DETAILED DESCRIPTION OF THE INVENTION

[0010] Preferred embodiments will now be described with reference to the accompanying drawings. An overview of a sound source device 1 according to this embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing the external appearance of the sound source device 1. The sound source device 1 is an electronic device that outputs (emits) musical tones based on performance information received from an electronic percussion instrument such as an electronic drum 30. The sound source device 1 is provided with an LCD 2 that displays various setting values ​​and a striking surface display Gd1, which will be described later with reference to FIG. 2 and subsequent figures.

[0011] An electronic drum 30 and an electronic cymbal 40 are connected to the sound source device 1. The electronic drum 30 is an electronic percussion instrument that transmits performance information corresponding to strikes on the striking surface by the user H to the sound source device 1. The electronic drum 30 has a striking surface that is circular when viewed from above, and the performance information transmitted from the electronic drum 30 includes strike information on the striking surface (head) or rim, strike position and velocity which are the position where the striking surface is struck when it is struck, the position and pressure when the striking surface is pressed, and the velocity when the rim is struck, but other information related to strikes on the electronic drum 30 may also be transmitted.

[0012] The electronic cymbal 40 is an electronic percussion instrument that transmits performance information to the sound source device 1 in response to a strike on the striking surface by the user H. In this embodiment, an electronic hi-hat that imitates a hi-hat is used as the electronic cymbal 40, but the present invention is not limited to this, and an electronic cymbal that imitates another cymbal, such as a ride cymbal, may also be used as the electronic cymbal 40.

[0013] The electronic cymbal 40 also has a circular striking surface when viewed from above, and the performance information transmitted from the electronic cymbal 40 includes striking information on the striking surface or bell, the striking position and velocity where the striking surface is struck, the pressing position when the periphery of the striking surface is pinched and pressed by user H to create a choke, and the velocity when the bell is struck, but other information relating to striking the electronic cymbal 40 may also be transmitted.

[0014] In this embodiment, the electronic drum 30 and electronic cymbal 40 are configured as so-called "digital pads" that can calculate performance information including the striking position by themselves. A known method, such as the method disclosed in Japanese Patent Application Laid-Open No. 2018-36641, is used to detect the striking position of the digital pad. In this embodiment, the sound source device 1, the electronic drum 30, and the electronic cymbal 40 are connected by wire, but this is not limiting and they may also be connected wirelessly.

[0015] Performance information based on the strikes made by the user H on the electronic drum 30 or the like is transmitted to the sound source device 1, and the sound source device 1 generates and sounds musical tones based on the performance information received from the electronic drum 30 or the like. At this time, the user H, who is a beginner and has inexperienced playing skills, may want to know which part of the electronic drum 30 or the like has actually been struck, in addition to the musical tones being produced.

[0016] Therefore, in this embodiment, the LCD 2 displays a striking surface display Gd1, etc. that imitates the striking surface of the struck electronic drum 30, etc., and a striking position display HP based on the striking position on the striking surface display Gd1, etc., so that the user H can specifically grasp the position where the electronic drum 30, etc. was struck. The striking surface display Gd1, etc. will be described with reference to FIGS. 2 to 5.

[0017] 2(a) is a diagram showing the LCD 2 when a striking surface display Gd1 for the electronic drum 30 is displayed. When the electronic drum 30 is struck, the LCD 2 displays a striking surface display Gd1 that resembles the striking surface of the electronic drum 30. The striking surface display Gd1 is composed of an image that represents the striking surface of the electronic drum 30 in two dimensions (i.e., on a plane), and its outer shape is formed in a circular shape, just like the striking surface of the electronic drum 30.

[0018] The striking surface display Gd1 includes a center area display Ca, a rim area display Ra, and radial display HL. The center area display Ca is a circular display area displayed in the center of the striking surface display Gd1. In the electronic drum 30 of this embodiment, when the center of the striking surface and a certain area around the center of the striking surface are struck, it is determined that the center of the striking surface has been struck.

[0019] Therefore, a central area display Ca is displayed in an area of ​​the striking surface display Gd1 that corresponds to a certain range where it is determined that the center of the striking surface of the electronic drum 30 has been struck. This central area display Ca allows the user H to grasp the area where it is determined that the center of the striking surface of the electronic drum 30 has been struck.

