- The page maps finger counts to scale degrees and says camera-free play is available through keyboard controls or on-screen pads.
Field notes
The control guide maps one through five raised fingers to scale degrees, with additional signs for other chords; hand tilt can force major or minor. The page also lists song examples with key, tempo, difficulty, and chord sequence, and links to a theremin mode and recording guide. It says the webcam model runs locally and that video is neither uploaded nor stored.
