[0017] In the guidance display of the above-mentioned patent document, the notified information is only the timing of key pressing. Consider, for example, the following situation: when multiple information such as information related to the user's performance operation (for example, information on the strength of the key pressing, etc.), performance auxiliary information (for example, the display of a metronome, etc.) are switched and displayed on one display unit, the information required by the user is not displayed.

[0018] In a display device of an electronic musical instrument, it is desired to display information necessary for a user well.

[0019] Hereinafter, a mode for carrying out the present invention will be described using the drawings.

[0020] However, the embodiments described below are limited to various technically preferred embodiments for carrying out the present invention.

[0021] Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrations.

[0022] [Structure of Electronic Musical Instrument 100]

[0023] Figure 1 1 is a block diagram showing the functional structure of an electronic musical instrument 100 including the display device of the present invention. Figure 2 1 is a diagram showing an example of the appearance structure of the electronic musical instrument 100. Figure 1 and Figure 2 As shown, the electronic musical instrument 100 is configured to include at least one processor such as a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a keyboard 14, an operation unit 15, a display unit 16, a sound system 17, a communication unit 18, and a pedal 19, and each unit is connected via a bus 20. The electronic musical instrument 100 includes the components of the display device of the present invention.

[0024] The CPU 11 (control section) reads out the programs and data stored in the ROM 12, and uses the RAM 13 as a work area to perform various processes, thereby centrally controlling each section of the electronic musical instrument 100. For example, the CPU 11 outputs the sound of a musical instrument such as a piano through the sound system 17 based on the operation of the keys of the keyboard 14 and the operation of the pedal 19 (performance operation). In addition, the CPU 11 reproduces music based on audio data as an input signal input from an external device via the communication section 18 through the sound system 17. In addition, as a performance aid, the CPU 11 outputs (reproduces) a demonstration performance of a song selected by the operation of the operation section 15 through the sound system 17. In addition, the CPU 11 causes the display section 16 to display a metronome display in accordance with a metronome reproduction instruction generated by the operation of the operation section 15. In addition, the CPU 11 records the user's performance based on the operation of the keys of the keyboard 14 and the operation of the pedal 19, etc. (records (stores) the user's performance information in a recording buffer (not shown) of the RAM 13) in accordance with a recording instruction based on the operation section 15, and causes the sound system 17 to reproduce the recorded user's performance in accordance with the operation of the operation section 15. The CPU 11 also controls the display of the display unit 16 by executing a display control process described later in cooperation with a program stored in the ROM 12 .

[0025] The ROM 12 stores programs and various data. For example, the ROM 12 stores a program for executing the display control process described later. In addition, the ROM 12 stores a plurality of information that can be displayed on the display unit 16 and information on the display mode of the display unit 16 corresponding to each information in association. The RAM 13 provides a storage space for the CPU 11 to work and temporarily stores data. In addition, the RAM 13 stores the user's performance information as a recording buffer, or stores setting information of various functions including the display setting of the display unit 16.

[0026] like Figure 2 As shown, the keyboard 14 is configured to include a plurality of keys (performance operation elements), and outputs information on key pressing / release and strength information (velocity) to the CPU 11 .

[0027] like Figure 2 As shown, the operation unit 15 includes various operation buttons and switches including a power button 151, and outputs operation signals corresponding to the user's operation of the operation buttons and switches to the CPU 11. Alternatively, the operation unit 15 may have a structure having an operation element that detects a tap of the user's finger based on a change in capacitance.

[0028] like Figure 2As shown, the display unit 16 is configured to include a plurality of light emitting units 161 (e.g., LEDs (Light Emitting Diodes)) arranged in a row in the arrangement direction of the keyboard 14, and each light emitting unit 161 is turned on or off according to the instruction of the CPU 11 to display predetermined information. In addition, the display unit 16 may be configured to further include an LCD (Liquid Crystal Display) or the like.

[0029] The sound system 17 is configured to include a sound source unit 171, an audio circuit 172, and a speaker 173. The sound source unit 171 reads waveform data (audio data) pre-stored in the ROM 12 or generates waveform data according to the control instruction from the CPU 11, and outputs it to the audio circuit 172. The audio circuit 172 performs D / A conversion on the waveform data (audio data) output from the sound source unit 171 and amplifies it, and the speaker 173 outputs the amplified analog sound. The speakers 173 are arranged on the left and right sides of the electronic musical instrument 100 (not shown), and the sound signal of the left sound source based on the audio data is output from the left speaker, and the sound signal based on the right sound source is output from the right speaker. When the audio data is monaural, the sound signal based on the audio data is output from the left speaker and the right speaker.

