Consequently, the user can notice immediately that an unintended velocity value is input in such a case. Further, not only input of music data, but also change of velocity information can be achieved using the input operation element. Consequently, the user can perform changing operation for the velocity information in operation mode similar to that of the input operation for the music data, so the user does not need to move his or her hand or line of sight large from the input operation element, and can smoothly change the velocity information.

Description

  The present invention relates to a music data input device for inputting music data generated in response to an operation of an input operator by a user. In particular, the present invention relates to a music data input device capable of setting and inputting a velocity value to a value corresponding to a user's operation intensity for a push-type input operator.

  Recently, an application program (for example, a DAW (Digital Audio Workstation) software program) that implements music production functions such as recording, editing, and mixing of musical tones using digital signals has been installed in electronic devices such as personal computers. By making the program run on a computer, anyone can easily enjoy making music (specifically, for example, generation of music data such as MIDI). In the music production process using such a program, data for drum parts and other percussion instrument parts are also input. A dedicated controller is prepared separately. The user can easily input music data of a percussion instrument part by connecting the controller to the computer and pressing (striking) the pad of the controller as necessary.

  When inputting music data of a percussion instrument part (for example, a drum part) according to the pad operation by the user, a velocity value that adds to the intensity of a musical tone is input as a musical tone control parameter in addition to note-on data and note-off data. This velocity value is set to a value (for example, 0 to 127) according to the operation intensity of the controller with respect to the pad of the controller. In general, the velocity value is one of the parameters having a great influence on the expressiveness of the music. Therefore, there has been a demand on the user side to advance the input of music data with an appropriate velocity value.

Conventionally, an LED (display) arranged directly under (or in the vicinity of) the pad is changed in luminance or display color in accordance with the user's operation intensity with respect to the pad, and the operated pad is lit. The user was trying to figure out whether the velocity value was input as intended from the brightness and display color of the LED when the pad was lit. An example of what is displayed by changing the brightness and display color of the LED in accordance with the operation intensity for such a pad is, for example, the technique described in Patent Document 1 shown below.
Also, if the user cannot change the velocity of the pad as intended, the velocity value can be changed by changing the velocity curve that defines the velocity value according to the user's strength of operation. It is necessary to be able to input the velocity value as intended. An example of what can change such a velocity curve itself is, for example, a technique described in Patent Document 2 shown below.

JP 2005-010812 JP JP 2009-008827 A

  However, in the prior art described in Patent Document 1 described above, the pad is lit by changing the display mode such as the luminance and display color of the LED in accordance with the operation intensity of the pad. It is merely an indirect guess by the user based on the lighting state of the LED according to the operation intensity of the pad, and it is difficult for the user to intuitively grasp the velocity value. In particular, the above problem is remarkable when the user operation intensity and the velocity value are not in direct proportion.

  In the prior art described in Patent Document 2 described above, the velocity curve is changed by operating a dedicated switch arranged at a position different from the input operator. Therefore, when you want to change the velocity curve while creating a song, the user must remove the hand and eyes from the input operator. There was a problem that music data could not be input.

  The present invention has been made in view of the above points, and relates to a velocity value to which a value according to a user's pad operation strength is input, and can be visually confirmed immediately when the user operates the pad. In addition, a music data input device that allows the user to easily change the velocity curve without greatly moving the operation position or line of sight when the intended velocity value cannot be input well and the user wants to change the velocity curve. The purpose is to provide.

  A music data input device according to the present invention stores a plurality of velocity information representing a correspondence relationship between a user operation intensity and a velocity value, and an input for instructing generation of music data including at least a velocity value according to a user operation. And a display means capable of displaying in a plurality of different display modes, and in response to an operation of the input operation element, a user operation intensity applied by the user to the input operation element is detected. Detecting means for determining, a determining means for determining a velocity value according to the detected user operation intensity based on the velocity information selected in advance, and changing and controlling the display mode of the display means based on the determined velocity value Control means for determining the velocity value of the input operator from the plurality of velocity information according to a user instruction. And allocating the means for selecting the velocity information to be used for.

