Oh that’s what you meant. It seems obvious now, hehe. Anyway, I haven’t tried the plugin with Darktable yet but I’ll try that later today. For now I have all of the midi codes in this google doc along with a few notes.
The Hue Saturation and Lumination might not be super straightforward to implement and the functionality of the color wheels is a little strange, but I went into those details in the doc.
