As shown in this figure, the electronic keyboard instrument 1 includes an input unit 40, a display unit 50, an audio output unit 60, a storage unit 70, and a control unit 80.

  The input unit 40 includes the plurality of keys 21, the plurality of operators 24 and the three pedals 31 described above, and the position of the depressed key 21 or the pedal 31 or the operated operator 24 or the operation amount thereof ( A key depression speed and a pedal depression amount are detected, and a signal corresponding to this is output to the control unit 80.

  The display unit 50 includes the above-described plurality of light emitting units 211 corresponding to the plurality of keys 21 and performs lighting by controlling lighting of the plurality of light emitting units 211 based on a control signal from the control unit 80. It displays various information about musical tones.

The sound output unit 60 includes a sound source unit 61 and a speaker 62.
The sound source unit 61 generates a tone signal to be output from the speaker 62 based on the control signal from the control unit 80. More specifically, the tone source unit 61 generates a tone signal by applying a tone effect based on the operation on the pedal 31 and the operation element 24 to a signal based on a performance operation on the key 21.
The speaker 62 generates a musical tone based on the musical tone signal from the tone source unit 61.

The storage unit 70 is a memory that stores programs and data for realizing various functions of the electronic keyboard instrument 1 and also functions as a work area. In the present embodiment, the storage unit 70 stores a keyboard emission program 71.

  The control unit 80 centrally controls each part of the electronic keyboard instrument 1. Specifically, the control unit 80 reads various programs stored in the storage unit 70 according to an operation signal or the like input from the input unit 40, and turns on the light emitting unit 211 according to the program or the sound output unit 60. It outputs musical tones.

[Keyboard processing]
Subsequently, a keyboard emission process in which the electronic keyboard instrument 1 causes the key 21 to emit light will be described.
3 to 6 are flowcharts showing the flow of the keyboard light emission process, and FIGS. 7 and 8 are diagrams showing an example of the light emission state of the key 21 in the keyboard light emission process. 7 and 8 show only the light emitting portions 211 that emit light, and the illustration of the light emitting portion 211 not emitting light is omitted (however, the broken line portion in FIG. 8B). except for). Further, in FIG. 7 and FIG. 8, the key 21 whose key depression operation is performed is shown by an image in which a finger is attached to the tip.

The keyboard light emission process is a process of causing the key 21 to emit light in response to a user's operation of the musical tone operator, and is repeatedly executed in a short cycle. Here, the “tone operator” is an operator that applies a change to the tone generated by the performance operation to the key 21 and, in the present embodiment, the operator 24 of the operation unit 23 or the pedal unit 3 It is a pedal 31.
The keyboard light emission process is executed by the control unit 80 reading out the keyboard light emission program 71 from the storage unit 70 based on a user operation and expanding the program.

  As shown in FIG. 3, when a key depression operation is performed on any key 21 while the keyboard light emission processing is being performed (step S1), the control unit 80 is depressed by the input unit 40. The position of the key 21 is detected (step S2), and the pressing strength or speed (key pressing strength) of the key 21 is detected (step S3). Then, the control unit 80 causes the sound output unit 60 to generate the musical tone of the pitch corresponding to the key depression position at a volume corresponding to the key depression strength.

Next, the control unit 80 causes the light emitting unit 211 of the key 21 corresponding to the key depression position (pitch) detected in step S2 to emit light with the light emission pattern corresponding to the key depression intensity (volume) detected in step S3. (Step S4).
In the light emission pattern (light emission mode) at this time, in the present embodiment, as shown in FIG. 7A, the key 21 is made to emit light at a light emission intensity corresponding to the volume. However, the light emission pattern is not particularly limited as long as it corresponds to the volume, and for example, the blink rate corresponding to the volume (for example, the higher the volume is, the faster the blink is), or the emission color (for example, the higher the volume is darker) The key 21 may be made to emit light in color). Alternatively, as shown in FIG. 7B, it may be an indicator display that indicates the volume by the number of light emissions of the light emitting unit 211 of the plurality of keys 21 selected based on the key 21 operated as a key depression. The example of FIG. 7B shows a volume state of 3/7 in which the light emitting units 211 of the three keys 21 emit light with respect to the number of light emissions for 7 keys in total indicated by the broken line in the drawing.

Next, as shown in FIG. 3, the control unit 80 determines whether the volume knob 24a of the operation unit 23 is operated (step S5).
Then, when it is determined that the volume knob 24a is operated (Step S5; Yes), the control unit 80 detects the operation content (operation direction and operation amount) by the input unit 40, and according to the operation content, The volume to be output from the output unit 60 is changed (step S6).