  According to the present invention, the velocity value is determined according to the user operation intensity with respect to the input operation element added by the user during the operation based on the velocity information selected in advance, and a plurality of different displays are performed based on the determined velocity value. The display mode of the display means capable of displaying in the mode is changed and controlled. This makes it easier for the user to intuitively confirm the magnitude of the velocity value determined according to the operation strength of the input operator according to the display during operation. Further, the input operator operated for determining the velocity value can be assigned to a means for selecting velocity information used when determining the velocity value from among a plurality of velocity information according to a user instruction. did. According to this, since it becomes possible for the user to perform the velocity information changing operation in the same manner as the music data input operation, it is not necessary to move the position and line of sight of the hand from the input operator. Velocity information can be changed smoothly. Accordingly, the user can input music data efficiently.

  According to the present invention, since the change control for displaying the display means in a different display mode is performed based on the velocity value determined according to the user operation intensity with respect to the input operation element, the user operates the input operation element. The effect is that the magnitude of the velocity value determined according to the operation intensity can be confirmed immediately according to the display during operation. Furthermore, since the velocity curve can be changed using the input operator, the user inputs the operation position and line of sight when moving from the song data input operation to the velocity curve change operation. The velocity curve can be changed smoothly without having to be moved greatly from the operator.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  First, an outline of a music production system to which a music data input device according to the present invention is applied will be described with reference to FIG. FIG. 1 is a block diagram showing an embodiment of the overall configuration of a music production system to which a music data input device according to the present invention is applied. Note that although there may be a music production system other than that shown in FIG. 1, a case where the minimum necessary resources are used will be described here.

  A music production system shown in FIG. 1 includes a music data input device (hereinafter referred to as controller C), a personal computer (hereinafter referred to as computer P), and a music data processing device (here, electronic musical instrument D, digital mixer M, speaker O as an example). ). In this music production system, a controller C and a music data processing device (D, M, O) are connected to a computer P via communication interfaces, respectively, and between the controller C and the computer P, a computer P and a music data processing device ( D, M, O) can transmit / receive various data, signals, etc., and various information. The computer P may be a server device connected to a communication network such as the Internet.

  The controller C is a dedicated device for inputting music data, and has a plurality of pad-type input operators for data input (see FIG. 3 described later). The user can input music data of a drum part, for example, to the computer P by connecting the controller C to the computer P and performing an operation of pressing the pad of the controller C as necessary. That is, the controller C generates drum tone music data that has been assigned to each pad in advance in response to the user's pad operation, and transmits this to the computer P.

  The music production software program F (such as the above DAW) is installed on the computer P, and the music production software program F is operated to perform music production functions such as recording, editing, and mixing of musical sounds using digital signals. It is possible to implement. At the time of executing the music production function, not only is it possible to generate, for example, music data in response to the operation of the computer P being operated by the user, but as described above, the computer The music data of the drum part generated and transmitted in response to the operation of the external controller C connected to P by the user is captured (stored), and the captured music data and the music data generated on the computer P side Can be used to generate music data including one or more parts including at least drum part music data.

  The music data composed of one or more parts (or musical tone signal generated based on the music data) generated by the computer P is transmitted to each music data processing device (D, M, O) as needed, and each music The music data (or musical tone signal) can be used by the data processing device (D, M, O).

  In addition, the controller edit software program E is installed in the computer P, and the user has been assigned to each of the plurality of pads of the controller C connected to the computer P by operating the controller edit software program E. Can be confirmed on the computer P side (depending on the mode). That is, the computer P includes a display and is assigned to each of the plurality of pads of the controller C. For example, the type of drum tone of music data generated in response to the pressing operation of each pad in the “input mode”, Information relating to the velocity curve selected in the “velocity curve change mode” is displayed on the display. That is, since the controller C itself does not have a display and the user cannot check the detailed setting contents of the own device on the controller C side, the user can check the detailed setting contents of the controller C on the computer P side. I am doing so. It should be noted that it may be possible to instruct the computer P to change functions such as changing the timbre assigned to each pad of the connected controller P or changing the selectable velocity curve.

  The music production software program F and the controller edit software program E described above are not limited to computer software, and can be implemented in the form of a microprogram processed by a DSP (digital signal processor). The present invention is not limited to the form of a program, and may be implemented in the form of a dedicated hardware device configured to include a discrete circuit, an integrated circuit, a large-scale integrated circuit, or the like.

