Description

TECHNICAL FIELD

[0001] The present application relates to an electronic wind instrument and a control method thereof. BACKGROUND

[0002] There is known an electronic wind instrument which detects a flow of air blown by a player using a breath sensor, and performs generation of a musical sound signal or control of a volume in accordance with a flow rate of the detected breath. In a general electronic wind instrument, the volume is controlled by the flow rate of the breath, and the pitch is controlled by a performance operation element.

[0003] On the other hand, in order to reduce the labor of the player, there is a desire to omit the breath to perform the sound production. As an invention corresponding to the desire, there is disclosed an electronic wind instrument which can hold an output signal of a breath sensor, for example, in Patent Document 1. In the electronic wind instrument, a hold switch is pressed during the sound production, and thus the sound production state can be maintained.

[0006] [Patent Document 1] Japanese Patent Laid-Open No. 60-004994 SUMMARY

[0007] [Problems to be Solved by the Invention]

[0008] According to the invention described in Patent Document 1, the output signal of the breath sensor can be held, and thus even if the breath is not performed, the continuous sound production can be performed during the period in which the hold function is effective.

[0009] However, the invention is only an invention which holds the output of the breath sensor, and thus the breath is required to start the sound production. In addition, in a case where the hold is desired to be released, the operation of making the hold switch off is required, and there is a problem that the operation becomes complicated.

[0010] The present application is an invention which is formed in consideration of the problem, and an object thereof is to provide an electronic wind instrument in which the necessity or non-necessity of the breath can be switched by a simple operation.

[0011] [Technical Means to Solve the Problems]

[0012] The electronic wind instrument of the present application includes: an acquisition section that acquires an operation performed on a performance operation element; a breath detection section that detects a breath; and a control section that generates a musical sound signal in accordance with at least one of the detected breath and the operation acquired by the acquisition section; the control section switches a first mode in which the detection of the breath is a condition for generating a musical sound signal and a second mode in which a musical sound signal is generated based on the operation regardless of whether or not the breath is detected, in accordance with a result of the detection of the breath.

[0013] The breath is the blowing and inhaling of breath performed by a player.

[0014] The first mode is a performance mode in which the detection of the breath is a necessary condition for generating a musical sound signal. In the first mode, a musical sound signal is generated and output at a volume corresponding to the flow rate of the detected breath, and if the breath stops, the output of the musical sound signal also stops. The second mode is a performance mode in which the detection of the breath is not a necessary condition, and a musical sound signal is generated in accordance with an operation performed on a performance operation element. In the second mode (also referred to as a hold mode), a musical sound signal is generated at a pitch specified by a performance operation element regardless of whether or not the breath is present.

[0015] The control section can switch the first mode (normal mode) and the second mode (hold mode) from each other in accordance with a result of the detection of the breath, such as whether or not the breath is blown in for a prescribed time, whether or not the breath is inhaled, and the like. By being configured in such a manner that the mode can be switched using the breath as a trigger, the mode can be freely switched while the instrument is being held with both hands, that is, in a state in which a performance posture has been assumed.

[0016] In addition, the control section of the electronic wind instrument of the present application switches the mode to the first mode when the current mode is the second mode and the breath detection section detects the breath.

[0017] When the player wishes to produce a sound by the breath, the first mode is entered by performing the breath. Thus, the mode can be immediately switched. After the transition to the first mode, a sound is produced in accordance with the flow rate of the breath, and thus the performance can be smoothly continued.

[0018] In addition, the control section of the electronic wind instrument of the present application switches the mode to the second mode when the current mode is the first mode and the state in which the breath is not detected by the breath detection section continues for a prescribed time or more.

[0019] In this way, in the case where the breath is not performed for a prescribed time or more, the performance mode in which the breath is not a necessary condition can be entered. Even in this case, when the player wishes to produce a sound by the breath, the first mode is immediately entered by performing the breath. That is, the transition between modes can be performed without interfering with the intention of the player.

[0020] Further, the control means of the electronic wind instrument of the present application switches the mode to the second mode when the detected breath is in accordance with the first pattern during the first mode, and switches the mode to the first mode when the detected breath is in accordance with the second pattern during the second mode.

[0021] Thus, the mode switching can also be instructed according to the pattern of breath. The pattern can be defined by the number of times of blowing or inhaling, the number of seconds of stopping, a combination thereof, or the like.

[0022] Further, the control means of the electronic wind instrument of the present application sets the volume of the tone signal in the second mode according to the flow rate of the detected breath during the first mode.

