A rear control panel is provided for mounting instrument voice characteristic and special effects controls. A mouthpiece is provided for engagement by a player's mouth and a pressure transducer is carried in the mouthpiece for communication with the player's breath pressure and for producing a pressure signal corresponding thereto. The pressure signal is connected to a pressure attack circuit for producing a pressure attack signal. Finger pressure applied to predetermined combinations of keys provides predetermined combinations of key pulses for connection to a key decoder.
