Patent ID: 8874800

Claim:
A parameter management apparatus (PMA) for an externally connected musical apparatus (XMA), the XMA comprising an XMA current buffer storing one or more values of one or more XMA current parameters and an XMA voice buffer storing one or more values of one or more XMA voice parameters, the PMA comprising: a PMA current buffer storing values of a plurality of PMA current parameters which are currently in use; a PMA voice buffer storing values of a plurality of PMA voice parameters; a parameter selection portion selecting, in a single selection of parameters, one or more PMA current parameters from the plurality of PMA current parameters and one or more PMA voice parameters from the plurality of PMA voice parameters; and a match controlling portion matching one or more values of the selected one or more PMA current parameters and one or more values of the corresponding one or more XMA current parameters in a current parameter match and matching one or more values of the selected one or more PMA voice parameters and one or more values of the corresponding one or more XMA voice parameters in a voice parameter match, the current parameter match and the voice parameter match each having a matching direction between the PMA and the XMA, the matching direction of the current parameter match being different from the matching direction of the voice parameter match for said single selection of parameters, the matching direction of the current parameter match comprising one of a first matching direction and a second matching direction, the matching direction of the voice parameter match comprising the other of the first matching direction and the second matching direction, wherein a PMA parameter follows an XMA parameter in the first matching direction, and wherein an XMA parameter follows a PMA parameter in the second matching direction.
