I'm currently working on my first mapping set for the Xone K2.

It's the only piece of gear I'm using for DJing, therefore I'm going to use latching layers red + amber.
I'm on channel 15 with latching layers set Number 3 (top buttons and knobs).

RED layer is the mixer for 4 decks, with various controls such as
loop size and on/off, start stop sync monitor, volume faders, browse and load etc.

AMBER layer is for FX 1 to 4. The buttons for FX on/off and the knobs for amount.

Right now I've finished setting up the RED layer, which is for the 4 decks mixer.

Next is the AMBER layer for FX. And that’s where is the problem.

First of all, when I set my AMBER layer by pushing the layer button once,
I notice the top buttons do not turn amber when I push them. They don’t go red either,
they just remain off. And the knobs are still behaving as if they were still on the RED layer,
i.e. they are still EQing.

Next, when I start selecting a button, I check the codes on A&H Xone K2 manual.
For example, I want to set the first button of the 2nd row, and set it so that it toggles
the first effect of FX Unit 1. I use the “C6" code. It doesn’t work at all. It does nothing.

Can you help me? I think there’s something I’m missing...
