DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical tone control apparatus in which sensors are attached to joints such as shoulders, elbows, and wrists of a person, and a musical tone is instructed based on the movement of those joints.

[0002]

2. Description of the Related Art Conventionally, there has been known a musical tone control device in which a sensor is attached to a joint and a musical tone is instructed based on the movement of the joint. For example, there is an electronic musical instrument provided with a grip-type performance operator held by hand and an angle sensor attached to a joint such as a shoulder, elbow, or wrist. In this electronic musical instrument, when a grip-type performance manipulator (having a plurality of manipulators corresponding to fingers) is operated with a finger, a musical tone is generated in accordance with the operation. Also, a musical tone is generated based on the movement of the joint. There are roughly two types of methods for generating musical tones based on joint movements. One method is to generate a musical sound when the bending angle of the joint exceeds a predetermined threshold. The other is a method of generating a musical tone when the bending operation of the joint stops.

[0003] The tone color of a generated tone is determined by selecting a tone color set. One tone color set includes tone color information assigned to each of the operators corresponding to each finger of the grip-type performance operator, and tone color information assigned to each joint. To change the timbre, it is necessary to specify the timbre set again.

On the other hand, there is an electronic musical instrument in which an acceleration sensor is mounted on a rod-shaped member and generates a musical tone every time a predetermined acceleration is detected. This electronic musical instrument has a button dedicated to tone color switching, and switches a tone color generated by pressing the button.

[0005]

By the way, in an electronic musical instrument that generates a musical tone in accordance with the movement of a joint as described above,
Since a musical tone is generated in accordance with the movement of a person, there is a case where the audience wants to show that a part of the music is being played with a predetermined joint movement. Therefore, there is a case where it is desired to temporarily change the tone assigned to the joint to a predetermined tone. For example, when a fill-in is inserted at a specific measure in a song, the sound played by the fill-in is temporarily changed to the wrist in that measure to effectively "show" the performance at that fill-in. There was a request to assign to an angle sensor.

However, since the tone color is changed by designating the tone color set, there is a problem that the tone color cannot be easily changed in real time.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a musical sound control device for instructing the generation of musical sounds based on the movement of a joint so that the tone colors assigned to the joints can be temporarily changed by a simple operation.

[0008]

In order to achieve this object, a musical tone control device according to claim 1 is provided for a plurality of fingers, each of which is assigned a predetermined tone color in advance.

Parts other than 05L, 103R, 104R, and 105R are
It is arranged on the belt part. The player wears the belt portion on the waist, wears the corresponding angle sensors on the left and right wrists, elbows, and shoulders, and performs the performance while holding the grip operator in his hand.

An outline of functional specifications of the electronic musical instrument will be described. This electronic musical instrument has two modes: a normal performance mode and a ghost mode.
It has two modes. Furthermore, the ghost mode has two sub-modes: a left and right independent ghost mode and a left and right joint ghost mode. Switching between these modes is performed by the ghost mode SW
117. The initial state immediately after the power of the electronic musical instrument is turned on is the normal performance mode. In the normal performance mode, if there is an ON event of the ghost mode SW 117, the mode shifts to the left and right independent mode. In the state of the left and right independence mode, if there is an ON event of the ghost mode SW 117, the mode shifts to the left and right combination mode. In the state of the left and right congruence mode, if there is an ON event of the disguise mode SW 117, the mode returns to the normal performance mode.

In the normal performance mode, each grip SW 118 and each angle sensor 103L, 103R,
The sound is generated in the tone colors assigned to 104L, 104R, 105L, and 105R. The pre-assigned tone colors are tone colors selected by a tone color set selection switch (not shown) (included in the display / SW unit 111). Here, it is assumed that tone colors are assigned as follows. . Note that the followings correspond to the numbers of the eight grips SW118 in FIG.

… HH (Hi-Hat) Close… HH Close… HH Open… HH Open… HH Pedal… Tom 1… Crash… Tom 2 Left List (Wrist)… HH Close Right List… HH Close Left Elbow (Elbow)… Snare Right Elbow: Snare Left shoulder (shoulder): Bassdora Right shoulder: Bassdora

Therefore, for example, in the normal performance mode, if there is an ON event of the grip SW 118, H
An H-closed tone is generated, and an HH-opened tone is generated when the grip SW 118 is turned on.
Further, in the normal performance mode, operating the left wrist generates an HH close tone, and operating the left elbow generates a snare tone. The generation of a musical tone based on the movement of the joint is specified in advance when the bending angle of the joint exceeds a predetermined threshold value or when the bending operation of the joint stops. However, in the following description, it is assumed that a method of generating a sound when the bending operation of the joint is stopped (this operation is referred to as a “stop event” of the joint) is specified. Therefore, in the above example of the left elbow, when the left elbow is bent at a certain speed and the bending operation is stopped, a snare tone is generated.

