Description

[Detailed Description of the Invention] This invention relates to the improvement of electronic organs, electronic pianos, and other various electronic musical instruments equipped with keyboards consisting of scale keys and operators such as tablets and slide switches. In particular, scale keys that are not used when playing a specific "yA (Shirabe)" song are configured to function as operators that can generate musical tones with a specific type of preset effect. By doing so, it is possible to easily add additional functions to even inexpensive electronic musical instruments with relatively few types of controls, and it also makes it possible to make effective use of the keyboard surface and make it more compact. and a keyboard-type electronic musical instrument with improved operability during performance.

Electronic musical instruments such as electronic organs that have a keyboard consisting of scale keys and operators such as tablets and slide switches are equipped with several octave scale keys (hereinafter simply referred to as keys).

FIG. 3 is a diagram showing an example of a keyboard surface of a conventional keyboard-type electronic musical instrument. In the drawing.

11 is a keyboard, 12 is a tablet group, 13 is a switch group,
14 indicates a slide switch for volume adjustment.

Conventional keyboard-type electronic musical instruments, such as electronic organs.

As shown in the top view in Fig. 3, 49 or 61
A keyboard 11 consisting of individual keys, a tablet group 12 for controlling volume, tone, etc., and a switch group 13 for switching power switches, rhythms such as tango, blues, etc.
and sound! An adjustment slide switch 14 is provided.

However, relatively low-priced electronic musical instruments do not have tablets for controlling volume, tone, etc., nor touch detection devices for obtaining key press speed information provided by these tablets.

Therefore, in the case of such keyboard-type electronic musical instruments, the number of songs that can be played is limited, and as a result,
Users will not be satisfied.

However, in a normal song, the type of key to be used is determined by the key, and unless it is a special song, there are keys that are not used in the performance.

Therefore, the present invention solves the above-mentioned disadvantages of conventional keyboard-type electronic musical instruments, and by reusing unused keys as operators, it is possible to add many functions with only a small number of operators. The purpose of the present invention is to provide a keyboard-type electronic musical instrument that enables the performance of a variety of musical pieces.

To this end, the present invention provides a method for generating musical tones corresponding to the playing operation of a specific type of scale key in a conventional keyboard-type electronic musical instrument equipped with a plurality of scale keys and operators such as a tablet. and a scale key switching means that makes it possible to generate a musical tone with a specific type of effect set in advance, and when the scale key switching means is in an on state,
Control is performed to generate musical tones to which a preset specific type of effect is applied based on input from the scale keys.

Next, II of this invention! Embodiments of the board-type electronic musical instrument will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram showing an embodiment of the main structure of a keyboard-type electronic musical instrument of the present invention. In the drawings, 1 is a key, 2 is a scale key switching means, 3 is an adjustment leg means, 4 is a scale switching function key 5 is a tablet, 6 is a tone control section, 7 is a pitch control section, 8 is a CPU, and 9 is a tablet. A sound source circuit, 10 a D/A converter, and 11 an audio system.

The type IIaIIl type electronic musical instrument of the present invention shown in FIG. The configuration is basically the same as that of a conventional keyboard-type electronic musical instrument.

The operating method and operation of the keyboard-type electronic musical instrument shown in FIG. 1 during performance will be explained in detail with reference to the flowchart shown in FIG. 2, which will be described later.

As already mentioned, the key to be used for a normal piece of music is determined by its ``key,'' and unless it is a special piece of music, there are keys that are not used in the performance.

Therefore, by inputting the "key" of the piece of music that is about to be played, it becomes possible to use unused keys as operators.

Types of controls (types of effects) include tone tablet, portamento effect (frequency control), pitch vent effect (frequency control), and vibrato effect (frequency control).
, performs the waff effect (control of frequency characteristics).

FIG. 2 is a flowchart showing the flow of processing when a specific type of key is used as an operator in the keyboard-type electronic musical instrument of the present invention shown in FIG. In the drawing, 8
1 to S7 indicate steps.

In the electronic musical instrument shown in FIG. 1, when the scale transfer function key 4 is pressed, this is detected in step S1. In this state, the user enters the scale key diversion mode and first presses the key of the scale that will not be used in the song to be played (unused 1).

In step S2, by inputting this unused key, which
Determine whether "key" is set.

When the "key" setting is completed, an instruction is given as to which type of control the unused key should be used for. The type of the operator is also specified using 'a1'. In this case, which scale key indicates which effect is determined in advance.

For example, scale C is a tone tablet, scale is a portamento effect, note FJE is a pitch bent effect, scale F is a vibrato effect, and scale G is a waff effect. By using a specific scale key, you can create different types of effects. instruct.

In step S3, the type of effect is input by such an operation.

On the other hand, if the scale conversion function key 4 has not been pressed, this is detected in step Sl, and the process proceeds to step S4, where it is determined whether or not the key has been pressed.

If the input is a key press, in step S5, the effect key (
It is determined whether or not an input (manipulator) is input, and if it is an input of an effect key, the process proceeds to step S6, and processing is performed to generate the instructed effect.

If the result of the determination in step S5 is that an effect key is not input, the process proceeds to step S7, and processing is performed to generate a musical tone of the scale corresponding to the pressed key.

In this way, in the keyboard-type electronic musical instrument of the present invention, scale keys that are not used depending on the "key" can be used as operators for imparting desired effects.

For example, in the case of "C major", 9A#, ~A#, are not used, so with the keyboard-shaped child instrument of this invention shown in Fig. 1, @A# is used by the operation shown in Fig. 2. #
, ~A#2 are used as operators for instructing vibrato effects, tone tablets, portamento effects, pitch vent effects, etc.

Furthermore, in the case of a model that does not have a touch detection device, it can also be used as an operator for inputting information for controlling volume and tone, that is, key pressing speed information.

In this case, you can "tune" the keys assigned to these controls by lighting them with, for example, light-emitting diodes.
It is also possible to learn key strings corresponding to .

Note that in the above embodiment, a specific type of key, for example, IA
A case has been described in which L to A#2 all have the same effect (functioning as the same operator), such as a vibrato effect, for example, a case where they are operators that provide a vibrato effect.

However, it is also possible for IIA # and ~A#2 to be different types of operators, and it is not necessarily the case that keys of a specific type (for example, keys A#6 to A#2) all have the same function. It is not necessary to correspond to the commanding operator. That is, the key A# can be used to give a vibrato effect, and the key A#5 can be used to give a different effect to each scale of faA#6 to A#2, like a tone tablet. It goes without saying that this includes these cases as well.

Furthermore, the keyboard-type electronic musical instrument of the present invention can have its additional functions in conjunction with the original controls; in this case, the performer can select whichever key is easier to touch while playing the piece of music. According to the keyboard-type electronic musical instrument of the present invention, the number of operators such as tablets is small and additional functions are limited. Many functions can be added to electronic musical instruments, making it possible to perform in a wide variety of ways.

In addition, in the case of conventional keyboard-type electronic musical instruments that have many tablets, etc., by using the scale keys as operators,
Since the total number of operators can be reduced, many excellent effects can be obtained, such as miniaturization.
