Each electronic pad is a device that simulates each percussion instrument (snare drum, kick drum, tom, hi-hat, cymbal, etc.) constituting an acoustic drum set. Each electronic pad includes a hitting surface portion to be hit with a drum stick, a brush, and the like, and a sensor portion for detecting a vibration mode (vibration waveform) of the hitting surface portion and outputting a hitting signal representing the detected vibration mode. Have. Note that an apparatus in which a percussion instrument constituting an acoustic drum set is attached with a pickup device that detects a vibration of the percussion surface of the percussion instrument and outputs a percussion signal representing the vibration mode is also regarded as an electronic pad. The control device C includes a musical sound generating device 20 that generates a striking sound corresponding to the signal acquired from each electronic pad, and a setting device that is used when creating or editing setting information SI that defines the operation of the musical sound generating device 20. 30.

  Next, the configuration of the tone generation device 20 will be described. As shown in FIG. 2, the tone generator 20 includes a setting operator 21, an operator interface circuit 22, a display 23, a display control circuit 24, a sound source circuit 25, a sound system 26, a computer unit 27, a storage device 28, and an external device. An interface circuit 29 is provided.

  The setting operator 21 is provided on the operation panel of the tone generation device 20. The user mainly creates or edits the setting information SI of the musical sound generation device 20 using the setting device 30 described later. However, the user can also create or edit the setting information SI using the setting operator 21. The setting operator 21 is connected to the operator interface circuit 22. Each electronic pad as a performance operator of the present invention is also connected to the operator interface circuit 22.

The operator interface circuit 22 has a plurality of connection terminals IN ₁ , IN ₂ ,... For connecting the plurality of electronic pads PD ₁ , PD ₂ ,. In the following description, an electronic pad connected to the connection terminal IN _{n (= 1, 2,..., 12)} is referred to as an electronic pad PD _{n (= 1, 2,..., 12)} . In the present embodiment, twelve connection terminals are provided, but the number of connection terminals is not limited to twelve. Moreover, the user does not necessarily need to connect an electronic pad to all the connection terminals. For example, a simple electronic drum set may be configured by connecting 6 to 7 electronic pads, or a complex electronic drum set may be configured by connecting electronic pads one by one to all connection terminals. Also good. The operator interface circuit 22 supplies operation information (that is, a batting signal) indicating the operation contents of each electronic pad to the computer unit 27 via the bus 2a.

  The display 23 is composed of a liquid crystal display (LCD), a 7-segment LED, and the like, and displays characters, figures, and the like. The display 23 is controlled by a display control circuit 24. The display control circuit 24 acquires image data representing an image to be displayed on the display 23 from the computer unit 27 described later via the bus 2a, and controls the display 23 based on the acquired image data.

  The tone generator circuit 25 includes a waveform memory that stores waveform data representing a plurality of musical tone waveforms. The waveform data specified by the computer unit 27 (to be described later) is read from the waveform memory to generate a digital musical tone signal. 26. That is, the tone generator circuit 25 generates a digital musical tone signal representing a percussion sound corresponding to the hit electronic pad and supplies it to the sound system 26. The sound system 26 is a D / A converter that D / A converts the digital musical tone signal supplied from the sound source circuit 25 into an analog musical tone signal, an amplifier that amplifies the converted analog musical tone signal, and the amplified analog musical tone signal. A speaker that converts the signal into an output is provided.

  The computer unit 27 includes a CPU 27a, a timer 27b, a ROM 27c, and a RAM 27d connected to the bus 2a. The CPU 27a supplies musical tone information (information specifying waveform data, information indicating sound intensity, etc.) necessary for sound generation to the tone generator circuit 25 in accordance with the batting signal acquired from each electronic pad. The timer 27b outputs an interrupt signal to the CPU 27a at a cycle preset by the CPU 27a. The ROM 27c is a semiconductor memory (for example, a rewritable flash memory) incorporated in advance in the musical sound generation device 20, and stores various programs and various data. These various programs and various data may be recorded in advance in each recording medium, or may be taken in from the outside via an external interface circuit 29 described later. The RAM 27d is a semiconductor memory that temporarily stores data necessary for executing various programs.

For example, the current setting information SI is stored in the RAM 27d. As shown in FIG. 3, the setting information SI is composed of a plurality of parameters. Specifically, the setting information SI includes trigger setting information TI and tone color setting information VI. Trigger setting information TI includes pad-type PT _n for specifying the model of the electronic pad PD _n. Pad type PT _n represents the model name of the model name or pick-up device of the pad.

The trigger setting information TI includes a threshold level TH _n , a wait time WT _n , and a reject time RT _n that are used when determining whether or not crosstalk has occurred. As shown in FIG. 4, CPU 27a is sequentially sampled striking signals output from the electronic pad PD _n, to calculate the envelope value EV _n representing the envelope of the striking signal (change in amplitude). State of the electronic pad PD _n is divided into three states (wait state, reject state and an idle state). A period from timing t1 when the calculated envelope value EV _n exceeds the threshold level TH _n to timing t2 when the wait time WT _n has elapsed is referred to as a wait state. Note that the wait time WT _n is slightly shorter than the time taken from the timing t1 until the envelope value reaches the maximum. In other words, at the time when the wait time WT _n has elapsed from the timing t1, the envelope value is large enough to be adopted as an index of the strength of the hit. The period until the timing t3 the expiration of rejected time RT _n from the timing t2 is called a reject state. From the timing t3, below the threshold level TH _n by the envelope value EV _n is gradually decreased, it increased again envelope value EV _n, referred to as the period from the timing t1 exceeding the threshold level TH _n idle. Further, as will be described in detail later, the envelope value EV _n is sequentially updated, but the envelope value EV _{n at the} timing t2 is a time sufficiently longer than the predetermined time td (the wait time WT _n (for example, the wait time WT _n is more than 30 times))). That is, as indicated by the broken line in the figure, the envelope value actually changes after the timing t2, but as indicated by the thick solid line in the figure, until the predetermined time td elapses from the timing t2. The envelope value EV _n is not updated. In the wait state, the peak value of the envelope value is latched.

