The PageFlip Butterfly is a wireless Bluetooth pedal designed to meet the needs of musicians and people with disabilities who struggle with the challenge and inconvenience of page turning. As the successor to our original PageFlip Cicada dual pedal, the Butterfly incorporates a whole set of features suggested by our Cicada users: added heft, more rugged construction, a longer 30-minute inactivity period before entering sleep mode, and a totally silent pedal action that mimics the feel of our premium Firefly pedal. The PageFlip Butterfly works with iPads and Android tablets under select apps that accept keyboard commands. By simply tapping the dual pedal of the PageFlip Butterfly, digital content can now be flipped or scrolled in either the forward or reverse directions for convenient hands-free reading. The pedal also works with any software on Windows, Mac, and Linux computers. The pedal emits a keypress with each tap so any app that responds to a Bluetooth keyboard will also work with our pedal.
