[Problems to be solved by the invention]
By the way, none of the above-described conventional wind instrument type electronic musical instruments has an auto harmony function for automatically adding a harmony musical sound. Therefore, the wind instrument type electronic musical instrument may be configured to have an auto harmony function. However, in such a case, various setting operations are naturally required to perform various settings related to the harmony musical sound added by the auto harmony function for the wind instrument type electronic musical instrument. Therefore, like a conventionally known keyboard-type electronic musical instrument, for example, a display device such as a display is installed on a wind instrument-type electronic musical instrument, and various screens such as a harmony type display screen are displayed there. It is conceivable that the performer can make various settings related to the harmony musical sound while viewing the various displayed screens. However, various settings in accordance with the conventional screen display are time-consuming to operate, and it takes a very long time to switch the setting contents. In addition, wind instrument-type electronic musical instruments are different from keyboard-type electronic musical instruments, and it is necessary to newly install a dedicated controller or a large display on the electronic musical instrument body for various settings related to harmony musical sounds. However, there is a problem that it is difficult to install a new electronic musical instrument from the viewpoints of downsizing, weight reduction, and cost reduction. .

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
[0009]
FIG. 1 is a hardware block diagram showing an embodiment of the overall configuration of a wind instrument type electronic musical instrument according to the present invention. The electronic musical instrument shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic musical instrument. A read-only memory (ROM) 2, a random access memory (RAM) 3, a storage device 4, a performance instruction receiving interface 5, and a panel operator are connected to the CPU 1 via a communication bus 1D (for example, a data and address bus). 6, a display 7, a sound source 8, a DSP (abbreviation of Digital Signal Processor) 9, and an external interface 11 are connected to each other. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse and gives the generated clock pulse as a processing timing command to the CPU 1 or as an interrupt command to the CPU 1. The CPU 1 executes various processes such as a “main process” (see FIG. 2) described later according to these instructions.
[0010]
The ROM 2 stores various programs related to performance conditions such as various programs executed or referred to by the CPU 1, performance sounds generated according to performance operations by the performer, or harmonies that are automatically added to the performance sounds. Data etc. are stored. The RAM 3 is used as a working memory for temporarily storing various data generated when the CPU 1 executes a predetermined program, or as a memory for storing a program currently being executed and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like.

When no control program is stored in the ROM 2, the control program is stored in the storage device 4 (for example, a hard disk), and the control program is stored in the ROM 2 by reading it into the RAM 3. The CPU 1 can be operated as described above. In this way, control programs can be easily added and upgraded. The storage device 4 is not limited to a hard disk (HD), but may be a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (abbreviation of Digital Versatile Disk), or the like. The storage device may use various forms of external recording media that are detachable. Alternatively, a semiconductor memory or the like may be used.
[0012]
The performance instruction reception interface 5 is an interface for detecting an operator state in which a combination of operation states of the performance operator 5A is input in accordance with each operation state of the plurality of performance operators 5A, and at the same time, following a voice input from the microphone 5B. This is an interface for inputting pitches. In the wind instrument type electronic musical instrument shown in this embodiment, the musical performance sound is played at a pitch determined according to the combination of the pitch of vibration sound such as voice given by the performer and the operation state of the performance operator operated by the performer. appear. Therefore, the performance instruction reception interface 5 acquires these pieces of information from the performance operator 5A and the microphone 5B. The performance operator 5A is provided with a plurality of switches whose operation states are referred to when selecting the pitch of the musical performance, and has a key switch corresponding to each switch. Needless to say, it can be used for pitch specification at the time of musical performance, and it can also be used as an input means for inputting a timbre, rhythm, etc. used when performing a musical performance.
[0013]
Here, an operation method for generating musical performance sounds in the electronic musical instrument, that is, a performance method will be briefly described. However, here, an electronic musical instrument simulating a trumpet, that is, a trumpet type electronic musical instrument having three operation elements of the first to third performance pistons as the performance operation element 5A will be described as an example. First, the performer emits a sound having a pitch frequency of a musical tone to be generated toward the microphone 5B. The voice uttered toward the microphone 5B may be, for example, only a nose song, or may be simple sounds such as “Ah” and “Woo”. In short, any sound may be emitted as long as it has a specific frequency. Simultaneously with the sound input to the microphone 5B, the performer presses the first to third performance pistons in the same manner as a natural instrument trumpet or the like. A plurality of pitch candidates are simultaneously designated as the pitch of the generated musical tone by the combination of the non-operating state and the operating state of the first to third performance pistons. Of the plurality of pitch candidates, the pitch of the frequency closest to the frequency of the input voice is determined as the pitch of the generated musical sound. Since such a method for determining the pitch is known, the description thereof is omitted here. Then, a musical performance tone having a predetermined tone color (for example, a trumpet tone) having the determined pitch is generated in synchronization with the voice. In this case, if the automatic harmony function is set to be executed, a harmony tone that is combined with the generated musical tone to form a harmony is added to the musical tone. . The harmony musical sound is generated with a different tone color (for example, a trombone sound, etc.) different from the performance musical sound selected in advance.