Furthermore, the trigger setting information TI includes crosstalk coefficients C _{n, m} for calculating the strength of cross-talk which may occur in the electronic pad PD _n connected to the connection terminal IN _n. Crosstalk coefficients C _{n, m} is in the case of the electronic pad PD _m is hit in a state where the electronic pad PD _n are not hit, output from the intensity and the electronic pad PD _m of the striking signals output from the electronic pad PD _n It corresponds to the ratio with the strength of the hit signal. The parameter value that has not been set is “N / A”.

The tone color setting information VI includes information for specifying a tone color assigned to the electronic pad PD _n . For example, tone color setting information VI includes timbre name VN _n is the name of the tone color to be assigned to the electronic pad PD _n.

  The user can assign names to the trigger setting information TI and the timbre setting information VI, and the trigger setting information TI and the timbre setting information VI can be stored as separate information in the ROM 27c or the storage device 28 described later. The trigger setting information TI and the timbre setting information VI stored in the ROM 27c or the storage device 28 are read out according to an instruction from the user and used as the current setting information SI. However, the trigger setting information TI and the tone color setting information VI constituting the current setting information SI may be associated with each other and stored in the ROM 27c or the storage device 28. In this case, if one of the trigger setting information TI and the tone color setting information VI is selected, the other information associated with the specified information may be automatically selected.

  The storage device 28 includes a large-capacity nonvolatile recording medium such as HDD, FDD, CD-ROM, MO, DVD, and a drive unit corresponding to each recording medium, and can store and read various data and programs. I have to. These data and programs may be stored in the storage device 28 in advance, or may be taken in from the outside via the external interface circuit 29.

  The external interface circuit 29 enables the musical sound generation device 20 to be connected to a setting device 30, an external device compatible with MIDI, or the like wirelessly or by wire, and can be connected to a communication network such as the Internet. Only one external device may be connected to the musical sound generating device 20, or a plurality of external devices may be simultaneously connected to form a network by the musical sound generating device 20 and the plurality of external devices. Also good.

  Next, the configuration of the setting device 30 will be described. The setting device 30 is composed of a portable information terminal such as a tablet computer or a mobile phone, and is a device (user) for inputting various parameters constituting the setting information SI of the musical sound generating device 20 by executing a predetermined parameter setting program.

The setting operator 31 includes a power switch for turning the setting device 30 on and off, a home button for displaying a selection screen for selecting other software during execution of the software, and the like. The setting operator 31 is connected to an operator interface circuit 35 described later.

  The display 32 is configured by a liquid crystal display (LCD), and displays characters, figures, and the like on a display screen. The display 32 is controlled by a display control circuit 33. The display control circuit 33 acquires image data representing an image to be displayed on the display device 32 from a computer unit 37 (described later) via the bus 3a, and controls the display device 32 based on the acquired image data.

  The touch panel 34 is disposed so as to overlap the display screen of the display device 32. The touch panel 34 is also connected to the operator interface circuit 35 and is controlled by the operator interface circuit 35 to output coordinate data representing the coordinates of the position touched by the user to the operator interface circuit 35. In the following description, an icon displayed on the display 32 and which can be turned on / off is simply referred to as a button. Further, touching the operation area of the touch panel 34 corresponding to the button-type icon display area with a finger, a pen, or the like is simply referred to as “button pressing”. Also, releasing a finger, pen, or the like that pressed the button from the touch panel 34 is simply referred to as “release the button”.

  The operator interface circuit 35 supplies various data relating to the operation of the setting operator 31 and the operation of the touch panel 34 to the computer unit 37 via the bus 3a.

  The sound system 36 includes a D / A converter that D / A converts a digital musical tone signal (for example, a warning tone) supplied from the computer unit 37 into an analog musical tone signal, an amplifier that amplifies the converted analog musical tone signal, and an amplified signal. There is also provided a speaker for converting an analog musical sound signal into an acoustic signal and outputting it.

  The computer unit 37 includes a CPU 37a, a timer 37b, a ROM 37c, and a RAM 37d. The CPU 37a executes a parameter setting guide program, which will be described later, to cause the user to perform operations for setting various parameters, and causes the CPU 27a of the tone generation device 20 to set various parameters according to the operations. The timer 37b outputs an interrupt signal to the CPU 37a at a cycle preset by the CPU 37a. The ROM 37c is a semiconductor memory (for example, a rewritable flash memory) built in the setting device 30 in advance, and stores various programs and various data. These various programs and various data may be recorded in the ROM 37c in advance, or may be taken in from the outside via the external interface circuit 39 described later. The RAM 37d is a semiconductor memory that temporarily stores data necessary for executing various programs.

  The storage device 38 is a large-capacity nonvolatile recording medium such as a flash ROM or a hard disk, and can store and read various data and programs. These data and programs may be stored in advance in the storage device 38 or may be taken in from the outside via the external interface circuit 39.

  The external interface circuit 39 makes it possible to connect the setting device 30 to the musical sound generating device 20, an external device compatible with MIDI, or the like wirelessly or by wire, and also connectable to a communication network such as the Internet. Only one external device may be connected to the setting device 30, or a plurality of external devices may be simultaneously connected to form a network by the setting device 30 and the plurality of external devices. .

  Next, the operation of the control device C will be described. When the musical sound generating device 20 is turned on, the CPU 27a reads predetermined trigger setting information TI and timbre setting information VI from the storage device 28 and sets them in a usable state as the current setting information SI. For example, the CPU 27a reads the latest trigger setting information TI and tone color setting information VI. As a result, the electronic percussion instrument 10 is ready to be played. In this state, the musical sound generation device 20 can communicate with the setting device 30. Since the operation of the control device C when playing the electronic percussion instrument 10 is the same as the conventional one, its description is omitted.

  Next, the operation of the control device C when creating or editing the setting information SI of the tone generation device 20 will be described. First, the operation of the setting device 30 will be described, and then the operation of the musical tone generation device 20 will be described.

  When the setting device 30 is turned on, the CPU 37a activates the operating system and displays a program selection screen on the display 32. Various program icons stored in the ROM 37c and the storage device 38 are displayed on the program selection screen. When the user touches the icon of the parameter setting guide program that sequentially displays the operation contents for setting various parameters, the CPU 37a starts the parameter setting guide process in step S10 as shown in FIG. .

