DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance apparatus for performing an automatic performance based on music data composed of a series of performance data over a plurality of tracks.

[0002]

2. Description of the Related Art Conventionally, as an automatic performance apparatus as described above, it is possible to set, for each track, a reproduction mode such as a mute ON / OFF state of music data composed of a series of performance data over a plurality of tracks. 2. Description of the Related Art There is known an automatic performance device which incorporates a sequencer function and performs an automatic performance in a reproduction mode of each track. The number of tracks included in the sequencer incorporated in such an automatic performance device is determined at the design stage in consideration of usability and the like. For example, one track having 16 tracks is used.
There are known an automatic performance device incorporating a function of a six-track sequencer, an automatic performance device incorporating a function of a five-track sequencer having five tracks, and the like.

An automatic performance device having a function of a 16-track sequencer has a high degree of freedom in setting a reproduction mode of music data, and can obtain a reproduction mode according to a user's preference. For example, sections such as drums, percussion, and SFX (sound effect) belonging to a part performing a rhythm performance are assigned to each track, and the reproduction mode of each section is individually set. However, when the user of the automatic performance device is a beginner, an advanced usage method of setting a reproduction mode for each of 16 tracks is rarely used.
Rather, there is a problem that the degree of freedom of setting is too high and the usability is poor.

However, if beginners improve, there is a problem that the degree of freedom of setting is insufficient and the usability deteriorates, and it is uneconomical to replace the automatic performance device. Usually, there is no compatibility of music data between sequencers having different numbers of tracks, and when the music data is converted in order to obtain compatibility, the performance content may be changed.

[0005] For this reason, it is said that if an automatic performance apparatus having a function of a sequencer having a small number of tracks is replaced with an automatic performance apparatus having a function of a sequencer having a large number of tracks in accordance with progress, replacement of music data or the like is required. Problems and song data for sequencers with a large number of tracks,
Although the expression is generally richer than the song data for a sequencer with a small number of tracks, an automatic performance device with a built-in 16-track sequencer function is required to reproduce the song data with a rich expression for a 16-track sequencer. However, there is a problem that it is difficult for a beginner to enjoy an automatic performance based on expressive music data for a 16-track sequencer.

[0006]

The above-mentioned problems are as follows.
This is not a problem limited to an automatic performance device having a function of a six-track sequencer or an automatic performance device having a function of a five-track sequencer, but is an automatic performance based on music data composed of a series of performance data over a plurality of tracks. This is a problem that generally occurs in an automatic performance device that performs a performance.
