Origin MIDI (OMI) is is an audio format created by Origin Systems and was used in the Worlds of Ultima games of the early 1990s. The format stores game music and can be sent to various output devices including AdLib, Sound Blaster, and Roland MT-32. The actual music files from the game do not have a file extension; OMI is used to help distinguish the format since it is similar enough in structure to be confused with MIDI, but different enough to prevent most MIDI players from playing it.
Although the Worlds of Ultima games use the same engine as Ultima VI: The False Prophet (DOS), this new audio format was created by Origin instead of the earlier M format.

How to Obtain

You can study the format by using the unpack_lzc.exe tool created by the Nuvie team.