  Next, the CPU 37a executes an initialization process in step S11. In this initialization process, as shown in FIG. 7, an image is displayed that allows the user to select either new setting information SI or editing the current setting information SI. Specifically, a new creation button CN and an edit start button EC are displayed. The new creation button CN displays “Create New Setting”. The edit start button EC displays “Edit Current Setting”. When the user selects to newly create the setting information SI (when the new creation button CN is touched), the CPU 37a is information indicating that each parameter constituting the current setting information SI is initialized. Is transmitted to the musical sound generating device 20. Thereby, all the parameters constituting the current setting information SI are set to “N / A”. Then, the CPU 37a receives the current setting information from the tone generation device 20. On the other hand, when the user selects to edit the current setting information SI (when the edit start button EC is touched), the CPU 37a indicates that each parameter constituting the current setting information SI is initialized. The current setting information SI is received from the tone generation device 20 without transmitting information to the tone generation device 20.

Then, CPU 37a, at step S12, a tone assigned to the pad type and electronic pads PD _n of the electronic pad PD _n, is selected by the user. In step S12, as shown in FIG. 8, the image is displayed for selecting a tone color to be assigned to the image and the electronic pad PD _n to select the pad type of electronic pads PD _n. That is, twelve buttons PS ₁ to PS ₁₂ corresponding to the connection terminals IN ₁ to IN ₁₂ are displayed on the upper part of the display screen of the display 32. The buttons PS ₁ to PS ₁₂ have a rectangular frame. Image corresponding to the pad-type PT _n configuration information SI said received is displayed in a frame of the button PS _n. However, if the pad-type PT _n is not set, it is displayed as "N / A" in the frame of the button PS _n. In addition, a button NX that is pressed when proceeding to the next setting is displayed on the upper end portion of the display screen of the display 32.

The user presses _one of the buttons PS ₁ to PS ₁₂ to select a setting target electronic pad. When the user strikes the electronic pad, the musical sound generating device 20 may be configured to supply the setting device 30 with information specifying the hit electronic pad. Thereby, the configuration may be such that an electronic pad to be set is selected. The color of the button corresponding to the selected electronic pad is inverted. Thereby, the user can recognize which electronic pad is selected as the current setting target.

Below the buttons PS ₁ ~ button _{PS 12,} button TY for setting the pad type PT _n of the selected electronic pad PD _n are displayed. The button TY, based on the setting information SI to the received, pad type PT _n electronic pad PD _n of the selected is displayed. However, if the pad-type PT _n is not set, it is displayed as "N / A" on the button TY. When the user touches the button TY, a list of selectable pad types is displayed. This list is created for each category to which each pad type belongs (kick drums, snare drums, cymbals, toms, etc.). The list also includes model names of pickup devices that can be attached to the percussion instruments that make up the acoustic drum set. The user of the displayed list, select the pad type of electronic pads PD _n that said selected. Then, the image corresponding to the category in which the selected pad type belongs, is displayed in a frame of the button PS _n. For example, when the selected pad type belongs to the kick drums, an image representing the kick drum is displayed. For example, when the selected pad type is a pickup device, an image of the pickup device is displayed.

Below the buttons TY, buttons NM for allocating tones to the electronic pad PD _n that the selection is displayed. The button NM displays the timbre name VN _{n of the} selected electronic pad PD _n based on the received setting information SI. However, when the timbre name VN _n is not set, “N / A” is displayed on the button NM. When the user touches the button NM, a list of selectable timbres is displayed. The user of the displayed list, selects a tone color to be assigned to the electronic pad PD _n that said selected.

CPU37a transmits information n that identifies the electronic pad PD _n to be set, the pad type PT _n and tone name VN _n that the chosen tone generation apparatus 20. The musical sound generating device 20 updates the parameter related to the electronic pad PD _n corresponding to the transmitted information n in the current setting information SI. That is, the musical sound generating apparatus 20, on the basis of the transmitted pad-type PT _n and tone name VN _n, and updates the current configuration information SI. Note that the threshold level TH, the wait time WT, and the reject time RT are determined in advance for each pad type PT and stored in the ROM 27c. The CPU 27a updates the threshold level TH _n , wait time WT _n and reject time RT _n according to the selected pad type PT _n .

However, in the case of an electronic pad configured by attaching a pickup device to a percussion instrument constituting an acoustic drum set, it is necessary to consider not only the characteristics of the pickup device but also the characteristics of the percussion instrument. Therefore, in this case, the user, in step S12, using the setting device 30, as well as select the pad type PT _n, and inputs the threshold level TH _n, the wait time WT _n and reject time RT _n. Specifically, the selected pad-type PT _n is when a pick-up device, the threshold level TH _n, 3 two sliders respectively corresponding to the wait time WT _n and reject time RT _n is displayed on the display unit 32. The user slides the slider to input the threshold level TH _n , wait time WT _n and reject time RT _n .

Then, CPU 37a is information n that identifies the electronic pad PD _n to be set, the selected pad-type PT _n and tone name VN _n, and the threshold level TH _n, the wait time WT _n and reject time RT _n musical sound generating Transmit to device 20. The musical sound generating device 20 updates the parameter related to the electronic pad PD _n corresponding to the transmitted information n in the current setting information SI. That is, the musical sound generating apparatus 20, the transmitted pad-type PT _n and tone name VN _n, and on the basis of the threshold level TH _n, wait time WT _n and reject time RT _n, and updates the current configuration information SI.

  When the setting of the pad type and tone color of one electronic pad is completed, the user selects another pad and sets the pad type and tone color of the selected other electronic pad. In this way, the user repeats the same operation for each electronic pad that requires setting of the pad type and tone color. When the pad type and tone color settings are completed, the user presses the button NX. When the button NX is pressed, the CPU 37a advances the process to step S13.

