Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke performance stringed instrument in which a MIDI file player is built into a stringed instrument such as an electric guitar, and the stringed instrument can be played by a player who is emitted from its speaker.

[0002]

2. Description of the Related Art It has been known that an electric guitar has a body portion in which an amplifier, a speaker, an executor or the like is built in, and the performance sound can be directly output from the built-in speaker. In addition, MIDI (Musical I
nstrument Digital Interface
e) A computer music system is known in which a sound source is driven by a personal computer and instrument sounds having various tones can be output to an audio device. In that system, an external storage device such as a floppy disk drive connected to the computer is known. To MIDI
By reading and writing song data such as files, desired music can be played, stored and edited. It is also well known that song data of karaoke is distributed to this computer music system through a telephone line and used as communication karaoke.

However, since the above-mentioned conventional computer musical system is large in size as a whole and is not easy to move, a minus one performance (that is, a part of the stringed musical instrument) is performed by using a portable stringed instrument such as a guitar. However, there is a problem in that the advantage of a stringed instrument that is excellent in portability such as a guitar is lost because it can be done only in the place where the system is installed, even if an attempt is made to play an accompaniment with an instrument other than a computer.

Further, the electric guitar has conventionally been capable of variously processing and expressing the original tone color by simultaneously using effectors such as reverb, chorus, distortion, delay, etc. When performing an ensemble with the Gic system, it is difficult to adjust the balance between the effector set on the computer side and the effector set on the electric guitar side, and it is difficult to obtain a desired tone image.

[0005]

SUMMARY OF THE INVENTION Therefore, according to the present invention, all the devices necessary for playing a MIDI file are incorporated in the body of the stringed instrument so that the portability of the stringed instrument is not impaired, and the effectors are adjusted. It is an attempt to make it easy.

[0006]

To this end, the karaoke playing stringed instrument of the present invention comprises a MIDI sound source, a microcomputer for driving the MIDI sound source, an external storage device capable of reading a MIDI file, and a vibration of the string. A pickup for converting into a signal, an AD converter for converting an audio signal obtained from the pickup into a digital signal, a mixer with a digital effector for modulating and synthesizing the output of the MIDI sound source and the output of the AD converter, It is characterized in that a DA converter for analog-converting the output signal of the mixer and an amplifier and a speaker for amplifying the output signal of the DA converter are built in the body of the stringed instrument.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an electric guitar will be described as an example of an embodiment of the present invention with reference to the drawings. In the electric guitar shown in FIG. 1, the body 1 is provided with a pickup 3 for converting the vibration of the strings 2 into an audio signal, and an output terminal 4 for externally outputting the audio signal of the pickup 3 is provided as usual. A main unit 5, a control unit 6, a magneto-optical disk drive 7, a battery box 8 and a speaker 9 are provided in the body 1. FIG. 2 is a block diagram showing the relationship between these devices. Main unit 5
Is a WAVEROM in which PCM sound source data is written
A MIDI sound source 10 composed of a CPU, a microcomputer 11 for driving the MIDI sound source 10 and a RAM, an AD converter 12 for converting an audio signal obtained from the pickup 3 into a digital signal, and a microphone connection terminal 13. AD converter 14 for converting an audio signal to be converted into a digital signal, an output of a MIDI sound source 10 obtained through a microcomputer 11, and an AD converter 1.
2. A mixer 15 with a digital effector for processing and synthesizing the output of the AD converter 14, a DA converter 16 for analog-converting the output signal of the mixer 15, and an amplifier 17 for amplifying the output signal of the DA converter 16. Consists of. The control unit 6 is connected to the microcomputer 11 and has the control select switches 18a, 18b ... Which control the microcomputer 11 as shown in FIG. The control state of the microcomputer 11 can be visually confirmed. Further, the magneto-optical disk drive 7 serves as an external storage device of the microcomputer 11, and an interface 20
The MIDI file data pre-written on the magneto-optical disk 21 can be read by being connected via the. Reference numeral 22 is a MIDI information input terminal connected to the interface 20 for connecting an external MIDI device.

The magneto-optical disk drive 7 reads the MIDI file from the magneto-optical disk 21 so that the No. of the music, the music name, etc. are displayed on the liquid crystal display 19.
Can be displayed on the screen, and the screen immediately after reading the start, stop, pause, music volume, guitar volume,
The volume of the microphone, the tempo of the music, and the key of the music are displayed, and the switches 18b, 18c ... Can be intensively operated. When the switch 18a is pressed to perform the next screen operation, the tone of reverb, chorus, distortion, delay, etc. can be controlled. Further switch 18a
When is pressed to display the third screen, the sound effect of the voice input from the microphone connected to the microphone connection terminal 13 can be controlled, and the reverb, chorus and other desired types can be selected and their strengths adjusted. Switch 1
When 8a is pressed to display the fourth screen, MIDI information sent from an external device through the information input terminal 22 can be controlled, and channels 1 to 16 based on the MIDI standard are displayed on the liquid crystal display 19 and necessary channels are displayed. Can be selected.

In addition to the digital signal output from the MIDI sound source 10 via the microcomputer 11, the mixer 15 also inputs the digital signal of the pickup 3 output via the AD converter 12 and the microphone connection terminal 13. The voice signal of the microphone connected to
The digital signal is converted by the D converter 14 and input. Therefore, in the mixer 15, the guitar input and the audio input can be subjected to the effect processing similarly to the MIDI part, and the volume and pan can be controlled by the MIDI signal.

The output of the mixer 15 is the DA converter 1
6 is converted into an analog signal, amplified by an amplifier 17, and uttered by a speaker 9. Therefore, from the speaker 9, the performance by the MIDI file read from the magneto-optical disk 21 and the guitar performance input by the pickup 3,
The voice input from the microphone connection tank 13 can be reproduced together.

Therefore, if a desired song is selected while playing the guitar, it can be used as a musical instrument karaoke, and if different arrangements of different types are prepared for one song depending on the type of musical instrument and the level of the playing technique, You can easily make selections according to your taste and performance level. In addition, since it has an effector function that modulates the sound quality from the microphone and the tone of the guitar, it is possible to set the mixing according to your preference, and key transpose, tempo control etc. as a song control function in almost real time. It can also be set arbitrarily with.

[0012]

As described above, since the karaoke playing stringed instrument of the present invention has a MIDI sound source, a MIDI system such as a mixer with a digital effector, etc. built into its body, it has good portability. There is an advantage that you can enjoy minus one performance anywhere, that is, musical instrument karaoke. In addition, the audio signal obtained from the pick-up is also converted into a digital signal and processed and synthesized by a mixer with a digital effector like the output of the MIDI sound source, so a digital effect is applied in the same way as the accompaniment sound of a MIDI file. This has the effect of facilitating sound quality adjustment.
