Description

[Technical Field]

[0001] The present invention relates to an electronic musical instrument operating device capable of operating any parameter related to the output of a tone generator section provided in an electronic musical instrument. [Background technology]

[0002] Electronic musical instruments are configured to store waveform data for strikes based on the sounds of specific natural musical instruments such as acoustic drums and cymbals, and to output the stored waveform data when a strike is detected during performance. Such electronic musical instruments are usually equipped with a sound source unit that outputs any sound based on the strike during performance from a speaker or headphones.

[0003] However, conventionally, electronic musical instrument operating devices that allow an operator to arbitrarily operate parameters (such as volume and sound effects) related to the output of a sound source unit equipped in an electronic musical instrument are disclosed, for example, in Patent Documents 1 and 2. Such electronic musical instrument operating devices display the parameters of an authenticated electronic musical instrument on a touch panel display screen, and by touching a predetermined portion on the screen (a display portion imitating a button), the volume and pitch can be increased or decreased, and by touching and moving another portion (a display portion imitating a slider) up or down, the volume and pitch can be adjusted in real time.

[0005] However, in the above-mentioned conventional electronic musical instrument operating device, since touch operations on the touch panel are reflected in the electronic musical instrument in real time, if the touch panel is accidentally touched while playing the electronic musical instrument, there is a risk that the parameter will be changed to an extreme value, which could interrupt the performance or cause excessive volume, potentially damaging the equipment. Furthermore, in the process of manipulating the parameters, control signals for changing the parameters are sent and received successively and frequently, which could have an adverse effect on the sound generation process and sound generation speed of the sound source unit.

[0006] The present invention has been made in consideration of the above circumstances, and its purpose is to provide an electronic musical instrument operating device that can prevent parameters from being changed to extreme values ​​even when the touch panel is touched unintentionally and accidentally, and that can suppress adverse effects on the sound generation processing and sound generation speed of the sound source unit. [Means for solving the problem]

[0007] The invention of claim 1 is an electronic musical instrument operating device capable of operating any parameter related to the output of a sound source section of an electronic musical instrument, comprising: a display section that displays a current value of the parameter of the electronic musical instrument in a first display format; a touch panel type input section that allows a desired value of the parameter of the electronic musical instrument to be input; a display control section that displays the desired value of the parameter of the electronic musical instrument inputted by the input section on the display section in a second display format different from the first display format; and a reflection section that reflects the current value of the parameter of the electronic musical instrument to the desired value in response to an operation by an operator. a determination unit that determines whether the parameter of the electronic musical instrument has been changed to the desired value; and the display control unit is configured to perform a reflection operation to reflect the parameter of the electronic musical instrument to the desired value. and the determining unit determines that the parameter of the electronic musical instrument has been changed to the desired value. The display device is characterized in that, under the condition that the desired value is changed from the second display mode to the first display mode on the display unit.

[0009] Claim 2 The invention described is 1st articleIn the electronic musical instrument operating device described above, the electronic musical instrument is provided with a plurality of playing sections, and the display control section is capable of individually controlling the display of the plurality of playing sections.

[0011] Claim 3 The invention described is 1st article In the electronic musical instrument operating device described above, the input unit is capable of inputting a plurality of desired values ​​of the parameters of the electronic musical instrument, and the reflection unit reflects the plurality of desired values ​​collectively, subject to operation by an operator.

[0012] Claim 4 The invention described is 1st article In the electronic musical instrument operating device, the parameters are the volume, tone quality, musical tones, sound effects, output destination settings, and adjustment items for the performance parts of the electronic musical instrument.

[0013] Claim 5 The invention described is 1st article The electronic musical instrument operating device is characterized in that it comprises an external operating terminal connected to the sound source unit of the electronic musical instrument by wire or wirelessly. [Effects of the Invention]

[0014] Claim 1 of According to the invention, the electronic musical instrument is provided with a reflection unit that reflects the parameters of the electronic musical instrument from their current values ​​to desired values, provided that the operator operates the unit. Therefore, even if the touch panel is touched unintentionally by mistake, the parameters will not be reflected from their current values ​​to the desired values ​​unless the operator operates the reflection unit, thereby preventing the parameters from being changed to extreme values. In addition, since the parameters are not reflected sequentially during the operation process, but only the desired values ​​are reflected, it is possible to prevent adverse effects on the sound generation process and sound generation speed of the sound source unit.

