Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone controller for controlling a tone signal comprising an electric signal to add a sound effect to the tone signal.

[0002]

2. Description of the Related Art In the field of electric musical instruments or electronic musical instruments, there has conventionally been an effector as a device for controlling a tone signal composed of an electric signal to obtain various sound effects. For example, a volume control device, a tone color control device, an echo addition device, a tremolo addition device, a vibrato addition device, and the like are mixedly mounted on the effector, and a device for freely adding an acoustic effect using these devices is devised. In addition to the effector, for example, a sound signal may be added to a musical sound signal by adding a control signal to a sound source or a mixer that generates a musical instrument sound by an electronic circuit.

FIG. 24 is a conceptual diagram of a configuration for controlling an effector. In the figure, reference numeral 10 denotes an effector, 11 denotes a signal source of an electronic musical instrument or an electric musical instrument or a CD player, a tape recorder, a record player, or the like for giving a tone signal to the effector 10, and 12 denotes a tone signal to which a sound effect is added by the effector 10. Reference numeral 13 denotes a musical tone controller which supplies a control signal to the effector 10.

Various types of musical tone controllers 13 have been proposed. One of them is a joystick type.
With a joystick type, two rotary potentiometers are operated by one joystick, two-axis position signals are transmitted, and the two-axis position signals are input to the effector 10 to control, for example, volume and tone. Alternatively, it is a controller of a type in which a joystick is finely shaken to apply tremolo or vibrato. Other mechanical controllers include a wheel type or a fader type using a slide volume.

As a recent tendency, there are many cases where a flat position sensor is used for the tone controller 13. A planar position sensor is also called a touch panel sensor or the like. When a pressing force is applied to any position of a sheet-like planar body, it corresponds to the position of the pressed point (generally, a biaxial position of X and Y). Generate electrical signals. By inputting the two-axis position signal to the effector 10, a configuration for performing volume control, tone control, addition of vibrato, addition of tremolo, and the like has been considered.

[0006]

Conventionally, there has been seen an example in which a planar position sensor having a planar shape is used for the tone controller 13, but the operation method is complicated and not always easy to use. For example, when performing volume control, when the fingertip is slid in the positive direction of the X-axis on the plane of the flat position sensor, the volume is increased in the positive direction, and then the volume is returned to the original volume. To return to, the fingertip must be returned to the original position again. If this operation must be repeated many times, it will be a difficult task.

That is, if the volume of the first beat of each bar is set to be high and the volume of other sounds is set to be low in accordance with the tempo of the music, the fingertip is continuously reciprocated on the X axis during the progress of the music. This is a huge task.
Also, when giving a sound effect that repeatedly returns to the original volume at a predetermined slow speed, for example, after increasing the volume, the fingertip is returned to the original position at the same slow speed every time. The returning operation must be continued, which is not only difficult, but also has poor reproducibility.

An object of the present invention is to propose a tone controller which improves the operability of a tone controller using a plane position sensor and which can be performed with a simple operation even when the same operation is repeatedly performed.

[0009]

According to the present invention, in a musical tone controller using a plane position sensor, a signal converter for converting a position signal output from the plane position sensor into a control signal to be supplied to a controlled device and outputting the control signal. A touch-off detecting means for detecting that the input operation on the plane position sensor has been released, and an arbitrary position of the plane position sensor,
The present invention is characterized in that the touch-off detecting means comprises a return point storing means for storing a return point for restoring the state of the controlled device every time the touch-off is detected.

According to the structure of the present invention, the state of the controlled device automatically returns to the original state by pressing and releasing an arbitrary position of the plane position sensor. Therefore, it is not necessary to reciprocate the fingertip on the plane position sensor. Absent. Therefore, a tone controller with good operability can be provided. According to the present invention, in addition to the basic structure proposed in claim 1, each time the touch-off detecting means detects a touch-off, a release position storing means for storing an operation position at the time of the touch-off, and a release position stored in the release position storing means And a movement calculating means for sequentially calculating and outputting the position from the release position side to the return point stored in the return point storage means from the release position side. .

According to this structure, when the touch-off detecting means detects the touch-off, the movement calculating means is started, and the position from the release position to the return point is calculated at a predetermined interval.
Since the calculated position is output to the controlled device, the controlled device is returned to the control state corresponding to the return point when a predetermined time has elapsed after the touch-off, and the volume can be smoothly changed.

