<p><P>PROBLEM TO BE SOLVED: To prevent a player from having the feeling of incompatibility without interrupting a sound performance for any pattern variation pattern of different performance time by a small sound data amount at the time of executing the sound performance by using sound data in accordance with the pattern variation pattern. <P>SOLUTION: The length of the sound data of BGM accompanying the pattern variation pattern is fixed and whether or not to repeatedly execute the BGM without interruption is decided depending on whether or not the pattern variation patterns of a plurality of different time widths are under the performance in the end period of the output of the BGM. Thus, the BGM is not interrupted in the middle of the sound data and the feeling of incompatibility to the player is dissolved. Also, since the BGM is prevented from being ended in the middle without increasing the sound data amount more than needed and without performing complicated control, device constitution is simplified, and the reduced portion of a data capacity can be also utilized for a new performance, for instance. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
