Midi file sources

Obviously these aren't the only places to find Midis, but with these three, you can get almost anything

Conversion

  • One note at a time, so simplify your Midi file (e.g. OnlineSequencer)
  • Uses the highest note within the same column
  • Threshold is applied globally, so preferably convert in batches
  • Brackets are used if max length is too small to contain the note sequence
  • Flats are only available using Note Override
  • Notes are constrained to C3-B5. For example, F1 and F3 will be treated as the same note unless changed in Note Override
  • All instrument tracks are merged together

Preview colors

  • <5: Next note to be played
  • 1: Played notes
  • <▲2: Not yet played
  • <▼6: Notes played in 1s or more
  • >8: Notes played in 0.2s or less
  • >▲6: Notes played in 0.1s or less

Red is not inherently bad, but if theres alternating notes, the song might be impossible to play
