For years I've been hand-writing my charts using Nashville Number System and then scanning them into the unReal Book app on my ipad (I play in a wedding/corporate event band with a repertoire of hundreds of songs in every genre). I'm hoping to go all-electronic and thus have been recently investigating the Nashville Numbers and 1Chart apps. One downside I'm seeing is the inability to also incorporate standard notation. When writing my charts on paper, I often find that while most of a song is easily charted using the NNS, it's sometimes necessary to precisely notate a specific one or two measure riff or basic line that is essential to the song. Does anyone know of an app or software that can do both?
