Let the system hear the piano, see the voices, and play along with you. No worrying about where your fingers go, no puzzling over how the hands fit together — pick the melody or the accompaniment, and Pianoesis becomes your other hand. A self-developed voice separation engine, track mapping, and note editing work together to give both hands a fair share of every piece. In Pianoesis, piano music is not only to hear and to watch — it can be played by everyone who loves it.
Score view, vertical waterfall, and the Jump skyline — note timing, velocity, and voice colors at a glance.
Built-in algorithms split complex textures into hands and voices. Listen to one, mute the rest, master it measure by measure.
Apply a reference MIDI's track split to your target MIDI — proven voice assignments, transferred directly.
Warm-up on the home screen and the studio's play-along, each with free and elastic tempos: it waits for you, plays with you, and stays in sync both ways.
Delete, edit, and export back to MIDI — round-trip faithful, preserving tempo curves, pedals, and measure lines.
130 public-domain / CC-licensed piano pieces included, with per-piece source and license attribution.
Parsing, separation, and playback all happen on your device — no account, no network calls, no data collection.
