Referring to FIGS. 7 and 8, a method of operating the Miburi performance device will be described. As shown in FIGS. 7 (A) to 7 (C), the player operates the Miburi playing apparatus by moving the left and right arms and wrists. As a specific operation, FIG.
As shown in (B), the upper arm is moved up and down to bend and extend the joint of the shoulder to change the detection value (bending angle) of the shoulder sensor 11, and as shown in FIG. Elbow sensor 1 by bending and extending the joint
2, an operation of changing the detection value of the wrist sensor 13 by bending the wrist joint by bending the hand back and forth as shown in FIG. In addition, the grip unit 20 operates the seesaw controller 21 with the thumb as shown in FIG.
The key 22 is turned on and operated with the index finger to the little finger. When the seesaw controller 21 is operated, control data (modulation, after touch, etc.) corresponding to the operation angle is generated. When the key 22 is turned on, a note-on signal of a percussion instrument sound assigned to the key is generated. Generated.

Referring to FIG. 8, the sound generation operation using various sensors (shoulder sensor 11, elbow sensor 12, wrist sensor 13) will be described. Here, FIG. 8 shows only the trigger generation operation using the elbow sensor 12. As the sounding operation, there are a stop mode operation and a cross mode operation, and the Miburi performance device can set either a stop sounding mode for receiving the stop mode operation or a cross sounding mode for receiving the cross mode operation. This setting is performed by a sounding mode selection switch. FIG. 3A shows a stop mode operation. In stop mode operation, the forearm is operated at a certain speed (speed threshold) or more and then stopped (stop).
At this time, the detection value of the elbow sensor 12 does not change after it changes at a certain speed or more. In the stop sounding mode, when such a change is detected, a note-on signal is generated as a sounding operation. The swinging direction may be either upward or downward. Fig. (B)
Indicates a cross mode operation. The cross mode operation is an operation of increasing the bending angle of the forearm (elbow joint) to the upper cross point or more and an operation of extending the bending angle to the lower cross point or less. When the bending angle exceeds the upper cross point, the detection value of the elbow sensor 12 exceeds the upper threshold, and when the bending angle exceeds the lower cross point, the detection value of the elbow sensor 12 exceeds (below) the lower threshold. . When a detection value in this range is input in the cross sounding mode, a note-on signal is generated as a sounding operation. The speed threshold, the upper threshold, and the lower threshold can be set by the user for each sensor, and the set values are stored in a register set in the RAM 33.

Although the operation of the right elbow and the sound generation operation by the right elbow sensor 12R have been described with reference to FIG. 8, a note-on signal is generated by the same operation for all the sensors from the right shoulder sensor 11R to the left wrist sensor 13L. Thus, the percussion instrument sound assigned to each sensor can be generated.

Here, the contents stored in the RAM 33 will be described with reference to FIG. This figure shows a register group used in the edit mode. The edit mode flag EM is a flag indicating whether the current mode is the edit mode or the performance mode. The edit mode is a mode for changing the content of the tone control information such as the tone color and the parameters assigned to each sensor key as described above. The sounding mode flag TM is a flag indicating whether the current sounding mode is the stop sounding mode or the cross sounding mode. If TM = 0, it is the stop sounding mode, and if TM = 1, it is the cross sounding mode. The angle detection value register ANG is a register for storing a detection value (bending angle) of each sensor, and is provided for each of the left shoulder sensor 11L to the right wrist sensor 13R. The designated sensor register SS is a register for storing the number of the sensor or key designated as the musical sound control information to be edited. The designation information register SP is a register for designating which information of the tone control information set for the sensor or key designated as the edit target is to be changed. The parameter register is a register for storing various parameters such as volume, touch curve, and sensor sensitivity set for each sensor. The tone color assignment table is a table that stores tone colors assigned to each sensor.

FIG. 6 is a diagram showing the tone color assignment table. As shown in the drawing, a plurality of types of tone color assignment tables are set for each genre, and can be switched by operating switches provided on the seesaw controller 21 and the control unit 30. In each tone color assignment table, the left and right forefinger to little finger (LGRP2-5, RGRP2-5) and left and right wrist sensors (LWST, RWST), left and right elbow sensors (LELB, RELB), and right and left shoulder sensors (LSL)
LD, RSLD) are assigned tones such as rock tom 5, hi-hat close, and the like. It should be noted that a tone that is not frequently used in the operation of the genre can be assigned (turned off) so as not to erroneously generate a musical tone.

