C4 modier buttons
The four buttons in this area are similar to those found on your computer keyboard (but are
independent of the keyboard modiers). Many Logic Pro functions behave dierently when
one or more modier keys are pressed in conjunction with another key or mouse click. This also
applies to the C4 control surface.
Here is a generic description of the modier button functions:
•
SHIFT: Switches other buttons to an alternate function.
•
OPTION: While held down, parameters are set to the minimum, default, or maximum value
when edited with a V-Pot.
•
CTRL: Disables the Group function.
•
CMD/ALT: While held down, parameters are edited in Fine (high-resolution) mode when a V-Pot
is turned.
