Description

  The present invention relates to a tone generation instruction device, a tone generation instruction method, and a program.

  In a musical tone generator such as a conventional electronic keyboard instrument, the pitch of a musical tone to be pronounced is specified by pressing one of the keys on the keyboard, which is a performance operator, and the specified sound is specified. A high tone is generated by a sound source, and the generated tone is generated by a connected speaker or headphones.

When playing a predetermined tune using such an electronic keyboard instrument, a performer often performs a trial performance in order to confirm the state of the electronic keyboard instrument.
In particular, when the prepared electronic keyboard instrument is the first performance for the performer, it is necessary to perform in advance because the tone of the musical sound that is generated and the sense of actual performance cannot be grasped. It was.

However, there are cases where such a trial performance cannot be performed sufficiently. This is the case where there is an environment in which it is not preferable to produce sound, for example, when there are other viewers.
In such a case, it is conceivable to switch the sound so that the sound is generated from the headphones instead of the sound from the speaker. Conventionally, an electronic keyboard instrument that can be switched to sound by either the speaker or the headphones has been proposed. ing.

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

[First Embodiment]
FIG. 1 is a block diagram of an electronic keyboard instrument as a musical sound generation instruction device according to the first embodiment of the present invention.
The operation unit 1 includes a keyboard unit 10 and a touch / proximity sensor 11. The touch / proximity sensor 11 is provided on each key of the keyboard unit 10.

FIG. 2A shows a part of a plurality of keys in the keyboard unit 10, and FIG. 2B is a side view of keys represented by En among these keys.
One end of the key En is fixed to a key support member 20 provided in the electronic keyboard instrument case, and when the key En is depressed, the key En is pushed downward about a fulcrum fixed to the key support member 20. .

The rubber SW 21 is disposed below the key En. When the key En is depressed, the conductor 22 (carbon or the like) incorporated therein is disposed on the PCB 23 disposed below the rubber SW 21. Then, it comes into contact with the comb-like counter electrode 24 (carbon or the like), and the SW 21 is turned on. As a result, it is determined that the key En has been pressed.
Further, a touch / proximity sensor 11, for example, a SENSING PLATE / PATTERN for a capacitance sensor, is disposed below the upper surface of the key En.

Returning to FIG. 1 again, the outputs of the keyboard unit 10 and the touch / proximity sensor 11 are supplied to the tone generator / control LSI 2. The sound source / control LSI 2 periodically supplies a scanning signal to the operation unit 1 via the output line 3, and thereby the state of the rubber SW 21 and the touch / proximity sensor 11 provided for each key of the keyboard unit 10. The signal representing is taken in.
Accordingly, when the rubber SW 21 of any key is turned on or when the touch / proximity sensor 11 detects a touch, a musical tone signal having a pitch corresponding to the key is generated. The generated tone signal is supplied to the SP amplifier 4 for speakers and the HP amplifier 5 for headphones.

The speaker SP amplifier 4 and the headphone HP amplifier 5 are respectively supplied with mute signals MUTE1 and MUTE2 from the sound source / control LSI 2.
When the mute signal MUTE1 is "H", the HP amplifier 5 is muted (stopped), and when it is "L", it is active (operated). Similarly, when the signal MUTE2 is also “H”, the SP amplifier 5 is muted (stopped), and when it is “L”, it is active (operation).
The speaker SP amplifier 4 amplifies the supplied musical sound signal and supplies it to the connected speaker 6. On the other hand, the headphone HP amplifier 5 similarly amplifies the supplied musical sound signal and supplies it to the output terminal into which the jack of the headphone 7 is inserted.

This output terminal is provided with a headphone insertion detector 8 for detecting whether or not a jack of the headphone 7 is inserted, and this detection signal is supplied to the sound source / control LSI 2. When the detection signal indicates that the headphone 7 jack is not inserted, the sound source / control LSI 2 sets the mute signal MUTE1 to “H” and mutes (stops) the HP amplifier 5.
A display unit 9 is connected to the sound source / control LSI 2.

FIG. 3 is a flowchart showing the processing operation of the sound source / control LSI 2.
Here, in the initial state, it is assumed that the jack of the headphone 7 is inserted into the output terminal, and the signals MUTE1 and MUTE2 are both “H”.

First, it is determined whether or not the touch / proximity sensor 11 provided on any key of the keyboard unit 10 has detected a touch operation (step S1). If NO is determined here, the process of step S1 is repeated.
On the other hand, if “YES” is determined here, the signal MUTE1 is set to “L”, and the signal MUTE2 is set to “H” (step S2). When the signal MUTE1 becomes “L”, the headphone HP amplifier 5 becomes active, and a musical sound signal is supplied to the headphone 7 inserted in the output terminal.

On the other hand, when the signal MUTE2 becomes “H”, the speaker amplifier 4 is muted, and the generated tone signal is not supplied to the speaker 6.
In this way, when a touch operation is performed on a desired key, a musical sound can be generated only from the headphones 7.

Subsequent to step S2, the process proceeds to step S3, where it is determined whether or not any key is pressed and the rubber SW 21 below the pressed key is turned on. If NO is determined here, the process returns to step S1.
If YES is determined, the signal MUTE2 is set to “L”, the SP speaker 4 is activated, and the process returns to step S3.