[0014]
Returning to the description of FIG. 1, the panel operator 6 is used to perform various setting operations such as setting the music performed by the performer, and setting various performance conditions such as the tone used for the performance tone and the harmony tone. Is a setting operator including In this embodiment, for example, operation buttons such as a voice button, a Δ / ▽ button, and a dial are arranged as setting operation elements used for setting a tone color used for performance musical sounds and harmony musical sounds. Of course, in addition to this, various operators used for selecting, setting, and controlling the pitch, tone color, effect, and the like may be included. When the operation state of each operation member of the panel operation member 6 is detected, switch information corresponding to the operation state is output to the CPU 1 via the communication bus 1D.

Further, an effect circuit (not shown) may be disposed between the sound source 8 and the sound system 10 to give various effects to the musical sound signal generated from the sound source 8. Any conventional configuration may be used for the configuration of the sound source 8, the DSP 9, and the sound system 10 (and the effect circuit). For example, the sound source 8 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be constituted by dedicated hardware or by software processing by the CPU 1. Also good.
[0017]
The external interface 11 is, for example, a MIDI interface or a communication interface for transmitting and receiving various data such as timbre between the electronic musical instrument and an external device (not shown). The MIDI interface inputs MIDI standard control information (MIDI data) from an external device (in this case, MIDI device, etc.) to the electronic musical instrument, or sends MIDI standard control information from the electronic musical instrument to another MIDI device. It is an interface for outputting to the etc. Other MIDI devices may be any devices that generate MIDI format data in response to user operations, and include any type of controls such as keyboard type, guitar type, wind instrument type, percussion instrument type, and gesture type ( Alternatively, it may be a device). The communication interface is connected to a wired or wireless communication network such as a LAN, the Internet, or a telephone line, and is connected to an external device (in this case, a personal computer or a server computer) via the communication network. This is a communication interface for taking in automatic performance data generated by the external device to the electronic musical instrument side. The communication interface is also used for downloading various programs, various data, and the like from a server computer connected via a communication network to the mixer body. Note that the communication interface may be both wired or wireless and may include both.
[0018]
When the external interface 11 is composed of a MIDI interface, the MIDI interface is not limited to a dedicated MIDI interface, but is RS232-C, USB (Universal Serial Bus), IEEE 1394 (I Triple E 1394), etc. The MIDI interface may be configured using a general-purpose interface. In this case, data other than MIDI event data may be transmitted and received simultaneously. When a general-purpose interface as described above is used as the MIDI interface, other MIDI devices may be able to transmit and receive data other than MIDI event data. Of course, the data format is not limited to the data in the MIDI format, but may be in other data formats. In that case, the MIDI interface and other MIDI devices are configured accordingly.
[0019]
The wind instrument type electronic musical instrument shown in FIG. 1 has an auto harmony function, and is electronically determined according to the combination of the pitch of the vibration sound given by the performer and the operation state of a predetermined performance operator by the performer. A musical tone (original tone) is generated with the tone color of, and a harmony musical tone with a predetermined tone color is generated in addition to the musical tone (original tone). The “main process” executed by the electronic musical instrument will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of “main processing”. In the “main process”, various setting processes for setting performance conditions such as the tone used for the harmony musical sound that is set to use the auto harmony function, and the generated musical tone and the harmony musical sound are performed simultaneously or independently Perform performance processing to generate. The detailed operation of the process will be described below according to the flowchart shown in FIG. The “main process” is a process that is started at the same time as the power source of the electronic musical instrument body is turned on, and is repeatedly processed until the power source of the electronic musical instrument body is turned off.