[0023] Thus, the volume in the holding mode can also be set according to the flow rate of breath before the transition to the holding mode. According to the configuration, the performance can be performed at an appropriate volume corresponding to the environment.

[0024] The control method of the electronic wind instrument of the present application is a control method of an electronic wind instrument having a performance operation element and a breath sensor, and includes: an acquisition step of acquiring an operation on the performance operation element; a breath detection step of detecting a breath; and a control step of generating a tone signal according to at least one of the detected breath and the operation acquired in the acquisition step. In the control step, a first mode of generating a tone signal with the detection of the breath as a condition, and a second mode of generating a tone signal based on the operation regardless of the detection of the breath are switched according to the detection result of the breath.

[0025] Further, the present application can be specifically an electronic wind instrument including at least a part of the components. Further, it can be specifically a control method of the electronic wind instrument. Further, it can be specifically a program for executing the control method. The processes or components can be freely combined to be implemented as long as no technical contradiction is caused. BRIEF DESCRIPTION OF DRAWINGS

[0040] The electronic wind instrument of the present embodiment is an apparatus (electronic musical instrument) that has a built-in sound source, generates a tone signal in accordance with the breath of a performer and the operation of a performance operation element, and outputs the tone signal in the form of sound.

[0041] Figure 1 is an external view of the electronic wind instrument 100 of the present embodiment.

[0042] The electronic wind instrument 100 of the present embodiment is an electronic musical instrument that simulates a wind instrument. Specifically, it has a mouthpiece with a built-in breath sensor, a performance operation element, and a unit that generates a tone signal in accordance with the breath of a performer and the operation of a performance operation element, for example, a tone signal with the tone color of a wind instrument such as a saxophone, a trumpet, or a flute, and emits sound from a speaker.

[0043] In the prior art electronic wind instrument, a structure that determines the volume of a tone signal in accordance with the flow rate or pressure of the breath of a performer is generally adopted. In addition, there are products that enable a holding function (a function that simulates the continuation of a breath) in accordance with a prescribed operation. The holding function can be realized, for example, by storing the breath pressure at the instant when a holding button is pressed, and generating a tone signal as if the breath continues at the pressure.

[0044] However, if the configuration in which the on / off of the hold function is switched by the button operation is adopted, the operation becomes complicated. The musical instrument is played by fingering with both hands, and thus it is preferable that the operation not directly related to the performance is not performed using the fingers. The electronic wind instrument 100 of the present embodiment switches the on / off of the hold function only based on the breath, and thus solves the problem.

[0045] Reference Figure 2 The hardware configuration of the electronic wind instrument 100 will be described.

[0046] The electronic wind instrument 100 includes a control section 101, a breath detector 102, a storage device 103, a setting operation element 104, a performance operation element 105, and an output section 106. These components are driven by the power supplied from a battery.

[0047] The control section 101 is an arithmetic device that governs the control performed by the electronic wind instrument 100. The control section 101 includes, for example, a central processing unit (CPU) or the like.

[0048] The breath detector 102 is a component that detects the breath of the performer. The breath detector 102 includes a sensor that detects the flow rate of the air blown in and outputs an electric signal of the voltage corresponding to the detection result, and an analog / digital (A / D) converter that converts the electric signal into a digital signal. In addition, the detection of the breath can be performed by measuring the flow rate of the air per unit time, or can be performed by measuring the air pressure. For example, the air pressure in the mouthpiece can be sensed, and thus the flow rate of the breath can be indirectly acquired.

[0049] The storage device 103 includes a rewritable nonvolatile memory (random access memory (RAM)). In the storage device 103, a control program executed in the CPU 101 or data used by the control program is stored. The program stored in the storage device 103 is loaded and executed by the control section 101, and thus the processes described later are performed.

[0050] In addition, in the present example, the combination of the CPU and the RAM is exemplified, but all or a part of the functions illustrated can be executed using a dedicated circuit designed. In addition, the storage or execution of the program can be performed by a combination of a main storage device and an auxiliary storage device other than those illustrated.

[0051] The setting operation element 104 is an interface for setting a parameter or the like for playing. The setting operation element 104 is configured of, for example, a switch or the like for setting a tone color, a master volume, a transposition, a chorus level, a reverb level, or the like. Hereinafter, the information set by the setting operation element 104 is referred to as a tone parameter.

[0052] The playing operation element 105 is an interface for designating a pitch of a tone signal. The playing operation element 105 is configured of, for example, a plurality of keys arranged in accordance with a key arrangement of a clarinet. Hereinafter, the operation performed by the playing operation element 105 (i.e., a key pressing operation for designating a pitch) is referred to as a playing operation.