Next, in step S13, the CPU 37a displays an operation procedure for setting a crosstalk coefficient on the display 32, reads out from the ROM 12c and executes a crosstalk coefficient setting guide program for guiding a user operation. As shown in FIG. 9, the CPU 37a starts a crosstalk coefficient setting guide process in step S130. Next, in step S131, the CPU 37a instructs the music sound generating device 20 to start a crosstalk coefficient setting process (FIGS. 11A and 11B) described later. Next, the CPU 37a causes the user to strike each electronic pad three times. Specifically, in step S132, the CPU 37a sets an index k for designating an electronic pad to be hit to “1”. Then, CPU 37a determines in step S133, whether the electronic pad to the connection terminal IN _k are connected. Specifically, it is determined whether or not the pad type PT _k is “N / A”. When the pad type PT _k has been set, it is determined that an electronic pad is connected to the connection terminal IN _k . On the other hand, when the pad type PT _k is not set, it is determined that the electronic pad is not connected to the connection terminal IN _k . Even if the electronic pad is connected to the connection terminal IN _k , if the pad type PT _k is not set (“N / A”), it is determined that the electronic pad is not connected to the connection terminal IN _k. The If the electronic pad to the connection terminal IN _k is determined not to be connected, CPU 37a advances the process to step S137 described later. On the other hand, if the electronic pad is determined to be connected to the connection terminal IN _k, at step S134, as shown in FIG. 10, strikes the electronic pad PD _k connected to the connection terminal IN _k An image instructing this is displayed. This image includes a number representing the remaining number of hits. Each time the electronic pad PD _k instructed to strike is hit, the remaining number of hits decreases. The user strikes the electronic pad PD _k three times according to the instruction. Then, the musical sound generation device 20 updates the crosstalk coefficient related to the electronic pad different from the hit electronic pad PD _k . The setting process of the crosstalk coefficient by the tone generator 20 will be described later. Then, CPU 37a, at step S135, the tone generation apparatus 20, receives the music information indicating that the electronic pad PD _k is hit (MIDI data). Then, CPU 37a determines in step S136, by using the music information thus received, whether hit number of the electronic pad PD _k which indicates that said striking reached 3 times. If number of hits electronic pad PD _k which indicates that said striking is less than 3 times, CPU 37a advances the process to step 134 determines "No". On the other hand, when the number of hits electronic pad PD _k which indicates that said striking reached 3 times, CPU 37a determines the result as "Yes", the process proceeds to step S137. Next, the CPU 37a increments the index k in step S137. In step S138, the CPU 37a determines whether or not all electronic pads have been hit. Specifically, the CPU 37a determines whether or not the index k exceeds “12”. If the index k exceeds “12”, it is determined that all the electronic pads have been hit. On the other hand, if the index k is “12” or less, it is determined that there is an electronic pad that has not been hit yet. If there is an electronic pad that has not been hit yet, the CPU 37a determines “No” and proceeds to step S133. On the other hand, if all the electronic pads have been hit, the CPU 37a determines “Yes” and instructs the music sound generation device 20 to end the crosstalk coefficient setting process in step S139. In step S13a, the CPU 37a ends the crosstalk coefficient setting guide program and returns to the parameter setting guide program. And CPU37a complete | finishes a parameter setting guide program in step S14.

Next, the operation of the tone generation device 20 will be described. In response to the instruction from the setting device 30, the CPU 27a reads the crosstalk coefficient setting program shown in FIGS. 11A and 11B from the ROM 27c and executes it. In step S20, the CPU 27a starts a crosstalk coefficient setting process. Next, CPU27a performs the initialization process in step S21. For example, the crosstalk coefficients C _{n = 1 to 12 and m = 1} to ₁₂ are set to “0”. Also, it sets the hold flag HF _i indicating whether or not in holding _the envelope value EV n _{= 1 to 12} of the striking signals for each electronic pad "not hold". Also, an index i for selecting a processing target pad, which will be described below, is set to “1”.

Next, in step S22, the CPU 27a determines whether or not a pad is connected to the connection terminal IN _i . Specifically, if the pad type PT _i is not set, the CPU 27a determines “No”, increments the index i in step S23, and advances the process to step S22. As a result of incrementing the index i, when the value exceeds the maximum value “12”, the value is set to “1”. On the other hand, if the pad type PT _i has been set, the process proceeds to step S24.

Next, in step S24, the CPU 27a refers to the holding flag HF _i and determines whether or not the envelope value EV _i is being held. If the hold flag HF _i is "in holding", CPU 27a determines the result as "Yes", the process proceeds to step S26. On the other hand, if the holding flag HF _i is “non-holding”, the CPU 27a determines “No”, acquires the hit signal of the electronic pad PD _i , and calculates the envelope value EV _i in step S25. . In the wait state, the CPU 27a calculates an envelope value based on the hit signal and latches the peak value. In other words, when the newly calculated envelope value is larger than the previously calculated envelope value, the newly calculated envelope value is stored.

Next, the CPU 27a executes Steps S26 to S28 to determine whether or not crosstalk has occurred in the electronic pad PD _i (hereinafter referred to as an electronic pad PD _i to be processed). The crosstalk coefficient setting process is executed at high speed. That is, in the setting device 30, when the electronic pad PD _k selected as striking target is once struck, the tone generation device 20, whether the crosstalk occurs determination is performed to each electron pad.

First, in step S26, the CPU 27a determines whether or not the electronic pad PD _{i to} be processed has transitioned from the wait state to the reject state (whether or not the wait time WT _i has elapsed since the transition to the wait state). To do. When the electronic pad PD _{i to} be processed remains in any of the wait state, reject state, and idle state, when transitioning from the idle state to the wait state, and when transitioning from the reject state to the idle state In any case, the CPU 27a advances the process to step S2f. On the other hand, when the electronic pad PD _{i to} be processed transitions from the wait state to the reject state (when the wait time WT _i has elapsed since the transition to the wait state), the CPU 27a sets the holding flag HF _i in step S27. Set to “holding” and start holding envelope value EV _i . When a predetermined time td has elapsed since the start of holding the envelope value EV _i , the holding flag HF _i is set to “not holding”.

