Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for controlling a chord generator, and more particularly, to a device for controlling a chord generator, and more particularly to a device for controlling a chord generating device, and more particularly, for controlling a chord generator in a preselected combination of different chords in an organ having an automatic first note circuit. This invention relates to a control device for playing different types of music.

Background of the Invention Many performers who perform solo in front of an audience find themselves intimidated by the inability of their instruments to produce the necessary richness and variety of sound during their performance, no matter how well they play. I am aware that there is. Therefore, it is customary for noro players to use rhythm boxes or other wasatsu generators to provide accompaniment to their instruments.

'10; A child organ is suitable for providing the necessary accompaniment, but the instrument's fairly complex keyboard and pedals usually require the assistance of an assistant.

For this reason, it has traditionally been considered impossible for noto players who play their own instruments to use the chord section of the organ.

Accordingly, there is a need for a relatively simple and easily operable control device that serves such purposes. 3. Description of the Prior Art A number of US patents have been granted in the art of this invention. .

Among them is U.S. Pat. No. 3,420,940 to Glass et al., which relates to automatic performance devices for musical instruments such as organs. U.S. Patent No. 2.761 by Kocbl
, No. 344 relates to a piano as an example of a device for generating and converting drowsy sounds. U.S. Patent No. 6,839,592 by Freeman discloses a device that automatically extracts and plays a bass note from an accompaniment chord, and that uses a control pedal to play a sustained bass note. It is related to. U.S. Pat. No. 3,178,501 to Evans is directed to a foot-operated control device for varying the volume of a low frequency signal transmitted from an electric guitar to an amplifier.

This relates to a device that changes the melody pattern of an organ. Indeed, U.S. Pat. No. 5,084,584 to Iorio is directed to a combination of musical instruments that can be controlled in part by a pair of foot-operated phonological control devices.

However, none of these prior art discloses a device for controlling the automatic chord section of an electronic organ, which is the object of the present invention.

SUMMARY OF THE INVENTION The present invention aims to provide a control device for playing several different combinations of preselected chord sections of a turtle organ;
The device of the invention comprises a support housing a number of suitably arranged chord switches spaced apart from each other;
The switch is opened and closed by the player, for example, by the movement of the player's feet.

The number of chord switches is smaller than the number of chords played in one chord section of the organo, and is, for example, 3 to 7. These switches are connected to a multi-stage selection switch that can be operated simultaneously, and by setting this selection switch and operating the chord switch, Different combinations of preselected chord parts can be played individually.

This device can accommodate one of the performer's legs appropriately:
This is a remote control device with a support body shaped like this. Preferably, this device has a plurality of chord switches spaced apart from each other so that the player can operate them individually by appropriately moving his or her feet.

In the explanatory diagrams of the embodiments, the reference numeral (10) indicates the entire remote control device according to the present invention.

In Fig. 1, this device (1()) is connected to an electronic organ (12) with a flexible tolerance circle.This special chord organ (12) is connected to an ordinary keyboard. It has a q-shape and has one chord part on the left side.

Using an electric key or something similar forming the chord section +151, the player can play the automatic chord section provided in the organ to which the invention is directed. Moreover, pressing a single switch is enough to create a complete chord.

The remote control device (10) according to the invention is foot-operated and allows a solo guitar player to play his instrument, for example, while standing at some distance from the organ, or while sitting. You can also play this [Wa7ko organ] by making full use of the automatic chord section.

The remote control device (10) is preferably equipped with a number of chord keys, or the equivalent of a pedal. For this purpose, this device is equipped with a box-shaped support
This support QO) has a closed back part (21) and a front part 122) which is open at the top.

) is attached to the bottom plate by using the setscrew (26C) inserted into the screw (26B).

Switches (1) to (7) are mounted on the wall of the support (a). These switches are connected to the drowsiness circuit so that when closed, an organ chord is played.

In Figure 2, the switch (1) is in the normally open state.
- (7) are shown, and the dotted line C321 represents the outline of the player's foot.

The switch (1) is located on the bottom plate (24) and is usually hidden under the heel. The switches (2) and (6) are mounted on the corresponding side plates (26), are slightly spaced upward from the bottom plate (24), and are located slightly behind the switch (1). There is. Place the switch (5) on the opposite side plate (26) (71).
It is also slightly spaced upward from the sole plate (24), and has some distance from both sides of the foot to the rear of the toes.

The switch (4) is attached to the intermediate wall (27) well above the sole plate (24), and is far enough away that the toe does not hit the switch when the sole of the shoe is placed on the pad (25), and The switch (1) is located in the center under the heel. The switch (61fd) is attached to the intermediate wall (2n) slightly below the switch (4), and is located in a place where the tip of the toe does not hit when the heel is on the switch (1).

