HN commenters call it the best video overview of Orca, the explanation that makes the unusual interface click.

Allieway Audio gives an informal introduction and live-coding demo of ORCA, a free esoteric programming environment for building procedural sequencers from Hundred Rabbits. It walks through the interface and how to make music with it.

“It is by far the best video overview of the system that I am aware of.” (HN, 2021)

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

YouTube user Allieway Audio has started posting a series of great tutorials and introductory videos for Orca: [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: [this video] (I love the Dwarf Fortress background for this video, it absolutely nails the vibe)
