General MIDI was developed by the MIDI Manufacturers Association (MMA) as a standardized format for the sound arrangement of a MIDI.
In a General MIDI instruments are allocated to single tracks. This guarantees that a song is being carried out equally on devices that are compatible with GM formats.
The requirements for a General MIDI are 24 sounds that can be played simultaneously and contain at least 16 melody and 8 percussion voices.
The quality and implementation of single sounds differs from manufacturer to manufacturer of GM compatible sound modules. Therefore no quality standard is given for the musical reproduction.
