CMF meaning in File Type ?
Answer: What is Creative Music File mean?
The Creative Music File (CMF) is a synthesised music file format, similar to MIDI, designed by Creative Labs for use with their Sound Blaster cards. The format actually stores its song data in MIDI format but it differs in that while General MIDI instruments are standardised, CMF instruments' data are stored in the file itself, much like MOD files. This allows a large range of instruments to be used, and unlike MIDI the song should sound the same regardless of which synthesiser it is played through. While MOD files store their instruments as digital data ("samples"), CMF instruments are stored as a set of register values that can be programmed into the OPL chips that were part of all early Sound Blaster cards (a feature that made them compatible with competing Adlib cards at the time.)
Because CMF music is played through these OPL chips, it has a distinctly synthesised sound. However, in the early 1990s when the format first came out this allowed songs to be synthesised entirely in hardware, meaning the performance impact of using CMF music was very low. For this reason the music in a number of games from this era (such as Kiloblaster and Jill of the Jungle) was in CMF format.
