Abstract

PURPOSE:To reduce the complexity of a key setting operation by performing the reproduction of key converted music after finding out a key fitting an individual singer. CONSTITUTION:Numerical data inputted from an external input device 6 or data representing music and the highest key in the music are read in from a storage medium 5 in which they are housed by a highest key input circuit 1, and an individual highest key stored and made into data are read in from an individual highest key input circuit 2, then, they are stored. Stored two pieces of data are sent to a key comparison means 9, and it is judged by what number of keys the highest key of the music should be shifted, and judged data is sent to a key conversion circuit 10, and key conversion is performed based on the above information, and music software can be reproduced. Thereby, the key setting operation can be simplified.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a karaoke device that allows a singer to sing appropriately based on the key of the song to be played and the data of the highest key (pitch) that the singer can produce. The present invention relates to a karaoke device that automatically changes the key of the song being played.

[Conventional technology]

Conventional devices of this kind are designed to help singers sing properly.
A device for playing music software such as cassettes and CDs is combined with a device that has the function of switching only the keys up and down without changing the speed of the song, and the setting value is determined by a manual switch. Was.

[Problem to be solved by the invention]

In the above conventional technology, when a singer sets a suitable key,
I had to sing along with the song that was playing and repeat the settings until I could sing properly. Furthermore, the set value is valid only for that one song, and if you want to sing another song, you have to repeat the same operation again, and there is no consideration given to the setting method and continuity of the set value. Ta.

The purpose of the present invention is to find a key that suits the singer himself and play the song, and to calculate the personal highest key data by -degrees.
To provide an individual key automatic setting device for karaoke that is effective for all songs and takes continuity into consideration.

[Means to solve the problem]

The present invention stores the highest key of the song to be played when played by the input input playback device stored in the storage medium itself, or from the highest key input circuit of the song received from the input device 6. a first memory circuit that stores the highest key; an individual highest key input circuit that receives data of the highest key that the singer can produce from voice or an external input device; a second memory circuit that stores this; and the two memory circuits. This karaoke device is equipped with a key comparison means for receiving and comparing key data from a singer, and a key conversion circuit for converting the key of the song to be played based on the compared data, and provides accompaniment in a key suitable for the singer. Operation] The highest key input circuit for the song reads the numerical data input from the external input device 6 or the data indicating the song and the highest key in the song, and stores the data. The converted personal maximum key is also read and stored by the personal maximum key input circuit 2. The two stored data are sent to a key comparison means, which determines how many keys the highest key of the song should be shifted, and the determined data is sent to a key conversion circuit, which converts the key based on that information and converts the music. Play software.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the invention. In the figure, data indicating the highest key of each stroke is stored in the storage medium 5 in advance, or
Write down the highest key of each picture in the catalog of inserted songs. The highest key input circuit 1 for a song reads the highest key data from the storage medium 5 or receives the highest key data listed in the catalog by inputting the highest key data using the keyboard or button of the input device 6, and inputs the highest key data to the circuit 49 described above. 2
The singer's highest key input circuit 3 is equipped with a circuit that converts the data obtained from the microphone 4 into key data. The device 7 receives the data and stores it in the storage circuit 8. The two stored key data are compared by key comparison means 9. The comparison method will be explained using the flowchart shown in FIG. 2 and the musical score shown in FIG. If the key changes significantly, the original sound will change considerably, so the highest key is set from C to C (approximately I octave), as shown in FIG. 3, and the keys are numbered in ascending order. Then, the highest key data of the song and the highest key data of the singer are expressed by the values on the display device 13, and substituted into A and B, and the difference between them is set as C. (Step Sl)
Next, it is determined what the value of C is (step S
2) Branch into four as shown in the figure, and determine the setting value for how many keys to lower. This setting value is sent to the key conversion circuit 10 shown in FIG. 1, and the playback device fill converts the key of the music software based on the value and plays it back.

Note that each part is controlled by the CPU 12. Storage medium 5
When a song is played back using the highest key input circuit, it is stored in the memory circuit 2, so once the song is played back, the highest key is memorized.

〔Effect of the invention〕

According to the present invention, after finding a key for each singer, the key-converted song is played back, so that the complexity of key setting operations can be reduced.