[0020] In this embodiment, since the above-mentioned fixed range on the electronic drum 30 is formed in a circular shape, the central area display Ca of the striking surface display Gd1 is also formed in a circular shape. However, this is not limited to this. For example, if the above-mentioned fixed range is formed in a rectangular shape, the central area display Ca may also be formed in a rectangular shape, and the shape of the central area display Ca may be changed arbitrarily to match the shape of the above-mentioned fixed range.

[0021] The rim area display Ra is a display area provided along the outer periphery of the striking surface display Gd1, and is formed based on the area of ​​the rim of the electronic drum 30.

[0022] The radial indicators HL are linear display parts that radiate from the center area indicator Ca to the rim area indicator Ra. In this embodiment, eight radial indicators HL are provided on the striking surface indicator Gd1. When an area excluding the center and rim of the striking surface of the electronic drum 30 is struck, a striking position indicator HP based on the struck position is displayed on the striking surface indicator Gd1, and that striking position indicator HP is displayed on the radial indicator HL that is closest to the received striking position.

[0023] The number of radial indicators HL is not limited to eight, and for example, if the detection accuracy of the striking position of the electronic drum 30 is high, the number of radial indicators HL may be more than eight, and if the detection accuracy of the striking position of the electronic drum 30 is low, the number of radial indicators HL may be less than eight.

[0024] Furthermore, as shown in FIG. 2(a), the radial indicators HL are not limited to being evenly arranged on the striking surface display Gd1. For example, if the striking surface of the electronic drum 30 contains a mixture of positions where the strike detection accuracy is high and positions where the strike detection accuracy is low, the density of the radial indicators HL (i.e., the number of radial indicators HL per unit area) may be increased in the areas of the striking surface display Gd1 corresponding to the positions where the strike detection accuracy is high, and the density of the radial indicators HL may be decreased in the areas of the striking surface display Gd1 corresponding to the positions where the strike detection accuracy is low.

[0025] Here, we will explain the striking position display HP displayed on the radial display HL. The striking position display HP is a black circle-shaped display part that is displayed at the corresponding position on the striking surface display Gd1 when the area of ​​the electronic drum 30 excluding the center and rim of the striking surface is struck. Since the striking surface display Gd1 is composed of an image that represents the striking surface of the electronic drum 30 in two dimensions, the striking position display HP is also positioned in a two-dimensional position (a position on a plane) on the striking surface display Gd1.

[0026] In this way, the striking surface display Gd1, which is configured as a two-dimensional image that resembles the striking surface of the electronic drum 30, is displayed, and the striking position display HP, which is positioned in a two-dimensional position based on the striking position received from the electronic drum 30, is displayed on the striking surface display Gd1. In other words, by displaying the striking surface display Gd1 that resembles the striking surface of the electronic drum 30 expressed in a plane and the striking position display HP that is positioned in a two-dimensional position on the striking surface display Gd1, the user H can more specifically grasp the position where the electronic drum 30 was struck.

[0027] Furthermore, eight radial indicators HL are displayed on the striking surface display Gd1, and the striking position indicator HP is displayed on the radial indicator HL that is closest to the striking position received from the electronic drum 30. In other words, because the display of the striking position indicator HP is limited to eight radial indicators HL from the entire striking surface display Gd1, the processing load on the sound source device 1 for displaying the striking position indicator HP is reduced, and the striking position indicator HP can be displayed quickly.

[0028] Next, with reference to Figures 2(b) to 2(e), we will explain the striking surface display Gd1 when various parts of the electronic drum 30 are struck. Figure 2(b) is a diagram showing the striking surface display Gd1 when the center of the striking surface of the electronic drum 30 is struck, Figure 2(c) is a diagram showing the striking surface display Gd1 when the rim of the electronic drum 30 is struck, and Figures 2(d) and 2(e) are diagrams showing the striking surface display Gd1 when the electronic drum 30 is hit with an open rim shot.

[0029] As shown in Figure 2(b), when the center of the striking surface of the electronic drum 30 or the aforementioned certain range around the center of the striking surface of the electronic drum 30 is struck, the display mode (e.g., color) of the central area display Ca in the striking surface display Gd1 changes. Note that in the figure, when the center of the striking surface of the electronic drum 30 or the aforementioned certain range is not struck, the central area display Ca is displayed in white as shown in Figure 2(a), and when the center of the striking surface of the electronic drum 30 or the aforementioned certain range is struck, the central area display Ca is displayed in a shaded pattern as shown in Figure 2(b).