  FIG. 2 is a hardware configuration block diagram showing an embodiment of the music data input device. FIG. 3 is a conceptual diagram showing an embodiment of the overall configuration of the music data input device. As shown in FIG. 2, the music data input device (controller C) shown in this embodiment is a microcomputer comprising a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. Be controlled. The CPU 1 controls the operation of the entire apparatus. A ROM 2, a RAM 3, a detection circuit 4, a display circuit 6, and a communication interface (I / F) 8 are connected to the CPU 1 via a data and address bus 1D.

  The ROM 2 stores various control programs executed by or referred to by the CPU 1, various data, and the like. The RAM 3 is used as a working memory for temporarily storing various data generated when the CPU 1 executes a predetermined program, or as a memory for temporarily storing a currently executing program and related data. The A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like.

  The operation element 5 is a pad (5a) that is an input operation element that generates music data in response to, for example, detection of a tapping operation by the user, or various switches (for example, various types of switches that output various information in response to detection of a touch operation by the user 5b, 5c) and the like. The detection circuit 4 detects the presence / absence of a user operation on the operation element 5. For example, when the user performs a pressing operation on each pad 5a, ON / OFF and a detection output of the operation intensity at that time can be generated. When a user operation is performed on the various switches (5b, 5c), an on / off detection output can be generated. The pad 5a can be used not only for music data generation but also as a means for selecting a velocity curve (see FIG. 5 described later).

  As shown in FIG. 3, the controller C is provided with a plurality of thin plate-like pads 5 a made of a translucent material as an input operation element. Here, as an example, a total of 16 pads 5a “PAD1 to PAD16” are arranged on the controller C panel, four in the horizontal direction (left and right in the figure) and four in the vertical direction (up and down in the figure). A matrix arranged in parallel is shown. A touch sensor (for example, a piezoelectric sensor) (not shown) is attached to the bottom of each of the plurality of pads 5a, and the ON / OFF operation (striking) of each pad 5a by this sensor and the strength of tapping ( (Operation intensity) can be detected. For each pad 5a, for example, a drum tone such as bass drum, snare drum, rotor, high tom, hi-hat close, hi-hat open, etc. can be arbitrarily assigned. Therefore, from the controller C shown in FIG. 3, it is possible to generate music data that can be played with a maximum of 16 types of drum tones.

  In addition to the pads 5a of “PAD1 to PAD16”, the switches 5b of “SW1” to “SW4” and the “Knob” switch 5c are provided at appropriate positions on the panel of the controller C as shown in the figure. It may be done. In FIG. 3, each of these switches 5b and 5c arranged below the pad has a predetermined function. For example, it has a function for switching tone banks, a function for entering various “setting modes”, a function for exiting various “setting modes”, a function for switching operation modes, a function for editing parameter values, and the like. At least one display 7 (for example, LED) to be described later is incorporated immediately below (or in the vicinity of) each of the switches 5b and 5c.

  The display circuit 6 performs lighting / extinguishing control of the display device 7 (for example, LED) according to the operation of the operation element 5 by the user. As shown in FIG. 3, LEDs 7 having different display colors are arranged immediately below (or in the vicinity of) the plurality of pads 5a (only two are shown here, but two or more may be used). Thus, the display circuit 6 is configured to be able to light the entire pad 5a with at least three display colors by controlling the lighting state / light-off state of each of the two LEDs 7 in combination.

  Specifically, the LED 7 whose display color is red is arranged on one side, and the LED 7 whose display color is green is arranged on the other side. In this case, when only one of them is lit, the pad 5a shines in “red” or “green”, and when both are lit simultaneously, the pad 5a shines in “orange”. Become. In this embodiment, the user refers to the display color when the pad 5a pressed by the user shines, and immediately after operating the velocity value of the music data generated in response to the pressing operation of the pad 5a. (The details will be described later). By illuminating the entire pad 5a, the user does not have to keep an eye on the pad 5a during the music data input operation, so that the velocity value can be easily confirmed. Further, by performing LED control so as to change the display color, the user can easily determine.

  The communication interface (I / F) 8 is connected to, for example, a general-purpose or dedicated communication cable, or a wired or wireless communication network such as a LAN, the Internet, or a telephone line, and the computer is connected via the communication cable or the communication network. It is an interface for transmitting and receiving music data, various signals, and various information with the computer P (see FIG. 1). Such a communication interface 8 may be both wired or wireless and may include both.

