The DirectMusic Segment is a proprietary file format was created by Microsoft Corporation. These files can be played with DirectMusic API using Microsoft Software Synthesizer or any installed MIDI output device. Since DirectMusic provides DLS support, SGT files often coming with sound banks, thus increasing the fidelity of a song.

SGT files contain playing order and track information. Segment files always come with Style files, because they contain all required melody pattern information.

Segment files has some improvements in comparison with MIDI or RMI, for example:

  • External DLS sound bank support (more than one)
  • Pattern randomization (each time you play a song, it can sound different)