Therefore, for example, in the case of volume control, for example, when the sound of the first beat of a song is strongly output, and the subsequent sounds are repeatedly output at a certain reduced volume,
At the time of the sound of the first beat, a pressing force is applied to a position where the volume of the plane position sensor is controlled to be loud, and then, when the pressing force is released, the controlled device is controlled to the return point stored in the return point storing means, and automatically. The volume is reduced, and the sound after the other first beat is reduced. To repeat this, it is only necessary to press the position where the volume is increased at the timing when the sound of the first beat is output, and it is only necessary to repeat this pressing operation.

Therefore, according to the present invention, it is possible to provide an easy-to-use tone controller with improved operability.

[0014]

FIG. 1 shows the basic configuration of a tone controller according to the present invention. In FIG. 1, reference numeral 20 denotes a tone controller according to the present invention. The tone controller 20 according to the present invention comprises a plane position sensor 21 and a return point storage means 23- constructed inside a microcomputer MPU.
1, the signal converter 24-1 and the touch-off detecting means 24
-2.

In the example shown in FIG. 1, the planar position sensor 21 uses a ribbon-shaped planar position sensor. Therefore, in this case, the position signal SX in the one axis direction X is output. That is, by moving the position of the pressing point P in the X-axis direction, a DC voltage corresponding to the position of the pressing point P is output. In the example shown in FIG. 1, when the pressing point P is moved to the left end Xo, the voltage of the position signal SX becomes 0 V, and when the pressing point P is moved to the right end Xn, the position signal SX outputs the maximum value NV. Therefore, the position of the pressing point P can be known from the voltage between 0 and NV.

The position signal SX is input to an AD converter 27, converted into a digital signal by the AD converter 27, and input to the microcomputer MPU. As is well known, the microcomputer MPU includes a central processing unit 22 and a rewritable memory RAM 23.
, Read-only memory ROM 24 and input port 2
5, the output port 26 and the like.

An AD converter 27 and a panel switch group 28 are connected to the input port 25, and a position signal SX and an operation signal input from the panel switch group 28 are input through the input port 25. Various setting values input from the panel switch group 28 are displayed on the display 29. The central processing unit 22 transfers the position signal input through the input port 25 to the signal converter 24-1.
At -1, the position signal is converted into a signal for controlling the effector 10. That is, if the effector 10 to be controlled is a device that operates according to the MIDI standard, for example, the position signal is converted into a MIDI standard signal, and the MIDI standard signal is supplied to the effector 10 through the output port 26 and the connector 31. The effector 10 is controlled. As another form of the signal to be converted, RS-232C or the like can be considered.

In the embodiment shown in FIG. 1, the signal converter 24-1 is used.
And the touch-off detecting means 24-2 in the read-only memory R
The case where it is configured by the program written in the OM 24 is shown. Also, a case is shown in which the return point storage means 23-1 is configured using a partial storage area of the rewritable memory RAM 23. The touch-off detecting means 24-2 outputs the position signal SX
Can be constituted by, for example, a program that performs a differential operation. In other words, when the pressing point P of the planar position sensor 21 is released, the input position SX sharply returns to the zero potential at the point Xo. A signal can be obtained. Touch-off can be detected from this differential signal.

The return point storage means 23-1 has a touch-off detection
After the output unit 24-2 detects the touch-off, the controlled device
In this example, the return of the state of the effector 10 is performed.
Set the return point. For example, the panel
A switch for setting a return point is provided in the
Press the position to be set as the return point of the position sensor 21 and
No.SX₁And set the return point setting switch in this state.
Operation (input a signal that turns on instantly)
Signal SX transmitted from the position sensor 21 ₁Return
By storing the return point in the point storage means 23-1,
Can be set. Therefore, the return point storage means 23-
Set an arbitrary position of the plane position sensor 21 in 1
Can be.

Assuming that the tone controller 20 controls the fader function 10A (volume control function) of the effector 10, the plane position sensor 21 shown in FIG.
Function 10 so that the volume is maximized at the right end Xn of the
A is controlled, and a position X substantially at the center of the planar position sensor 21 is controlled.
Assuming that ₁ is set as the return point, when the finger is touched and released at the right end Xn, the volume changes from the intermediate value to the maximum value and from the maximum value to the intermediate value by a simple operation of touching and releasing the finger. Can be given. In addition, the volume can be changed by simply changing the touch position.

For example, when the drum pattern as shown in FIG. 3A is input to the effector 10 and the sound is emitted from the loudspeaker, the plane position sensor 2 is output at the timing shown in FIG. 3B.
By touching the right end of 1, the volume can be increased at the position of the bass drum to add an accent. In addition, by changing the touch position when adding an accent, it is possible to change the manner in which the accent is applied, or to turn off the bass drum sound. Further, the setting position of the return point X ₁ is set to the left end Xo plane position sensor 21 can be carried out an operation such as gate, for example, it is possible to output only the sound of the bass drum. In this way, the effector 10
Input a continuous sound to the flat position sensor 2 according to the rhythm.
By hitting 1, a sound without a rhythm can be converted to a sound with a rhythm.

