## Description

Drop colored particles into a physics world, tune their pitch by size, and let collisions with shaped bumpers turn into music that never plays the same way twice.

Particle Music is a generative music sandbox where physics makes the song. Drop colored particles into a glass playground, tilt your device — or let auto-motion drive them — and every collision becomes a note.

A particle's size picks its pitch on the active scale. Its color is yours. Its voice comes from the layer it lives in. Scatter shaped bumpers across the scene to deflect, accent, detune, filter-sweep, randomize, or echo the sounds that strike them, and a simple still life turns into a composition that keeps unfolding.

Four independent layers stack SATB-style, each with its own waveform (morph freely between sine, triangle, square, and saw), subtle pitch drift for choral breath, filter tilt, reverb send, and an octave shift so voices can sit in different registers.

What's inside:
• Up to 32 particles across 4 voice layers
• 6 musical scales plus full Scala (.scl) microtonal import
• 6 bumper shapes with spin modes and per-shape audio effects
• Per-layer timbre morph, drift, filter, reverb, and octave
• Physics you can feel — gyroscope control, edge bounce, collisions, friction, restitution
• Preset snapshots to save a configuration and return to it later
• Reverb presets from small room to cathedral

There's no timeline, no grid, no tutorial telling you what to do. Build a configuration, watch it play, change one thing, watch it play differently. Use it as a quiet background for focus, an ambient companion, or a toy to spark ideas for music made somewhere else.

Particle Music is a result of research in the Visual Arts
