DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch response device, and more particularly, to a touch response device for controlling a touch response based on the operation speed and operation intensity of a performance operator.

[0002]

2. Description of the Related Art Electronic musical instruments and the like are provided with a touch response device for reflecting a key pressing speed (operation speed) and a key pressing force (operation intensity) of a key, which is a performance operator, in a musical tone.

The conventional touch response device counts the time from the start of operation of the switch means linked to the key operation to the end of the operation with a clock, and outputs the measured value as touch data. Then, based on the touch data, the electronic musical instrument or the like changes the volume or tone of the musical sound and emits the sound.

Therefore, an electronic musical instrument, etc., provided with such a touch response device, detects touch data corresponding to the key operation speed and operation intensity, and reproduces a musical sound corresponding to the key operation feeling with good reproducibility. Can be generated.

[0005]

However, in such a conventional touch response device, in the case of a skilled player who can operate the key pressing speed and the key pressing intensity with all fingers at will. By changing the key operation, a musical tone corresponding to the operation feeling can be generated with good reproducibility. However, when performing the key operation using a plurality of fingers, the key pressing speed and the If you are a beginner whose key depression strength is not as desired, you can perform musical operations of the same volume and tone with different fingers, for example, if the musical tone played with your thumb becomes loud, the musical tone played with your little finger is There is a problem in that the musical tone is generated as a musical tone having a different volume or tone that becomes a sound, and the musical tone intended by the player cannot be generated, making it difficult to perform.

Accordingly, the present invention provides a touch response device that corrects variation in touch data due to variation in operation of a performance operator to a uniform one even if the operation speed and operation intensity of the performance operator vary. It is intended to be.

[0007]

According to the present invention, a plurality of performance operators for designating a pitch of a musical tone to be generated, and an operation speed or operation intensity of an ON operation of each of the performance operators are provided according to the present invention. Touch data detecting means for detecting the touch data based on, and when any of the performance operators is newly turned on, determining means for determining whether there is another performance operator already on operation, When the determination means determines that the other performance operator is on operation, the touch data of the new performance operator and the touch data of the other performance operator detected by the touch data detection means. With the new performance control.

[0008]

[0009]

Furthermore, the touch response device, for example, as described in claim 2, a switching means for switching the whether to enable or disable the operation of said correcting means may be provided further.

[0011]

According to the above construction, the touch data detecting means detects the touch data based on the operation speed or the operation intensity of the on operation of the plurality of performance operators for designating the pitches of the musical tones to be generated. When the determination means determines that there is another performance operation element that is already being turned on when any one of them is newly turned on, the comparison means detects the touch data.

Therefore, when the performance operator is continuously turned on, the touch data of the newly operated performance operator is corrected based on the touch data of the other performance operator that was previously turned on. Therefore, even if there is a variation in the operation speed or the operation intensity of the performance operator, it is possible to correct the variation of the touch data due to the variation.

In this case, the touch data of the new performance operator is modified only when the difference between the touch data of the new performance operator and the touch data of another performance operator is within a predetermined range. However, if the player intentionally changes the operation speed or operation intensity of the performance operator, the touch data is not corrected, and if the operation of the performance operator varies, the touch data can be corrected. it can. Therefore, the touch data can be changed in accordance with the operation of the performance operator, and the variation in the operation of the performance operator can be corrected.

[0014]

Further, when switch means for switching between the operation of the correction means and the operation of the correction means are provided,
Depending on the level of skill of the player, it is possible to correct variations in the operation of the performance operators and to obtain changes in touch data according to delicate operations of the performance operators.

[0016]

The present invention will be specifically described below with reference to examples.

FIGS. 1 to 8 show an embodiment of the touch response device according to the present invention.

FIG. 1 is a block diagram of an electronic musical instrument 1 to which a touch response device is applied. The electronic musical instrument 1 includes a keyboard 2, a microcomputer 3, a tone / effect switching unit 4, a mode switching switch 5, and a tone generation circuit. 6 and musical sound output device 7
Etc. are provided.

The keyboard 2 has a plurality (for example, 72 keys) of keys (performance operators) 8, and the player operates the keys 8 to specify the pitch of a musical tone to be generated. Although not shown, the keyboard 2 is provided with a touch response detection device. The touch response detection device is the same as the conventional touch response detection device, and operates the key 8, particularly, presses the ON operation. A key speed or key depression strength is detected and output to the microcomputer 3 as touch data. The keyboard 2 outputs pitch data corresponding to the depressed key 8 to the microcomputer 3.

