ummm.....room for improvement

1st of al, its not a whole octave (c to c) its c to b. its so incoveniant if i need it to practice piano and when my piano isnt working. also, when you press don on a key, it doesnt show you any sign what so ever that you are pressing down on that key, 3rd, you cant see the keys when you arent in full screen. Very poor, if you improve this, ill write a better review, but for now..,this thing isnt the best thing to buy and i cant believe i spent 99 cents on it. WASTE
