Changing Event Values
Events can be altered individually or as a group. When adjusted as a group, the
absolute differences between the event values remain constant.
To alter individual event values:
m Grab the event beam (with the Pointer or Pencil tool), and drag vertically.
The current value is shown in a help tag as you drag.
To alter several contiguous event values:
m Drag across the events with the Pointer tool.
The current value is shown in a help tag as you drag across each event.
To alter the values of multiple events:
1 Use any of the selection techniques discussed above to select the events you want to
edit.
2 Grab one of the grouped (and highlighted) beams, and drag vertically.
The values of all events are adjusted. If any of the beams in the group reaches the
maximum or minimum value, you will not be able to go any further in that direction.
To adjust event values when one grouped event has reached an extreme value:
m If you hold Option while doing so, you can keep raising or lowering the values of all
events in the group, until the grabbed event beam reaches the maximum or minimum
value.
Moving and Copying Events
Events can be moved or copied to other positions in the same, or other, lanes. When
moved or copied between lanes, the event values are retained, but are converted to
the target event definition. As an example, moving several events from the Volume
lane into the Pan lane will result in the Volume values being used for Pan position
changes.
To move selected events:
m Hold Shift, and drag to the desired position and lane.
As you do so, a help tag will inform you of the position, event definition type and value
(if applicable).