  As described above, the user can input drum tone music data to the computer P running the music production software program F by performing a pressing operation such as hitting the pad 5a on the controller C side. It has become. In the present embodiment, the display color of the pad 5a operated by the user is changed according to the velocity value instead of the operation intensity unlike the conventional case, so that the velocity value of the music data input according to the pad operation by the user every time the user operates. So that you can check it right away.

  Therefore, the “pad operation process” for realizing the lighting control of the LED (display device 7) according to the magnitude of the velocity value as described above according to the operation of the pad 5a by the user will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the “pad operation process”. This “pad operation process” is executed by the CPU 1 of the controller C every time an operation by the user on at least one of the plurality of pads 5 a arranged on the controller C is detected.

  In step S1, it is determined whether or not the input mode is set as the device setting. Here, the input mode is a device setting that can input music data to the computer P according to the pad operation by the user. For example, the device is automatically set as an initial mode when the controller C is turned on. . If it is determined that the input mode is not set (NO in step S1), the device is set to a mode other than the input mode, and the function corresponding to the mode is executed (step S14). Examples of modes other than the input mode include “velocity curve change mode” and “bank setting mode”. When the device is set to these modes, a function for realizing each mode is assigned to the pad 5a. In the “velocity curve change mode”, a function for selecting one of a plurality of velocity curves is assigned to each pad 5a (see FIG. 6 described later). In the “bank setting mode”, A function of selecting one of a plurality of tone color banks is assigned to each pad 5a. After the process of step S14, this process ends. As described above, when the input mode is not set, the music data is not transmitted to the computer P.

  On the other hand, when it is determined that the input mode is set (YES in step S1), it is determined whether or not an operation of pressing (hitting) the pad 5a by the user, that is, a pad-on operation has been performed (step S2). When it is determined that the pad-on operation by the user has been performed (YES in step S2), the operation intensity of the pad 5a at the time of the pad-on operation is detected with respect to one or more pads 5a that have been most recently performed by the user. (Step S3). In step S4, a velocity value corresponding to the detected user operation intensity of the pad is determined according to a known velocity curve selected in advance (see FIG. 5). In other words, the user operation intensity is converted into a velocity value. In step S5, note-on data including the determined velocity value relating to the drum timbre previously assigned to the one or more pads 5a most recently subjected to the pad-on operation by the user is transmitted to the computer P (see FIG. 1).

  Here, FIG. 5 shows an example of a velocity curve (velocity information) used for determining (converting) a velocity value corresponding to the user operation intensity of the pad. The velocity curve may be stored in advance in the ROM 2 or the like of the controller C, or the one obtained from the computer P may be stored in the RAM 3 or the like as necessary. Although only 16 types of velocity curves are shown in the example shown in FIG. 5, it goes without saying that more types of velocity curves may be prepared.

  Each velocity curve has “No”, “Name”, and “Function”. “No” is a unique number assigned to each velocity curve. The “name” is given a name or the like that briefly represents the feature of “function” of each velocity curve. These “No” and “Name” are information for individually identifying velocity curves. “Function” is information indicating the correspondence between the user operation intensity and the velocity value (shown here as a graph). In each graph, the horizontal axis indicates the user operation intensity applied to the pad, and the vertical axis indicates the velocity. Represents a value. That is, the velocity curves of “No” 1 to 8 on the left side have a correspondence relationship in which the velocity value changes depending on the magnitude of the user operation intensity, and each of these velocity curves has a velocity corresponding to the change in the user operation intensity. The change mode of the value is different. On the other hand, the velocity curves of “No” 9 to 16 on the right side have a corresponding relationship in which the velocity values are constant regardless of the magnitude of the user operation intensity, and the velocity values that are constant in each of these velocity curves are respectively They are different (in this example, the values 16, 32, 48, 64, 80, 96, 112, 127).

  Returning to the description of FIG. 4, in step S <b> 6, it is determined whether or not the determined velocity value is greater than or equal to a preset first set value (first threshold). If it is determined that the velocity value is greater than or equal to the first set value (YES in step S6), one of the LEDs (for example, the lighting color is set) immediately below the pad on which the pad-on operation was most recently performed by the user is determined. The red LED 7 (see FIG. 3) is turned on (step S7). On the other hand, when it is determined that the velocity value is not greater than or equal to the first set value (NO in step S6), the LED 7 whose lighting color is red is not turned on but remains turned off (step S8).

