Abstract

PURPOSE: To obtain musical tones not possible with natural musical instruments by repetitively instructing sound production and silence during the operation of an operating means to be operated according to operation. CONSTITUTION: Sound production release processing is executed after a revolution SW counter C is reset at the point of the time the counter C=5 is attained when switches (a) to 4c are turned on >=5 times by the continuous operation of an upper turn table 7 by a user. A sound source is attenuated at a steep release rate of the envelope of the musical tone signal during the generation to erase the musical tones when the silence is instructed by such processing. Next, whether key operation is made or not is discriminated at this time and the sound processing is executed at TCO timbre and TNO pitch when there is no key operation. Then, the sound production and the silence are repeated at the timing when the musical tones of the previously assigned timbre and pitch A4 attains the revolution SW counter C=5 when the keyboard is not operated even once after this continuous beat mode is started and only the upper turn table 7 is kept rotated.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound generation control device for controlling sound generation in response to an operation.

[0002]

2. Description of the Related Art Conventionally, an electronic musical instrument having a keyboard is generally known as a device for producing a sound in response to an operation. In this electronic musical instrument, when a key depression occurs, the sounding is instructed in response to this, and when the key releasing occurs, the mute is instructed. Therefore, when the sound source operates in accordance with the sound generation instruction and the mute instruction, musical tones are sequentially generated at timings corresponding to the performance operation.

[0003]

However, in the conventional electronic musical instrument as described above, since the musical tone generation is merely instructed in response to a key depression, like the natural musical instrument such as an acoustic piano or the like, The operation and the generation of musical sound always have a paired relationship. Therefore, while using electronic technology and the like, the pronunciation form in relation to the operation is the same as that of the natural musical instrument, and it is not possible to form an original musical tone generation form.

The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a musical tone control device capable of forming a sounding form which is impossible with a natural musical instrument in relation to operation. It is intended.

[0005]

In order to solve the above problems, according to the present invention, an operating means which operates in accordance with an operation, and a sounding for repeatedly instructing sounding and muting during the operation of the operating means. It comprises a control means or an operating means which operates in accordance with an operation, a tone color designating means for designating a tone color, and a tone color designated by the tone color designating means during operation of the operating means. It has sound generation control means for repeatedly instructing sound generation and mute.
Furthermore, in another configuration of the present invention, an operating means that operates in accordance with an operation, a pitch specifying means that specifies a pitch, and a pitch specifying means that is specified during the operation of the operating means. And a sound generation control means for repeatedly instructing sound generation and mute with a pitch. In addition, an operation unit that operates in accordance with an operation, a tone color designation unit that designates a tone color, a tone pitch designation unit that designates a pitch, and a tone color designated by the tone color designation unit during operation of the operation unit. Therefore, it has sound generation control means for repeatedly instructing sound generation and mute with a pitch designated by the pitch designating means.

[0006]

In the above construction, when the operating means is operated in accordance with the operation, the sounding control means repeatedly gives instructions to sound and mute during the operation of the operating means. Therefore,
By the sounding according to this instruction, sounding is generated repeatedly while the operating means is operating. Further, in the configuration having the tone color designating means, this continuous tapping sound is generated with a designated tone color, and a continuous tone having a tone color which cannot be obtained by a natural musical instrument may be generated. Further, in the configuration having the pitch designating means, the continuous hitting sound is generated at the designated pitch, and the constituent pitches of the continuous tapping sound are changed by designating different pitches. Further, in the structure having the tone color designating means and the pitch designating means, the continuous tone generation occurs with the designated tone color and tone pitch, and moreover, the component pitches of the consecutive tone sounds are specified by designating different tone pitches. Change.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the present invention is applied to an electronic keyboard instrument. As shown in FIG. 1, a keyboard 2, a speaker 3, a switch unit 4, and a turntable device 5 are provided in a musical instrument body 1 of this electronic keyboard instrument. The switch section 4 includes a power switch, a tone color selection switch for selecting a tone color, a switching function from the keyboard playing mode to the continuous tapping mode, and 1-3.
There are provided various function switches such as a continuous hit SW having a function of specifying the continuous hit tone color and a reset SW operated when returning from the continuous hit mode to the keyboard performance mode.

As shown in FIG. 2, the rotary disk device 5 is composed of a disk-shaped lower switch disk 6 and an upper rotary disk 7 having the same diameter. The lower switch board 6 is fixed to the musical instrument body 1, and the upper surface of the lower switch board 6 is located within an area of 90 ° from the center.
The individual switches a, b, and c are arranged on the same circumference. These switches a to c are of a normally open type and are set at equal intervals between the switch a and the switch b and between the switch b and the switch c.

