Examples of Logical Operators

Logical operators determine the precise state required in order for

an event to occur as shown in the following tables:

At least one of the triggers must be true. The following table

shows the effect of OR on events with multiple triggers. In the ta-

ble, 0 indicates a false condition (not occurring) and 1 indicates a

true condition (occurring).

When using OR, if one or more (but not all) of the triggers go

false, the event logic is only acted on again when all triggers eval-

uate to false (result = 0).

AND

All triggers must be true. The following table shows the ef-

fect of AND on events with multiple triggers. In the table, 0 indi-

cates a false condition (not occurring) and 1 indicates a true con-

dition (occurring).

XOR

At least one trigger, but not all, must be true. The following table

shows the effect of XOR on events with multiple triggers. In the

table, 0 indicates a false trigger condition (not occurring) and 1

indicates a true condition (occurring).

Managing Triggers in the Triggers List

Triggers in the list can be edited, duplicated and deleted.

Editing Triggers

To edit a trigger:

1 Double-click the trigger in the Triggers list. Or, right-click the

item in the list and choose

Edit.

2 Do any of the following:

• To change the trigger type, click the

Type pop-up menu and

make a new selection from the Type menu.

• For

Fader Above or Fader Below triggers, click the cur-

rently displayed

dB value to highlight it, then type in a new

value.

• For switches, buttons and other two-state functions, click

the

State pop-up menu and make a selection. Choices for

State vary as appropriate for the trigger type, and will in-

clude Closed or Open, On or Off, and Pressed or Released.

3 To confirm your changes, press Enter or click anywhere else in

the Events window.

Selecting Triggers

Triggers can be selected using the same methods as used when se-

lecting items in the Event list. For more information, see “Select-

ing Events” on page 217.

Duplicating Triggers

To duplicate a trigger:

1 Select one or more items in the Triggers list.

2 Right-click on any selected item and choose Duplicate.