The ghost mode is a mode in which the tone assigned to the grip SW 118 in the normal performance mode is temporarily assigned to the joint angle sensor. The timbre to be assigned to the angle sensor is temporarily garbled, and is therefore called the garbled mode. In the ghost mode, the grip SW
Reference numeral 118 denotes a SW for temporarily assigning a tone color, not a SW for sounding. Therefore, even if the grip SW 118 is turned on in the ghost mode, no sound is produced. Hereinafter, the left-right independent mode and the left-right combined mode will be described.

In the left and right independent mode, when there is an ON event of any of the grips SW118 on the left hand side, the tone assigned to the turned on grip SW118 is temporarily changed to the angle sensor of the left joint (left list, Left elbow, left shoulder). For example, in the left / right independent mode, when there is an ON event of the grip SW 118, which is the left hand grip SW, the HH open assigned to this is temporarily assigned to the left list, the left elbow, and the left shoulder. . Therefore, thereafter, the operation of the left wrist, the left elbow, and the left shoulder generates an HH open musical tone.

The same applies to the right hand side. That is,
In the left and right independent mode, if there is an ON event of any of the grips SW118 on the right hand side, the tone assigned to the turned on grip SW118 is temporarily changed to the angle sensor of the right joint (right list, right elbow, right elbow, Assigned to the right shoulder). In the left and right independent mode, the temporary assignment on the left hand side and the temporary assignment on the right hand side can be specified independently for the left and right sides. It is "garbage" independently of the left and right.

In the left and right congruence mode, if there is an ON event of any of the grip SWs 118 (either the left hand side or the right hand side), the turned on grip SWs
The tone assigned to 118 is temporarily assigned to the angle sensors (left list, left elbow, left shoulder, right list, right elbow, right shoulder) of both the left and right joints. For example, in the left and right congruence mode, if there is an ON event of the grip SW 118 that is the left hand grip SW, the H temporarily assigned to this is set.
H open is assigned to all angle sensors. Therefore, thereafter, the HH open musical tone is generated by the operation of any joint to which the angle sensor is attached. Since both the left and right angle sensors are "altogether" at once, they are called "joint".

Next, a register used in the electronic musical instrument will be described. (1) BM: a mode register that stores mode information indicating the current mode. 0 indicates a normal performance mode, 1 indicates a left and right independent mode, and 2 indicates a left and right combined mode. (2) TEL: An assigned timbre register that stores a timbre number indicating a timbre assigned to the left elbow angle sensor in advance by selecting a timbre set. This T
The assigned tone color register similar to the EL
And it is provided corresponding to each angle sensor. (3) BL: A tone color register that stores a tone number indicating a tone color of a tone generated based on the detection result of the left angle sensor. Specifically, when the motion of the left joint is detected by an arbitrary left angle sensor and BL is “0”, the sound is generated in a tone previously assigned to the angle sensor by selecting a tone color set in advance. . When the BL is other than “0”, the tone is generated with the tone of the tone number set for the BL. (4) BR: A tone color register similar to BL described above for the right side. In the above description of BL, “BL” is replaced by “BR”.
Then, "left side" may be read as "right side". (5) SN: a register for storing the number of the grip SW having an on event or an off event. (6) EL: a register for storing the angle value detected by the left elbow angle sensor.

Note that the symbol indicating the register indicates the register itself as well as the data stored in the register. For example, "EL" indicates the register itself and also indicates an angle value detected by the left elbow angle sensor stored in the register.

Next, the operation of the electronic musical instrument will be described in detail with reference to FIGS.

FIG. 2 shows the main routine. When the power of the electronic musical instrument is turned on, the CPU 107 proceeds to step 20.
In step 1, initialization of various registers is performed. BM, B
L and BR are initialized to “0”. In step 202, grip key processing is performed, and in step 203, belt SW processing is performed.

In the grip key processing of step 202,
An ON or OFF event of the grip SW 118 or the ghost mode SW 117 of the grip operators 115 and 116 shown in FIG. 1 is detected, and a process corresponding to the detected event is performed. FIG. 3 shows the processing when there is an ON event of the garbled mode SW 117, and FIG. 4 shows the processing when there is an ON event of the grip SW 118 (left side).
The processing when there is an off event of W118 (left side) will be described with reference to FIG.

In the belt SW process in step 203, the operation of various switches of the belt portion is detected, and a process corresponding to the detected operation is performed. In particular, when an operation for selecting a tone color set is performed, the tone colors of the grips SW and the angle sensors are assigned as instructed by the tone color set.
Specifically, the tone number indicated by the tone set is set in the assigned tone register provided for each grip SW and each angle sensor (for example, the register TEL is set to the angle sensor of the left elbow of the selected tone set). Set the tone number to be assigned).

