Patent ID: 8045732

Claim:
A method for a system to map a plurality of external control signals to values for one or more internal parameters, comprising: mapping each external control signal to a control signal-specific set of internal parameter values corresponding to the level of the signal, wherein each external control signal to the signal processing module is independently adjustable; combining the resulting signal-specific sets of internal parameter values to generate a combined set of internal parameter values; wherein the combined set of internal parameter values comprises (1) a single value for each internal parameter for which a value was included in at least one signal-specific set of internal parameter values and (2) for each internal parameter for which a value is included in more than one of the signal-specific sets of internal parameter values, a combined value based at least in part on the values included in the signal-specific sets of internal parameter values; wherein mapping each external control signal to a control signal-specific set of internal parameter values corresponding to the level of the signal comprises: determining if the level has associated with it a predesigned set of values for one or more of said internal parameters; in the event it is determined that the level has a predesigned set of values for one or more of said internal parameters associated with it, using the predesigned set of values as the control signal-specific set of internal parameter values for that signal; and in the event it is determined that the level does not have a predesigned set of values for one or more of said internal parameters associated with it, using interpolation to generate the control signal-specific set of internal parameter values.
