BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gesture-type musical sound control apparatus for controlling musical sounds by gestures of a player's arms and hands.

[0002]

2. Description of the Related Art One of the objects of a gesture-type electronic musical instrument in which a performance is conventionally performed by a gesture is to improve the expressive power and to visually recognize a part of the performance. Accordingly, an example of a gesture-type musical tone control device (see Japanese Patent Application Laid-Open No. 6-202635) will be described with reference to FIGS. 6 to 8. In this musical tone control device, a musical tone is controlled by a grip operator and a finger operator. Is controlled. FIG. 6 is a front view showing the appearance of the grip controller in the gesture-type musical sound control device. Reference numeral 200 denotes a left grip controller that is gripped and operated by the left hand, and 300 is a right grip controller that is gripped and operated by the right hand. These grip controllers 2
Each of 00 and 300 has two key rows a and b each composed of four grip keys.

[0003] Among the key rows, the key row a is located on the side closer to the base of the finger when the grip controllers 200 and 300 are gripped, and is a natural key. Also, the key row b is the grip controller 200, 3
When 00 is gripped, it is positioned far from the base of the finger and is a sharp (#) key. The key row A in row A is a key row indicating an octave lower octave (octave from C2), the key row B in row B is a key row indicating an octave in C3, and the key row in row C is C is a key sequence that indicates a range one octave higher (octave from C4), and a key sequence D in row D is a key sequence that indicates a range two octaves higher (octave from C5).

As shown in FIG. 7A, the gesture-type musical sound control device includes an elbow controller 124-1 mounted on an elbow and a wrist controller 124-2 mounted on a wrist. The note name (pronunciation note) is determined by the left and right elbow controllers. The volume and pitch bend amount are controlled by the list controller. FIG.
(A) shows an elbow controller 12 attached to the right arm.
4-1 and the wrist controller 124-2 are shown, and the elbow controller and the wrist controller mounted on the left arm are omitted.

[0005] The elbow controller and the wrist controller are provided with an elbow sensor or a wrist sensor composed of a strain sensor whose resistance changes when the elbow or the wrist is bent. The bending condition of the elbow or the bending of the wrist is provided by these sensors. The condition has been detected. FIG. 7B shows a detection range of the elbow bending angle. The detection range is as follows. The range where "1" is detected is shown from the state where the elbow is extended to the state where the elbow is not bent much, and the range where "2" is detected is the state where the elbow is bent from the state where the elbow is not bent much to the middle, The range detected as "3" is from the state where the elbow is bent to the middle position to the state where the elbow is bent deeply.

[0006] Based on the combination of state 1, state 2, and state 3 detected by the left and right elbow controllers, C, D, E, F as shown in the table of FIG.
.., B's note name (pronunciation note) has been determined. Since the tone control device is configured as described above, the elbow controller and the wrist controller are mounted on the left arm and the right arm, and the grip controller is held on the left and right hands. Then, the user selects a pitch name by bending the left arm and the right arm at a predetermined angle, and operates a predetermined grip key of the grip controller gripped at the sound generation timing, whereby the predetermined selected pitch name is generated in a predetermined octave. Become so. In this case, for example, if C is selected as the pitch name and the grip key on the b-th row and the B-th row of the grip controller is operated, the tone is generated at the pitch of C3 #.

Next, FIG. 8 shows a block diagram of the tone control device. A controller 114 composed of an elbow controller and a wrist controller mounted on the left arm is connected to an input interface (I / I /
F) Input via 113. The left grip controller 200 includes a microprocessor (CPU) 11
0, the CPU 110 converts the operation amount from the elbow controller and the wrist controller into a digital signal, fetches the operation data of the 4 × 2 grip keys provided on the grip controller 200, and outputs the serial I / O signal. Belt control unit 100 via F109
Has been sent to. The control program stored in the ROM 112 is also used for the serial I / F 109 during the initial processing.
Is transmitted to the belt control unit 100 via the.

