), the CPU 40 changes and controls the lighting range of the touch encoder 61 in accordance with the detection duration (step S212; notification control means). Then, the processing of the CPU 40 returns to step S203. If it is determined that the detection duration is equal to or longer than the reference time ("YES" in step S204), the CPU 40 performs an operation stop processing of the electronic keyboard instrument 1 (step S205; first execution means). As described above, the CPU 40 ends the processing related to the sound output (associated with the performance and external sound data), ends the display operation, ends the normal operation of the CPU 40 itself, and ends the operation of the electronic keyboard instrument 1. Then, the CPU 40 ends the operation stop control processing. As a result, the electronic keyboard instrument 1 transitions from the normal operation state to the stop state.

[0047] If it is determined in the determination process of step S203 that the detection of the pressing operation is not continuing (here, a state in which a pressing operation has not been detected for a reference time or longer) ("NO" in step S203), the CPU 40 performs processing to transition to a standby state (step S211; second execution means). The CPU 40 ends the processing for outputting sound related to the performance, and also ends display operations other than the light emission control of the pitch bender light emitting section 31. Then, the CPU 40 ends the operation stop control processing.

[0048] 8 is a flowchart showing a control procedure by the CPU 40 of the light emission control process of the pitch bender light emitting section 31 executed in the electronic keyboard instrument 1. This light emission control process is automatically started when the supply of power to the electronic keyboard instrument 1 is started, and is continuously and repeatedly performed while the supply of power to the electronic keyboard instrument 1 continues.

[0049] The CPU 40 turns on each LED of the pitch bender light emitting section 31 so as to emit light in the initial color (step S101). The CPU 40 obtains information on the amount of rotation of the pitch bender 122 (step S102).

[0050] The CPU 40 determines whether the amount of rotation of the pitch bender 122 has changed since the previous information acquisition (step S103). If it is determined that the amount of rotation of the pitch bender 122 has changed ("YES" in step S103), the CPU 40 refers to the light emission color information 52 and acquires the brightness setting value of each LED according to the amount of rotation of the pitch bender 122 (step S111).

[0051] The CPU 40 sets a luminance change pattern for continuously changing the luminance from the current luminance value to the luminance setting value based on the difference between the current luminance value and the acquired luminance setting value (step S112). The CPU 40 acquires the next luminance value and the timing of changing to the luminance value according to the set luminance change pattern (step S113).

[0052] The CPU 40 changes the luminance of each LED of the pitch bender light emitting section 31 at the change timing (step S107). Then, the process of the CPU 40 returns to step S102.

[0053] If it is determined in the determination process of step S103 that there is no change in the amount of rotation of the pitch bender 122 ("NO" in step S103), the CPU 40 determines whether or not the amount of rotation of the pitch bender 122 is zero (step S104). If it is determined that the amount of rotation of the pitch bender 122 is not zero ("NO" in step S104), the process of the CPU 40 proceeds to step S113. In such a case, the luminance of the emitted light color may already be in accordance with the amount of rotation of the pitch bender 122 at the time of the process of step S113. In this case, the CPU 40 does not need to reset the luminance value, and may simply return the process to step S102 after the timing for changing the luminance value has arrived.

[0054] If it is determined in the determination process of step S104 that the amount of rotation of the pitch bender 122 is zero ("YES" in step S104), the CPU 40 determines whether or not the luminance value is being changed according to a normal change pattern (step S105). If it is determined that the luminance value is not being changed according to a normal change pattern ("NO" in step S105), the process of the CPU 40 proceeds to step S113.

[0055] If it is determined that the luminance value has been changed according to the normal change pattern ("YES" in step S105), the CPU 40 acquires the next luminance value according to the normal change pattern based on the emission color information 52 (step S106). Then, the process of the CPU 40 proceeds to step S107.

[0056] As described above, the electronic keyboard instrument 1 of this embodiment includes the power switch 111 of the operation reception unit 10 that receives an input operation, the touch encoder 61 as a notification unit, and the CPU 40. The CPU 40 executes an operation stop process as a first process when the duration of detection of a continuous input operation becomes equal to or longer than a reference time, executes a transition process to a standby state as a second process when the duration of detection ends before the reference time, and, when the continuous input operation begins to be detected, causes the display unit of the touch encoder 61 to notify the user so that it is possible to determine whether the duration of detection is equal to or longer than the reference time. In this way, when an electronic musical instrument accepts different operation requests according to the detection duration of an input operation, it is difficult to know whether the necessary input operation has been performed and the operation will continue for the required duration, so by performing a notification operation in which the notification content changes so that it is possible to determine whether the duration is equal to or longer than a reference time using the touch encoder 61 or the like, the user can more reliably perform an input operation that is equal to or longer than the required detection duration. Therefore, with the electronic keyboard instrument 1, the user can more clearly know the change in the operation acceptance content.