Then, CPU 27a determines in step S28, whether the crosstalk occurs in the electronic pads PD _i to be processed. Specifically, the CPU 27a multiplies the envelope value EV _{j ≠ i} of electronic pads other than the processing target by the crosstalk coefficient C _{i, j} , respectively. The index j is an arbitrary number different from the index i among “1” to “12”. The multiplication result is compared with the envelope value EV _i of the electronic pad to be processed. When all the multiplication results are larger than the envelope value EV _i , the CPU 27a determines “Yes” and proceeds to step S2f. On the other hand, when at least one of the multiplication results is equal to or less than the envelope value EV _i , the CPU 27a determines “No”, and in step S29, based on the envelope value EV _i and the timbre name VN _i , the musical tone. Information is generated and supplied to the tone generator circuit 25, and a musical sound corresponding to the hit of the electronic pad to be processed is generated. Next, in step S2a, the CPU 27a supplies the musical tone information (or MIDI data corresponding to the musical tone information) to the setting device 30 (see step S135 in FIG. 9).

Then, CPU 27a, at step S2b, among envelope values _EV 1 _{~EV 12,} selects the maximum envelope value EV _p. Next, in step S2c, the CPU 27a determines whether or not the electronic pad PD _{i to} be processed has been truly hit. That is, the CPU 27a determines whether or not the value of the index p of the selected envelope value EV _p is the same as the value of the index i of the electronic pad to be processed. When the value of the index p is the same as the value of the index i, the CPU 27a determines “Yes” and advances the process to step S2f. On the other hand, when the value of the index p is different from the value of the index i, the CPU 27a determines “No”, and in step S2d, the envelope value EV _i of the electronic pad to be processed and the selected envelope value EV _p The ratio R (= EV _i / EV _p ) is calculated. Next, when the calculated ratio R is larger than the crosstalk coefficient C _{i, p} , the CPU 27a updates the crosstalk coefficient C _{i, p} to the calculated ratio R in step S2e. In step S2f, the CPU 27a determines whether or not the setting device 30 has instructed to end the crosstalk coefficient setting process. When it is not instructed by the setting device 30 to end the crosstalk coefficient setting process, the CPU 27a determines “No”, increments the index i of the electronic pad to be processed in step S2g, and performs step S22. Proceed with the process. However, as a result of incrementing the index i, when the value exceeds the maximum value “12”, the value is set to “1”. Thereafter, the CPU 27a repeatedly executes steps S22 to S2g. In step S2f, when instructed by the setting device 30 to end the crosstalk coefficient setting process, the CPU 27a determines “Yes” and ends the crosstalk coefficient setting process in step S2h.

Next, a specific example of the crosstalk coefficient setting process of the tone generation device 20 will be described. In this example, in order to simplify the explanation, it is assumed that _three electronic pads PD _{1 to} PD ₃ are connected to the connection terminals IN _{1 to} IN ₃ , respectively. Then, the setting device 30, the electronic pads _PD 1 -PD ₃ are sequentially selected as the strike target, the user strikes in order to electronic pad _PD 1 -PD ₃ three times, respectively. It is assumed that when any one electronic pad is hit, the other two electronic pads also vibrate. That is, when one electronic pad is hit, crosstalk occurs in another electronic pad.

First, the envelope value _EV 1 _{~EV 3,} and crosstalk coefficients _C 1, 3 _{-C 3,3,} holding flag _HF 1 _{~HF 3,} the index i is initialized (step S21).

When the electronic pad PD ₁ is hit, the electronic pad PD ₁ starts to vibrate first, and the electronic pad PD ₂ and the electronic pad PD ₃ begin to vibrate later than the electronic pad PD ₁ . Hereinafter, an example in which the electronic pad PD ₁ , the electronic pad PD ₂ , and the electronic pad PD ₃ start to vibrate in this order will be described. In this example, it is determined that each electronic pad has transitioned from the wait state to the reject state in the same order as the vibration start order. That is, the electronic pad is determined from the first wait state that the shift in the reject state, the electronic pad PD _1. Accordingly, as shown in FIG. 12A, in the previous state of the electronic pad PD ₁ transitions from the wait state to the reject state, the crosstalk coefficient is not updated (i = 1 to 3, Step S26: No). In the meantime, the envelope values EV _{1 to} EV ₃ are sequentially updated (i = 1 to 3, step S25).

When the electronic pads PD ₁ transitions from the wait state to the reject state (i = 1, step S26), as shown in FIG. 12B, the envelope value EV ₁ is started retained (step S27). That is, in the period until passage of a predetermined time td from the timing, the envelope value EV ₁ is not updated. In this example, the envelope value EV ₁ to be held is “100”. At this timing, the electronic pad PD ₂ and the electronic pad PD ₃ also start to vibrate and have already transitioned from the idle state to the wait state. The latest of the envelope values EV ₂ is "43". In addition, the latest of the envelope value EV ₃ is "30". However, the envelope value EV ₂ and envelope value EV ₃ is not yet started retained. In other words, the envelope value EV ₂ and the envelope value EV ₃ may be updated. Therefore, after this, when the envelope value EV ₂ is calculated (i = 2, step S25), and the envelope value EV ₂ is likely to increase slightly. Further, after this, when the envelope value EV ₃ is calculated (i = 3, step S25), and the envelope value EV ₃ may increase slightly.

Next, the crosstalk coefficients _{C 1, 2} and crosstalk coefficients _{C 1, 3,} envelope value EV ₂ and envelope value EV ₃ are respectively multiplied (step S28). The crosstalk coefficients C ₁ and ₂ and the crosstalk coefficients C ₁ and ₃ are “0”, and the envelope value EV ₂ and the envelope value EV ₃ are “43” and “30”. On the other hand, since the envelope value EV ₁ is “100”, the envelope value EV ₁ is larger than the multiplication result. Therefore, a musical tone is generated based on the envelope value EV ₁ and the timbre name VN ₁ (step S29), and MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). Thereby, the remaining number of hits is set to “twice”.

Next, the maximum envelope value EV _{p = 1} is selected (step S2b). In this case, since the value of index i is “1” and the value of index p is also “1”, the crosstalk coefficient is not updated (step S2c: No).

Then, until the electronic pad PD ₂ state is changed from the wait state to reject state, step S22~S2g is repeatedly executed. During this time, since it is determined as “No” in step S26, the crosstalk coefficient is not updated. During this period, the envelope value EV ₁ is not updated, but the envelope value EV ₂ and the envelope value EV ₃ are sequentially updated (i = 2 or 3, step S25).

