  The keyboard device 30 is configured to include a performance operator 22 composed of a plurality of keys and an LED 29 installed corresponding to each performance operator (key) 22. Each performance operator (key) 22 is connected to the detection circuit 11 and supplies performance information according to the performance operation of the user. The LED group 29 is, for example, a light emitting diode (LED) capable of emitting light by changing the amount of visible light or infrared light according to a voltage or the like.

  For example, the guide voice generation circuit 25 reads voice guide data for use as a performance guide or key name guide stored in advance in the ROM 8 or the external storage device 15, generates a voice signal, and supplies the voice signal to the light amount modulation circuit 27. . The guide sound generation circuit 25 may be configured by the sound source circuit 18.

  The LED signal control device 26 includes a light amount modulation circuit 27 and an LED signal allocation circuit 28. The light intensity modulation circuit 27 amplitude-modulates the voltage supplied to the LED group 29 with the audio signal supplied from the guide audio generation circuit 25 and supplies the modulated voltage to the LED signal allocation circuit 28. The LED signal allocation circuit 28 switches the LED 29 that supplies the modulated voltage in accordance with a program for realizing the present embodiment executed by the CPU 9 or the like.

  The attachment I / F 23 is an interface for connecting the attachment 24 according to the present embodiment. The attachment I / F 23 may be configured with a dedicated interface, or a general-purpose interface such as USB may be used. The attachment 24 detects the light emission of the LED 29 when the performer wears it, and converts it into an audio signal. The configuration of the attachment 24 will be described later with reference to FIGS.

  FIG. 2 is a schematic diagram illustrating a configuration example of the attachment 24 and the keyboard device 30 according to the embodiment of the present invention.

  FIG. 2A shows an example in which an LED 29 is arranged at the lower end of each key 22. In this example, since light is emitted from the key 22 upward in the vertical direction, the optical sensor 241 is installed at the lower part (the part corresponding to the belly of the finger) of the attachment part 240 of the attachment 24. The attachment 24 is used by mounting the mounting unit 240 on at least one of the user's fingers and mounting the earphone 243 on the ear.

  The optical sensor 241 is a sensor that can detect incident visible light or infrared light and output a voltage corresponding to the amount of incident light. The signal voltage output from the optical sensor 241 is amplified by the amplifier 242 and is generated by the earphone 243. The LED 29 emits light with an amount of light modulated by the guide sound signal generated by the guide sound generation circuit 25 of FIG. 1, so that the signal charge detected by the optical sensor 241 is a reproduction of the guide sound signal.

  With such a configuration, the user wearing the attachment 24 can hear the guide voice via the earphone 243 when the user holds the finger over the key 22 corresponding to the LED 29 that is emitting light. Since the optical sensor 241 outputs a signal voltage corresponding to the light quantity of the LED 29, the volume of the earphone 243 increases as the optical sensor 241 approaches the key 22 (LED 29). Therefore, in the example shown in FIG. 2A, the distance between the finger and the key 22 can be recognized by the volume.

  Here, the modulation method has been described as amplitude modulation in which the amount of light is changed by returning the amplitude of light, but the interval is sufficiently shorter than the speed of response for converting the light of the attachment 24 into sound and the human audible range. The light quantity may be changed by pulse modulation that emits light in a pulse shape and changes the pulse width at that time. If there is no need to change the volume depending on the distance from the key, another modulation method such as FM modulation may be used, and the attachment 24 capable of demodulation corresponding to the other modulation method may be used.

  As the light emitted from the LED 29, infrared light may be used when the appearance is not to be replaced with a normal electronic musical instrument. In that case, the optical sensor of the attachment 24 is assumed to be compatible with infrared rays. Further, when visible light is used, it can be used as a performance guide for instructing a key to be operated conventionally. Furthermore, you may make it install two LED29 corresponding to each of visible light and infrared rays corresponding to each key. In that case, two optical sensors 241 of the attachment 24 may be prepared corresponding to each of visible light and infrared light, or an optical sensor having sensitivity from visible light to infrared region may be used.

  Further, the attachment 24 is not limited to the configuration of the optical sensor 241, the amplifier 242, and the earphone 243, and may be realized by a combination of a solar cell and the earphone 243, for example. That is, the attachment 24 may be of any configuration as long as it can detect light modulated by the guide sound emitted by the LED 29 and restore the guide sound.

  FIG. 2B shows an example in which the LED 29 is arranged at the base (keyboard device main body side) of each key 22. In this example, since light is emitted from the base of the key toward the key end in the horizontal direction, the optical sensor 241 is installed at the tip of the attachment portion 240 of the attachment 24 (the portion corresponding to the tip of the finger). The other structure is the same as the example shown in FIG.