The belt controller 100 can be mounted on a player's belt, and has a main CPU 1 inside.
01, and the main CPU 101 operates based on the sent control program. Then, a tone control signal is sent to the tone synthesizing device 107 so that the tone synthesizing device 107 synthesizes a tone signal corresponding to the pitch, volume, pitch bend, and the like indicated by the transmitted data. The tone synthesized by the tone synthesizer 107 is generated by the sound system 108.
The configuration of the right grip controller 300 is the same as that of the left grip controller 200, and its operation is the same.

[0009]

In the above-mentioned conventional tone control device, the octave of the note name to be pronounced is selected by the grip controller shown in FIG. To choose. However, since these selections are made by the grip keys arranged in 4 rows and 2 columns, there is no problem in operating the natural key, but the sharp key in the b column located far from the base of the finger is operated. In such a case, there is a problem that the natural key in row a located on the inner side is often operated at the same time, resulting in erroneous sound generation. SUMMARY OF THE INVENTION It is an object of the present invention to provide a musical tone control device that does not generate erroneous sound even when an erroneous key operation is performed on a grip controller.

Since the generation of the musical tone corresponding to the first key is suppressed, erroneous sound generation can be prevented, and the playability can be improved.

[0012]

FIG. 1 is a block diagram showing the configuration of an embodiment of a tone control apparatus according to the present invention. In this figure, the CPU
(Central processing unit) 1 is connected to a bus line 16, and is stored in a ROM (Read Only Memory) 2.
Each unit is controlled based on the PU program. At the time of performance, the CPU 1 sends the grip keys of the grip controllers 12 and 14 to the sound source 6 via the bus line 16.
The tone generator 6 generates a tone signal by transmitting a tone control signal such as key-on / key-off data or tone color data by detecting an operation amount from the elbow controllers 8 and 10. The tone signal is supplied to the transmitter 7 so that the signal transmitted from the transmitter 7 is received and sounded by a sound system (not shown). Further, the tone signal generated at this time is determined by a preset tone selected from a plurality of tone stored in the ROM 2 or RAM (Ra).
The sound is generated by a tone or the like stored by the user in the ndom access memory 3.

Each of the switches 5 is connected to a bus line 16 so that the user can set tone parameters and switch functions of the grip controllers 12 and 14 while observing the display screen of the display 4. The elbow L controller 10 for the left arm is connected to an analog-to-digital converter (ADC) L11, the operation amount of which is converted into digital data and transmitted to the bus 16, and the elbow R controller 8 for the right arm is also analog. A digital converter (ADC) R 9 is connected, and the operation amount is converted into digital data and transmitted to the bus 16.

Further, the grip R controller 12 gripped by the right hand is connected to the bus 16 via a detector R13, and the detectors R13 are arranged in four rows and two columns provided in the grip R controller 12. It detects which of the eight grip keys has been operated and sends the detected data to the bus 16. Further, the grip L controller 14 gripped by the left hand includes the detector L 1
5 is connected to the bus 16 but the detector L 1
5 is a 4 provided in the grip L controller 14
It detects which of the eight grip keys arranged in the row 2 column has been operated, and sends out the detected data to the bus 16. The data sent to these buses 16 is C
The data is taken in by the PU 1 and used as data for various tone control signals.

As shown in FIG. 7A, the elbow R controller 8 and the elbow L controller 10 are mounted on the elbows (elbows) of the right arm and the left arm.
Is provided with a strain sensor, and since the resistance value of the strain sensor changes according to the bending angle of the elbow, the operation amount of the elbow controllers 8, 10 is output as a change in the resistance value. Further, as shown in FIG. 7B, the bending angle of the elbow is detected in three detection ranges. This detection range is the following three types as in the conventional case. That is, the range where "1" is detected in the figure is a state where the elbow is extended to a state where the elbow is not bent much, and the range where "2" is detected is a state where the elbow is not bent much and the state where the elbow is bent from the middle. , "3" is detected from a state in which the elbow is bent moderately to a state in which the elbow is bent deeply.

