Particle Synth

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
