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. You can also use Pilot, a companion application to ORCA.

Marabu, Orca's predecessor was created while in French Polynesia in 2017. Orca came into being in 2018-2019, its production spanning over 3 countries: Fiji, The Marshall Islands and Japan.

You can change the look and colour of Orca.

To do this, download themes. You can view the colour palettes of each theme in the preview, once you find something you like, drag the file(.svg file) onto Orca. The colours will change instantly.

These themes are part of the Ecosystem Theme, which means that you can apply a theme to any supported app (Left, Donsol, Dotgrid and Ronin).

You can also create your own themes.
