The MIDI meme typically revolves around the visual complexity of Musical Instrument Digital Interface files, particularly in the 'Black MIDI' subculture where millions of notes are packed into a single track. What started as a technical standard in 1983 evolved into an internet phenomenon where composers create 'MIDI art' on piano rolls that looks like anime characters or intricate patterns. These memes usually mock the intense CPU usage required to play such files or the chaotic, overwhelming sound of thousands of notes hitting at once. It serves as a relatable trope for music producers and audio engineers who spend hours staring at piano rolls and dealing with software crashes while trying to push their digital workstations to the limit.