  In step S9, it is determined whether or not the determined velocity value is equal to or less than a preset second setting value (second threshold value, which is a value having a certain amount of width than the first threshold value). judge. If it is determined that the velocity value is less than or equal to the second set value (YES in step S9), one of the LEDs provided immediately below the pad on which the pad-on operation was most recently performed by the user (in this case, the lighting color) The green LED 7 (see FIG. 3) is turned on (step S10). On the other hand, when it is determined that the velocity value is not less than or equal to the second set value (NO in step S9), the LED 7 whose lighting color is green is not turned on but remains turned off (step S11). Thereafter, this process is terminated.

  Here, specific examples of the first set value and the second set value are shown. For example, the first set value is a velocity value “43”, and the second set value is a velocity value “84”. If so, when the velocity value corresponding to the user operation intensity of the pad is “1” to “42”, the red LED 7 is not lit because it is not equal to or greater than the first set value “43”. Since the second set value is “84” or less, the green LED 7 is turned on. That is, the pad glows green.

  Further, when the velocity value corresponding to the user operation intensity of the pad is “43” to “84”, the red LED 7 is turned on because it is equal to or greater than the first set value “43”, and the second set value is set. Since it is “84” or less, the green LED 7 is also turned on. That is, the pad shines orange with a mixture of red and green. Further, when the velocity value corresponding to the user operation intensity of the pad is “85” to “127”, the red LED 7 is lit while the second set value is “43” or more, while the second LED 2 is turned on. Since it is not less than the set value “84”, the green LED 7 is not lit. That is, the pad glows red.

  If it is determined in step S2 that the user has performed a pad-off operation instead of a pad-on operation (NO in step S2), a drum tone that has been assigned to the pad in advance for a pad that has been most recently pad-off operated by the user. Is transmitted to the computer P (see FIG. 1) (step S12). In step S13, all the LEDs 7 provided immediately below the pad that was most recently subjected to the pad-off operation by the user are turned off (step S13). Thereafter, this process is terminated.

  As described above, the pad is lit with a different color according to the velocity value determined according to the user operation intensity of the pad. Since the lighting color of these pads changes immediately according to the pad-on operation by the user, this allows the user to immediately confirm the magnitude of the velocity value determined according to the operation intensity of the pad. Become. As in the present embodiment, the display mode of the display (LED) is changed and controlled according to the magnitude of the velocity value, not according to the user operation intensity to the conventional pad, as described below. It is particularly important from a point of view.

  When the user inputs drum tone music data from the controller C, the user can change the velocity curve in advance (see step S14). Here, when the velocity curves of “No” 9 to 16 shown in FIG. 5 are changed, the velocity values of these velocity curves are constant regardless of the magnitude of the user operation intensity, and the operation on the pad is performed. Since the same velocity value can always be output regardless of the strength, the user does not need to pay particular attention to the input velocity value (the same velocity value is set regardless of whether the force is applied strongly or weakly).

  On the other hand, when the velocity curves of “No” 1 to 8 shown in FIG. 5 are changed, the velocity values of these velocity curves change depending on the magnitude of the user operation intensity, and the user operation intensity. Since the velocity value different from that before the change is output even if the values are the same, the user needs to pay particular attention to the input velocity value. However, as described above, in the past, since the user could only estimate the velocity value based on the lighting state of the LED according to the operation intensity of the pad, the user is correct before and after the velocity curve change. It is difficult to guess the velocity value. Therefore, in the present embodiment, the lighting of the LED is controlled not according to the user operation intensity but according to the velocity value in accordance with the processing of steps S6 to S11 described above, and the user confirms the velocity value based on the lighting mode of the LED. To be able to do that.

  As described above, the velocity curve can be selected from any of a number of curves shown in FIG. 5 according to the pad operation of the controller C. Accordingly, the velocity curve changing process will be described next. FIG. 6 is a flowchart showing an embodiment of the velocity curve changing process. This processing is started when the velocity curve change mode is set as the device setting. Specifically, when the “SW2” switch 5b (see FIG. 3) is pressed, the “velocity curve change mode” is set, and while being pressed, the state set to the “velocity curve change mode” is maintained. When the “SW2” switch 5b is released, the “velocity curve change mode” is canceled and the mode returns to the “input mode”.