The upper rotary disk 7 is rotatably supported at the center of the lower switch disk 6, and a knob 8 is provided on the upper surface of the upper rotary disk 7 so as to project therefrom. In addition, on the lower surface periphery of the upper turntable 7,
Three protrusions 9 ... Are provided at equal intervals on the same circumference as the switches a to c. Therefore, when the upper turntable 7 is rotated clockwise, the switches are turned on in the order of the switches a → b → c → a as shown in FIG. 3, and the upper turntable 7 is determined by determining the switching order. It can be identified that it is rotating normally (in the case of left rotation, a → c → b
→ a). Further, the rotation speed of the upper turntable 7 can be detected from the time t until the next switch is turned on.
Furthermore, one turn of the upper turntable 7 can be detected by turning on the fourth switch of the same switch, and the time required for one turn of the upper turntable 7 can be detected by the time until the fourth switch of the same switch is turned on.

In addition to the above, the structure of the switch portion includes various types of operators such as a pressure sensitive type, a resistance value detecting type, a micro switch, a sliding switch and the like, in which the switching state is continuously changed according to the operation. Can be used.
Further, in particular, it is not necessary to be a rotary operation type operator having the upper turntable 7, and a slide type operator may be used,
Further, the upper turntable 7 need not be rotatable in both directions, but may be configured to rotate in only one direction.

FIG. 4 is a block diagram showing the overall structure of this electronic musical instrument. The key information generated by the operation of the keyboard 2 and the on / off information from the switch unit 4 and the rotary disk device 5 are fetched by the CPU 14. The CPU 14 operates based on these input information and the program stored in the ROM 10 to control the sound source 11. Sound source 11
Generates a musical tone signal according to the data given from the CPU 14, and the musical tone signal is converted into an analog signal by the D / A converter 12 and given to the speaker 3 via the amplifier 13 and emitted.

As shown in FIG. 5, the ROM 10 stores the tone color data of "piano", "music box", and "wood bass" corresponding to the continuous hitting SWs 1 to 3, as shown in FIG. Further, the CPU 14 is provided with six types of registers (flags) from a continuous hitting mode flag REN to a TNO rank designation counter G as shown in the following table.

[0013]

[Table 1] Next, the operation of this embodiment having the above configuration will be described with reference to the flowchart. That is, when the power is turned on, C
The PU 14 operates according to the flow shown in FIG. 6, executes the initial value setting process (SA1), and sets predetermined initial values in various registers. Subsequently, in the functional SW scan process (SA2), the switch unit 4 is scanned to capture the operation information thereof, and in the rotary SW scan process (SA3), the turntable device 5 is scanned to turn on / off the switches a to c. Capture information. Furthermore, keyboard scan processing (SA
In 4), the keyboard 2 is scanned and the corresponding pitch and duration data of the operated key is fetched based on the scanning result.

Next, continuous tapping sound generation processing (SA5) described later
After that, performance sound generation processing (SA6) is performed. In this tone generation process, in the keyboard performance mode, a musical tone is generated with a pitch and a tone length corresponding to the operation key loaded in SA4. Further, in the flow one round process (SA7), the initialization process at the end of one round is performed, and while the power is on, SA2 is set.
~ SA7 loop is repeated.

The continuous tapping sound generation processing (SA5) is performed according to the flow shown in FIG. That is, it is determined whether or not the continuous hit mode is being set (SB1). If the continuous hit mode flag REN = 0, the continuous hit mode is not being set but the keyboard performance mode is being set. Then, in the keyboard performance mode, the state of the continuous SW is checked (S
B2), if there is no such operation, initialization processing (SB
3) is performed to reset various registers used in the continuous tapping sound generation process, and then the process returns. Therefore, when the keyboard performance mode is set, SB1-S
B3 → Return is repeated.

When the user operates any one of the continuous stroke SWs 1 to 3 to set the continuous stroke mode and the continuous tone color, the process proceeds from SB2 to SB4 to set the continuous stroke mode flag REN. Continuously, the tone color data (see FIG. 5) corresponding to the continuous hit SW is read from the ROM 10,
Set to TCO (SB5). Further, the pitch data of the pitch A4 is set in TNO (SB6), the start flag STF is set (SB7), and then the process returns. Therefore, immediately after the continuous hit mode is set, the pitch data of A4 is set in TNO.

