I'm learning 2 row C/F Hohner melodion I find this a useful way to explore the keyboard and pick out new tunes. My family loves it that I can use headset so they don't have to listen to endless religions of the Skye Boat Song
Funny but useless
We're absolutely listening to all your suggestions on how to continue to improve the Hohner apps on Android!
Compared to versions 1.1 and 1.2, for this version we optimized the graphics to provide as large a button size as we could on the typical Android 16:9 aspect ratio display used on the Samsung Galaxy S3 and Galaxy Tab devices.
