DESCRIPTION OF THE PREFERRED EMBODIMENTS An electronic music reproducing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electronic music reproducing apparatus using an electronic musical instrument represented by MIDI data. The input means 1 is used to issue commands such as reserving or selecting a song title and adjusting the pitch, and the commands from the input means 1 are sent to the song title storage means 3 and the performance data storage means 4 via the control means 2. In the song title storage means 3,
Data regarding song titles, reserved song names, and reservation order are stored, and the performance data storage means 4 also stores performance data for each song. The performance data processed in accordance with the commands of the control means 2 is sent to the performance data reproduction means 5 and output from the speaker 6. Further, video data such as song titles and lyrics related to the performance data is sent to the video data reproducing means 7 and displayed as a video on the monitor 8.

FIG. 2 shows the contents of all performance data for one song stored in the performance data storage means 4. Performance data for one song is a collection of measure data, but here it is considered as a chorus unit. In other words, it is considered as a prelude, chorus, interlude, and postlude, and various patterns are created using these as the minimum unit. FIG. 3 is a flowchart showing a method of processing performance data. A method of processing performance data will be explained using the figure. First, the control means 2 determines whether or not there is a reserved song (step 1, hereinafter S
1), and if there is a reserved song, the performance data is read. When reading the performance data, the number of reserved songs stored in the song title storage means 3 is verified, and if it is determined that the number of reserved songs exceeds a certain number, the performances stored in the performance data storage means 4 are verified. Process the data. In the figure, a certain number of songs is set to X1 and X2. However, it is assumed that X1<X2.

First, it is determined whether the number of reserved songs is less than or equal to X1 (S2), and if the number of reserved songs is less than or equal to X1, the performance data is processed as a full chorus (S3).
). The processed performance data is sent to the performance data reproducing means 5, outputted from the speaker 6 (S4), the number of reserved songs is subtracted by one (S5), the series of processing is completed, and the process returns to S1 and the same steps are repeated. Repeat the action. If the number of reserved songs is a value of X1 or more, then it is determined whether the number of reserved songs is a value of X2 or less (S6). If the number of reserved songs is less than or equal to
S9), and then proceeds to S4 and follows the same route.

FIG. 4 shows an example of processing the performance data mentioned above. For example, A is a prelude, 1st chorus, 1st chorus, and B is a prelude, 1st chorus, interlude, 2nd chorus, etc.
C is prelude, 1st chorus, interlude, 2nd chorus for the postlude.
This is an example of processing into a full chorus with chorus, interlude, 3 choruses, and postlude.

FIG. 5 is an example of a display on the monitor 8. As shown in the figure, song title storage means 3 and performance data storage means 4
Video data such as song titles and lyrics related to the performance data read from the playback section are sent to the video data reproducing means 7 and displayed as a video on the monitor 8. Note that the present invention is not limited to the embodiments described above, and various changes can be made without departing from the spirit thereof. For example, in this embodiment, at the time of playback, the control means verifies the number of reserved songs and then reproduces the performance data according to the flowchart of FIG. Since the shape of the performance data is determined at the time of reservation, even if the number of reserved songs changes thereafter, music will be played based on the previously determined performance data.

[0011]

As described in detail above, according to the present invention, the performance data for one song is divided into the minimum units of data, and the performance data is processed by rearranging or deleting the data. It is possible to play various electronic music and shorten the performance time of one song, and it is also possible to shorten the waiting time when there are many reservations, and if used for karaoke etc., the turn to sing will come quickly. It is valid.