When the continuous tapping sound generation process is performed again after the return, the REN = 1 is already satisfied,
The process proceeds from SB1 to SB8, and it is determined whether or not the rotation SW has been operated, that is, whether or not an ON signal has been input from any of the switches a to c. This switch ac
When no ON signal is input from any of the above, the state of the reset SW is checked (SB17), and when the reset SW is operated, the above-mentioned initialization processing (SB3) is performed, and the operation is performed again. If not,
Return without performing initialization processing. Therefore, after the continuous hit mode is set, SB1 → SB8 → SB17 → return is repeated while the upper turntable 7 is not operated.

After the continuous hitting mode is set, when the user rotates the upper turntable 7 in any direction, any of the switches a to c is turned on. Therefore, the process proceeds from SB8 to SB9, the rotation SW number counter C is incremented, and the state of the start flag STF is detected (SB1
0). This STF is set by SB7 described above, and ST
Since F = 1, the process proceeds from SB10 to SB18, and after resetting this STF, the TCO tone color T
Sound generation processing is performed with a NO pitch (SB16).

That is, when any one of the switches a to c is turned on for the first time after the continuous hit mode is set, any one of "piano", "music box" and "wood base" designated by the operation of the continuous hit SW in advance. The tone generator 11 instructs the sound source 11 to generate a tone having a pitch A4. Then, according to this instruction, the sound source 11 generates a tone signal having the tone color and the pitch A4. This tone signal is sent to the D / A converter 12
And to the speaker 3 through the amplifier 13, and the speaker 3 starts to generate a musical sound of the tone color and the pitch A4. Subsequently, the state of the reset SW is checked (SB17), and if it is not operated, the process directly returns.

If the user continuously operates the upper turntable 7, the process proceeds to SB1➝SB8➝SB9 when the continuous hammering sound generation process is executed next time. At SB9, the rotation SW number counter C is incremented, and it is further checked whether or not the value of the counter C is "5" (SB11). If C <5 is still satisfied, the process proceeds to SB11 → SB17 → RETURN without performing the sound release process of SB13. Therefore, until C = 5, the above S
The tone having the TNO tone and the TNO pitch, which has been sound-produced in B16, continues to be generated from the speaker 3.

Then, when the user continuously operates the upper turntable 7 to turn on the switches a to c five times or more, when the rotation SW number counter C = 5, the SB11 is changed to the SB12. After proceeding to reset the counter C, a sound release process (SB13) is executed. When the mute is instructed by the processing of SB13, the sound source 11 attenuates the envelope of the musical tone signal being generated at a steep release rate, whereby the musical tone that has been generated up to now disappears.

Next, it is determined whether or not the key is operated at this time (SB14), and if there is no key operation, the tone generation processing is performed with the TCO tone color and the TNO pitch similarly to the above (SB16). . Therefore, after starting this continuous hit mode,
When only the upper turntable 7 is continuously rotated without operating the keyboard 2 even once, the tone color is a preset tone and the pitch is A4.
The musical tone is repeatedly generated and muted at the timing when the rotation SW number counter C = 5. Further, at this time, the timing at which the rotation SW number counter C = 5 depends on the rotation speed of the upper turntable 7. Therefore, the musical sound of the designated tone color and the pitch A4 becomes the rotation speed of the upper turntable 7. It will occur repeatedly at a time interval corresponding to the above.

However, if any key is operated on the keyboard 2 while rotating the upper turntable 7, SB14 to S14
Proceeding to B15, the pitch data of the operation key is stored in TNO. Therefore, the TN of the TCO timbre is continued at SB16.
When the tone generation processing is performed at the O pitch, the speaker 3 generates a musical tone having a designated tone color and a tone pitch corresponding to the operation key. Further, when the continuous tapping sound generation process is executed next time, if the key operation is not performed, the process of SB15 is not executed and the storage state of TNO is maintained as it is. Therefore, the same tone color is processed by the process of SB16. Musical sounds of the same pitch continue. Of course, if you operate different keys one after another,
Each time SB15 is executed, the pitch data of TNO is changed, and the processing of SB16 generates a musical sound of the same tone color but a different pitch. At this time, as described above, C = 5
Therefore, the timing of the above is dependent on the rotational operation speed of the upper turntable 7, and therefore the timing of the sound release processing at SB13 and the timing of the sound generation processing at SB16 are also dependent on the rotational operation speed of the upper turntable 7. as a result,
By rotating the upper turntable 7 while adjusting the speed, and pressing the keyboard 2 in response to this, musical tones having arbitrary pitches and tone lengths can be sequentially generated. Therefore, for example, by selecting the "music box" tone color and operating the upper turntable 7 and the keyboard 2, it is possible to perform a melody with the music box tone color.

