When I choose the song key (clef) as any value, some chords don't look right.
When the song key is C, I press the notes D-F#-A on the midi keyboard, but the A6sus4 chord appears on the "Chord Display" screen.
I know that the D major chord and A6sus4 chord also have same notes. But this triple note D-F#-A must be D major when pressed in this order.
Also, when the song clef is not selected, D major chord correctly appears when hitting the same notes.
Because of this problem, I have to use other programs while writing songs in Studio one 6. (For example Midiculous)