[0015] Also, Claim 1According to the invention, the electronic musical instrument includes a determination unit that determines whether a parameter of the electronic musical instrument has been changed to a desired value, and the display control unit, on the condition that the determination unit determines that the parameter of the electronic musical instrument has been changed to the desired value, returns the desired value displayed in the second display form on the display unit to the display in the first display form, thereby allowing the operator to understand that the parameter of the electronic musical instrument has been changed to the desired value. On the other hand, if it is determined that the parameter of the electronic musical instrument has not been properly reflected in the desired value for some reason, the desired value remains displayed in the second display form, allowing the operator to try again to reflect the desired value.

[0016] Claim 2 According to the invention, the electronic musical instrument is equipped with multiple playing parts, and the display control unit is capable of individually controlling the display of the multiple playing parts, so this invention can be effectively applied to electronic musical instruments with multiple playing parts, such as electronic drums.

[0017] Claim 3 According to the invention, the input unit is capable of inputting multiple desired values ​​for parameters of an electronic musical instrument, and the reflection unit reflects multiple desired values ​​all at once, subject to operation by the operator. This allows multiple parameters to be changed instantaneously compared to reflecting each parameter sequentially, reducing the hassle of performing reflection operations one by one, and allowing the desired values ​​of multiple parameters that are to be changed simultaneously to be confirmed before being reflected.

[0018] Claim 4 According to the invention, the parameters are the volume, sound quality, musical tones, sound effects, output destination settings, and adjustment items for the performance section of the electronic musical instrument, so these parameters can be reflected from their current values ​​to desired values ​​by operating the reflection section.

[0019] Claim 5 According to the invention, the electronic musical instrument operating device is comprised of an external operating terminal connected to the sound source unit of the electronic musical instrument by wire or wirelessly, so that the electronic musical instrument operating device can be disposed in any position different from the sound source unit, thereby further improving the operability of the electronic musical instrument operating device.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2, the electronic musical instrument operating device 1 according to the first embodiment is configured as a separate entity from the sound source section 4 of the electronic musical instrument 2, and is comprised of an external operating terminal connected wirelessly. In this embodiment, information necessary for performance (such as control signals) can be transmitted and received between the electronic musical instrument operating device 1 and the sound source section 4, for example, by radio waves or infrared rays, but the electronic musical instrument operating device 1 and the sound source section 4 may also be connected by wire.

[0022] The applicable electronic musical instrument 2 is capable of electronically generating percussion sounds and outputting them during performance, and in this embodiment has a playing section 3 consisting of electronic drums, electronic cymbals, etc., which can be played by the performer striking them with sticks, etc. Note that the playing section 3 of the applicable electronic musical instrument 2 may be other electronic musical instruments, such as percussion instruments such as electronic drums and electronic cymbals, keyboard instruments such as electronic pianos, string instruments such as electronic guitars, etc.

[0023] The playing unit 3 also has a striking section that can be struck during performance, and a vibration sensor that can detect striking of the striking section during performance and transmit a detection signal, and the detection signal detected by the vibration sensor is transmitted to the sound source unit 4. When the sound source unit 4 receives a detection signal from the playing unit 3, it is capable of outputting an output signal corresponding to the detection signal to a sound output unit S such as a speaker or headphones.

[0024] Furthermore, the tone generator 4 according to this embodiment is equipped with a display unit 10 that displays any parameter related to the electronic musical instrument 2, a control unit 11 that controls the parameters of the electronic musical instrument 2, and a reflection unit 12 that reflects the parameters of the electronic musical instrument 2 from their current values ​​to desired values. The parameters of the electronic musical instrument 2 are comprised of the volume, tone quality, musical tones, sound effects, output destination settings, and adjustment items of the performance unit 3, and are freely adjustable.

[0025] For example, when the performance unit 3 is struck during a performance, a detection signal generated by the strike is sent to the sound source unit 4, which generates an output signal corresponding to the detection signal, causing the desired musical tone to be output from the sound output unit S, and parameters such as volume to be displayed on the display unit 10. Then, when a desired value is input into the parameter of the electronic musical instrument 2 by operating the reflection unit 12, the parameter can be changed from its current value to the desired value under the control of the control unit 11.

