More then often when I am entering chords manually following the sheet music that i am scoring I'm not sure that the chord progressions are correct. Sometimes what i've entered does not sound good or pleasing.

Is there a keyboard chord Mac program ( OS 10.9 ) that would do the job for me ?

When I really get in a bind I crank up Ballade an OS 9 program that does that for me and much more plus it provides me with chord progressions to make the music realistic and professional.
