Automatic playing apparatus substituting available pattern for absent pattern

摘要

An automatic playing apparatus registers pattern data representative of a plurality of performance patterns in a storage, and sequentially designates performance patterns to form a music composition. The apparatus sequentially retrieve the pattern data of the designated performance patterns from the storage to reproduce a sequence of the designated performance patterns to undergo an automatic play of the music composition. The apparatus operates when incidentally designating an absent performance pattern which is not registered in the storage for substituting an available one of the registered performance patterns for the absent performance pattern so as to maintain the automatic play.
