Musical tone control apparatus mounted on a performer's body

Abstract

A musical tone control apparatus having first and second detectors mounted on a player's arm for detecting bending angles of the player's joints, and a musical tone control data generating circuit worn on the player's waist for generating musical tone control data based on output signals of the first and second detectors. The musical tone control data generating circuit is connected to the first detector via the second detector through a single common cable. Hence, the number of common cables can be reduced to a minimum, allowing free movement of the player. Further, the first detector having a potentiometer comprises first and second links rotatably connected at their ends so that the links rotate in a bending direction of the player's joint, a resistance element provided at the first link, and a sliding contact provided at the second link. The sliding contact, keeping contact with the resistance element, slides thereon with the rotation of the first or second link. The potentiometer produces a signal between the sliding contact and the terminal of the resistance element in response to a bending angle of the player's joint. Hence, the detector can be made thin, allowing free motion of the player's arm.
