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]
Strong rec Dangeranger · 2021-11 · 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 Audio[0]. It is by far the best video overview of the system that I am aware of. [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)