[0026] On the other hand, the electronic musical instrument operating device 1 of this embodiment consists of an external operating terminal (see Figures 5 to 7) wirelessly connected to the sound source unit 4 of the electronic musical instrument 2, and is capable of remotely operating any parameters related to the output of the sound source unit 4 equipped in the electronic musical instrument 2 (the volume, sound quality, musical tones, sound effects, output destination settings, and adjustment items of the performance unit 3 of the electronic musical instrument 2), and is also equipped with a display unit 5 consisting of a display screen, an input unit 6 that can sense touch operations on the display unit 5 and input them, a display control unit 7 consisting of a microcomputer or the like, a reflection unit 8 that can be operated by the operator through touch, and a judgment unit 9 also consisting of a microcomputer or the like.

[0027] The display unit 5 displays the current values ​​of the parameters of the electronic musical instrument 2 in a first display mode, and is made up of a liquid crystal screen capable of displaying various letters, numbers, and designs, for example, as shown in Figures 5 to 7. As shown in Figures 5 to 7, the display unit 5 displays a plurality of sections (areas) representing each playing section 3, and each section displays a letter (such as "Crash1," "Hi-Hat," "Ride," "T1," "Kick," or "Snare") to indicate the type of playing section 3.

[0028] In this embodiment, any parameter of the playing section 3 (numbers indicating volume in Figs. 5 to 7) is displayed in the area (region) indicating the playing section 3, and the current value of the parameter is displayed as a white number (first display form). For example, in Fig. 5, the current volume value of "Crash 3" of the electronic musical instrument 2 is "85," the current volume value of "Hi-Hat," and the current volume value of "Snare" are "80."

[0029] The input unit 6 is a touch panel type that allows desired values ​​for parameters of the electronic musical instrument 2 to be input, for example, by touching a predetermined portion displayed on the display unit 5 with a finger. For example, input is performed by touching a portion indicating the performance unit 3 whose parameters are to be adjusted with a finger, and the touched performance unit 3 can be selected. When a performance unit 3 is selected by touching, the display range of the selected performance unit 3 is surrounded by a thick line, as shown in Figures 5 to 15. In addition, an adjustment unit L is displayed on the display unit 5, and by touching and moving the adjustment unit L up or down, the parameter of the selected performance unit 3 can be increased or decreased to input a desired value.

[0030] The display control unit 7 displays the desired parameter values ​​of the electronic musical instrument 2 inputted by the input unit 6 on the display unit 5 in a second display form different from the first display form, and for example, as shown in Fig. 6, the desired parameter values ​​are displayed as numbers displayed in black (second display form). That is, when a user touches and selects a portion representing an arbitrary playing part 3, and then touches and operates the adjustment unit L to input a desired value, the display control unit 7 displays the desired value in the second display form (black display form) in the portion (area) representing the playing part 3 whose parameter has been changed.

[0031] 6, for example, the desired volume value for "Crash 3" of the electronic musical instrument 2 is "65," the desired volume value for "Hi-Hat" is "70," and the desired volume value for "Snare" is "82," and each number is displayed in a black display form (second display form). Note that in the areas (regions) showing the performance parts 3 whose parameters have not been changed, each number is displayed in white (first display form).

[0032] The reflection unit 8 reflects the parameters of the electronic musical instrument 2 from their current values ​​to desired values, subject to operation by the operator, and in this embodiment is displayed as a push button with the word "Send" displayed on the display unit 5. In other words, when the desired values ​​are displayed in the second display mode (blacked-out display mode), touching the reflection unit 8 causes information including the desired values ​​of the parameters to be sent to the sound source unit 4 of the electronic musical instrument 2.

[0033] When the tone generator 4 of the electronic musical instrument 2 receives information including desired parameter values, the control unit 11 changes the parameters from their current values ​​to the desired values, and the volume of the output from the sound output unit S is changed to the desired value. For example, in this embodiment, the volume of "Crash 3" of the electronic musical instrument 2 is changed from "85" to "65," the volume of "Hi-Hat" from "80" to "70," and the volume of "Snare" from "50" to "82."

[0034] The determination unit 9 determines whether the parameter of the electronic musical instrument 2 has been changed to a desired value. In this embodiment, when the control unit 11 completes changing the parameter, a completion notification signal is transmitted from the sound source unit 4. When the electronic musical instrument operating device 1 receives this completion notification signal, the electronic musical instrument operating device 1 then requests the current value from the sound source unit 4, whereupon the determination unit 9 determines whether the reflected current value matches the corresponding desired value, and determines whether the parameter of the electronic musical instrument 2 has been changed to the desired value.