[0030] The communication unit 18 performs data transmission and reception with external devices such as external terminals connected via a communication network such as the Internet, Bluetooth (registered trademark) or a USB (Universal Serial Bus) cable.

[0031] The pedal 19 includes, for example, a damper pedal, and outputs information on the on / off state and the amount of pedal depression to the CPU 11 .

[0032] [Operation of the electronic musical instrument 100]

[0033] Next, the display control in the electronic musical instrument 100 is described. In the display unit 16, the display mode of the display unit 16 is changed by lighting or extinguishing each of the plurality of light emitting units 161, so that one of the plurality of information classified into the following groups A to D can be displayed. In other words, the display unit 16 displays one of the plurality of information, and does not display two or more of the plurality of information at the same time.

[0034] Group A (first information): information related to the user's playing operation (information such as the strength (force) of the keys (on the keyboard 14) pressed by the user, the degree of depression of the pedal 19, the volume of audio data input from an external device, etc.)

[0035] Group B (second information): information to assist in playing (such as the display of a metronome, the strength (force) of the keys pressed during demonstration playing, and the playback position of the recorded user's playing)

[0036] Group C (third information): information on setting values ​​when setting functions of the electronic musical instrument 100 (information on currently set setting values), notification information on abnormality (waiting / error / Bluetooth connection or disconnection, etc.)

[0037] Group D (fourth information): Information notifying the electronic musical instrument 100 of whether the power is turned on or off

[0038] Figure 3A and Figure 3B 1 is a diagram showing an example of a display mode corresponding to information indicating the strength of a key played by a user, information indicating the degree of depression of a pedal, and information indicating the strength of a key played in a demonstration performance on the display unit 16. Figure 3A and Figure 3B to Figure 5 In the figure, the shaded 0 indicates that it emits light (lit) at a prescribed luminous intensity weaker than the white 0. The white 0 indicates that it emits light at the maximum luminous intensity. The black 0 indicates that it does not emit light (extinguishes). The display unit 16 of the present embodiment is lit or extinguished in units (referred to as luminous units) composed of three adjacent light-emitting units 161. When lit, the center of the three light-emitting units 161 is lit at the maximum luminous intensity, and the two sides thereof are lit at a prescribed luminous intensity weaker than the center. Through a filter not shown in the figure, the three light-emitting units 161 that are lit appear to be one connected light. In addition, by lighting the light-emitting units 161 on both sides with a luminous intensity weaker than the center, a display without a sense of incongruity can be performed even when the adjacent light-emitting units are extinguished or when the light-emitting units at the ends are lit.

[0039] Figure 3A An example of display is shown when a key is pressed at the intensity of level 1, which is the lowest among seven levels, or when the pedal 19 is stepped on at the stepping degree of level 1. Figure 3B An example of display of a case where a key is pressed at a strength of level 7 (the highest level) or a case where the pedal 19 is stepped on at a stepping degree of level 7 is shown. Figure 3A and Figure 3B As shown in FIG. 1 , information indicating the strength of the key and information indicating the degree of depression of the pedal 19 are expressed by the number of light-emitting portions 161 lit from the left. Figure 3A As shown in FIG. 1 , when the strength of the key or the degree of stepping on the pedal 19 is weak, only the three light-emitting units 161 (light-emitting units) on the left are lit, and the remaining light-emitting units 161 are off. As the strength of the key and the degree of stepping on the pedal increase, the number of lights increases toward the right. When the number of lights reaches the highest level, as shown in FIG. Figure 3B As shown, all the light emitting units 161 are in a state of emitting light (lit up).

[0040] Figure 41 is a diagram showing an example of a display method of a metronome in the display unit 16. Figure 4 As shown, in the metronome display, the display of the light-emitting unit at the left end and the light-emitting unit at the right end is repeatedly lit alternately at a set rhythm.

[0041] Figure 5 FIG. 1 is a diagram showing an example of a display method of error information on the display unit 16. Figure 5 As shown, in the display of the error information, the display of lighting up / extinguishing the light-emitting units separated by one light-emitting unit is repeated every predetermined time (for example, 0.25 seconds).

[0042] As described above, in the display unit 16, a plurality of different information is displayed by switching through a plurality of different display modes (lighting / extinguishing of the light emitting unit 161). Figure 3A As described in , sometimes a plurality of different information are displayed by the same display mode. Therefore, it is conceivable that the user will be confused because he does not know what information is currently displayed in the display unit 16. In addition, it is also conceivable that the information required by the user may not be displayed.

