Description

Description: TECHNICAL FIELD The present invention relates to an electronic wind instrument.

[Background] Conventional electronic wind instruments are configured to exclusively perform in real time. Therefore, it was not possible to reproduce the performance state later, as in the present invention.

On the other hand, there is a wind technique as a special playing technique for electronic wind instruments, but it is very difficult for beginners to learn the wind technique, so that even when playing in real time, it is easy to get the musical tone that you expect I couldn't do that.

[Object of the Invention] Accordingly, an object of the present invention is to provide an electronic wind instrument that facilitates learning of a blowing technique. It is a further object of the present invention to provide an electronic wind instrument capable of reproducing a performance state at a desired time during an actual performance operation. It is another object of the present invention to provide an electronic wind instrument capable of performing a wind instrument performance only by performing a pitch designation operation without performing a breath operation.

[Structure and operation of the invention] In order to achieve the above object, the present invention samples the intensity of the breath that is detected by a breath sensor and stores the sampled breath intensity as breath data. The breath data is read out from the memory, and the musical tone having the pitch specified by the pitch specifying means is controlled in accordance with the read result.

Further, in another aspect of the present invention, in addition to the above features, the strength of biting the mouthpiece detected by the lip sensor is sampled and stored as lip data. The musical tone having the pitch specified by the pitch specifying means is controlled in accordance with the read result.

Therefore, after the sampling, it is possible to perform the performance with the breath effect or the lip effect only by using the finger, and the burden of the blowing on the player is greatly reduced.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

<First Embodiment> FIG. 1 shows the overall configuration of the first embodiment. In FIG. 1, reference numeral 1 denotes a breath sensor for detecting the intensity of the breath to be blown and converting the detected signal into an electric signal. The output of the sensor is an analog signal amplified by a breath detection circuit 2 as shown in FIG. The signal is input to the device 3 and converted into a digital signal. on the other hand,
Reference numeral 4 denotes a lip sensor which detects the biting strength and converts it into an analog electric signal. The output of the lip sensor 4 is input to an A / D converter 5 and converted into a digital signal. The breath sensor 1 and the lip sensor 4 are attached to a mouthpiece 6, as shown in the external view of the musical instrument in FIG.

A plurality of pitch switches 8 are provided on a body 7 connected to the mouthpiece 6. The mouthpiece 6 and the pitch switch 8 are the main performance operators of the electronic wind instrument, and their states, that is, the state of the breath sensor 1, the state of the lip sensor 4, and the state of the pitch switch 8 are controlled by the CPU 9 in FIG. Monitored. In detail, CPU 9 is lip sensor 4
Is received in the form of a digital signal from the A / D converter 5, and the state of the breath sensor 1 is received in the form of a digital signal from the A / D converter 3. The CPU 9 determines the state of the plurality of pitch switches 8 by giving a scan signal KC to a circuit in which these switches 8 are connected in a matrix and reading the result KI, and is specified from the result of the determination. Generate pitch data.

As will be described later, the operation modes of the CPU 9 include a recording mode of blowing data (breath data and lip data) and a reproducing mode. In the recording mode, the CPU 9 stores the lip data read from the lip sensor 4 via the A / D converter 5 and the breath data read from the breath sensor 1 via the A / D converter 3 into the waveform RAM 11 by the address control unit 10.
Addressing and writing each area of In the reproduction mode, breath data and lip data stored in the waveform RAM 11 are read out and used for controlling musical tones.

