[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a musical sound control apparatus according to an embodiment of the present invention. In this figure, reference numeral 1 denotes a hand detection unit for detecting the bending angle of each finger and the bending angle of a wrist of a player's hand. Yes, as shown in FIG.
And gloves 1a mounted on the right hand of the player, the finger sensor 1b is attached to the back part of each finger of the glove 1a ₁ ~1b ₅
And the wrist sensor 1c attached to the back of the wrist
It is composed of

[0008] 2 A / D converter for converting the analog signals output from the finger sensor 1b ₁ ~1b ₅ and listed sensor 1c into digital data, 3 C
A one-chip microcomputer including a PU (Central Processing Unit), a program ROM, a RAM in which various data are temporarily stored and a RAM in which various registers and flags are secured, and an I / O interface; A functional switch group composed of switches, 5 is a display composed of a liquid crystal display or the like, and 6 is a MIDI transmitter that transmits MIDI information output from the microcomputer 3.

Reference numeral 7 denotes a MIDI standard guitar, which outputs various kinds of MIDI information by a player's operation. For example, a note-on signal including data indicating the pitch of the fret pressed by the finger when the player plays the string is output, and a note-off signal is output when the vibration of the string decreases. Reference numeral 8 denotes a transmitter for transmitting various signals output from the guitar 7.

[0010] In addition, 9 is a MIDI receiver for receiving a signal transmitted from the MIDI transmitter, 10 is a receiver for receiving a signal transmitted from the transmitter 8, and 11 is data such as note-on and note-off output from the receiver 10. The sound source 12 outputs a tone signal. The effector 12 is controlled by a control signal output from the MIDI receiver 9, processes the tone signal output from the sound source 11 in various ways, and outputs the processed signal. This is a sound system including an amplifier, a speaker, and the like that generate a musical tone by inputting a musical tone signal to be input.

In such a configuration, first, as shown in FIG. 3, 32 combinations of bending and stretching of five fingers from the thumb to the little finger are changed from program change number 1 for controlling switching of MIDI standard effects and the like. Up to 32 are supported. Then, in the effector 12, by assigning and storing 32 types of effects in advance corresponding to each program change number, it is possible to select an effect corresponding to a combination of bending and stretching of the finger.

For example, as shown in FIG. 4, when only the thumb is bent, the effect 2 of the program change number 2 is selected. By bending the wrist toward the back of the hand in this state, the program change number is transmitted from the MIDI transmitter 6, received by the MIDI receiver 9, and then transferred to the effector 12. The effector 12 switches to the effect corresponding to the program change number. In this embodiment, continuous change data according to the bending angle of the finger can be output in addition to the program change number. For example, MIDI control data for volume control is output.

Next, the operation of the microcomputer 3 will be described with reference to the flowcharts of FIGS. 5, 6, and 8 to 13. When the player wears the hand detection unit 1 shown in FIG. 2 in his right hand and turns on the power to the musical tone control device shown in FIG.
The process proceeds to step SA1 to initialize the components of the apparatus. FIG. 6 shows a routine of this processing. In this routine, in step SB1, after clearing each register and flag of the RAM, step SB2
Proceed to.

In step SB2, after setting various parameters, the process proceeds to step SB3. Step SB
In step 3, the current value of the digital data output from the list sensor 1c and converted in the A / D converter 2 is read, and the value is stored in the register WRIST. Then, the process proceeds to step SB4.

At step SB4, the register WRIST
It is determined whether or not the current output value of the wrist sensor 1c stored in the memory is larger than a preset ON threshold value of the wrist sensor 1c. In this embodiment, the player
For example, as shown in FIG. 4, by bending only the thumb, the effect 2 of the program change number 2 shown in FIG. 3 is selected, and the tone control device enters a standby state. Then, as shown in FIG. 7, the performer switches his / her right wrist to the back of his / her hand while keeping his / her thumb bent, so that the conventional effect is switched to effect 2. Therefore, in step SB4, a threshold value at which the wrist sensor 1c is switched from off to on is set in advance, and the threshold value is compared with the current output value of the wrist sensor 1c so that the player can use the right hand. It is determined whether the wrist has been deflected to the back of the hand more than the threshold value. If this determination is "YES", the flow proceeds to step SB5.

