On the other hand, when the speaker interval is set wide, such as when the performance is heard by a large number of audiences with an external speaker in a wide hall, it is considered appropriate not to widen the dispersion width of the sound image. Also, in the case of headphone output, an appropriate sound image dispersion width may be different from that in the case of speaker output.

  In addition, the code | symbol in the said parenthesis is an illustration.

  According to the first aspect of the present invention, it is possible to reproduce a musical sound with a sound image setting suitable for the selected musical sound generator.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing the overall configuration of a musical tone signal output apparatus according to an embodiment of the present invention. The musical tone signal output device is configured as an electronic percussion instrument as an example.

  In this musical tone signal output device, a ROM 12, a RAM 13, a timer 14, a storage device 15, a display device 16, various interfaces 17, an operator interface 18, a tone generator circuit 19 and an effect circuit 20 are connected to the CPU 11 via the bus 10. Configured. A pad group 21, a hi-hat controller 22 operated with a foot, and a panel operator 23 are connected to the operator interface 18. The effect circuit 20 is connected to the tone generator circuit 19, and the musical sound generator 24 is connected to the effect circuit 20.

  The pad group 21 includes a plurality of pads A, pads B,. Each pad is provided with a sensor (not shown) that detects a hit, and a hit detection signal is supplied as a key-on signal to the CPU 11 via the operator interface 18. The panel operator 23 includes a plurality of switches for inputting various information. Signals generated by operations of the hi-hat controller 22 and the panel operator 23 are also supplied to the CPU 11 via the operator interface 18.

  The CPU 11 controls the entire apparatus. The ROM 12 stores a control program executed by the CPU 11 and various table data. The RAM 13 temporarily stores various input information such as performance data and text data, various flags, buffer data, and calculation results. The timer 14 is connected to the CPU 11 and measures various times such as an interrupt time in the timer interrupt process. The storage device 15 stores control programs, performance data, various data, and the like.

  The display device 16 displays various information. The various interfaces 17 include a MIDI (Musical Instrument Digital Interface) interface, a wired or wireless communication interface, and other interfaces. The tone generator circuit 19 converts performance data input from the pad group 21 and hi-hat controller 22, performance data stored in advance, and the like into musical tone signals. The effect circuit 20 gives various effects to the tone signal input from the tone generator circuit 19 and outputs it to the tone generator 24. The musical tone generator 24 converts the musical tone signal input from the effect circuit 20 into sound.

  The musical sound generator 24 includes at least a headphone 24-1, a main body speaker 24-2, a standard external speaker 24-3, and an external speaker 24-4 with a distance measuring function, all of which can generate stereo musical sounds. It is. However, as will be described later, out of these four tone generators, only one selected is actually used for tone output. The main body speaker 24-2 is built in the apparatus, but the headphones 24-1 and the external speakers 24-3, 24-4 are physically separated from the apparatus and are not used. The connection is made via the illustrated connection terminal. The number of the musical sound generating devices 24 is not limited and may be plural.

  Accordingly, only the main body speaker 24-2 of the musical sound generating device 24 is a component of the present device. The external speaker with interval measuring function 24-4 includes a distance measuring unit 25, and a left speaker 24-4L and a right speaker 24-4R that can be spaced apart from each other. The distance measuring unit 25 has a function of measuring the arrangement interval between the left speaker 24-4L and the right speaker 24-4R and displaying the measurement result or outputting the result to the apparatus or the outside. The structure of the distance measuring mechanism in the distance measuring unit 25 is not limited. For example, one of the left speaker 24-4L and the right speaker 24-4R is optically measured such as triangulation for measuring the distance from the other. It is conceivable to provide a distance measuring function. Alternatively, a distance measuring mechanism using ultrasonic waves may be used.

  It should be noted that an output unit that can output the musical sound signal generated by the present apparatus to the musical sound generating apparatus 24 to produce a stereo sound is not limited to the configuration via the effect circuit 20 and is output through a separate interface. It may be.

  Different timbres are assigned to the pads A to F of the pad group 21. The sound based on the striking operation on the pads A to F is handled as a sound of a different system, and the localization is individually set for each tone color. The initial setting of the relative relationship in sound image localization (hereinafter also simply referred to as “localization”) of the sound of each tone color is determined in advance. Specifically, in this embodiment, different sound generation channels are assigned to the respective pads A to F, and the localization is set for each sound generation channel. The sound localization corresponding to each of the pads A to F is determined by a localization table TB (described later in FIG. 3) stored in the ROM 12.

