Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation of a continuously variable controller such as a slider or a wheel mounted on an electronic keyboard musical instrument by instantaneously changing an output value of a parameter assigned to the controller. The present invention relates to a data output device capable of outputting.

[0002]

2. Description of the Related Art Generally, an electronic keyboard instrument such as a synthesizer is provided with a plurality of sliders (continuously variable controllers) capable of changing predetermined parameters continuously. The slider has a knob that is slidably adjusted, and the parameter assigned to the slider can be continuously changed by operating the knob. For example, if the output frequency of a musical tone is set as a parameter, the frequency of the musical tone to be output can be delicately changed by appropriately adjusting the slider to output a musical tone with a bend effect. be able to.

[0003] Further, when the electronic keyboard instrument is connected to another electronic musical instrument by using MIDI, and tone data set in the electronic keyboard instrument is transmitted to the other electronic musical instrument, for example, a slider is used. If a tone number is assigned to the tone number, the tone number can be sequentially switched to N1, N2, N3,... By adjusting the slider. A predetermined number is set by operating the slider. Data can be transmitted to other electronic musical instruments.

However, in the conventional data output device as described above, by operating the slider, the parameter (frequency or tone number in the above example) assigned to the slider can be continuously changed. However, it cannot be changed instantaneously.
That is, when the frequency is set as a parameter, the pitch can be continuously changed, for example, by 200 cents by operating the slider, but in this case, the pitch gradually changes to reach 200 cents. And cannot directly change the pitch of 200 cents.

A tone number is set as a parameter. When an operation for changing the number from N5 to N10 is performed, N5, N6, N
7, N8, N9, and N10, and therefore, although it is a very short time, unnecessary musical tones (N6 to N6)
9) may be pronounced.

[0006]

As described above, in the conventional data output device, although the parameter can be arbitrarily changed and output by operating the slider, it cannot be changed instantaneously.
There is a disadvantage that data generated in the process of change is output.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to change the parameter output assigned to the slider not continuously but instantaneously and to output it. An object of the present invention is to provide a data output device for an electronic keyboard instrument.

[0008]

To achieve the above object, the present invention provides a data output device for outputting a parameter assigned to a continuously variable controller in accordance with a set value of the continuously variable controller. Mode switching means for switching between the instantaneous output mode and a parameter value assigned to the continuously variable controller, and when the parameter value is changed by operation of the continuously variable controller, the stored content is updated accordingly. Storage means, a trigger means for designating data output timing in the instantaneous output mode, and a parameter value corresponding to the continuous variable controller output when the continuous output mode is selected by the mode switching means. When the instantaneous output mode is selected, the trigger means And output means for outputting the stored contents of said storage means when Ri of the trigger signal is given, is characterized by having a. Further, the trigger means includes:
It operates by a trigger switch installed near the continuously variable controller.

According to the present invention configured as described above, when the "continuous output mode" is selected by the mode switching means,
Since the parameter value that changes according to the operation of the continuously variable controller is continuously output from the data storage unit, a variable output as in the related art can be obtained. When the "instantaneous output mode" is selected, the parameter values assigned to the continuously variable controller are not output continuously, and the contents stored in the data storage means are output when a signal is supplied from the trigger means. Therefore, no data is output during the operation of the continuously variable controller, so that the output value can be changed instantaneously instead of continuously.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing the configuration of an electronic keyboard instrument to which a data output device according to the present invention is applied. As shown in FIG. 1, a slider 1 as a continuously variable controller is provided at a rear portion of the keyboard. Are installed (four in the figure). By operating these sliders during a performance, the parameter values assigned to each slider, such as bend, tremolo, and pitch, can be continuously switched. A mode switch 3 is provided near the side of the slider 1 so that the switch 3 can switch between a continuous output mode and an instantaneous output mode. Further, a trigger switch 2 is provided in the vicinity of each slider 1, and an output trigger in the instantaneous output mode can be given by operating the switch 2 as described later.

FIG. 2 is a block diagram showing the configuration of one embodiment of a data output device according to the present invention. As shown in FIG. 2, a slider 1, a trigger switch 2, a mode changeover switch 3, a data storage unit 4, a data output unit 5,
And a trigger circuit 6. Slider 1
Is connected to the data storage unit 4, and the current setting value of the parameter assigned to the slider 1 is stored. When the parameter value is changed by operating the slider 1, the stored content is updated accordingly.