The timbre / effect switch unit 4 has a plurality of switches, and the player operates the switches of the timbre / effect switch unit 4 to add the timbre of the generated tone or the generated tone. Switch the effect and specify.

A predetermined constant voltage VDD is applied to the mode changeover switch 5. The mode changeover switch 5 performs a correction mode for correcting touch data (when the mode changeover switch 5 is on) and a touch mode correction. This is a switch for switching between a normal mode in which the operation is not performed (when the mode switch 5 is turned off).

The microcomputer 3 has a ROM (Read Only Memory).
y), RAM (Random Access Memory), etc.
By using M as a work memory, each section of the electronic musical instrument 1 is controlled according to a program in the ROM, and processing as the electronic musical instrument 1, particularly, touch data correction processing is performed. That is, the microcomputer 3 operates the timbre / effect switch unit 4 to correct the touch data according to the switch state of the mode switch unit 5 based on the touch data and the pitch data input from the keyboard 2. Thus, various tone information necessary for generating a tone is output to the tone generating circuit 6. In particular, the microcomputer 3 stores a mode flag register, a NEWKEY register, an OLDK
An EY register, a NEWTCH register, an OLDTCH register, a key-on flag register, an A register, a B register, and the like are provided. As will be described later, data is stored in these registers in the above-described processing and processing is performed.

The tone generator 6 generates a tone based on various tone information input from the microcomputer 3 and outputs the tone to the tone output device 7. The tone output device 7 includes an amplifier 9 and a speaker 10 and outputs the tone input from the tone generating circuit 6 in a louder manner.

Next, the operation will be described.

In order to perform a performance using the electronic musical instrument 1, first, each switch of the tone / effect switch unit 4 is operated to set the tone color of the generated tone and the effect to be added to the generated tone. In addition, the mode setting switch 5 is used to set a mode for enabling or disabling correction of touch data.

When the power is turned on, the electronic musical instrument 1
By performing the main processing shown in (1), a musical tone is generated according to the setting of the mode changeover switch 5.

That is, in the main process, when the power of the electronic musical instrument 1 is turned on, first, an initial process is performed.
Various registers and the like are initialized (step S1), and thereafter, a keyboard process (step S2) and a switch process (step S3) are sequentially repeated.

Next, the keyboard processing will be described with reference to FIG.

In the keyboard processing, first, each key 8 of the keyboard 2 is scanned (step S11), and it is checked whether a key change has occurred (step S12). When the key 8 is turned on, a key-on process is performed (step S13), and when the key 8 is turned off, a key-off process is performed (step S14). And if the key is not operated
do nothing.

In this key-on process, it is checked whether or not a mode flag set by the mode changeover switch 5 ("1" is set when correction of touch data is enabled) is "1" (step P1). If the mode flag is "0", it is determined that the mode is the normal mode, and the key code of the key 8 which has been pressed this time is stored in the NEWKEY register (step P13). Further, the touch data of the key 8 that has been pressed this time is stored in the NEWTCH register (step P14). Then, the key-on flag is set to "1" (step P15), and the key code of the NEWKEY register and the touch data of the NEWTCH register are output to the tone generator 6 to give a tone generation start instruction (step P11). The tone generation circuit 6 generates a tone based on the given key code and touch data, and causes the tone output device 7 to generate a tone.

That is, in the normal mode, the keyboard 2
The tone generation circuit 6 generates a tone using the detected touch data without modifying the touch data detected by the touch response detection device provided in the device.

In step P1, when the mode flag is "1", it is determined that the mode is the correction mode, and a key-on flag (whether all keys 8 are off) indicating whether or not there is a key 8 being turned on. Is sometimes set to “0”) is “1”
It is checked whether it is (Step P2). Step P2
When the key-on flag is "0", there is no key 8 currently being turned on before there is a key to be used as a reference for correcting the key 8 which has been pressed this time.
The key code and touch data of the key 8 that has been turned on this time are stored in the NEWKEY register and the NEWTCH register, respectively (steps P13 and P14), the key-on flag is set to "1" (step P15), and the tone generation circuit 6 (Step P11).

Therefore, even in the correction mode, when a key is depressed or there is no key 8 that has been previously turned on, the touch data detected as it is is used without correcting the touch data. The tone generator 6 generates a tone.