[0030] In this way, the change in the display mode of the central area display Ca in the striking surface display Gd1 indicates whether the center of the striking surface of the electronic drum 30 or the above-mentioned certain range has been struck, and so the change in the display mode of the central area display Ca can be said to be a “strike position display.” By comparing the user H’s own strike near the center of the striking surface of the electronic drum 30 with the accompanying change in the display mode of the central area display Ca, the user H can more specifically grasp whether the center of the striking surface or the above-mentioned certain range is where it is determined that the center of the striking surface of the electronic drum 30 has been struck.

[0031] The change in the display mode of the central area display Ca is not limited to the above, and other changes in the display mode may be used, such as displaying the central area display Ca in black when the center of the striking surface of the electronic drum 30 or the above-mentioned certain range is not struck, and displaying the central area display Ca in yellow when the center of the striking surface of the electronic drum 30 or the above-mentioned certain range is struck.

[0032] Next, referring to Fig. 2(c), the striking surface display Gd1 when the rim of the electronic drum 30 is struck will be described. As shown in Fig. 2(c), when the rim of the electronic drum 30 is struck, the display mode (e.g., color) of the rim area display Ra in the striking surface display Gd1 changes. In the figure, when the rim of the electronic drum 30 is not struck, the rim area display Ra is displayed in white, as shown in Fig. 2(a), and when the rim of the electronic drum 30 is struck, the rim area display Ra is displayed in a shaded pattern, as shown in Fig. 2(c).

[0033] In this way, when the rim of the electronic drum 30 is struck, the display mode of the rim area display Ra changes, allowing the user H to easily understand that the rim of the electronic drum 30 has been struck. Note that the change in the display mode of the rim area display Ra is not limited to the above, and other changes in the display mode may also be used, such as displaying the rim area display Ra in light blue when the rim of the electronic drum 30 is not struck, and displaying the rim area display Ra in red when the rim of the electronic drum 30 is struck.

[0034] Next, referring to Figures 2(d) and 2(e), the striking surface display Gd1 when an open rim shot is performed on the electronic drum 30 will be described. As shown in Figure 2(d), when an open rim shot is performed in which the center of the striking surface of the electronic drum 30 or the above-mentioned certain range is struck simultaneously with the rim, the display modes of the center area display Ca and the rim area display Ra are simultaneously changed. Also, as shown in Figure 2(e), when an open rim shot is performed in which the rim is struck simultaneously with the center of the striking surface of the electronic drum 30 or a position outside the above-mentioned certain range, the striking position display HP is displayed at the position on the striking surface display Gd1 corresponding to that position outside the range, and the display mode of the rim area display Ra is changed.

[0035] In this way, when an open rim shot is performed on the electronic drum 30, the display mode of the rim area display Ra changes, and the striking position display HP corresponding to the position where the electronic drum 30 was struck or the display mode of the central area display Ca changes, so that the user H can easily understand that an open rim shot has been performed on the electronic drum 30 and which part of the striking surface has been struck together with the rim by the open rim shot.

[0036] Next, the striking surface display Gd2 for the electronic cymbal 40 will be described with reference to Figures 3(a) to (c). Figure 3(a) is a diagram showing the LCD2 when the striking surface display Gd2 for the electronic cymbal 40 is displayed. When the electronic cymbal 40 is struck, the striking surface display Gd2 that imitates the striking surface of the electronic cymbal 40 is displayed on the LCD2. The striking surface display Gd2 is composed of an image that represents the striking surface of the electronic cymbal 40 in two dimensions. The striking surface display Gd2 has a semicircular shape that is the lower half of the striking surface of the electronic cymbal 40 when viewed from above.

[0037] The striking surface display Gd2 includes a bell display Ba, an outer periphery display Ta arranged along the outer periphery of the striking surface display Gd2, and radial displays HL. The bell display Ba is a circular display area displayed in the center of the striking surface display Gd2. The bell display Ba is formed in a circular shape corresponding to the bell of the electronic cymbal 40.

[0038] The radial indicators HL are linear display parts formed radially from the bell indicator Ba toward the outer periphery indicator Ta. In this embodiment, seven radial indicators HL are provided on the striking surface indicator Gd2. The number of radial indicators HL on the striking surface indicator Gd2 may be seven or more or fewer depending on factors such as the detection accuracy of the striking position of the electronic cymbal 40.

