Description

[Detailed Description of the Invention] The present invention relates to a tone color display device for a tone color switch in an electronic musical instrument such as an electronic organ.

Conventionally, a musical tone signal generated by pressing a key on a keyboard is supplied to a speaker via a tone filter circuit selected by a tone color switch, and a musical tone of a desired tone is emitted.For example, in an electronic organ, a plurality of tones are displayed on the panel surface. Generally, tablet switches were arranged in a fixed order.

For this reason, it had the disadvantage that it did not suit the player's taste and was difficult to play.

The purpose of the present invention is to eliminate this drawback, and the musical tone signal generated by pressing a key on the keyboard 1 is filtered through the timbre filter circuits 3-1...3 selected by the timbre switches 2-1...2-5. - 10, the electronic musical instrument supplies signals to the speaker 4 via a plurality of timbre name characters, etc. signal generators 5-1...5-10;
A plurality of display devices 6-1...6-5 provided on or near the tone color switches 2-1...2-5 and a plurality of tone color switches 2-1...2-5 are connected to respective predetermined tone color filter circuits 3-. 1...3-10 control terminal 3
a-1...3a-10 and a tone color name character signal generation device 5-1 corresponding to the tone color;
A plurality of tone color editing switches 7a-1...5-10 are selectively connected to display devices 6-1...6-5 provided on or near the tone color switches 2-1...2-5.
7a-10, 7b-1...7b-10, 7c-1...
7c-10,7d-1...7d-10,7e-1...
7e-10.

In the circuit shown in the first diagram, the timbre filter circuit 3
For example, timbre filter circuits for violin, flute, oboe, trumpet, and horn are provided as timbre filter circuits 3-1...3-5. 1... A signal generating device for tone color name letters, etc. was provided in the same order as in 3-5. Tone editing switch 7a-1...
7e-5 each consists of two interlocking switch elements, of which one switch element of 7a-1...7a-5 is connected to each tone filter circuit 3-1.
...3-5, and intervenes between the control terminals 3a-1...3a-5 and the tone switch 2-1, and the other switch elements are the display device 6-1 and the tone color name character signal generator 5-1...5-, respectively. I intervened during the 5th period. Similarly, 7b-
1...7b-5, 7c-1...7c-5, 7d-1...
The switch elements 7d-5, 7e-1...7e-5 are also connected between the tone switches 2-2...2-5 and the tone filter circuits 3-1...3-5, and the display devices 6-2...6-
5 and the tone color name character signal generator 5-1...5-5.

The display devices 6-1...6-5 may be placed near the tone tablet switches 2-1...2-5 provided on the clappers 8 of the electronic musical instrument as shown in FIG.
As shown in the figure, the tone tablet switch 2-1...
It may be provided above 2-5.

The display devices 6-2...6-5 use electronic displays such as dot matrix or liquid crystal as shown in FIG. Therefore, in FIG. 1, the display devices 6-1...6-5 and the tone color name character signal generation device 5
Although the signal paths and switch elements between -1...5 and -5 are shown as one line and one switch element, in reality they are multiple lines and switch elements.

The tone color name, character, etc. signal generating devices 5-1...5-5 are capable of generating signals such as pictographs, symbols, etc. in addition to characters.

For example, as shown in FIG. 4, the tone editing switches 7a-1...7e-5 are arranged in columns for each tone of violin, flute, etc., on a panel 9 provided on a clapboard of an electronic musical instrument, etc., and tone color tablet switches 2-1...2 are provided. −
Install them in rows every 5.

In FIG. 1, 10 is a tone generator circuit, and 11 is a musical tone signal circuit.

Thus, now the tone switch shown in Figure 2~2
-1...2-5 in the order of flute, trumpet, horn, oboe, and violin, the tone editing switches 7a-2, 7b-4, 7c-5, 7d-3, 7e
Operate -1. As a result, in the circuit shown in Figure 1,
The timbre switch 2-1 is connected to the control terminal 3a-2 of the flute timbre filter circuit 3-2, and the flute timbre name character signal generator 5-2.
is connected to the display device 6-1. Therefore, the characters FLUT (flute) are displayed on the display device 6-1, and when the tone color switch 2-1 is closed, the tone color filter circuit 3-2 for the flute is selected. Similarly, TRUP (trumpet), HORN (horn), OBOE (oboe), and VIOL (violin) are displayed on the display devices 6-2...6-5. The adjacent tone switches 2-2...2-5 are control terminals 3a-4, 3a-5, 3a-3, 3a of the tone filter circuits 3-4, 3-5, 3-3, 3-1 for the displayed tone. -1 respectively.

The circuit configuration shown in FIG. 1 is not limited to the timbre switch of the upper keyboard, but can also be used for the timbre switch of the lower keyboard and foot keyboard.

In this case, the keyboard tone switches are arranged in the order of foot keyboard tone switch 12, upper keyboard tone switch 13, and lower keyboard tone switch 14 as shown in FIG. 5, but this arrangement can be changed freely. It may be configured as follows.

6A and 6B show schematic illustrations of other embodiments of the present invention. This has a greater number of tone filter circuits than tone switches, and allows the performer to select the type of tone necessary for the performance and arrange the tone switches in the order of the tones he or she deems necessary. be.

In FIG. 6A, 3-1...3-10 are wood bass, electric bass, tuba,
A timbre filter circuit for trombone, bassoon, clarinet, bourdon, flute 16', flute 8' and strings, etc. 5-1...5-10 is a signal generating device for timbre name letters arranged in the same order as the above timbres, The timbre editing switch 7a-1, for example, consists of two interlocking switch elements as shown in FIG. 6B, one switch element being the timbre switch 2.
-1 and the control terminal 3a- of the tone filter circuit 3-1.
1, and the other switch elements are the display 6-1.
and the tone color name character signal generator 5-1. The indicators 6-1...6-5 are respectively provided above or near the tone switches 2-1...2-5.

Thus, now, in FIG. 6A, when the tone editing switches 7a-1, 7b-3, 7c-4, 7d-9 and 7e-10 are closed, the displays 6-1...6-5
displays the letters Utsudo bass, Teuba, trombone, flute 8', string, etc., and selects the tone switch 2-1 corresponding to the display device on which this display appears.
...2-5 are connected to tone filter circuits 3-1, 3-3, 3-4, 3-9, and 3-10 corresponding to the display.

Therefore, the timbre switch can be assembled in an appropriate timbre arrangement for the performer to select the desired type of timbre from among a large number of timbres, making it possible to reduce the panel surface of the electronic musical instrument and making it possible to select the desired timbre. Simple and easy to operate.

In addition to the above embodiments, the computer's CPU
By connecting a timbre switch, an editing switch, a display device, and a timbre switch signal generator to a timbre switch signal generator, and connecting the timbre switch signal generator to a timbre filter circuit of an electronic instrument, the circuit configuration is simple and the timbre switches can be freely arranged. available.

In this way, according to the present invention, the player can determine the arrangement of the tone switches to suit the player's preference or the piece of music he or she is playing, and the arrangement can be determined by a display placed above or near the tone switches. By making it possible to check the instrument, it becomes the player's own instrument and has the effect of making it easier to play.
