An introductory tutorial on ORCA, an esoteric programming language and live-coding environment used to create procedural music sequencers.

Get ORCA for free here: 100r.co/pages/orca.html - if you like it, make sure to donate to it's lovely creators :) Heya! I'm still working on my doubleknot+mosstone vid, but I wanted to make a quick informal video on this cool software in the meantime - it's pretty impromptu and not the best audio quality but I hope you still enjoy it! Let me know what you think in the comments and maybe I can do a series of videos exploring ORCA a little bit further and making some complete songs :) By the way, I didn't mention it in this video, but the couple who developed this software live in a studio on a sailboat, where they develop cool open source tools for artist! How rad is that?? :0 Correction, by the way: ORCA uses Base 36 numbers, not 36-Bit, and l was thinking of UDP, not OSC (though it also has OSC capabilities).

Why it's here

What people say. Recommended as the best and clearest video tutorial for understanding and getting started with the Orca live-coding environment.

On “Orca: an esolang for audio-visual live coding”

There is an excellent overview of how to use the interface by a YouTube channel called Allieway Audio0. It was the explanation that made this software make sense for me personally. 0 link to this video

On “Orca – esoteric programming language, designed to create procedural sequencers”

There is an excellent introductory tutorial to Orca by an artist that goes by Allieway Audio0. It is by far the best video overview of the system that I am aware of. 0 link to this video

On “Orca – Live Programming Environment”

YouTube user Allieway Audio has started posting a series of great tutorials and introductory videos for Orca: link to this video link To give a bit of context the primary creator of this project has been essentially living off a sailboat for the past few years and has traveled some 28000km around the world in the process. More info at their site at link :)

Love 100r! There aren't a ton of examples online, but their livecoding music software/language, ORCA, is a remarkable instrument. link I posted a clip to bsky a few weeks back: link And Allieway Audio made some great Youtube videos about ORCA too if people would like to learn how it works in more of a tutorial format: link to this video (I love the Dwarf Fortress background for this video, it absolutely nails the vibe)
