Abstract
Optional accompaniment patterns are created on the basis of a plurality of parameters. Thus, by changing the values of the parameters to be supplied as necessary, accompaniment patterns can be created in an unconstrained manner. By time-varying at least one of the parameters, an optional accompaniment pattern can be created in such a manner that a desired accompaniment tone is sounded at a desired time point, and an accompaniment pattern can be changed freely. A performance state of an performance operator such as a keyboard may be detected, so as to change the parameters on the basis of performance states detected at least for a current time and a given past time. This permits parameter control reflecting a changing real-time performance state. Alternatively, a parameter may be prepared in accordance with input performance information so that an accompaniment pattern is created on the basis of the prepared parameter. At least one of the parameters may be modulated in real time via a relatively simple operator such as a modulation wheel.
