Abstract
Music-performance data is separated into at least note-number data, musical note-velocity data, musical note-length data and other necessary data. A primary encoded code is formed in which the note-number data, the musical note-velocity data, the musical note-length data and the other necessary data are arranged in different data fields. The primary encoded code and a playback player are compressed, the playback player being formed in software having a primary encoded code decoding function to decode the primary encoded code into the data arranged in the different data fields for reproducing the music-performance data, thus forming a first secondary encoded code for the primary encoded code and a second secondary encoded code for the playback player. The first secondary encoded code is decoded into the primary encoded code of the music-performance data. The second secondary encoded code is decoded into the playback player. The primary encoded code is decoded by the playback player, thus reproducing the music-performance data.
