Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operating device that adjusts the application of acoustic effects to musical tones of an electronic musical instrument.

[Prior Art] Conventionally, operating devices have been known that impart acoustic effects, such as increasing/decreasing pitch or variable modulation, to the musical sounds of electronic musical instruments. The controls of this type of control device are placed near the performance control section of the electronic musical instrument for each assigned function (effect), and the direction of the control and the direction in which the effect changes are fixed in a certain relationship. has been done.

[Problems to be Solved by the Invention] According to the conventional operating device, when a performer holds the installed electronic musical instrument in his/her hand for the convenience of playing, or changes his/her hand from side to side during a performance, In order to make the effect change in the same direction as before during performance, the controller must be operated in the opposite direction, which may cause confusion in the performance, and it has been pointed out that this is inconvenient in operation. .

The present invention aims to provide an operating device for an electronic musical instrument that does not cause the above-mentioned operational inconveniences.

[Means for Solving Problems] In order to solve the above-mentioned problems, the operating device for an electronic musical instrument of the present invention includes an operator that outputs operation data that changes depending on the direction of operation, and a controller that outputs operation data that changes depending on the direction of operation, and a In addition to an effect imparting means for imparting an acoustic effect according to the operation data, an operation data changing means for changing the operation data represented by the operator, and a selection for selecting whether or not to change the operation data. and means for changing the acoustic effect represented by the operation data of the operator to an inverse characteristic by the operation data changing means.

The operator is, for example, a directional controller that has a slide knob or a rotary knob that is placed near the playing section of the electronic musical instrument, and in normal use, moving it in one direction increases the acoustic effect. This means that if you move it in the opposite direction, the effect will be smaller.

[Function] In the operating device for an electronic musical instrument of the present invention, by activating the selection means, for example, by a manual switch, the acoustic effect represented by the operating data of the operating element is changed to the opposite characteristic. The direction in which the effect changes relative to the direction of operation is opposite to normal; moving the control in the direction where the effect used to be large will cause the effect to become smaller, and moving the control in the direction where the effect used to be small. On the contrary, the effect becomes greater.

The manner in which the effect changes is not limited to changes in magnitude, length, increase/decrease, slowing, etc., but may also be a transition from one effect to another.

Furthermore, the operation of the selection means can be controlled using various devices other than the manual switch described above, and the power switch can be turned on while pressing down a specific key by combining a specific key on the keyboard with the power switch. The selection means may be activated by the input, or other special operating mechanisms may be provided.

The selection means is for reversing the changing direction of the operation data when desired with respect to the operation direction of the operator, and the operation data changing means is for changing the code content for the operator position, for example, if the operator output is a digital code signal. It may include a data converter to reverse the change or alternatively include a mechanism to mechanically reverse the movement of the knob.

Examples are given below for a better understanding of the invention.

[Embodiment] FIG. 1 shows an embodiment in which the present invention is applied to a synthesizer having a keyboard 1 as an electronic musical instrument.

In FIG. 1, a keyboard 1, a key press detection circuit 2 that detects the ON or OFF operation of the key switch of each key arranged on the keyboard 1 and outputs information identifying the pressed key, and a sound generation assignment circuit 3 that receives information output from the key press detection circuit 2 and assigns the sound of the key represented by the information to a channel corresponding to the maximum number of simultaneous sounds (for example, 12 notes); and a key given from the sound generation assignment circuit 3; The main part of the synthesizer is composed of a musical tone forming circuit 4 that outputs a musical tone signal of a desired tone according to the code output, and a sound system 5 that converts the musical tone signal output of the musical tone forming circuit 4 into an acoustic signal. Regarding each circuit device of this main part, for example, JP-A-49-84215, JP-A-49-84218,
Those disclosed in Japanese Patent Publications No. 49-130213 and Japanese Patent Publication No. 59-41591 can be used, and will not be described in detail here.

In FIG. 1, this synthesizer is shown in the main parts (1 to 1).
5) In addition to the power source 6 and the power switch 7, there is also an operating device according to the present invention for controlling the application of the above-mentioned acoustic effects to the musical tone signal by applying a control signal to the musical tone forming circuit 4. It is equipped with 10.

That is, the operating device 10 has an operator 11 such as a pitch bend wheel or a modulation wheel, and can change the pitch of the musical tone of the musical tone forming circuit 4 or change the modulation effect by operating the operator 11. .

A position change caused by the operation of the operator 11 is electrically detected by the operator detector 12 and output as a digital code signal such as a truth table as shown in FIG. 2 or 3, for example. Note that in FIGS. 2 and 3, hatched portions indicate logic level "1", and unhatched sections indicate logic level "0".

When the data converter 3 receives the digital code signal, it converts it into a code corresponding to the opposite code with respect to the position and outputs it.

For example, in Figure 2, when the code signal r O00, OJ at position 0 is input, position 1
It produces the same output of rloooJ as the code content in 5, and in position 2, the input of rooolJ causes position 1.
It outputs "1001", which is the same as the code content in step 4, and similarly converts and outputs the code in the opposite position.

On the other hand, the output of the operator detection section 12 is directly transmitted to the selector 1.
4 to one input of the data converter 1 and the other to the data converter 1.
3 and then applied to the other input terminal of the selector 14. The selector 14 selects a signal applied to one of these input terminals and passes it to the tone forming circuit 4 as a control signal, and the selection switching operation is performed in conjunction with turning on the power switch 7. There is.

That is, the turning on of the power switch 7 is detected by the differentiating circuit 15, and the detection pulse from the differentiating circuit 15 drives the flip-flop 17 via the gate circuit 16, which is open only when a specific key on the keyboard 1 is pressed down. trigger, and the selector 14 is switched by the output of the flip-flop 17. In this circuit configuration, the power switch 7 is turned off without pressing down the specific key.
When the switch is turned on, the selector 14 transmits the output of the operator detector 12 as it is to the tone forming circuit 4. On the other hand, when the power switch 7 is turned on while holding down the specific key, the selector 14 transmits the output of the operator detector 12 to the musical tone forming circuit 4. The converted signal is transmitted to the tone forming circuit 4 at step 13.

Figure 4 shows an example of a pitch bend wheel, and Figure 5 shows an example of a modulation wheel. For example, if you start playing by simply turning on the power switch 7, turn the wheel from front to back when facing the operator. This gives an effect change in which the pitch goes up, or the modulation becomes stronger, and when the wheel is turned from the front to the front, the pitch decreases, or the modulation becomes weaker. is given. It is in normal use, but if you turn on the power switch 7 while holding down a specific key, the direction of change in effect with respect to the direction of rotation of this wheel will be reversed, and if you turn it toward the other side, the pitch will decrease or the modulation will change. becomes weaker, and turning it toward you will cause the pitch to rise or the modulation to be stronger.

[Effects of the Invention] As described above, the operating device for an electronic musical instrument of the present invention is provided with a selection means for reversing the change direction of the acoustic effect with respect to the operating direction of the operator. When using a synthesizer or synthesizer that can be used normally on a desk, the effect changes in the normal direction, and in the case of bean odor, the effect changes in the opposite direction with the same control direction. This eliminates operational inconvenience, as even if the user is in the opposite position relative to the instrument, they can always apply the same change direction effect by operating their fingers in the same direction without being aware of it. It is something that will be done.