In step SB5, a flag OWON indicating that the previous wrist sensor 1c is in the ON state is set to "1". In this case, since the initialization process is performed, the ON state of the initialization list sensor 1c is set to the flag OWON as the previous ON state of the list sensor 1c.
Is set to 1. This process is performed in the wrist detection process (step SA3) to be described later to determine whether or not there is an event based on whether or not the current state of the wrist has changed from the previous state. Then, the microcomputer 3 returns to the main routine of FIG. 5, and proceeds to Step SA2.

On the other hand, if the result of the determination made at step SB4 is "N
If "O", that is, if the current output value of the wrist sensor 1c stored in the register WRIST is smaller than a preset ON threshold value, the process proceeds to step SB6.
In step SB6, after resetting the flag OWON to 0, the process returns to the main routine of FIG. 5 and proceeds to step SA2.

At step SA2 in FIG. 5, a finger detection process for detecting the bending state of each finger of the player is performed. FIG. 8 shows a routine of this processing. In this routine, in step SC1, after storing 1 (corresponding to the thumb) as an initial value in a variable i corresponding to five fingers, step SC2
Proceed to. In step SC2, it is determined whether or not the variable i is 6, that is, whether or not the detection processing described below has been completed for all five fingers. If the result of this determination is "NO"
In other words, if the variable i is not 6, step S
Proceed to C3.

At step SC3, the current value of the digital data output from the finger sensor 1b _i , in this case, from the finger sensor 1b ₁ and converted by the A / D converter 2, is read, and the value is stored in the register FING _i , for, after storing in the register FING _1, the process proceeds to step SC4. At step SC4, it is determined whether or not the current output value is larger than the threshold of asserted preset finger sensor 1b _i not register FING _i stored in the finger sensor 1b _i. Now if the current finger sensor output values are set in advance of the finger sensor 1b ₁ which is stored in the register FING ₁ 1
b greater than _one-on threshold determines whether the. If the result of this determination is "YES", the flow proceeds to step SC5.

[0020] At step SC5, is set to 1 a flag FON _i indicating that the finger sensor 1b _i is on. In the current case, after the finger sensor 1b ₁ has set a flag FON ₁ to 1 indicating the ON state, step SC
Proceed to 7. On the other hand, the determination result of step SC5 is “NO”
Cases, i.e., register FING _i to the current output value is preset finger sensor 1b _i of the stored finger sensor 1b _i
If it is smaller than the ON threshold value of step SC6, step SC6
Proceed to. In this case, if the current output value of the finger sensor 1b ₁ which is stored in the register FING ₁ is smaller than a preset threshold on the finger sensor 1b _1, the process proceeds to step SC6.

[0021] At step SC6, it resets the flag FON _i indicating that the finger sensor 1b _i is on the zero. In the current case, after resetting the flag FON ₁ indicating that the finger sensor 1b ₁ is in the on-state to 0, the process proceeds to step SC7. In step SC7, after the value of the variable i is incremented by 1, the process returns to step SC2, and the variable i
Is repeated, that is, the processing in steps SC3 to SC6 is repeated for all five fingers. When the processing of steps SC3 to SC6 described above is completed for all five fingers, the result of determination in step SC2 is “YES”.
The microcomputer 3 returns to the main routine of FIG. 5 and proceeds to step SA3.

If this determination is "YES", the flow proceeds to step SD3. In step SD3, the flag NWON indicating that the current wrist sensor 1c is in the on state is set to 1, and the process proceeds to step SD4.

At step SD4, it is determined whether or not the flag OWON indicating that the previous wrist sensor 1c is in the on state has been reset to "0". If this determination is "YES", the flow proceeds to step SD5. In step SD5, the ON event flag ONEVNT, which is set to 1 when there is an ON event, is set to 1, and the process proceeds to step SD9.

