Chapter 18 Editing MIDI Events in the Event List 445
Changing the Appearance of the Position and Length Columns
Not every project is bar/beat oriented. These View menu commands may make
changing the position and length of events much easier when you’re working with film
or video, for example.
 View > Event Position and Length in SMPTE Units: Choose to display the position and
length columns in SMPTE units.
 View > Length as Absolute Position: Allows you to make the length display show the
absolute position of the note off event, rather than its length from the note on
position.
 View > Relative Position: If active, the event positions don’t refer to their absolute
location within the project, but to their relative positions within the MIDI region
(their distance from the start of the MIDI region).
Altering Event Values
Event parameter values can be changed by using the mouse as a slider or with text
input, as per changes to position or length—on the values shown in the Val(ue),
Num(ber) or Ch(annel) columns.
You cannot directly alter the event type in the Status column.
To alter the event type, either:
m Choose Functions > Transform to open a Transform window, and transform the event.
See Chapter 20, “ Editing MIDI Events in the Transform Window .”
m Add an event of the desired type, and delete the original event.
If a parameter of one of several selected events is altered, it will affect the same
parameter in all events within the selection group. When you alter parameter values in
a group of selected events, the relative differences between parameter values remain
unchanged.
Parameter values can only be altered until the (same) parameter value of one of the
selected events has reached its maximum or minimum value.
To override the maximum or minimum value limitation:
m Option-drag on the value, or press Return to confirm a numerical input.
This allows you to continue altering a parameter value in a multiple selection, even
when one of the selected events has reached its maximum or minimum value.
To set a parameter to the same value for all selected events:
m Hold Shift-Option, while using the mouse as a slider, or press Return to confirm a
numerical input.
