We all know that MIDI files are not actual sound file. A MIDI file actually contains no actual sound. Short for Musical Instrument Digital Interface, MIDI file contains nothing but data that instructs what notes are played, when they’re played, and how long or loud each note should be. MIDI files don’t contain actual audio data and are therefore much smaller in size. MIDI files are basically instructional files that explain how the sound should be produced once attached to a playback device or loaded into a particular software program that knows how to interpret the data. There are multiple media players that could open MIDI files, like Windows Media Player, QuickTime, Winamp, VLC, WildMidi, TiMidity++, NoteWorthy Composer, WildMIDI, Synthesia, MuseScore, Amarok, Apple’s Logic Pro, etc. Midi Sheet Music, a portable program even shows you the sheet music in real time as the audio plays. It also lets you convert the MIDI file to sheet music that you can print or save to your computer as either a PDF or in multiple PNG image files.
