Quiet Music has released MotionTones, a generative instrument you play with physics.
Users drop balls onto a 2D canvas. Gravity pulls them down, they bounce off the frame and off any walls, circles, triangles and gravity fields you draw, and every collision plays a note from the scale or chord you have set, voiced by one of 25 internal ambient instruments. A handful of balls becomes a living, self-playing pattern that never repeats the same way twice, and reshaping the space reshapes the music.
Alongside the free-falling balls sits the Bounce engine: cinematic balls that bounce in time with the host to lay down arpeggios and rhythmic patterns, with nine shapes and a step-grid Custom mode featuring per-step accents, swing, octave spread and a one-click Euclidean generator.
Features
- Generative instrument driven by a real-time 2D physics world: balls fall, bounce and collide, and every impact plays a note.
- Draw the space: walls, circles, triangles and gravity fields reshape the motion and therefore the music.
- 25 internal ambient instruments (kalimba, handpan, marimba, bowls, bells, pads, chimes, felt piano and more).
- 62 built-in scales, many from handpan tunings, plus a 45-chord library and a custom scale and chord builder.
- Reference tuning including 440 Hz, 432 Hz and the Solfeggio frequencies.
- Bounce engine: tempo-synced bouncers with 9 shapes, plus a step-grid arpeggiator with accents, swing and a one-click Euclidean generator.
- Note-range and anti-repetition controls, an internal reverb with a long tail, an echo, and a rain and forest ambience layer.
- 10 canvas themes, 13 ball palettes and 3 atmosphere variants.
- MIDI in (spawn balls), MIDI out to drive other instruments, and internal capture with drag-to-DAW as a MIDI clip.
- 65 factory presets, built into the plugin and deployed automatically on first launch.
