Swingtone: Pendulum Waves

Swingtone turns a pendulum wave into music. Glowing balls swing at slightly different speeds, each one plays a note when it strikes, and at the end of every cycle they all come back into one line. How it works • Pick a ready wave or tap Surprise me, then press play. • The balls drift through snakes, spirals and ripples, and each one plays its note when it strikes. • A countdown shows when they line up next. When they do, the screen lights up with a flash, sparks and a ring of light. • Change the balls, tempo, scale, instrument, colours or background, and hear and see each change at once. • Save your wave or share it as a video, audio or MIDI file. Features • Up to 128 balls, a tempo from 0.1 to 200 strikes a minute and cycles from seconds to hours. • 11 instruments: marimba, piano (a real recorded grand piano), celesta, kalimba, jal tarang, synth, handpan, music box, vibraphone, harp and tubular bells. • 15 scales: major, minor, pentatonic, fifth plus major or minor, chromatic, quarter tones, one tone, dorian, lydian, blues, whole tone, hirajoshi and hijaz. • 11 animations: pendulum, half disc, disc, bounce, spiral, carousel, tunnel, 3D orbits, wave, kaleidoscope and strings. • Neon gradients, rainbows, twenty solid colours and flowing colours. • Backgrounds: night, deep sea, dusk, starry night and aurora, with light trails. • 25 ready waves in five sets for sleep, calm, rhythms, cosmos and classics, such as Lullaby, Galaxy and Northern lights. • Surprise me: a new wave that always sounds good. • Your own waves: save, rename and duplicate them. • Export a video (tall or wide), audio (M4A or WAV) or a MIDI file and share it. • Background playback with controls on the lock screen. • A sleep timer of up to 90 minutes that fades the music out gently. • A live wallpaper with your wave on the home screen. • Tap a ball to hear its note, double-tap for full screen. • Portrait and landscape. • Vibration when the balls line up or at every strike, if you want it. Watch it to unwind, or let it play you to sleep.
