In the present embodiment, in the key range setting switch unit 13B, as shown in FIG. 4, the setting by the part switch 41 is set for each of four key ranges (hereinafter, the key range is referred to as “Zone”, and each of the four key ranges is set to Zone 1). Through 4), the light emission state can be set, and the presence or absence of light emission in the set key range can also be set. It is also possible to set a timbre separately. In that case, the key range setting switch unit 13B may be configured to be provided with a switch for selecting a timbre.
In this embodiment, as shown in each part switch 41, the key range setting switch unit 13B performs color coding of the key range by changing the color as shown in FIG. In the drawing, the state of color coding of the key range is indicated by hatching IP1 to IP4. For example, the vertical hatching IP1 indicates that the color is “red”, the left diagonal hatching IP2 indicates that the color is “green”, and the cross hatching IP3 is “blue”. The dot hatching IP4 indicates that the color is “pink”.

In the example of FIG. 4, the key range is set by first pressing the part switch 41 so that the key range can be set. Then, by pressing the Low switch 42, a key (lower limit key) corresponding to a sound with a low key range to be set is set, and then a key corresponding to a high key range sound to be set by pressing the High switch 43 ( Set the upper limit key. That is, in the electronic musical instrument 1, the key range setting process is started by pressing the part switch 41, and the corresponding key 100 is operated (key pressing) by pressing the Low switch 42 and the High switch 43. As a result, a key number corresponding to a later-described key range setting table in the RAM 18 is stored. The electronic musical instrument 1 controls the light emission of the light emitting unit 12 with reference to the key range setting table. It is also possible to set various timbres separately for the set key range.
In addition, by pressing the LED button 44 of the key range setting switch unit 13B, it is possible to set whether or not each region emits light.

Next, an example of the key range setting table will be described.
FIG. 5 is a schematic diagram illustrating an example of a key range setting table.
As shown in FIG. 5, the key range setting table stores Zone 1 to Zone 4 indicating areas where each key emits light in the same color (hereinafter referred to as a key area), and settings for determining whether or not to emit light in each key area. The
In the “Low” column, the scale pressed as the lower limit key is stored as the lower limit value.
In the “High” column, the scale pressed as the upper limit key is stored as the upper limit value.
The “Part” column stores the presence / absence of light emission. When the “Part” field is “ON”, the light emission is set, and when the “Part” field is “OFF”, the light emission is not set.
In the “Error” column, an Error flag value is stored as a verification result of the lower limit value and the upper limit value. In the “Error” column, it is abnormal when the lower limit value exceeds the upper limit value, that is, when the key of the higher scale is stored as the lower limit value and the key of the lower scale is stored as the upper limit value. The error flag value “Yes” indicating that the setting is invalid is stored. In response to the result, if the “Part” field is “ON”, it is set to “OFF”, and processing for not emitting light is performed.
On the other hand, in the “Error” column, when the lower limit value does not exceed the upper limit value, that is, when the key of the lower scale is stored as the lower limit value and the key of the higher scale is stored as the upper limit value, it is normal. The error flag value “No” indicating that the setting is valid is stored.

In the example of FIG. 5, in “Zone 1”, the lower limit key (“Low”) is the key of the scale of “F # 3”, and the upper limit key (“High”) is the key of the scale of “B7”. The presence / absence of sound generation (“Part”) is “ON”, and the setting abnormality (“Error”) is “No”.
In “Zone 2”, the lower limit key (“Low”) is the key of the scale of “F # 3”, the upper limit key (“High”) is the key of the scale of “E6”, and there is no sound. (“Part”) is “ON”, and the setting abnormality (“Error”) is “No”.
In “Zone3”, the lower limit key (“Low”) is the key of the scale of “C2”, the upper limit key (“High”) is the key of the scale of “F3”, and the presence or absence of the sound (“ “Part”) is “ON”, and the setting abnormality (“Error”) is “No”.
In “Zone4”, the lower limit key (“Low”) is the key of the scale of “C2”, the upper limit key (“High”) is the key of the scale of “G2”, and the presence / absence of sound (“ “Part”) is “ON”, and the setting abnormality (“Error”) is “No”.
Therefore, in the example of FIG. 5, the key range in which “Zone 1” to “Zone 4” is set is a target region for split performance that outputs a tone different from the default tone (piano in this example). It is. In addition, there are areas where the settings overlap in “Zone 1”, “Zone 2”, “Zone 3”, and “Zone 4”, but this area is the target of layer performance in which a plurality of sounds are output with one key 100. It is a key range. That is, the split performance and the layer performance are set at the same time, and as shown in FIG. 4, the light emitting units 12 are lit in two rows with the key 100 in the corresponding area.

Next, the flow of performance processing executed by the electronic musical instrument 1 as described above will be described.
FIG. 6 is a flowchart showing an example of the flow of performance processing executed by the electronic musical instrument 1 of FIG.
Here, the performance process is a series of processes in which settings related to performance (key light display and tone color settings) are performed, and display processing and sound generation processing are performed based on the settings.
In the present embodiment, a performance mode can be assigned to each key. As performance modes that can be assigned, “normal performance mode”, “split performance mode”, and “layer performance mode” can be set.
The “normal performance mode” is a mode in which a tone similar to that of a piano is assigned to each key and can be played with the same feeling as a piano.
The “split performance mode” is a mode in which a sound different from a piano such as a sound of an instrument other than a piano is assigned to each key.
The “layer performance mode” is a mode in which a plurality of sounds are assigned to keys.

