DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical tone control device capable of controlling musical tones according to, for example, movements of a player's fingers.

[0002]

2. Description of the Related Art In recent years, there has been proposed a musical tone control device which controls a musical tone in accordance with a detection signal output from the sensor by attaching or holding a sensor for detecting body movement to a part of a human body. Various types have been developed. Such a tone control device is disclosed in, for example, JP-A-1-291290 and JP-A-2-22898.

[0003] Of these publications, the former discloses a tone control apparatus called a finger type, which includes an operation detecting means for detecting a bending / extending operation of a joint of each finger. As shown in FIG. 3, the movement detecting means is provided on a stretchable glove-shaped wearing tool 31 and finger sensors 31a to 31a provided on each finger portion of the wearing tool 31 to detect a finger bending sensor.
1e. Each finger sensor 31a to 31e
Output detection signals corresponding to bending and extension of each finger joint, and each detection signal is converted into tone control data such as key-on / key-off and key code.

[0004] On the other hand, the latter is gripped by a player's hand,
There is disclosed a musical tone control device provided with a performance operator operated by each fingertip. Here, the performance operator is called a grip-type operator. FIG. 4 (a), (b)
3A and 3B are a perspective view and a front view, respectively, showing the appearance of the grip type operation element. As shown in this figure, in the grip type, the button switches SR1 to SR8 pressed by the fingertips of the fingers (the index finger to the little finger) of the player on the operation surface 41a of the box-shaped case 41, and the main switch operated by the thumb An operator 5R is provided. The player switches each of the button switches SR1 to S
When R8 is pressed, an operation signal corresponding to this is generated. Then, this operation signal is converted into the above-mentioned musical tone control data. Further, in this example, the musical tone control data is independently controlled in accordance with the operation of the main operator 5R, thereby realizing an advanced performance accompanied by designation of sound effects, chords and the like.

[0005]

By the way, in the above-described tone control device, the operation detection data (the finger sensors 31a to 31e, the button switches SR
The conversion processing unit for converting the operation signals from 1 to SR8 into actual tone control data is not provided in the motion detecting means in order to improve the performance operability by reducing the size and weight of the motion detecting means. It is provided in the tone control device main body (which may have tone generating means) separately from the motion detecting means. Then, the detection data from the operation detecting means is transferred to the apparatus main body and converted into musical tone control data to perform musical tone control. When the detection data is converted to the tone control data, the manner of the conversion differs depending on the type of the motion detection means. That is, the above-mentioned finger type and grip type are different from each other in the mode of performance and the playing style, and accordingly, the above-described conversion mode is also different. Therefore, when selectively using different types of motion detection means for the apparatus main body, the mode of conversion of the detection data into musical tone control data in the apparatus main body depends on the type of motion detection means actually connected. Need to change. For this reason, conventionally, a designation switch for designating a conversion mode (playing style) of detected data into musical tone control data has been provided in the apparatus main body.

However, in the conventional tone control device, the performer specifies the rendition style (data conversion mode) regardless of the type of motion detection means connected to the device main body. In some cases, the player may specify a playing style that does not match the type of the connected motion detecting means. For this reason, for example, despite the fact that the above-mentioned finger-type motion detection means is connected,
When a playing style corresponding to the grip type motion detecting means is specified, the supplied detection data is subjected to data conversion processing corresponding to an inappropriate playing style, resulting in a malfunction.

The present invention has been made under such a background, and an object of the present invention is to provide a tone control device which can always perform tone control suitable for the type of motion detecting means.

