• Key analyzation
KANTAN Chord automatically analyzes the song's key and displays it in red text with a yellow background banner.
When the key changes during a song, it will be displayed with additional banners.
E.g. "Key:E(-3)" or "Key:Ab(+1)"
Numbers such as (-3) and (+1) represent half steps. If your instrument can transpose, try adjusting to these numbers.
If the key analyzation is wrong or is difficult to play, try adjusting the analyzation sensitivity.

- Ignore +-5 key changes
When changing to a dominant (+5 half steps) or subdominant key (-5 half steps) , chords used will be very similar to its original key. When this option is turned on, KANTAN Chord will ignore +-5 key changes and stay in its original key.
