The "{0}" branch contains all item lists. An item list e.g. is a colorlist or a gobolist. You can use those Lists in several places in DMXControl. A gobolist can be configured in properties of a device. Same with colorlist. You can use the lists in some effects as parameters, too.

Bank-ID(GUID), e.g. {936DA01F-9ABD-4D9D-80C7-02AF85C822A8}

Bank-Name e.g. "New Bank"

False: In case Value is out of bounds, min / max value is set, e.g. Setting Pan = 200° on a Device with Max Pan = 110° will set the 110°.
True: Out of bounds values will be ignored, e.g. Setting Pan = 200° on a Device with Max Pan = 110° will set nothing, Device won't move.

This defines how the HAL handles shared wheels (e.g. Colors and Gobos on the same wheel).
FreeUp: Wheel is considered free when a default value (e.g. White for Color or Open for a Gobo) is set. Other value takes precedence.
LTP: Whatever last value is set, it will be kept until new value overrides it.
