So you’re on the bus and some old dude is coughing up a lung while a 2-year-old is bawling her eyes out as the windows creak with every bounce, when all of a sudden it hits you: this would make the perfect beat. If you’re traveling with the new Akai MPC Fly for the iPad 2, you can make that music magic on the fly (get it?). The first music production center created specifically for the iPad 2, the Fly combines 16 backlit MPC pads with a dedicated iPad app featuring a four-track mixer, effects, a sound library, sample editing, and more. The double-hinged case connects the tablet to the hardware, giving you extra battery juice, too. Don’t miss your stop.