[0053] The output section 106 is a section that outputs a tone signal generated by the control section 101. Specifically, the output section 106 is configured of a digital / analog (D / A) converter, an amplifier, a speaker, or the like.

[0054] Next, the processing performed by the control section 101 is described.

[0055] Figure 3 is a diagram that represents the processing performed by the control section 101 possessed by the electronic wind instrument 100, using functional blocks. The control section 101 has a tone decision section 1011, a tone generation section 1012, and a mode selection section 1013 as functional blocks.

[0056] The tone decision section 1011 decides a tone that should be generated, in accordance with the operation performed by the player. Specifically, the tone decision section 1011 decides a tone color, a scale, a volume, or the like of a tone that should be sounded, in accordance with (1) a flow rate of breath acquired by the breath detector 102, (2) a content of the playing operation acquired by the playing operation element 105 (which key has been pressed), (3) a content of the tone parameter set by the setting operation element 104, or the like.

[0057] The content decided by the tone decision section 1011 is transmitted to the tone generation section 1012. The communication between the tone decision section 1011 and the tone generation section 1012 can also be performed through a Musical Instrument Digital Interface (MIDI) interface. In this case, control information (a note-on signal, a note-off signal, a control change, a program change, or the like) in accordance with the MIDI specification can also be transmitted and received between the tone decision section 1011 and the tone generation section 1012. In the following description, a form using the MIDI interface is exemplified.

[0058] The tone decision section 1011 operates in accordance with a mode designated by the mode selection section 1013 described later. Specifically, it operates in either of a first mode that generates a tone signal in accordance with both the breath and the performance operation, and a second mode that omits the breath and generates a tone signal in accordance with only the performance operation.

[0059] In a case where the first mode is designated as the operation mode, the tone decision section 1011 sends control information to the tone generation section 1012 to generate a tone of a pitch corresponding to the performance operation with a volume corresponding to the breath flow.

[0060] In a case where the second mode is designated as the operation mode, the tone decision section 1011 sends control information to the tone generation section 1012 to generate a tone of a pitch corresponding to the performance operation with a prescribed volume.

[0061] In addition, in the first mode, the tone decision section 1011 generates a note-on signal in a case where the breath flow exceeds a prescribed value, and generates a note-off signal in a case where the breath flow is lower than the prescribed value. On the other hand, in the second mode, the tone decision section 1011 generates a note-on signal in a case where at least any of the plurality of keys possessed by the performance operation element 105 has been pressed, and generates a note-off signal in a case where the key that has been pressed is released.

[0062] The tone generation section 1012 synthesizes a tone signal by software processing in accordance with the control information (MIDI information) that has been received from the tone decision section 1011, and outputs it toward the output section 106. In addition, the tone generation section 1012 can generate a tone signal by software processing alone, or can generate a tone signal using a tone source that includes hardware.

[0063] The mode selection section 1013 selects either of the first mode and the second mode in accordance with the presence or absence of the breath acquired by the breath detector 102. Specifically, it determines which of the first mode and the second mode to operate with, and instructs the tone decision section 1011, in accordance with the result of detecting the presence or absence of the breath within a prescribed period.

[0064] In addition, in the present embodiment, the mode is switched in accordance with the presence or absence of the breath, but it can be fixed. For example, in a case where the user has performed an operation of the intention to fix the mode via the setting operation element 104, the mode selection section 1013 can also fix the mode to either of the first mode and the second mode in accordance with the operation.

[0065] Next, the operation shown in Fig. 6 will be described. Figure 4 The flowchart of the processing performed by the tone decision section 1011 will be described. Figure 4 The operation shown in Fig. 6 starts at the timing when the power of the musical instrument is turned on.

[0066] First, in step Sll, control information to be sent to the tone generator 1012 is generated in accordance with the tone parameters set via the setting operation element 104. In this step, control information (e.g., program change or control change) that specifies tone color or effects (chorus, reverb, etc.) or the like is generated. In addition, in the case where the tone parameters have not changed from the previous processing, this step can be omitted.

[0067] Second, in step S12, the pitch of the tone to be sounded is decided in accordance with the operation (performance operation) performed by the performer on the performance operation element 105. The conversion from the performance operation to the pitch is preferably performed in accordance with the rules of an actual wind instrument. For example, the pitch can be decided in accordance with the key operation of a clarinet.