[0039] When the electronic cymbal 40 is struck on an area excluding the bell and outer periphery, the strike position display HP is displayed on the radial display HL closest to the received strike position, similar to the striking surface display Gd1 described above in Figure 2. The strike position display HP on the striking surface display Gd2 is also positioned at a two-dimensional position (coordinates) on the striking surface display Gd2.

[0040] In this way, the striking surface display Gd2, which is composed of a two-dimensional image that resembles the striking surface of the electronic cymbal 40, is displayed, and the striking position display HP, which is positioned in a two-dimensional position based on the striking position received from the electronic cymbal 40, is displayed on the striking surface display Gd1. As with the striking surface display Gd1 for the electronic drum 30 described above, this allows the user H to more specifically grasp the position where the electronic cymbal 40 was struck.

[0041] Meanwhile, the outline of the striking surface display Gd1 corresponding to the electronic drum 30 is formed in a circular shape similar to the shape of the striking surface of the electronic drum 30 when viewed from above, whereas the outline of the striking surface display Gd2 corresponding to the electronic cymbal 40 is formed in a semicircular shape, which is the lower half of the shape (circular shape) of the striking surface when viewed from above.

[0042] This is because strikes can be detected over the entire striking surface of the electronic drum 30, whereas strikes can only be detected over the lower half of the striking surface of the electronic cymbal 40 when viewed from above. In this way, the striking surface display Gd2 is formed in a shape that corresponds to the position on the striking surface of the electronic cymbal 40 where strikes can be detected, so that the user H can easily grasp the area on the striking surface of the electronic cymbal 40 where strikes can be detected.

[0043] Next, with reference to Figures 3(b) and 3(c), we will explain the striking surface display Gd2 when the bell of the electronic cymbal 40 is struck and when the outer periphery of the electronic cymbal 40 is choked. Figure 3(b) is a diagram showing the striking surface display Gd2 when the bell of the electronic cymbal 40 is struck, and Figure 3(c) is a diagram showing the striking surface display Gd2 when the outer periphery of the electronic cymbal 40 is choked.

[0044] As shown in Fig. 3(b), when the bell of the electronic cymbal 40 is struck, the display mode (for example, color) of the bell display Ba changes. In the figure, when the bell of the electronic cymbal 40 is not struck, the bell display Ba is displayed in white as shown in Fig. 3(a), and when the bell of the electronic cymbal 40 is struck, the bell display Ba is displayed in a shaded pattern as shown in Fig. 3(b).

[0045] In this way, when the bell of the electronic cymbal 40 is struck, the display mode of the bell display Ba changes, allowing the user H to easily understand that the bell of the electronic cymbal 40 has been struck. Note that the change in the display mode of the bell display Ba is not limited to the above, and other changes in the display mode may be used, such as displaying the bell display Ba in green when the bell of the electronic cymbal 40 has not been struck, and displaying the bell display Ba in red when the bell of the electronic cymbal 40 has been struck.

[0046] 3(c), when the outer periphery of the electronic cymbal 40 is pinched and choked by the user H, the display mode of the outer periphery display Ta of the striking surface display Gd2 is changed, and a choked display CP, which is a black circle display part, is displayed in the outer periphery display Ta at a position corresponding to the pressed position where the electronic cymbal 40 was pressed with the choked edge. This allows the user H to easily understand that the outer periphery of the electronic cymbal 40 has been choked and which part of the outer periphery has been pinched.

[0047] In this way, when the electronic drum 30 is struck, the striking surface display Gd1 of Fig. 2 is displayed on the LCD 2, and when the electronic cymbal 40 is struck, the striking surface display Gd2 of Fig. 3(a) to (c) is displayed on the LCD 2. In this embodiment, the striking surface display Gd1 or Gd2 displayed on the LCD 2 is switched based on the "position type" assigned to the struck electronic drum 30 or electronic cymbal 40, respectively. The position types will be explained with reference to Figs. 3(d) and 3(e).

[0048] Fig. 3(d) is a diagram explaining a method for detecting the striking position of the electronic drum 30, and Fig. 3(e) is a diagram explaining a method for detecting the striking position of the electronic cymbal 40. The electronic drum 30 and electronic cymbal 40 in this embodiment are configured as so-called "digital pads" that can acquire performance information including striking position by themselves, and each uses a different method for detecting striking position.

[0049] As shown in FIG. 3(d), the electronic drum 30 detects the striking position by combining the position Pos_CU on the center-to-outer periphery axis connecting the center Ct to the outer periphery Ut and the angle Ang with the center Ct as the center.

