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 applying variable modulation, to 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 when the performer changes his/her hand from side to side during a performance, However, in order to maintain the same direction of change in the effect applied during performance, the controller must be operated in the opposite direction, which may cause confusion in the performance, and has been pointed out to be inconvenient in operation. was.

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 means for selecting whether or not to change the operation data, and the operation data changing means changes the acoustic effect represented by the operation data of the operator to an inverse characteristic.

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 using, for example, a manual switch, the acoustic effect represented by the operation data of the operator is changed to have an inverse characteristic. The direction in which the effect changes relative to the child's operation direction is opposite to normal, and if you move the control in the direction where the effect used to be large, the effect will become smaller, and if you move the control in the direction where the effect used to be small. If you move it, the effect will become stronger.

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 by a combination of a specific key on the keyboard and a power switch, the power switch can be pressed while pressing down a specific key. The selection means may be activated by the input, or other special operating mechanisms may be provided.

The selection means reverses the change direction of the operation data when desired with respect to the operation direction of the operator,
For example, if the control output is a digital code signal, the operation data changing means may include a data converter that reverses the change in code content relative to the control position, or may mechanically control the movement of the knob. It may also include a mechanism for transmitting the reverse transmission.

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 which receives information output from the key detection circuit 2 and allocates 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, Japanese Patent Application Laid-Open No. 49-84215,
Those disclosed in Japanese Patent Publications No. 49-84216, No. 49-130213, and Japanese Patent Publication No. 59-41591 can be used, and will not be specifically described here.

In FIG. 1, this synthesizer includes not only the main parts 1 to 5, their power source 6, and power switch 7, but also a musical tone forming circuit 4 which is provided with a control signal to apply the aforementioned acoustic effects to the musical tone signal. Operating device 1 according to the present invention for adjusting the amount of application
It is equipped with 0.

That is, the operating device 10 includes an operating element 11 such as a pitch bend wheel or a modulation wheel.
By operating the operator 11, the pitch of the musical tone of the musical tone forming circuit 4 and the modulation effect can be changed. The position change due to the operation of the operator 11 is detected electrically 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 13 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 "0000" at position 0 is input, the output is "1000", which is the same as the code content at position 15, and at position 2, when "0001" is input, the code content at position 14 is output. Outputs the same ``1001'' as ``1001'', and then converts and outputs the code in the opposite position in the same way.

The output of the operator detection section 12 is applied as it is to one input terminal of the selector 14 on the one hand, and is converted via the data converter 13 and then applied to the other input terminal of the selector 14 on the other hand. The selector 14 selects a signal applied to one of these input terminals and passes it as a control signal to the musical tone forming circuit 4, and the selection switching operation is performed in conjunction with turning on the power switch 7. There is.

In other words, when the power switch 7 is turned on, the differentiating circuit 15
The detection pulse from the differential circuit 15 triggers the flip-flop 17 via the gate circuit 16, which is open only when a specific key on the keyboard 1 is pressed down, and the output of the flip-flop 17 triggers the selector 14. Switch. In this circuit configuration,
When the power switch 7 is turned on without pressing down the specific key, the selector 14 transmits the output of the operator detection section 12 as it is to the musical tone forming circuit 4; 7, the selector 14 transmits the signal converted by the data converter 13 to the tone forming circuit 4.

Figure 4 shows an example of a pitch bend wheel, and Figure 5 shows an example of a modulation wheel. Turning the knob toward the other end will change the effect by increasing the pitch or increasing the amount of modulation.
Conversely, when the wheel is turned from the front to the front, the pitch decreases, or the effect of modulation becomes weaker. This is the normal usage state, but if you turn on the power switch 7 while holding down a specific key, the direction of change in effect relative to the rotation direction 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 when turned toward you, the pitch increases or the modulation becomes 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 operating element. When using a synthesizer that can be installed on a desk as usual, the effect changes in the normal direction, and when playing standing, the effect changes in the opposite direction with the same control direction, making it easier for the performer to Even if the instrument is in the opposite position than usual, you can always apply the same change direction effect by operating your fingers in the same direction without being conscious of it, eliminating operational inconvenience. It is something.
