ABSTRACT:
A manually played control device mounted on the playing board of an electronic keyboard instrument, to be played by one hand of a player while the other hand plays the main keys. The main keys produce usual control signals whereas the control device produces electrical control or sound signals for the variation, supplementing and completion of the control signals produced by the main keys. A plurality of continuous and/or gradual control signals can be played simultaneously for a subtle control and shaping of sound parameters, such as volume, pitch, timbre and noise, through the use of a control handle which is movable in several directions and in several planes and is sensitive to the variable load by the player's hand. Special keys on the playing board and on the control handle within the range of the fingers of the hand resting on the control handle serve to generate control signals and to initiate control functions provided by electronic means to improve, advance and simplify the foundations and possibilities of the playing technique. Different repetition and damping modes of tones and sounds played with the main keys can be played with the special keys. A plurality of distinct control functions can be initiated by the special keys without disturbing the flow of play.
