Method of compressing, transferring and reproducing musical performance data

A data decompression method comprising the steps of:

• decoding a first secondary encoded code into a primary encoded code of music-performance data in which at least note-number data, musical note-velocity data, musical note-length data and other necessary data are arranged in different data fields;
• decoding a second secondary encoded code into a playback player 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;
• and
• decoding the primary encoded code by the playback player, thus reproducing the music-performance data.