  Although this embodiment can be realized if the attachment portion 240 of the attachment 24 is at least for one finger, it is preferable that the attachment portion 240 has a plurality of attachment portions 240 and corresponding optical sensors 241 as shown in FIG. In the case of the attachment 24 corresponding to a plurality of fingers, as shown in FIG. 3, the optical sensor 241 corresponding to the desired finger is selectively selected by switching the signal from the optical sensor 241 of each finger by the sensor switching circuit 244. It can be operated. As will be described later, the optical sensor 241 is switched by enabling only the optical sensor 241 corresponding to the finger specified by the fingering event of the performance guide data, so that the volume of the optical sensor 241 becomes closer to the key to be depressed. It is intended to guide fingering so that it goes up. This switching instruction is performed according to a program for realizing the present embodiment executed by the CPU 9 or the like.

  In order to instruct the attachment 24 shown in FIG. 3 to switch, the attachment 24 must be connected to the attachment I / F 23 of the electronic musical instrument 1 as shown in FIG. However, when no switching instruction is given as in the attachment 24 of FIG. 2, it is not necessary to be connected to the attachment I / F 23 of the electronic musical instrument 1.

  In addition, the shape of the mounting portion 240 of the attachment 24 may be independent for each finger as shown in the figure, or a glove-shaped mounting portion 240 is prepared and the optical sensor 241 is installed on each finger. Good. Further, the attachment 24 may be for one hand or for both hands. In the present embodiment, description will be made assuming that the attachment 24 having the attachment portion 240 for five fingers and the optical sensor 241 are attached to both hands.

  FIG. 4 is a block diagram of LED control in key name processing according to an embodiment of the present invention.

  The key name process according to the present embodiment is a process for allowing the user to recognize the key name in a state where the user cannot see the keyboard 30. For example, the visually impaired person does not operate the key, that is, the sound is generated. The key name can be recognized without doing so.

  In this process, the user wearing the attachment 24 (FIG. 1) brings the finger into contact with or close to the key 22 so that the light sensor 241 detects the light modulated by the sound signal of the LED 29 and gives the user a key name. It is to inform.

  For example, the guide voice generation circuit 25 corresponds to the key name of each key such as “here is a de-sharp” as the sound signal of the C key and “here is a de-sharp” as the sound of the C # key. An audio signal is repeatedly generated by periodically reading out audio data (waveform data) stored in the ROM 8 or the external storage device 15. Note that a voice signal may be generated using a well-known voice synthesis method instead of reading the waveform data. Further, the key name guide voice is not limited to the above-mentioned method of calling with the fixed door, but may be called with the moving door after judging the adjustment of the music, or may be the pitch name (see, sea sharp ...). . Further, a musical tone having a pitch corresponding to each key may be output with the currently set tone color, or a key name may be generated with the pitch of each key.

  The audio signal generated by the guide sound generation circuit 25 is sent to the light intensity modulation circuit 27 corresponding to each key name. Each light intensity modulation circuit 27 modulates the power supply voltage with the supplied audio signal and sends it to the LED signal allocation circuit 28. The LED signal allocation circuit 28 converts the received modulation voltage into a plurality of keys corresponding to the respective key names. 22 LEDs 29 are supplied. For example, the light intensity modulation circuit 27 that has received the C key audio signal modulates the power supply voltage with the audio signal and sends it to the LED signal allocation circuit 28. The LED signal allocation circuit 28 converts the modulation voltage from C1 (lowest sound). Assigned to LED 29 of key 22 corresponding to each C sound of C6 (highest sound).

  In this way, light that is light-modulated by the sound signal of the key name of each key is emitted from the LED 29 corresponding to each key. Therefore, when the finger of the user wearing the attachment 24 approaches the range where the light of the LED 29 can be received, the user can demodulate the light of the LED 29 detected by the optical sensor 241 and listen to the key name guide voice. For example, when the user's finger is close enough to receive the light of the LED 29 corresponding to the C2 key, the optical sensor 241 detects the modulated light from the LED 29 of the C2 key and converts it into a signal voltage. The sound signal is demodulated, and the sound “This is a sound” is generated from the earphone 243 via the amplifier 242. Therefore, the user knows that the key with his / her finger close is “do”.

  Here, the LED signal control circuit 26 assigns the same sound to each key (for example, C1, C2, C3...) Different in octave. However, one light modulation circuit is provided for each key. Audio signals may be supplied one by one. In this case, it is possible to use a voice that indicates the C key by indicating the octave difference, such as C1, C2,.

  In this key name process, since the LED 29 is always in a light emitting state, it is preferable to use an infrared LED rather than a visible LED.

