Apple logic pro 8 Manual

 

The Content Link function is now activated by Option-clicking the Link button (double-
click still works). Control-click (or click-hold) the button to access a shortcut menu, 
offering:  No Link, Same Level Link, and Content Link modes.

 

The Piano Roll Editor Link button now provides only two states:  On and Off. On 
behaves as follows:

Â

 

If you select a single region in the Arrange area, the Piano Roll Editor only displays 
the content of this region—with start and end markers shown in the Bar ruler.

Â

 

If you select multiple regions in the Arrange area, the Piano Roll displays the contents 
of all selected regions.

The new behavior makes the Piano Roll Editor’s Hierarchy button and Show Selected 
Regions Only setting obsolete, so they were removed. 

 

The Hyper Editor Link button now provides only two states:  On and Off. Switching it 
on activates Content Link:  The Hyper Editor always displays the content of the region 
selected in the Arrange area. The display updates whenever the selection changes.

The new behavior makes the Hyper Editor’s Hierarchy button obsolete, so it was 
removed. 

Further to these changes, the Arrange level view in both the Piano Roll Editor and 
Hyper Editor was removed, as it serves no purpose in the new interface.
