Note Rider

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 540.5 Hz, 56 cents sharp of C5, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

Steer into each note's lane as it arrives (arrows, a swipe or a finger). ♪ Your song opens MIDI or audio.

A song comes down the track as glowing notes: its melody, low notes in the low lane and high notes in the high one. Steer the sled into each note's lane as the note arrives and it plays for its own length, so catching every note plays the whole tune; a missed note stays silent. Pick the instrument at the top: piano, guitar, steel guitar, harp, organ, synth, or vibes.

The built-in tunes are Ode to Joy, Twinkle, Twinkle, Little Star and Frère Jacques. Or open your own with ♪ Your song: a MIDI file, or a recording, whose tune a note finder hears on this device; each caught note then plays its own slice of the recording. In 2D on a phone held upright, the notes fall down three lanes side by side; on a wide screen they slide in from the right. The 3D button turns the track into a road coming toward you. The file is read on this device and never leaves it.
