Orca is an esoteric programming language, designed to create procedural sequencers in which each letter of the alphabet is an operation, where lowercase letters operate on bang, uppercase letters operate each frame.

The application is not a synthesizer, but a flexible livecoding environment capable of sending MIDI, OSC & UDP to your audio interface, like Ableton, Renoise, VCV Rack or SuperCollider.

Learn more by reading the manual, or have a look at a tutorial video. If you need help, visit the chatroom or the forum. If you don't already have the Uxn emulator, see the installation guide.
