Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an electronic musical instrument, and more particularly, to an electronic musical instrument that can selectively select either a two-piano action function or an automatic key drive function, or in addition to the two-piano action function and an automatic key drive function. The present invention relates to an electronic musical instrument that can obtain a key touch feeling with a strength corresponding to the intensity of the touch in real time and with high precision.

[Conventional technology]

In recent years, with the rapid development of electronic technology, it has become possible to electrically synthesize a wide variety of square-colored musical tones. Electronic musical instruments that can freely produce synthesized musical tones have been developed. It also comes with a so-called piano action function that allows you to achieve a key touch feeling similar to that of natural SI instruments (e.g. piano), which is light at the beginning, heavy in the middle, and then light again at the end. I don't know the m-board instruments.
(For example, Japanese Patent Publication No. 1-39118) 4 However, the conventional S with this type of piano action function
The 6th board instrument uses a mechanical structure to create a key touch that feels solid at the beginning, heavy in the middle, and then light again at the end. For this purpose, for example, as the key press time elapses, the f! It has been impossible to obtain in real time a complex and highly accurate key touch response that is extremely heavy after the key is pressed, especially at each key press stroke position. Therefore, the present inventor has recently proposed an electronic keyboard musical instrument that can obtain a key touch feeling of a preferable intensity depending on the key depression operation position in real time and with high precision. On the other hand, keyboard instruments with a so-called automatic key drive function are known, which automatically drive the keys as the music progresses.

[Problem to be solved by the invention]

As described above, keyboard instruments with a piano action function and electronic keyboard instruments with an automatic key drive function have been known. However, 5 conventional electronic keyboard instruments of this type cannot selectively obtain both the piano action function and the automatic key drive function using a common key drive element; The problem is that even though the key touch feeling differs depending on the instrument, that is, the tone used (for example, the key touch feeling is different between the tone of a piano and the tone of a harpsichord), only the same key pitch and tone are obtained. had] - had. An object of the present invention is to provide an electronic musical instrument in which either a piano action function or an automatic key drive function can be selectively selected. In addition to this, it is an object of the present invention to provide an electronic musical instrument that can accurately obtain in real time a key touch intensity that corresponds to a selected timbre.

[Means to solve the problem]

In order to achieve the above object, the electronic musical instrument according to the invention as set forth in claim 1 includes a key to be pressed, a mode setting means for selectively setting an automatic key performance mode and a manual key performance mode; When automatic key performance is started with the automatic key performance mode set by the mode setting means, the keys are automatically driven one after another according to a preset order; Under the state in which the manual key performance mode is set by the mode setting means,
The apparatus includes a key drive control means that applies a preset key braking force to the key at each position of the key depression when the key is depressed. Further, in order to achieve the above object, the electronic musical instrument according to the invention according to claim 2 selectively sets keys to be pressed, tone setting means, automatic key performance mode and manual key performance mode. When automatic key performance is started under the condition that the automatic key performance mode is set by the mode setting means, the keys are automatically played one after another according to a preset order. On the other hand, when the manual key performance mode is set by the mode setting means and a predetermined timbre is set by the timbre setting means, the key press operation is performed. When the key is pressed, for each position of the key press displacement,
The key drive control means applies a preset key braking force in accordance with the set tone color. Furthermore, in the electronic musical instrument according to the invention as set forth in claim 2, when the key press displacement position of the key according to claim 1 or 2 exceeds a set position, in response to this, a sound indicating the pressed key is generated. The apparatus further includes musical tone generating means for generating a musical tone having a pitch corresponding to the high pitch. The key drive control means includes, for example, a key press displacement detecting means for detecting a press displacement of the key, and a preset key braking function for each key press displacement detected by the key press displacement detecting means. Consisting of a key braking signal generating means that generates a signal, and a key braking force applying means that applies a key braking force to the key every time the key is pressed based on the key braking signal generated from the key braking signal generating means. This is what I did. Alternatively, the key drive control means may be configured to include, for example, a key press displacement detecting means for detecting a press displacement of the key, and a set tone color for each key press displacement detected by the key press displacement detecting means. a key braking signal generating means for generating a key braking signal set in advance; and a key braking force is applied to the key each time the key is pressed based on the key braking signal generated from the key braking signal generating means. This is constructed by a key braking force applying means. Further, a key press displacement to needle brake signal converting means converts the key brake signal generating means into a preset key brake signal for each key press displacement detected by the key press displacement detecting means and outputs the signal. It is preferable to configure the following. Alternatively, the key braking signal generating means converts and outputs a key braking signal that is preset according to a set tone color for each key press displacement detected by the key press displacement detecting means. Preferably, the key press displacement to needle braking signal converting means is used.