Next, at step 204, it is determined whether or not a predetermined time has elapsed. If so, an angle sensor process (to be described later with reference to FIG. 6) is performed at step 205, and then step 202
Return to step 202 if it has not elapsed
Return to The time determined in step 204 is the time in step 2
05 is the time since execution. That is, every time step 205 is executed, the time from that point in time (immediately after the power is turned on, the time after the power is turned on) is measured.
Step 5 is executed. As a result, step 205 is executed at regular intervals. This is because it is necessary to obtain the angle value every certain time when detecting the stop event of the joint with the angle sensor.

FIG. 3 shows the operation of the garbled mode SW on event process. This process is executed when there is an ON event of the ghost mode SW 117 in the grip key process of step 202 in FIG.

First, in step 301, "MOD 3
(BM + 1) "is calculated and set in the register BM.
This means that the current mode value BM is “1” when it is “0”.
, "1" is "2", "2" is "0"
Next, each of the processes is updated. Next, step 30
At 2, the registers BL and BR are reset to "0". In this process, when the mode is changed, the tone color assigned to the angle sensor is initialized to a tone color that has been assigned by selecting a tone color set in advance. After step 302, the process ends.

FIG. 4 shows the operation of the left grip SW ON event process executed when there is an ON event of the left grip SW 118 (first to fourth of the grip SWs 118 in FIG. 1).

First, in step 401, the number of the grip SW having the ON event is set in the register SN. Next, at step 402, the process branches according to the current mode BM. When the BM is “0”, that is, when the current mode is the normal performance mode, in step 403, the tone assigned to the grip SW of the turned on grip SW number SN (the assigned tone color register corresponding to the grip SW concerned). Is transmitted to the sound source 112. As a result, the tone is generated in the tone.

If the BM is "1" in step 402, that is, if the current mode is the left / right independent mode, in step 404, the tone number of the tone assigned to the grip SW of the turned on grip SW number SN Is set in the tone generation tone register BL. BM in step 402
Is "2", that is, if the current mode is the left-right congruence mode, in step 405, the tone color numbers of the tone colors assigned to the grip SW of the turned on grip SW number SN are stored in the tone color tone registers BL and BR. Set to. After steps 403, 404, and 405, the process ends.

Although only the left grip SW ON event processing has been described above, the right grip SW118 is executed when there is an ON event of the right grip SW118 (No. 5 to 8 of the grip SW118 in FIG. 1). The SW on event process is the same procedure. However, in the processing step (step 404) in the case of the left and right independent mode, “BL” is read as “BR”.

FIG. 5 shows the operation of the left grip SW off event process executed when there is an off event of the left grip SW 118 (the first to fourth grip switches 118 in FIG. 1). First, in step 501, the number of the grip SW having the off event is set in the register SN. Next, at step 502, the current mode BM
Branch according to. If BM is "0", that is, if the current mode is the normal performance mode, step 503 is executed.
Then, the tone color registers BL and BR are reset to "0", and the process is terminated.

If the BM is "1" at step 502, that is, if the current mode is the left / right independent mode, at step 504, it is determined whether or not any left-grip SW 118 remains ON. . If no SW has been turned on (all the left grip SWs 118 are off), at step 505, the left tone generation register BL
Is reset to “0”, and the process ends. Step 5
If there is a SW that is turned on in the left grip SW 118 in step 04, in step 506, the last turned on SW among the turned on SWs is determined, and the number of the SW is set in the register SN. I do. And step 5
At 07, the timbre number of the timbre assigned to the grip SW of the SW number SN is set in the tone timbre register BL, and the process ends.

If the BM is "2" at step 502, that is, if the current mode is the left and right combined mode, then at step 508, it is determined whether or not any of the left and right grip SWs 118 remains ON. I do. If no SW is turned on (all left and right grip SW
In step 509, the left and right tone generation registers BL and BR are reset to "0", and the process ends. If it is determined in step 508 that any of the left and right grip SWs 118 has been turned on, the process proceeds to step 510.
Then, the last S turned on among the turned on SWs
W is determined, and the SW number is set in the register SN. Then, in step 511, the tone color numbers of the tone colors assigned to the grip SW of the SW number SN are set in the left and right tone tone registers BL and BR, and the process ends.