[0050] On the other hand, in the electronic cymbal 40, as shown in Figure 3(e), the striking position is detected by a combination of the position Pos_CU on the center-periphery axis connecting the center Ct to the outer periphery Ut, and the position Pos_LR on the left-right axis connecting the top end Rt of the right half of the striking surface and the top end Lt of the left half of the striking surface.

[0051] Hereinafter, the method for detecting a striking position in such an electronic percussion instrument will be referred to as the "position type." In this embodiment, a corresponding display part such as striking surface display Gd1 or Gd2 is assigned to each position type. Specifically, the position types "center-outer periphery axis" and "angle" (FIG. 3(d)) are assigned display parts (FIG. 2(a)) that are used in conjunction with striking surface display Gd1, such as striking surface display Ba, while the position types "center-outer periphery axis" and "left-right axis" are assigned display parts (FIG. 3(a)) that are used in conjunction with striking surface display Gd2.

[0052] Furthermore, the user H assigns a position type to each electronic percussion instrument connected to the sound source device 1. For example, the electronic drum 30 is assigned the position types: "center-outer periphery axis" and "angle", and the electronic cymbal 40 is assigned the position types: "center-outer periphery axis" and "left-right axis".

[0053] Then, the position type of the struck electronic percussion instrument among those connected to the sound source device 1 is acquired, and display parts such as striking surface displays Gd1, Gd2, etc. corresponding to the acquired position type are acquired and displayed on the LCD 2. As a result, when the electronic drum 30 is struck, the striking surface display Gd1 as shown in Fig. 2(a) is displayed on the LCD 2 of the sound source device 1, and when the electronic cymbal 40 is struck, the striking surface display Gd2 as shown in Fig. 3(a) is displayed on the LCD 2 of the sound source device 1.

[0054] The sound source device 1 is configured to be connectable not only to digital pads such as the electronic drum 30 and electronic cymbal 40, but also to analog pads that transmit only strike waveforms, which are waveforms based on the output values ​​of sensors that detect strikes, and produces musical tones based on the received strike waveforms. Since the strike position that can be obtained from the strike waveform received from an analog pad is only the "center-outer periphery axis" shown above, the position type of the analog pad is "center-outer periphery axis." Here, with reference to Figure 4, we will explain the striking surface display Gd3 that is displayed on the LCD 2 when an analog pad is struck.

[0055] 4(a) is a diagram showing the LCD 2 when the striking surface display Gd3 for an analog pad is displayed. When an analog pad is struck, the striking surface display Gd3 is displayed on the LCD 2. The striking surface display Gd3 includes a central area display Ca, a rim area display Ra, and radial displays HL, similar to the striking surface display Gd1 shown in FIG. 2.

[0056] Of these, the radial display HL is different from the striking surface displays Gd1 and Gd2 shown in Figures 2 and 3 above, in that only one line is displayed. This is because the analog pad's position type is "center-periphery axis," and it can only detect striking positions in one axis direction. When an area of ​​the analog pad excluding the center and rim of the striking surface is struck, the striking position display HP based on that striking position is displayed on the radial display HL.

[0057] Next, the striking surface display Gd3 when each part of the analog pad is struck will be explained with reference to Figures 4(b) to 4(e). Figure 4(b) shows the striking surface display Gd3 when the center of the striking surface of the analog pad is struck, Figure 4(c) shows the striking surface display Gd3 when the rim of the analog pad is struck, and Figures 4(d) and 4(e) show the striking surface display Gd3 when the analog pad is struck with an open rim shot.

[0058] As shown in Figure 4(b), when the center of the striking surface of the analog pad or a certain area around it is struck, the display mode (e.g., color) of the center area display Ca changes, and as shown in Figure 4(c), when the rim of the analog pad is struck, the display mode of the rim area display Ra changes. Also, as shown in Figures 4(d) and 4(e), when the analog pad is struck with an open rim shot, the display mode of the rim area display Ra changes, and the electronic drum 30 displays a strike position display HP corresponding to the position where the electronic drum 30 was struck, or the display mode of the center area display Ca changes.

[0059] In this way, the striking surface display Gd3 for the analog pad is displayed in the same manner as the striking surface display Gd1 for the electronic drum 30 and the striking surface display Gd2 for the electronic cymbal 40. This prevents the user H from feeling uncomfortable between the display content displayed on the LCD 2 when the analog pad and the electronic drum 30 are connected to the sound source device 1 and the display content displayed on the LCD 2 when the analog pad is struck and the display content displayed on the LCD 2 when the electronic drum 30 is struck.