FIG. 8 shows RO in another embodiment of the present invention.
It shows a part of the data stored in M10. That is, this data is composed of tone color data of "piano", "music box", and "wood bass" corresponding to the above-mentioned 1 to 3 consecutive hitting SWs, and pitch data groups corresponding to these tone color data. Each pitch data group is composed of individual pitch data stored in correspondence with the designated rank values of 1 to 5.

Further, in this embodiment, the continuous hammering sound generation processing (SA5) is performed according to the flow shown in FIG. That is, it is determined whether or not the continuous hit mode is being set (SC1), and if the continuous hit mode flag REN = 0,
The keyboard performance mode is being set, not the continuous tap mode. Then, in the keyboard performance mode, the state of the continuous tap SW is checked (SC2), and if there is no such operation, an initialization process is performed, and various registers used in the continuous tap sound generation process are reset and then the process returns. .
Therefore, when the keyboard performance mode is set, SC1 to SC3 → return are repeated.

When the user operates any one of the continuous stroke SWs 1 to 3 in order to set the continuous stroke mode and the continuous tone color, the routine proceeds from SC2 to SC4 to set the continuous stroke mode flag REN. Subsequently, the tone color data (see FIG. 8) corresponding to the continuous-stroke SW is read from the ROM 10 and T
While setting to CO (SC5), TNO continuous hit S
A pitch data group corresponding to W is set (SC6).
Therefore, for example, if "piano" is selected by the operation of No. 1 continuous hit SW, SC5 and SC6
By this processing, the tone color data of "piano" is set in TCO, and the pitch data "A4""C#4" is set in TNO.
“E5”, “G5”, and “G # 5” are set. Further, the TNO counter G is set to the initial value "1" (SC7), the start flag STF is set (SC8), and then the process returns.

When the continuous tapping sound generation process is performed again after the return, the REN = 1 is already satisfied.
The process proceeds from SC1 to SC9, and it is determined whether or not the rotation SW has been operated, that is, whether or not an ON signal has been input from any of the switches a to c. This switch ac
If there is no ON signal input from any of the above, the state of the reset SW is checked (SC19), and if the reset SW is operated, the above-mentioned initialization processing (SC3) is performed, and the operation is performed again. If not,
Return without performing initialization processing. Therefore, after setting the continuous hit mode, SC1 → SC9 → SC19 → return is repeated while the upper turntable 7 is not operated.

When the user rotates the upper turntable 7 in any direction after setting the continuous hit mode, any of the switches a to c is turned on. Therefore, the routine proceeds from SC9 to SC10, the rotation SW number counter C is incremented, and then the state of the start flag STF is detected (SC11). This STF is set by the above-mentioned SC8 and is in the state of STF = 1.
After proceeding to C20 and resetting this STF, TCO
Sound generation processing is performed at the tone pitch of TNO (G) (SC18).

That is, when any of the switches a to c is turned on for the first time after the continuous hitting mode is set, SC14 in this flow is not executed and G = 1. Therefore, if "piano" is selected as described above, the processing of SC18 instructs the sound source 11 to generate a tone A4 having a tone color of "piano" and G = 1. Then, the sound source 11 generates a musical tone signal having a piano tone color and a pitch A4 according to this instruction. This musical tone signal is given to the speaker 3 via the D / A converter 12 and the amplifier 13, whereby the musical tone of piano tone color and pitch A4 starts to be generated from the speaker 3. Next, check the status of the reset switch (S
C19), if not operated, the process directly returns.

If the user is continuously operating the upper turntable 7, the process proceeds to SC1.fwdarw.SC9.fwdarw.SC10 when the continuous hammering sound generation process is executed next time. At this SC10, the rotation SW number counter C is incremented, and further,
It is checked whether or not the value of the counter C is "5" (SC12). If C <5 still, SC17
SC11 → SC1 without performing the pronunciation release process
Go to 9 → return. Therefore, until C = 5, the musical tone having the pitch A4, which is the piano tone color generated in the above-described SC18, is continuously generated from the speaker 3.

