Piano DX Free

Good app, but here are some ways you could improve the sheet music part: 1) Add flats (replace D# and A# with Eb and Bb) 2) Add naturals (in 'Happy Birthday', for example, there are two A# notes, then an A note – without a natural, which makes it confusing. 3) Add key signatures (Happy birthday in F, Jingle Bells in G, that Beethoven one in D, etc) 4) Add 8va notation (in that Beethoven one there is a high D that can't be sightread by most pianists) 5) Add time signatures and barlines (It may get confusing for advanced pianists like me) 6) Add paired quavers/semiquavers (there are lots of quavers and semiquavers separate so it would be a good idea to make some of them paired.) Also improve the sound quality: 1) The notes can only be held down for 2-3 seconds 2) The recording of the high B failed 3) The note "F6" is out of tune. 4) The note "C#1" is out of tune. :)
