Description

  The present invention relates to an electronic musical instrument capable of listening to a performance sound by selecting either a speaker or an ear-mounted sound transmitter.

  2. Description of the Related Art Conventionally, electronic musical instruments that can listen to a performance sound by selecting either a speaker or an ear-mounted sound transmitter are known. For example, the user can usually listen to the performance sound through a speaker, but if the headphone as an ear-mounted sound transmitter is connected to the headphone terminal of a piano as an electronic musical instrument, the user can hear the performance sound through the headphone. At that time, generally, the sound generation tone color is the same between the speaker sound generation and the headphone sound generation, and even when the headphones are attached, the sound is generated with the sound color selected in the device setting.

  On the other hand, there is known an instrument that employs a binaural sampling method that provides a realistic feeling as if the sound naturally resonates from the piano body even when listening through headphones (Non-Patent Document 1 below). This instrument reproduces a three-dimensional and natural sound that is less fatigued by listening by using a timbre created by recording a piano sound as it is by placing a microphone at the same position as the player's ear. In addition, a musical instrument having a function called a stereophonic optimizer that gives a natural listening effect such as a sound from a piano body when headphones are worn is also known (Non-Patent Document 2 below).

  However, the musical instrument of Non-Patent Document 1 is intended for a specific piano tone called CFX (registered trademark), and is a technique related to optimizing the sound generation when a headphone of a piano equipped with a tone other than CFX is installed. is not. Further, the instrument of Non-Patent Document 2 is provided with a uniform effect regardless of the selected timbre, and depending on the selected timbre, there may be cases where it is not appropriate to apply the effect by the stereophonic optimizer. Therefore, there is room for improvement in listening to a sound more suitable for the selected tone when using an ear-mounted sound transmitter such as headphones.

  An apparatus that switches to an alternative timbre when a sound with a specified timbre cannot be generated is also known. However, in this type of apparatus, normally, when a sound with a specified tone color can be generated, the specified tone color is generated. Also, there is no distinction between when headphones are worn and when they are not worn.

  The present invention has been made in order to solve the above-described problems of the prior art. The purpose of the present invention is to use a sound transmitter suitable for a sound transmitter when using an ear-mounted sound transmitter. It is an object of the present invention to provide an electronic musical instrument that can listen to a sound having an effect suitable for a sound transmitter without taking time and effort with respect to timbres other than a specific timbre.

  In order to achieve the above object, an electronic musical instrument according to claim 1 of the present invention comprises a performance operator (1), a connection part (17) for connecting an ear-mounted sound transmitter (18A, 18B), and the connection. Detecting means (12) for detecting the connection of the sound transmitter to the part, selecting means (2) for selecting a timbre, speaker (15), and connection of the sound transmitter to the connecting part by the detecting means.

1 is a block diagram illustrating an overall configuration of an electronic musical instrument according to an embodiment of the present invention. It is a conceptual diagram of timbre data (FIG. (A)) and effect data (FIG. (B)). It is a figure which shows the flowchart of a main process. It is a flowchart of a panel setting process.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram showing an overall configuration of an electronic musical instrument according to an embodiment of the present invention. This electronic musical instrument is configured as an electronic keyboard musical instrument as an example.

  The electronic musical instrument includes a detection circuit 3, a detection circuit 4, a connection detection unit 12, a ROM 6, a RAM 7, a timer 8, a display device 9, a storage device 10, various interfaces (various I / F) 11, a sound source circuit 13, and an effect circuit 14. Are connected to the CPU 5 via the bus 16. The performance operator 1 includes, for example, a keyboard and a pedal. A sound system 15 is connected to the sound source circuit 13 via an effect circuit 14. A timer 8 is connected to the CPU 5.

  The detection circuit 3 detects the operation state of the performance operator 1, and the detection circuit 4 detects the operation state of the setting operator 2. The CPU 5 controls the entire apparatus. The ROM 6 stores a control program executed by the CPU 5, various table data, and the like. The RAM 7 temporarily stores various input information such as performance data and text data, various flags, buffer data, calculation results, and the like. The timer 8 measures various times such as an interrupt time in the timer interrupt process. The storage device 10 stores various application programs including the control program, various music data, various data, and the like. The display device 9 displays various information.

