Abstract
A pattern memory stores plural accompaniment patterns for each of plural accompaniment components. Each of the accompaniment components is composed of one or more musical instrument parts for an accompaniment performance. There are provided operating members which are used for selectively designating a desired component and a touch sensor for detecting an operation touch applied to the operated operating member. Any of the plural accompaniment patterns corresponding to the designated component is selected in accordance with the detected operation touch, and the selected accompaniment pattern is read out from the memory. The entire accompaniment performance pattern is provided by a combination of the accompaniment patterns thus selected for the respective components. In order to allow the selected pattern to be changed freely, modifiers representing how to make the change may be utilized by the user. In such a case, the accompaniment pattern is changed in accordance with a predetermined algorithm that corresponds to the modifier selected by the user.