When the user continuously operates the upper turntable 7 to turn on the switches a to c five times or more, when the rotation SW number counter C = 5, SC12 is changed to SC13. Then, the counter C is reset. Further, the TNO rank designation counter G is incremented (SC14), and it is determined whether or not the incremented counter G becomes "6" (SC1).
5). If G <6, the process proceeds to SC17 without performing the process of SC16 and performs the sound release process. When mute is instructed by this sound release processing, the sound source 11
Reduces the envelope of the musical tone signal being generated with a steep release rate, whereby the musical tone that has been sounding until now disappears.

After the release of the tone generation, the tone generation process is performed in the SC18 at the TCO (T) tone pitch of the TCO tone color in the same manner as described above. Therefore, assuming that G = 2 at present, in the case of this example, the tone generator 11 is instructed to generate a musical tone having a tone color of "piano" and a pitch C # 4. Then, the sound source 11 generates a musical tone signal having a piano tone color and a pitch C # 4 according to this instruction. This musical tone signal is applied to the speaker 3 via the D / A converter 12 and the amplifier 13, whereby the musical tone of piano tone color and pitch C # 4 starts to be generated from the speaker 3. Then, check the state of the reset SW (SC19), and if it is not operated,
Return as it is.

If G = 6, the process proceeds from SC15 to SC16 to set the TNO rank designating counter G to the initial value "1", and then the tone release process (AC17).
And TCO (T) tone color TNO (G) pitch generation processing (SC1
Perform 8). That is, the TNO rank designation counter G is 1
Repeatedly changing between 5 and 5, the pitch data to be read out is sequentially designated by the value, and the tone generation processing of SC18 is performed at the pitch designated by the value of the counter G. At this time, the timing when C = 5 is the upper turntable 7
Therefore, the timing of sound generation release processing in SC17 and the timing of sound generation processing in SC18 also depend on the rotation operation speed of the upper turntable 7.

Therefore, by performing the rotation operation while adjusting the speed of the upper turntable 7, it is possible to play a musical piece having an arbitrary pitch in the order of the pitches forming the pitch data group. Therefore, for example, if the pitch data of the pitch data group is composed of pitches corresponding to a predetermined piece of music and this piece of music is known to the user in advance, the user can change only the pitch length by operating the upper turntable 7. It is possible to perform a semi-automatic performance, that is, a special performance in which only the note length of the music is played. Also, if the wood-based pitch data group is composed of pitch data of the accompaniment sound of a certain piece of music, a semi-automatic accompaniment performance is also possible.

In the embodiment, the structure in which the continuous tapping sound is simply generated according to the rotation of the upper turntable 7 is shown.
Further, according to the rotation state of the upper turntable 7, effect addition parameters such as tremolo depth and vibrato depth are controlled stepwise, and the pitch data group used is changed according to the rotation direction. May be.

Further, the pitch pattern forming the pitch data group may be set by the user, and the tone color is not limited to the musical instrument tone color, and may be a sampling effect sound such as a cry of an animal. Further, in the embodiment, the configuration applied to the keyboard instrument is shown, but it may be configured as a single unit as the sound generation control device, or may be applied to another instrument such as a guitar. In addition, in the embodiment, the previous pronunciation is released before the next pronunciation processing, but the timing of the release processing is not limited to this, and the release processing may be performed at the timing when a plurality of pronunciations coexist. You may

As described above, according to the present invention, the sounding and muting are repeatedly instructed during the operation of the operating means which is operated in response to the operation. It is possible to form a musical tone generation pattern that is impossible with a natural musical instrument in which an operation and a musical tone always have a paired relationship, and it is possible to expand the musical performance expression.

By repeating sounding and muting with a specified tone color, it is possible to generate a continuous striking sound of a tone color that is not possible with a natural musical instrument. Melody elements can be added to sounds. Furthermore, since the operating means has a structure that has a turntable that rotates in response to the operation, a smooth continuous operation is possible and continuous tapping sound can be generated. In addition, by instructing to sound and mute at time intervals according to the operating state of the operating means, it is possible to freely change the tempo of the repeated tapping sound by manual operation. By instructing the mute corresponding to the preceding sounding instruction, it is possible to clearly generate each continuous tap sound.

By instructing sounding and muffling at time intervals that become shorter as the operating speed becomes faster, it is possible to generate continuous hammering sounds at a timing that matches the feeling of operation. Further, by designating the pitch based on the pitch data stored in a predetermined order in advance, it is possible to generate the continuous hammering sound with the pitch according to the predetermined pattern. In addition, pitch data is stored in a predetermined order for each tone color, and pitches are generated based on the pitch data corresponding to the designated tone color, so that musical tones having a pitch according to the pattern are generated with the designated tone color. Therefore, it is possible to diversify the sound of repeated hits.