  The performance process is started when the start of the performance process is instructed by a predetermined operation on the switch unit 13 by the performer, and the following process is executed.

  In step S1, the CPU 16 performs an initialization process. Specifically, the CPU 16 performs various initial settings for the electronic musical instrument 1.

In step S2, the CPU 16 performs switch processing including key range setting processing.
The switch process refers to a process of selecting a predetermined option for a mode in which a plurality of options exist or changing a sound quality to be sounded by a predetermined operation of the performer on the switch unit 13. Of the switch processes, the key range setting process is a process for setting whether or not the key 100 emits light. The key range setting process will be described later.

In step S <b> 3, the CPU 16 refers to a key range setting table stored in the RAM 18 and performs a keyboard lighting process for performing light emission control of the light emitting units 12 corresponding to the keys 100. Specifically, the CPU 16 refers to the key range setting table as shown in FIG. 5 and controls the light emission of the light emitting unit 12 in the key range corresponding to the key range (Zone) in which “Part” is “ON”. . As a result, in the electronic musical instrument 1, as shown in FIG. 1, the light emitting unit 12 emits light corresponding to each key 100, and the performance mode ("normal performance mode", "split performance mode" or "layer performance mode"). ]) Can be intuitively recognized. In the example of FIG. 1, the “split performance mode” is set for the key 100 that emits light, and the “layer performance mode” is set for the key 100 that emits light in two rows. In addition, although not shown, the “normal performance mode” is set for the key 100 that does not emit light.
Specifically, in the example of FIG. 5, the CPU 16 emits the light emitter 12 (lower LED 12-1) so that the range from “F # 3” to “B7” is displayed in red as “Zone1”. Controls the light emission.
Further, the CPU 16 controls the light emission of the light emitter 12 (upper LED 12-2) so that the range from “F # 3” to “E6” is displayed as “Zone2” in green.
Further, the CPU 16 controls the light emission of the light emitter 12 (lower LED 12-1) so that the range from “C2” to “F3” is displayed as blue with “Zone3”.
Further, the CPU 16 controls the light emission of the light emitter 12 (upper LED 12-2) so that the range from “C2” to “G2” is displayed as “Zone4” in pink.
As a result, as shown in FIG. 1, the keyboard 11 is displayed in different colors corresponding to the modes assigned to the predetermined range.

  In step S <b> 4, the CPU 16 performs a key press / key release detection process for detecting key presses and key releases to the key 100.

  In step S <b> 5, the CPU 16 performs a sound generation / mute process that performs sound generation and mute in the sound source unit 15 based on the key depression and key release detected in step S <b> 4. Thereafter, the performance process ends.

Next, the flow of the key range setting process executed by the electronic musical instrument 1 will be described.
FIG. 5 is a flowchart showing an example of a key range setting process executed by the electronic musical instrument 1 of FIG. In FIG. 5, only one zone assignment will be described.

In step S21, the CPU 16 determines whether or not the part switch 41 has been pressed.
If the part switch 41 has not been pressed, the process is NO in step S21, the key range setting process is terminated, and the process returns to step S2.
On the other hand, when the part switch 41 is pressed, the process is YES in step S21, and the process proceeds to step S22. For example, when the performer presses the part switch 41 of “Zone 1”, the setting of the key range to be emitted is started.

In step S22, the CPU 16 determines whether or not the Low switch 42 has been pressed.
If the Low switch 42 is not pressed or the Exit button is pressed, NO is determined in step S22, and the process proceeds to step S26. The process of step S26 will be described later.

  On the other hand, if the Low switch 42 is pressed, YES is determined in step S22, and the process proceeds to step S23.

  In step S23, the CPU 11 sets the lower limit key by pressing the lower limit key 100. That is, when the lower limit key 100 is pressed, the CPU 11 stores the scale number of the pressed key 100 in the “Low” column of the key range setting table.

In step S24, the CPU 16 determines whether or not the key of the high switch 43 has been pressed.
If the key of the high switch 43 is not pressed or the Exit button is pressed, NO is determined in step S24, and the process proceeds to step S26.

  On the other hand, if the high switch 43 is pressed, YES is determined in step S24, and the process proceeds to step S25.

  In step S23, the CPU 11 sets the upper limit key by pressing the upper limit key 100. That is, when the upper limit key 100 is pressed, the CPU 11 stores the scale number of the pressed key 100 in the “High” column of the key range setting table.

In step S26, the CPU 16 verifies the settings. Specifically, the CPU 16 refers to the key range setting table and verifies whether the upper limit and lower limit settings are appropriate. At this time, if a key whose scale is higher than “Low” is set, it is determined that the key is normal, and an Error flag value “No” is displayed in the “Error” column of the key range setting table. Is stored.
On the other hand, when a key whose scale is lower than “Low” is set at this time, or when “High” is not set than “Low”, it is determined as abnormal. Then, the Error flag value “Yes” is stored in the “Error” column of the key range setting table. That is, when the Error flag value “No” is registered, the setting is valid, that is, the light emission control is enabled. When the Error flag value “YES” is registered, the setting is invalid, that is, The light emission control is not performed.
In the example of FIG. 5, since each “Zone” setting is appropriate, “No” is stored in the “Error” column.

  In step S27, the CPU 16 reflects the verification result. Specifically, the value of the key range setting table is changed based on the result of verification in step S26. Specifically, when “Yes” is stored in the “Error” column, the CPU 16 sets “Part” from “ON” to prevent the light emitting unit 12 from emitting light with an abnormal setting. Change to “OFF”. Thereby, the key range setting process ends, and the process returns to step S2.
