846 Chapter 35 Synchronizing Logic Express
The Synchronization Master and Slave Relationship
In all synchronization situations, regardless of the simplicity or complexity of your
studio configuration, the following rules apply:
 There can only be one synchronization master.
 The synchronization master sends time code information (synchronization signals) to
one or more synchronization slaves.
Logic Express is capable of acting as master or slave, as are many devices.
Important: In many (if not most) cases, you will need to manually set each
synchronization-capable device—including Logic Express itself—to act as master or
slave. If you don’t do this, there will be multiple master devices in your system, which
will result in synchronization errors.
Using External Synchronization
When you first open Logic Express, manual synchronization mode is automatically
switched off—and Logic Express is in Internal Sync (master) mode. Activation of the
Transport bars Sync button synchronizes Logic Express to the chosen synchronization
source.
If Logic Express is running by itself (no devices or applications capable of
synchronization are in use), or is acting as the synchronization source, it is the
synchronization master device. In this situation, the Transport bars Sync button should
not be activated.
The Transport bar Sync button is not displayed by default.
To view the Transport bar Sync button:
1 Control-click on the Transport bar, then choose Customize Transport Bar from the
shortcut menu.
2 Activate the Sync checkbox towards the bottom of the Modes and Functions column
(right-hand column), and click OK.
