Jean-Michel Jarre - 1993 - Chronology 4 - MOD File.

MOD is a computer file format used primarily to represent music, and was the first module file format. MOD files use the “.MOD” file extension, except on the Amiga which doesn't rely on filename extensions; instead, it reads a file's header to determine filetype. A MOD file contains a set of instruments in the form of samples, a number of patterns indicating how and when the samples are to be played, and a list of what patterns to play in what order. In the original MOD file the minimum time frame was 0.02 seconds, or a «vertical blanking» (VSync) interval, because the original software used the VSync timing of the monitor running at 50 Hz (for PAL) or 60 Hz (for NTSC) for timing.
