General MIDI

Lite

The General MIDI Lite specification was developed to meet a particular market requirement.

GM LITE VS. GM 1

The General MIDI Lite device specification is intended for equipment that does not have the capability to support the full feature set defined in General MIDI 1.0, on the assumption that the reduced performance may be acceptable (and even required) in some mobile applications.

GM LITE DEVELOPER INFORMATION

Recommended guidelines for Using GM Lite in Mobile Applications are included in the GM Lite Specification document. Developers are also urged to consult the GM 1 Developer Guidelines.

Developers of GM Lite players are strongly advised to keep as much flexibility as possible in how their players handle channel priorities, drum channels and other System messages. This will make it far easier for their products to be compatible with song data authored for the Scalable Polyphony MIDI specification.