[0057] The notification unit has a display unit 60, and the CPU 40 changes the stage of the notification operation by changing the length of the line displayed by the display unit 60 according to the detection duration of the input operation. Since the user can easily know the detection duration of the input operation, particularly the degree of the detection duration of the input operation relative to a reference time, from the length of the line displayed in this manner, the user can determine whether or not the input operation has been continued for the reference time or longer, and can continue the input operation for the reference time or longer or end it within the reference time with peace of mind.

[0058] Moreover, the above-mentioned line, which is displayed while changing its length, is displayed in a circular shape. This makes it possible to prevent the display area from being too large, and in particular to prevent overlapping of the display area with other displays.

[0059] The electronic keyboard instrument 1 also includes a touch encoder 61, which is included in the notification unit. By using such a module element, even an electronic instrument that has low processing power other than that related to performance can more easily perform real-time display operations.

[0060] Moreover, the CPU 40 executes a process of stopping the operation of the own device as a first process. In this way, by using the input operation for turning off the power supply in the same operation as other input operations and requesting a continuous operation for a reference time or more, it is possible to suppress an unintentional operation stop and also to suppress an increase in the number of operation keys, etc. Then, the user can know the remaining operation duration required when actually wanting to turn off the power supply, so that the user can perform the power supply operation with peace of mind.

[0061] As a second process, the CPU 40 executes a transition process to a standby state in which the operation related to the performance is stopped. That is, a transition from a normal operation state to a standby state is executed in response to a short operation less than the reference time. It is convenient to make the transition to the standby state, which allows easy return to performance, correspond to such a simple operation. Furthermore, by associating an operation longer than the reference time with the stop of operation, the power switch 111 is also used to switch the power supply state, which makes it easy to associate the operation contents and makes it easy for the user to use.

[0062] The electronic keyboard instrument 1 also includes a rotating wheel such as a pitch bender 122 that receives a rotation operation, a pitch bender light emitting unit 31 that is located inside the pitch bender 122 and emits light to the outside of the pitch bender 122, and a power switch light emitting unit 32 that illuminates the inside or surrounding area of ​​the power switch 111. The CPU 40 stops the operation of the power switch light emitting unit 32 in the standby state. In this way, by leaving the pitch bender light emitting unit 31 emitting light instead of the power switch 111 in the standby state, the user can easily tell from the operating parts related to performance that the standby state has been turned off with functions related to performance.

[0063] Furthermore, the pitch bender light emitting unit 31 can change the color of the light it emits, and the CPU 40 may change the color of the light emitted by the pitch bender light emitting unit 31 during the standby state. By changing the display state in this way, it becomes easier for the user to notice, and it is possible to prevent the user from forgetting to turn off the power supply.

[0064] The rotating wheel includes the pitch bender 122 or a modulation wheel. It is not an operation acceptance unit for basic functions like the power switch 111, but it is possible to change the lighting state of the pitch bender 122 related to the performance, so it can be used efficiently for production purposes in combination with changes in the lighting state when the pitch bender 122 is in use.

[0065] The electronic keyboard instrument 1 also includes a keyboard 121 that accepts input operations for specifying the pitch of the sound to be output. In other words, by using the above-mentioned configuration and display control for the keyboard instrument, the user can easily confirm and understand the operation state on the same keyboard surface as the upward-facing keyboard.

[0066] Furthermore, the method for notifying the operation status of the electronic musical instrument of this embodiment, which includes an operation receiving unit 10 (power switch 111) that receives input operations and a touch encoder 61, executes a first process when the duration of detection of a continuous input operation becomes equal to or longer than a reference time, executes a second process when the duration of detection ends before the reference time, and, when a continuous input operation begins to be detected, notifies the touch encoder 61 so as to be able to determine whether the duration of detection is equal to or longer than the reference time. In this way, when accepting different operation requests according to the detection duration of an input operation to the operation acceptance unit 10 (here, the power switch 111) in the electronic musical instrument, by performing different notification operations so as to be able to determine whether the detection duration is equal to or longer than a reference time using the touch encoder 61 or the like, the user can more reliably know whether a necessary input operation has been performed and whether the operation has continued for equal to or longer than the reference time, and can perform an input operation for equal to or shorter than the reference time. Therefore, according to this method of notifying the operation status of the electronic musical instrument, the user can more clearly know from the electronic musical instrument the switching status of the acceptance content of the operation request for the operation while the power switch 111 is being operated (long pressed).

[0067] Furthermore, by installing and executing the program 51 relating to the above-mentioned operation status notification method in the computer of the electronic musical instrument, the user can easily and clearly, without hassle, learn from the electronic musical instrument of the change in the acceptance content of the action request for the operation while operating (holding down) the power switch 111, using the conventional configuration.

[0068] The present invention is not limited to the above-described embodiment, but may be modified in various ways. For example, in the above embodiment, the long press time of a push button switch is described as the object of judgment, but the present invention is not limited to this as long as the judgment is based on the duration of an input operation. For example, the present invention may be a slide switch or a lever that automatically returns to a reference position when the user stops operating the switch.

