Official MIDI Specifications

General MIDI Lite

The General MIDI Lite specification was developed to meet a particular market requirement. The specification defines three things:
  • A set of features for fixed-polyphony GM Lite devices
  • Authoring guidelines for music data in SMF (Standard MIDI File) format that is intended for playback on GM Lite devices
  • Implementation guidelines for GM Lite file players 
Note: There is also a Scalable Polyphony MIDI (SP-MIDI) Specification which compliments GML by defining features and authoring guidelines for flexible-polyphony MIDI devices and content.
