Abstract

PURPOSE:To offer the music reproduction device which enables the random changing of keys by a controller by giving music information on variation of a sound range previously. CONSTITUTION:The information on variation of the sound range is included in performance data previously. The information on the variation is only arranged in front of a prelude part, an interlude part, and a postlude part and in front of the measure of each phrase. Consequently, the keys of music information can be varied at random.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music reproducing apparatus for business or home use that changes the range of musical tone information in accordance with changes in the range of a singer's voice.

0002

2. Description of the Related Art In conventional music playback devices, when singing a performance song along with the reproduced musical tone information, when the vocal range of the singer's voice does not match the performance song, the tone range of the reproduced musical tone information is It was possible to change it manually to suit the song being played.

0003

[Problems to be Solved by the Invention] By the way, general music playback devices can only manually change the range of the musical tone information of the played music.
Change was difficult when the key). The present invention solves the above-mentioned problems, and aims to provide a music playback device that allows a control device to change keys randomly by providing musical tone information with information on changes in range in advance. The purpose is

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a storage unit for storing musical tone information regarding the musical tones of a performance piece in a storage medium, and an audio input means for inputting a singer's voice using a microphone or the like. and an input/output control unit that plays back the musical tone information stored in the storage unit and the audio input from the audio input unit, and also outputs and controls the audio information input from the audio input unit. In this music reproducing device, the key of the Raku sound is made variable by providing the Raku sound information with key change data for changing the range of the Raku sound and giving an instruction to change the range of the Raku sound to be played.

[0005]

[Operation] According to the above structure, musical tone information regarding the musical tones of the performance piece stored in the storage medium is reproduced and outputted, and at the same time, the singer's voice information inputted from the voice input means is also outputted. Since the musical tone information reproduced here has key change data for changing the range, it is possible to perform the musical tone information by randomly changing the key according to a command from the input/output control device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a music reproducing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of a music playback device according to this embodiment. The input/output control unit 1 is in charge of overall control of the music playback device, and includes a CPU 2, a RAM
3. This input/output control unit 1 has built-in ROM4 etc.
The following devices are connected to the . The operating section 5 includes operating keys and the like, and is used to select a desired performance piece and input the information to the input/output control section 1. The storage section 6 is a storage medium that stores at least musical tone information. As shown in the figure, in this storage section 6, performance data B,
Lyric timing data C and lyric sentence D are stored. This performance data B is, for example, MIDI (Musica
l Instrument Digital I
interface) standard, and its information consists of at least the scale, sound intensity, sound length, and timbre.

The storage section 6 also stores background video data E in addition to musical tone information. This background video data E has no correspondence with the song title A and is output to the display section 8, which will be described later, asynchronously with the performance data B, and allows endless video output.

The video control section 7 inputs the background video data E stored in the storage section 6 via the input/output control section 1, and controls the display of the video E on the display section 8. The lyric sentence output control unit 9 is
The lyric sentence D stored in the storage section 6 is inputted via the input/output control section 1, and display control is performed on the display section 8. The performance control section 10 inputs the performance data B stored in the storage section 6 via the input/output control section 1, and controls the performance of the synthesizer 11 as a performance device. This performance control section 10 is capable of adjusting and controlling the reproduction timing and reproduction speed of performance data, and is also configured to receive lyric timing data C stored in the storage section 6.

[0009] Further, an amplifier 12 is provided at the rear stage of the synthesizer 11, and the output of the synthesizer 11 is amplified and outputted to the speaker 13 at the rear stage. Also, this amplifier 1
2 includes a microphone 14 as an audio input means for inputting audio;
is connected. The amplifier 12 mixes and amplifies the audio information from the microphone 14 and the musical tone information from the synthesizer 11, and outputs the mixed signal to the speaker 13.

Next, the operation of this embodiment will be explained. When a song selection command is input through the operation section 5, the input/output control section 1 searches for the selected song title A among the data inside the storage section 6, and performs performance data B corresponding to the searched song name.
, the lyrics timing data C and the lyrics sentence D are read. Furthermore, the background video data E is displayed on the display section 8 via the readout video control section 7 regardless of the song title A. Of the data read out from the storage unit 6, the lyric sentence D is inputted to the lyric output control unit 9 via the input/output control unit 1, and is displayed on the display unit 8 while being superimposed on the background image.

On the other hand, the performance data B and lyrics timing data C are outputted to the performance control section 10 via the input/output control section 1. The performance control section 10 is responsible for overall control of the music reproduction apparatus based on the lyrics timing data C, and controls the output timing of the lyrics sentence D, as well as outputs the performance data B to the synthesizer 11. The sound signal generated by the synthesizer 11 is output to the speaker 13 via the amplifier 12, and is reproduced and output as a musical performance. The singer's voice is input to the amplifier 12 as audio information via the microphone 14, and this audio information is input to the amplifier 1.
2, it is mixed with the performance information and output from the speaker 13.

[0012] Some singers are tired of singing normally and want to sing in a unique way. In order to meet this demand, the apparatus of this embodiment embeds information on changes in pitch range (key) in the performance data B in advance, as shown in the data format diagram of FIG. This key change information is stored before the prelude, interlude, and postlude.
Just place it before the measure of each phrase. That is, in FIG. 2, the shaded area corresponds to the random number roulette for determining the key, and in the first shaded area of the key change information, the key is determined by the timing at which the song is selected or started, and the first measure and In the shaded area between two measures, the next key to be played is determined by the timing at which the reference sound data is executed. Each measure contains sound data that serves as a reference for determining the key to be played next. In this way, the key of the music information can be changed randomly. Note that the present invention is not limited to the embodiments detailed above, and various changes can be made without departing from the spirit thereof. For example, in this embodiment, key change data is embedded for each bar, but it may be embedded at certain intervals.

[0013]

[Effects of the Invention] As described above, according to the present invention, the key of the performance to be played can be randomly changed by providing information on changes in the musical range in the musical tone information in advance.
You can sing along with the performance and enjoy singing.
