Abstract
An electronic musical instrument is constructed to carry out an edit work of control parameters and a trial play for evaluation of the edit work. The control parameters are registered in a hierarchical format to define a plurality of hierarchical classes. A first hierarchical class is designated as an object of the edit work. A control parameter belonging to the first hierarchical class is changed to carry out the edit work. A second hierarchical class is designated as an object of the trial play independently from the first hierarchical class. In response to a trial command, a tone generator generates a musical tone based on a control parameter belonging to the second hierarchical class to thereby carry out the trial play. Further, a third hierarchical class preceding the second hierarchical class can be designated such that a control parameter belonging to the third hierarchical class is inherited to the second hierarchical class for use in the trial play.