The data output unit 5 includes a mode changeover switch 3
When the continuous output mode is set, the data stored in the data storage unit 4 is output to the subsequent stage as it is. On the other hand, when the instantaneous output mode is set by the mode switch 3, the trigger circuit When the trigger signal from 6 is given, the data stored in the data storage unit 4 is output.

Next, the operation of this embodiment will be described with reference to the flowcharts shown in FIGS. FIG.
Is a flowchart showing a procedure for writing data to the data storage unit 3. As shown in the figure, first, the current values of the parameters assigned to the slider 1 are stored and saved in the data storage unit 4 ( Step ST1). If there is no slider operation (N in step ST2)
O), the data stored in the data storage unit 4 is held as it is until the next slider operation occurs, and the slider 1
Occurs (YES in step ST2).
S), the data stored in the data storage unit 4 is rewritten with new data (step ST3).

As shown in the flowchart of FIG. 4, when the continuous output mode is set by the mode changeover switch 3 (step ST11), the data output section 5 is stored in the data storage section 4. The parameter value is output as it is (step ST14). On the other hand, when the instantaneous output mode is set, the trigger switch 2
Is turned on (YES in step ST12),
The data output unit 5 outputs the parameter values stored in the data storage unit 4 to the subsequent stage (step ST13).

When the parameter assigned to the slider 1 is set to "tone frequency" and the mode changeover switch 3 is set to "continuous output mode", after the keyboard 7 shown in FIG. Since the frequency is continuously changed by the operation, it is possible to produce a sound with a bend in the range of 200 cents, for example.

On the other hand, when the keyboard 7 is depressed with the mode changeover switch 3 set to the "instantaneous output mode", a pitch corresponding to the depressed key is produced, and the slider 1 is changed in this state. The output frequency does not change, and when the trigger switch 2 is pressed, the pitch at the set frequency at this time is generated. For example, the pitch is changed by 200 cents by operating the slider 1 while an arbitrary key 7 is pressed, and the pitch changed by 200 cents is output when the trigger switch 2 is pressed in this state. In other words, the operation is performed such that the pitch does not gradually change to 200 cents, but instantaneously changes by 200 cents.

When the parameter assigned to the slider 1 is set to "tone number" and a tone signal is transmitted from the electronic keyboard instrument to another electronic instrument using MIDI, the mode switch 3 is set to "continuous". When the output mode is set, the tone number gradually changes to reach the desired tone number, so that at the transmission destination electronic musical instrument, the tone present in the process of the change is generated for a short time. There are stripes. On the other hand, mode switch 3
Is set to the "instantaneous output mode", when switching from the currently set tone number to another tone number, the slider 1 is operated to turn on the trigger switch 2 when the desired tone number is reached. It is possible to instantaneously switch to a desired musical sound.

As described above, according to the present embodiment, by operating the mode changeover switch 3, the slider 1 can be arbitrarily selected from the continuous output mode and the instantaneous output mode. If the output mode is selected, the parameter value can be changed instantaneously, so that the degree of freedom of each operation during the performance can be greatly expanded.

In the above-described embodiment, the slider has been described as an example of the continuously variable controller. However, the present invention is not limited to this, and the same effect can be obtained by using a rotary controller. it can. In the above embodiment, the tone frequency and the tone number have been described as examples of the parameters assigned to the slider. However, it goes without saying that other parameters can be similarly applied.

Further, in the above-described embodiment, an example has been described in which the mode changeover switch 3 is independently installed. However, the mode changeover switch 3 may be shared with another existing switch, or the mode may be changed to the continuous output mode in the initial setting. The mode may be switched between the output mode. In the instantaneous output mode, an example in which the parameter value is output when the trigger switch 2 is pressed has been described. Conversely, the parameter value may be output when the trigger switch 2 is released.

[0021]

As described above, according to the data output device of the present invention, the output mode of the continuously variable controller such as the slider can be set to either the continuous output mode or the instantaneous output mode. , Set the "tone frequency" as a parameter to be assigned to the slider,
If the continuous output mode is used, it is possible to perform output with a bend effect, and if the instantaneous output mode is used, a playing method in which the frequency is changed instantaneously becomes possible. in this way,
Any mode can be selected according to the form of various performances, and the range of performances can be significantly expanded.