[0035] Here, the display control unit 7 according to this embodiment is configured to return the desired value displayed in the second display form on the display unit 5 to the display in the first display form, on the condition that a reflection operation for reflecting the parameter of the electronic musical instrument 2 to the desired value has been performed. Specifically, the display control unit 7 reflects the parameter from its current value to the desired value by touching the reflection unit 8, and then, on the condition that the determination unit 9 determines that the parameter of the electronic musical instrument 2 has been changed to the desired value, returns the desired value displayed in the second display form (black display form) on the display unit 5 to the display in the first display form (white display form). For example, in this embodiment, "Crash 3," "Hi-Hat," and "Snare" of the electronic musical instrument 2 are returned from being displayed as black numbers to being displayed as white numbers.

[0036] Furthermore, the input unit 6 according to this embodiment is capable of inputting a plurality of desired values ​​for the parameters of the electronic musical instrument 2, and the reflection unit 8 is capable of reflecting the plurality of desired values ​​collectively, subject to operation by the operator. In this embodiment, as shown in Fig. 6, desired values ​​for a plurality of parameters, "Crash3," "Hi-Hat," and "Snare," can be input, and by touching the reflection unit 8, the plurality of desired values, "Crash3," "Hi-Hat," and "Snare," can be transmitted collectively to the tone generator unit 4 of the electronic musical instrument 2 and reflected therein.

[0037] As described above, the first and second display modes may be white numbers and black numbers, respectively. Alternatively, as shown in Fig. 8, the first display mode may be one where there is no circle in the area (region) representing the playing unit 3, and the second display mode may be one where there is a circle. Also, as shown in Fig. 9, the first display mode may be one where the area (region) representing the playing unit 3 displays a pattern corresponding to the adjustment unit L, and the first display mode may be one where the pattern is displayed in white, and the second display mode may be one where the pattern is displayed in black. Additionally, the first display state may be a constant display, and the second display state may be a flashing display.

[0038] Furthermore, in addition to controlling the volume of the electronic musical instrument 2, it may also be capable of controlling other parameters, for example, controlling the sound quality of the electronic musical instrument 2 as shown in Figures 10 to 12, or controlling the sensitivity of the electronic musical instrument 2 as shown in Figures 13 to 15.

[0039] For example, when manipulating the sound quality of the electronic musical instrument 2, the current value of the sound quality is displayed in the first display form (white numbers) on each part representing the performance unit 3 as shown in Fig. 10, and a desired value is input by touching a desired part, and the desired value is displayed in the second display form (black numbers) as shown in Fig. 11. Then, by touching the reflection unit 8, the sound quality is reflected from the current value to the desired value, and then, provided that the reflection result is correct, the sound quality displayed in the second display form (black numbers) is returned to the first display form (white numbers) as shown in Fig. 12.

[0040] Furthermore, for example, when adjusting the sensitivity of the electronic musical instrument 2, the current sensitivity values ​​are displayed in the first display format (white numbers) at each part representing the performance unit 3 as shown in Fig. 13, and a desired value is input by touching a desired part, and the desired value is displayed in the second display format (black numbers) as shown in Fig. 14. Then, by touching the reflection unit 8, the sensitivity is reflected from the current value to the desired value, and after that, provided that the reflection result is correct, the sensitivity displayed in the second display format (black numbers) is returned to the first display format (white numbers) as shown in Fig. 15.

[0041] Next, the control content of the electronic musical instrument operating device 1 according to this embodiment will be described with reference to the flowcharts shown in FIGS. First, in S1, the electronic musical instrument operating device 1 requests the current value of a parameter from the sound source unit 4, and upon receiving the request signal, the sound source unit 4 transmits the current value of the requested parameter (Sa). If the electronic musical instrument operating device 1 is unable to receive the current value, it will repeatedly request the current value. In this case, the number of retries can be preset. Then, in S2, it is determined whether or not the current value has been received. If it is determined that the current value has been received, the process proceeds to S3, where the current value is displayed in the first display form (white-out display form) (see FIG. 5). At this time, touch operations on the reflection unit 8 are disabled, so that even if the reflection unit 8 is accidentally touched, no input operation will be performed.

