A Matter of Fact

Three distinct physics-native instruments turning electron states, molecular bonds and crystal lattices into playable sound.

Central Eigensynth orbital cloud and collision trajectoriesSet 1 instrument

Eigensynth

A playable bank of oscillators derived from elemental electron configurations, with orbital clouds, probability plots and live scopes tied to the sound.

US$14.99Planned release: August 17, 2026

Central Chemical Chords molecular orbital fieldSet 1 instrument

Chemical Chords

Molecular orbitals become interval and chord systems while bond strength, length and geometry shape tuning, voicing and movement.

Central Lattice Lullabies crystal network and modal surfaceSet 1 instrument

Crystal Lattice Lullabies

Coupled oscillator networks translate phonon modes, temperature, impurities and lattice defects into resonances, mallets and evolving textures.

Eigensynth

Pluck, collide, listen.

Click an occupied mode to pluck its oscillator, then pull back and release the collision target. The impact excites linked modes while the cloud, probability plot and output scope show the response.

Chemical Chords

Chemical Chords: basic demo.

Choose a molecule, play its orbital voices and hear bond length, strength and geometry shape the tuning and voicing.

Crystal Lattice Lullabies

Lattice Lullabies overview.

Choose a crystal structure, excite its lattice modes and hear the resonant network respond through the live lattice, modal and output views.