[0020]
In step S1, initialization is executed. The initialization includes, for example, processing such as erasing various data stored in the RAM 3 or clearing device settings already set in the electronic musical instrument. In step S2, “panel setting processing” is executed. Although details will be described later (see FIG. 3 to be described later), in the panel setting process, the operation state of the setting operation element (panel operation element 6) arranged on the panel is simultaneously processed simultaneously with the process. (Not shown), and device settings are executed for the electronic musical instrument in accordance with the obtained operating status of each setting operator. In step S3, "performance processing" is executed. Although details will be described later (see FIG. 5 described later), in the performance process, the operation status of the performance operator 5A is acquired from an operator scan process (not shown) that is concurrently processed at the same time as the process. In accordance with the operation status of the performance operator 5A and the pitch information acquired from the microphone 5B, a process for generating a musical tone and generating a sound from the speaker is executed. In addition, if the electronic musical instrument is set to use the auto harmony function, in addition to the above-mentioned musical performance sounds, harmony musical sounds are generated, and the processing musical sound and harmony musical sounds are simultaneously generated from the speaker. To do.
In the case where the wind instrument type electronic musical instrument described above has an automatic accompaniment function, a musical tone or a harmony musical tone is generated based on a performance operation performed by the performer in the “performance processing” of step S3. An accompaniment or the like according to predetermined performance data selected in advance may be automatically played and pronounced.
[0021]
Next, the “panel setting process” (see step S2 in FIG. 2) executed in the “main process” described above will be described. FIG. 3 is a flowchart showing an example of the “panel setting process”. This “panel setting process” is a process of performing device setting for the electronic musical instrument in accordance with the operation of the panel operator 6.
[0022]
In step S11, it is determined whether there is a panel input. That is, it is determined whether any of the setting operators of the panel operators 6 has been operated by the performer. When it is determined that the panel operator 6 is not operated by the performer and there is no “panel input” (NO in step S11), there is no operation of the panel operator 6, that is, a device setting operation for executing the auto harmony function. Therefore, the process is terminated without setting the device for the electronic musical instrument. On the other hand, if it is determined that the panel operator 6 is operated by the performer and “panel input is present” (YES in step S11), the panel input is operated by the setting operator on the panel operator 6. It is determined whether it is due to this (step S12, step S13, step S14). That is, in each processing of step S12 to step S14, it is determined which of the plurality of setting operators arranged on the panel, the panel input is detected by operating the setting operator. To do.
[0023]
If it is detected that “panel input is present” by pressing the setting operator “Δ / ▽ button” among the panel operators 6 (YES in step S12), the process proceeds to step S15. In the case where the setting operator “dial” is operated rather than the operation of the “△ / ▽ button” (YES in step S13), the above-mentioned “Δ / ▽ button” is pressed. As in the case of, the process goes to step S15. If the setting operator “voice button” is not released because the “Δ / ▽ button” or “dial” is operated (YES in step S14), the process proceeds to step S22. If any of the above “△ / ▽ buttons”, “Dial” or “Voice button” is not detected as “panel input” detected, that is, other setting operators When the operation is performed or when the “voice button” is released (NO in step S14), processing according to the instruction of the operated setting operator is executed. Examples of such a process include a process of canceling a device setting state (“mode A” or “mode B” to be described later) for executing the auto harmony function that has been set for the electronic musical instrument. As described above, different device setting processes are executed depending on the type of the panel operator 6 operated by the performer.
[0024]
In step S15, which is executed when the “△ / ▽ button” or “dial” is operated (YES in step S12 or YES in step S13), the “voice button” is simultaneously pressed when these setting operators are operated. It is determined whether or not it has been continued. That is, it is determined whether either the “Δ / ▽ button” or the “dial” and the “voice button” are operated simultaneously. If it is determined that the “voice button” has not been kept pressed (NO in step S15), the device setting state (also referred to as mode) for the electronic musical instrument is currently set to “tone setting mode”. It is determined whether or not there is (step S16). If it is not currently set in the “tone setting mode” (NO in step S16), various settings such as the volume according to the operation amount of the setting operator in other modes other than the “tone setting mode” are changed. Change processing is performed (step S17). If it is currently set in the “tone color setting mode” (YES in step S16), the tone color used for the musical performance tone is selected and changed in the “tone color setting mode” according to the operation amount of the setting operator (step S18). . In other words, the “tone color setting mode” is a mode for setting the tone color of the musical tone that is generated in response to the performance operation by the performer.
