Particle Synthesizer

Draw sound. Watch it disappear.

A generative audio-visual instrument. Draw on the canvas to play notes — each stroke spawns a burst of particles and triggers a tone mapped to a pentatonic scale. The higher you draw, the higher the pitch. Controls Decay — how long each note rings out Reverb — wet/dry mix of the delay echo Size — number of particles per stroke Spread — how fast particles scatter Wave — choose between sine, triangle, sawtooth, and square oscillators Details Pentatonic scale mapping across the Y axis Web Audio API — no dependencies Ambient particle field when idle Live note display and LED trigger indicators Fully responsive — works on mobile and desktop