[0043] Therefore, in this embodiment, the priority order is set in advance for the above-mentioned groups A to D, and control is performed so that the CPU 11 executes Figure 6 The display control process shown is performed so that the information of the group with a high priority is displayed preferentially. As a result, the user can understand what information is currently displayed on the display unit 16. In addition, information necessary for the user can be displayed.

[0044] For example, for the user, it is necessary to give priority to the information of the performance assistance of the group B, such as the display of the metronome or the information of the strength of the keys in the demonstration performance, compared with the information related to the performance operation of the group A. In addition, when the user sets the function, the information of the group C indicating which setting value is the current setting state is more important to the user than the information related to the performance operation of the user or the performance assistance information. In addition, when an abnormal state such as waiting, error, connection or disconnection of Bluetooth occurs in the electronic musical instrument 100, the user needs to immediately recognize the state. In addition, since it is impossible to perform, perform assistance, set, etc. in the startup process of turning on the power and in the process of cutting off the power, it is necessary to notify the user with the highest priority. Therefore, in the present embodiment, the priority of display is set to group D>group C>group B>group A, and the CPU 11 controls to give priority to the information of the group with the higher priority. The information in each group is controlled exclusively in a manner that it will not be displayed at the same time based on the display setting of the user.

[0045] The display setting can be set, for example, by the user operating the operation unit 15 or the like. The set information is stored in the RAM 13. For example, in the display setting of group A, one of "automatic", "fixed force", "fixed pedal" and "fixed audio illumination" can be set. In the present embodiment, when the information of group A can be displayed, when "automatic" is set, information indicating the strength (force) of the key is displayed on the display unit 16. When "fixed force" is set, information indicating the strength (force) of the key is displayed on the display unit 16. When "fixed pedal" is set, information indicating the degree of depression of the pedal 19 is displayed on the display unit 16. When "fixed audio illumination" is set, information indicating the volume of audio data input from an external device is displayed on the display unit 16.

[0046] In addition, for example, in the display setting of group B, one of "automatic" or "fixed metronome" and "fixed force" can be set. In the present embodiment, in the case where the information of group B can be displayed, when "automatic" is set, the display of the metronome is displayed on the display unit 16 during the reproduction of the metronome, and when the demonstration performance is reproduced without the metronome, the information indicating the force in the demonstration performance is displayed on the display unit 16. When "fixed metronome" is set, the display of the metronome is displayed on the display unit 16 during the reproduction of the metronome. When "fixed force" is set, the information indicating the force in the demonstration performance is displayed on the display unit 16 during the reproduction of the demonstration performance. In addition, in group B, regardless of the above display setting, the information indicating the reproduction position of the recorded user performance is given the highest priority, and the information indicating the reproduction position of the recorded user performance is displayed on the display unit 16 during the reproduction of the recorded user performance.

[0047] Below, refer to Figure 6 The display control process is described below. The display control process is executed by the CPU 11 and the program stored in the ROM 12 in cooperation when the power button 151 of the electronic musical instrument 100 is pressed and the power is turned on.

[0048] First, the CPU 11 causes the display unit 16 to display information notifying that the power is turned on (step S1). Specifically, during the startup period due to the power being turned on, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, and causes the plurality of light emitting units 161 to display in a prescribed display mode corresponding to the information notifying that the power is turned on, thereby causing the display unit 16 to display the information notifying that the power is turned on.

[0049] Next, the CPU 11 determines whether a long press of the power button 151 is detected (step S2 ).

[0050] In step S2, if it is determined that the long press of the power button 151 is not detected (step S2; No), the CPU 11 determines whether an event that should display the information of group C has occurred (step S4). The event that should display the information of group C is the occurrence of an abnormality or the function setting operation.

[0051] When it is determined that an event has occurred that should display the information of group C (step S4; yes), the CPU 11 starts the display processing of the information of group C (step S5), and returns to step S2. For example, when an abnormality occurs, as the display processing of the information of group C, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, and makes the plurality of light emitting units 161 display in a prescribed display mode corresponding to the information notifying the abnormality that has occurred. For example, when an error occurs, the CPU 11 makes the light emitting unit 161 turn on / off. Figure 5 The display mode shown is displayed. Thus, the display unit 16 displays information notifying that an abnormality has occurred. For example, when a function setting operation is performed through the operation unit 15 or the keyboard 14, as a display process of group C, the CPU 11 controls the lighting / extinguishing of each of the multiple light-emitting units 161 on the display unit 16, and causes the multiple light-emitting units 161 to display in a prescribed display mode corresponding to the set value of the function currently being set. Thus, the display unit 16 displays information on the set value when the function is set. In addition, when an abnormality occurs and a function setting operation occurs at the same time, the CPU 11 causes the display unit 16 to display information on one side based on a predetermined priority order.

