Adjusting the Start or End Point of MIDI Regions
You can move the left corner beyond the first event in a MIDI region. This action hides
events from the beginning of the MIDI region, but these hidden events will continue to
play back.
If you actually want to remove the information from the start of a MIDI region, you need
to cut it and mute or delete the new start segment (new MIDI region).
The hide facility is useful in situations in which you might want to trigger MIDI controller
events (such as sustain) before the musical phrase begins, but do not want to use a MIDI
region that doesn’t fit into the current Arrange area grid (based on bars), as this would
make arrangement far more complicated.
The Clip Length setting in the Inspector’s Region Parameter box determines whether:
• Notes sounding when the region ends are abruptly cut off (active).
• Notes should be played to their normal end point (inactive: default), regardless of
where the region ends.
The point of this function is to allow you to alter the length of the last notes in a region
directly from the Arrange area, by adjusting the length of the MIDI region. Clip length
has no effect on folder regions.
Making Multiple Regions the Same Length
You can change the length of multiple regions to the same absolute amount, making
them the same length, even if they were originally a different size.
To make all selected regions the same absolute length
µ
Hold Option-Shift while changing the length with the Pointer tool.
Setting Region Start and End Points to the Playhead Position
You can move the start or end point of a selected region to the current playhead position
with the following key commands:
• Set Region/Event/Marquee Start to Playhead Position
• Set Region/Event/Marquee End to Playhead Position
Note: The anchor point is also moved when using Set Region/Event/Marquee Start to
Playhead Position on an audio region.
Adjusting Region Lengths to Fit Other Regions
On occasion, you may want to reduce or extend the length of all regions on a track, or
between locators, ensuring that they directly adjoin each other without gaps.