At step P2, when the key-on flag is "1", the key code of the NEWKEY register is set to "OLDK".
The key code of the key 8 that has been depressed this time is stored in the NEWKEY register (step P4). Then, the touch data of the NEWKEY register is stored in the OLDTCH register (step P5), and the touch data of the key 8 which is currently pressed is stored in the NEWTCH (step P6). The key code of these OLDKEY registers and
The key code of the NEWKEY register is stored in each of the registers A and B (step P7), and the absolute value of the difference between the key code data of the register A and the key code data of the register B is set to a predetermined value (this embodiment). Then
"3") is checked (step P
8).

When the absolute value is not larger than "3", the touch data of the OLDTCH register is stored in the register B and NE
The touch data of the WKEY register is stored in the register A (step P9), and the absolute value of the difference between the touch data of the register A and the touch data of the register B is set to a predetermined value (in this embodiment, "9"). ) Is checked (step P10).

When the absolute value is not larger than "9", it is determined that the touch data can be corrected.
The touch data of the OLDTCH register stored in the register B is stored in the NEWTCH register (step P1).
2). That is, the touch data of the key 8 that was previously turned on is set as the touch data of the key 8 that was turned on this time,
Store in CH register. Then, the touch data of the NEWTCH register and the key code of the NEWKEY register are output to the musical tone generating circuit 6, and the musical tone generating circuit 6 generates a sound (step P11).

Therefore, when the key 8 is depressed, it is checked whether there is a key 8 being depressed first, and if there is a key 8 being depressed, the sound of the key 8 being depressed is first. The pitch difference between the high pitch and the pitch of the currently pressed key 8 is within “3”, and the touch between the touch data of the previously pressed key 8 and the touch data of the currently pressed key 8 If the data difference is within “9”, the touch data of the currently pressed key 8 is corrected to the touch data of the currently pressed key 8 and the sound is generated.

On the other hand, if the absolute value of the difference between the key code data of the register A and the key code data of the register B is larger than "3" in step P8,
If the absolute value of the difference between the touch data of the register A and the touch data of the register B is greater than “9”, the judgment is made based on the tone characteristics such as pitch and touch data.
The key operation of the key 8 that was previously pressed and the key operation of the key 8 that was pressed this time are determined to use different touch data in terms of musical tone characteristics. , The key code and touch data of the currently pressed key 8, ie, the key code and NEWTCH of the NEWKEY register.
Is output to the musical tone generating circuit 6 to cause the musical tone generating circuit 6 to generate a sound (step P11).

Therefore, when the key 8 is depressed, even if there is a key 8 being depressed prior to the key operation, the pitch of the key 8 being depressed earlier and the key depressed this time When the pitch difference from the pitch of key 8 exceeds “3”, or key 8 being pressed
When the touch data difference between the touch data of the key 8 and the touch data of the key 8 pressed this time exceeds “9”, the touch data of the key 8 pressed this time is corrected by judging from the tone characteristics. Pronouncing without.

Next, the key-off process of FIG. 4 will be described with reference to the detailed flowchart shown in FIG.

In the key-off process, as shown in FIG. 6, first, the key code of the turned-off key 8 and the off command are output to the tone generator 6 (step Q1), and it is checked whether all the keys 8 are off. (Step Q2). If all the keys 8 are off, the key-on flag is set to "0", and the key-off process ends (step Q3). If all the keys 8 are not off, the key-off process ends.

When the key-on processing and the key-off processing have been completed in this way, as shown in FIG.
Returning to the main processing of FIG. 3, the switch processing (step S
Perform 3).

This switch processing is performed as shown in FIG.
First, the mode changeover switch 5 of the mode changeover switch section 4
Is scanned (step R1), and it is checked whether the mode changeover switch 5 is on (step R2). When the mode changeover switch 5 is off, the mode flag is set to "0" (step R3). When the mode changeover switch 5 is on, the mode flag is set to "1" (step R4), and the switch processing is performed. finish.

When the switch process is completed, the process returns to the main process of FIG. 3, and the keyboard process is sequentially performed in the same manner as described above.

