MIDI File Analyzer Tutorial

What is MIDI?

MIDI (Musical Instrument Digital Interface) stores music as instructions — note on, note off, tempo, instrument change — not audio samples. It's how DAWs (Logic, Ableton, FL Studio) save compositions, and how game engines reference adaptive soundtracks.

What You'll See

  • Tempo (BPM) and time signature (4/4, 3/4, etc.)
  • Song length in seconds and MM:SS format
  • Per-track breakdown: name, channel, message count, note count, lowest/highest note played
  • General MIDI instruments — 128 standard program names (Acoustic Grand Piano, Distortion Guitar, Strings, Drums...)
  • Top notes: which MIDI note numbers (translated to C4, D#5, etc.) occur most often

Common Use Cases

  • Audit a MIDI song library before importing to a DAW
  • Verify tempo and time signature of a file mailed to you
  • Debug game soundtracks that don't play right
  • Analyze a song's most-used notes for music theory homework
  • Check MIDI format (0, 1, or 2) to see if your player supports it

What It Doesn't Do

  • Play or synthesize audio — this is metadata only
  • Convert to MP3 (needs a synth + rendering engine)
  • Render sheet music (use MuseScore or similar)

Format Notes

  • Format 0: single track with all channels merged
  • Format 1: multiple tracks, one per instrument/voice — most common
  • Format 2: independent sequences (rare)
