  The cancellation determination means 86 determines whether or not the output of the performance music by the performance means 84 has been canceled before the normal end. The normal end means that the output of the performance music reaches the end and ends, in other words, that the user sings the performance music to the end (to leave it to output). Specifically, the cancel determination means 86 determines whether or not a predetermined cancel operation has been performed by the operation panel 32, the remote control device 52 or the like when the performance means 84 is performing a karaoke performance. . In other words, the cancel operation is a performance stop operation before the output of the performance music is normally ended, or in other words, a skip operation for skipping the performance music being played at that time. When the cancel operation is performed, the output of the performance music by the performance means 84 is terminated at that time, and it is determined by the cancel determination means 86 that the performance music has been canceled.

  When the determination by the cancel determination means 86 is affirmed, information on the canceled performance song determined to have been canceled is stored (accumulated) in the cancel database 58. Preferably, attribute information predetermined for each performance song is stored as information on such a canceled performance song. This attribute information is, for example, information on the genre to which each performance song belongs, the singer name predetermined for each performance song, the announcement date of each performance song, or the tempo of each performance song. As information on this tempo, for example, information on which rank the tempo of the song corresponds to is based on the time signature, etc., is practical, but whether it corresponds to high tempo or low tempo It may be rough information. Also, the time from when the performance means 84 starts outputting the musical composition until the cancel determination means 86 determines that the cancellation of the output of the musical composition is measured, and the performance music with the time as a parameter is avoided. The level (how much the user dislikes the performance piece) may be additionally stored in the cancel database 58 in association with the attribute information. It is considered that the performance music (or attribute information) is strongly avoided by the user as the time until cancellation is shortened. Therefore, by adding such a repelling level, the information of the canceled music is further practically used. Can have sex.

  The extraction unit 88 extracts a predetermined number (single or plural) of performance songs from the plurality of performance songs stored in the karaoke database 54 based on the information of the canceled performance songs stored in the cancellation database 58. . Preferably, a predetermined number of performance songs are extracted based on the attribute information stored in the cancel database 58. That is, with respect to the attribute information stored in the cancellation database 58, the performance music having the attribute information is extracted so as to avoid as the number of stored information increases. For example, when the accumulated number of attribute information stored in the cancel database 58 is greater than or equal to a predetermined number, the performance music having the attribute information is not extracted and is randomly selected from the performance music not having the attribute information. A predetermined number of performance songs are extracted. Alternatively, the extraction is performed so that the accumulated number of attribute information stored in the cancellation database 58 is inversely proportional to the number of performance songs having the attribute. Here, the above-described avoidance level may be included in the determination element. Further, the extracted music piece may be selected in combination based on a plurality of types of attribute information. For example, with regard to a plurality of types of attribute information stored in the cancel database 58, a performance song having at least two (or three or more) pieces of attribute information whose accumulated number is a predetermined number or more may be avoided. .

  Preferably, the extracting means 88 is a predetermined number of performance songs out of a plurality of performance songs stored randomly in the karaoke database 54 without being based on the information on the cancellation performance music stored in the cancellation database 58. Can be extracted. For example, when a predetermined number of performance songs are extracted from a plurality of performance songs stored in the karaoke database 54, a part (for example, about 10%) of the predetermined number of performance songs is the cancel performance song. A possible way is to include performance songs randomly extracted from all performance songs that do not depend on information. Further, practically, the extraction means 88 does not need to perform any of the plurality of performance songs stored in the karaoke database 54 until the information on the cancellation performance music stored in the cancellation database 58 reaches a predetermined amount. Although a certain number of performance songs are extracted for the purpose, the user's preference is strongly reflected in the cancellation of the performance songs, and it is easy to grasp the tendency of the songs to avoid, so only a relatively small amount of information is accumulated in the initial stage of use Therefore, such information can be used for extraction of performance music.

  FIG. 5 is a flowchart for explaining automatic music selection / performance control by the CPU 34 of the karaoke apparatus 12 and is repeatedly executed at a predetermined cycle.

  First, in step (hereinafter, step is omitted) SA1, it is determined whether or not automatic music selection control is started by performing a predetermined operation by the operation panel 32, the remote controller 52 or the like.

Are extracted and stored in the RAM 38 or the like as a reserved music list. Next, in SA4 corresponding to the operation of the performance means 84, karaoke performance control of the performance music is performed according to the performance order of the reserved music list created in SA3. Next, in SA5 corresponding to the operation of the cancel determination means 86, it is determined whether or not a predetermined operation has been performed by the operation panel 32, the remote control device 52, etc., and the output of the performance music has been canceled before the normal end. The If the determination at SA5 is affirmative, the information on the canceled performance piece is stored at SA6 in the cancel database 58, and then the processing after SA8 is executed, but the determination at SA5 is denied. In this case, in SA7, it is determined whether or not the karaoke performance is ended, that is, the normal end when the output of the performance music reaches the end. When the determination at SA7 is negative, the processing after SA4 is executed again. When the determination at SA4 is positive, it is determined at SA8 whether automatic music selection control is complete. . When the determination at SA8 is negative, the processing after SA2 is executed again. However, when the determination at SA8 is affirmative, this routine is terminated.

Since a predetermined number of performance songs are extracted from a plurality of performance songs, the attribute information of the performance songs canceled by the user is accumulated, and automatic music selection according to the accumulated attribute information is performed. There is an advantage in that a performance tune according to a user's desire can be extracted in a practical manner.

  In addition, the plurality of performance songs belong to at least one of a plurality of predetermined genres, and the attribute information is a genre to which each performance song belongs. There is an advantage that performance music according to a user's desire can be extracted in a practical manner by excluding performance music of a genre that tends to be used in advance.

  In addition, since the attribute information is a singer name predetermined for each performance song, the performance information corresponding to the singer name that tends to be canceled by the user is excluded in advance. There is an advantage that the performance music according to the user's desire can be extracted.

  In addition, since the attribute information is information regarding the tempo of each performance piece, it can be made practical by a user in a practical manner by excluding a high tempo or low tempo piece that tends to be canceled by the user in advance. There is an advantage that performance music can be extracted along.

  Further, the extraction means 88 can randomly extract a predetermined number of performance songs from a plurality of performance songs without being based on the information on the canceled performance music, so that the performance according to the user's desires can be obtained. There is an advantage that it is possible to reserve an opportunity to touch a performance song that the user does not desire by including a few percent of the randomly extracted music while extracting the music.
