Abstract

PURPOSE:To offer the music reproduction device which provides a comfortable lingering note by not stopping music reproduction suddently, but smoothly ending performance after the performance of a postlude when the performance is finished halfway. CONSTITUTION:When an operation switch 5 is pressed so as to finish the performance halfway, information on the end of the performance is outputted to a control means, which reads out performance data and postlude data up to a good break point of the music, and combines and reproduces them as performance data.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music reproducing apparatus, such as a karaoke apparatus, which reads performance data stored in a storage means and reproduces it into musical tones.

0002

2. Description of the Related Art In conventional music playback devices of this type, if an end signal to stop playback is input during a playback performance, the playback immediately ends even in the middle of a song. .

0003

As described above, in the conventional music reproducing apparatus, the reproduced music suddenly stops at the same time as the instruction to end the performance is given, so that the lingering sound after the end of the performance is not desirable. The present invention solves the above problems, and
To provide a music playback device that, when stopping a performance in the middle, does not suddenly stop the music playback, but plays the postlude part and then ends the performance smoothly, giving a pleasant aftertaste. do.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a performance data storage means for storing performance data, a control means for reading performance data from the performance data storage means, and a performance data storage means for reading the performance data from the performance data storage means. In the music reproducing apparatus, the performance data storage means includes a reproducing means for reproducing the performance data based on the performance data, and an operation switch for outputting information to the control means for terminating the performance midway. The performance data is divided into performance data for each well-defined point in the song and post-performance data, and when the performance ends midway through, the control means controls the data from the storage means based on the information from the operation switch. Performance data and post-performance data up to a good break point in a piece of music are read out, and performance data that is a combination of these data is output to the reproducing means.

[0005]

[Operation] According to the above structure, when the operation switch for ending the performance midway is pressed, information on the end of the performance is output to the control means, and the control means collects the performance data up to a good point in the song and the end of the performance. The performance data is read out, and the performance data up to a good break in the song and the post-performance data are combined and outputted to the reproducing means as performance data. Thereby, even if the performance is stopped midway through, the performance can be finished smoothly.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block configuration diagram of a music playback device according to this embodiment. In the figure, a file device 1 is a storage medium that stores performance data for musical tone reproduction as digital information. This digital information is transferred to the playback device 2, converted into an analog audio signal, and output to the amplifier 3. The output of this analog audio signal is amplified by the amplifier 3, and sent to the speaker 4, where it is reproduced as sound. The operation switch 5 is used to give an instruction to stop the music playback midway through, and the playback stop information from the operation switch 5 is output to the playback device 2, so that the performance is stopped at a predetermined time as described later. The play ends after the following steps are played.

FIG. 2 is a diagram showing the format of digital information. The digital information is composed of a timbre header 6 that holds address information and timbre data 7 that holds music information. In the figure, addresses a1 to an address correspond to points (feature points) at which the music is divided, and address b corresponds to the beginning point of the post-performance part. If the feature point and the beginning of the after-play part are appropriately determined when the performance ends midway, it is possible to move to the after-play without losing the sense of rhythm. FIG. 3 is a block diagram of the playback device 2. As shown in FIG. In the figure, the controller 8 is the playback device 2.
It is for overall control, and reads out digital information from the file device 1 via the interface 9 and temporarily stores it in the memory 10. Further, the controller 8 inputs the digital information sequentially read from the memory 10 to the decoder 11. The decoder 11 converts the digital information into a PCM code and inputs it to the D/A converter 12. The D/A converter 12 converts the PCM code into an analog signal and outputs it to the amplifier 3.

When the controller 8 detects an input from the operation switch 5, it reads the data up to the next feature point, advances the address pointer to address b, and continues processing. In this case, when reading and storing digital information, it is assumed that information to be input to the decoder 11 is read in advance and stored in the memory 10 prior to inputting the information. Controller 8 inputs this to decoder 11 at an appropriate time.

FIG. 4 is a flowchart showing the operation of the apparatus according to this embodiment. The signal processing operation will be explained using the figure. When the controller 8 receives a signal to stop the performance from the operation switch 5 (YES in step 1, hereinafter step will be referred to as S1), the controller 8 reads information (S2),
Next, determine whether address ax has been read (S3)
. When read, the address pointer is changed to the address of the postlude part (S4), and the process advances to S5. If the address ax is not read in S3, the process proceeds to S5 without changing the address pointer. Further, if there is no input from the operation switch 5 in S1, the process proceeds to S5 without processing S2 to S4.

[0010] In S5, information is read, the address pointer is incremented (S6), and the information is stored in the memory 10 (
S7). Note that, after the processes of S2 to S4 have been performed, the information to be read in S5 is the post-performance data. Next, it is determined whether it is time to write to the decoder 11 (S8),
When the writing time comes, writing is performed (S9). Next, it is determined whether or not it is the end of the file (S10), and if it is the end, the series of processing is completed, and if it is not the end, the memory
Check whether there is free space in 0 (S11). If there is free space, return to S1; if there is no free space,
Returning to S8, the same process is repeated. By performing the above processing sequentially, the file device 1
The data is read out and sequentially reproduced as musical tones. In addition to what is shown above, as an example:
If an input from the operation switch 5 is detected during the post-performance part, the playback may be immediately stopped, or the playback target may include a still image or a moving image that is played in synchronization with the music.

[0011]

As described in detail above, according to the present invention, when an instruction to end the performance is received from the operation switch, the performance up to the well-defined part of the performance piece is performed, and then the postlude part is played. Since the performance ends from the beginning, the performance can end smoothly without spoiling the atmosphere. Therefore, it is effective when you want to play a large number of songs within a limited time.