  The connection part 17 is a terminal (stereo pin jack or USB terminal) into which the ear-mounted sound transmitter 18 is inserted. As examples of the sound transmitter 18, stereo headphones 18A and earphones 18B are exemplified. These can alternatively be connected to the connecting portion 17 and both can be disconnected from the connecting portion 17. When the sound transmitter 18 is connected to the connection unit 17, the connection detection unit 12 sends a detection signal corresponding to the connection to the CPU 5. Upon receiving the detection signal, the CPU 5 detects whether or not the sound transmitter 18 is connected to the connection unit 17 and the type of the connected sound transmitter 18 (whether it is the headphone 18A or the earphone 18B).

  When the connected sound transmitter 18 is connected to the connection unit 17 using the USB terminal, the sound transmitter 18 sends the identification number stored therein to the instrument body at the time of connection, so that the CPU 5 is connected. It is possible to determine whether the sound transmitter 18 is the headphone 18A, the earphone 18B, or which manufacturer's device.

  The various I / Fs 11 include a MIDI (Musical Instrument Digital Interface) interface, an interface for inputting musical sound signals, a communication I / F for communicating with an external device, and the like. The tone generator circuit 13 converts the performance data input from the performance operator 1 or preset performance data into a musical sound signal. The tone generator circuit 13 may be entirely configured by hardware or software, or may be partially configured by software and the remaining portion may be configured by hardware. The effect circuit 14 gives various effects to the musical sound signal input from the sound source circuit 13, and the sound system 15 including a DAC (Digital-to-Analog Converter), an amplifier, a speaker, and the like is input from the effect circuit 14. Converts musical sound signals etc. to sound.

  FIG. 2A is a conceptual diagram of timbre data. As tone color data, waveform data of tone colors A and B and other tone colors are stored in advance in the waveform data area of the ROM 6. The timbre A and the timbre B are “specific timbres”. For specific timbres, waveform data of each timbre is stored in association with the type of the ear-mounted sound transmitter 18 as another timbre predetermined as corresponding to the specific timbre. Has been. That is, corresponding to the timbre A, the timbre ΔA1 is stored as waveform data for the headphone 18A, and the timbre ΔA2 is stored as waveform data for the earphone 18B. Corresponding to timbre B, timbre ΔB1 is stored as waveform data for headphones 18A, and timbre ΔB2 is stored as waveform data for earphones 18B.

  The timbres ΔA1, ΔA2, ΔB1, and ΔB2 are waveform data of a timbre (binaural sampling timbre) created by binaural recording (by binaural sampling) of a musical instrument corresponding to a specific timbre. As will be described later, timbres A and B are timbres to be switched to binaural sampling timbre when the sound transmitter 18 is connected. For example, timbre A is CFX (registered trademark). In particular, the timbre ΔA1 or ΔB1 is adopted when the headphones 18A are connected, and the timbre ΔA2 or ΔB2 is adopted when the earphones 18B are connected. The timbres other than the timbres A and B are not the objects to be switched to the binaural sampling timbre, and the timbre is sounded with the selected timbre regardless of the connection of the sound transmitter 18.

  FIG. 2B is a conceptual diagram of effect data. The effect data is an effect parameter used for adding an effect, and is stored in the effect setting area of the ROM 6 in advance. Note that the timbre data and the effect data may be stored in separate memories. Among the plurality of effect data, in particular, effect data 1 is a performance sound using a stereophonic optimizer (predetermined effect) when the selected tone color is a tone color other than the above-mentioned specific tone color and when the sound transmitter 18 is connected. Is a parameter for processing. The effect data can be read out and set in the effect circuit 14 according to the setting by the setting operator 2, and as will be described later, when the selected timbre is a timbre other than a specific timbre, the sound transmitter 18 is used. When the is connected, the effect data 1 can be read and set in the effect circuit 14.