[0052] When it is determined that no event has occurred for displaying the information of group C (step S4; No), CPU 11 determines whether an event has occurred for displaying the information of group B (step S6). Events for displaying the information of group B are the start of metronome reproduction, the start of demonstration performance reproduction, and the start of reproduction of a recorded user performance.

[0053] When it is determined that an event that should display the information of group B has occurred (step S6; Yes), the CPU 11 determines whether the display process of the information of group C is being performed (step S7). When it is determined that the display process of the information of group C is being performed (step S7; Yes), the CPU 11 returns to step S2. When it is determined that the display process of the information of group C is not being performed (step S7; No), the CPU 11 starts the display process of the information of group B (step S8).

[0054] Figure 7 2 is a flowchart showing the flow of the display process of the information of group B. The display process of the information of group B is executed by the cooperation of the CPU 11 and the program stored in the ROM 12 .

[0055] First, the CPU 11 determines whether the recorded user performance has started to be reproduced (step T101 ). The recorded user performance is started to be reproduced in response to the user's operation of a predetermined switch or the like on the operation unit 15 .

[0056] When it is determined that the recorded user performance has started to be reproduced (step T101; Yes), the CPU 11 starts display processing of information indicating the reproduction position of the recorded user performance (step T102), and returns to the Figure 6 For example, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, and causes the plurality of light emitting units 161 to display in a predetermined display mode corresponding to the current playback position in the recorded user performance. Thus, the display unit 16 displays information indicating the playback position of the recorded user performance.

[0057] When determining that the reproduction of the recorded user performance has not started (step T101 ; NO), the CPU 11 proceeds to step T103 .

[0058] In step T103 , the CPU 11 determines whether or not the reproduction of the metronome has started (step T103 ). The reproduction of the metronome starts in response to the user's operation of a predetermined switch or the like of the operation unit 15 .

[0059] If it is determined that the metronome playback has started (step T103; YES), the CPU 11 determines whether the display setting of group B is "automatic" (step T104). If it is determined that the display setting of group B is "automatic" (step T104; YES), the CPU 11 proceeds to step T106.

[0060] If it is determined that the display setting of group B is not "automatic" (step T104; No), CPU 11 determines whether the display setting of group B is "fixed metronome" (step T105). If it is determined that the display setting of group B is not "fixed metronome" (step T105; No), CPU 11 returns to Figure 6 When it is determined that the display setting of group B is "fixed metronome" (step T105; Yes), the CPU 11 proceeds to step T106.

[0061] In step T106, the CPU 11 determines whether the recorded user performance is being reproduced (step T106). That is, the CPU 11 determines whether information indicating the reproduction position of the user performance is being displayed on the display unit 16. If it is determined that the recorded user performance is being reproduced (step T106; yes), the CPU 11 returns to step T106. Figure 6 Step S2.

[0062] If it is determined that the recorded user performance is not reproduced (step T106; No), the CPU 11 starts the metronome display process (step T107), and returns to the Figure 6 For example, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, and causes the plurality of light emitting units 161 to display in a prescribed manner (for example, referring to Figure 4 ) to display, so that the display unit 16 displays the metronome display.

[0063] On the other hand, when it is determined that the reproduction of the demonstration performance has already started (step T108; yes) instead of the metronome reproduction (step T103), the CPU 11 determines whether the display setting of the B group is "automatic" (step T109). In response to the user's operation of the specified switch of the operation unit 15, the reproduction of the demonstration performance starts.

[0064] If it is determined that the display setting of group B is "automatic" (step T109; Yes), the CPU 11 determines whether the metronome is being reproduced (step T110). That is, the CPU 11 determines whether the metronome is being displayed on the display unit 16. If it is determined that the metronome is being reproduced (step T110; Yes), the CPU 11 returns to the Figure 6 If it is determined that the metronome is not being played back (step T110; No), the CPU 11 proceeds to step T112.

[0065] If it is determined that the display setting of group B is not "automatic" (step T109; No), the CPU 11 determines whether the display setting of group B is "fixed force" (step T111). If it is determined that the display setting of group B is not "fixed force" (step T111; No), the CPU 11 returns to Figure 6 When it is determined that the display setting of the group B is "fixed strength" (step T111; YES), the CPU 11 proceeds to step T112.