[0008]

In order to solve the above-mentioned problems, the present invention has an operation detecting means for detecting a performance operation and generating detection data in accordance with the performance operation.
In a tone control device that generates tone control data corresponding to the detection data, an identification data generation unit that is provided in the operation detection unit and generates identification data indicating a type of the operation detection unit, based on the identification data, A conversion unit for converting the detection data into musical tone control data in accordance with the type of the motion detection unit represented by the identification data. Also, the present invention provides a rendition style data supply means for supplying rendition style data for converting the detection data into musical tone control data to the conversion means, and a plurality of rendition style data which the rendition style data supply means supplies to the conversion means. And rendition style data selection means for selecting from among the rendition style data. Further, according to the present invention, the rendition style data selection means can select only rendition style data corresponding to the type of the motion detection means represented by the identification data from the plurality of rendition style data based on the identification data. It is characterized by. Further, the present invention is characterized in that the rendition style data selection means is built in the motion detection means. In addition, the present invention

[0009]

According to the present invention, the identification data generation means generates identification data indicating the type of the motion detection means, and the conversion means determines the type of the motion detection means represented by the identification data based on the identification data. Correspondingly, the detection data generated by the operation detecting means is converted into tone control data. Thereby, the tone control corresponding to the type of the motion detecting means is always performed.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. A: First Embodiment FIG. 1 is a block diagram showing a configuration of a tone control device according to a first embodiment of the present invention. In this figure, reference numeral 1 denotes a motion detecting device for detecting the movement of each finger of a player. For example, any one of the grip-type or finger-type motion detecting means described above is selectively used in the device body 10 (described later). ). The motion detection device 1 generates detection data Dd corresponding to the movement of each finger of the player, and outputs identification data Di indicating its own detection mode. Here, the identification data Di is, for example, data indicating whether the motion detection device 1 is a grip type or a finger type.

Next, each part constituting the apparatus main body 10 will be described. First, reference numeral 2 denotes a signal discriminating unit which detects the detection data Dd and the identification data D output from the operation detecting device
i, the detection data Dd is extracted from the received data and output to the terminal TA, and the identification data Di is extracted and output to the terminal TB.

Here, the communication system performed between the operation detecting device 1 and the signal discriminating unit 2 includes, as described below,
Either a digital synchronous communication system or a digital asynchronous communication system is employed. Digital Synchronous Communication System First, the synchronous system is a system in which the receiving side (the signal discriminating unit 2) identifies a 1-bit segment based on a synchronous clock signal transmitted from the transmitting side (the operation detecting device 1). In this case, the transmission side sets a synchronization code (SYN) of a predetermined byte at the beginning of the transmission data.
Is transmitted, and the receiving side determines the start of transmission data by receiving the synchronization code. Then, for example, assuming that 256 clocks of the synchronous clock signal are one cycle of the transmission data, the transmitting side determines the data for identification (for example,
8 clocks), the receiving side determines that the subsequent data is the detection data Dd or the identification data D
i can be determined.

Digital Asynchronous Communication System In this asynchronous system, the transmitting side adds a start bit and a stop bit to the beginning and end of transmission data (for example, 1 byte), and the receiving side determines the start and end of the transmission data. Things. In this case, for example, when the transmission data is one byte, of the eight data bits, the first one bit is used as a discrimination bit for the data type, and the remaining seven bits are used as detection data Dd or identification data Di. I do. Here, for example, when the discrimination bit is “1”, the remaining 7 bits are used as the detection data D
When the discrimination bit is “0”, the remaining seven bits may be regarded as the identification data Di.

An operation unit 3 includes selection switches A to D and a display unit (not shown) for displaying a selection range and a selection result of each of the selection switches A to D. Here, the selection switches A to D have four different playing styles I to IV, respectively.
And outputs an ON signal according to the operation. In the first embodiment,
When the finger type motion detection device 1 is used,
The playing styles I and II correspond, and in the case of the grip type motion detection device 1, the playing styles III and IV correspond.

The operation unit 3 is configured to display a selection range and a selection result of the selection switches A to D on a display unit in accordance with a control signal Cs described later.
The display unit includes, for example, an LED (light emitting diode) for each of the selection switches A to D, and displays a selection range, that is, a switch corresponding to a rendition style to be selected, and a switch actually operated. Each color is displayed differently.

Next, reference numeral 4 denotes an input selector. The input selection unit 4 generates the above-described control signal Cs according to the above-described identification data Di, and also generates the rendition style data Ds based on the ON signal supplied from the operation unit 3. That is, the input selection unit 4 generates a control signal Cs for representing a rendition style that matches the detection mode of the motion detection device 1 from the identification data Di, and supplies this to the operation unit 3. further,
The input selection unit 4 selects and outputs one of performance style data corresponding to various preset performance styles in accordance with an ON signal supplied from the operation unit 3. Therefore, the rendition style data Ds conforms to the mode of the motion detection device 1.

