Description

[Technical Field]

[0001] The present invention relates to an electronic musical instrument capable of outputting waveform data corresponding to striking strength. [Background technology]

[0002] A typical electronic performance device stores waveform data for specific natural musical instruments, such as acoustic drums and cymbals, when struck, and outputs the stored waveform data when a strike is detected during performance. In this case, for example, when performing a roll (a performance in which the striking surface is struck repeatedly), the same waveform data is simply output repeatedly, which can give the impression that the performance is monotonous.

[0003] Therefore, as disclosed in Patent Document 1, for example, an electronic performance device has been proposed that stores multiple waveform data for each striking strength of a natural musical instrument in advance, and selects and outputs waveform data corresponding to the striking strength during performance according to a predetermined algorithm (random numbers).This conventional technology makes it possible to avoid monotony during roll playing and to electronically create striking sounds that are closer to those of a natural musical instrument.Also, as disclosed in Patent Document 2, for example, a musical sound generating device is disclosed that can obtain a musical sound waveform signal by synthesizing a reference waveform and a residual waveform. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-30474 [Patent Document 2] Japanese Patent Application Publication No. 61-9693 Summary of the Invention [Problem to be solved by the invention]

[0005] However, while the above-mentioned prior art (the prior art disclosed in Patent Document 1) is thought to be able to avoid monotony in performance, it requires a storage means with a large memory area because it is necessary to store multiple waveform data for each striking strength of an acoustic musical instrument in advance. Furthermore, since the waveform data for each striking strength needs to be edited to be optimal for each performance, there are problems in that the editing work requires skill and a huge amount of time.

[0006] Furthermore, in the other prior art (the prior art disclosed in Patent Document 2), even if the residual waveform is changed, for example, by shifting a filter or timing, and added to a reference waveform, the residual waveform does not contain the elements of variation inherent to humans and natural musical instruments, so the expression of the musical tone does not change, and repeated hits sound similar, which is a problem. In particular, in this prior art, it was necessary to generate residual data for each intensity group, such as residual data of a soft sound for a weak hit and residual data of a sharp sound for a strong hit.

[0007] The present invention has been made in view of the above circumstances, and aims to provide an electronic performance device which can naturally avoid monotony in performance while reducing the amount of information in the waveform data to be stored and the editing time by generating output waveform data by applying additional elements regardless of striking strength. [Means for solving the problem]

[0008] The invention of claim 1 is an electronic musical instrument comprising: a storage means for storing in advance waveform data for each striking strength obtained when striking a natural musical instrument; a striking section that can be struck during a performance; a detection means for detecting a strike on the striking section during a performance and for transmitting a detection signal relating to at least the striking strength of the strike; and an output means for outputting waveform data corresponding to the striking strength of the detection signal from among the waveform data stored in the storage means, on condition that the detection signal has been received from the detection means. The storage means stores basic waveform data corresponding to the striking strength of the natural musical instrument, and additional elements that are generated based on waveform data extracted from the same natural musical instrument separately from the basic waveform data, are applicable to a plurality of striking strengths, and are obtained by extracting elements of variation inherent in humans or natural musical instruments, and the output means outputs the waveform data stored in the storage means. basic The present invention is characterized in that it is possible to output output waveform data generated by adding the additional element to waveform data.

[0010] Claim 2 The invention described is characterized in that, in the electronic playing device described in claim 1, the storage means stores a plurality of the additional elements that are different from each other, and adds the different additional elements to a plurality of striking intensities, respectively. [Effects of the Invention]

[0011] According to the present invention, the storage means stores additional elements extracted from the elements of variation inherent in humans or natural musical instruments, and the output means is capable of outputting output waveform data generated by adding the additional elements to the waveform data stored in the storage means.Therefore, by generating output waveform data by applying the additional elements regardless of the striking strength, it is possible to reduce the amount of information in the waveform data to be stored and the editing time, while also naturally avoiding monotony in the performance.

