ABSTRACT:
Mapping a plurality of external control signals to values for one or more internal parameters is disclosed. Each external control signal is mapped to a control signal-specific set of internal parameter values corresponding to the level of the signal. The resulting signal-specific sets of internal parameter values are combined to generate a combined set of internal parameter values. The combined set of internal parameter values includes a single value for each internal parameter for which a value was included in at least one signal-specific set of internal parameter values. For each internal parameter for which a value is included in more than one of the signal-specific sets of internal parameter values, the combined set of internal parameter values includes a combined value based at least in part on the values included in the signal-specific sets of internal parameter values.
