A MIDI file (Musical Instrument Digital Interface) does not contain audio. Instead, it contains data: which notes are played, how hard they are hit (velocity), and the timing. Think of it as the piano roll from your DAW (Ableton, FL Studio, Logic Pro) saved as a standalone file.
"Sonnentanz," released in 2012 by the Austrian duo Klangkarussell, is a cornerstone of the melodic deep house genre. Its MIDI structure is defined by a central, organic-sounding saxophone hook that provides the primary melodic identity, supported by a syncopated bassline and rhythmic percussion. 2.
