TODO update

Debug View

NanoKontrol2 Controller mapping

In blue is a sample "stage" as most sources/effects use a combination of 4 stages (see table above)

⚠️ you'll need to change your NanoKontrol2 settings to remove the "toggle" behavior of the buttons and use "external" led control

Frequently Asked Questions

Why "steel"?

FORGE is a concept which is intended to be derived onto other forms (like Raspberry PI). In order to differentiate between them each would be name after a different alloy.

FORGE (steel) describe the linux version.
