Gravity Machine
Generative touch instrument
About
Create music by manipulating a miniature solar system. Fling orbs that bounce off walls, generating notes based on physics and chosen scales. Customize worlds, sounds, and tunings for unique generative compositions.
What's New in Gravity Machine
1.1.37
October 5, 2026
Draw your own world. A new CUSTOM plane shape: tap it, draw one loop on the plane, and that is your boundary. Where you start drawing is the low note and pitch climbs the way you drew; the outline glows brighter as the notes rise. Cleaner top bar: tuning now lives on the scale strip's TUNING chip, which makes room for the Gravity Pulse label on iPad. Saved plane shapes now come back correctly when you reopen a session.
MoreFAQ
What is Gravity Machine?
Gravity Machine is a touch instrument that generates music through physics-based interactions. You manipulate orbs within a miniature solar system, and their collisions with walls create notes and melodies.
How does Gravity Machine create music?
Music is generated as orbs bounce off walls. The impact point determines the note, and the physics of the bounce dictate the timing. You curate the environment and physics to shape the resulting sound.
Can I choose the musical scales and tunings in Gravity Machine?
Yes, Gravity Machine offers 16 scales and 11 tuning systems, including 12-TET, just intonation, maqam, and shruti. You can also change the key dynamically over time.
What world shapes are available in Gravity Machine?
Gravity Machine provides eight different world shapes for orb bouncing: rectangle, circle, triangle, hexagon, pentagon, octagon, diamond, and star. Each shape influences the ricochet and sound characteristics.
Does Gravity Machine have ads?
No, Gravity Machine does not contain advertisements. It is a premium application with a one-time purchase.
What devices does Gravity Machine support?
Gravity Machine is available for iPhone, iPad, and iPod. It is designed for iOS devices.
Can Gravity Machine be used with other music apps?
Yes, Gravity Machine supports AUv3, allowing it to be used as a plugin within hosts like GarageBand, AUM, and Logic Pro. Each orb can also send MIDI to drive other instruments.