  FIGS. 2A to 2C are conceptual diagrams showing sound localization corresponding to the pads A to F as viewed from the audience side. FIG. 3 is a conceptual diagram of the localization table TB. Hereinafter, sounds corresponding to the pads A to F are abbreviated as “sounds A to F”. For example, the drum timbres assigned to the pads A to F are, in order, a ride cymbal, a tom, a bass drum, a snare drum, a crash cymbal, and a hi-hat cymbal. Note that sounds corresponding to the hi-hat controller 22 may be further added to the sounds A to F. Alternatively, the hi-hat controller 22 may correspond to any of the sounds A to F (for example, the sound C to which the bass drum is assigned) instead of the pad.

  First, the relative relationship in localization of the sounds A to F is defined by a virtual distance from one specific sound among them. In the initial setting, as shown in FIG. 2A, the localization of the sounds A to F is the sounds A, B,. Here, in a certain localization, one of the sounds localized at the center position 31C is set as a specific sound (here, the sound C). The virtual distance from the specific sound localization position to the farthest sound (sound F in this case) is set as a reference value, and this reference value is set as “shift rate ST (see FIGS. 2 and 3)”. Is set to +1.0. For the other sounds A to E, the virtual distance from the localization position of the sound C is defined by the shift rate ST having the same significance as described above. At this time, the shift rate ST is given a sign “+” on the right side of the sound C and a sign “−” on the left side. For example, the shift rate ST of the sound A is −0.8, and the shift rate ST of the sound B is −0.4 (see FIG. 2A and FIG. 3).

  Also, as shown in FIG. 2A, in the sound image localization, a dispersion width BS that defines the spread of each sound in the left-right direction is defined by a value in the range of 0 to 127, for example. The dispersion width BS is a value twice the interval from the center position 31C to the farthest sound (sound F in this case). The range from the left limit position 31L to the right limit position 31R is the maximum range in which the dispersion width BS can be expanded, and is the maximum width Bmax. The value of the dispersion width BS expanded to the maximum width Bmax is, for example, “127” as shown in FIG. In the localization setting example of FIG. 2A, the dispersion width BS of the sounds A to F is “100”, and similarly, in the localization setting examples of FIGS. 2B and 2C, “70”, “ 40 ". When the dispersion width BS is 0, all sounds are located at the center position 31C (substantially monaural). 2A to 2C, the relative relationship between the sounds A to F, that is, the respective shift rates ST are the same.

  The center position 31C is a position corresponding to the middle between the left limit position 31L and the right limit position 31R. When the center position 31C is shifted in the left-right direction (FIGS. 8D to 8F), the value of the center position 31C is a value of + or − with respect to the initial value “0”.

  As shown in FIG. 3, in the localization table TB, a center position 31C, a dispersion width BS, and a shift rate ST are defined. The center position 31C has the same value (“0”) in any of the musical tone generators 24. Regarding the dispersion width BS, values of “100”, “100”, and “70” are defined corresponding to the headphones 24-1, the main body speaker 24-2, and the standard external speaker 24-3, respectively. Further, the value of the dispersion width BS corresponding to the external speaker 24-4 with the interval measurement function varies depending on the arrangement interval between the left speaker 24-4L and the right speaker 24-4R, and is “close”, “middle”, “far”. , Values of “100”, “70”, and “40” are defined. Note that the number of levels is not limited to “near”, “middle”, and “far”, and may be a plurality of levels.

  The shift rate ST is common to all the musical sound generators 24, but individual values are set for the sounds A to F, respectively, “−0.8”, “−0.4”, The values are “0”, “+0.2”, “+0.5”, and “+1.0”. The center position 31C, the dispersion width BS, and the shift rate ST are collectively referred to as a “localization parameter”. With the localization table TB, localization parameters are set for each sound A to F as a value corresponding to one selected musical sound generator 24.

  The values in the localization table TB are all examples, and are not limited to these values including the magnitude relationship. For example, in the headphone 24-1, the dispersion width BS may be different from that of the main body speaker 24-2.

  When the headphone 24-1 or the main body speaker 24-2 is selected as the musical tone generator 24 that is actually used for musical tone output by each processing described later, the center position 31C is “0” and distributed by the localization table TB. The width BS is set to “100”, and the sound image localization as shown in FIG. Similarly, when the standard external speaker 24-3 is selected, the sound image localization is as shown in FIG. In addition, when the external speaker 24-4 with the interval measurement function is selected and the arrangement interval between the left speaker 24-4L and the right speaker 24-4R corresponds to “far”, it is shown in FIG. Sound image localization like this. Note that the initial setting (default) of the selection of the musical sound generator 24 is, for example, the standard external speaker 24-3.

