【實用音樂app】Kepler's Orrery Lite|最夯免費app-綠色工廠好玩App

Kepler's Orrery Lite is a gravity simulator that composes and playsambient music. In other words, it's a generative music system that uses gravityequations as its driving force. Each world starts with its own initial conditions, and then theplanets and gravity wells attract each other, swirl around, andcollide according to the laws of physics. Each world is different --even changing the initial conditions a tiny bit makes the simulationcome out differently. Then there's the music: each world plays its own "song," which changeswith every different simulation. Whenever a body hits something itplays the next note on its melody. Each world has a different set ofmelodies that play on different instruments. Some worlds make slow andambient music; others are random, sharp, and surprising.You can play with the physics: change the gravitational constant; add"antigravity" or friction; visualize the force fields and velocities. You can also change the initial conditions of a world: with the worldeditor, you can change the mass, positions and velocities of the bodies and then restart the world to see how itcomes out different. Turn on tilt gravity to let the real world influence the simulatedworld.Kepler's Orrery Lite is a free version of Kepler's Orrery. The freeversion has fewer worlds and not as many soundbanks. For more worldsand more varied sounds, upgrade to the full version.