[0068] In addition, in the case where the electronic wind instrument 100 is a transposing instrument such as a saxophone and the transposition has been specified by the performer, the pitch of the tone can also be changed in this step. For example, the alto saxophone or the baritone saxophone is a pipe, and the soprano saxophone or the tenor saxophone is a pipe, but the transposition can be easily performed in the electronic instrument. In this case, the transposition can also be performed in accordance with a prescribed rule (combination of the transposition source and the transposition object).

[0069] Third, in step S13, the specified mode is determined. Here, in the case where the first mode has been specified by the mode selection section 1013, the processing moves on to step S14.

[0070] In step S14, the flow rate of the breath being performed by the performer is acquired from the breath detector 102, and control information that specifies the volume of the tone is generated in accordance with the flow rate. The conversion from the flow rate (absolute value) to the volume can be performed, for example, by referring to a table or a mathematical expression that has been stored in advance.

[0071] Fourth, in step S15, it is determined whether a breath event has occurred. The breath event refers to an event that occurs in the case where there is a change from a state in which the breath is being performed to a state in which the breath is not being performed, and a change from a state in which the breath is not being performed to a state in which the breath is being performed. Here, in the case where it is determined that the breath has started, a note-on signal is generated in step S16. In addition, in the case where it is determined that the breath has ended, a note-off signal is generated in step S16. Whether the breath is being performed can be determined by comparing the breath flow rate that has been acquired from the breath detector 102 with a prescribed threshold. In addition, when the note-on signal generated in step S16 is accompanied by the specification of the volume, the volume can also be decided in accordance with the breath flow rate.

[0072] In the case where no breath event is generated, the process is migrated to step S19.

[0073] In step S13, in the case where the second mode is designated by the mode selection section 1013, the process is migrated to step S17.

[0074] In step S17, control information that sets the volume of the tone to a prescribed value is generated. The prescribed value can be set to a value that is set in advance by the player, for example. The second mode is a mode in which the tone is produced without relying on the breath, and thus it is preferable that the volume desired by the player can be set in advance.

[0075] Next, in step S18, it is determined whether a key event has been generated. The key event is an event that is generated in the case where there is an operation of pressing a key of the performance operation element and an operation of releasing the key. Here, in the case where it is determined that the key has been pressed, the process is migrated to step S16, and a note-on signal is generated. In addition, in the case where it is determined that the key has been released, a note-off signal is generated in step S16.

[0076] In the case where no key event is generated, the process is migrated to step S19.

[0077] In step S19, the control information that has been generated is sent to the tone generation section 1012. Specifically, the control information that is generated in step S11, the control information that specifies the volume that is decided in step S14 and step S17, and the note-on signal / note-off signal that is generated in step S16 are sent. As a result, a tone signal is generated by the tone generation section 1012.

[0078] Next, the operation shown in Fig. 6 is performed. Figure 5 The flowchart of the process performed by the mode selection section 1013 will be described. Figure 5 The operation shown in Fig. 6 is started at the timing when the power of the musical instrument is turned on.

[0079] First, in step S21, the tone decision section 1011 is instructed to shift to the first mode.

[0080] Next, in step S22, the time during which no breath is taken is calculated from the information that has been acquired from the breath detector 102. A counter is incremented every prescribed time, and is reset at the timing when a breath has been detected. For example, in the case where the prescribed time is one second, the counter becomes the number of seconds during which no breath is taken.

[0081] Next, in step S23, it is determined whether the time during which no breath is taken has passed a prescribed time (for example, five seconds). When an affirmative determination is made in step S23, the process is migrated to step S24. When a negative determination is made, the process is returned to step S22, and the calculation is continued.

[0082] When the affirmative determination is made in step S23, that is, when it is determined that breathing has not been performed for the prescribed time or more, the sound determining section 1011 is instructed to shift to the second mode in step S24.

[0083] In step S25, it is determined whether breathing has been performed by the player based on the information that has been acquired from the breath detector 102. Here, in the case where breathing has been detected (step S26 - Yes), the process returns to step S21, and the sound determining section 1011 is instructed to shift to the first mode. In the case where breathing has not been detected, the process returns to step S25, and the second mode is continued.

[0084] As explained above, in the case where breathing has not been performed for the prescribed time or more, the electronic wind instrument of the present embodiment shifts to a mode in which breathing can be omitted to perform sound, and in the case where breathing has been detected, the electronic wind instrument of the present embodiment shifts to the original mode (a mode in which breathing is required to perform sound).

[0085] According to the above-described structure, mode change can be performed without performing switch or key operation. That is, mode change can be performed in a state in which the instrument is held with both hands, and thus the convenience of the player is greatly improved.

