Keep the music going.

Transposing instruments use written notes that sound at a different pitch. For example, a written C on B-flat trumpet sounds B-flat. Piano Transpose uses the selected instrument’s normal tuning automatically, so you can play straight from its written part. Choose concert pitch or another tuning in Settings when needed.

Open Settings and enable Two keyboards. Each keyboard can have its own instrument, tuning and volume. Key size and note-label settings apply to both keyboards. iPhone uses a single keyboard.

Drag the highlighted area in the miniature keyboard above the keys, or tap another part of that overview. The available range follows the selected instrument.

No. You read your sheet music and tap the keys yourself. The app helps you hear the notes at the instrument’s correct pitch; it does not scan, recognize or import scores.

Check your device’s media volume and, on iPad, each keyboard’s volume. Check whether audio is going to headphones, Bluetooth speakers or another output. If sound doesn’t return after a call or interruption, reopen the app. Contact support if the problem persists.

Bluetooth audio can introduce a noticeable delay between touching a key and hearing it. For a more immediate response, try the device’s speakers or wired audio.

No. All 55 instrument sounds are included in the app and work offline. There is no sign-in, advertising or additional sound-pack purchase.

Open Settings, then About and sound licences. The app includes credits and the original notices for its instrument recordings and software components.
