MIDI files are not commonly seen in our digital entertainment. However, there are indeed MIDI files and needs for converting MIDI file to MP3 or other audio file formats. Beforehand, we’d better get something about MIDI file. Short for Musical Instrument Digital Interface, MIDI files are not actually audio files. The MIDI file contains messages that specify notation, pitch, velocity and control signals for volume, vibrato, audio panning that synchronize tempo between multiple devices. MIDI is nothing more than data – a set of instructions. MIDI data contains a list of events or messages that tell an electronic device (musical instrument, computer sound card, cell phone, et cetera) how to generate a certain sound, like what notes to play on what instruments, how loud each note is and how long it is held. That means MIDI isn’t music and it doesn’t contain any actual sounds. It’s not a digital music file format like MP3 or WAV.

Since MIDI file doesn’t include any sound, it requires special player to open and play MIDI file. MIDI files can be opened with Windows Media Player, QuickTime, Winamp, VLC, WildMidi, TiMidity++, NoteWorthy Composer, WildMIDI, Synthesia, MuseScore, Amarok, Apple’s Logic Pro, and very likely some other popular media player applications as well. You can also play MIDI files online with Online Sequencer.
