By default, the Control position is in focus. The rightmost stack indicates the influence of each Source on the Macro Control. Use 4 to cycle through the stack or press 2 in order to select a particular Hardware Source like adjusting a parameter.
Once a Hardware Source is selected, 1 and 3 will also be available, now providing all involved assignment aspects. When 1 is in Mode, the selected aspect can be edited there as well (but the aspect can only be selected on the Unit).
Pressing 1, 2 or 3 a second time will return to the default focus.
Press 1 to focus on the current Source and adjust its position like a parameter.
This will cause a modulation and may affect other Controls and parameters as well.
Press 2 to focus on the Source selector. Use the selector like a parameter to select any of the eight Hardware Sources.
Press 3 to focus on the amount of the current Source on the selected Control. Adjust the amount like a parameter.
Pressing 4 focusses on the rightmost stack of Sources and cycles through it. The eight sliders indicate the amounts of each Hardware Source on the selected Control. The selected element in the stack represents the corresponding amount and can be adjusted like a parameter.
The top-center parameter group Hardware Sources and Amounts
provides access to all Sources and their amounts on Controls, represented as a modulation matrix. Items of interest can be selected and adjusted like parameters.
