bFaaaP Pro & Switch turns head movements into piano sustain-pedal control, so you can play the pedal completely foot-free. It is the companion app for the bFaaaP barrier-free assist pedals — one app that drives two devices, depending on your instrument: - bFaaaP Pro (acoustic pianos): a motorized device that physically presses the real sustain pedal. It anchors with an inflatable "airback" — non-destructive, no bolting — and self-calibrates. - bFaaaP Switch (digital pianos): switches the sustain electronically through the pedal jack. Small, light and motor-free. Using the front camera, the app detects the angle of your head and converts it into pedal ON/OFF signals, sent over Bluetooth Low Energy to the bFaaaP device on your instrument. The same head-angle control works for both devices. This lets people who cannot use a foot pedal — including wheelchair users and players with limited leg mobility — enjoy expressive, pedal-based performance. WHO IT IS FOR - Pianists who cannot operate a foot pedal - Music therapy, special-needs and inclusive music education - Anyone exploring accessible, barrier-free music making HOW IT WORKS - Detects head angle with the front TrueDepth camera (ARKit face tracking) - Converts the angle into sustain pedal ON/OFF - Sends the signal over Bluetooth Low Energy to bFaaaP Pro or bFaaaP Switch PRIVACY - The camera is used ONLY to read your head/face angle. - That value is processed on-device, used to generate the pedal signal, then discarded. - No face data, image or video is stored or shared with anyone.
