1. A system for controlling a parameter, comprising programming means for programming said parameter, characterized in that
the system comprises:
drawing means for enabling a user to create a drawing;
the programming means being arranged for converting said drawing to a programming of said parameter, each point of said drawing
having an x-coordinate and a y-coordinate with respect to two orthogonal coordinate axes, said x-coordinate determining a
point of time in said programming, the programming means being arranged for identifying a stroke in said drawing, and programming
said parameter in accordance with at least one property of said stroke, the programming means being arranged for deriving
a value of said parameter from a thickness and/or a color of said stroke at a certain point of time corresponding to the x-coordinate.