FIG. 4 shows an embodiment in which a release position storage means 23-2 and a movement calculation means 24-3 are added to the configuration shown in FIG. In other words, the position volume change is touching the plane position sensor 21 in the embodiment shown in FIG. 1, but was not given only at two points of the return point X _1, the position touched with a finger in the embodiment shown in FIG. 4 the release position upon detection is stored in the released position storage unit 23-2 a touch-off when returning to return point X ₁ from the calculated a plurality of position signals to return point from the release position by moving calculation means 24-3 Then, a case is shown in which the calculated position signals are sequentially output to the effector 10 to gradually change the state of the effector 10 from the release position to the return point.

Therefore, if the configuration of this embodiment is used for volume control, for example, when returning from the maximum volume to the return point,
As shown in FIG. 5C, the sound attenuation can have a time constant, and the change in volume can be expressed smoothly. still,
The movement calculation means 24-3 shown in FIG. 4 can be constituted by a calculation function of a microcomputer. However, as another method, the movement calculation means 24-3 is previously stored in, for example, the read-only memory 24 from the left end Xo to the right end Xn of the plane position sensor 21. The position information may be stored as a table, the release position and the return point may be specified from the table, and the position information between them may be read. Also, when reading out the position information, the volume can be discretely changed by reading out the address step by step.

FIG. 6 shows a configuration in which a return speed setting storage means 23-3 and a return speed control means 24-4 are added to the configuration shown in FIG. By adding these configurations, it is possible to freely set the speed to return from the release position to the return point X ₁ (time constant). As a result, the high-speed change of only the volume change shown in FIG. 1 is reciprocated between two points, is relatively long time to return to return point X ₁ from the release position, the control returns to the return point in the slow changes Can be done.

FIG. 7 shows still another embodiment of the present invention.
In this embodiment, an embodiment is shown in which a configuration for controlling the functions of a plurality of channels of a controlled device by one planar position sensor 21 is added. In this embodiment, a case will be described in which a function for performing a function of performing different volume control for each part of an instrument is added. This function is generally called a crossfade function.

In the embodiment shown in FIG.
With the channel tone signals MU1 and MU2 being input, the two-channel fader 10A mounted on the effector 10 by a position signal that outputs the tone signals MU1 and MU2 of this channel from the same planar position sensor 21.
And 10B are differentially controlled with each other.

To this end, the tone controller 20 has two signal converters 24-1A and 24-2 for sending control signals to the faders 10A and 10B of the channel of the effector 10.
1B, and these two signal converters 24-1A and 24-
1B, the position signal S sent from the plane position sensor 21
X is converted into a two-channel signal that changes differentially with each other, and is sent to the effector 10. Therefore, the effector 10
8, in the path of the fader 10A, the left end Xo of the planar position sensor 21 has, for example, the maximum volume and the right end Xn
Becomes zero volume. In the path of the fader 10B, the control is such that the left end Xo of the plane position sensor 21 has zero volume and the right end Xn has the maximum volume.

The restoring point storage means 23-1, the release position storage means 23-2, the touch-off detection means 24-2, and the movement calculation means 24-3 have the same structure as in the embodiment of FIG. Can be shared. According to the configuration of FIG. 7 to set the position of the left end Xo plane position sensor 21 in the return point X _1, it touches the position of the right end Xn, while fingering the music signal MU1 is volume zero, the tone The signal MU2 has the maximum volume. When the finger is released from the plane position sensor 21,
This time, the tone signal MU1 has the maximum volume and the tone signal MU
2 has zero volume.

For this purpose, for example, as shown in FIG. 9A, a performance of a half note of note name "G" is input as a tone signal MU1, and a performance of a half note of note name "A" is input as a tone signal MU2. 9B, the right end Xn of the plane position sensor 21 is set to the timing shown in FIG. 9B (ON).
If touched with (−OFF), sound can be emitted from the loudspeaker 12 with a phrase as shown in FIG. 9C.

Therefore, an effect that a monotonous tone can be converted into a complex tone and played by a simple operation of repeating pressing and releasing one place is obtained. Music MU
Even when two types of drum patterns are input to 1 and MU2, these can be combined to create different drum patterns. FIG. 10 shows an example. FIG. 10A
FIG. 10B shows a drum pattern 1 and a drum pattern 2 which are different from each other. These drum pattern 1 and drum pattern 2 are input to the effector 10 as musical tone signals MU1 and MU2. At the same time, by touching the right end of the planar position sensor 21 at the timing shown in FIG. 10C, the loudspeaker 12 can generate the composite pattern shown in FIG. 10D.

