Chapter 13 Creating Your Arrangement 313
3 Grab the playhead in the Arrange or Bar ruler, and move it back and forth through the
parts of the project you want to hear, at the speed you want to scrub the section (or
use the Scrub Rewind and Scrub Forward key commands).
Audio and MIDI data playback is perfectly synchronized when scrubbing.
Note: Scrubbing is automatically activated when you’re dividing regions (with the
Scissors tool) in the Arrange, making it easier to identify the cut position.
Scrubbing Particular Regions
The following list outlines the relationship between scrubbing and region selection:
 If no regions are selected, all regions are scrubbed.
 If you select a specific audio region, only it will be scrubbed.
 If you rubber-band or Shift-select audio regions on different tracks, only the selected
audio regions are scrubbed.
 MIDI regions (software and external MIDI) are always scrubbed, regardless of the
selection status (provided that the Scrubbing with Audio in Arrange project setting is
active).
 The Mute or Solo (see next section) status of all tracks and regions has an effect on
what you hear when scrubbing, so you can make use of them to scrub audio parts in
isolation (or with particular software or external MIDI instrument tracks).
MIDI Controlled Scrubbing
The Scrub by MIDI value (-2-) function (available in the Controller Assignments Editor;
see the Logic Express 8 Control Surfaces Support manual) is designed to allow scrubbing
via external MIDI control. You can assign any MIDI controller number to this function.
Data bytes over 64 scrub forwards, and those under 64, scrub backwards.
Muting Regions
Often, when arranging, you’ll want to test musical ideas by muting certain regions.
To mute or unmute individual or selected regions, do one of the following:
m Select the Mute tool, then click the desired regions with the Mute tool.
m Select the desired regions with the Pointer tool, then use the “Mute/unmute selected
Notes/Regions/Folders” key command (default: M).