[0013] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The electronic playing device of this embodiment is capable of electronically generating percussion sounds and outputting them during performance. As shown in Figure 1, it is configured with memory means 1 that pre-stores waveform data for each percussion intensity obtained when the instrument is struck, a percussion part R that can be struck during performance, detection means 2 that can detect strikes on the percussion part R during performance and is capable of transmitting a detection signal related to at least the percussion intensity of the strike, and output means 3 that, upon receiving a detection signal from the detection means 2, is capable of outputting waveform data from the waveform data stored in memory means 1 that corresponds to the percussion intensity of the detection signal.

[0014] As shown in Figure 6, the electronic playing device of this embodiment consists of an electronic drum R1, an electronic cymbal R2, etc., and can be played by a player striking, for example, the striking surface R1a of the electronic drum R1 (see Figures 7 to 12) or the striking surface R2a of the electronic cymbal R2 (see Figures 17 to 24) (the striking surfaces R1a and R2a correspond to the striking section R of the present invention) with a stick or the like.

[0015] The applicable electronic performance device may be a percussion instrument such as an electronic drum R1 or an electronic cymbal R2, or may be another electronic performance device that generates damped sounds, such as a keyboard instrument such as an electronic piano, or a string instrument such as an electronic guitar. For example, when the electronic performance device is applied to a keyboard instrument, the striking strength refers to the strength of a keystroke, and when the electronic performance device is applied to a string instrument, the striking strength refers to the strength of a string striking or plucking.

[0016] The storage means 1 is made up of a storage medium such as a memory that stores in advance waveform data for each striking strength obtained when striking a specific instrument corresponding to the electronic performance device (for example, a natural instrument known as an acoustic instrument, the sound of which is to be reproduced), and is capable of storing basic waveform data (A to H) obtained for each striking strength, as shown in Fig. 2. Such basic waveform data (A to H) consists of data representing sound waves that are generated by striking and attenuate over time, as shown in Figs. 13 and 25 (graphs in which the horizontal axis represents time and the vertical axis represents volume).

[0017] The detection means 2 is composed of a vibration sensor or the like attached to the striking portion R of the electronic musical instrument. For example, as shown in FIGS. 10 and 11, it may be vibration sensors (R1b, R1c) (head sensor and rim sensor) or vibration sensor R1d (side rim sensor) attached to the electronic drum R1, or as shown in FIGS. 20 to 24, it may be vibration sensors R2b, R2c, and R2d (vibration sensor, cup sensor, and edge sensor) attached to the electronic cymbal R2. When the detection means 2 detects a strike during performance, it is capable of transmitting a detection signal related to at least the strength of the strike to the output means 3. Note that the symbol t in FIGS. 10 and 11 denotes a cushion tape that elastically holds the vibration sensors (R1b, R1c).

[0018] The output means 3 is electrically connected to the storage means 1 and the detection means 2, and is capable of outputting waveform data (output waveform data) corresponding to the striking strength of the detection signal from the waveform data stored in the storage means 1 as a striking sound via a speaker or the like, on the condition that the output means 3 receives a detection signal from the detection means 2. In other words, when the striking part R is struck during performance, the output means 3 is capable of reproducing the sound of the instrument that has been recorded (sampled) and stored in advance, according to the striking strength.

[0019] A specific configuration of the electronic performance device will be described below. As shown in Figures 7 to 12, the electronic drum R1 is composed of a mesh-like striking surface R1a made of PET, nylon, or the like, a cylindrical shell 6 made of a resin such as ABS or nylon, lugs 10 made of a resin such as ABS or nylon or aluminum or zinc die-cast, side rims 5 made of a resin such as ABS or nylon, a hoop 8 made of steel or die-cast, a steel plate 12, and striking sensors (R1b, R1c).

[0020] Additionally, a hoop rubber 4 made of an elastic material such as EPDM rubber is fixed to the hoop 8. The shell 6 has a plurality of lugs 10 formed along the circumferential direction, and the striking surface R1a including the hoop rubber 4 and hoop 8 is fixed by tension bolts 7 attached to the lugs 10. As shown in Figures 11 and 12, the attachment portion of the lug 10 in the shell 6 according to this embodiment has an outwardly bent portion 6a and an inwardly bent portion 6b formed therein, ensuring rigidity.

