Abstract

La présente invention aborde le problème, pour un équipement dont la configuration implique l'utilisation d'une molette pour effectuer une opération de « scratch » et une opération de « lecture de repère d'échantillonneur », de refléter précisément l'intention d'un utilisateur. Selon la présente invention, un lecteur/mixeur DJ (10) a une molette dotée d'un capteur tactile et est équipé : d'un premier moyen de détermination d'opération (120) pour déterminer si une opération effectuée avec la molette est une opération de « scratch » afin d'effectuer la lecture conformément au sens et à la vitesse de rotation de la molette, ou une opération de « lecture de repère d'échantillonneur » afin de poursuivre la lecture lorsque la molette est touchée ; et d'un moyen de commande de lecture (140) destiné à commander la lecture selon l'opération déterminée. Le premier moyen de détermination d'opération (120) identifie l'opération de « lecture de repère d'échantillonneur » lorsque la quantité de rotation de la molette après avoir été touchée est inférieure à un angle prédéterminé, et identifie l'opération de « scratch » lorsque la quantité de rotation de la molette après avoir été touchée dépasse ou est égale à l'angle prédéterminé.