[0066] In step T112, the CPU 11 determines whether the recorded user performance is being reproduced (step T112). That is, the CPU 11 determines whether information indicating the reproduction position of the user performance is being displayed on the display unit 16. If it is determined that the recorded user performance is being reproduced (step T112; yes), the CPU 11 returns to step T113. Figure 6 If it is determined that the recorded user performance is not being reproduced (step T112; No), CPU 11 performs display processing of information indicating the strength (force) of the keys in the demonstration performance (step T113), and returns to step S2. Figure 6For example, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, so that the plurality of light emitting units 161 are displayed in a prescribed display mode (for example, referring to FIG. 1 ) corresponding to the strength of the key in the demonstration performance. Figure 3A , Figure 3B ) is displayed. Thus, the display unit 16 is made to display information indicating the strength of the key pressed during the demonstration performance.

[0067] Return to Figure 6 In step S6, when it is determined that no event has occurred for displaying the information of group B (step S6; No), CPU11 determines whether an event has occurred for displaying the information of group A (step S9). When it is determined that no event has occurred for displaying the information of group A (step S9; No), CPU11 returns to step S2. When it is determined that an event has occurred for displaying the information of group A (step S9; Yes), CPU11 determines whether the information of group C is being displayed (step S10). When it is determined that the information of group C is being displayed (step S10; Yes), CPU11 returns to step S2. When it is determined that the information of group C is not being displayed (step S7; No), CPU11 determines whether the information of group B is being displayed (step S8). When it is determined that the information of group B is being displayed (step S11; Yes), CPU11 returns to step S2. When it is determined that the information of group B is not being displayed (step S11 ; No), the CPU 11 executes a display process of the information of group A (step S12 ), and the process returns to step S2 .

[0068] Figure 8 2 is a flowchart showing the flow of the display process of the information of group A. The display process of the information of group A is executed by the cooperation of the CPU 11 and the program stored in the ROM 12 .

[0069] First, CPU11 determines whether a key operation (performance operation) is detected on the keyboard 14 (step T201). When it is determined that a key operation is detected on the keyboard 14 (step T201; yes), CPU11 determines whether the display setting of group A is "automatic" (step T202). When it is determined that the display setting of group A is "automatic" (step T202; yes), CPU11 transfers to step T204. When it is determined that the display setting of group A is not "automatic" (step T202; no), CPU11 determines whether the display setting of group A is "fixed force" (step T203). When it is determined that the display setting of group A is not "fixed force" (step T203; no), CPU11 returns to step T204. Figure 6When it is determined that the display setting of group A is "fixed strength" (step T203; Yes), the CPU 11 proceeds to step T204.

[0070] In step T204, the CPU 11 executes a display process of information indicating the strength (force) of the key being played by the user (step T204), and then returns to step T205. Figure 6 For example, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 in the display unit 16, and makes the plurality of light emitting units 161 display in a predetermined display mode (for example, referring to Figure 3A , Figure 3B ) is displayed, so that the display unit 16 displays information indicating the strength of the key pressed by the user during the performance.

[0071] On the other hand, when it is determined that no key operation is detected on the keyboard 14 (step T201; No), the CPU 11 determines whether the operation of the pedal 19 is detected (step T205). When it is determined that the operation of the pedal 19 is detected (step T205; Yes), the CPU 11 determines whether the display setting of the A group is "pedal fixed" (step T206). When it is determined that the display setting of the A group is not "pedal fixed" (step T206; No), the CPU 11 returns to Figure 6 If it is determined that the display setting of group A is "pedal fixed" (step T206; yes), CPU 11 performs display processing of information indicating the degree of depression of pedal 19 (step T207), and returns to step S2. Figure 6 For example, the CPU 11 controls the lighting / extinguishing of each of the plurality of light emitting units 161 on the display unit 16, and makes the plurality of light emitting units 161 display in a predetermined display mode corresponding to the degree of depression of the pedal 19 (for example, refer to Figure 3A , Figure 3B ) is displayed, so that the display unit 16 displays information indicating the degree of pedal depression.

[0072] On the other hand, when it is determined that the operation of the pedal 19 is not detected (step T205; No), the CPU 11 determines whether audio data from an external device is input through the communication unit 18 (step T208). When it is determined that audio data from an external device is not input through the communication unit 18 (step T208; No), the CPU 11 returns to step T206. Figure 6 Step S2.

[0073] If it is determined that audio data from an external device is input via the communication unit 18 (step T208; Yes), the CPU 11 determines whether the display setting of group A is "fixed audio lighting" (step T209). If it is determined that the display setting of group A is not "fixed audio lighting" (step T209; No), the CPU 11 returns to Figure 6 If it is determined that the display setting of group A is "fixed audio lighting" (step T209; yes), CPU 11 performs a display process of the volume of the input audio (step T210), and returns to Figure 6 Step S2.