[0021] 9 to 12, multiple sensor arrangement sections s are formed inside the shell 6, protruding from the periphery toward the center in a rotationally symmetrical manner about the central axis of the shell 6, and a plate 12 is disposed on each of the sensor arrangement sections s. A head sensor cushion 9 is attached to a specific plate 12. As shown in FIGS. 11 and 12, the head sensor cushion 9 is fixed onto the plate 12 with its tip abutting against the striking surface R1a. An impact sensor R1b, which constitutes a head sensor capable of detecting an impact on the striking surface R1a, is attached between the head sensor cushion 9 and the plate 12, and an impact sensor R1c, which constitutes a rim sensor capable of detecting an impact on the hoop rubber 4, is attached below the plate 12.

[0022] With this configuration, the head sensor cushion 9 and impact sensors (R1b, R1c) can be attached at any position inside the shell 6 (any position on the plate 12), allowing the number and placement of sensors to be flexibly changed to suit the model. Furthermore, an output jack J1 (see Figures 9 to 12) is attached at a specific position on the sensor placement section s in a manner that allows its position to be interchangeable with that of the plate 12, allowing the detection signal of the impact sensor R1b to be output from the output jack J1. The circuit board of the output jack J1 also serves as a cover that hides the internal wiring.

[0023] 11, the side rim 5 is attached to a predetermined position on the shell 6 and has a side rim rubber 5a that can be struck by the player, as well as an impact sensor R1d that constitutes a side rim sensor that can detect strikes on the side rim 5, and an output jack J2 (side rim output jack) that outputs the detection value detected by the impact sensor R1d. The side rim 5 in this embodiment is attached to the outer circumferential surface of the shell 6 via a rubber bushing 11, which ensures that the detection of strikes by the impact sensor R1d (side rim sensor) can be reliably separated from the detection of strikes by the impact sensors (R1b, R1c) (head sensor and rim sensor).

[0024] As shown in Figures 17 to 24, the electronic cymbal R2 is composed of a surface 13 (silicon rubber or the like) that forms the striking surface R2a, a frame 14 (resin such as ABS or nylon), and a cover 15 (EPDM rubber or the like). The surface 13 is made up of a portion that can be struck by a player with a stick or the like, and as shown in Figure 17, is composed of a cup portion R2aa, a bow portion R2ab, and an edge portion R2ac.

[0025] The center of the surface 13 is connected to the frame 14 via a rubber bushing 16, and impacts on the cup portion R2aa, bow portion R2ab, and edge portion R2ac are detected by impact sensors R2b, R2c, and R2d, and the detection signals can be output from an output jack J3. Note that the impact sensor R2b is a vibration sensor, and the impact sensors (R2c, R2d) (edge ​​sensor and cup sensor) are each made up of a seat switch sensor.

[0026] 24, the electronic cymbal R2 according to this embodiment has a curvature r2 of the peripheral portion of the frame 14 (near the portion where the impact sensor R2c is located) that is set to be larger than the curvature r1 of the inner peripheral portion of the frame 14 (the portion corresponding to the bow portion R2ab). As a result, even if the performer strikes the edge portion R2ac from an angle close to the horizontal, the angle at which the impact sensor R2c is located relative to the horizontal can be increased while maintaining a cymbal-like cross-sectional shape without excessively increasing the curvature r1, thereby ensuring reliable detection of impacts by the impact sensor R2c.

[0027] 21 and 24, the frame 14 according to this embodiment has hook-shaped locking portions 14a formed at the attachment locations of the cover 15. The cover 15 is attached to the frame 14 by fitting protrusions 15a (see FIGS. 22 and 24) formed on the cover 15 into the locking portions 14a. This makes it possible to avoid damage to screws and the like due to impacts, compared to fixing the cover 15 to the frame 14 with screws or the like.

[0028] As shown in Fig. 2, the storage means 1 according to this embodiment stores basic waveform data (A-H) corresponding to the striking strength of the musical instrument, and additional elements that are generated based on waveform data extracted separately from the basic waveform data (A-H) from the same musical instrument and that are applicable to a variety of striking strengths (in this embodiment, all striking strengths ranging from soft to hard strikes). The additional elements according to this embodiment are generated based on differential data that extracts the difference between two waveform data obtained with similar striking strengths. This extracts elements of the variability inherent in humans and natural musical instruments, and consists of differential waveform data such as the waveform data (α1) shown in Fig. 15 and the waveform data (α2) shown in Fig. 27.