  In addition to the key name guide, for example, this key name process enables all finger light sensors 241 and modulates the light emission from the LED 29 of each key 22 with the pitch corresponding to each key 22. This makes it possible to perform music without actually operating the keyboard. That is, the user can listen to the musical sound via the earphone 243 only by bringing the finger close to the range where the light emission of the LED 29 can be received. A keyboard device 30 that does not actually have the key 22 can be realized simply by arranging the LEDs 29 at a predetermined interval, which is good for application.

  In the present embodiment, the light amount modulation circuit 27 is prepared for each key name. However, only one of the light amount modulation circuits 27 may be prepared and correspond to all key names by time division processing. In the above-described example, the LEDs 29 of all the keys 22 are caused to emit light. However, only the LEDs 29 of some of the keys 22 may be caused to emit light to execute the key name guide. In this case, for example, only the key name of the mid-range key 22 may be guided, or the key name guide may be executed using only the key corresponding to each C sound.

  FIG. 5 is a block diagram of LED control in the performance guide process according to the embodiment of the present invention.

  The performance guide process according to the present embodiment is a process for causing the user to recognize a key to be played and a finger to be used for the performance in a state where the user cannot see the keyboard 30.

  In this process, when the user wearing the attachment 24 (FIG. 1) touches or approaches the finger 22 to the key 22, the light sensor 241 detects light modulated by the sound signal of the LED 29, and guides the user to the sound. It is something that lets you hear.

  The guide voice generation circuit 25 generates a guide voice corresponding to the key 22 designated by a note number or the like in accordance with an instruction from the CPU 9. For example, when the C3 key is designated by the note number, the voice signal corresponding to the key name of the designated key, such as “This is do”, is stored in the ROM 8 or the external storage device 15 as the voice signal. It is repeatedly generated by periodically reading out audio data (waveform data). Alternatively, the guide voice may be generated by reading out the guide voice stored as waveform data in the performance data. Note that a voice signal may be generated using a well-known voice synthesis method instead of reading the waveform data. Further, the key name guide voice is not limited to the above-mentioned method of calling with the fixed door, but may be called with the moving door after judging the adjustment of the music, or may be the pitch name (see, sea sharp ...). . Further, a musical tone having a pitch corresponding to each key may be output with the currently set tone color, or a key name may be generated with the pitch of each key. Furthermore, a voice that indicates where the C key is, such as C1, C2,... May be used. As will be described later, in this embodiment, only the optical sensor 241 corresponding to the finger to be operated is validated by a control signal from the CPU 9, but the name of the finger to be operated may be included as the guide voice. .

  A guide sound signal corresponding to the key 22 specified by the note number or the like generated by the guide sound generation circuit 25 is sent to the light amount modulation circuit 27. The light intensity modulation circuit 27 modulates the power supply voltage with the supplied guide voice signal and sends it to the LED signal allocation circuit 28. The LED signal allocation circuit 28 uses the received modulation voltage as a note number based on the control signal from the CPU 9. It is supplied to the LED 29 of the key 22 which has been done.

  In this way, light that is light-modulated by an audio signal of a key name or the like is emitted from the LED 29 corresponding to the note number designated by the fingering event of the performance guide data. Further, only the optical sensor 241 of the attachment 24 worn by the user is effective for the finger to be depressed. When the finger to be pressed by the user approaches the range where the light from the LED 29 can be received, the user can demodulate the light from the LED 29 detected by the optical sensor 241 and listen to the performance guide voice. For example, when the key designated by the note number is C3 and the designated finger is the thumb, light whose light amount is modulated by an audio signal such as a key name is emitted from the LED 29 corresponding to C3. At the same time, only the optical sensor 241 corresponding to the thumb is enabled. Therefore, the voice guide cannot be heard when the user brings a part other than the thumb close, but the voice guide can be heard only when the thumb is brought close. Thus, it can be seen that the user plays the C3 key with the thumb.

  When the name of the finger to be played is heard as a voice guide at the same time as the key name, all the optical sensors 241 may be always enabled because the finger to be played is known by the voice guide.

  FIG. 6 is a flowchart showing the reproduction start process according to the embodiment of the present invention. This process is started when the user instructs the start of reproduction of the automatic performance data with the panel operator 12. It is assumed that the automatic performance data has been read into a reproduction buffer area such as the RAM 7 in accordance with the above reproduction start instruction.

  In step SA1, playback start processing is started. In step SA2, the current playback position (current playback position) is set to the beginning of the automatic performance data.

  In step SA2, interruption of a performance guide process described later is permitted. Thereafter, the process proceeds to step SA4, where the reproduction start process is terminated.

