I recently started using pianobooster,and it's great!
But there is no way to mute the hand I am practicing while still hearing the other hand. I noticed I can mute 'parts' but both hands are on the same part. As of now, I hear both the notes I hit and the notes that the program plays, with a small delay; which is pretty confusing.
A 'mute current hand' check-box in the hands section would be greatly appreciated.
