After uploading the Layout Fn acts as Pn (only with the Custom binary file)

With the custom Layout binary file, the Fn acts as Pn instead of Fn. Here the export: export (18).txt Thanks

Just tried it, it works exactly like how you set it up. Can you explain in detail in what profile with what key or key combination were you expecting a different behaviour?

after uploading the Custom Binary in the Core, pressing Fn shows up the lighting commands (QWE keys lighting up). The problem is solved uploading the Vortex Binary instead. Did you test the Custom or the Vortex binary?

[TsFreddie]

I used Custom, and it works fine. But if Vortex version works for you then that's great.

Also I don't have a RGB core, and I have no idea RGB core can use MPC since the only firmware is out before RGB core. 😑