When the electronic pad PD ₂ transitions from the wait state to the reject state (i = 2, step S26), as shown in FIG. 12C, the envelope value EV ₂ is started retained (step S27). In this example, the envelope value EV ₂ held is "45". In addition, the latest of the envelope value EV ₃ is "33". However, the envelope value EV ₃ has not yet been started retained. In other words, the envelope value EV ₃ may be updated. Therefore, after this, when the envelope value EV ₃ is calculated (i = 3, step S25), and the envelope value EV ₃ may increase slightly.

Next, the crosstalk coefficients _{C 2,1} and crosstalk coefficients _{C 2,3,} envelope values EV ₁ and envelope value EV ₃ are respectively multiplied (step S28). The crosstalk coefficient C _2,1 and the crosstalk coefficient C _2,3 are “0”. The envelope value EV ₁ is “100”, and the envelope value EV ₃ is “33”. On the other hand, since the envelope value EV ₂ is "45", than the multiplication result, a large envelope value EV _2. Therefore, based on the envelope value EV ₂ and tone name VN _2, the tone is generated (step S29), MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). In this case, a musical sound related to an electronic pad different from the hit target is generated, and MIDI data related to the musical sound is transmitted to the setting device 30. Therefore, the remaining number of hits remains “2”.

Next, the maximum envelope value EV _{p = 1} is selected (step S2B). In this case, since the value of index i is “2” while the value of index p is “1”, the ratio R (= EV ₂ / EV ₁ = 45/100 = 0.45) is calculated. (Step S2d). Then, the crosstalk coefficient C _2,1 is updated to the ratio R (= “0.45”) (step S2e).

Then, until the electronic pad PD ₃ transitions from the wait state to reject state, step S22~S2g is repeatedly executed. During this time, since it is determined as “No” in step S26, the crosstalk coefficient is not updated. During this period, the envelope value EV ₁ and the envelope value EV ₂ are not updated, but the envelope value EV ₃ is updated sequentially (i = 3, step S25).

Next, when the electronic pad PD ₃ transitions from the wait state to the reject state (i = 3, step S26), as shown in FIG. 12D, the holding of the envelope value EV ₃ is started (step S27). In this example, the envelope value EV ₃ held is "35".

Next, the crosstalk coefficient _{C 3, 1} and crosstalk coefficients _{C 3,2,} envelope values EV ₁ and envelope values EV ₂ are respectively multiplied (step S28). The crosstalk coefficient C _3,1 and the crosstalk coefficient C _3,2 are “0”. The envelope value EV ₁ is “100”, and the envelope value EV ₂ is “45”. On the other hand, since the envelope value EV ₃ is "35", than the multiplication result, a large envelope value EV _3. Therefore, a musical tone is generated based on the envelope value EV ₃ and the timbre name VN ₃ (step S29), and MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). In this case, a musical sound related to an electronic pad different from the hit target is generated, and MIDI data related to the musical sound is transmitted to the setting device 30. Therefore, the remaining number of hits remains “2”.

Next, the maximum envelope value EV _{p = 1} is selected (step S2b). In this case, since the value of index i is “3” while the value of index p is “1”, the ratio R (= EV ₃ / EV ₁ = 35/100 = 0.35) is calculated. (Step S2d). Then, the crosstalk coefficient C _2,1 is updated to “0.35” (step S2e). Next, the value of the index i is set to “1” again (steps S2g, S22, and S23). That, is selected as the electronic pad PD ₁ again processed.

In front of the second strike of the electronic pad PD _1, each electronic pad is rejected state or an idle state: so (step S26 No), the crosstalk coefficient is not updated. In addition, before the electronic pad PD ₁ is hit again, a predetermined time td has elapsed, and the envelope values EV _{1 to} EV ₃ can be updated.

When the electronic pad PD ₁ is again striking, with procedures similar during the first striking, crosstalk coefficients _{C 2,1} and _{C 3, 1} is updated. For example, when the electronic pad PD ₁ is selected as the processing target, it is assumed that the envelope value EV ₁ is “100” and the envelope value EV ₂ is “50” in step S2d. In this case, since the ratio R (= “0.5”) is larger than the crosstalk coefficient C _2,1 (= “0.45”) calculated at the time of the first hit, the crosstalk coefficient C _2,1 is It is updated (C _2,1 = “0.5”). Further, for example, when the electronic pad PD ₁ is selected as a processing target, it is assumed that the envelope value EV ₁ is “100” and the envelope value EV ₂ is “30” in step S2d. In this case, since the ratio R (= “0.30”) is smaller than the crosstalk coefficient C _2,1 (= “0.45”) calculated at the first hit, the crosstalk coefficient C _2,1 is updated. Not.

The procedure for the third hit is the same as the procedure for the second hit. When the electronic pad PD ₁ is hit three times, the setting device 30 selects the electronic pad PD ₂ as a hit target. A predetermined time td elapses before the electronic pad PD ₂ is hit, and the envelope values EV _{1 to} EV ₃ can be updated.

When the electronic pad PD ₂ is hit, the electronic pad PD ₂ starts to vibrate _first, and the electronic pad PD ₁ and the electronic pad PD ₃ begin to vibrate slightly later than the electronic pad PD ₂ . Hereinafter, an example in which the electronic pad PD ₂ , the electronic pad PD ₃ , and the electronic pad PD ₁ start to vibrate in this order will be described. In the crosstalk coefficient setting process, the electronic pads PD _{1 to} PD ₃ are sequentially (cyclically) selected, and it is determined in step S26 whether or not the currently selected pad has transitioned from the wait state to the reject state. The Therefore, if the step S26 is the timing to be executed, before the electronic pad PD ₂ to first started to vibrate, the electronic pads PD ₁ or the electronic pad PD ₂ is determined to have transitioned from the wait state to the reject state There is also. Hereinafter, an electronic pad is determined that the shift in the reject state from the first wait state, and the electronic pad PD _1. The electronic pad that is determined to have transitioned from the wait state to the reject state _second is the electronic pad PD2. The electronic pad is determined finally from wait state that the shift in the reject state, the electronic pad PD _3.

