The complaint about not being able to play more than one octave is understandable but guys if they made the keys any smaller youd be pressing double keys. One recommendation I can make to the developer is to make the keyboard zoom and scrollable this way a swipe takes you where you need to go rather than tap on the keyboard map. And the zooming allows you to have as many keys as you want to see. I think it might be more efficient to move around the keyboard this way. Still waiting for the updates.. Keep up the great work!
