Abstract:
A storage medium for storing a mapping file defining a set of timbres and mapping a plurality of waveforms to the set of timbres according to performance information, the mapping file comprising a set of information blocks corresponding to the set of the timbres, the information block containing specification information for specifying waveforms associated to the corresponding timbre, and selection information for selecting one or more of the specified waveforms according to the performance information to thereby map the selected waveform to the timbre, whereinthe storage medium stores a first mapping file defining a first set of timbres and containing a plurality of waveforms originally mapped to the first set of timbres, and a second mapping file defining a second set of timbres and containing attribute information for linking the second mapping file to the first mapping file to enable mapping of the waveforms contained in the first mapping file to the second set of the timbres, such that the second mapping file may involve an information block containing specification information for specifying waveforms contained in the first mapping file.
