Parts can be slowed down, looped and even eliminated to help you to learn new riffs. Play back MP3s using Variable Speed Audition, which slows down the speed without changing the pitch, and sections can be seamlessly looped while practicing tricky passages. Songs can even be pitched up or down to match the tuning of your instrument or vocal range, so you van play in any key. The mic input lets you to play along with multi-effects, including a vocal canceller so you can sing along with your favorite bands. A tuner, metronome, and built-in rechargeable battery are also built- in.