As best shown in Figure 6, the switch (1) has a bottom plate (24

) and the switch (6), a small compression spring (
96) has been taken into account, and it is a combination of the pedal (92) and the plunger.

Therefore, when the foot approaches the pedal (92) and moves the foot forward, the plunger (90) is depressed and the switch (6) can be operated.

Switches (1) to (7) are designed to have exactly the same A motion as some of the chord keys or pedals attached to the organ (12).

This neck electronic organ usually has 12 playing chord sections. However, the remote control device (10) described here
In the embodiment, only seven chord switches are provided.

A suitable selection switch (1
00) is provided. This selection switch (100)
The switch may be a conventional slide-controlled printed circuit board type, but a simple mechanical switch is preferred.

As shown in FIG. 1 and detailed in FIGS. 5 and 6, the selection switch (100) is attached to the earthen wall (102) of the rear part (21), and its main sand part is contained within the body.

As shown in FIG. 6, the switch (100)
o2) is attached to the bottom surface of the maggot knob (10
). A vertical shaft (105) is pivoted within the maggot knob, and one end of this vertical shaft (105) extends through a hole (106) in the second wall (102);
It supports the knob (107).

In this housing there is provided an annular plate (1 (39)) corresponding to each chord switch. This horizontal plate is spaced vertically along the vertical axis (105) and This vertical axis is freely rotatable within the annular plate (io9). Each annular plate (109) has twelve contact portions (112) in the circumferential direction. It is arranged.

An arm (114) is secured to this vertical axis adjacent each plate. This arm (114) has a knob (107).
) is provided with a contact (i 1s) that comes into contact with the contact portion (112) at a - location each time the vertical shaft (105) is rotated.

This X selection switch (ioo) is of normal design. Therefore, the internal switch device and its associated electrical connections will be described in detail later in the circuit related to the selection switch, and will not be described in detail here.

Next, FIG. 5 will be explained in detail.

The knob (107) is attached to a circular fledge (117). This flange (117) has S 1 + 82 so as to correspond to the chord switches (1) to (7).
Heading arrows labeled as tl are arranged in a circumferential manner.

An annular band (118) is fixed to the outer surface of the earthen wall (102) so as to surround the knob (107). In this annular zone, the 12 chords that are normally played by the electronic organ (12) are clearly displayed.

In FIG. 7, the electronic organ (12) is connected by a simple flexible wire (11).

This wire connects the remote control device f & 6t (circuit for 10)
124).

The circuit (124) is shown in detail in FIG. 8, and consists of four wires (11j is 15 wires).

The leftmost wire in the group of wires leading to the selection switch (ioo) is a common ground wire that reaches 7 at each switch (1)-(7).

The other 12 lines to the right of the ground wire each correspond to the special O L1 note of the organ, and from left to right in Figure 8 are A, #2, 13, C, Car, 1), 1#-1
They are displayed as E, F, π:, G, and IJ2.

Chord switch (1) is the first switch in this device, and the remaining chord switches (2) to (7) are:
All are related sequentially to the first switch, as described below.

Further, six lines are shown on the left side of the ground line in FIG. These three lines are connected to a switch (130). This switch (130) is attached to the support frame at a location convenient for the player to operate.

The switch (130) is a push button (131) (13
2), and the latter (132) is equipped with two operation parts. This (with the switch inside, the organ 02
) can be played by means of the device ^''j (10).

Typically, such chords are played by the pedals shown on the front of the organ in FIG. 1, but any pedal can be played.

A guitar player or other performer who wishes to add chordal accompaniment to a solo piece he is playing may 'switch on the electronic organ (12) and then use the remote control device (12).
10 and prepare for performance by connecting the circuit (124) to the automatic chord circuit (120).

The performer comes to this remote control device (10) and decides which piece he wants to play.The organ has 12 chords available to the performer, but for experienced musicians,
Even for special pieces, chords of six chords or more are usually sufficient.

Next, the performer selects a special series of chords that he/she wishes to play and performs them using the selection switch (100).

With the switch (1), the knob (107) of the chord selection switch (to select to play C1)
As shown in the figure, move the SI to the position where it matches the chord (C). Then, the performer can understand the following by just glancing at the selection switch display board.

That is, switch (2) plays the chord CG+ (A, switch (3) plays the chord (Fl), switch (4) plays the +-i chord (
1)), switch (51U chord, A), switch (
6) is pre-selected to match the chord (Ju), and the switch (7) is suitable for special chords that are not included in the normal scale consisting of the oto (Bl) or fifths. The other chord parts will be played automatically.

A selection switch (134) is provided for selecting the chord to be played by switch (7).