[0060] Next, the functions of the sound source device 1 will be described with reference to Fig. 5. Fig. 5 is a functional block diagram of the sound source device 1. As shown in Fig. 5, the sound source device 1 has a striking surface display means 500 and a striking position display means 501.

[0061] The striking surface display means 500 is means for displaying striking surface displays Gd1, Gd2 that are composed of at least two-dimensional images that resemble the striking surface of an electronic percussion instrument 550, such as the electronic drum 30 or electronic cymbal 40, and is realized by the CPU 10, which will be described later with reference to FIG. 6(a). The striking position display means 501 is means for displaying, on the striking surface displays Gd1, Gd2 displayed by the striking surface display means 500, striking position displays HP that are arranged in at least two-dimensional positions based on the striking position acquired from the electronic percussion instrument 550. The striking position display means 501 is realized by the CPU 10.

[0062] That is, striking surface displays Gd1, Gd2 composed of two-dimensional images that resemble the electronic percussion instrument 550 are displayed, and striking position displays HP, which are positioned in two dimensions based on the striking position acquired from the electronic percussion instrument 550, are displayed in corresponding positions on the striking surface displays Gd1, Gd2. By displaying striking surface displays Gd1, Gd2 composed of at least two-dimensional images, for example, striking surface displays Gd1, Gd2 expressed in a plane, and striking position displays HP, which are positioned in at least two-dimensional positions on the striking surface displays Gd1, Gd2, user H can more specifically grasp the positions where the electronic percussion instrument 550 was struck.

[0063] Next, the electrical configuration of the sound source device 1 will be described with reference to Fig. 6. Fig. 6(a) is a block diagram showing the electrical configuration of the sound source device 1. The sound source device 1 has a CPU 10, a flash ROM 11, a RAM 12, the LCD 2 described above, an external input / output device 13, a sound source 14, and a DSP (Digital Signal Processor) 15, which are all connected via a bus line 16. A DAC (Digital Analog Converter) 17 is connected to the DSP 15, an amplifier 18 is connected to the DAC 17, and a speaker 19 is connected to the amplifier 18.

[0064] The CPU 10 is a computing device that controls each unit connected via a bus line 16. The flash ROM 11 is a rewritable nonvolatile memory that stores a control program 11a, a strike display table 11b, and an instrument information table 11c. When the control program 11a is executed by the CPU 10, the main processing of Fig. 7 is executed. The strike display table 11b and the instrument information table 11c will be described with reference to Figs. 6(b) and 6(c).

[0065] 6(b) is a diagram showing a schematic diagram of the striking display table 11b. The striking display table 11b stores display data related to the display of the striking surface display Gd1 and the like displayed for each of the above-mentioned position types. For example, the position types "center-outer periphery axis" and "angle" (i.e., in the case of the electronic drum 30) are associated with the striking surface display Gd1, center area display Ca, and rim area display Ra as display data.

[0066] The position type: "center-outer periphery axis" and "left-right axis" (i.e., in the case of an electronic cymbal 40) are stored in association with the striking surface display Gd2, bell display Ba, and outer periphery display Ta as display data. The position type: "center-outer periphery axis" (i.e., in the case of an analog pad) is stored in association with the striking surface display Gd3, center area display Ca, and rim area display Ra.

[0067] 6(c) is a diagram schematically illustrating the instrument information table 11c. The instrument information table 11c stores a position type for each electronic percussion instrument connected to the sound source device 1. For example, the position types "center-outer periphery axis" and "angle" are stored for the electronic drum 30, and the position types "center-outer periphery axis" and "left-right axis" are stored for the electronic cymbal 40. The instrument information table 11c stores combinations of electronic percussion instruments and position types input by the user H via an input device (not shown) provided on the sound source device 1.

[0068] Among the electronic percussion instruments connected to the sound source device 1, the position type of the struck electronic percussion instrument is obtained from the instrument information table 11c, display data corresponding to the position type is obtained from the strike display table 11b, and the striking surface display Gd1 etc. is displayed on the LCD 2 using the obtained display data.