The processing shown in FIGS. 4 and 5 (particularly, step 5
06, 507, 510, 511), it is possible to allocate the last-arrival priority in the garbled mode. That is, in the ghost mode, when a plurality of grips SW are turned on, the tone colors of the angle sensors are sequentially changed (changed) to the tone colors assigned to the grip SWs in the order of turning on. Conversely, when the turned-on grip SWs are turned off one by one, the tone of the angle sensor is sequentially changed to the tone assigned to the last turned-on grip SW among the remaining turned-on grip SWs. I will return.

Although only the left grip SW off event processing has been described above, the right grip executed when there is an off event of the right grip SW 118 (the fifth to eighth of the grip SWs 118 in FIG. 1). The SW off event process is the same procedure. However, processing steps in the left and right independent mode (steps 504 to 507)
, "Left" to "right", "BL" to "BR",
Replace with each other.

FIG. 6 shows a detailed procedure of the angle sensor processing executed in step 205 of FIG. First, in step 601, the angle sensor 10 of the left elbow is stored in the register EL.
The angle value detected in 4L is stored. Next, step 60
At 2, the left elbow stop event is detected based on the left elbow angle value EL. When a stop event is detected, the change amount of the angle value EL (step 20 in FIG. 2)
As described in Section 4, since the angle sensor processing of FIG. 6 is executed at regular intervals, the amount of change is obtained by holding the past angle value and calculating the difference from the current angle value.
Detect a stop event based on In particular, the angle value E is set so that sound is produced only when the player intentionally moves and stops the left elbow joint at a speed higher than a predetermined speed.
The case where the amount of change of L becomes equal to or more than the first predetermined value and then becomes equal to or less than the second predetermined value is detected as a stop event.

Next, at step 603, it is determined whether or not there is a stop event. If there is no stop event,
Proceed to step 607. If there is a stop event, it is determined in step 604 whether or not the register BL is not “0”. When the register BL is “0”, note-on of the tone specified by the register TEL (ie, the tone previously assigned to the angle sensor of the left elbow by selection of the tone set) is transmitted to the sound source 112 in step 605. I do. If the register BL is not "0", note-on of the tone specified by the register BL is transmitted to the sound source 112 in step 606. Step 60
After 5,606, the process proceeds to step 607. Step 60
In step 7, the same processing as steps 601 to 606 is performed on the angle sensors other than the left elbow.

According to the embodiment of the present invention described above, the mode is changed to the ghost mode by the ghost mode SW 117, and the timbre assigned to the angle sensor of the joint is temporarily changed only by specifying the timbre by the grip SW 118. be able to. Therefore, the timbre can be instantaneously switched by a simple operation without performing the troublesome operation of switching the timbre set, and the player's usability is improved.

In the embodiment of the present invention described above, the mode is changed to the ghost mode by the ghost mode SW 117, and then the tone is designated by the performance grip SW 118. Instead of providing the ghost mode SW 117, each tone is designated. A garbled SW corresponding to the performance grip SW may be provided. FIG.
Is such an example.

In FIG. 7, reference numeral 701L denotes a left grip operator, and 701R denotes a right grip operator. The left and right grip operators 701L and 701R have performance grip SWs similar to the performance grip SW 118 shown in FIG.
702 (first to eighth SWs). Further, a ghost switch 703 (ninth to sixteenth SW) corresponding to each of the playing grips SW702 is provided. In the figure, SWs arranged on the left and right correspond to each other. That is, the first performance grip SW702 and the ninth ghost switch, the second performance grip SW702 and the tenth ghost SW,..., The eighth performance grip SW
702 and the 16th ghost switch correspond to each other.

In the example of FIG. 7, the timbre of the left and right angle sensors is changed to the timbre assigned to the performance grip SW 702 corresponding to the turned on ghost switch 703 by the on event of the ghost switch 703. For example, the tone assigned to the first performance grip SW 702 is HH
(Hi-hat) Suppose it was closed. A tone color is assigned in advance to the angle sensor of each of the left and right joints (depending on the selection of the tone color set), and before turning on the garbled switch 703, a tone color assigned to the angle sensor of the joint is used according to the operation of the joint. Pronunciation is made. Here, when the ninth ghost switch 703 is turned on, the tone color of the left angle sensor is changed to the tone color assigned to the first performance grip SW 702, that is, HH closed. Thereafter, the movement of the left joint generates a tone for closing the HH. The same applies to the right side. When the ghost switch 703 of the right grip operator 701R is turned on, the tone color of the right angle sensor is changed to the timbre assigned to the playing grip SW 702 corresponding to the turned on ghost switch 703. In order to return the tone assigned to the joint angle sensor to the tone before the transformation, the tone may be reset, for example, by turning on the corresponding performance grip SW.

In this example, the tone color of the joint can be designated by a simple operation (one action) simply by turning on any one of the ghost switches 703, instead of designating the tone color that is changed after the mode is changed by the ghost mode SW. it can.