As shown in FIG. 13A, before the electronic pad PD ₁ transitions from the wait state to the reject state, the crosstalk coefficient is not updated (i = 1 to 3, step S26: No). In the meantime, the envelope values EV _{1 to} EV ₃ are sequentially updated (i = 1 to 3, step S25).

When the electronic pads PD ₁ transitions from the wait state to the reject state (i = 1, step S26), as shown in FIG. 13B, the envelope value EV ₁ is started retained (step S27). That is, in the period until a predetermined time td from the timing has elapsed, the envelope value EV ₁ is not updated. In this example, the retained envelope value EV ₁ is “45”. At this timing, the electronic pad PD ₂ and the electronic pad PD ₃ also start to vibrate and have already transitioned from the idle state to the wait state. The latest of the envelope values EV ₂ is "98". In addition, the latest of the envelope value EV ₃ is "30".

Next, the crosstalk coefficients _{C 1, 2} and crosstalk coefficients _{C 1, 3,} envelope value EV ₂ and envelope value EV ₃ are respectively multiplied (step S28). The crosstalk coefficients C ₁ and ₂ and the crosstalk coefficients C ₁ and ₃ are “0”, and the envelope value EV ₂ and the envelope value EV ₃ are “98” and “30”. On the other hand, since the envelope value EV ₁ is “45”, the envelope value EV ₁ is larger than the multiplication result. Therefore, a musical tone is generated based on the envelope value EV ₁ and the timbre name VN ₁ (step S29), and MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). In this case, a musical sound related to an electronic pad different from the hit target is generated, and MIDI data related to the musical sound is transmitted to the setting device 30. Therefore, the remaining number of hits remains “3 times”.

Next, the maximum envelope value EV _{p = 2} is selected (step S2b). In this case, since the value of index i is “1” while the value of index p is “2”, the ratio R (= EV ₂ / EV ₁ = 45/98 = 0.46) is calculated. (Step S2d). Then, the crosstalk coefficient C _2,1 is updated to the ratio R (= “0.46”) (step S2e).

Then, until the electronic pad PD ₂ transitions from the wait state to reject state, step S22~S2g is repeatedly executed. During this time, since it is determined as “No” in step S26, the crosstalk coefficient is not updated. During this period, the envelope value EV ₁ is not updated, but the envelope value EV ₂ and the envelope value EV ₃ are sequentially updated (i = 2 or 3, step S25).

When the electronic pad PD ₂ transitions from the wait state to the reject state (i = 2, step S26), as shown in FIG. 13C, the envelope value EV ₂ is started retained (step S27). In this example, the envelope value EV ₂ held is "100". In addition, the latest of the envelope value EV ₃ is "33". However, the envelope value EV ₃ has not yet been started retained. In other words, the envelope value EV ₃ may be updated. Therefore, after this, when the envelope value EV ₃ is calculated (i = 3, step S25), and the envelope value EV ₃ may increase slightly.

Next, the crosstalk coefficients _{C 2,1} and crosstalk coefficients _{C 2,3,} envelope values EV ₁ and envelope value EV ₃ are respectively multiplied (step S28). The crosstalk coefficient C _2,1 is “0.45”, and the crosstalk coefficient C _2,3 is “0”. The envelope value EV ₁ is “45”, and the envelope value EV ₃ is “33”. On the other hand, since the envelope value EV ₂ is "100", than the multiplication result, a large envelope value EV _2. Therefore, based on the envelope value EV ₂ and tone name VN _2, the tone is generated (step S29), MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). Thereby, the remaining number of hits is set to “twice”.

Next, the maximum envelope value EV _{p = 2} is selected (step S2b). In this case, since the value of the index i is “2” and the value of the index p is “2”, the crosstalk coefficient is not updated (step S2c: No).

Then, until the electronic pad PD ₃ transitions from the wait state to reject state, step S22~S2g is repeatedly executed. During this time, since it is determined as “No” in step S26, the crosstalk coefficient is not updated. During this period, the envelope value EV ₁ and the envelope value EV ₂ are not updated, but the envelope value EV ₃ is updated sequentially (i = 3, step S25).

Next, when the electronic pad PD ₃ transitions from the wait state to the reject state (i = 3, step S26), as shown in FIG. 13D, the envelope value EV ₃ is started to be held (step S27). In this example, the envelope value EV ₃ held is "35".

Next, the crosstalk coefficient _{C 3, 1} and crosstalk coefficients _{C 3,2,} envelope values EV ₁ and envelope values EV ₂ are respectively multiplied (step S28). The crosstalk coefficient C _3,1 is “0.3”, and the crosstalk coefficient C _3,2 is “0”. The envelope value EV ₁ is “45”, and the envelope value EV ₂ is “100”. On the other hand, since the envelope value EV ₃ is "35", than the multiplication result, a large envelope value EV _3. Therefore, a musical tone is generated based on the envelope value EV ₃ and the timbre name VN ₃ (step S29), and MIDI data corresponding to the musical tone is transmitted to the setting device 30 (step S2a). In this case, a musical sound related to an electronic pad different from the hit target is generated, and MIDI data related to the musical sound is transmitted to the setting device 30. Therefore, the remaining number of hits remains “2”.

Next, the maximum envelope value EV _{p = 2} is selected (step S2b). In this case, since the value of index i is “3” while the value of index p is “1”, the ratio R (= EV ₃ / EV ₂ = 35/100 = 0.35) is calculated. (Step S2d). Then, the crosstalk coefficient C _3,2 is updated to “0.35” (step S2e). Next, the value of the index i is set to “1” again (steps S2g, S22, and S23). That, is selected as the electronic pad PD ₁ again processed.

In front of the second strike of the electronic pad PD _2, each electronic pad is rejected state or an idle state: so (step S26 No), the crosstalk coefficient is not updated. Further, before the electronic pad PD ₂ is again striking, predetermined time td has elapsed, the envelope value _EV 1 _{~EV 3} is updatable.

