Abstract

PURPOSE:To easily input a musical score and automatically perform it by providing a means for memorizing a recognized result of inputted notes. CONSTITUTION:A digitizer 13 is provided which is composing an input panel in which notes are handwriting-inputted in a note recognition part 1. Processing for pattern recognition, etc., is made by a program stored in a ROM 12 as for pattern recognized in a digitizer controller 14 in a CPU 11, and handwriting- inputted notes are stored in a SRAM 4 as performing data. On the other hand, reading and writing are controlled with a CPU 21 for the SRAM 4 in a performance part 2, and a D/A converter 23 converting performance data into analogue signals for performing the performance data, memorized in the SRAM 4, as a musical piece amplifier 24, and speaker 25 are provided. This can recognize handwriting-inputted notes to enjoy automatic performance of music by simple operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic performance device that automatically stores musical note data input by a user.

[Prior Art] Conventionally, personal computers, synthesizers, electronic pianos, and the like are known as devices that perform automatic performance by inputting musical score data.

[Problems to be Solved by the Invention] However, these devices generally require specialized knowledge to input the data because they input encoded musical score data, and the data input process is time-consuming. It was easy to use.

Furthermore, the input data and the image of the music did not necessarily match, creating a sense of discomfort.

The present invention was made in view of this situation, and
This allows musical scores to be easily input and automatically played.

[Means for Solving the Problems] The automatic performance device of the present invention includes an input panel on which a staff score is displayed, a recognition means for recognizing notes input by hand on the input panel, and a result recognized by the recognition means. It is characterized by comprising a storage means for storing information.

[Operation] The automatic performance device configured as described above does not store the result of the performance, but rather recognizes the notes input by hand on the input panel and stores the recognition result.

Therefore, it becomes possible to automatically play music based on this stored data.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an automatic performance device according to the present invention, in which 1 is a note recognition unit that recognizes notes input by hand and generates performance data, and 2 is a musical note recognition unit that plays music based on the performance data. The performance section is equipped with a power source 3 that supplies the necessary power to each section of both.

The note recognition unit 1 includes a CPU 1l that controls the entire system;
and a ROM 12 in which a program for controlling the operation of the device is stored in advance.

Also provided are a digitizer 13, which constitutes an input panel into which musical notes are handwritten using a pen, etc., and a digitizer controller 14, which outputs a pattern of musical notes input by hand to the CPU 1l. The input panel is also equipped with a liquid crystal display (LCD) 15.
A predetermined display is made on D15 by the LCD driver 16. The data to be displayed is stored in the VRAM 17.

The CPU II performs processing such as pattern recognition on the pattern recognized by the digitizer controller 14 using a program stored in the ROM 12, and stores the handwritten notes in the SRAM 4 as performance data.

On the other hand, the performance section 2 is equipped with a CPU 21 that controls the entire performance group according to the programs stored in the ROM 22.

The reading and writing of the SRAM 4 is controlled by the CPU 21, and includes a D/A converter 23, an amplifier 24, and a speaker 25 for converting performance data stored in the SRAM 4 into analog signals for playing as music. Further, the output of the D/A converter 23 is outputted to the outside via a bin connector 26 so that it can be heard on another audio system.

Furthermore, an IC card 5 as an external storage device is connected to the performance section 2 via an IC card controller 27.

Next, the operation of the automatic performance apparatus having the above configuration will be explained.

The VRAM 17 stores data for displaying the staff score, and the LCD driver 16 displays the staff score on the LCD 15. The user uses a pen or the like to write musical notes on the displayed staff score.

Since the digitizer 13 is provided integrally with the LCD 15, the written notes are transferred to the digitizer controller 14.
is read by a digitizer 13 controlled by. The read note information is recognized by the CPU II and stored on the SRAM 4 as performance data. Further, the recognized musical notes are stored in the VRAM 17 and displayed on the LCD 15 by the LCD driver 16.

On the other hand, in the performance section 2, the CPU 21 reads performance data stored on the SRAM 4, and the D/A converter 23 converts it into an analog signal. analog 48
The performance signal converted into a musical number is amplified by an amplifier 24 and outputted as a musical piece from a speaker, and is also outputted to an external device via a pin connector 26.

Furthermore, the performance data on the SRAM 4 is stored in the IC cart 5 via the IC card controller 27.

Conversely, if the IC card 5 has all the performance data stored in advance, it can be read out by the IC card controller 27, stored in the SRAM 4, read out, and used for calculations.

Of course, the external storage device is not limited to the IC card 5, and any suitable storage medium such as a magnetic disk, magnetic tape, or optical disk may be used.

FIGS. 2 and 3 are views showing the appearance of the automatic performance apparatus having the above structure. In this embodiment, the note recognition section 1 and the performance section 2
It has an integral structure that can be folded like a laptop-type personal computer, and FIG. 2 is a perspective view of the computer when it is folded, and FIG. 3 is a perspective view of the device in use.

In FIG. 3, reference numeral 6 denotes an input panel composed of an LCD 15 and a digitizer 13, and necessary operation keys 7 are arranged on the operation surface.

Fig. 4 shows the display contents on the input panel 6 (LCD 15). Fig. 4 (A) shows the staff notation, and Fig. 4 (B) shows the performance data stored in the SRAM 4 on the staff notation on the LCD.
What is displayed as musical notes by the driver 16 is shown.

In addition, instead of storing the staff score in the VRAM 17,
The information may be printed on a transparent glass plate (not shown) of the CD 15 in advance.

[Effects of the Invention] As described above, the automatic performance device of the present invention recognizes and stores musical notes that have been input by hand, so that they can be played automatically without the need for skill. You can enjoy automatic music performance with very simple operations.
