Click-hold the specific position unit, and drag vertically. Release the mouse button when
you’re done.
If another editor, such as the Piano Roll Editor, is open, you will see the note event move

automatically resorted. The currently selected event remains highlighted.

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) column.
You cannot directly alter the event type in the Status column.
To alter the event type
Do one of the following:
µ
Choose Functions > Transform to open a Transform window, and transform the event.
See Editing MIDI Events in the Transform Window .
µ
Add an event of the new type, and delete the original event.