  FIG. 4 is a diagram showing a flowchart of the main processing in the present embodiment. This process is started when the apparatus is turned on.

  First, initialization is executed, that is, execution of a predetermined program is started, initial values are set in various registers, and initial setting is performed (step S101). Next, it is determined whether or not the panel operator 23 is operated (panel input) (step S102). If there is no panel input, performance input by the pad group 21 and the hi-hat controller 22 is accepted (step S108). Is executed (step S109), and the process returns to step S102.

  On the other hand, if there is any panel input in step S102, if it is related to the sound image localization change, the sound image localization change process of FIG. 7 described later is executed (steps S103 and S104), and the process proceeds to step S108. Return. If the panel input relates to the tone generator setting, the tone generator setting process of FIG. 5 described later is executed (steps S105 and S106), and the process returns to step S108. If the panel input is another instruction not related to the sound image localization change or the tone generator setting, the other input instruction is executed (step S107), and the process returns to step S108.

  FIG. 5 is a flowchart of the tone generation unit setting process executed in step S106 of FIG. First, on the display device 16 (refer to FIG. 1), selection items for all four types of musical sound generating devices 24 are displayed as menu displays (step S201), and one musical sound generating device used for musical sound output is selected or changed. Is received (step S202). The user selects one of the displayed items.

  Next, only when the external speaker 24-4 with the interval measurement function is selected, the input of the value of the arrangement interval between the left speaker 24-4L and the right speaker 24-4R is accepted (step S204). For example, the user grasps the value of the measurement result of the arrangement interval displayed in the distance measuring unit 25 and manually inputs it using the panel operation element 23. Next, the process proceeds to step S205. Also when other than the external speaker 24-4 with the interval measurement function is selected, the process proceeds to step S205.

  In step S205, the localization parameter corresponding to the musical tone generator 24 selected in step S202 is determined for each sound A to F, that is, for each tone color, based on the localization table TB (FIG. 3). The process ends. At that time, in the case where the external speaker 24-4 with the interval measuring function is selected, depending on whether the value of the input arrangement interval corresponds to “near”, “middle”, or “far”. Then, the dispersion width BS is determined (see FIG. 3).

  In this process, if the musical tone generator 24 to be selected is changed, the localization parameter corresponding to the musical tone generator 24 is set in step S205, but the shift rate ST is common to all musical tone generators 24. (See FIG. 3), the relative relationship in localization of the sounds A to F is maintained.

  FIG. 6 is a flowchart of the sound generation process executed in step S109 of FIG. First, it is determined whether or not automatic performance is being executed (step S301). The automatic performance is a process of accepting music selection of automatic performance data such as MIDI data, which has been taken in from the outside or stored in advance in the ROM 12 or the storage device 15, and performs automatic reproduction according to the automatic performance data. The panel operator 23 accepts instructions regarding automatic performance. In the present embodiment, the automatic performance data is mainly assumed to be sound data of drum instrument sounds corresponding to the sounds A to F. Note that the musical sound can be generated by the manual performance operation of the pad group 21 and the hi-hat controller 22 even when the automatic performance is being executed.

  If the automatic performance is being executed in step S301, the automatic performance data to be reproduced is read and the sound generation timing based on the read sound data is checked (step S303). When the sounding timing of the read sounding data comes (step S304), the process proceeds to step S305.

  On the other hand, if the automatic performance is not being executed in step S301, it is determined whether there is a key-on, that is, whether the pad group 21 or the hi-hat controller 22 has been operated (step S302). finish. If there is a key-on, the process proceeds to step S305. The sound generation timing and the key-on during automatic performance execution correspond to the reception of the sound generation instruction.

  In step S305, the sound generation instruction channel is grasped. That is, the sound generation channel corresponding to the read sound generation data or the pad group 21 to the hi-hat controller 22 that has been operated is grasped. Next, the velocity and localization parameters of the sound to be generated are grasped (step S306). Here, the velocity is grasped from the sound production data in the automatic performance, and is grasped from the detection result of the performance operation in the case of the key-on. The localization parameters determined in step S205 in FIG. If step S205 is not executed at the stage of this process, the localization parameter is set to an initial setting value.

