## What is DuoPiano?

Designed for iPhone Duo. Also works on regular iPhone. On regular iPhone, Duo Piano displays the score and keyboard together in landscape.

Play the piano keyboard and adjust range, labels, volume and sustain.
Practice bundled piano pieces, browse the online song library, or import a supported piano MIDI file.
Switch between staff notation, numbered notation and falling notes. Choose left/right hand display and adjust practice speed.
Play, pause and seek through a piece, or practice target notes in Follow mode.
Save performance key events locally, play them back and export MIDI.
Choose English, Simplified Chinese or Traditional Chinese.

Membership is required for piano play, song practice and MIDI import. Choose a monthly or annual auto-renewable subscription; prices and billing periods are shown before purchase. A 3-day free trial is available to eligible new subscribers when offered by the App Store. Payment is charged to your Apple account. Subscriptions renew automatically unless canceled at least 24 hours before the trial or current period ends. Manage or cancel your subscription in your Apple account settings. Restore Purchases is available in the app.

An optional Duo account supports Sign in with Apple or Google and can be deleted in the app. A Duo account is not required to purchase or restore membership. Deleting a Duo account does not cancel an Apple subscription. Personal MIDI files and performance recordings remain on your device unless you choose to export them.

Complex multi-instrument MIDI may not fit the practice layout. This version does not automatically transcribe arbitrary audio or video.