[0025]
On the other hand, if it is determined in step S15 that the “voice button” is kept pressed during the operation of the “Δ / ▽ button” or “dial” (YES in step S15), the electronic musical instrument It is determined whether or not the device setting state for the current mode has already been set to either “mode A” or “mode B” (step S19). In this embodiment, “mode A” is a mode for executing a performance in which a harmony musical sound one octave higher than a musical performance tone (original sound) is added, and “mode B” is a performance musical sound (original sound). On the other hand, this mode is for executing a performance to which a harmony musical sound one octave below is added. If the electronic musical instrument has not been set to the “mode A” or “mode B” mode (NO in step S19), the device setting state for the electronic musical instrument is set to “mode A” or “mode B”. Is set to one of the modes (step S20). For example, when the performer presses the “△ button” while pressing the “voice button”, the mode is set to “mode A”, and when the “▽ button” is pressed while holding the “voice button” Set the mode to “Mode B”. When the performer operates the “dial” while pressing the “voice button”, the mode is set to either “mode A” or “mode B” in accordance with the rotation direction of the dial. When the device setting state for the electronic musical instrument has already been set to either “mode A” or “mode B” (YES in step S19), the “△ / ▽ button” or “dial” operation is performed. Accordingly, the timbre used for the harmony musical sound is selected and changed (step S21).
[0026]
In step S14, when either the “△ / ▽ button” or the “dial” is not operated but the “voice button” is released (YES in step S14), It is determined whether or not simultaneous input has been performed by operating the “Δ / ▽ button” or “dial” while the “voice button” is kept pressed (step S22). If there is no simultaneous input in which either the “△ / ▽ button” or the “dial” is operated while the “voice button” is being pressed (NO in step S22), the device setting state for the electronic musical instrument is changed to “ "Tone color setting mode" is set (step S23).
[0027]
As described above, by simultaneously operating either the “voice button” and the “△ / ▽ button” or “dial”, the musical tone (original sound) is one octave higher (when mode A is set). ) Or a device setting for the electronic musical instrument to execute a performance with a harmony musical tone one octave lower (when set to mode B). In addition, when the mode is set to either mode A or mode B, by simultaneously operating either the “voice button” and the “△ / ▽ button” or “dial”, the tone used for the harmony musical sound can be selected. You can make changes.
[0028]
Here, the tone color setting operation according to the operation of the panel operator will be briefly described. FIG. 4 is an operation flow showing an embodiment of timbre determination based on the operation of the setting operator. Tones used for musical performances can be selected from multiple types of timbres (shown here) by operating the “△ / ▽ buttons” or “dial” when the “tone setting mode” is set as the device setting. , Trumpet, trombone, strings, flute) can be selected and changed sequentially. For example, when the “▽ button” or “dial” is operated from top to bottom, depending on the amount of operation, the trumpet, trombone, strings, and flute order (see the solid arrows on the left side of the figure) Can be changed. On the other hand, when the “△ button” or “dial” is operated from the bottom to the top, the trumpet, the flute, the strings, and the trombone are arranged in this order according to the amount of operation (see the dotted arrows on the left side in the figure). You can change the tone. On the other hand, the timbre used for the harmony music is to operate the “voice button” and “△ / ▽ button” or “dial” simultaneously when “mode A” or “mode B” is set as the device setting. Thus, a plurality of types of timbres (here, trombone, tuba, piano, glocken) can be selected and changed sequentially. Even in this case, depending on the operation amount of the “△ / ▽ button” or “dial”, the order of trombone, tuba, piano, glocken (see the arrow indicated by the solid line on the right side in the figure) or the reverse order (see FIG. You can change the timbre (see the dotted arrow on the right side).
[0029]
As for the timbre used for the harmony musical tone, the recommended timbre that matches the timbre used for the performance musical tone is matched in advance, and the corresponding timbre is automatically selected according to the selection of the timbre used for the musical performance tone. Is done. When the timbre used for the musical tone is a brass instrument timbre, the use of the same brass instrument timbre as that used for the harmony musical sound has the effect of increasing the thickness of the sound. Therefore, for example, if the tone used for the performance tone is “trumpet”, “Trombone” is used as the tone used for the harmony tone, and if the tone used for the performance tone is “Trombone”, it is changed to the harmony tone. “Tuba” may be associated with the timbre to be used. In addition, when the tone used for the musical tone is a continuous tone, using a percussion instrument / string percussion tone as the tone used for the harmony musical tone has the effect of increasing the glittering sound. Therefore, for example, when the tone used for the musical tone is “strings”, “piano” is used as the tone used for the harmony musical tone, and when the tone used for the musical tone is “flute”, it is used for the harmony musical tone. It is preferable to associate “Glocken” as a timbre. Of course, it is needless to say that the performer can appropriately set the correspondence between the timbre used for the musical tone and the timbre used for the harmony musical tone.
