Features
An 88-key piano that fits your screen
The piano uses sampled sounds with multiple velocity layers, plus an on-screen sustain control and a metronome. On a full-width iPad, all 88 keys appear in two rows. On iPhone and in compact iPad windows, you pick the keyboard range you want to play.
Record a take, get a score
Tap Record, wait for the count-in, play, and tap Stop. Give the take a title and it's saved as sheet music on your device. Recording captures the notes you play on the screen, not microphone audio, so the app never asks for microphone access.
Watch it play back
Open any saved score and press play. A cursor moves through the sheet music and the matching piano keys light up, which makes it easy to check a phrase or see what you actually played.
Import and export the formats musicians use
Import MusicXML, MXL or MIDI files, or open them straight from the Files app. Export your scores as PDF, MusicXML or MXL, or as MIDI for use in other music software. When you import a file, the original is kept and can be exported again unchanged.
A quiet place to play
No banner ads over the keyboard, no pop-ups between takes. No subscription, no in-app purchases, no account and no tracking. Piano Composer works offline, and the App Store privacy label says "Data Not Collected".
