## What it is
Orca is a two-dimensional esoteric programming language where every letter of the alphabet is an operator, designed to quickly create procedural sequencers. It ships as a livecoding desktop/browser application (built with Electron/JavaScript) that sends MIDI, OSC, and UDP to external audio and visual software rather than synthesizing sound itself.

## Use cases
- create procedural music sequencers with letters
- livecode MIDI patterns into Ableton or Renoise
- send OSC and UDP control signals to SuperCollider or VCV Rack
- generate Euclidean rhythms and algorithmic melodies visually
- experiment with a two-dimensional esoteric programming language
- perform live audiovisual sets via livecoding

## When to choose
- you want a visual, grid-based livecoding environment for sequencing external gear or DAWs
- you need MIDI, OSC, or UDP output to drive audio/visual tools
- you enjoy esoteric languages and want to learn an unusual programming model
- you want an offline-first tool that runs on desktop or in the browser

## When to avoid
- you need a synthesizer or built-in sound engine - Orca only sends control signals
- you want a conventional text-based programming language for general-purpose development
- you need polished, production-grade music production software
- you require extensive documentation or mainstream community support
