If youve had problems using this piano, its just that you dont know how to. When you do you will find the endless possibilities it has. I am a piano player and I dont expect to replace a real grand piano with this. That said, it is the best tool to save your ideas while on the go. You can record, transpose the very responsive keys, change the look of it, get bigger keys, smaller keys and it is by far the best sounding piano sound in the "i" world. Keep up the good work!
