Abstract
A real time dynamic MIDI controller pre-processes MIDI files to facilitate playback by re-formatting stored MIDI files into a modified MIDI file format and simultaneously eliminating MIDI META events that are stored in the file, but unnecessary for playback. The MIDI controller includes an administrator to effect channel grouping, channel voice message grouping, or a combination thereof, to facilitate the control of selected MIDI file parameters. The real time dynamic MIDI controller also includes an output interface circuit to coordinate the transmission of one or more MIDI file that the MIDI controller has processed.
