What Maestro Pro is

Maestro Pro is a working tool for musicians. It reads your scores and follows them to the note, turns pages for you, and rehearses with a backing track, a song from Apple Music, the built-in instrument or a metronome. It also lets you write and revise the music itself.

It runs on iPhone, iPad and Mac. You can slow a hard passage down without changing the pitch, transpose for your instrument, record yourself against the score, and play along with other devices.
