Abstract

L'invention porte sur un dispositif utilisé avec un instrument de musique à clavier comprenant une partie de saisie de son, une unité centrale et un module d'affichage qui permet de visualiser les touches de l'instrument correspondant au son saisi. Au repos, le dispositif a plus ou moins les mêmes couleurs que les touches de l'instrument. La démodulation de la tonalité permet de calculer la gamme la plus proche et le niveau de déviation à partir du son saisi. Ce niveau de déviation apparaît sur le module d'affichage représentant la gamme la plus proche et correspond aux couleurs, à la luminosité et à la fréquence de scintillement du module d'affichage adjacent, de telle sorte que l'on perçoive le dispositif sous forme de touche lumineuse. Le module d'affichage peut, mieux que les touches, servir à distinguer la déviation la plus subtile et les différentes composantes de l'harmonique. Ce dispositif peut d'ailleurs être séparé en plusieurs pièces qui peuvent être montées ensemble afin de constituer un dispositif monobloc.
