Lock the solo status of regions
1 Option-click the Solo button in the control bar (or press Option-S).
2 Select the regions you want to solo.
Selecting regions while the project plays does not affect their solo status.
3 When you’re finished, click the Solo button (or press S) again.
Muted tracks and regions appear slightly differently in the Tracks area, depending on how they
are muted:
•
When a track is muted using its Mute button, the regions on the track are gray, but the region
names are in color.
•
When a track is turned off using its On/Off button, both the regions on the track and the
region names are gray.
•
When an individual region is muted, the region and its name are gray, and a small colored dot
precedes the name.
•
When a track is muted because another track is soloed, the regions on the track are gray, but
the region names are in color.
Time stretch regions in the Tracks area
When you resize regions, the position of notes and other events in the regions does not change.
Alternatively, you can time stretch regions to shorten or lengthen the relative distance between
events in the regions. Expanding regions increases the distance (the amount of time) between
events in the regions, while compressing regions decreases the distance.
For example, you can make a region play in half time by stretching it to twice its original length,
or play in double time by shortening it to half its original length.
You can also time stretch individual notes, chords, and other items in audio regions using Flex
Time. For more information, see
Flex Time and Pitch overview .
Time stretch MIDI regions
m Option-drag the left or right edge of one or more MIDI regions.
The events within the region are stretched or compressed, proportionately, by the amount that
the MIDI region is altered in length.
Time stretch or compress audio regions
m Option-drag the right edge of an audio region.
This action stretches or compresses the audio by the amount that the region is altered in length,
and replaces the original region with a new PCM audio file (in the original file format, or AIFF, if
the original was not PCM).
Time stretching is limited to the value of the current Tracks area grid setting (in the Snap pop-up
menu).
