The present invention relates to a digital piano capable of concerto and sheet music display.

In order to teach piano lessons or songs as part of overall music education in schools, music institutes (including classrooms), or at home, conventionally, tapes in which the teacher or instructor plays or plays the songs to be taught In addition, the number of teachers is increasing day by day, and the number of teachers and instructors must be increased proportionally as well. If practical teaching methods are not planned, they are in a realistic position where rational and effective teaching cannot be achieved.

In addition, when teaching songs, the songs were accompanied by pre-recorded tapes or by piano accompaniment by teachers or instructors.

Accordingly, the present invention is capable of adjusting the speed of the song to be played after adjusting the size of the metronome to match the function of the digital piano and left hand and right hand during the piano practice, random bar repeat and practice In practice, accompaniment function, score display and playing position display function, and built-in hundreds of songs, other instruments, accompaniment by the teacher or the teacher to play the piano directly to configure the user's song composition The technical composition is described to provide a multimedia piano that not only maximizes the practice but also provides various practical benefits such as enabling individual performance.

FIG. 1 is a block diagram showing a prior art, which detects the speed and strength of a key pressed from a signal input from a keyboard, converts it into a MIDI signal, and applies it to a sound source to generate an audio signal. Only a simple piano function can be produced.

2 is a block diagram of the present invention, the power supply unit supplies a stable power for the operation of the devices of each configuration, the central control unit, the CPU and CPU program built-in ROM, the working RAM of the CPU to the keyboard unit and pedal unit After processing the input signal and external MIDI input according to the user's selection of the KEY input part, this data is combined with the data read from the music data storage device.The music data outputs the MIDI signal to the sound source part, and the music score data and the lyrics data are the image control part. It has the function to display music and lyrics on an external TV or monitor.

The keyboard unit is configured to detect the type of the key pressed by the user, the speed and the intensity of the key pressed, convert the MIDI signal into a MIDI signal, and output it to the central controller.

The pedal unit allows the user to adjust the audio signal from the sound source by pressing the volume pedal, and also sends the central signal to the central control unit by the user pressing the soft pedal to convert the MIDI signal input from the keyboard.

The display unit is composed of a liquid crystal display (LCD) and an LED, and displays an operation state sent from the central control unit.

The KEY input unit is configured to analyze the type of KEY pressed by the user and output the signal to the central controller.

The sound source unit and the volume control unit are configured to generate an audio signal by receiving a MIDI signal sent from the central control unit, and to output an audio synthesizer by adjusting the size of the audio signal with a pedal signal.

The external MIDI input unit connects to the desired MIDI instrument and sends the MIDI data of the external MIDI instrument to the central control unit for ensemble or solo. The composition music data storage unit uses CD-ROM or ROM to shake, sing, piano, It is a device that stores performance data such as music for listening, score data, and lyrics signal, and the microphone control unit and volume control unit echoes the microphone input voice signal, adjusts the delayed sound quality, and sends the volume to the audio synthesis unit.

The audio synthesizer has a function of synthesizing the adjusted voice signal and the adjusted audio signal and sending the synthesized audio signal to the audio amplifier.

The image controller converts the score data sent from the central controller into the corresponding score, and then outputs it to an external TV or monitor as a video signal, and the audio amplifier amplifies the signal sent from the audio synthesizer to drive the speaker.

3 shows a technique of separating music data and performance data from music data. The present invention stores music data and performance data in the same file, and reads music data during performance to separate data of a specific channel into music data. Send to the control.

At this time, the score is not expressed by general MIDI, but according to the present invention, the unused PATCH signal or CONTROL signal of the MIDI signal is displayed in correspondence with the predetermined score.

4 is a block diagram of concerto. The built-in music data includes performance data of all instruments, and can be used for listening when playing a song. Convert the data of the keyboard or external music to the channel of the removed instrument, and combine these signals in the data MIX and output them to the sound source.

5 is a block diagram of the left- and right-handed separation practice during the practice of piano songs. The data read from the music data storage section is divided into left- and right-handed performance data. Send it to play.

6 is a block diagram of repeating performance. When you start to play a song, store the address of the end of the performance at the repeating end address, play it one by one, and increase the performance address. When the repeat switch is pressed again, the point is set as the address of the end of the repetition, the number of repetitions is input, the specified repetition section is repeated the specified number of times, and the performance starts immediately after the end of the repetition.

7 is a flow chart that separates the musical score signal from the music data and processes it as an image. It checks whether the performance is completed by checking the playing time in STEP 1 and checks the performance of each track in STEP 2 if it is not finished.

At this time, if the score is not TRACK, skip to the performance routine, and if the score is TRACK, check if the score of the score displayed on the screen is completed with the score display display routine in STEP 3 and change to the score of the next screen.

In STEP 4, read the score data of the score, and in STEP 5, calculate the score display according to the beat and calculate the proper method of display.

In STEP 6, DATA is divided into NOTE signal, CONTROL signal and PATCH signal. If it is NOTE signal, data is calculated by note and comma. If it is CONTROL signal and PATCH signal, it is replaced by special symbol.

In STEP 7, the music information signal and the special symbol are converted into the video signal and sent to the video controller so that the score is displayed on the screen.

8 is an operation flow chart of the concerto device. Read the music data in STEP 1 to check whether this data is the end data, and if it is the end data, finish the performance. Otherwise, check if the current performance mode is the concert mode. Send the read data to the sound source and send it to STEP 5 again.In concert mode, the read data checks the data value of the instrument to be removed and SKIP if the instrument is to be removed, otherwise it sends the data to the sound source in STEP 2.

In STEP 3, read the state of the keyboard or external MIDI input, and if there is no input, increase the address of the playing position in STEP 5, go to STEP 1, repeat the loop, and if there is an input, send the input data of the keyboard or external MIDI input to the sound source.

The present invention having the configuration as described above has a major effect that can achieve a man-to-man education for each student's learning level at the same time regardless of the number of teachers or instructors when teaching a large number of students during the piano lessons It is possible to invest the time in learning because the economic advantage and the difficult and difficult performance of the teacher and the instructor do not have to first teach and teach difficult and difficult performances. Even when playing musical instruments such as violins and violins, it is possible to practice with accompaniment without any additional device.

Accordingly, the present invention provides a more economical, convenient, and scientific instrument for music learning, and is useful for making a total development in the field of music education.
