Recently I have bought a Bajan accordeon. The note numbering 1 to 12 is a great help to transpose any song on the instrument. But note number 1 is always a C, even if the song is in A minor. How can I change between number 1=C scale and number 1=A minor scale?
(Choose note number 1=F in the F scale and D=1 in the D minor scale?)
Great program!!!