[Effect]

According to the invention set forth in claim 1, when automatic key performance is started in a state where the automatic key performance mode is set by the mode setting means, the preset order is set by the key drive control means. automatically drive the keys in sequence according to the
On the other hand, when a key is pressed in a state where the manual key performance mode is set by the mode setting means, the key drive control means causes the key to be pressed at each position of the pressed key. Since a preset key braking force is applied to the keys, a common key drive control means is used to selectively realize either the piano action function or the automatic key drive function. I can do it. Further, according to the second aspect of the invention, when automatic key performance is started in a state where the automatic key performance mode is set by the mode setting means, the key drive control means:
The keys are automatically driven one after another according to a preset order, while the manual key performance mode is set by the mode setting means, and a predetermined tone is set by the tone setting means. When a key is pressed, the key drive control means applies a key control that is preset for the key according to the set tone color for each position of the key press. Since it is designed to apply power, it is not only possible to selectively realize any of the via, no action, and automatic key drive functions using a common key drive control means, but also the piano action 11 ! A manual key performance mode has been set to realize i-functions. It is possible to obtain the corresponding strength of tsutasotchi feeling in real time and with high precision. Furthermore, according to the invention recited in claim 3, when the manual key performance mode is set by the mode setting means and the key press displacement position exceeds the set position, in response to this, - , a musical tone with a pitch corresponding to the pitch corresponding to the pressed key is generated, so the piano
While realizing the arcsion function, it is possible to generate the desired musical tone from the point at which the displacement position caused by pressing the key exceeds the set position, so it is possible to obtain key operation conditions and sound production conditions that are close to those of a natural keyboard instrument. can.

The key touch data and mode selection data output from the keypad switch section 1 and mode selection switch section 2 are
Sent to U3. When the tone selection switch 4 selects a tone, the CPU 3 uses the tone selection data to set the tone of the musical sound generation port i5, and when playing, it detects the key touch from the key touch detection/current control section 12. According to the data signal, command data, etc. for starting sound generation and frequency control are sent to the musical sound generation port '#r5 to activate the internal sound generation channel to generate a musical sound signal, and at the same time, according to the key touch data, the tone, etc. In order to control the volume, the data is sent to the voltage signal generation circuit 6. The voltage signal output from this voltage signal generation circuit 6 is VCF (7F voltage controlled filter), VCA8

The volume is controlled and the sound is emitted in red from the sound system's amplifier 9 and speakers] 60. In this example, m of the above-mentioned basic keyboard electronic musical instrument is
In addition, a touch curve conversion memory 11 includes a plurality of touch curve conversion tables that are selected based on the tone selection information of the tone selection switch 4, and a specific touch curve conversion table within this touch curve conversion memory 11. a key touch detection/current control unit 12 as a key drive control means that applies a braking force (reaction force) to the pressed key 20 using a magnetic force method according to the read key braking force signal;
An electromagnet section 13 including a first electromagnet section 13A and a second electromagnet section 13B is provided. When this electromagnet section 13 outputs a key touch signal that equally indicates the pressed key/N key state and touch speed (time difference) of the keystone switch section 1, this key touch signal is transmitted to the key touch detection and current control section 12. The key touch detection and current control section 12 sends key touch data such as a key code signal indicating the pitch of the pressed key 20 and touch response data indicating the touch speed to the CPU 3. The plurality of touch curve conversion tables in the touch curve conversion memory 11 are selected by the tone color selection switch 4, and have contents as shown in FIGS. 4(A) to 4(C), for example. That is, FIG. 4(A) shows, for example,

It is a characteristic diagram showing key touch anger. In this case, each horizontal axis represents the key press stroke (key press position) of the key 20, and the vertical axis represents the reaction force (key driving force).
In the case of C), according to the key press stroke of the key 20 (key 20
As the key 20 is pushed in deeper), a key driving force (reaction force) acts linearly on the key 20. Reference numeral 14 denotes a music data ROM for outputting data of music to be performed during automatic key performance;