With that one point of contact, you can play a scale of fifths. However, at other contacts, by properly actuating the multi-stage switch, the switch (the first
can play sounds.

The predetermination of the chord part is determined by seven annular plates (109) whose associated contacts (112) are wired in the selection switch (100).

The particular sequence of chords shown here was chosen as the most light-permeable switch arrangement for this remote control device.

By adding a selection switch (154), the performer can select which chord to use switch (7) for. In some cases, the selection switch
It may be left set to the normal sequence of the fifth scale. Of course, here, the key (C) comes at the first switch, so switch (71it)
(ri) Become flat.

In this way, the performer can play solo pieces and operate the organ without the help of other people.
A performer who plays at least seven chords must over-insert his foot into the apparatus shown in Figure 1 and play the chord (C).
), all you have to do is turn your heel down and open/close the switch (1).

The chord parts fG) and (F) are played by moving the heel of the foot left and right and closing the switches (2) and (6).

The chord part 廄) and (B) flat are played by moving the part of the foot near the toe laterally and closing switches (5) and (7).

To play chords (D) and (E), raise your toe and press switch (4), or press toe 1
11 and operate switches (4) and (6).

The next song requires another sequence of up to seven chords, and the player presses the first switch (1) to the 11th chord.
Assuming that the performer has decided on the "key combination" of the note (Gl), the performer turns the selection switch (100) so that the SI becomes the chord (0
) and take it to a place where it matches. Remaining chord switch (2
) to (7) are the respective chords (D), fc), (
A).

(E), (13) and fF) are automatically connected by the selection switch to play.

Next, turn the knob (107) to remove the flange' (117).
The chord (DJ) on the band (118) is
, the first switch (1) closes and the chord (I
)) is played. At this time, the remaining switches (2) to (
7) are the chords (AI, (Ol, 1jil,
(+31. You will play (r゛) Nyaab and (C).

Using the aforementioned control device t(IF), the performer can select the sequence of seven chords needed to play by means of the chord switch. A skilled performer can use all seven chord parts as accompaniment. On the other hand, inexperienced performers may use fewer chords.

For example, only six chord parts may be used as accompaniment.

In such a case, the control device may be constructed so that it can be more easily connected to the selection switch and used only for the six chord control switches.

This control device (IQ) is preferably one that can be controlled remotely, but it goes without saying that it can be incorporated into an electric chestnut machine, such as an organ having an automatic chord circuit, if necessary.

The chord switch is smaller than the chord section available on an organ, but according to this device, it can switch the o() note to be played.
Depending on the arrangement of the switch sections, selection can be made in a predetermined sequence.

The pre-sequence of the chord parts is based on the scale of fifths and is predetermined by one selection switch. This switch can automatically select chord parts regardless of the position of the switch around the foot in the same state.

There are no pedals to confuse the operator, and the black, basic two-chord structure that all performers are familiar with is the fifth scale. The selection switch is wired based on this scale of 5ths, and by simply dialing the primary key on the selection switch, this wiring is done automatically for all keys, and the rest of the actuation is done by the switch. It will be done. Therefore, the player does not need to have any knowledge about the wiring connections.

Even if you are a relatively inexperienced musician, if there is an inventive device, you can perform just like a professional without years of practice.

Switches (1) to (7) and the arrangement on the selection switch (are arranged so that minor scale chords related to all keys are played by the same switch, e.g. switch (5) unrelated to the key -'(
The f-movement and the off-chord (oN-chord) are almost always a switch (4).

Therefore, all performers can immediately visually check the performance, and regardless of which key they play, they can play even the most complex pieces by simply memorizing a simple arrangement of chord switches. be able to.

The basic melody of a piece must be the same in every performance, but the performer cannot sing or play in a key in which the score has already been played. Therefore, I usually first choose a key that suits my voice or one that makes it easy to play the song.

The performer simply selects a key, and tries to pitch or lower the note? The easiest key is f4, which is also one key.
can be found quickly. Dimension/ζ, its chord part is
Depending on the movement of the foot, it is automatically preselected at the first position and displayed on the selection switch. Therefore, the player 1' can automatically know whether to play the O L1 note with another instrument, such as a handheld instrument, for example.

It takes less than a second for the performer to select the multi-stage selection switch and then start playing. Therefore, switching from one song to another can be done quickly and easily. Therefore, since the time between songs is short, even if the performer sets many different switches to one, it will not irritate the audience.

The switch (100) is a multi-contact multi-stage switch, that is, a plurality of switches arranged in a multi-stage manner so that they can be operated simultaneously. The illustrated switch is a rotary mechanical type switch, but it is clear that other types can be used to achieve the same result. For example, it may be a slide switch or a combined switch.