At the time of performance, one of the tone color assignment tables is designated, and the tone color is determined by referring to the tone color assignment table in accordance with the trigger of each sensor or the switch being turned on. When the edit mode switch provided on the control unit 30 is turned on, the edit mode is set, and the contents of the tone color assignment table designated at that time can be individually rewritten.

FIGS. 9 to 11 are flowcharts showing the operation of the control unit of the miniature playing apparatus. FIG. 9A shows a main routine. When the power supply of the mibri performance device is turned on, an initial setting operation such as resetting a register is performed (s1), and thereafter, an angle sensor process (s2), a grip process (s3), a belt switch process (s4), and others. The processing operation of the process (s5) is repeatedly executed. The angle sensor processing (s2) is an operation of detecting the bending angles of the left and right shoulder sensors 11L and R, the elbow sensors 12L and R, and the wrist sensors 13L and R, and generating a note-on signal according to the detected value and the sound generation mode. (See FIG. 10). The grip processing (s3) is performed by the seesaw controller 21 and the key 22 of the grip unit 20.
This is an operation of detecting the operation content and performing a corresponding process (see FIG. 11). The belt switch processing (s4) is shown in FIG.
As shown in (B) to (D), the control unit 30
This is a process corresponding to the operation of various switches provided in. The other process (s5) is a display change process corresponding to the switching of the mode and the timbre.

FIG. 9B shows an operation corresponding to turning on of the edit mode switch. When the edit mode switch is turned on, the edit mode flag EM is inverted (s10). As a result of this inversion, when the EM is set to “1”, the start of editing is transmitted to the tone generator 60 (s12), and the display 36 of the control unit 30 is displayed to indicate that it is in the edit mode (s13). . When the EM is reset to "0" as a result of the EM inversion of s10, the end of editing is transmitted to the tone generator 60 (s14), and the display 36 of the control unit 30 indicates that the normal performance mode is set. Is displayed (s15).

FIG. 9C shows an operation corresponding to turning on of the tone generation mode selection switch. When the sounding mode selection switch is turned on, the sounding mode flag TM is inverted (s20), and the current sounding mode is displayed on the display 36.

FIG. 9D shows an operation corresponding to turning on of the parameter designation switch. This operation is valid only in the edit mode. When the tone control information designation switch is turned on, the value of the designation information register SP is counted up by one. The designation information register functions as a pointer for indicating the tone control information to be edited. In the operation of s25, when SP reaches the maximum value, it is reset and returns to 1. Then, the tone control information indicated by the SP is designated as tone control information to be edited by processing such as reading out to a buffer (s26), and the current value of the tone control information is displayed on the display 36 (s2).
7).

It is assumed that the tone control information includes various parameters such as tone color designation data, tone color control parameters, and sensor sensitivity. In the edit mode, the setting of the tone control information designating switch can be omitted, and when omitted, the timbre (timbre designation data) is designated as an edit target by default.

FIG. 10 is a flowchart showing the sensor processing. Although this flowchart describes only the operation corresponding to one sensor, the operation is repeatedly executed for each of the left shoulder sensor 11L to the right wrist sensor 13R. First, the sensor detection is fetched and stored in the angle detection value register ANG (s30). And
The sound generation mode is determined (s31), and the cross sound generation mode (T
If M = 1), the operation proceeds to the operation of s32 or less, and if the stop sound generation mode (TM = 0), the operation proceeds to the operation of s36 or less.

In the case of the cross tone generation mode, ON / OFF is determined by comparing ANG with an angle threshold value (s32). This threshold value is set for each tone color TP assigned to this sensor by the tone color assignment table.
If it is an ON event, a note-on signal is generated based on the TP and transmitted to the sound source device 60 (s34).
The identification number of this sensor is set in the designated sensor register SS (s35).

In the case of the stop sound generation mode, the moving (MOVE) or the stop (STOP) is determined from the rate of change of ANG (s36), and if the event is a stop event, a note-on signal is generated based on the TP designated by this sensor. Is generated and transmitted to the tone generator 60 (s38), and the identification number of this sensor is set in the designated sensor register SS (s39).

