This is new, and progressing function in beta state, some details are not well polished. The layer index can be changed by means of MIDI1 .. MIDI4 objects.
Here is short overview:
Surface Layers
In all tables you will see the column Layer. What it means and why it appeared in recent builds of BEYOND? MIDI controllers have many buttons, but still not enough to cover all needs, all functions of BEYOND. Number of buttons and sliders is smaller than number of BEYOND functions. In such case we need a way to assign more than one function to button (or slider). For such separation we introduced conception of layers. As example, the first layer can work with Live Control, second with…Channels, third with Effects, and so on. It work this way. For mapped BEYOND function you specify to what layer it belong. You link the MIDI message and Function, but the link work only for specified layer.
The tricky thing is – function may exists in multiple layers. As example, Blackout. This is important buttons, and it must work in all layers. Because there is a way to enable function for multiple layers.