[0069] In the above embodiment, the case where the transition from the normal operation state to the stopped state and the standby state is switched according to the detection duration of the same operation has been described as an example, but the present invention is not limited to this. When switching between a plurality of other function operations is switched according to the detection duration of a certain operation, the display operation may be performed according to the detection duration. In this case, the transition to the stopped state occurs when the operation is continued for a reference time or more, but the function executed when the operation is continued for less than the reference time may be something other than the transition to the standby state.

[0070] In the above embodiment, the display of the circle C has been described as being performed by the touch encoder 61, but this is not limiting. It may be displayed in another part of the display unit 60. Also, instead of displaying the circle C, it may be displayed as another closed figure such as an ellipse, a polygon, or a polygon with rounded corners, or it may be displayed as a straight line, a curved line, a broken line, or the like with both ends open (however, it is preferable that the user can easily know the positions of both ends).

[0071] In the above embodiment, the length of the line of the circle C is shortened to allow the user to know the ratio of the duration of the operation to the reference time, but this is not limited to the above. For example, the duration of the operation may be known by making a display such as a point or a line appear at the upper end (left end) of the display range and moving it to the lower end (right end) of the display range. The display color may be changed from blue to red, or the luminescence intensity of the display point or line may be reduced. Alternatively, in addition to the length or position, the area of ​​the displayed area may be changed. The displayed area may be erased from a circle to a sector, or a square may be erased vertically, horizontally, or diagonally. Furthermore, instead of changing the area of ​​the displayed figure, the area of ​​the area of ​​the figure whose display color is to be changed may be changed (increased).

[0072] In addition, such a notification action according to the detection duration of the input operation is not limited to a display action. For example, the notification action may be an audio output that lowers the pitch from a certain pitch by a predetermined width such as one octave, allowing the degree of the detection duration relative to a reference time to be known. The change in pitch in such audio output may be according to a musical scale or may be continuous.

[0073] Furthermore, the notification action does not have to change in multiple stages according to the detection duration up to the reference time as described above, but simply needs to be able to distinguish whether an input operation is detected or not and whether the duration at the time of detection is longer or shorter than the reference time.

[0074] Furthermore, after the detection duration reaches the reference time, the notification operation may be performed by stopping the emission of the light emitting part of the touch encoder 61 (different from the lighting state in the normal operation state). In this case, particularly, when the operation is ended before the detection duration reaches the reference time, it is preferable to perform a notification operation for a certain period of time that indicates that the detection duration was less than the reference time.

[0075] Alternatively, the notification operation may be stopped when the detection duration reaches the reference time (i.e., the notification operation essentially notifies only that the detection duration is not equal to or longer than the reference time). Conversely, the notification unit such as the touch encoder 61 may perform a specific operation (such as a lighting operation or a sound output operation) for a certain period of time to indicate that the detection duration has reached the reference time or longer. In this case, the operation stop process may be executed in parallel with the specific operation, or may be started after the specific operation is completed (after a certain period of time has elapsed).

[0076] In addition, in the above embodiment, the pitch bender and / or modulation wheel is used as an example of the rotating wheel, but the present invention is not limited to this and may be configured in another rotatable manner.

[0077] Also, while the description has been given of the color of light emitted by the pitch bender light-emitting unit 31 (the color of light emitted from the window L) slowly changing when power is being supplied and the pitch bender 122 is not being operated, it does not necessarily have to change continuously. Light of a fixed color may be emitted from the window L, or the color may change temporarily. Also, the pitch bender light-emitting unit 31 may flash, or the light emission intensity may change without changing the color.

[0078] Moreover, it does not have to be the pitch bender light-emitting section 31 that continues to light up even in the standby state. It may be the power switch light-emitting section 32 or another display section. In addition, the electronic keyboard instrument 1 may not have the pitch bender light-emitting section 31 or the pitch bender 122 itself.

[0079] In the above embodiment, the speaker 72 is capable of outputting sound in the standby state, but the present invention is not limited to this. A state in which some operations are stopped or restricted compared to the normal operation state to reduce power consumption may be called a standby state. In addition, the degree to which the display of the display unit 60 is stopped or the degree to which the light emission of the light-emitting unit 30 is stopped may be determined according to rules different from those in the above embodiment, depending on the content of the restriction.

[0080] In the above embodiment, the electronic musical instrument has been described as being the electronic keyboard instrument 1 having the keyboard 121, but the electronic musical instrument is not limited to this. It may be a stringed instrument such as a guitar having strings, a wind instrument, or the like.

[0081] In the above description, the storage unit 50 is exemplified as a computer-readable medium for storing the program 51 related to the notification control at the time of receiving an operation of the present invention, and is composed of a non-volatile memory such as an HDD or a flash memory, but is not limited thereto. As other computer-readable media, other non-volatile memories such as MRAM and portable recording media such as CD-ROMs and DVD disks can be applied. In addition, a carrier wave is also applied to the present invention as a medium for providing the data of the program according to the present invention via a communication line. In addition, the specific configurations, contents and procedures of the processing operations, etc. shown in the above embodiments can be modified as appropriate without departing from the spirit of the present invention. The scope of the present invention includes the scope of the invention described in the claims and its equivalents.
