Jog/Scrub Wheel Zone
The Jog/Scrub Wheel and SCRUB button can be used to navigate through the project,
which is useful for a number of Transport tasks. Simply turn the dial to use it. The
following Scrub modes change the behavior of the Jog/Scrub Wheel.
 Scrub mode off: The Jog/Scrub Wheel moves the playhead.
 Scrub mode on: The Jog/Scrub Wheel performs scrubbing, which allows you to hear
the data of the selected (or solo-ed) tracks while scrolling/moving through the
project.
Audio tracks are normally played back at their original speed. If you would prefer to
hear them at double speed, choose Logic Express > Preferences > Audio > Devices,
and set Maximum Scrub Speed to Double in the pop-up menu.
Note: You can also use the SCRUB button for Pause functionality.
 SHUTTLE mode (Scrub button LED flashing): the Jog/Scrub Wheel shuttles the
playhead—turning it increases or decreases the speed of playhead movement.
