I figured out why I wasn’t getting data to the #ObliquePalette from the #ObliqueEasel : plugdata has inherited data types from its immediate ancestor, #puredada, and I was sending a List, not a Symbol. Which contains the same data.
The Palette was like “I don’t know what all this ‘List’ nonsense is, so I’ll just time out every single second the serial is connected.”
Now that I’m feeding it a Message of Symbols, it’s no longer giving me an error.
And yet, there’s still no output.
Moral: I didn’t leave out a cookie and a grommet for the gremlins, then forgot to blow in the cartridge.
Don’t make the same mistake I made.
I’m going to bed.
