Pianoesis

Split MIDI by 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."

Piano music you can not only hear and see, but truly play. Pianoesis splits complex piano pieces into two parts — left hand and right hand. No need to think about fingering or combining both hands: choose the melody or the accompaniment, and let Pianoesis be your other hand. KEY FEATURES ◆ Voice Separation — Proprietary algorithms assign every note of complex textures to the right hand, with dedicated optimization for contrapuntal, homophonic, and chordal accompaniment styles. ◆ Multi-view Pitch Map — Circular note particles, sheet-style horizontal view, vertical waterfall, and Jump view. Four ways to see the music. ◆ Dual Practice Modes — Free and Rubato timing: it waits for you, or plays along. ◆ Track Mapping — Apply a reference MIDI's hand assignment to your own piece. Reuse proven separations with one tap. ◆ Note Editing — Assign notes to tracks manually, or delete them. ◆ Offline Library — 130 public-domain / CC-licensed piano pieces, each with verifiable source and license. Import your own MIDI files, too. PRIVACY — Parsing, separation, and playback all happen on your device. No account, no network, no data collection. WHO IT'S FOR — Music lovers who want to see the structure of music, easily experience piano playing, or play as piano accompaniment.
