Abstract
An electronic musical instrument incorporates one or more pressure sensitive push-button controllers actuable independent of the keys or other note selecting elements of the instrument to vary a corresponding number of musical parameters. The specific controllers provide a sensitive, smooth, repeatable parameter variation in response to both the location and the force of the player's touch.
