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] [VIDEO]

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] [VIDEO]

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: [VIDEO] (I love the Dwarf Fortress background for this video, it absolutely nails the vibe)
