bFaaaP Pro & Switch vs MusicBall

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.

This App Store version is free, too — just install it and start playing. If you would like to help keep bFaaaP free and open for everyone, donations and support are always welcome (see the links above and at saaipf.com). Thank you for your support. You will need a bFaaaP Pro or bFaaaP Switch device to control a real pedal. Both are open hardware — visit bfaaap.com to learn how they are built and how to take part.

Drop in a song. Watch a machine get built to play it. MusicBall takes a piece of music and constructs a whole contraption around it — plates, curving rails, spiralling drops. Then a ball falls through the lot, and every note you hear is the ball hitting something. It's oddly hard to stop watching. EVERY SONG GETS ITS OWN MACHINE Change the song and everything changes. A gentle piece grows tall spirals the ball winds slowly down through. A fast one packs tight columns it ping-pongs between. Switch back and forth and you'll never see the same machine twice. YOU'LL START TO SEE THE MUSIC Every note has its own colour, and it keeps that colour wherever it turns up. A few minutes in and you're spotting a melody's repeats on the wall before you hear them come round again. PICK WHO PLAYS THE MELODY Hand the tune to a different part and the whole machine rebuilds around it. Or let the spotlight travel between parts as the piece goes on — the ball slides across to a new rig each time the lead changes. Or run two balls at once, side by side. EVERY HIT LANDS ON THE BEAT The ball never fakes it. It arrives exactly when the note does, every single time — so what you're watching and what you're hearing are the same thing happening. BRING YOUR OWN FAVOURITE Seven classics are built in to get you started: Canon in D, The Entertainer, Turkish March, In the Hall of the Mountain King, Für Elise, Prelude in C and Gymnopédie No. 1. After that, bring in anything you like — your file stays on your phone. FLY THE CAMERA Ride along with the ball, or take over: spin around it, pan across the machine, pinch to take in the whole thing at once. NOTHING TO SIGN UP FOR No account. No ads. No tracking, nothing collected. It works exactly the same in Airplane Mode.