The combination of state 1, state 2, and state 3 detected by the left and right elbow controllers causes C, D, E, F,... As shown in FIG.
・ The note name (pronunciation note) of B is determined. For example,
If the elbow L controller 10 is bent deeply to state 3, and the elbow R controller 8 is bent shallowly (or not to be bent) to state 1, the note name G is selected.

The grip R controller 12 and the grip L controller 14 are provided with eight grip keys 0, 1, 2,..., 8 arranged in four rows and two columns. FIG. 4 shows an example of the key assignment of the grip key. Grip keys 0, 2,
The key row a composed of 4 and 6 is the grip controller 1
When the user grips 2, 14, the finger is located closer to the base of the finger and is regarded as a natural key. The key row b is composed of grip keys 1, 3, 5, and 7, and is located farther from the base of the finger when gripping the grip controllers 12, 14, and is a sharp (#) key. This is because the sharp key is used less frequently, so it is located farther away.

A row A of key rows A composed of grip keys 6 and 7 is a key row indicating an octave lower octave (octave from C2), and a key row B of row B composed of grip keys 4 and 5 is provided. Is a key sequence for designating the octave of C3, and a key sequence C of C rows composed of grip keys 2 and 3.
Is a key sequence that indicates a range one octave higher (octave from C4), and a key row D in the D row composed of grip keys 0 and 1 is a key sequence that indicates a range two octaves higher (octave from C5). . Therefore, for example, if the grip key 2 is pressed while the elbow controllers 8 and 10 are selecting C, a musical tone having a pitch of C4 is generated from the sound source 6, and the grip key 3 is pressed.
Is pressed, the tone having the pitch C4 # is generated from the sound source 6.

Note that the L and R grip controllers 1
Each of the grip controllers 2 and 14 has the same configuration. By operating one of the grip controllers 12 and 14, selection of an octave and selection of natural or sharp can be performed. Further, the key is turned on when any of the grip keys 0, 1,..., 8 is pressed, and is turned off when the pressed grip key is released. When playing, the left and right elbow controllers 8,
10 is mounted on the left and right arms, and the left and right grip controllers 12, 14 are held by the left and right hands, respectively. Therefore, the note name is selected by bending the left arm and the right arm at a predetermined angle, and the octave to be pronounced is pressed by pressing the grip key of the octave to be pronounced of the grip controller gripped at the timing to be pronounced. Will be pronounced. By repeating this operation, a performance can be performed.

The grip keys 0 and 1 are index fingers, the grip keys 2 and 3 are middle fingers, and the grip keys 4 and 5 are provided.
Is the ring finger, and the grip keys 6, 7 are operated with the little finger.
In some cases, four or six grip keys are pressed at the same time. At this time, if the grip keys 0, 2, 4, and 6 sound as if they were pressed, the sound is erroneously generated. In the present invention, the erroneous sound is prevented as follows.

That is, the grip keys that are erroneously pressed at the same time are limited to even-numbered grip keys of 0, 2, 4, and 6 (in this case, “0” is also an even number). Is detected, it is detected whether or not the grip key of the number one greater than the grip number is pressed, and if it is pressed, it is determined that the even-numbered grip key is erroneously pressed. It suppresses pronunciation. As a result, it is possible to prevent erroneous sound generation due to erroneous pressing of a grip key arranged close to the grip key arranged close to the far side.

Next, the operation of the tone control device will be described with reference to a flowchart. The flowchart shown in FIG.
7 is a flowchart of a main routine executed by the PU1. When the power of the musical tone control device is turned on, the main routine is started, and initialization is performed in step S10 to clear various registers, set the sound source 6, and the like. Will be Next, in step S20, a grip key process for detecting which grip key has been pressed is performed.
Next, a belt switch process is performed in step S30. This belt switch (SW) is connected to each S shown in FIG.
It corresponds to W5, and switches the setting of the tone color and the function of the grip controller. The tone control device is a belt switch because it can be mounted on a belt except for each controller.