FIG. 11 shows an embodiment in which a return speed setting means 23-3 and a return speed control means 24-4 are added to the configuration of FIG. By setting the return speed to a slow speed by adding these configurations, it is possible to obtain an effect that a very slow crossfade can be automatically performed. FIG. 12 shows another application example of the tone controller shown in FIGS. In the embodiment shown in FIG. 7 and FIG.
In addition, a control signal of two channels may be used to control a fader 10A for controlling the volume built into the effector 10, and another control system 10C such as a tone color controller or a pitch bend. For this purpose, the signal converter 24
An address code or channel number for specifying a controlled device to be added to the control signals output from -1A and 24-1B may be specified for the volume controller and the tone controller.

FIG. 13 shows an embodiment in which the tone controller 20 outputs a control signal of three channels.
That is, in this embodiment, a two-channel control signal for executing the cross-fader control is output according to the operation signal of the plane position sensor 21, and the pressure-sensitive sensor 32 is arranged below or above the plane position sensor 21, Pressure sensor 3
2 shows a configuration in which a pressing force is detected by the control signal 2 and a control signal of one channel is output by the pressing force.

Therefore, in this embodiment, the plane position sensor 21
A / D converters 27A and 27B are provided for both the pressure sensor 32 and the pressure sensor 32. The digital position signal and the pressure detection signal, which are A / D converted by the A / D converters 27A and 27B, are taken into the central processing unit 22, and these input signals are input. May be converted into control signals for respective destinations by the signal converters 24-1A, 24-1B, 24-1C and sent to the effector 10.

In this case, the return point storage means 23-1, the release position storage means 23-2, and the return speed setting storage means 23-
3. Touch-off detection means 24-2, movement calculation means 24-
3. It is necessary to provide the return speed control means 24-4 for the plane position sensor 21 and the pressure-sensitive sensor 32 in pairs. In the effector 10, in this example, two-channel faders 10A and 10B differentially execute cross-fade control by a control signal transmitted from the planar position sensor 21, and further mix the two channels of the cross-fade-controlled tone. After that, if the volume is controlled by the control signal transmitted from the pressure-sensitive sensor 32 by the common fader 10C, both the musical tones MU1 and MU2 can be commonly controlled by the pressing force. The control signal transmitted from the pressure sensor 32 is set such that the more the pressure is applied to the pressure sensor 32, the more the gain of the fader 10C is increased and the volume is increased.

According to the configuration shown in FIG. 13, when the finger is not touching the planar position sensor 21, the effector 10
MU1 and MU2 are input to fader 10C
Are not output because the gain of the is narrowed. When a finger touches the planar position sensor 21 and a pressing force is also applied to the pressure sensor 32, a musical sound is emitted from the loudspeaker 12 at a volume corresponding to the pressure. When the pressing force is released, the volume is reduced by the control of the return speed control means 24-4A and 24-4B according to the speed set in the return speed setting storage means 23-3A, 23-3B, and finally the fader 10C is turned off. The volume is reduced to zero.

FIG. 14 shows another embodiment of the present invention. In this embodiment, a case is shown in which a planar position sensor 21 'for detecting positions in two axial directions of an X direction and a Y direction is used. The detection signals SX in the X-axis direction and the detection signals XY in the Y-axis direction are AD-converted by AD converters 27A and 27B, respectively, and are taken into the microcomputer MPU. Inside the microcomputer MPU, the position detection signal SX in the X-axis direction and the position detection signal SX in the Y-axis direction are
Signal converters 24-1A and 24-2 for converting the
By simply providing -1B as a pair, other means can use the signal from the same sensor and share it.

In this embodiment, the effector 1 is controlled by position detection signals SX and SY of two channels in the X-axis direction and the Y-axis direction.
The case where the fader 10A and the pitch shifter 10D mounted on the “0” are controlled is shown. That is, the position detection signal SX in the X-axis direction
Controls the fader 10A. Further, the pitch shifter 10D is controlled by the position detection signal SY in the Y-axis direction. As shown in FIG. 15, the signal converter 24-1A converts the control signal into a control signal for the effector 10 so that the volume becomes maximum on the right end Xn side of the X-axis and the volume becomes zero on the left end Xo.
The pitch shift of the pitch shifter 10D at the central position Y ₁ of the Y-axis direction is higher pitch the closer to the upper end Yn in the Y-axis direction at zero, so that the pitch becomes lower the closer to the lower end Yo, signal converter 24-1B Converts into a control signal of the effector 10.