12 (12A, 12B) are PCM sound sources composed of two modules, each of which has a waveform ROM 1 for storing musical sound waveform data.
2-2, an address control unit 12-1 of the waveform ROM 12, a level control unit 12-3 for controlling a level (envelope), and multiplying the output waveform data of the waveform ROM 12-2 by the level data from the level control unit 12-3. It comprises a multiplier 12-4 and a latch 12-5 that captures the output (sound source module output) of the multiplier 12-5. The output of the sound source module output from each latch 12-5 is added by the adder 13, and is taken into the latch 14. As shown, the level control unit 12-3 of each of the tone generator modules 12A and 12B stores the waveform RAM1
1, and is configured to perform level control according to the output of the waveform RAM 11. Specifically, the output of the waveform RAM 11 is directly input to the level control unit 12-3 of the first sound source module 12A, and the output of the waveform RAM 11 is input to the level control unit 12-3 of the second sound source module 12B. Inverse characteristic generator 1
In step 5, data with the opposite characteristics is input. Therefore,
The level controllers 12-3 of the two modules 12A and 12B generate level data having characteristics opposite to each other. As a result, the musical tone waveform data from the two waveform ROMs 12-2 representing two different timbres are mixed in a so-called cross-fading relationship, and a musical tone whose mixing ratio changes by breath data and lip data is obtained. This is one effect in the reproduction mode.

Further, the output of the waveform RAM 11 is also input to the multiplier 17 via the latch 16. The other input of the multiplier 17 receives the waveform data of the mixed musical tone from the latch 14. As a result, the multiplier 17 outputs mixed tone waveform data whose level has been shifted according to the breath data and lip data of the waveform RAM 11.

This output becomes an audio signal through the latch 18, the D / A converter 19, and the amplifier 20, and is output to the outside.

As described above, in the first embodiment, in the recording mode, the breath data and the lip data from the breath sensor 1 and the lip sensor 4 are sampled by the CPU 9 through the A / D converters 3 and 5, and the waveform is transmitted through the address control unit 10. RAM11
Is stored. In playback mode after sampling, the waveform
Data stored in the RAM 11 is read out, and is directly input to the level control unit 12-3 of the first sound source module 12A, and is input to the level control unit 12-3 of the second sound source module 12B in the form of an inverse characteristic. The tone components whose amplitude ratio is cross-faded are generated by the tone generator modules 12A and 12B.
The waveform RA is further added to the musical sound waveform obtained by synthesizing
Level control based on the data of M is performed. Therefore,
Automatic performance after sampling can be performed according to recorded breath data and lip data as a blowing input.

<Second Embodiment> In the first embodiment, the data of the breath sensor 1 and the lip sensor 4 are sampled in the waveform RAM 11, and the data is automatically played at the time of reproduction.
In the embodiment, at the time of reproduction, the performance is reproduced by combining the pitch input from the pitch switch 8 with the information of the stored breath data and lip data. That is, after the sampling, the performance with the breath effect and the lip effect can be performed only by using the finger without having to perform the blowing operation.
FIG. 3 shows a main configuration of the second embodiment.

Among the components of the CPU 9M, the up counter 91, the change detection unit 92, and the coding and data writing unit 93 constitute storage means for sampling and storing breath data and lip data in the sequencer memory 11M. Also, a down counter 94, a data reading / decoding unit 95, a pitch data generation unit
96 and the tone control generation unit 97, the sequencer memory 11
Breath data, lip data and pitch switch 8 from M
A tone control means for controlling the sound source 12 and performing a wind instrument by combining the pitch switch input from the musical instrument. By the mode control unit 98, only the storage means operates in the recording mode, and the tone control means operates in the reproduction mode.

More specifically, the clock generator 90 generates a clock having a frequency according to tempo data from a tempo volume (not shown). This clock is used for sequencer memory 11
It corresponds to the recording / playback resolution for M.

In the recording mode, the clock of the clock generator 90 is input to the up-counter 91 and causes the counter 91 to perform a count-up operation. The change detecting unit 92 receives breath data and lip data (data corresponding to the data from the A / D converters 3 and 5 in FIG. 1) and checks a change in the data. When detecting a change in the data, the change detecting section 92 inputs the data to the coding / data writing section 93. On the other hand, the coding and data writing unit 93 is the up counter at that time.
The contents of 91 (representing the elapsed time between performance events) are read, a unique identification code is added to each of the new data from the change detection unit 92 and the time data from the up counter 91, and they are written to the sequencer memory 11M. . Next, the up counter 91 is cleared by a signal from the change detection unit 92, and the time counts up to the next performance event.