As described above, when the key 8 is depressed and the mode is the correction mode, it is first checked whether or not the key 8 is being depressed. If there is a key 8 being depressed, the pitch difference between the pitch of the key 8 being depressed earlier and the pitch of the key 8 which has been depressed this time is within “3”, and the key is depressed earlier. If the touch data difference between the touch data of the middle key 8 and the touch data of the currently pressed key 8 is within “9”, the touch data of the currently pressed key 8 is pressed first. 8, the pitch difference between the pitch of the key 8 previously pressed and the pitch of the key 8 pressed this time is more than "3", If the touch data difference between the touch data of the key 8 being pressed first and the touch data of the key 8 pressed this time is more than “9”,
Produce sound without correcting touch data.

For example, when a musical note as shown in FIG. 8 is operated by the key 8 and touch data as shown in the lower part of FIG. 8 is obtained, the second musical note (レ) becomes the first musical note (レ). 5), the pitch difference is 1 degree, and the touch data difference is “3” (62−5F = 3), which is within the range of the predetermined values in step P8 and step P10 in FIG. . Therefore, the touch data of the key 8 of the note (d) is corrected to the touch data (5F) of the key 8 of the first note (d), as shown as the corrected touch data in FIG. Similarly, since the pitch difference between the third note (mi) and the second note (d) that is being depressed before that is within a predetermined value, the touch data of the third note (mi) is similarly stored in the second note (mi). The note data is modified to the modified touch data (5F) and the sound is generated. However, the fourth note (fa) is 3
The second note (mi) means that the pitch difference is within a predetermined value,
The difference between the touch data is 25 (5F-44 = 25),
Since it is not within the range of the predetermined value, the sound is generated without correcting the touch data. The pitch difference between the fifth note (S) and the sixth note (S) and between the sixth note (S) and the seventh note (S) is completely 5 degrees, and is within a predetermined range. Sound without modifying touch data. Further, since the pitch difference and the touch data difference between the seventh note (so) and the eighth note (la) are within a predetermined range, the touch data of the eighth note (la) is
Correct the touch data of the third note (S) and pronounce it.

Therefore, when the key 8 is continuously turned on, it is possible to correct the touch data of the key 8 that has been newly turned on based on the touch data of the other key 8 that has been turned on first. Even if there is a variation in the operation speed or the operation intensity of the performance operator, the variation of the touch data due to the variation can be corrected, and even a beginner of the performance can perform the performance without variation in the volume.

Further, when the difference between the touch data of the new key 8 and the touch data of the other keys 8 is within a predetermined range, the touch data of the new key 8 is modified, so that the player If the user intentionally changes the operation speed or operation intensity of the key 8, the touch data can be corrected when there is a variation in the operation of the key 8 without correcting the touch data. Therefore, the touch data can be changed according to the operation of the key 8, and the variation in the operation of the key 8 can be corrected.

Further, the touch data of the new key 8 is corrected only when the difference between the pitch specified by the new key 8 and the pitch specified by the other keys 8 is within a predetermined range .
Since Unishi in that, when a musically pitch changes greatly, that also changes the key operation, depending on the musical flow, it is possible to correct the touch data.

Further, since the mode changeover switch 5 switches between enabling and disabling the touch data correction operation, the variation in the operation of the performance operators can be reduced according to the skill level of the player. It is possible to correct or obtain a change in the touch data according to a delicate operation of the performance operator.

[0051]

According to the present invention, when a performance operator is continuously turned on, the touch data of the newly operated performance operator is replaced with the touch data of the other performance operator that was previously turned on. Since it can be corrected based on touch data,
Even if there is a variation in the operation speed or operation intensity of the performance operator, it is possible to correct the variation of the touch data due to the variation of the performance operator.

Also, the touch data of the new performance operator is corrected only when the difference between the touch data of the new performance operator and the touch data of the other performance operators is within a predetermined range. If the performer intentionally changes the operation speed or operation intensity of the performance operator, the touch data is not corrected, and when the operation of the performance operator varies,
The touch data can be corrected, the touch data can be changed according to the operation of the performance operator, and the variation in the operation of the performance operator can be corrected.

Further, when the difference between the pitch specified by the new performance operator and the pitch specified by another performance operator is within a predetermined range, the touch data by the new performance operator is corrected. Therefore, when the pitch greatly changes, the touch data can be corrected according to a musical flow in which the key operation also changes.

Further, since it is possible to select whether the correction operation of the touch data is valid or invalid, it is possible to correct the variation of the operation of the performance operator depending on the skill level of the player, It is possible to obtain a change in touch data according to a delicate operation of the performance operator.