In this embodiment, the movement calculating means 24-3 connects a release point and a return point at which the touch-off detection means 24-2 detects the touch-off with a straight line, and sequentially calculates the position on the straight line from the release point side. It can be configured by a program. Therefore, the return point is set to XY ₁ as shown in FIGS. 14 and 15, the position touched with the rhythm X
When selected as Y _2, the volume of the musical tone that is entered at that time for each touch position XY ₂ becomes large, which together with the pitch of the sound is shifted to the higher. Planar position sensor 21 '
When the finger is released, the sound gradually and linearly decreases in accordance with the return speed stored in the return speed setting storage means 23-3, the pitch shift amount changes in the direction of zero, and finally the volume becomes zero. Become. When changing the position XY ₂ touching the change in volume, the pitch shift amount of the sound is changed.

[0039] with the rhythm in a state where for example the drum pattern as shown in FIG. 16A are input position XY ₂
When touched, the bass drum sound is emphasized by the volume,
In addition, since the sound is swept to a higher pitch, the sound is further emphasized. According to the musical tone controller 20 using the planar position sensor 21 'for detecting positions in two directions of the X-axis direction and the Y-axis direction, not only the usage form shown in FIG. 14 but also, for example, as shown in FIG. Axial pitch shifter 10D
To control the filter 10E in the Y-axis direction.

As a control form of the pitch shifter 10D, for example, as shown in FIG. 18, the pitch shift amount of the pitch shifter 10D is set to zero at the center position in the X-axis direction, the pitch shifts to the maximum value at the right end Xn, and the pitch shifts to the maximum value at the left end Xo. The conversion characteristics of the signal converter 24-1A can be set so as to shift to the lowest value. Further, the conversion characteristic of the signal converter 24-2 can be set such that the filter 10E cutoff frequency becomes the lowest frequency at the lower end Yo in the Y-axis direction and becomes the highest frequency at the upper end.

In the embodiment shown in FIGS. 14 and 17, the return point storage means 23-1 is provided as a pair so that the return points of the position signals SX and SY in the X-axis direction and the Y-axis direction are different. Can be set to the position. FIG. 14 and FIG.
7 can be used in addition to the usage method of the tone controller 20 shown in FIG. 7, but since the present invention has the gist of the configuration of the tone controller 20, further description of the usage method is omitted. I do.

FIG. 19 shows another embodiment of the tone controller 20 according to the present invention. This embodiment proposes a configuration in which the return route storage means 23-4 is provided in the embodiment shown in FIG. That is, the embodiment of FIG. 14 shows a case where the path returning from the release point to the return point is determined as the shortest straight line, and each position on the straight line is calculated by the movement calculating unit 24-3. This embodiment proposes a configuration in which a route from a release point to a return point can be freely set.

FIG. 20 shows various routes. FIG.
The path A shown in FIG. In addition to the straight line, curve B,

While the return path setting switch is being turned on or off in step 8, if the finger traces between the release point XY ₂ and the return point XY ₁ , the position data on the traced line is returned to the return path storage means. 23-4.

When the return path setting switch is set to the ON or OFF state and the surface of the flat position sensor 21 is traced in this state, the previously stored position data indicating the return path is erased and a new one is returned. The input return path is stored.
When the return path storage means 23-4 is provided, the movement calculation means 24-3 may not be provided. Return path storage means 2
The provided by storing the return path of any form this return route storage unit 23-4 3-4 speed gradually from the middle, for example start a change in volume when returned to the return point XY ₁ after the touch-off It is possible to obtain a return path that makes various changes, such as changing the speed, changing the speed in the reverse direction, or changing the pitch shift gradually and gradually from the middle.

FIG. 21 shows still another embodiment of the present invention. In the embodiment shown in FIG. 21, the planar position sensor is 21A '.
And 21B ', one of which is a planar position sensor 21A'.
To transmit a position signal for controlling the effector 10,
A case is shown in which the return point is changed by the other planar position sensor 21B '. In this case, the A / D converters 27A and 27B perform time division on the X-axis and Y-axis position detection signals of the planar position sensors 21A 'and 21B', respectively.
A case is shown in which D-conversion is performed, and AD conversion is performed on signals of four channels by two AD converters 27A and 27B.

[0046] That is, when setting the return point XY ₁ in plane position sensor 21A' as shown in FIG. 22, to change the return point XY ₁ In the plane position sensor 21B' only restored as shown in FIG. 23 The position where you want to change the point, eg XY '