Writing to the designated sensor register SS is effective only in the edit mode, and the tone control information set for the designated sensor can be changed by operating the seesaw controller 21 described later. That is, in the edit mode, the sensor (tone control information) to be edited can be specified by the sound generation operation in the performance mode, and the tone is generated in the same manner as in the performance mode. Can be confirmed by ear.

FIG. 11 is a flowchart showing grip processing. Although this operation is shown for only one grip unit, the left and right grip units 20L, 20L
This operation is sequentially performed on R. First, the state of each key is detected (s41). When an ON event occurs in any key (s42), a note-on signal is generated based on the tone color TP assigned to the key and transmitted to the tone generator 60 (s43). Then, the key number is set in the designated sensor register SS (s4
4).

Next, the angle of the seesaw controller 21 is detected (s45), and it is determined whether or not the mode is the edit mode (s46). If not in edit mode (E
(M = 0), the normal seesaw controller corresponding processing is executed (s47). The normal seesaw controller compatible processing is a processing operation for executing a function stored in the tone color assignment table. For example, a modulation signal is generated and transmitted to the tone generator 60, or an after-touch signal is generated to generate a tone signal. 60. On the other hand, if the mode is the edit mode (EM = 1), it is determined whether the angle of the seesaw exceeds a predetermined threshold value (s48). If it exceeds the predetermined threshold value, it is an instruction to change the tone control information to be edited.
The value of the tone control information set in the key specified by SP is changed (s49). This change
For example, the operation is +1 when the angle of the seesaw exceeds the positive threshold value, and -1 when the seesaw angle exceeds the negative threshold value. Then, each time the tone control information is changed, it is determined whether or not the confirmation sound is generated, that is, whether or not the confirmation sound switch is set to the sound generation side (s50). If it is set to sound, a note-on signal for confirmation is generated based on the designated tone color TP and transmitted to the tone generator 60 (s51).

As described above, since the tone for confirmation is generated when the tone control information is changed, it is possible to judge audibly whether or not the tone control information is appropriately changed. If the changes are not appropriate, further changes can be made. In addition, by setting whether or not to sound confirmation, in the case of delicate parameter changes, the confirmation sound is not generated every time the parameter is changed, and the sound is generated according to the sounding mode after changing appropriately. It is also possible to confirm by sounding.

The parameters changed in the edit mode are not limited to the timbre, but may be any parameters such as a touch curve, a volume, and a pan. When changing the tone, the mode is set to the mode that sounds confirmation every time the tone is changed,
When changing a normal parameter, a mode in which confirmation sound is not generated may be set as a default.

In the above embodiment, the miburi playing device and the sound source device are set so as to emit percussion sounds. However, the types of musical sounds are not limited to this, and musical sounds having musical scales are generated. Is also good.

In the above-described embodiment, the tone color assignment table is provided in the control unit 30 attached to the belt and the sound source is provided in the stationary sound source device. May be transmitted wirelessly and received by an FM receiver or the like for listening. Further, a tone assignment table is provided in the tone generator 60, and only the sensors and keys turned on / off are transmitted from the control unit 30, and the tone assignment and editing are processed as operations of the tone generator. It may be.

In the above embodiment, the tone control information is changed by the seesaw controller 21. However, the setting may be changed by using any one of the keys 22. In the above-described flowchart, the edit mode operation is all performed by operating the mibri performance device, but the edit mode may be allowed to change settings by panel operation. In this case, the setting can be changed by using both the panel operation and the operation of the mibri performance device.

In the above embodiment, the tilt angle of the seesaw output from the seesaw controller 21 is determined in three stages, and the tone control information is controlled to +1, no change, and -1, respectively. The determination may be made in four or more stages and the control corresponding to each angle may be performed. For example, determination is made in five steps, and processing of +10, +1, no change, -1, -10 is performed.

[0041]

As described above, according to the first aspect of the present invention,
In the edit mode, the sensor means (musical tone control information) to be edited can be designated by the same operation as the sounding instruction, so that the designation can be easily performed by an easy-to-understand operation. In addition, since the designated musical tone control information can be changed using the grip playing means, the setting can be changed more easily than when a panel switch or the like is operated.

Further, according to the second aspect of the present invention, when the tone control information is changed by the setting changing means, the tone is generated based on the changed tone control information. Can be confirmed audibly.
