CBA app

[vivdunstan]

Got myself a chromatic button accordion app for my iPad, so I can practice more using that, not just when I get my new French CBA accordion out. I am still very much in the beginning stages. Chromatic button accordion - specifically C system in this case - is new to me. My French box only has all black keys, so it’s interesting to see white for naturals and black for flats/sharps in the app.
