Minimum match score

Default is 0.75. Lower values find more matches but may be less selective.
Higher values are stricter but may leave more measures unchanged.

Enable limited key/mode substitution checking
Tests selected alternate key/mode choices for uncertain or incorrect K: tags.
Chord matching may be slower when substitutions are used.

Enabled substitution choices:

K:D (two sharps) may also be tested as Edor, Bmin, or Amix. K:G (one sharp) may also be tested as Dmix or Ador. K:C (no sharps or flats) may also be tested as Ddor or Amin. K:F (one flat) may also be tested as Gdor or Dmin.

Additional key/mode options:
Only enable these if your source tunes have K:G or K:A tags and you do not get good results using the more common substitutions above.

K:G (one sharp) may also be tested as Emin. K:A (three sharps) may also be tested as Bdor.

Advanced Settings

Fallback match percentage

Default is 75%. If no normal match is found, the tool will use a lower-scoring fallback match down to this percentage of the Minimum match score.
Lower values add more chords but may be less accurate; higher values are more selective.