Also in the second strike and third striking of the electronic pad PD _2, crosstalk coefficients are updated in a similar procedure to that described above. Further, even while the electronic pad PD ₃ is selected by striking a striking object, crosstalk coefficients are updated by the same procedure as the procedure described above (see FIG 14A~ Figure 14D). In the example of FIG 14A~ Figure 14D, an electronic pad is determined that the shift in the reject state from first wait state, and the electronic pad PD _2. Electronic pad is determined that transition from the wait state to reject state the second was the electronic pad PD _3. The electronic pad is determined finally from wait state that the shift in the reject state, to form an electron pad PD _1.

When the electronic pads PD _{1 to} PD ₁₂ are struck and played, the CPU 27a executes the same processing as steps S22 to S2a, and uses the crosstalk coefficient set by the above-described crosstalk coefficient setting process to perform crosstalk. Is determined (step S28), and a musical sound relating to the electronic pad determined to have been truly hit is generated (step S29).

According to the first embodiment configured as described above, an image representing the setting procedure of each parameter is displayed on the display screen of the display 32. The user, by operating the electronic pad PD _n or a touch panel 34 according to the displayed image, the parameters are set. That is, there is no possibility that the user makes a mistake in the parameter setting procedure, and therefore the user can set the parameters without delay. In particular, when setting the crosstalk coefficient, the user simply strikes the electronic pads PD _{1 to} PD ₁₂ three times in order according to the display contents of the display 32, and the musical sound generating device 20 performs the crosstalk coefficient C _{n. , M} can be set. Thus, the user can set all parameters more easily than in the past.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The configuration of the second embodiment is the same as the configuration of the first embodiment. However, a part of the crosstalk coefficient setting process executed by the musical sound generation device 20 is different from the first embodiment. Hereinafter, in the description of the second embodiment, the same reference numerals as those of the first embodiment are used for the same configurations as those of the first embodiment, and the description thereof is omitted.

In the first embodiment described above, a crosstalk coefficient is set for each crosstalk generation source. However, in the second embodiment, as shown in FIG. 15, for each electronic pad PD _{n (= 1, 2,..., 12)} , one crosstalk coefficient C _{n (= 1, 2,... ·, 12),} the source list is a list of electronic pads comprising a source of crosstalk _{L n (= 1,2, ···,} 12) and are set.

In the second embodiment, upon setting the crosstalk coefficient C _n and source list L _n, CPU 37a of the setting device 30 executes the first embodiment and the same crosstalk setting guide process (FIG. 6). On the other hand, when setting the crosstalk coefficient C _n and source list L _n, CPU 27a of the tone generation apparatus 20 executes the same processing as the crosstalk coefficient setting process in the first embodiment. However, the CPU 27a initializes the crosstalk coefficients C _{1 to} C ₁₂ and initializes the source list L _{1 to} L ₁₂ in step S21 in FIG. 10A. That is, the CPU 27a sets the crosstalk coefficients C _{1 to} C ₁₂ to “0”. Further, the generation source lists L _{1 to} L ₁₂ are set to an empty state (a state where no element of each list exists). That is, the CPU 27a sets the electronic pad PD ₁ to the electronic pad PD ₁₂ in a state where no crosstalk occurs.

Further, the CPU 27a executes steps S3e1 and S3e2 shown in FIG. 16 instead of step S2e in FIG. 11B. That is, in step S3e1, when the ratio R is larger than the crosstalk coefficient C _i calculated at the previous hit, the CPU 27a updates the crosstalk coefficient C _i to the ratio R. Further, CPU 27a in step S3e2, the source list _{L i,} to add the electronic pad PD _p. However, already if they contain electronic pad PD _p is the source list _{L i,} CPU 27a does not execute the step S3e2, the process proceeds to step S2f.

Further, CPU 27a, instead of the step S28 in FIG. 11A, as shown in FIG. 17, at step S38, the envelope value EV _j electronic pad PD _j included in the source list _{L i} crosstalk value _{C i} Multiply When all the multiplication results are larger than the envelope value EV _i , the CPU 27a determines “Yes” and proceeds to step S2f. On the other hand, when at least one of the multiplication results is equal to or less than the envelope value EV _i , the CPU 27a determines “No” and proceeds to step S29.

According to the second embodiment configured as described above, the same effect as the first embodiment can be obtained. In the second embodiment, CPU 27a, upon it determines whether crosstalk electronic pad PD _i occurs, with reference to the source list L _i, electronic pad PD that can be a source of cross-talk Perform a computation for _j only. Therefore, according to the second embodiment, the amount of calculation can be reduced.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

In the first embodiment and the second embodiment, the control device C includes the musical sound generation device 20 and the setting device 30. However, the control device C may be integrally configured. That is, the setting device 30 may be incorporated in the musical sound generation device 20. Further, tone generation apparatus 20, setting device 30, and an electronic pad _PD 1 _{-PD 12} may be configured integrally. Moreover, although the said 1st Embodiment and 2nd Embodiment are examples which applied this invention to the electronic drum set, you may apply this invention to another electronic musical instrument. For example, the present invention may be applied to a marimba-type electronic musical instrument that has a plurality of sound plates, detects vibrations of the sound plates, and generates musical sounds corresponding to the detected vibrations.

Further, CPU 27a in step S26, if the envelope value is less than a predetermined threshold value ML, electronic pad PD _n is wait state when the electronic pads PD _n have elapsed wait time WT _n from the transition to the wait state Instead of determining that the electronic pad PD _n has transitioned from the wait state to the reject state, it may be considered that the electronic pad PD _n has transitioned from the wait state to the idle state.

Further, the CPU 27a calculates the ratio R in step S2d. However, instead of this, the difference between the envelope value EV _p and the envelope value EV _i may be calculated. For example, when hitting an electronic pad PD ₁ (e.g. snare), when the vibration electronic pad PD ₂ (e.g. Tam), a value obtained by subtracting the envelope value EV ₂ from the envelope value EV ₁ as a cross-talk coefficient _{C 1, 2} You may remember. Then, when the play strikes each electronic pad PD _n, a value of the envelope value EV ₂ from the envelope value EV ₁ by subtracting is sufficiently larger than the cross-talk coefficients _{C 1, 2,} an electronic pad PD ₁ is truly striking You may make it determine with having been carried out.
