Title
(EN) AN IMPROVED MUSICAL EXPRESSION PEDAL
(FR) PEDALE D"EXPRESSION MUSICALE AMELIOREE
Abstract
(EN)
An expression pedal for a musical instrument with conventional mechanical control means of the pedal being replaced by proximity control means. The pedal is comprised of a box-type structure which houses a proximity detector plate (H), a proximity detector circuit (I) and an audio circuit compartment (K). A heel rest (E) is provided at one end of the pedal on which a musician"s foot can pivot. A rubber floor mat (F) is attached to the bottom of the pedal, to act, together with sidewalls (B) as a shield for the detector plate (H). The pedal can be used to generate a control signal for triggering bypass switching when the musician"s foot is at the remotest proximity effect distance, the bypass switching being de-activated when the pedal is in use. This bypass switching can be used for controlling various audio or display effects.
(FR)
Pedale d"expression pour instrument musical dans lequel les moyens de commande mecaniques conventionnels de la pedale sont remplaces par des moyens de commande de proximite. La pedale comprend une structure en forme de boite dans laquelle sont loges une plaque (H) detectrice de proximite, un circuit (I) detecteur de proximite et un compartiment (K) de circuit audio. Un support de repos (E) de talon est prevu a une extremite de la pedale, sur lequel peut pivoter le pied du musicien. Une natte (F) en caoutchouc est fixee sur le fond de la pedale pour servir avec les parois laterales (B) d"ecran de protection pour la plaque detectrice (H). La pedale peut etre utilisee pour produire un signal de commande servant a actionner un commutateur de derivation lorsque le pied du musicien se trouve a la distance la plus grande pour l"effet de proximite, le commutateur de derivation etant mis hors fonction lorsque la pedale est utilisee. Ce commutateur de derivation peut etre utilise pour la commande de differents effets sonores ou visuels.
