Abstract

Appareil acoustique (10) comprenant une pluralité d'unités de lecture (27) capables de lire des données musicales, et une pluralité d'unités de commande d'opération (47, 48) permettant de sélectionner une unité de lecture arbitraire parmi la pluralité d'unités de lecture (27) et d'exploiter la musique lue par l'unité de lecture sélectionnée. La pluralité d'unités de commande d'opération (47, 48) comprend une première unité de commande d'opération associée à l'unité de lecture sélectionnée (27). Lorsqu'une unité de lecture (27) parmi la pluralité d'unités de lecture (27), différente de l'unité de lecture associée à la première unité de commande d'opération est nouvellement sélectionnée par la première unité de commande d'opération, l'association entre la première unité de commande d'opération et l'unité de lecture associée à la première unité de commande d'opération est annulée.
