About GarageBand
GarageBand is Apple's music studio for iPhone and iPad. You play Touch Instruments such as keyboards, guitars, basses and drum machines, trigger Live Loops like a DJ with Remix FX, or add a virtual session drummer who takes direction. Smart Instruments play chords and strings for you, and a plugged-in guitar runs through modelled amps and stompboxes. Songs hold up to 32 tracks with multi-take recording, mixing effects and 24-bit export, and the Sound Library adds free instruments, loops and packs. Projects sync through iCloud Drive and can become ringtones.
Version 2.3.20 (22 October) added iPhone Duo support, its release notes say, with a wide layout on the inner display. Apple hasn't shown the Duo layout, so the picture here is its iPad layout.
