You can switch between every tuning (menu ‘Edit -> Change tuning’). The fingerings for the chords are automatically adjusted to the new tuning. Your fingering favorites are used preferably. Your tuning may have a capo set.
smartChord allows you to transpose every song any number of steps up or down (change the key of the songs; menu ‘Edit -> transpose’). You can use transpose using the capo or independent from the capo.
Each song can be transposed, independent from its source. The song is kept in the original source with the chords. If you edit a song, you’ll get the original chords. But if you like, use the menu to keep the result of transposition as the original song.
There is an option to keep the fingerings when transposing with the capo.
