Catch, Link, and Hierarchy Buttons
Most windows contain Catch, Link, and Hierarchy buttons. These are used to tie or
associate Logic Express windows, and can aid in navigating through different levels of
your song structure. As an example of where this is useful, if you click on a MIDI region
in the Arrange area, the contents of a linked window (the Piano Roll editor, for
example) will update immediately to show the events within the region.
Scroll Bars
Vertical and horizontal scroll bars are shown at the right and bottom edges of the
window. These enable you to view sections that fall outside the visible display area.
Zoom Sliders
Vertical and horizontal sliders are shown at the bottom right corner of the window.
These allow you to horizontally or vertically resize the contents of the window,
enabling a closer or more distant view of data.
Bar Ruler
All linear editing windows feature a Bar ruler at the top. The position of regions and
events within a project are aligned with Bar ruler positions. The Bar ruler displays
markers and locators, and reflects time signature changes. It also indicates three
important operational modes—solo, recording, or synchronized.