When the belt SW process is completed, step S
At 40, a branch is made to step S50 every time a predetermined time elapses. At step S50, the bending angles of the left and right elbow controllers 8, 10 are detected and set to EL and ER, respectively. Next, based on the EL and ER set in step S60, control such as generation of a pitch name is performed. In this case, EL and ER are values obtained by converting analog operation amounts into digital data. When the process in step S60 ends, the process returns to step S20, and the processes in steps S20 to S60 are executed in a cyclic manner. If it is determined in step S40 that the predetermined time has not elapsed, the process proceeds to step S20.
To step S until a predetermined time has elapsed.
Steps S20 and S30 are repeatedly performed.

Next, FIG. 3 shows a flowchart of the key-on event process. This process is executed when a key-on event is detected. When the key-on event process is started, “0” is set to “i” in the case of the left elbow controller, and “1” is set to “i” in the case of the right elbow controller in step S100. The number of the grip key shown in FIG. 4 is set to j. Then, step S1
At 10, it is determined whether or not j is an even number. If it is not determined that it is an even number, the flow branches to step S130 to mute the j-1th grip key. When j is an odd number, the j-th and j-1 grip keys are operated by the same finger as shown in FIG.
This is because, when the first grip key is pressed first and then the j-th grip key is pressed, the j-th grip key is erroneously pressed and the sound is forcibly muted. Here, if the j-1st grip key is not pressed, there is no sound to be silenced, so step S130.
No action is taken.

Next, in step S140, sound assignment is performed, the sound processing for the j-th key is performed in step S150, and the key-on event processing ends. If j is determined to be an even number in step S110, the process proceeds to step S110.
The process proceeds to 120, where it is determined whether or not the j + 1th grip key is turned on. If it is determined that the grip key is turned on, it is determined that the grip key has been turned on by mistake and the process is terminated as it is. If it is determined that the j + 1-th grip key is not turned on, the process branches to step S140, where sound generation is assigned in step S140, and sound generation processing for the j-th key is performed in step S150. The key-on event processing ends. In this way, the tone control device of the present invention detects when two grip keys are pressed by one finger by mistake and prevents erroneous sound generation.

Another example of key assignment of eight grip keys 0, 1, 2,..., 8 arranged in four rows and two columns in the grip R controller 12 and the grip L controller 14 is shown in FIG. Shown in Grip key 0 on the side closer to the base of the finger has a closed hi-hat cymbal (HH close), and grip key 2 has an open hi-hat cymbal (HH close).
open) but the grip key 4 has a snare drum (SD1)
However, a ride cymbal (Ride) is assigned to the grip key 6. Also, the grip keys 1 on the far side
Toms 1, 3, and 3 are assigned to 3, 5, respectively, and a crash cymbal is assigned to the grip key 7.

The functions of the grip controllers 12 and 14 are switched by the respective switches SW5, and the thus-assigned grip R controller 12 and grip L
When playing a drum using the controller 14,
Since the scale is fixed, the volume may be controlled by, for example, the elbow L controller 10, and the depth of the effect, the speed of rising, and the like may be controlled by the elbow R controller 8. In the above description, the tone signal generated by the sound source 6 is transmitted wirelessly. However, the tone signal may be transmitted not only wirelessly but also by wire. Further, the tone control device of the present invention may be configured such that CPUs are provided in the left and right grip controllers as shown in FIG.

[0028]

As described above, according to the present invention, when the second key arranged on the side far from the base of the finger is operated, the first key adjacent inside is operated. Is detected, the generation of a musical tone corresponding to the first key is suppressed, so that erroneous sound generation can be prevented and the playability can be improved.