At this time, the control unit 80 changes the light emission pattern of the key 21 emitted in step S4 in accordance with the change in the volume in step S6 (step S7).
In the present embodiment, since the key 21 is made to emit light at the emission intensity corresponding to the volume, the emission intensity of the key 21 is changed corresponding to the change content of the volume. When the light emission pattern is a blink rate, a light emission color, or an indicator display, these light emission patterns may be changed in response to changes in the volume. Alternatively, the key 21 may be made to emit light in a light emission pattern according to the combination of the key depression strength and the change content of the volume.
Thereby, the volume change of the musical tone can be notified, and the user (performer) can visually recognize the degree of the volume change.
Thereafter, the control unit 80 shifts the process to step S9 described later.

On the other hand, when it is determined in step S5 described above that the volume knob 24a is not operated (step S5; No), as shown in FIG. 4, the control unit 80 operates the modulation wheel 24b of the operation unit 23 It is determined whether or not it is (step S11).
When it is determined that the modulation wheel 24b has been operated (step S11; Yes), the control unit 80 detects the operation content by the input unit 40, and periodically changes the pitch according to the operation content. The vibrato is applied to the tone to be output from the voice output unit 60 (step S12).

Further, at this time, the control unit 80 changes the light emission pattern of the key 21 which has been lighted in step S4 in response to the vibrato operation (step S13).
Specifically, as shown in FIG. 7C, the control unit 80 causes the key 21 to emit light in a blinking cycle corresponding to the vibrato frequency. However, the light emission mode at this time may not be blinking as long as it can notify the vibrato frequency, and for example, as described above, the vibrato frequency is expressed by the light emission intensity or the light emission color of the light emitting unit 211 You may do it.
Thus, the vibrato of the musical tone can be notified, and the user (performer) can visually recognize the degree of vibrato.
Thereafter, the control unit 80 shifts the process to step S9 described later.

On the other hand, when it is determined in step S11 described above that the modulation wheel 24b is not operated (step S11; No), as shown in FIG. 5, the control unit 80 operates the pitch bend wheel 24c of the operation unit 23 It is determined whether or not it is (step S21).
When it is determined that the pitch bend wheel 24c has been operated (step S21; Yes), the control unit 80 detects the contents of the operation by the input unit 40, and the musical tone to be output from the voice output unit 60 according to the operation content. Is smoothly changed up and down (step S22).

At this time, the control unit 80 causes the key 21D at the key depression position and the other key 21A corresponding to the change direction of the pitch to emit light based on the change content of the pitch (step S23).
Specifically, as shown in FIG. 8A, the control unit 80 specifies another key 21A corresponding to the direction of change in pitch due to the pitch bend operation (in the example of FIG. Key 21b) The other key 21A is illuminated together with the key 21D at the key depression position.
At this time, as shown in the graph on the right side of FIG. 8A, the control unit 80 changes the key 21D at the key depression position and the other key 21A according to the change content of the pitch (the degree of engagement of the pitch bender). Each light is emitted at the same light emission intensity. However, the light emission mode at this time does not need to change the light emission intensity as long as it can notify the condition of the pitch bender. For example, as described above, the light emission color or the number of light emission or the blink speed It is also possible to express the degree of the pitch vendor's impact by means of, for example.
As a result, it is possible to notify of a change in pitch of the musical tone, and the user (performer) can visually recognize the degree of pitch bend.
Thereafter, the control unit 80 shifts the process to step S9 described later.

On the other hand, when it is determined in step S21 described above that the pitch bend wheel 24c is not operated (step S21; No), the control unit 80 determines whether the pedal 31 of the pedal unit 3 is operated as shown in FIG. It is determined (step S31).
When it is determined that the pedal 31 has been operated (step S21; Yes), the control unit 80 detects the operation content by the input unit 40, and a tone change corresponding to the operated pedal 31 and the operation content occurs. (Step S32).
For example, when the sostenuto pedal 31b is operated, the control unit 80 extends the tone of the key 21 which was pressed when the sostenuto pedal 31b is operated.

At this time, the control unit 80 causes the specific key 21 whose musical tone is changed by the pedal operation to emit light regardless of whether or not it is pressed at that time (step S33).
For example, as shown in FIG. 8B, the control unit 80 causes the key 21 whose key change is caused by the key operation to emit light and causes the key 21 to emit no sound change even when the key is pressed. 21 does not emit light as indicated by a broken line in the figure. At this time, the light emission state (for example, light emission intensity) of the key 21 causing the tone change is changed according to the state of the tone change (for example, the light emission intensity at the start of the tone change is the strongest, and the tone change is The light emission may be stopped when completing the process. However, the light emission mode at this time is not particularly limited.
This makes it possible to notify of a change in tone due to the pedal operation, and the user (performer) can visually recognize the effect.