Reference numeral 15 denotes a moving current supply device for supplying moving current to the electromagnet section 13 for moving the key 2o necessary during automatic key performance. Including a configuration example of the electromagnet section 13 that generates this variable magnetic force,
The mechanism around the key is illustrated in FIG. In the same figure, 2
0 is a key, and 21 is a frame or chassis of the main body of the musical instrument. The key 20 is horizontally balanced with respect to the main body chassis 21 by coil springs 28A and 28B around two supporting members. this! ! ! 20 is a normal position (upper limit position) where the stopper member 22 shown in FIG. is able to swing between a lower limit position where it abuts against a buffer member 22b provided on the horizontal surface of the main body chassis 21. Then, after the start of the key press stroke of the key 20 (when the key is pressed), the key 20
A pair of pressing parts 23 and 24 projecting downward from the main body of the
When the rubber switches 26 and 27 formed on the printed circuit board 25 fixed to the main body chassis 21 are successively abutted, pressed and deformed, a pair of movable electrical contacts (Fig. (not shown) sequentially come into contact with a pair of fixed contacts (not shown) on the printed circuit board 25, thereby generating the above-mentioned key code signal and key switch signal for forming key touch data. As the key is pressed, the coil spring 28A provided close to the two support members of the key 20 is expanded, and the coil spring 28B is compressed. Further, an electromagnet 13 constituted by a first electromagnet section 13A and a second magnet section 13B is fixed to the opposite end of the key 20 from the pressing side. This electromagnet 13 constitutes a key drive control means that generates variable attractive force and repulsive force between the key 20 and the main body chassis 21, and has a configuration as shown in FIG. 3. That is, 30 is a first coil, which is wound around the core 31. 32 is a second coil, which is wound around the core 33. This first coil 30, core 31,

The magnetic member 36 constitutes a first magnet portion 13A. Further, the second coil 32 and the second magnetic member 37 constitute a second electromagnet section 13B. Further, three mounting members are fixed to the tip of the solenoid 1 plunger 38, and the tip of the solenoid plunger 38 is rotatably attached to the pin 40 via these three mounting members.
It is attached to the key 20 by. This first electromagnet section 13A is configured to move the solenoid plunger 38 in the +-down direction by the action of the first coil 30 excited by the supplied key braking signal under the manual key performance mode setting. belongs to. Further, under the setting of the automatic key performance mode, the second electromagnet section 13B has a second electromagnet section excited by the supplied key driving force signal.
The action of the coil 32 causes the solenoid plunger 38 to
On the other hand, when the manual key performance mode is set, the solenoid plunger 38 is used to generate an induced voltage corresponding to the amount of upward movement of the solenoid plunger 38. Next, the operation of this embodiment will be explained using the operation flowcharts shown in FIGS. 5 and 6. [Automatic Key Performance Mode] FIG. 5 shows an operation flowchart of the automatic key performance mode. When the mode selection switch section 2 is set to automatic key performance mode, an automatic key performance operation is performed. First, in step 100, when the automatic performance mode is set, in step 110, the CPU 3 reads pitch, duration, and key drive data from the music data ROM 14. Next, in step 120, the music data R
Based on the key drive data read from OM14, the CP
Based on the command from U3 to the moving current supply device 15 to output a command signal for supplying the electromagnet section 13 with a moving current necessary for keeping the key 20 in place during automatic key performance, the moving current supply device 15: Second electromagnet part 1

