<P>PROBLEM TO BE SOLVED: To output the same natural music as when a person actually plays music by giving change to tempo for each note. <P>SOLUTION: An original Musical Instrument Digital Interface(MIDI) file is provided beforehand and stored in a memory means. Then, the original MIDI file is read out from the memory means and a note is sequentially output one by one from the original MIDI file via a sound output means 13a when a user performs key entry, and a delta time in which duration of a previous note is subtracted from a difference of the key entry time and the key entry time of the previous note, is calculated. An intermediate MIDI file in which the delta time is written is generated and then, the delta time of the intermediate MIDI file is converted to a local tempo to the note and a final MIDI file is generated. <P>COPYRIGHT: (C)2007,JPO&INPIT |