  In step S21, the LED 7 provided immediately below (or in the vicinity of) the “velocity curve change mode” setting switch SW2 is turned on in order to indicate that it is the velocity curve change mode. Further, a plurality of velocity curves stored in advance are assigned to the pads 5a having the same numbers as the numbers unique to the curves ("No" 1 to 16 shown in FIG. 5). In step S22, at least one of the LEDs 7 provided immediately below (or in the vicinity of) the pad having the same number as the number (any one of “No” 1 to 16) indicating the velocity curve that has been set (selected) at the present time is selected. Light. For example, the red LED 7 is turned on. In step S23, it is determined whether or not the user has performed a pressing operation (pad-on operation) on any of the pads 5a. If it is determined that the user has not performed any pad-on operation on any of the pads 5a (NO in step S23), the process jumps to step S29. On the other hand, if it is determined that the pad-on operation by the user has been performed on any of the pads 5a (YES in step S23), it is specified which pad 5a has been pad-on operated by the user (step S24).

  In step S25, it is determined whether or not the lit pad 5a, that is, the pad 5a for selecting the velocity curve already set at the present time has been operated. If it is determined that the lit pad 5a has been operated (YES in step S25), there is no need to change the velocity curve, and the process jumps to step S29. On the other hand, when it is determined that a pad 5a other than the lit pad has been operated (NO in step S25), the LED 7 of the lit pad 5a is turned off (step S26), while the LED 7 of the operated pad 5a is turned off. Is turned on (step S27). When a velocity curve (see FIG. 5) to which the same unique number as the number of the operated pad is assigned is determined as a velocity value corresponding to the operation intensity applied to the pad 5a by the user (see step S4 in FIG. 4). ) Is changed and set as the velocity curve used for (step S28).

  In step S29, it is determined whether or not an instruction to end the velocity curve change mode has been given. As an instruction to end the velocity curve change mode, for example, there is a mode change operation to the input mode. If it is determined that the instruction to end the velocity curve change mode has not been given (NO in step S29), the process returns to step S23 and the processes in steps S23 to S28 are repeated. On the other hand, if it is determined that an instruction to end the velocity curve change mode has been issued (YES in step S29), the LED 7 of the pad 5a that is lit, that is, the pad 5a for selecting the currently set velocity curve is displayed. In addition to turning off the light (step S30), the LED 7 of the “velocity curve change mode” setting switch for presenting the velocity curve change mode is turned off (step S31). Then, the velocity curve changing mode is ended, and processing corresponding to an operation made as an instruction to end the velocity curve changing mode, for example, processing for shifting to the input mode according to the mode changing operation, is executed (step S32). ).

  As described above, in the velocity curve changing mode, the pad 5a that has been an operator for inputting music data is temporarily assigned as an operator for selecting a velocity curve, and the user operates the pad 5a to operate the velocity. The curve can be changed. According to this, since the velocity curve can be changed in the same operation manner as when the music data is input, there is an advantage that the operation is easy to understand for the user. Further, since there is no need to provide a separate operator for selecting a velocity curve, this contributes to downsizing and cost reduction of the controller C.

  As mentioned above, although an example of embodiment was demonstrated based on drawing, this invention is not limited to this, It cannot be overemphasized that various embodiment is possible. For example, in the above-described embodiment, the timbre that can be assigned to each pad 5a is a drum timbre, but is not limited thereto, and other percussion instrument timbres such as marimba and timpani may be assigned. Further, instead of these percussion instrument sounds, for example, normal normal timbres such as piano timbres and guitar timbres may be used. When the normal tone color is assigned, it is preferable to control the display mode of the display device in accordance with the volume change (aftertouch, horizontal touch) while the pad is pressed.

Note that the operator for inputting music data is not limited to a pad, and may be a keyboard or a button. Moreover, not only a physical operation element but a virtual operation element displayed on a touch panel display may be used. However, in that case, it goes without saying that the touch panel type display can not only detect that the screen is touched but also can detect the strength when the screen is pressed.
In addition, although LED7 arrange | positioned directly under (or the vicinity) of the pad was mentioned as an example as an indicator which performs lighting control according to a velocity value, it is not restricted to this, and a velocity value like a level meter is prepared on a display prepared separately. It is also possible to perform continuous display according to the above. Further, the lighting control of the LED 7 according to the velocity value is not limited to the three stages of red, green, and orange. Furthermore, it may be brightness instead of display color, or the number of simultaneously lighting three or more LEDs 7 or the like.