[0042] Thereafter, in S4, it is determined whether or not a desired value has been input, and if it is determined that a desired value has been input, the process proceeds to S5, where the input desired value is displayed in the second display form (blacked-out display form) (see FIG. 6). At this time, touch operations on the reflection unit 8 are validated, and input is possible by touch operations on the reflection unit 8. Then, in S6, it is determined whether or not a touch operation has been performed on the reflection unit 8, and if it is determined that a touch operation has been performed, the desired value is transmitted to the electronic musical instrument 2 in S7.

[0043] When the electronic musical instrument 2 receives the desired value, it reflects the desired value in Sb, changes the parameter from the current value to the desired value, and then transmits a completion notification signal to the electronic musical instrument operation device 1 in Sc. Thereafter, it is determined in S8 whether or not the completion notification signal has been received. If it is determined that the completion notification signal has been received, in S9 the electronic musical instrument operation device 1 requests the current value of the parameter from the sound source unit 4, and upon receiving the request signal, the sound source unit 4 transmits the current value of the requested parameter (Sd). If the electronic musical instrument operation device 1 does not receive the completion notification signal, it will transmit the desired value to the electronic musical instrument 2 again, but in this case the number of retries can be preset.

[0044] Then, in S10, it is determined whether or not a current value has been received. If it is determined that a current value has been received, the process proceeds to S11, where the received current value is compared with the desired value, and it is determined in S12 whether or not the received current value matches the desired value. If the current value matches, the display returns to the first display format (white-out display format) in S13, and if the current value does not match, the display of the desired value continues in the second display format (black-out display format) in S14 (see FIG. 6).

[0045] After S13 or S14, in S15 it is determined whether the desired value is displayed in the second display form (blacked-out display form), and if it is determined that the desired value is displayed in the second display form, the process returns to S6 and the subsequent steps are performed again, and if it is determined that the desired value is not displayed in the second display form, the process disables the touch operation on the reflection unit 8 in S16, and then the process returns to S4 and the subsequent steps are performed again.

[0046] According to this embodiment, the electronic musical instrument 2 is provided with a reflection unit 8 that reflects the parameters of the electronic musical instrument 2 from their current values ​​to desired values, provided that the operator operates the unit. Therefore, even if the touch panel is touched unintentionally by mistake, the parameters will not be reflected from their current values ​​to the desired values ​​unless the operator operates the reflection unit 8, thereby preventing the parameters from being changed to extreme values. In addition, since the parameters are not reflected sequentially during the operation process, but only the desired values ​​are reflected, adverse effects on the sound generation process and sound generation speed of the sound source unit 4 can be suppressed.

[0047] Furthermore, the electronic musical instrument 2 is provided with a determination unit 9 that determines whether the parameters of the electronic musical instrument 2 have been changed to the desired values, and the display control unit 7, on the condition that the determination unit 9 determines that the parameters of the electronic musical instrument 2 have been changed to the desired values, returns the desired values ​​displayed in the second display form on the display unit 5 to the display in the first display form, so that the operator can understand that the parameters of the electronic musical instrument 2 have been changed to the desired values, and, if there are any parameters that have not been changed to the desired values, can perform the operation again to reflect the parameters to the desired values. In particular, since the electronic musical instrument 2 is provided with multiple playing units 3 and the display control unit 7 is capable of individually controlling the display of the multiple playing units 3, the electronic musical instrument 2 can be well applied to electronic musical instruments having multiple playing units 3, such as electronic drums.

[0048] Furthermore, the input unit 6 allows input of multiple desired values ​​for the parameters of the electronic musical instrument 2, and the reflection unit 8 reflects multiple desired values ​​collectively, subject to operation by the operator, so that multiple parameters can be changed instantaneously compared to reflecting each parameter sequentially, and it is possible to prevent adverse effects on the sound generation process and sound generation speed of the sound source unit 4. Note that, although multiple desired values ​​are reflected collectively in this embodiment, it is also possible to reflect a single desired value.

[0049] Furthermore, since the parameters applied in this embodiment are the volume, sound quality, musical tones, sound effects, output destination settings, and adjustment items of the performance unit 3 of the electronic musical instrument 2, these parameters can be reflected from their current values ​​to desired values ​​by operating the reflection unit 8. Note that the applied parameters are not limited to the volume, sound quality, musical tones, sound effects, output destination settings, and adjustment items of the performance unit 3 of the electronic musical instrument 2, but may be any other parameters. In addition, according to this embodiment, the electronic musical instrument operation device 1 is comprised of an external operation terminal connected by wire or wirelessly to the sound source unit 4 of the electronic musical instrument 2, so that the electronic musical instrument operation device 1 can be disposed in any location different from the sound source unit 4, thereby further improving the operability of the electronic musical instrument operation device 1.