[0030]
Next, the “performance process” (see step S3 in FIG. 2) executed in the “main process” described above will be described. FIG. 5 is a flowchart showing an example of the “performance processing”. This “performance process” is a process in which the electronic musical instrument actually produces a musical tone based on the device settings.
[0031]
In step S30, it is determined whether there is a voice pitch extraction. That is, when an input of a voice uttered by the performer is received from the microphone 5B, the pitch (pitch) of the voice is detected when the input voice has a volume higher than a certain level. First, it is determined whether or not the pitch of the voice has been extracted. If the pitch of the voice has not been extracted (NO in step S30), the process ends without generating a musical tone due to the performance operation of the performer and without generating a harmony musical tone due to the auto harmony function. As described above, in the wind instrument type electronic musical instrument shown in this embodiment, musical tones are performed according to the combination of the pitch of the vibration sound given by the performer and the operation states of a number of performance operators operated by the performer. Therefore, if there is no voice input by the performer, no musical sound is generated. Further, if no musical tone is generated by the performance operation of the performer, it is natural that no harmony musical tone added to the musical tone is generated. Therefore, when there is no voice input by the performer, no harmony musical sound is generated.
[0032]
If the pitch of the voice has been extracted (YES in step S30), the pitch of the musical tone is determined based on the operation status of the performance operator and predetermined information (pitch information) regarding the extracted pitch (step). In step S31, a performance signal is generated with a tone color for a performance tone that has been set with the pitch of the determined performance tone (step S32). In this way, preparations are made for generating musical performance sounds by the performance operation of the performer. Then, it is determined whether the device setting state for the electronic musical instrument is currently set to “mode A” (step S33) or whether it is set to “mode B” (step S35). When “mode A” is set (YES in step S33), a pitch that is one octave higher than the pitch of the generated musical tone is determined, and the pitch that is one octave higher is determined. A harmony signal is generated with the tone color for the selected harmony musical tone (step S34). On the other hand, when “mode B” is set (YES in step S35), a pitch that is one octave lower than the pitch of the generated musical sound is determined, and the determined sound one octave lower is determined. A harmony signal is generated with the tone color for the selected harmony musical tone (step S36). In this way, preparations are made for generating a harmony musical sound to be added to the musical performance sound by the performer's performance operation. In step S37, a performance tone and a harmony tone are simultaneously generated based on the generated performance signal and harmony signal.

In the above-described embodiment, as the automatic harmony function, “mode A” for adding a harmony tone that is one octave higher than the pitch of the musical tone, and one octave lower than the pitch of the musical tone. Although only one of the “mode B” modes for adding harmony musical tones can be set, this is not restrictive, and “mode A” and “mode B” are set simultaneously. You may be able to do that. In such a case, it is possible not only to generate a dual that adds a harmony tone only one octave above or one octave below the pitch of the musical tone, but also to the pitch of the musical tone. It is possible to generate a trio that simultaneously adds harmony musical tones that are one octave above and one octave below. Moreover, the pitch of the harmony musical sound added to the pitch of the performance musical tone is not limited to the pitch one octave above or one octave below, and it may be determined with an appropriate pitch. Further, in such a case, the performer may be able to appropriately determine the pitch.

The above-described wind instrument type electronic musical instrument may be provided with a performance guide function so that the player can be instructed which performance operator 5A should be operated.
In the above-described embodiment, a harmony tone is added to a performance tone when the “voice button”, “△ / ▽ button”, and “dial” setting operators are combined and operated. However, the present invention is not limited to this, and other setting operators may be used.
In the above-described embodiment, the pitch input means uses an air vibration detector such as the microphone 5B for inputting the pitch according to the voice uttered by the performer. Instead of this, it may be arranged on the “throat bud” of the human body and contacted to detect vibration and input the pitch. Alternatively, a sensor that vibrates with the strength of the breath blown by the performer may be used to input a pitch according to the vibration.

Note that the electronic musical instrument according to the present invention is not limited to one in which the panel operator 6, the display 7 or the sound source 8 is built in one electronic musical instrument main body, but each is configured separately, and communication such as an external interface or various networks is performed. Needless to say, the present invention can be similarly applied to a device configured to connect each device using means.
The various processes including the main process described above are not limited to the form of computer software, but can be implemented in the form of a microprogram processed by a DSP (Digital Signal Processor), and are not limited to this form of program. Instead, it may be implemented in the form of a dedicated hardware device configured to include a discrete circuit, an integrated circuit, a large-scale integrated circuit, or the like.