[0029] Specifically, in the case of a striking strength similar to that of basic waveform data E, for example, the differential data according to this embodiment is obtained by acquiring two waveform data different from basic waveform data E (two waveform data obtained by striking the same instrument with a striking strength similar to that of basic waveform data E) and then calculating the difference between the values ​​of these two waveform data at the same time. An additional element is then obtained by multiplying this differential data by a predetermined coefficient, and this additional element is added (added or subtracted) to the basic waveform data to obtain output waveform data.

[0030] The predetermined coefficient can be a predetermined value or a value that changes appropriately during performance (for example, a value corresponding to a random number generated over time). The predetermined coefficient can also be set to 1, in which case the additional element is equal to the differential data, and output waveform data can be obtained by adding (adding or subtracting) the differential data to the basic waveform data.

[0031] For example, by striking an acoustic drum corresponding to electronic drum R1 with a predetermined striking strength and recording it, basic waveform data h1 can be obtained as shown in Figures 13 and 14, and differential data α1 can be calculated based on a striking strength similar to that of the electronic drum R1, as shown in Figure 15. Then, an additional element is calculated by multiplying the differential data α1 by a predetermined coefficient, and the additional element is added to the basic waveform data h1, thereby obtaining output waveform data h2 that is similar to the basic waveform data h1, as shown in Figure 16.

[0032] Furthermore, by striking an acoustic cymbal (natural musical instrument) corresponding to electronic cymbal R2 with a predetermined striking strength and recording it, basic waveform data h3 can be obtained as shown in Figures 25 and 26, and differential data α2, as shown in Figure 27, is calculated based on a striking strength similar to that of the cymbal. An additional element is then obtained by multiplying the differential data α2 by a predetermined coefficient, and this additional element is added to the basic waveform data h3, thereby obtaining output waveform data h4 that approximates the basic waveform data h3, as shown in Figure 28.

[0033] Therefore, when the striking surface (R1a, R2a) serving as the striking section of the present invention is struck, the output means 3 can output output waveform data obtained by adding additional elements to basic waveform data (A to H) according to the striking intensity.Therefore, for example, when the same striking surface is struck repeatedly in small increments during a roll performance, output waveform data that are similar to each other but are not identical will be output, including the variations inherent in humans and natural musical instruments, thereby preventing the same waveform data from being simply output repeatedly.

[0034] Furthermore, the storage means 1 according to this embodiment can generate output waveform data by arbitrarily changing the timing at which additional elements are added to basic waveform data at a given striking strength (by shifting the time at which the additional elements are added or subtracted). It is also possible to apply envelope processing that increases or decreases the volume, or to perform filter processing that adds additional elements only to a specified range of notes. Since envelope processing and filter processing are not performed on the basic waveform data, deterioration in the texture of the musical tone can be minimized. This allows various similar output waveform data to be generated while maintaining the texture, enabling a wide variety of output sounds.

[0035] Furthermore, the output means 3 according to this embodiment can output multiple pieces of output waveform data generated by adding additional elements randomly or in a preset manner. That is, multiple pieces of output waveform data can be generated with the same level of impact strength but with different additional elements added, and can be output randomly or in a preset manner according to the generated random numbers, etc.

[0036] Next, the control content of the electronic performance device according to this embodiment will be described with reference to the flowchart of FIG. First, when a strike on the striking section R is detected by the detection means 2 (S1), it is determined whether or not the strike is valid (S2), and if it is determined to be a valid strike, the strike strength is calculated (S3). Next, it is determined whether or not difference data (additional element) is to be added (S4), and if it is determined that difference data is to be added, it is determined whether or not filtering is required (S5). In this case, it is not limited to filtering, and it may also be determined whether or not other processing, such as envelope processing, is to be performed.

