Rounded to Whole Bars
The MIDI > Snap Region Start to Bar function rounds the Region startpoint to the
nearest whole bar.
The position of events within MIDI Regions is not affected by changes to the Region
length.
If you wish to alter the position of the events:
m Hold down Option while altering the length of a MIDI Region to alter the timing of
events. The events will be stretched or compressed, proportionately, by the amount
that the MIDI Region was altered in length.
Note: You can make a rhythmic MIDI Region play in “half-time” by stretching it to twice
the original length, or in “double-time” by shortening the length to half the original
length.
… to Adjust It to Fit Its Contents
The MIDI > Set Optimal Region Sizes function reduces or increases the length of a
Region, making it just large enough to contain the events (or Regions, if a Folder)
within it. The Region borders are rounded to the nearest bar.
Holding down Option when using this function rounds the borders to the nearest beat.
… to Adjust It to Fit Other Regions
The Region > Remove Overlaps function searches all selected Regions in a track for
overlaps. If an overlap is found, the earlier Region is reduced in length, thus removing
the overlap.
… to Adjust It to Fit Song Position
You can move the start or end point of a selected Region to the Song Position Line, by
use of the following key commands:
• Set Object Start to SPL Position
• Set Object End to SPL Position.
The use of Set Object Start to SPL Position is only possible when the Song Position Line
(SPL) is placed before the start of the Region. Similarly Set Object End to SPL Position
only makes sense if the SPL is placed after the end of the Region. If not, the length of
the Region will be shortened to one format (Snap) value.
