PURPOSE:To generate an accompaniment pattern corresponding to choice, and to output an accompaniment sound signal by selecting arbitrarily accompaniment pattern data set and generated in advance by selecting and combining arbitrarily data of each part for constituting the accompaniment pattern from in plural accompaniment pattern data. CONSTITUTION:When a performer turns on a power source of a main body, an initial processing is executed. As for a tempo processing, when it is decided that a tempo-up SW is depressed, a value of a tempo data register TR is increased, and a tempo is raised. As for a rhythm switching processing, when it is decided that a rhythm selection SW is switched, the corresponding rhythm number is written in a rhythm number register, and a display processing is executed. When the display processing is executed, a rhythm switching processing is finished. Subsequently, after passing through auto operation mode processing, an acamp mix mode processing, a tone color switching processing, a rhythm reproduction processing, and various switching processings, the processing returns to a main operation. In such a way, by repeating the loop processing, a rhythm sound is sounded in accordance with the rhythm number corresponding to a value shown by the rhythm number register. |
