<P>PROBLEM TO BE SOLVED: To perform an appropriate automatic accompaniment pattern without breaking a rhythm pattern in the automatic accompaniment pattern, eve when a tone is changed. <P>SOLUTION: The record of sound generating information of the automatic accompaniment pattern including the tone of musical sound to be generated, and sound generating start time and sound generating time of a musical tone to be generated, is stored in a ROM 12 and a RAM 13, for each channel. The CPU 11 of an electronic musical instrument compares the time length of a sampled waveform data with an index for indicating the tendency of the sound generating time for each channel, and finds a channel including the index similar to the time length of the waveform data. Referring to the sound generating information of the channel including the similar index, the CPU 11 generates the record of the sound generating information in which the tone of musical sound to be generated is made the tone of the sampled waveform data, and stores it in the RAM 13. <P>COPYRIGHT: (C)2010,JPO&INPIT |
