Abstract

To simplify playing of an electronic instrument and to avoid the otherwise clearly recognizable synthetic sound quality, the operating elements are arranged in a wind or blowing body constructed and playable similar to a mouth-harmonica. These operating elements comprise a pressure sensor responsive to the blowing and suction air current or stream of a human being and which is coupled to a mouthpiece displaceable along the wind or blowing body, and a number of position sensors which respond in accordance with the momentary position of the mouthpiece. The pressure sensor and the position sensors are coupled to an evaluation circuit which is structured such that it generates, as a function of the response of these sensors, the control voltages required for controlling the synthesizer.
