Physicles is a collection of physics-based Audio Unit MIDI plugins for the iPhone. Developed by Rodrigo Roman, this free program falls under the category of Multimedia, specifically Music & Radio.

Physicles is a unique container that houses several AU MIDI plugins. These plugins utilize an underlying physics engine to generate MIDI messages based on the physical interactions between various entities. It offers a new and innovative way to create MIDI sequences.

The current version of Physicles includes two plugins: Physicle Bouncy and Physicle Gravity. In Physicle Bouncy, users can observe multiple balls bouncing inside a polygon. Whenever a ball collides with the side of the polygon, MIDI messages are generated. Physicle Gravity, on the other hand, allows users to create segments on the screen, which, when collided with by spawned balls, produce MIDI messages.

It's important to note that these plugins do not generate any sound themselves but instead focus on generating MIDI messages for further use in compatible hosts such as AUM, AudioBus 3, apeMatrix, Beatmaker, Cubasis 2, Nanostudio 2, or Sequencism.

Physicles provides a unique and creative approach to MIDI sequencing, allowing users to harness the power of physics to generate MIDI messages and create dynamic music compositions.