  FIG. 7 is a flowchart showing the performance guide processing according to the embodiment of the present invention. This process is periodically started by a timer interrupt. In this example, it is assumed that the automatic performance data is SMF format MIDI data, and the fingering event is stored in the automatic performance data in the system exclusive (SysEx) format. In particular, it may be stored in the form of lyrics text as a lyric meta event. Further, the automatic performance data may be a message flow (stream) obtained from the MIDI device 17 via the MIDI interface 16 in addition to reading data stored in advance in the ROM 8 or the external storage device 15. . Also, the fingering event may be automatically generated from note-on and note-off events in addition to those previously embedded in the automatic performance data.

  In step SB1, performance guide processing is started, and in step SB2, the current playback position is recommended for a predetermined time. The predetermined time here is, for example, the same time as the interruption period of the performance guide process.

  In step SB3, it is determined whether or not the end of the automatic performance data has been reached. If the end of the automatic performance data has been reached, the process proceeds to step SB4 indicated by a YES arrow, prohibits the subsequent interrupt processing, proceeds to step SB15, and ends the current performance guide process. If the end of the automatic performance data has not been reached, the process proceeds to step SB5 indicated by a NO arrow.

  In step SB5, it is determined whether or not there is an event that has reached the playback time in the automatic performance data read into the playback buffer. If there is an event that has reached the playback time, the process proceeds to step SB6 as indicated by an arrow of YES, and if there is no event that has reached the playback time, the process proceeds to step SB15 as indicated by an arrow of NO, and this performance guide process is terminated. .

  In step SB6, one event is extracted from the automatic performance data in the reproduction buffer. In step SB7, it is determined whether or not the event extracted in step SB6 is a fingering event. If it is a fingering event, the process proceeds to step SB8 indicated by an arrow of YES, and if it is not a fingering event, the process proceeds to step SB9 indicated by an arrow of NO.

  In step SB8, the sensor switching circuit 244 is instructed via the attachment I / F 23 to switch the attachment 24 corresponding to the finger specified by the note number in the fingering event extracted in step SB6 to the optical sensor 241. With this process, only the optical sensor 241 corresponding to the finger indicated by the fingering event is enabled, and the other optical sensors 241 are disabled. Therefore, the user can recognize which finger should be played. Thereafter, the process returns to step SB5.

  In step SB9, it is determined whether or not the event extracted in step SB6 is a note-on event of a melody part (or a part for which the user wants a performance guide). If it is a note-on event, the process proceeds to step SB10 indicated by an arrow of YES, and if it is not a note-on event, the process proceeds to step SB12 indicated by an arrow of NO.

  In step SB10, the LED signal allocation circuit 28 is instructed to switch to the LED 29 corresponding to the key 22 specified by the note number in the note-on event extracted in step SB6 via the bus 6.

  In step SB11, the guide voice generation circuit 25 is instructed to generate the guide voice corresponding to the key 22 specified by the note number in the note-on event extracted in step SB6 via the bus 6. In response to this, the guide sound generation circuit 25 reads the guide sound from, for example, the ROM 8 or the external storage device, and sends it to the light intensity modulation circuit 27 as a sound signal. The voltage modulated by the light amount modulation circuit 27 is sent to the LED 29 switched by the LED signal control circuit 28, and the LED 29 is caused to emit light by the voltage modulated by the audio signal. Thereafter, the process proceeds to step SB14.

  In step SB12, it is determined whether or not the event extracted in step SB6 is a note-off event of a melody part (or a part for which the user wants a performance guide). If it is a note-off event, the process proceeds to step SB13 indicated by a YES arrow, and if it is not a note-off event, the process proceeds to step SB14 indicated by a NO arrow.

  In step SB13, the LED signal assigning circuit 28 is instructed to turn off the LED 29 corresponding to the key 22 specified by the note number in the note off event extracted in step SB6 via the bus 6. Thereafter, the process proceeds to step SB14.

  In step SB14, other processing is performed. Other processes include, for example, playback of parts other than the melody part (or the part for which the user wants a performance guide), pronunciation processing of each part (depending on the setting in the case of a melody part or a part specified by the user), , And other event processing (tone color change, volume change, tempo change, lyrics display, etc.). Thereafter, the process returns to step SB5.

  As described above, according to the embodiment of the present invention, an LED is installed in each key, and the sound signal corresponding to the key name is emitted from the LED, thereby extracting and amplifying the sound signal from the optical sensor attached to the finger. And you can listen to the sound from the keyboard with earphones. Therefore, it is possible to recognize the note name of the keyboard without looking at the keyboard.

  Further, according to the embodiment of the present invention, an LED is installed on each key, and a sound carrying a performance guide audio signal is emitted from the LED, thereby extracting and amplifying the audio signal from the optical sensor attached to the finger. You can listen to the performance guide sound from the earphones. Therefore, it is possible to receive a performance guide without looking at the keyboard.
