PROBLEM TO BE SOLVED: To provide a method and device for reducing a processing time and a resource required for real time adjustment while a MIDI file is reproduced. SOLUTION: A real-time dynamic MIDI controller 406 reformats the stored MIDI file 418 into the corrected MIDI file 420, and simultaneously, by removing a MIDI META event though stored in the file, unnecessary for reproduction, the MIDI file is pre-processed so as to facilitate the reproduction. The MIDI controller 406 contains an administrator 414 performing channel group formation, channel voice message group formation and their assembly so as to facilitate the control of a selected MIDI file parameter. Further, the real-time dynamic MIDI controller contains an output interface circuit for matching the transmission of one or above of MIDI files processed by the MIDI controller. |
