Request – Stave'n'Tabs: Sheet Music App Review

Really I love this app , when I prepare this I though it like any other app could and shows how a piano melody and bass together at bottom are playing on piano keys , ( a music file like any that this app supported ) I want to see which note for melody and bass together too on piano keys ( the bottom of this app ) are playing . At the some of this app past version it was possible only for melody or bass ( not simultaneous for two together ) that which piano keys at the bottom could be seen and playing . I don’t know why ? And why we couldn’t have full all piano keys at bottom ? At like other apps it is one the first ability and preliminary that user see which note ( melody and bass together ) , for every two staff playing on the piano keys . On this past app only melody or base note could be selected and be seen at piano keys and not for every two together , unfortunately at recent and new version the same this one too ( only one selection ) isn’t possible and omitted now . Please let me know more , is it any setting may be I don’t did it for ? My child is not professional player , sometimes He needs to see which note is playing on the piano keys ( simultaneous for melody and bass too ) not for one only . It is a necessary that this app should have this ability , as l told I don’t know why this preliminary ability is absent ? Anyway l like this app and l hope adding this ability and more for the next update . Good luck F. Koohi
