## What is Physicles?

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. 

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

## Key features

- Physics-based MIDI plugin container
- Generates MIDI messages via physics engine
- Physicle Bouncy playground
- Physicle Gravity playground
- Compatible with AUM, AudioBus 3, and more
- Outputs MIDI only, no sound

### 5/5 — Fine but

*2023-03-01, version 1.02*

Work fine but hard to use on iphone
UI not optimised for a small screen
Anyway a must have with aum

### 5/5 — Surely great but do not work on IOS 15.6 (updated since)

*2022-07-29, version 1.02*

Update : Finally got it, application do not appear stand alone. I opened AUM and found it. Sorry that I misunderstood, changing the note to 5.

Original message :
It is surely a great app but when I open it it is only giving access to the manual, the app itself do not appears. I tried to remove it and load app again but no changes 🥲. @developper : if you get any idea it would be great. Thank you

### 5/5 — Fascinating - Naturalism

*2022-04-01, version 1.02*

Algorithmic sequential control lines for the AU3 world. 
I use this frequently in Audiobus. Gravity is perfect for builds and bridges.
Idensity is a wonderful target.
I don’t understand people who give dreadful ratings because they can’t use an app and don’t comprehend the description on the App store
Thank you for making these interesting plugins.

### 5/5 — actually pretty cool - please develop more

*2021-02-20, version 1.02*

I got back into using this recently. I think a lot of the interface is elegant and designed for iOS properly with double-taps and swipes etc. The freeze function is a great addition.
I’d like to control some of the elements by time rather than beats since I like to make textures which I can later bring back to the beat through filters, or not at all. So some independence from the host’s tempo would be helpful.

### 5/5 — One of the best free AUV3 midi apps

*2021-02-07*

There aren’t a lot to choose from in the free category but this one is stellar. It’s fun to use and the physics are entertaining to manipulate. Watch the 2 minute tutorial on YouTube and you’ll be up and running quickly.

### 4/5 — Great for lovers of random

*2020-06-16, version 1.02*

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.

### 3/5 — Please

*2020-04-08*

Can you get it to work for garage band on iOS

**Developer response:** Hi,
Unfortunately GarageBand for iOS does not include support for AUv3 MIDI 😔, and I cannot make it work on that app. Sorry for the inconvenience.

### 4/5 — Really cool and unique

*2019-12-27*

Probably best for experimental music because of the inherent randomness. That said, it’s super cool and I love the combinations I stumble on. Took one star off because I couldn’t zoom in on the manual (my eyes are pretty bad nowadays).

### 5/5 — Love this plugin

*2019-11-14*

Nicely done. I was looking for something like the Tombola on the Op-1 and it has exceeded my expectations.

### 2/5 — How Do I use the app?

*2019-11-07, version 1.02*

I downloaded the app hoping for what the app says it is but I got only an instruction manual on how to use it. I am confused and don’t know how to use it. Also I have tried to get it to work with GarageBand but it doesn’t want to. I don’t actually know if it is meant to.

## Version history (last 3 releases)

### 1.02 — 2019-01-03

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.

### 1.01 — 2018-08-01

Various changes and fixes

[M] Added a new mode: "frozen playgrounds" mode. By long pressing a playground, it is possible to capture a sequence of notes and change their quantization and BPM. Read the manual for more details.
[m] Added option ('Allow stuck notes', OFF by default) to indicate whether we want "stuck" notes (e.g. notes stuck in a corner) in our playgrounds.
[m] Added copy and paste playgrounds (current state).
[m] Added support for MIDI channel selection ('MIDI channel' option).
[f] Minor bugfixes.

### 1.0 — 2018-07-18

No release notes.
