Pianoesis is a fully offline rhythm-piano duet platform with zero learning curve. Import a local MIDI file or a solo piano recording and get a playable score in one tap. No keys to aim at — tap anywhere on screen to play. The tempo is entirely yours, so every performance stays true to the score yet sounds unmistakably like you. Play solo and the app is your duet partner; in Duo Mode, play both hands yourself — or split them with a friend, one hand each. DUO MODE In landscape, the iPad screen splits into two mirrored halves, one hand on each side. Play with both hands yourself for the full two-voice experience, or split the piece with a friend — one hand each. The two sides stay in sync — all you do is keep the beat. ▪ Built for iPad: the split layout, touch targets, and navigation are tailored to two-hand play on the big screen ▪ Duo Sprite Jump: twin sprites leap in sync, with live scoring and sync halos for even more ensemble fun WHY IT ALWAYS SOUNDS GOOD ▪ Every note lands right: the melody is locked to the source score, so any tap hits the correct pitch. ▪ A perfect duet by design: the app plays the other hand in real time — two-hand harmony without the coordination practice. ▪ True to the original: your part and the accompaniment both follow the original score. ▪ Two sound sources: a warm, lifelike MIDI piano, or the original piano recording in lossless quality. Switch anytime. OUR SIGNATURE VISUAL — THE TAIJI SPINNING STAFF On the home screen, treble and bass notes drift out along a slowly spinning taiji staff — a signature animation that brings the idea to life: 88 keys become one, and the app is your duet partner. MORE WAYS TO SEE THE MUSIC ▪ Taiji spinning staff ▪ Horizontal score ▪ Sprite jump ▪ Vertical waterfall FOUR WAYS TO SEPARATE VOICES ▪ Ready-made tracks: pick one hand from a two-track MIDI and start playing. ▪ Smart separation: single-track MIDI or piano audio is split into melody and accompaniment automatically. ▪ Track mapping: carry a proven left/right-hand split from a reference score over to your piece. ▪ Fine editing: hand-assign individual notes for tricky passages. FULLY OFFLINE ▪ Everything runs on-device. No account, no uploads. ▪ No ads, no in-app purchases, no subscriptions ▪ The built-in library is fully licensed for free distribution — per-piece sources and licenses are listed under "Copyright" in the library ▪ Universal: iPhone, iPad, and Mac. SUPPORTED FORMATS ▪ Scores: MIDI (.mid / .midi) ▪ Audio: MP3 / WAV / FLAC / M4A / AAC — solo piano recordings work best SUPPORT & PRIVACY ▪ Website: https://pianoesis.com ▪ Privacy policy: https://pianoesis.com/privacy ▪ Contact: support@pianoesis.com
