NOTE: AU MIDI plugins are audio unit extensions that are meant to be loaded in compatible hosts, such as AUM, AudioBus 3, apeMatrix, Beatmaker, Cubasis 2, Nanostudio 2, or Sequencism. Please follow the instructions in the included manual.

Physicles is a container of physics-based Audio Unit MIDI plugins. These AU MIDI plugins generate MIDI messages through the use of an underlying physics engine, which models the physical interactions between various entities.

In this version, the following plugins are included:

1) Physicle Bouncy: In this playground, multiple balls bounce inside a polygon. MIDI messages are generated whenever a ball collides with the side of the polygon.
2) Physicle Gravity: In this playground, generators spawn balls every certain beats, which will then produce MIDI messages after colliding with user-drawn segments.

- The plugins do not generate any sound, only MIDI messages.

What’s New

Version 1.02

Introducing Physicles Gravity! A new AUv3 MIDI playground, where users can tap the screen to create ball generators, and pan one finger around the playground to create segments. MIDI messages will be created whenever a ball and a segment collide!
Users can use two finger gestures (panning and zooming) to pan and zoom in/out of the playground. Also, tap an already selected generator to change parameters such as ball spawn rate, ball velocity, and number of collisions.

In this version there are other small optimisations, such as a simpler way to activate "frozen" playgrounds - both on gravity and on bouncy.

Great for lovers of random

This little set of gravity based event generators is excellent for triggering things like Fractal Beats inside AUM, somewhat in the manner of the probably better known Bram Bos Particles and Collider. There’s a surprising amount of depth and controllability here though, that takes it beyond the Rozeta tools, and discovering how things work is part of the fun (set the triangle and square spinning by stroking them for instance.) one for the sonic experimentalists and soundscapes out there.

A suggestion

Interesting app. Would it be possible to superimpose one rotating container on to another independently rotating container so that a particle will play and bounce off the first wall it encounters? That would increase pattern complexity and would also sweep particles out of corners should they happen to get stuck.