[0037] Thereafter, it is determined whether or not filtering should be performed (S6), and if it is determined that filtering should be performed, filtering is performed (S7) and differential data (additional elements) are added (S8), and if it is determined that filtering should not be performed, filtering is not performed and differential data (additional elements) are added (S8), thereby generating output waveform data (S9). The output waveform data thus obtained is output by the output means 3.

[0038] Next, an electronic performance device according to another embodiment of the present invention will be described. 1, the electronic musical instrument according to this embodiment is capable of electronically generating percussion sounds and outputting them during performance, and is configured to include storage means 1 that stores in advance waveform data for each percussion intensity obtained when a musical instrument (for example, an acoustic musical instrument corresponding to the electronic musical instrument) is struck, detection means 2 that can detect strikes on the striking section R during performance and transmit a detection signal related to at least the percussion intensity of the strike, and output means 3 that can output waveform data corresponding to the percussion intensity of the detection signal from the waveform data stored in storage means 1, on the condition that a detection signal is received from detection means 2. Note that detailed description of the same components as those in the previous embodiment will be omitted.

[0039] Here, the storage means 1 according to this embodiment is configured to store a plurality of additional elements (two pieces of difference data α and β in this embodiment) and to select the additional element to be applied according to the striking strength, as shown in Fig. 4. That is, the storage means 1 stores basic waveform data (A to H) according to the striking strength of the musical instrument, and additional elements (difference data α and β) generated based on waveform data extracted separately from the basic waveform data (A to H), and to select the additional element to be added according to the striking strength, as shown in Fig. 4.

[0040] Specifically, in the region of relatively weak impact intensity (region of basic waveform data A and B), an additional element obtained by multiplying the difference data α by a predetermined coefficient is added to the basic waveform data A or B to generate output waveform data. In the region of relatively strong impact intensity (region of basic waveform data E to H), an additional element obtained by multiplying the difference data β by a predetermined coefficient is added to the basic waveform data (E to H) to generate output waveform data. In the region of intermediate impact intensity (region of basic waveform data C and D), an additional element obtained by multiplying the difference data α by a predetermined coefficient is added to the basic waveform data C or D, and then an additional element obtained by multiplying the difference data β by a predetermined coefficient is added to generate output waveform data. In this way, as in the previous embodiment, the additional element according to this embodiment can be applied to a plurality of impact intensities (in this embodiment, the region of strong impact intensity, the region of weak impact intensity, and the region between them).

[0041] Next, the control content of the electronic performance device according to this embodiment will be described with reference to the flowchart of FIG. First, when a strike on the striking section R is detected by the detection means 2 (S1), it is determined whether or not the strike is valid (S2), and if it is determined to be a valid strike, the strike strength is calculated (S3). Next, it is determined whether or not differential data (additional element) is to be added (S4), and if it is determined that differential data is to be added, it is determined whether or not filtering is required (S5). In this case, as in the previous embodiment, it is not limited to filtering, and it may also be determined whether or not other processing, such as envelope processing, is to be performed.

[0042] Thereafter, the processes of S6 to S9 (processing related to the differential data α) and S11 to S14 (processing related to the differential data β) are performed in parallel. In the process related to the differential data α, it is determined whether or not to add the differential data α (S6). If it is determined that the differential data α should be added, it is determined whether or not to perform filtering (S7). If it is determined that filtering should be performed, filtering is performed (S8) and the differential data α (additional element) is added (S9). If it is determined that the filtering should not be performed, the differential data α (additional element) is added without filtering (S9), thereby generating output waveform data (S10). The output waveform data obtained in this manner is output by the output means 3.

[0043] On the other hand, in the process related to the differential data β, it is determined whether or not to add the differential data β (S11). If it is determined that the differential data β should be added, it is determined whether or not to perform filtering (S12). If it is determined that filtering should be performed, the filtering is performed (S13) and the differential data β (additional element) is added (S14). If it is determined that the filtering should not be performed, the differential data β (additional element) is added without performing filtering (S14), thereby generating output waveform data (S10). The output waveform data thus obtained is output by the output means 3. Note that if it is not determined in S6 that the differential data α should be added, or if it is not determined in S11 that the differential data β should be added, the process skips S7 to S9 and S12 to S14 and proceeds to S10.

