A method and computer program product for adding additional functionality to a graphical control for use in a computer program. The method requires providing a graphical control that is displayable on a display device where the graphical control has at least one associated input or one associated output. Initially, the graphical control does not have an associated function. A user can then select a function from a list of functions to associate with the graphical control. The list of functions is associated with computer code for implementing the functions on a particular digital signal processor. The computer system determines whether a new input or output needs to be added to the graphical control based upon a selected function from the list of functions. The computer system also determines if the graphical control should be stacked or repeated. A plurality of functions may be associated with a single graphical control. In certain embodiments, a plurality of different digital signal processors is associated with a single graphical control.
