This app fits its description I personally love this app  and use it very frequently because when my Orchestra is given new pieces to learn  we get a Midi which we can disect to guide us as well as sheet music. The only other thing I had hoped for  which is why I held a star back  is being able to playback when the screen is locked. I'm hoping that you guys will see the importance of that feature as well.
