App: ZOA — Living MIDI Sequencer
Developer: Ryan Robinson
Genres: Musik

ZOA is a creative MIDI sequencer that is both immediate and immense.

ZOA uses a custom, musical implementation of John Conway’s Game of Life to generate melody, harmony, and rhythm. Up to four voices move through an evolving landscape of living cells, playing notes as they go. Each voice can move in a unique way, with its own pace and rhythmic pattern. ZOA includes unique features, such as note values based on the golden ratio for maximum generative fun.


Features:

- Interact with the Game of Life by touching the grid to toggle cell states
- Define your musical palette by configuring the grid settings
- Create a complex dance between four independent voices
- Free your hands to explore your synthesizers as ZOA plays them for you
- Includes ten factory presets to give you a feel for what ZOA is capable of
- Explore a focused, yet deep set of parameters

    - Send MIDI clock to external synths (standalone, experimental feature)
    - Connect to Bluetooth MIDI devices
    - Modulate ZOA's parameters in a compatible AUv3 host (audio unit)
    - Eight unique MIDI CC outputs derived from ZOA’s game of life simulation
        - Population density, fertility, mortality, stability, and per-voice random
    - Includes macOS app!


IMPORTANT:
ZOA can be used as a standalone app or as an AUv3 plugin. There are some important differences between the two. The standalone app features a simple, toggleable "Sidekick Synth" so you can quickly experiment with ZOA. Of course, you can also send MIDI from the standalone app. Meanwhile, the ZOA AUv3 plugin does NOT generate sound. Instead, you use it to send MIDI (note messages) to other apps, plugins, or hardware instruments that do the actual sound generation. AUv3 plugins must be used inside a compatible host.
