Upload your sheet music from your computer to Dropbox, then open them using the app. Alternatively, you can put music directly on your tablet. PDF, JPEG, PNG and GIF files are supported. For images files, one folder full of images == one piece, so remember to use a separate folder for each piece. Supports bluetooth page-turner pedals (e.g. Pageflip Cidada) on Android 4.4 and later. You'll need to supply your own sheet music, a few sample pieces for piano are included so you can try out the app. Note that the app doesn't play music for you, it's just a viewer.</br></br></br></br>