[0050] 16 to 18, an electronic musical instrument operating device 1 according to a second embodiment of the present invention is configured as a separate entity from the sound source section 4 of the electronic musical instrument 2 and is comprised of an external operating terminal connected wirelessly. In this embodiment, information necessary for performance (such as control signals) can be transmitted and received between the electronic musical instrument operating device 1 and the sound source section 4 by, for example, radio waves or infrared rays, but the electronic musical instrument operating device 1 and the sound source section 4 may also be connected by wire.

[0051] Note that the same components as those in the first embodiment (specifically, the display unit 5, input unit 6, and reflection unit 8) are given the same reference numerals, and detailed descriptions thereof will be omitted. Also, the applied electronic musical instrument 2 (including the sound source unit 4, etc.) is the same as that in the first embodiment, and detailed descriptions of such electronic musical instrument 2 will also be omitted.

[0052] When a desired value of a parameter of the electronic musical instrument 2 is input via the input unit 6, the display control unit 7' changes the display state from a first state to a second state to indicate whether or not the desired value is present. For example, as shown in Figures 17 and 18, when a user touches and selects a portion representing a desired performance unit 3 and then touches and operates the adjustment unit L to input a desired value, the display control unit 7' changes the display state in the upper part of the display unit 5 from the first state, in which an open circle is displayed, to the second state, in which a filled circle is displayed. At this time, the display form of the parameter of the desired value does not change as in the first embodiment.

[0053] The first and second display states are not limited to the above-described open circle and filled circle displays, and other forms of display may be used in other locations. Furthermore, when a desired value is input, the display state of the reflection unit 8 may change (for example, from a display indicating that touch operations are not permitted to a display indicating that touch operations are permitted). In this case, the display state in which touch operations are not permitted in the reflection unit 8 is the first display state, and the display state in which transmission by touch operations is permitted is the second display state.

[0054] The restoration unit 13 restores a desired value that is not reflected in the electronic musical instrument 2 to a current value, subject to operation by the operator, and is displayed in the upper part of the display unit 5 and can be operated by the operator by touching it, as shown in Figures 17 and 18. When a touch operation is performed, the restoration unit 13 according to this embodiment requests the current value from the sound source unit 4, and receives the current value, thereby restoring the desired value to the current value. Alternatively, the current value before the desired value was input may be temporarily stored, and the desired value may be restored to the stored current value by touching the restoration unit 13.

[0055] The determination unit 9' determines whether there are any desired values ​​that have not been reflected in the electronic musical instrument 2. Here, the display control unit 7' according to this embodiment is configured to return the display on the display unit 5 from the second display state to the first display state (i.e., change the display from the second display form displaying filled circles to the first display form displaying open circles) on the condition that the determination unit 9' determines that there are no desired values ​​that have not been reflected in the electronic musical instrument 2.

[0056] According to this embodiment, as in the first embodiment, a reflection unit 8 is provided that reflects the parameters of the electronic musical instrument 2 from their current values ​​to desired values, provided that the operator operates the unit. Therefore, even if the touch panel is touched unintentionally by mistake, the parameters will not be reflected from their current values ​​to the desired values ​​unless the operator operates the reflection unit 8, thereby preventing the parameters from being changed to extreme values. In addition, since the parameters are not reflected sequentially during the operation process, but only the desired values ​​are reflected, adverse effects on the sound generation process and sound generation speed of the sound source unit 4 can be suppressed.

[0057] Furthermore, according to this embodiment, the restoration unit 13 is provided, so that the desired value can be restored to the current value as needed. Therefore, even under conditions where it is not possible to switch between the first and second display states for each performance unit 3 due to limitations such as color or space, if the operator forgets which performance unit 3 he or she operated, the state before the change can be easily restored, making it possible to input an accurate desired value. Note that, although in this embodiment, multiple desired values ​​are reflected collectively, it is also possible to reflect a single desired value.

[0058] While the present embodiment has been described above, the present invention is not limited to this, and may be, for example, an electronic musical instrument operation device 1 that is integrated with the sound source section 4 of the electronic musical instrument 2, as shown in Figures 19 and 20.