[0069] Returning to Figure 6(a), the RAM 12 is a memory that stores various types of work data, flags, etc. in a rewritable manner when the CPU 10 executes programs such as the control program 11a. The external input / output device 13 is a device that inputs and outputs information from connected external devices. Electronic percussion instruments such as an electronic drum 30 and an electronic cymbal 40 are connected to the external input / output device 13, and the external input / output device 13 receives performance information from the digital pad electronic percussion instruments and strike waveforms from the analog pad electronic percussion instruments.

[0070] In this embodiment, USB (registered trademark) is used as the communication standard for the external input / output device 13, but the external input / output device 13 may be configured to use another communication standard, or may be configured to input and output information from external devices via wireless communication.

[0071] The sound source 14 is a device that outputs waveform data corresponding to performance information input from the CPU 10. The DSP 15 is a calculation device that processes the waveform data input from the sound source 14. The DAC 17 is a conversion device that converts the waveform data input from the DSP 15 into analog waveform data. The amplifier 18 is an amplification device that amplifies the analog waveform data output from the DAC 17 with a predetermined gain. The speaker 19 is an output device that emits (outputs) the analog waveform data amplified by the amplifier 18 as musical tones.

[0072] Next, the processing executed by the CPU 10 of the sound source device 1 will be described with reference to Fig. 7. Fig. 7 is a flowchart of the percussion processing. The percussion processing is an event processing executed when performance information or a percussion waveform is received from an electronic percussion instrument via the external input / output device 13 after the sound source device 1 is powered on.

[0073] The striking process first acquires the striking position from performance information received from a digital pad such as the electronic drum 30 or electronic cymbal 40 of an electronic percussion instrument (S1). The striking position is then calculated from a striking waveform received from an analog pad of the electronic percussion instrument (S2). The method for calculating the striking position from the striking waveform in the S2 process is a known method, such as the method disclosed in Japanese Patent Application Laid-Open No. 2021-105702. In this embodiment, the S1 process and the S2 process are executed in parallel.

[0074] After the processes of S1 and S2, the position type corresponding to the electronic percussion instrument whose striking position was acquired or calculated in the processes of S1 and S2 is acquired from the instrument information table 11c (see FIG. 6(c)) (S3). Specifically, of the electronic percussion instruments connected to the external input / output device 13, the electronic percussion instrument whose striking position was acquired or calculated in the processes of S1 and S2 is identified, and the position type corresponding to the identified electronic percussion instrument is acquired from the instrument information table 11c.

[0075] After the processing of S3, the display data corresponding to the position type obtained in the processing of S5 is obtained from the impact display table 11b (see Figure 6(b)) (S4), and it is confirmed whether the display data being displayed on LCD2 is different from the display data obtained in the processing of S4 (S5).

[0076] If it is determined in the process of S5 that the currently displayed display data is different from the display data acquired in the process of S4 (S5: Yes), the currently displayed display data is hidden from the LCD 2 (S6). After the process of S6, the display data acquired in the process of S4 is displayed on the LCD 2 (S7). As a result, the striking surface display Gd1 etc. corresponding to the electronic percussion instrument struck last time is hidden, and the striking surface display Gd1 etc. corresponding to the electronic percussion instrument struck this time is newly displayed. On the other hand, if it is determined in the process of S5 that the currently displayed display data is the same as the display data acquired in the process of S4 (S4: No), the processes of S6 and S7 are skipped.

[0077] After the processes of S5 and S7, the impact position acquired or calculated in the processes of S1 and S2 is converted to a position for display (S8). Specifically, the impact position acquired or calculated in the processes of S1 and S2 is converted so that the impact position is placed at a corresponding position on the striking surface display Gd1, etc. At this time, the impact position is moved so that the impact position is located on the closest radial display HL of the striking surface display Gd1, etc.

[0078] Furthermore, since the position of the center-periphery axis among the impact positions acquired or calculated in the processes of S1 and S2 is expressed in 128 stages from 0 to 127, this impact position is converted into 8 stages from 0 to 7. As a result, the positions at which the impact position display HP is displayed on the radial display HL are reduced from 128 to 8, so the processing load of the sound source device 1 for displaying the impact position display HP is reduced and the impact position display HP can be displayed quickly.

[0079] After the processing of S8, the display of the striking position display HP is performed based on the striking position converted in the processing of S8, and the display modes of the central area display Ca and the rim area display Ra in the striking surface displays Gd1 and Gd3 are changed, and the display modes of the bell display Ba and the outer periphery display Ta in the striking surface display Gd2 are also changed (S9).

