DuetScore

DuetScore is a collaborative, real-time sheet music reader and PDF score annotation studio designed for duos, ensembles, teachers, and solo musicians.

KEY FEATURES:
• Real-Time Score Collaboration: Rehearse together across devices with sub-15ms CRDT synchronization.
• Teacher "Follow Me" Viewport Mode: Guide students through measures in real time with synchronized scrolling.
• Specialized Notation Stamps: Classical guitar PIMA stamps (p, i, m, a, c), LH numbers, string indicators, radial barre chord dials, slurs (ligado), violin marks, and piano tools.
• Metric Pulse Ruler: Drag pulse rulers across measures with straight, compound, tuplet subdivisions, and polyrhythm rails.
• Hands-Free Page Turning: Turn pages hands-free using front-camera facial gestures (long blinks and lip movements). Camera frames are processed strictly in local device memory and never recorded or sent.
• Spatial Audio Notes: Pin audio recordings directly onto measures.
• Instant Blank Scores: Create blank manuscript scores on the fly with customizable paper tones.