In this case, the input selection unit 4 outputs the identification data D
A selection switch A for selecting and specifying a rendition style (conversion mode of the detection data Dd) that does not correspond to the type of the motion detection device 1 represented by i.
The switch-on signal by the operations of .about.D is invalidated, and the rendition style data Ds is not output when an unsuitable selection switch is turned on. Thus, for example, when the grip-type motion detection device 1 is connected, even if the player tries to select the rendition style III by mistake, it cannot be specified.

Reference numeral 5 denotes a tone control unit which converts the detection data Dd according to the given playing style data Ds into the tone control data Dc.
And output. Reference numeral 6 denotes a tone generator, which generates a tone signal based on tone control data Dc supplied from the tone controller 5, performs a sound effect process on the tone signal, amplifies the signal, and amplifies the signal from the speaker SP. Make them pronounce.

According to the above configuration, for example, when the grip type motion detecting device 1 is connected to the device main body 10,
The identification data Di indicating the grip type is output from the motion detection device 1 to the signal determination unit 2. Then, the identification data Di is supplied to the input selection unit 4 after the data type is determined in the signal determination unit 2. Input selector 4
Then, a control signal Cs corresponding to the identification data Di is generated and supplied to the operation unit 3. Thus, the operation unit 3 selects the selection switches A and B as the selection range in this case.
Are displayed, for example, in green. on the other hand,
The selection switches C and D do not display the corresponding LEDs, and are outside the selection range.

When the selection switch A is selected, for example, the display color of the LED corresponding to the selection switch A of the operation unit 3 changes to, for example, red, indicating that a valid selection has been made. At this time, an ON signal corresponding to the selection switch A is supplied to the input selection unit 4. In the input selection unit 4, the rendition style data corresponding to the ON signal, that is, rendition style data Ds corresponding to the rendition style I in this case, is selected and supplied to the tone control unit 5.

Next, when the player grips the grip-type motion detection device 1 and starts the performance operation, detection data Dd corresponding to the motion of each finger of the player is output to the signal discriminating section 2. Then, the detection data Dd is supplied to the tone control unit 5 after the data type is determined in the signal determination unit 2.

Then, the tone control section 5 applies the performance data Ds corresponding to the performance I to the given detection data Dd.
Is performed according to the tone control data D
It is supplied to the tone generator 6 as c. Further, the tone generator 6 generates a tone signal based on the tone control data Dc, and the speaker SP produces a sound corresponding to the tone signal.

It should be noted that the detected data D
The conversion process of d is described in, for example,
Since it is described in Japanese Patent Application Laid-Open No. 1290 and Japanese Patent Application Laid-Open No. 2-228982, a detailed description is omitted here. When the motion detection device 1 is of a grip type, for example, the detection data Dd is determined according to a function allocation mode as described in FIGS. 13 to 19 of Japanese Patent Application Laid-Open No. 2-228698.
May be converted into the tone control data Dc. In each of these function assignments, the modes correspond to the above-described rendition styles I and II. On the other hand, when the motion detection device 1 is of the finger type, for example, the detection data Dd is used as in “Mode 0” and “Mode 1” described in Japanese Patent Application Laid-Open No. 1-291290.
May be converted into the tone control data Dc. The modes 0 and 1 correspond to the above-described rendition styles III and IV.

By the way, when the player indicates, for example, the selection switch C or D outside the selection range, this instruction is not recognized as a valid selection, and the LED corresponding to the specified selection switch remains off. State. In this case, even if the player starts the performance operation, the rendition style data Ds is not supplied to the tone control unit 5, so that the tone control operation is not started and no tone is generated.

On the other hand, when the finger type motion detection device 1 is connected, the selection range is the selection switches C and D corresponding to the rendition styles III and IV. For other actions,
This is similar to the grip type described above.

