I use Barfly, and really like its intonation options. Just intonation is particularly well-suited to the bulk of the stuff out there in abc (european-based traditional and early music,diatonic, doesn't go modulating all over the place....), but it has to be based on the tonic note you are actually using. D major and E dorian are NOT the same scale at all!
The equation of key signature with key or tonality is based on the modern pre-eminence of keyboards, frets, and such. Folks just assume that there are only 12 (equally-tempered) notes to choose from. The result is the loss of a lot of the flavor in music, IMO. Dan Gellert To subscribe/unsubscribe, point your browser to: http://www.tullochgorm.com/lists.html
