What are the disadvantages of MIDI music?

The main limitation of MIDI music is that it lacks the ability to reproduce real natural sounds, so it cannot be used in situations where speech is required. In addition, MIDI can only record a limited combination of musical instruments specified by the standard, and the playback quality is limited by the synthesis chip of the sound card. In recent years, popular foreign sound cards generally use the wavetable method for music synthesis, which greatly improves the quality of MIDI music.

MIDI files have several alternative formats, such as RMI and CIF. The CMF file (creative music format) is a music file used with the Sound Blaster card. RMI files are a sub-format of RIFF (resource interchange file format) files used by Windows, called RMID, which is the format that contains MIDI files.
