If you carry your sheet music in a laptop, AirTurn's got a USB dongle for that, but if you've migrated your musical cues to an certain slate, never fear, Bluetooth is on the way. The AirTurn BT-105 will bring the company's page turning technology to iPad, using a transmitter that attaches to standard professional footswitches, allowing you to turn full pages and half pages of sheet music while keeping hands firmly affixed to your instrument. Though there's no word on price, we imagine it'll cost close to the existing 2.4GHz version, which runs from $40 for a dongle to $100 for a package with two Boss pedals, and when it surfaces in Q4 of this year, we're hoping it will extend bicycling input to all the other wild and crazy appsyou dream up. PR and video after the break.