  Next, the information on the grasped velocity and localization parameters is transmitted to the tone generator circuit 19, and the tone generator circuit 19 generates a musical sound signal (step S307). This musical tone signal is a musical tone signal in which each sound A to F is generated with sound image localization according to the localization parameter. Then, the generated musical sound signal is output to the musical sound generating device 24 via the effect circuit 20 (step S308), and this process is terminated. As a result, sound is generated from the selected musical sound generator 24 with sound image localization corresponding to the musical sound generator 24.

  As described above, the localization parameters are basically determined by the localization table TB. As described with reference to FIGS. 7 and 8, the center position 31C, the dispersion width BS, and the shift rate ST are changed individually afterwards. It is possible.

  FIG. 7 is a flowchart of the sound image localization changing process executed in step S104 of FIG. First, it is determined whether or not the sound image localization change designation in step S103 in FIG. 4 is a designation to change any shift rate ST of the sounds A to F (step S401). If so, the target designation is accepted (step S402). That is, the designation of the sound to be changed is accepted. Next, the current value of the designated sound shift rate ST is displayed on the display device 16 (step S403), and a change in the shift rate ST is accepted (step S404). Then, the shift rate ST of the designated sound is updated to the set value after the change (step S405), and this process ends.

  On the other hand, if the sound image localization change designation is not individual designation, it is determined whether or not the dispersion width BS is designated (step S406). If so, the current value of the dispersion width BS is displayed on the display device 16 (step S407), the change of the dispersion width BS is accepted (step S408), and the dispersion width BS is updated to the changed set value ( Step S409), the process is terminated.

  If the sound image localization change designation is neither the shift rate ST nor the dispersion width BS, it is determined whether or not the center position 31C is designated for change (shift) (step S410). If so, the current value of the center position 31C is displayed on the display device 16 (step S411), the change of the center position 31C is accepted (step S412), and the center position 31C is updated to the set value after the change ( Step S413), the process is terminated.

  If the sound image localization change designation is any other designation that is not any change designation of the shift rate ST, the dispersion width BS, or the center position 31C, the setting is performed according to the other designation (step S414), and this process is terminated. .

  8A to 8C are conceptual diagrams showing the localization of the sounds A to F when the dispersion width BS is changed. 8D to 8F are conceptual diagrams showing the localization of the sounds A to F when the center position 31C is changed. In particular, FIGS. 8C and 8F are modified examples.

  First, for the dispersion width BS changed in steps S406 to S409 in FIG. 7, when the dispersion width BS is narrowed (for example, about BS value = 25), as shown in FIG. Will concentrate. If the dispersion width BS is further narrowed, it will be as close to monaural as possible. Conversely, when the dispersion width BS is widened and the BS value is changed to 127, the sound F is located at the right limit position 31R as shown in FIG. 8B. As described above, in the present embodiment, the maximum BS value that can be set is 127, and the localization cannot be further increased.

  However, the dispersion width BS may be configured to be set to exceed 127. For example, when the dispersion width BS exceeds 127, as shown in FIG. 8C, the sound that has reached the right limit position 31R or the left limit position 31L is fixed (sticked) to that position. . However, sounds that have not yet reached the right limit position 31R or the left limit position 31L and have room for movement are displaced outward in the left-right direction as the dispersion width BS increases. In this modification, after the dispersion width BS exceeds 127, the shift rate ST is not maintained as set.

  Note that the localization position of each sound after the dispersion width BS exceeds 127 may be adjusted separately on the left side and the right side of the center position 31C. For example, when there is a sound stuck to the right limit position 31R and there is no sound that has reached the left limit position 31L, only the left sound is further leftward in accordance with the increase in the dispersion width BS. Try to be displaced.

  On the other hand, for the center position 31C changed in steps S410 to S413 in FIG. 7, for example, when the value is changed from “0” to “+20”, as shown in FIG. The whole is displaced to the right by “+20” while maintaining the relative relationship with each other. Although the center position 31C can be further increased in the + direction, in the present embodiment, as shown in FIG. 8 (e), the sound F reaches a right limit position 31R and beyond. The center position 31C cannot be changed to a large value in the + direction.

  However, the center position 31C may be configured to be set to a value that can be changed in the same direction even when any sound reaches the right limit position 31R or the left limit position 31L. For example, as shown in FIG. 8F, by changing the center position 31C, the sound that has reached the right limit position 31R or the left limit position 31L is fixed at that position. However, sounds that have not yet reached the right limit position 31R or the left limit position 31L and have room for movement are displaced according to the change in the center position 31C. In this modification, after a certain sound reaches the right limit position 31R or the left limit position 31L, the shift rate ST is not maintained as set.

