Pianoesis is a piano playing and playback app. Based on track division or voice separation, the user chooses which part to play, and the app automatically accompanies with the rest — it is the user's "other hand." It includes multi-view pitch visualization (horizontal score, vertical waterfall, circular particles, Jump view), playing modes, note editing, track mapping, MIDI import/export, and a built-in offline library. Target audience: piano learners and music lovers who want to play pieces beyond their current level.