Thus, in the recording mode, the data from the breath sensor 1 and the lip sensor 4 are stored in the sequencer memory 11M.
Will be recorded. FIG. 4 shows a recording example of the sequencer memory 11M. Following the identification code, the type of data (breath data, lip data, or time data) indicated by the identification code is stored in the sequencer memory 11M. In the figure, the identification code for breath data is AOH, the identification code for lip data is BOH, and the identification code for time data is E.
Indicated by OH.

On the other hand, in the reproduction mode, the clock of the clock generator 90 is input to the down counter 94. When the count reaches zero, the down counter 94 generates a borrow output and inputs it to the data reading / decoding unit 95. When a borrow output indicating the arrival of the next reproduction event is given from the down counter 94, the data reading / decoding unit 95 responds to the borrow output.
Read the next data (including the identification code) from 11M,
The data to be reproduced by decoding the identification code is sent to the musical tone control generator 97. When the identification code indicates time data, the sequencer memory 11M resets the time data to the down counter. As a result, the down counter 94
Moves to the timing until the next playback event. Tone control generator
97 is supplied with breath data or lip data to be processed from the data reading / decoding unit 95 and pitch designation data generated by the pitch data generation unit 96 and determined by the current state of the pitch switch 8. Music control generation unit 97
Executes sound generation processing, mute processing, or volume control processing based on breath data. At the time of the pronunciation process, the pitch data, the key-on code, and the attack envelope parameter are obtained from the current pitch designation data provided from the pitch data generation unit 96 and the breath data provided from the data reading and decoding unit 95. The sound is generated and sent to the sound source 12 to start the tone generation. At the time of the silencing process, a release envelope parameter is generated and sent to the sound source 12 to end the tone generation. When a tone is being generated, a level parameter is generated from the breath data and transferred to the sound source 12, thereby controlling the volume of the tone being generated. Also, when lip data is given from the data reading / decoding unit 95 during sound generation, a pitch modulation parameter is generated from the data and transferred to the tone generator 12, thereby controlling the pitch of the musical sound being sounded.

For reference, FIG. 5 shows a flow of the operation of the embodiment in the reproduction mode. This flow is executed each time a clock is generated from the clock generator 90 in FIG.

Accordingly, in the reproduction mode, in the time chart of FIG. 6, the breath data and the lip data are given from the sequencer memory 11M, the pitch designation state is given from the pitch switch 8, and according to the instantaneous value of each data. , A wind instrument performance is played. That is, the breath data is used for tone generation timings (steps 5-1 to 5-9, 5-11, and 5-15) and tone amplitude control (step 5-10). (Step 5-
12, 5-13), the lip data is used to change the reference frequency of the musical tone to achieve pitch bend (step 5-).
13). Therefore, the performer only needs to perform the fingering operation using the pitch switch 8 as the performance operation, and the other operations are unnecessary since they are sampled in the sequencer memory 11M in advance. Therefore, the burden of the blowing operation is reduced. In addition, by securing the most successful data in the sequencer memory 11M after performing the blowing operation several times, it becomes possible to perform a very good wind instrument performance during reproduction.

This concludes the description of the embodiments, but various modifications and changes are possible. For example, any other desired parameters can be used as the parameters of the musical tone controlled by the breath data and the lip data.

According to the first aspect, breath data from the breath sensor is sampled and stored, read out after sampling, and the musical tone is controlled in accordance with the readout result. It becomes possible.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, the biting intensity from the lip sensor is sampled and stored as lip data, and read out at an arbitrary time thereafter, and the musical tone is controlled according to the read result. This makes it easy to learn the lip playing technique unique to wind instruments, and eliminates the need to perform a lip operation when performing a wind instrument at the time of sampling reproduction, thereby reducing the operation burden on the player.