[0086] (Second Embodiment)

[0087] In the first embodiment, in steps S22 to S23, it is determined that there is no breathing for the prescribed time or more, and the determination is used as a trigger to shift to the second mode. In contrast to this, the second embodiment is an embodiment in which breathing is also used as a trigger to shift to the second mode.

[0088] The hardware structure and the component structure of the electronic wind instrument 100 in the second embodiment are the same as those of the first embodiment, and thus detailed explanation is omitted, and only the different points are explained.

[0089] Figure 6 This is a flowchart of the process performed by the mode selecting section 1013 in the second embodiment. In the second embodiment, in step S22A, the flow rate change (change in flow rate with respect to elapsed time) of the breathing that has been performed in a prescribed period is acquired. In addition, in step S23A, it is determined whether the acquired flow rate change of the breathing coincides with a first pattern. In addition, the pattern in the present embodiment can be any pattern as long as it is a pattern that indicates the time series change of the flow rate of breathing. For example, it can be "blow once", "blow twice in succession", "inhale once", and the like. Here, in the case where the acquired pattern coincides with the first pattern, the process shifts to step S24.

[0090] Further, in step S25A, the flow rate variation of the breath performed within a prescribed period is also acquired. In step S26A, it is determined whether the acquired flow rate variation of the breath is in accordance with the second pattern. Here, in the case where the acquired pattern is in accordance with the second pattern, the process moves toward step S21. The first pattern and the second pattern can be the same pattern, or can be different patterns. For example, the second pattern can be the same "blow once" pattern as in the first embodiment, and the first pattern can be a pattern such as "blow twice in succession".

[0091] In the second embodiment, the action is performed by breathing as described, whereby the switching between the first mode and the second mode is performed. According to this configuration, the player's convenience is improved since the transition to the second mode can be made without waiting for the prescribed time to elapse.

[0092] (Third Embodiment)

[0093] In the first embodiment, the volume in the second mode is set to a prescribed value as explained in step S17. In contrast, the third embodiment is an embodiment in which the volume after the transition to the second mode is decided in accordance with the flow rate of the breath performed during the period in the first mode.

[0094] In the third embodiment, the sound volume deciding section 1011 decides the volume in the second mode in accordance with the flow rate of the breath performed during the period in the first mode (for example, the flow rate of the breath acquired in step S14). The volume can be, for example, the value immediately before the transition to the second mode, or can be a representative value (for example, the average value or the maximum value) in the first mode. For example, the representative value of the volume can be decided during the period of the performance in the first mode and temporarily stored, and after the transition to the second mode, the representative value can be set as the volume in step S17.

[0095] According to the third embodiment, after the transition to the second mode, it is also possible to continue the performance of the musical instrument at an appropriate volume corresponding to the performance environment.

[0096] (Modified Example)

[0097] The embodiments described above are merely examples, and the present application can be implemented with appropriate modifications within the scope of the gist thereof.

[0098] For example, in the explanation of the embodiments, as the conditions for performing the transition between the modes, the conditions of "performing the breath", "not performing the breath for a prescribed time", "performing the breath in accordance with a prescribed pattern", and the like are exemplified, but as long as the conditions are ones that the player can express by the breath, conditions other than the exemplified conditions can also be used as triggers to perform the transition between the modes.

[0099] In addition, in the description of the embodiments, an electronic musical instrument that imitates a wind instrument such as a clarinet, a saxophone, a trumpet, a flute, or the like is exemplified, but an embodiment as an electronic musical instrument other than a wind instrument can also be considered. For example, it can also be a keyboard accordion, or an accordion, or the like. In addition, it can also be implemented as an electronic musical instrument that outputs a sound that a user has sampled, or a sound that is processed from the sound. In this case, the electronic musical instrument makes a sound in accordance with breathing, but does not need to be an electronic musical instrument that imitates a wind instrument.

[0100] Further, in the description of the embodiments, an example in which a musical sound signal is generated in accordance with breathing is exemplified, but as long as it is an operation other than with a finger, breathing can also be replaced with another operation. For example, the breath detector 102 can also be replaced with a sound detector, and a musical sound signal can be generated in accordance with the size of a sound that has been detected. In this way, an embodiment in which a vocoder element is introduced can also be considered.

[0101] Further, in a case where a switch of a mode is generated, prescribed control information can also be transmitted from the musical sound decision section 1011 to the musical sound generation section 1012. For example, in a case where a transition from the first mode to the second mode is generated, control information in which a switch from the first tone color to the second tone color is generated can also be generated and transmitted. The same also applies in reverse. According to the structure, a musical sound that is appropriate for each mode can be generated.
