Soltet is a music production tool, a physics playground, and a virtual zen garden rolled into one satisfying toy. Balls fall, bounce, and collide; every collision plays a note. Arrange the pieces, tune the key, and watch a composition come to life. There's no timeline to edit, no notes to enter by hand, and unlimited musical possibilities.
Balls collide with Shapes to trigger notes in real time, powered by a real physics engine that affects volume and stereo positioning. Gravity, bounciness, wind, and drift are all yours to control. Small changes cascade into completely new rhythms and melodies.

Use multiple instruments, edit effects, and record WAV + MIDI.
Expanded gameplay, sequenced movement, and advanced settings.
The most simplified experience with one melodic sound on a fixed play area.
Find unique grooves with organic timing or snap your hits to a grid. Instruments can trigger their notes randomly or sequenced up, down, or ping-pong for fun arpeggiated melodies. Spawners can be sequenced with a 16-step grid for easy beat making.

Customize instruments or upload your own samples. Edit a full real-time effects chain. Sculpt anything from crisp plucks to washed-out ambient drones.

Deep cosmetic theme controls. Edit the colors, lighting, and other visuals. Every composition can look as distinct as it sounds.



Musicians looking for a spark of inspiration.
Producers who want quick, exportable WAV + MIDI ideas.
Tinkerers who love watching systems come alive.
No musical training required. No wrong answers.
