SoundToMIDI original annotated format illustration. Plain text only; NOT a patch or firmware file. Do not transmit this text to hardware. Raw SysEx: F0 [identification and message data] F7 The bracketed part is a description, not valid hex data. Standard MIDI File: 4D 54 68 64 = ASCII MThd File header is followed by track chunks containing timed events. Raw SysEx bytes and an SMF track event have different framing. Renaming .syx to .mid does not build a MIDI container. No manufacturer-specific restore or firmware command is supplied.