On the other hand, if the result of the judgment in step SD4 is "N
If "O", that is, if the flag OWON is set to 1, it is determined that there is no on-event, and the process proceeds to Step SD9. In addition, when the determination result of step SD2 is “N

At step SD6, the flag NWON is set to 0.
After that, the process proceeds to Step SD7. Step S
At D7, the current output value of the wrist sensor 1c stored in the register WRIST is set to a preset wrist sensor 1c.
It is determined whether or not c is smaller than an off threshold value. In the process of step SD7, a threshold value at which the wrist sensor 1c is switched from on to off is set in advance, and the threshold value is compared with the current output value of the wrist sensor 1c, so that the player can use the right hand. It is determined whether the wrist has been bent toward the palm above the threshold. The result of this determination is “YE

It is determined whether or not the value of is zero. The result of this determination is “Y
In the case of "ES", the process proceeds to step SE3. At first, since the value of the event counter EVENT is 0, the process proceeds to step SE3.

At step SE3, the event counter E
1 is stored in VENT, and 1 is set in a count flag COUNT in which 1 is set when the wrist sensor 1c is first turned on within one second.
After setting the value of the time counter TIME to 1000, the process proceeds to step SE6. Here, the timer counter TIME will be described. The value of the timer counter TIME is 1 ms
It is decremented by the timer interrupt processing performed in the cycle of ec. FIG. 11 shows a routine of the timer interrupt processing. In this routine, in step SF1, it is determined whether or not the value of the timer counter TIME is 0 to prevent an underflow of the timer counter TIME.
If the determination result of step SF1 is "NO", that is, if the value of the timer counter TIME is not 0, the process proceeds to step SF2. In step SF2, after decrementing 1 from the value of the timer counter TIME, the process returns to the main routine of FIG.

On the other hand, if the result of the determination in step SE2 is "N
If “O”, that is, if the value of the event counter EVENT is not 0, the process proceeds to step SE4. After the second time, since the value of the event counter EVENT is not 0,
Proceed to step SE4. In step SE4, it is determined whether or not the count flag COUNT is set to 1, that is, 1 after the wrist sensor 1c is first turned on.
It is determined whether it is within seconds. The result of this determination is “YE
In the case of "S", the process proceeds to step SE5.

At step SE5, the event counter E

If the determination result of step SE8 is "YES", that is,
If the value of the event counter EVENT is 1,
Proceed to step SE11.

In step SE11, a program change transmission process for transmitting a program change number corresponding to a combination of bending of five fingers is performed. FIG. 12 shows a routine of this processing. In this routine, in step SG1, the corresponding program change number is stored in the register PROG with reference to the table of FIG. 3 according to the state of the flag FON _i (i = 1 to 5), and

In step SG2, the program change number stored in the register PROG is transmitted via the MIDI transmitter 6, and then the flow advances to step SG3.
As a result, the data is transmitted from the MIDI transmitter 6,
The program change number received by the MIDI receiver 9 is input to the effector 12. Then, the effector 12 switches, for example, the effect so far to the effect 2.

At step SG3, the microcomputer 3 clears the value of the event counter EVENT, returns to the wrist count processing routine of FIG. 10, and proceeds to step SE12. In step SE12, after resetting the count flag COUNT to 0, the process returns to the main routine of FIG. 5 and proceeds to step SA5.

At step SA5, a control change transmission process for controlling the volume and the like in an analog manner is performed. FIG. 13 shows a routine of this processing. In this routine, in step SH1, the mode 2 on flag M2ON

On the other hand, if the result of determination in step SH1 is "YE
If "S", that is, if the mode 2 on flag M2ON is set to 1, the process proceeds to step SH2. At step SH2, the average value of the current value of the bend register NDEP indicating the depth register FING _i finger, i.e., 5

At step SH5, it is determined whether or not the value of the register RDEP is not 0. The result of this determination is “N
If "O", the process returns to the main routine of FIG. 5 without doing anything, and returns to step SA2. On the other hand, if the decision result in the step SH5 is "YES", that is, if the value of the register RDEP is not 0, the process proceeds to a step SH6.

In step SH6, the event counter E

In step SH7, the control change number (for example, the number 7 for controlling the volume) indicated by the value of the event counter EVENT is obtained from the table referred to in the processing in step SH6, and then the process proceeds to step SH8.

In step SH8, after transmitting the control change number and the control data stored in the register CNTL via the MIDI transmitter 6,