[0044] According to the above embodiment, the storage means 1 stores basic waveform data corresponding to the striking intensity and additional elements that are generated based on waveform data extracted separately from the basic waveform data (A to H) and that can be applied to a plurality of striking intensities, and the output means 3 is capable of outputting output waveform data generated by adding additional elements to the basic waveform data.Therefore, by generating output waveform data by applying additional elements regardless of the striking intensity, it is possible to reduce the amount of information in the waveform data to be stored and the editing work time, while naturally avoiding monotony in the performance.

[0045] Furthermore, the additional elements according to this embodiment are generated based on differential data, which extracts the difference between two waveform data sets acquired with similar striking strengths. This facilitates the generation of output waveform data that closely resembles the fundamental waveform data. In particular, this embodiment extracts the inherent variability of human and acoustic instruments as the difference between the two waveform data sets acquired with similar striking strengths. By adding this difference to the fundamental waveform data to generate output waveform data, the musical tone can be naturally transformed. Furthermore, the additional elements according to this embodiment are obtained by multiplying the differential data by a predetermined coefficient, which increases the variation in the generated output waveform data and allows for more natural performances. Furthermore, because only the differential data, which extracts the inherent variability of human and acoustic instruments, is multiplied by the coefficient, the texture of the fundamental waveform data is maintained, minimizing degradation of the texture of the output waveform data.

[0046] In addition, various output waveform data that approximate the basic waveform data at a predetermined striking strength can be generated by arbitrarily changing the timing at which additional elements are added, or by performing envelope processing that increases or decreases the volume, or by performing filter processing that adds additional elements only to a predetermined range, thereby further improving the variety of the generated output waveform data and significantly reducing deterioration in the texture of the musical tone compared to a method that applies filter processing to the basic waveform data itself to add changes.Furthermore, if the output means 3 of the present invention can be configured to output multiple output waveform data generated by adding additional elements randomly or in a predetermined manner, appropriate output waveform data can be smoothly output during performance.

[0047] Furthermore, according to another embodiment of the present invention, a plurality of additional elements are stored and the additional element to be applied is selected according to the impact strength, so that appropriate output waveform data can be output according to the impact strength. Any of the plurality of additional elements may be applied to the impact strength, and for example, different additional elements may be added to each of the impact strengths (A to H).

[0048] While the present embodiment has been described above, the present invention is not limited to this. For example, the additional elements are not limited to those generated based solely on differential data, but may be generated using performance-related parameters other than basic waveform data. Specifically, the detection means 2 detects the strength of the strike on the striking unit R during performance, as well as the part of the striking unit R struck, the time interval between strikes (the time elapsed since the previous strike), and the pressure applied to the striking unit R, and can use these detected values ​​as parameters to construct additional elements and generate and output output waveform data. Furthermore, if an electronic hi-hat with a top cymbal and a bottom cymbal facing each other and capable of coming into or separating from each other is used as the striking unit R, the additional elements may be varied depending on the distance between the top cymbal and the bottom cymbal.

[0049] Furthermore, the additional elements of the present invention are not limited to being generated only from recorded waveform data of the same instrument, and sufficient effects can be obtained even if the additional elements are generated from recorded waveform data of other closely similar instruments. Alternatively, the additional elements may be generated based on waveform data recorded by changing the type and tension of the striking surface of the instrument, the type and tension of the resonating wires and strings, the plectrum, hammer, microphone, and other recording equipment used in the performance, or waveform data recorded of a similar instrument. [Industrial Applicability]

[0050] The storage means stores additional elements that are generated based on basic waveform data corresponding to the striking strength of the natural musical instrument and waveform data extracted separately from the basic waveform data from the same natural musical instrument, are applicable to a plurality of striking strengths, and are extracted to account for the elements of variation inherent in humans or natural musical instruments. The output means outputs the additional elements stored in the storage means. basic As long as the electronic performance device is capable of outputting output waveform data generated by adding additional elements to waveform data, it can also be applied to devices with different external shapes or devices with added functions.