Next, as shown in FIG. 3, the control unit 80 determines whether or not the key release operation of the key 21 pressed in step S1 is performed (step S9), and determines that the key release operation is not performed. If it is determined (step S9; No), the process proceeds to step S5 described above.
Then, when it is determined that the key release operation of the key 21 is performed (Step S9; Yes), the control unit 80 ends the keyboard light emission process for the key 21.

As described above, according to the present embodiment, when the player operates the operation unit 23 or the pedal unit 3, the light emitting unit 211 of the keyboard unit 22 emits light in a light emission mode according to the change content of the musical tone by the operation. Do.
As a result, it is possible to notify the content of the tone change due to the tone operation, and to allow the player to visually recognize the content of the tone change.

In addition, when the volume knob 24a is operated at the time of key depression operation, any one of the light emission intensity, the blink speed, the light emission color, and the number of light emission of the key 21 (light emission unit 211) changes based on the change content of the volume Do.
Thereby, it is possible to notify of the volume change of the musical tone, and the player can visually recognize the degree of the volume change.

In addition, when the modulation wheel 24b is operated at the time of key depression operation, the key 21 (light emitting unit 211) emits light in a blinking cycle corresponding to the vibrato frequency given to the musical tone.
Thus, the vibrato of the musical tone can be notified, and the player can visually recognize the degree of vibrato.

In addition, when the pitch bend wheel 24c is operated at the time of key depression operation, the light emitting portion 211 of the pressed key 21 and the other keys 21A corresponding to the change direction of the pitch are based on the change contents of the pitch. The light emitting unit 211 emits light.
As a result, it is possible to notify the change in pitch of the musical tone, and the player can visually recognize the degree of the pitch bender.

In addition, when the pitch bend wheel 24c is operated at the time of key depression operation, the light emitting unit 211 of the pressed key 21 and the light emitting unit 211 of the other keys 21A emit light with the light emission intensity corresponding to the change content of the pitch .
This enables the player to more easily visually recognize the pitch bender.

Further, when the pedal 31 is operated at the time of key depression operation, only the light emitting portion 211 of the key 21 which is the depressed key 21 and whose musical tone is changed by the operation of the pedal 31 emits light.
As a result, it is possible to notify of a change in tone due to the operation of the pedal (which key 21 the tone is changing), and the player can visually recognize the effect.

[Modification]
In the above embodiment, in the keyboard light emission process, when the pitch bend operation is performed, the change of the pitch is indicated at one time (in one light emission) in step S23. However, the stepwise change of the pitch is It is also possible to show.
In this case, as shown in FIG. 9, when it is determined that the pitch bend wheel 24c has been operated (step S21; Yes), the control unit 80 specifies the final change amount along with the change direction of the pitch (step S25). Then, the control unit 80 determines a stepwise change amount of pitch to be changed next (step S26). Then, the control unit 80 causes the light emission pattern (for example, the light emission amount) corresponding to the stepwise change amount of the light emission to emit light of the original sound pitch and the key corresponding to the finally changed sound pitch (step S27). . Thereafter, the control unit 80 determines whether or not the pitch has changed to the final change amount (step S28), and steps S26 and S27 may be repeated until the change occurs. That is, from the start of the change of the tone pitch to the completion of the tone pitch, the light emission intensity of the key 21 at the key depression position is gradually weakened while the light emission intensities of the other keys 21A are gradually increased. To go.
As a result, it is possible to notify the gradual pitch change of the musical tone, and the user (player) can visually recognize the gradual pitch change.

  Further, in the above-described embodiment, in the keyboard light emission processing, it is determined that the presence / absence determination of all the tone operations of volume operation, modulation operation, pitch bend operation, and pedal operation is included. However, the keyboard lighting process may include at least one of these musical tone operations.

Further, the modulation operation is not limited to applying vibrato to the tone, but may be another tone change such as tremolo, for example.
The pedal operation has been described using the sostenuto pedal 31b as an example, but as for the damper pedal 31a and the soft pedal 31c, the key 21 is emitted according to the degree of the tone effect as in the case of the sostenuto pedal 31b. Of course you should do it.

Further, the light emission mode of the light emitting unit 211 according to the change content of the musical tone is not limited to the above. For example, the light emission intensity of the key 21 (light emitting unit 211) may be weakened as the sound becomes smaller after keying. Further, when the musical tone changes, the light emitting unit 211 may be made to emit light according to the contents of the change, and the light emitting unit 211 may not emit light in advance when the key is depressed.
Furthermore, the light emitting unit 211 may not be provided to each of the plurality of keys 21 as long as the light emitting unit 211 is provided to the keyboard unit 22. However, it is, of course, preferable to correspond to a plurality of keys 21.
