Yamaha Music Interactive has released NoteStar, a new advanced digital sheet music application for the iPad. NoteStar provides a hands-free, smooth-flowing transcription of keyboard sheet music synchronized with professionally recorded audio backing tracks that allow users to play along as if they were in the band. Sheet music display is handled automatically and the app provides playback control features including A-B looping, track muting and metronome support. A variety of note size and layout options are available with automatic sheet music resizing to provide customizable views of the sheet music and the app supports both portrait and landscape orientations. Users can also choose to play songs in different key signatures or a half or three-quarter speeds without changing the pitch. The app provides an extensive library of popular songs available for in-app purchase for $4 each; one free song download is included with online registration. NoteStar is available from the App Store as a free download.
