Plug a USB music keyboard into your Mac and over 100 realistic software instruments are at your fingertips. You’ll find pianos, strings, drums, guitars, and horns — everything from bass to woodwinds. Just create a new track, choose your instrument, and play. Try the one onscreen — it can display up to 10 octaves at once and it’s resizable. Or turn on Musical Typing and use the keys on your computer keyboard to play. As you record software instruments, GarageBand can display your notes on a piano roll or as notation, complete with rests and other musical events. Edit individual notes right on the staff, then print the notation.
