FIG. 1 is a schematic configuration diagram of an embodiment device. This device includes a sound generation circuit 1, a coordinate input device 2 that provides the sound generation circuit 1 with frequency information that determines the pitch of the sound, and time information that determines the length of the sound, and a sound that the sound generation circuit 1 generates. and a speaker 3 that outputs. The processing device 4 inputs sound-related information from the above device and performs information processing such as generating music or automatically creating musical scores, and is composed of, for example, a personal computer. The musical score produced by this processing device [4 is outputted via an output device 5, and the produced music is outputted from the sound generation circuit 1 via the speaker 3.

The sound generating circuit 1 is constructed as shown in FIG. 2, for example. This sound generation circuit 1 is basically a voltage controlled oscillator (VCO) 1 which receives frequency information regarding the pitch of a sound as a voltage and generates a signal with a frequency corresponding to the voltage value.
1. The multi! (i. It is composed of an amplifier 14 which drives the speaker 3, and a amplifier 14 which drives the speaker 3. Here, the frequency information and time information regarding the sound are each given as digital values. , D/A converters 15.16 are provided at the input stage for inputting each of these pieces of information, and each piece of information converted into voltage values via these D/A converters 15.16 is converted into a sample・Hold circuit (S)
l) said vc011 via 17.18, M M
V12 is now input to l#N.

Note that 31-117.18 above performs a sample operation in connection with the gate operation of the gate circuit 13, and when the gate processing for input information of one note is completed, information regarding the next note is input as a sample. It has become a thing.

On the other hand, the coordinate input device 2G that inputs information regarding the sound into the sound generation circuit 1 configured as described above, for example, the third coordinate input device 2G.
It is configured as shown in the figure. The coordinate input device 2 is composed of, for example, a pressure-sensitive tablet device, and its position coordinate input surface is divided into a sound information input section 21 and a menu information input section 22.

The menu information input unit 22 is configured to input, for example, articulation related to music,
In order to input information such as tempo, time signature, timbre, volume, etc., and information instructing the processing device 4 to perform the processing, the position coordinates are determined corresponding to each of these menus (instruction information). . By selectively instructing the coordinate position of this menu information input section 22 to be suppressed using a writing instrument such as a pen, the indicated position coordinate information is input to the processing device 4, and the coordinate position is determined corresponding to this position coordinate information. is converted into menu information.

Further, the sound information input section 21 has, for example, its vertical axis direction determined in correspondence with the pitch of the sound, and its horizontal axis direction determined in correspondence with the length of the sound. At the left end of this sound input section 21, a staff representing the pitch of the above-mentioned sound is written with a "G" clef symbol and a "F" clef symbol, and the position coordinate input screen corresponds to this staff. The vertical axis direction corresponds to the pitch of the sound. Further, at the lower end of the sound information input section 21, various musical note symbols representing the length of the sound are written. These musical note symbols are arranged in descending order of the length of the note, and the horizontal axis direction of the position coordinate input surface corresponds to the length of the note.

When a certain position on this coordinate input surface is instructed to be suppressed using the writing instrument or the like, information on the position coordinate is simultaneously given in the vertical axis direction and the horizontal axis direction.

For example, when inputting the position coordinate A in Fig. 3,
This represents the so-called "one point C" sound of a whole note. Also, if position coordinate B is specified, the sound of a quarter note "one point G" will be expressed, and if position coordinate C is specified, 16
This will represent the diacritic "he" sound.

However, information indicating the pitch and length of such a sound is
The data is input to the sound generation circuit 1 as digital data indicating the X-coordinate position information and Y-coordinate position information of the coordinate input device 2. In accordance with these digital data, the sound generating circuit 1 generates a signal and a gate signal of a frequency corresponding to the information, as described above, and generates and outputs each of the tones.

Thus, according to such a sound information input device, by selecting and instructing the coordinate input surface of the coordinate input device 2 according to the image of the sound to be input, a sound corresponding to the specified coordinates is generated. .

Therefore, by checking this output sound, finding the desired sound, and inputting instruction information for importing this sound information into the processing device 4 from the coordinate input device 4, the information on the desired sound can be transferred to the processing device 4. 4 will be input. Therefore, it is possible to easily and accurately input sound information without having any knowledge of music scores, and for example, as shown in Figure 4, by inputting sound information in sequence, music etc. can be easily created. becomes possible. In other words, it is possible to freely input any sound via the coordinate input device 2, and even a person who is not particularly familiar with music scores, keyboards, etc. can input the sound while checking the desired sound. . Therefore, for example, even a visually impaired person can easily create music by inputting desired sounds.

Note that the present invention is not limited to the embodiments described above. For example, by associating sounds and figures, it is possible to input the input figure while confirming it with the sound. Furthermore, the settings of the coordinate axes in the coordinate input device may be determined according to its specifications.
