330 Chapter 13 Creating Your Arrangement
Adjusting the Grid to Zero Crossings
If Audio > Search Zero Crossings is turned on, any length adjustments to audio region
start or end points will snap to the nearest zero crossing point of the waveform.
The disadvantage of this option is that altered start or end points never land exactly on
the selected musical grid.
Should this ever cause a problem, you can simply switch off the Audio > Search Zero
Crossings setting. The primary reason for activation of the Search Zero Crossings
setting, is that it prevents clicks and pops at region start and end points.
Adjusting the Start or End Point of MIDI Regions
You can move the left corner beyond the first event in a MIDI region—which 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 where 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 grid (based on bars), as this would
make arrangement far more complicated.
Note Handling Options When Changing MIDI Region Lengths
The Clip Length setting in the Extended Region Parameters (only visible if the View >
Extended Region Parameters setting is turned on in the Arrange area) 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 originally a different size.
To make all selected regions the same absolute length:
m Hold Option-Shift while changing the length with the Pointer tool.
