TFMX

TFMX ("The Final Musicsystem eXtended") is a music format and replay routine written by Chris Hülsbeck around 1987, first on the C64 and then perfected on the Amiga's Paula chip. It drove the soundtracks of Turrican, R-Type and other Rainbow Arts titles, squeezing rich, sample-based music through four channels with clever effects and macros.

Unlike the tracker formats (MOD, XM), TFMX was a closed composer's tool, so ripping its tunes for scene use took dedicated players. A cult format among Amiga music archivists.