FIG. 3 is a flowchart of the main process. In the process of this flowchart, the program stored in the ROM 6 or the storage device 10 is read out to the RAM 7 and the CPU 5
It is realized by being executed, and is started when the power is turned on. First, the CPU 5 performs initial setting by setting initial values in various registers (step S101). Next, the CPU 5 executes a panel process of FIG. 3 described later (step S102).

  Next, the CPU 5 generates a performance signal, that is, a performance signal and executes a sound production / mute process (step S103). For example, when the reproduction process is executed, the performance data is read and the generated performance signal is transmitted to the tone generator circuit 13. When a real-time performance is being executed, a key code (pitch information), velocity (volume information), and key on / off signals corresponding to the operated performance operator 1 are detected by the detection circuit 3, and A performance signal corresponding to the detection result is transmitted to the tone generator circuit 13. The sound source circuit 13 generates a sound signal based on the received performance signal and the current tone color setting. At that time, the tone generator circuit 13 reads out the timbre data corresponding to the current timbre setting from the ROM 6. When the effect processing is set, the effect circuit 14 reads the currently set effect data from the ROM 6 and gives an effect to the sound signal generated by the sound source circuit 13 based on the effect data. The sound system 15 amplifies the sound signal input from the effect circuit 14 and produces a sound.

  Next, the CPU 5 executes other processing (step S104), and returns the processing to step S102. Note that when the power is turned off in the panel setting (S102), the processing in FIG. 3 ends.

  FIG. 4 is a flowchart of the panel setting process executed in step S102 of FIG. First, the CPU 5 determines whether the plug (for example, USB connector) of the sound transmitter 18 is inserted, that is, the sound transmitter 18 is connected to the connection unit 17 based on the detection signal from the connection detection unit 12. It is determined whether or not there is (step S201). As a result of the determination, if the plug is not inserted, speaker sound generation, that is, sound generation by the sound system 15 is performed, and the process proceeds to step S206. On the other hand, when the plug is inserted, the CPU 5 determines the connected device based on the detection signal from the connection detection unit 12, that is, the type of the sound transmitter 18 connected to the connection unit 17 (headphone 18A, earphone). 18B) (step S202).

  Then, the CPU 5 determines whether or not the headphones 18A are connected to the connection unit 17 based on the connected device determination result (step S203). If the headphones 18A are connected, the selected timbre is the specific timbre ( It is determined whether or not the tone color is A or B (step S204). If the selected timbre is a specific timbre, the CPU 5 switches the timbre setting to the timbre corresponding to the selected timbre and corresponding to the headphone 18A in order to switch the timbre setting to the corresponding binaural sampling timbre (step S205). . For example, if the selected timbre is timbre A, the timbre setting is switched to timbre ΔA1, and if the selected timbre is timbre B, the timbre setting is switched to timbre ΔB1. Specifically, the CPU 5 switches the timbre setting by switching the program change number. The tone generator circuit 13 reads timbre data corresponding to the timbre setting after switching from the ROM 6. Thereby, in the performance process of step S103, with respect to the specific selected tone color, it is possible to hear the sound with a binaural tone color for headphones more suitable for the headphones 18A.

  On the other hand, if it is determined in step S204 that the selected tone color is a tone color other than the specific tone color, the CPU 5 does not change the tone color setting, and performs a process step so as to cope with the connection of the headphones 18A using the stereophonic optimizer. Proceed to S210. In step S210, the CPU 5 sets the effect data 1 in the effect circuit 14 as effect data used for adding an effect. As a result, in the performance process of step S103, with respect to timbres other than the specific timbre, it is possible to hear a sound to which an effect suitable for the sound transmitter is applied without taking the trouble of preparing corresponding timbre data. . After steps S205 and S210, the process proceeds to step S206. In step S206, the CPU 5 executes other processing. In step S206, it is possible to accept a timbre selection and effect selection by the user using the setting operator 2. Thereafter, the process of FIG. 4 ends.

