Three different apps based on celestial mechanics. Above is RedtailWorks ORRERY Generative Modular posted just today. No additional details are provided.

Directly below is Recluse Studios' Orrery from about two months ago. You can find Kepler's Orrery in previous posts here dating back to 2007. As always, dig and explore.

"Orrery is a generative music environment where wires carry theory, not audio. You don't write every note — you set the rules, and the machine obeys them forever. Gravity becomes a tonal center. A wormhole becomes a canon machine. A supernova becomes structure.

This is the celestial canvas playing a real piece: three minutes born from a single brief — start in A minor, move to E phrygian, end in D lydian. Bells, soft pads, percussion. No supernovas. One wormhole. All sounds generated in-engine.

Orrery is deterministic by contract: the same file, the same seeds, the same performance — every time, on your machine, offline. No black box, no cloud, no subscription. The composer stays the composer. The machine does the paperwork.

Built by Recluse Studios.

1. Orrery - First Look
2. Orrery - Ouroboros

This is the celestial canvas playing ouroboros — the first demo, and the one that shows what the clock really is. A single voice walks D, F, A, C, E while the tempo itself orbits: 40 bpm, up to 280, and back down, forever. Because the clock's own rate is fed back into the clock. The snake eats its tail.

3. Orrery - Canon in Em

This is Orrery's celestial canvas playing Canon in Em — a strict three-voice canon in E minor, doing exactly what the docs always promised. One theme, eight bars, an original line. It enters, and two wormholes swallow every two-bar phrase and return it unchanged, on time: the same melody at +2 bars, and at +4 bars, forever. Pachelbel's ground, translated — i, v, VI, III, iv, i, iv, v — in natural minor, where the dominant stays minor and the cadence stays modal. 80 bpm. Four minutes. No scenes, no supernovas, no shortcuts: the form is the canon.

4. Orrery - Undertow

One static texture, three rhythms braiding against a bar.
The piece: a Glass-style additive ladder climbs D5→D6, a tresillo thumps on the grid, and a 2-in-7 euclid pattern laps at the beat but never quite lands — the one voice that refuses the bar. The polyrhythm is the entire form. In the middle section the ladder learns to breathe — ties, rests, an accented held apex — before the machine returns, unchanged.

GRAVITY IS A CHORD.
WORMHOLES ARE CANON MACHINES.

You drop bodies into a sky and wire their ports together. A clock keeps time. A key holds the tonality. A progression walks the changes, a voice-leader smooths them, and a gravity well bends everything nearby toward its centre. Wire a body's output into another's input and the second one starts listening.

Beads sit on the wires and do the arithmetic — scale, offset, clamp, curve, lag — so a die roll can drive a filter sweep and a slow contour can nudge a whole section. The machine has no opinions. It has a clock.

Kepler Orrery

YouTube via dfabrycky | February 03, 2011 |

"All the multiple-planet systems discovered by Kepler as of 2/2/2011; orbits go through the entire mission (3.5 years). Hot colors to Cool colors (Red to yellow to green to cyan to blue to gray) are Big planets to Smaller planets, relative to the other planets in the system."

Kepler's Orrery for the iPhone

"Kepler's Orrery is a generative music system that uses gravity equations to compose and play ambient music. Each simulation starts with a collection of bodies that attract each other, move, and swirl around under the influence of their mutual gravity.

When the bodies collide, they make music. Each one is assigned a melody and an instrument and plays its next note at each collision.

Simulations are set up with "world" files that specify position, mass, and velocity for each body, as well as their melodies and instruments, and world metadata that defines simulation parameters such as step size, modifications to gravitational constants, etc.

The music it makes differs with each world. Sometimes slow and ambient; sometimes random, sharp, and surprising.

While the simulations are based on gravitational equations, and therefore deterministic, from a listener's point of view, it is difficult to predict what is going to happen next, and so the soundscapes tend to remain fresh."

Kepler's Orrery -- PhaseX: 2 Mutations

YouTube via simrangleason.

"Same world as PhaseX, but with mutation: every time a body hits the center square, its mass changes. Maybe larger, maybe smaller. If it gets small enough it becomes a point, and leaves a trail. Since mutation adds randomness, it comes out different every time. Here are two takes."