  Although the sound image localization by the individual change of the shift rate ST (steps S401 to S405 in FIG. 7) is not shown, naturally, the relative relationship between the sounds changes. Further, as a result of the individual change of the shift rate ST, when any sound is instructed to protrude from the right limit position 31R or the left limit position 31L, the dispersion width BS is automatically reduced, or It is assumed that the center position 31C is automatically corrected in a direction to avoid it.

  According to the present embodiment, when one of the tone generators 24 is selected, the sound image localization of each of a plurality of sounds is determined according to the tone generator 24 based on the dispersion width BS of the localization table TB. It is set while maintaining the relative relationship. As a result, the musical sound can be reproduced with the sound image setting suitable for the selected musical sound generating device.

  In particular, when the external speaker 24-4 with the interval measurement function is selected, the sound image localization is set according to the arrangement interval between the left speaker 24-4L and the right speaker 24-4R. Musical sound reproduction can be performed with a sound image setting suitable for the interval.

  Note that the shift rate ST based on the localization position of the sound C is used as information defining the relative relationship in sound image localization of the sounds A to F corresponding to the pads A to F (see FIGS. 2 and 3). Not limited to this. For example, it may be information on a set of values individually indicating the absolute localization position of each sound in the default dispersion width BS. Alternatively, from the viewpoint of simplifying the configuration, it may be information that defines only the arrangement order of the sounds A to F.

  In addition, although the distribution width information that is the spread in the left-right direction in sound image localization of a plurality of sound systems is the distribution width BS in the present embodiment, it is not limited thereto. For example, it may be expressed as a ratio to the value of the dispersion width set for a predetermined musical sound generator 24 (for example, the standard external speaker 24-3) in the localization table TB. Alternatively, it may be expressed by some mathematical formula or function. Further, the location where the distribution width information is held is not limited to the ROM 12 and may be any location accessible by the CPU 11.

  In the localization table TB, with respect to the shift rate ST, only a part of the tone generators 24 (for example, the headphones 24-1) are excluded from the subject of the present invention, and the shift rate ST of the other tone generators 24 is excluded. The value may be different from the one.

  Note that the sounds A to F whose localization is set individually may be configured to have different sound generation systems, and may be distinguished by channels, timbres, controls, tracks, etc., and can be controlled individually. That's fine.

  Further, in the present embodiment, an electronic percussion instrument is exemplified as the musical tone signal output device and includes the pad group 21 and the hi-hat controller 22 that are performance operators, but the device configuration as a trigger module does not include these. It is good. In that case, a performance operation signal from the performance operator is input, and a musical sound signal is generated and output.

  Note that the sound image localization may be controlled not only by volume control but also by delay.

  In the present embodiment, the drum sound has been described as an example, but the present invention is not limited to this. For example, in an electronic musical instrument that can generate a plurality of timbres, a channel is associated with each timbre, and sound image localization may be set individually for each channel. Also, when applied to keyboard instruments, even in a mode where the timbres that sound at the same time are the same, the sound range is divided into multiple parts, each channel corresponds to a different channel, and the sound image localization is set individually for each channel. Also good.

  In step S202 of FIG. 5, one musical sound generating device used for musical sound output is manually set by the user through an input operation, but may be configured to be automatically set. In that case, the configuration is as follows. Each of the musical tone generators 24 holds identification information for identifying itself. The musical tone generator 24 and the musical tone signal output device, excluding the main body speaker 24-2, can be physically and electrically connected and disconnected by an interface capable of data communication (for example, one of the various interfaces 17). Configure. When the musical tone generator 24 is connected alternatively, the identification information is automatically transmitted from the musical tone generator 24 to the musical tone signal output device. In this musical tone signal output device, the musical tone generating device 24 is grasped from the received and acquired identification information, and the grasped one is handled as the selected musical tone generating device 24.

  Further, in step S204 of FIG. 5, the user manually sets the value of the arrangement interval between the left speaker 24-4L and the right speaker 24-4R of the external speaker 24-4 with the interval measurement function by an input operation. However, this may be automatically input. In that case, the configuration is as follows. The external speaker 24-4 with interval measurement function and the musical tone signal output device are configured to be physically and electrically connected and disconnected by an interface capable of data communication (for example, one of the various interfaces 17). To do. When the external speaker 24-4 with interval measurement function is connected, distance measurement by the distance measurement unit 25 is automatically executed, and the measurement result is transmitted to the musical tone signal output device.

  The arrangement interval measuring function may be provided in the musical tone signal output apparatus.
