What is the best way to create/view the chords as sheet music. I play the piano and have a classical background. For me it would be useful to get the chords out as sheet music (rather than as keyboard dots). I tried several MusicXML / Midi export methods with some of the free iOS sheet music apps. I was not happy with the results. I have not tried any non free apps. Any best practises on this?