As a result, after a touch operation on the key, if a key pressing operation is performed on the key, the generated musical sound is also generated from the speaker 6.
As described above, in the present embodiment, a tone signal is generated by simply touching the key without pressing the key, but the generated tone signal is not generated from the speaker 6 and only the headphones 7 are generated. Will be pronounced.
For this reason, for example, when it is a trial performance, if you do not want to let people hear you much or want to disturb people around you, you can hear the performance only from the headphones 7 by lightly touching the desired key. This eliminates the need to insert / remove or switch the troublesome headphone jack.

[Second Embodiment]
In the first embodiment, when a key is touched, a musical sound signal is generated and sounded from the headphones 7. In the second embodiment, instead of sounding from the headphones 7, a display unit is generated. The note display corresponding to 9 is performed.
FIG. 4 is a flowchart showing the processing of the sound source / control LSI 2 in the second embodiment. Here, the same configurations and processing operations as those of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

If it is detected in step S1 that a touch operation has been performed with any of the keys, the process proceeds to step S5, and a note having a pitch corresponding to the key is displayed on the display unit 9. Thereafter, the process proceeds to step 3 to determine whether or not there is a key pressing operation.
In this way, by performing a touch operation on a corresponding key in accordance with a certain piece of music, notes based on the operation are sequentially displayed on the display unit 9. As a result, the performer can confirm whether or not his / her performance is being performed correctly without producing any sound, and can practice the performance without disturbing others.

[Third Embodiment]
In the third embodiment, it can be confirmed by touching a desired key whether or not a performance is correctly performed according to model music data prepared in advance.

FIG. 5 is a block diagram of an electronic keyboard instrument in the third embodiment.
In the third embodiment, in addition to the configuration shown in FIG. 1, the LED 30 provided corresponding to each key, the LED control driver 31 for driving them, and guide data corresponding to the model music are stored. A guide data memory 32 is added.

FIG. 6 is a side view of the key represented by the key En in the third embodiment.
What is characteristic here is that each key is made of a material having a high light guide rate, and further, an LED 30 is provided below the key. As a result, when the LED 30 is turned on, the entire key can be illuminated.
In FIG. 5, the description of the rubber SW21 is omitted.

FIG. 7 is a flowchart showing the processing of the sound source / control LSI 2 in the third embodiment.
First, the next data representing the next key to be operated is read from the guide data memory 32 (step S40). Subsequently, the LED 30 that is already lit is extinguished (step S41).

Thereafter, it is determined whether or not any key is touched (step S42). If the determination is NO, the process returns to step S41. On the other hand, if the determination is YES, the process proceeds to step S43, and it is determined whether or not the key indicated by the next data read previously matches the key detected by the touch operation.
If they do not coincide with each other, the LED 30 corresponding to the key indicated by the next data is turned on (step S44), and then the process returns to step S42 again.

On the other hand, if they match, the lit LED 30 is turned off (step S45), and the process proceeds to step S46. Here, it is determined whether one of the keys is pressed, that is, whether one of the rubber SWs 21 below the key is on.
If YES, that is, if a key pressing operation is performed, a musical tone signal corresponding to the key being pressed is generated, and the generated musical tone signal is supplied to the speaker 6 via the SP amplifier 4 ( Step S47). Then, the process returns to S40 again.
On the other hand, if no key pressing operation has been performed, the process returns to S41.

In this way, when practicing playing a model tune prepared in advance, if an incorrect key that does not match the model tune is touched, the correct key is lit to notify that an erroneous operation has occurred. For this reason, it is possible to perform performance practice without making a sound, and it is possible to practice without disturbing the surrounding people.
In the present embodiment, the key indicated by the next data is turned on / off, but the key that has been touched may be turned on / off.

[Fourth Embodiment]
In the third embodiment, the corresponding key is turned on when the key indicated by the model performance song does not match the touched key. In the fourth embodiment, the corresponding key is turned on. It is characterized by vibrating instead.

FIG. 8 is a block diagram of an electronic keyboard instrument in the fourth embodiment.
In the fourth embodiment, a vibration element 40 such as a motor is added in addition to the configuration shown in FIG.

FIG. 9 is a side view of the key represented by the key En in the fourth embodiment.
Compared to FIG. 6 representing the third embodiment, the difference is that the vibration element 40 is provided on the fulcrum of each key. The vibration of the vibration element 40 also vibrates the key itself, and transmits this vibration to the performer's finger.
FIG. 10 is a flowchart showing the processing of the sound source / control LSI 2 in the fourth embodiment.

  The flowchart shown in FIG. 10 basically performs the same processing as the flowchart of the third embodiment shown in FIG. However, in steps S41 and S45 in FIG. 7, the process of turning off the lit LED 30 is performed, but in steps S50 and S51 corresponding to this in FIG. 10, the process of stopping the vibration of the vibration element 40 is performed. . Further, in step S44 in FIG. 7, the process of turning on the LED 30 that has been turned off is performed, but in step S52 corresponding to this in FIG.

As described above, in the fourth embodiment, when practicing a model tune prepared in advance, if a wrong key that does not match the model tune is touch-operated, the key pressed is vibrated to cause an erroneous operation. I can inform you. For this reason, it is possible to perform performance practice without making a sound, and it is possible to practice without disturbing the surrounding people.
In the fourth embodiment, when a wrong key is touch-operated, not only the operated key is vibrated, but the erroneously operated key or the correct key may be lit.