  If the result of the determination in step S203 is that the headphones 18A are not connected to the connection unit 17, the CPU 5 determines whether or not the earphones 18B are connected to the connection unit 17 (step S207). If the earphone 18B is not connected to the connection unit 17, the CPU 5 advances the process to step S206. On the other hand, when the earphone 18B is connected to the connection unit 17, the CPU 5 determines whether or not the selected tone color is a specific tone color (one of the tone colors A and B) (step S208). If the selected tone color is a specific tone color, the CPU 5 switches the tone color setting to the tone color corresponding to the selected tone color and corresponding to the earphone 18B (step S209). For example, if the selected timbre is timbre A, the timbre setting is switched to timbre ΔA2, and if the selected timbre is timbre B, the timbre setting is switched to timbre ΔB2. Thereby, about a specific selection tone color, a sound can be heard with the binaural tone color for earphones more suitable for the earphone 18B. Thereafter, the process proceeds to step S206.

  On the other hand, if it is determined in step S208 that the selected timbre is a timbre other than the specific timbre, the CPU 5 applies the effect processing using the stereophonic optimizer without switching the timbre setting to the binaural sampling timbre. In order to cope with the wearing of 18A or earphone 18B, the process proceeds to step S210.

  Therefore, in the performance processing of step S103 in FIG. 3, the current tone color setting is timbre ΔA1 or ΔB1 if step S205 is passed, and is timbre ΔA2 or ΔB2 if step S209 is passed. If step S204 or step S209 has not been performed, the current tone color setting remains the selected tone color A or tone color B. On the other hand, in the effect setting, the read effect data is the effect data 1 if it has passed through step S210, and remains the selected effect data if it has not passed step S210.

  According to the present embodiment, when the sound transmitter 18 is not connected to the connection unit 17, the CPU 5 causes the sound system 15 to generate a sound with the selected tone color. On the other hand, when the sound transmitter 18 is connected to the connection unit 17, the CPU 5 performs processing according to the selected tone color on the performance tone (sound switched to the tone for the corresponding tone transmission device, Alternatively, the sound transmitter 18 generates a sound obtained by processing a performance sound using a predetermined effect according to the selected tone color. As a result, when the ear-mounted sound transmitter 18 is used, it is possible to hear a sound that has been processed according to the selected tone color.

  For example, when the selected timbre is a specific timbre (A, B) as a process corresponding to the selected timbre, the CPU 5 selects a binaural sampling timbre (ΔA predetermined) corresponding to the specific timbre. , ΔB), and the performance sound is generated from the sound transmitter 18. As a result, for a specific selected tone color, it is possible to hear a tone color more suitable for a sound transmitter. Further, as a process according to the selected tone color, the CPU 5 uses a predetermined effect (stereophonic optimizer) predetermined for the sound transmitter when the selected tone color is a tone color other than the specific tone color. The sound processed from the performance sound is generated from the sound transmitter 18. As a result, with respect to timbres other than a specific timbre, it is possible to hear a sound to which an effect suitable for the sound transmitter is imparted without taking the trouble of acquiring and storing timbre data.

  Further, since the timbre of the switching destination is made different according to the type of the sound transmitter 18 connected to the connection unit 17, a more appropriate sound according to the type of the sound transmitter can be heard.

  In the present embodiment, a keyboard instrument is exemplified as an electronic musical instrument, but the present invention is not limited to this, and the present invention can be applied to various electronic musical instruments such as guitars, percussion instruments, and wind instruments. That is, any electronic musical instrument that can select sound generation by a speaker and sound generation by an ear-mounted sound transmitter may be used.

  The ear-mounted sound transmitter 18 may be an open type headphone, a bone conduction type headphone, an earphone, or the like, and a tone color suitable for each may be prepared and switched according to connection.

  In addition, since the manufacturer of the ear mounted sound transmitter 18 can be determined with the ear mounted sound transmitter 18 using the USB terminal, a different tone color can be prepared for each manufacturer.

  Although the present invention has been described in detail based on preferred embodiments thereof, the present invention is not limited to these specific embodiments, and various forms within the scope of the present invention are also included in the present invention. included.
