Abstract

Un apparato d'esecuzione automatica d'accompagnamenti e relativo apparato di riconoscimento accordi. Secondo l'invenzione se una combinazione d'accompagnamento corrispondente ad un accordo riconosciuto non è stata memorizzata come informazione nella memoria, viene letta la combinazione tra quelle memorizzate per il tipo d'accordo riconosciuto a livello di priorità più alto e alterata per essere adattata all'accordo riconosciuto. Perciò non è necessario memorizzare le combinazioni d'accompagnamento per tutti gli accordi. Pertanto vengono calcolati i vari rivolti basati sulle informazioni dei tasti premuti così da determinare per ognuno dei rivolti, l'accordo relativo. Successivamente gli accordi così ottenuti vengono valutati nella loro importanza, e quello valutato a livello d'importanza più alto viene associato all'informazione dei tasti premuti. Non è perciò necessario memorizzare informazioni relative ad accordi in modo tale che ognuno sia associato ad una combinazione di tasti premuti. La capacità della memoria richiesta viene ridotta.