As an embodiment of the operation unit 3, for example, the operation unit 3 is configured in a touch panel format, and selectable rendition styles are displayed on a panel as selection options. In this way, by touching any of these selection options, a playing style outside the selection range is not specified, and
It is a device with excellent machine interface.

B: Second Embodiment Next, a second embodiment of the present invention will be described. FIG.
FIG. 3 is a block diagram showing a configuration of a tone control device according to the embodiment. In this figure, parts common to the respective parts shown in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 2 differs from FIG. 1 in that an operation unit 3 ′ and an input selection unit (not shown) are provided on the motion detection device 1 side. In this case, in the grip type motion detection device 1, the selection switches a and b of the operation unit 3 'correspond to the rendition styles I and II, respectively, and the finger type motion detection device 1
Then, the selection switches a and b correspond to the playing styles III and IV, respectively.

According to such a configuration, for example, when the grip type motion detection device 1 is connected to the device main body 10 ', the player can select one of the selection switches a and b of the operation section 3'. To specify the desired playing style. here,
When the player specifies the selection switch a and starts the performance operation, detection data Dd corresponding to the performance operation and performance style data Ds corresponding to the performance style I are output to the signal determination unit 2. Then, these data are supplied to the tone control unit 5 after the above-mentioned determination is made in the signal determination unit 2.

In the tone control section 5, the detection data Dd is converted to the tone control data D in accordance with the rendition style data Ds corresponding to the rendition style I.
c and output. Thereafter, after the same processing as in the first embodiment described above, a sound is generated from the speaker SP. If the selection switch b is designated at the start of the performance, the rendition style data Ds corresponding to the rendition style II is supplied to the tone control unit 5, and the performance control is performed in accordance therewith.

On the other hand, when the grip-type motion detecting device 1 is connected to the device main body 10 ', if the player designates the selection switch a, the playing style data Ds corresponding to the playing style III is transmitted to the musical tone control section 5. The performance is supplied and the performance control is performed in accordance with the supplied performance. In this case, when the selection switch b is designated, the rendition style data Ds corresponding to the rendition style IV is supplied to the musical tone control unit 5, and the performance control is performed.

As an embodiment of the operation unit 3 ', for example, a single button switch type selection switch may be provided, and each time the switch is pressed, the style of performance is switched. That is, as in this embodiment, the options are a,
In the case of b, a and b are alternately switched each time the switch is pressed. For example, when the options are a, b,
In the three cases of c, each time the switch is pressed, a, b, and c are switched so as to alternate. Thus, even when the number of options increases, the player only needs to operate one button switch, so that the operability is improved.

In the above-described embodiment, the motion detecting device 1 is not limited to the above-mentioned finger type and grip type, but may be an elbow type which is attached to a player's elbow and detects a bending and stretching operation of the elbow. Other detecting means may be used, and the number of corresponding playing styles may be increased by four or more in accordance with this. Further, for example, a performance technique common to different types of motion detection devices 1 may be selected. The point is that only the rendition style that matches the detection mode of the motion detection device 1 can be selected.

Note that analog transmission may be used between the operation detecting device 1 and the signal discriminating unit 2 in addition to the communication method described above. Further, instead of outputting the detection data Dd and the identification data Di from the motion detection device 1 respectively, if the range of data that the detection data Dd can take depends on the type of the motion detection device (grip type or finger type). Alternatively, the type of the motion detection device may be determined from the value of the detection data Dd.

For example, in the case of the grip type, the change range of the detection data Dd (which may be digital or analog) is set to "0 to 10", and in the case of the finger type, the detection data Dd (which may be digital or analog). ) Is changed to “20 to 30”, and the apparatus main bodies 10 and 10 ′ detect whether the value of the detection data Dd is 10 or less or 20 or more, so as to identify the grip type or the finger type. good.

[0036]

As described above, according to the present invention, the identification data generating means generates identification data indicating the type of the motion detecting means, and the converting means converts the identification data based on the identification data. Since the detection data generated by the motion detecting means is converted into musical tone control data in accordance with the type of the motion detecting means to be represented, the musical tone control adapted to the type of the motion detecting means can always be performed, and the wrong playing style can be used. The effect that a malfunction of the tone control can be avoided is obtained.
