ABSTRACT
Musical performance is a combination of the instrument and a player. The interaction between the two produces the music, and the interfacing between the player and the instrument involves the control of the instrument. The organ-type keyboard that is used as the major controller on many synthesizers seems to have been chosen for all the wrong reasons. Most synthesizers add a number of additional controllers to augment the keyboard’s. limited capability. Foot pedals and breath controllers are just some of the additional controllers that are employed to try and provide more flexible and expressive control over sounds that are merely pitched and triggered by the keyboard. Separating the controller from the sound generating parts of a synthesizer produces two separate devices. Controllers have been developed to utilize most of the available resources of the performer.