The solenoid plunger 38 of the key 20 corresponding to the pitch data read from the key 20 is driven upward. When the solenoid plunger 38 is driven upward in step 120, 1!20 rotates clockwise in FIG. .24 is each rubber switch 2
6. Press 27. For this reason, these rubber switches 2
In step 130, touch response data corresponding to the time when the solenoid plunger 38 is sequentially turned on is generated. Therefore, in step 130, this touch response data is sent to the tone generation circuit 5, and the key-on data generated at the timing when the rubber switch 27 is turned on instructs the start of sound generation. Further, in step 140, other processing is performed, and in step 150, it is determined whether or not the tone duration indicated by the read musical tone data has elapsed. In this step 150, if the sound duration has not elapsed,
Return to step 140. If it is determined in step 150 that the tone duration has elapsed, then in step 150 the next automatic performance data is read out, and in step 170 it is determined whether the music piece has ended. Step 170
If it is determined in step 170 that the music has not ended, the process returns to step 110, and if it is determined in step 170 that the music has ended, this flow ends (step 180).
). In this way, in this automatic key performance mode setting, the key 20 indicated by the pitch data read out from the music data ROM 14 is played in accordance with the read out key drive data.
6 [Piano Action Mode] which is automatically driven by the drive of the second electromagnet section 13B FIG. 6 shows an operation flowchart of the piano action mode (manual key performance mode). When the mode selection switch section 2 is set to the piano action mode, the piano action mode operation is performed. First, in step 200, when the key 20 is pressed while the piano action mode is set, [20 is rotated using the two support members as pivot points in FIG.
As it rotates clockwise, the solenoid plunger 38 connected to the end of the key 20 will move upward. Then, the permanent magnet 35 fixed to the solenoid plunger 38 similarly moves upward, so that an induced voltage corresponding to the amount of movement is output from the second coil 32. The key touch detection lIt current control section 12 detects this lick, the key press position of the key 20, and the depth of the press. Then, in step 210, the solenoid 7 is activated by the movement of the key 20 based on the key depression.
From the movement of the plunger 38, the key press position and key press speed of the pressed key 20 are detected by the flow control unit 12 using the key touch detection lid. Thereafter, in step 220, it is determined whether or not musical tone #20 is being generated, and if it is being generated, the process moves to step 240, which will be described later. Further, if it is determined in step 220 that the sound is not being generated, in step 230, the key touch detection lid 1
The touch response data corresponding to the key press speed detected by the PfIJ control unit 12 and the pitch data corresponding to the key are transferred to the musical sound generation circuit 5, and the key press displacement position of the key 20 is set to the set position. The instruction to start pronunciation is given at a timing exceeding this point. Next, as described above, the pressed position of the key 20 is detected by the key touch detection and current *J# section 12, and the induced voltage (or corresponding take) corresponding to this pressed position is Since it is sent to the touch curve conversion table selected in advance by the timbre selection switch 4, in step 240, the key driving force data corresponding to the key press position 1120 is sent to the key touch detection and detection table from the touch curve conversion table. It will be sent to the current control section 12. Therefore, the drive of the first electromagnet section 13A corresponding to the pressed key 1I20 is controlled. Therefore, due to the magnetic attraction force of the first electromagnet portion 13A, the permanent magnet 35 is drawn downward with a key driving force corresponding to the key pressed position. Therefore, since the solenoid plunger 38 is pulled in the same direction, j12
0 rotates counterclockwise in FIG. 2 using the support member 29 as a rotational fulcrum, and as a result, a key reaction force is applied to the key 20 that is being pressed, and as a result, the key 20 corresponds to the key pressing position. You can get evil by touching the key. On the other hand, if the musical tone is already being generated in step 220, it is not necessary to start generating the musical tone (step 230), so the process proceeds to step 240, in which the key 20 is activated based on the key drive data corresponding to the pressed key position. Gives key driving force to. In this way, after starting to produce musical tones, steps 210, 220, and 240 are sequentially performed.
A corresponding key driving force is applied to the key 2o for each key depression position. Further, in step 250, it is determined whether or not the power is turned off, and if the power is turned off, this flow is ended. FIG. 7 shows another embodiment of the electronic musical instrument according to the present invention. In the figure, 50 is a first magnet part, which is composed of a coil 50A and a permanent magnet (or magnetic material) 50B.
When the key 20 is pressed under the manual key performance mode setting, the key pressing position and key pressing speed of [20] are detected. A key press position/key press speed detection circuit 52 is connected to the first electromagnet section 50 . This key press position/key press speed detection circuit 52 constitutes key press displacement detection means for detecting the press displacement of the key 2o. 51 is a second electromagnet section, and a coil 5
1A and a permanent magnet (or magnetic material) 51B, and when the automatic key performance mode is set, the key 20 is automatically driven in accordance with the progress of the music. When the manual key performance mode is set, key driving force is applied to g120 in accordance with key driving force data generated based on the first electromagnet section 50. A key drive circuit 53 is connected to the second electromagnet section 51 . This second electromagnet portion 51 constitutes a key driving force applying means and an automatic key driving means. This second electromagnet section 51 operates in manual key performance mode (piano/key performance mode).
action mode), the key drive circuit 5 is activated according to performance conditions such as tone stored in the touch curve conversion memory 11 or by a braking force signal based on the y curve.
Controlled by 3. The rest is the same as the embodiment shown in FIG. 8 and 9 show examples of general touch curves stored in the touch curve conversion memory 11. The touch curve shown in Fig. 8 represents the reaction force F, which is the key driving force applied to the key 2°, felt by the finger according to the key depression position (X), and the touch curve shown in Fig. 9 For the curve, key 2o is at position X. After pressing up to that position X. It represents the reaction force F that you feel when you press a key while accelerating. Note that each of the touch curves a to a represents the relationship between the key press position <X) and the reaction force (F) corresponding to the selected tone color. According to this embodiment, it is possible to obtain a key touch feeling based on the touch data shown in FIGS. 8 and 9.
