Explore the instruments, learn how they work, and check their release status.
Physics-driven note generator
Turn falling grains into evolving melodies. Pitch, weight, gravity and bouncing collisions shape notes and rhythm.
Stereo tape-loop delay + spring reverb
Build echoes that wander, stretch and regenerate. A movable tape mechanism meets a modeled spring tank.
Tape and spring for the modular world
Bring the tape machine into your patch. Add voltage control, physical tape gestures and dedicated spring routing.
Falling grains and evolving sound for quiet listening. No DAW or plug-in host needed.
Simple listening sessions
Choose a sound, set a session length and let the grains unfold. A gentle fade brings timed sessions to a close.
Shape your own sound
A hands-on space for falling grains, an oscillator, filters, delay and reverb. Explore slowly and save a sound you like.

Neon Lava is an independent software workshop exploring how playful interfaces can change the way we make music.
Gravity becomes rhythm. A moving reel becomes a gesture. A spring becomes a texture. These tools invite you to listen, experiment and discover something you didn't plan.
Built with AI assistance, shaped and tested by Neon Lava.