[0080] After the process of S9, other processes of the sound source device 1 are executed (S10). The other processes in S10 include generating musical tones based on the received performance information or percussion waveform, and outputting the generated musical tones. After the process of S10, the percussion process ends.

[0081] The above has been explained based on the above embodiment, but it can be easily imagined that various improvements and modifications are possible.

[0082] In the above embodiment, Figures 2(b) to (e) show the striking surface display Gd1 when the rim of the electronic drum 30 is struck or when the electronic drum 30 is subjected to an open rim shot. However, in addition to these, the striking surface display Gd1 may also show a display when the electronic drum 30 is subjected to a closed rim shot.

[0083] 8(a), together with the striking position display HP, a pressing display PP may be displayed at a position on the striking surface display Gd10 corresponding to the position where the striking surface of the electronic drum 30 was pressed by the closed rim shot. This striking surface display Gd10 allows the user H to easily understand that the electronic drum 30 was hit with a closed rim shot, and which part of the striking surface was struck and pressed at that time.

[0084] In the above embodiment, the chalk display CP is displayed as a black circle in the striking surface display Gd2 of Fig. 3(c), but this is not limited to this. For example, instead of the chalk display CP, a chalk display HD resembling a human hand may be displayed, as shown in the striking surface display Gd10 of Fig. 8(a). This allows the user H to more intuitively understand that the electronic cymbal 40 has been choked.

[0085] In the above embodiment, the striking surface displays Gd1-Gd3 displayed on the LCD 2 are only those corresponding to the electronic percussion instruments that were actually struck, but this is not limited to this, and striking surface displays Gd1-Gd3 corresponding to all of the electronic percussion instruments connected to the sound source device 1 may be displayed simultaneously. For example, as shown in FIG. 8(c), if an electronic drum 30 and an electronic cymbal 40 are connected to the sound source device 1, striking surface displays Gd1 and Gd2 may be displayed simultaneously on the LCD 2. This allows user H to see at a glance what electronic percussion instruments are connected to the sound source device 1.

[0086] Furthermore, a predetermined striking surface display Gd1 to Gd3 may be displayed on the LCD 2 at all times, regardless of whether or not an electronic percussion instrument connected to the sound source device 1 is struck. In this case, the striking surface display Gd1 to Gd3 designated in advance by the user H may be displayed on the LCD 2 at all times.

[0087] 3(a) to 3(c) are formed in a semicircular shape to match the area of ​​the electronic cymbal 40 where strikes can be detected, but this is not limited to this. The striking surface display Gd2 may be formed in a circular shape similar to the shape of the striking surface of the electronic cymbal 40 when viewed from above. In this case, it is preferable to display in different ways (e.g., colors) the areas of the electronic cymbal 40 where strikes can be detected and the areas where strikes cannot be detected.

[0088] In the above embodiment, the striking surface indicators Gd1 to Gd3 displayed on the LCD 2 are switched based on the position type of the struck electronic percussion instrument, but this is not limited to this. For example, the striking surface indicators Gd1 to Gd3 displayed on the LCD 2 may be switched based on other information that identifies the struck electronic percussion instrument, such as model information of the struck electronic percussion instrument.

[0089] In the above embodiment, the striking surface displays Gd1 to Gd3 are two-dimensional (flat) images, but this is not limiting. For example, the striking surface displays Gd1 to Gd3 may be three-dimensional (stereoscopic) images. Furthermore, the striking position displays HP are also arranged in two dimensions, but this is not limiting and they may also be arranged in three dimensions.

[0090] In the above embodiment, linear radial indicators HL are displayed on the striking surface indicators Gd1 to Gd3, but this is not limited to this. The radial indicators HL may be in other shapes, such as polygonal lines or curved lines. Furthermore, the radial indicators HL may be omitted from the striking surface indicators Gd1 to Gd3.

[0091] In the above embodiment, the electronic drum 30 and the electronic cymbal 40 are used as electronic percussion instruments, but the present invention is not limited to this and other electronic percussion instruments such as an electronic conga may also be used.

[0092] In the above embodiment, the control program 11a is stored in the flash ROM 11 of the sound source device 1 and is configured to run on the sound source device 1. However, this is not necessarily limited to this, and the control program 11a may be configured to run on other computers such as PCs (personal computers), mobile phones, smartphones, tablet devices, or other electronic devices. In this case, the PC, mobile phone, or the like may be provided with a device similar to the external input / output device 13 so that it can be connected to an electronic percussion instrument such as the electronic drum 30.
