Chapter 35 Synchronizing Logic Express 847
Using the Sync Button
You can use the Sync button to turn external synchronization on or off at any time,
without changing the selected synchronization source. This allows you to temporarily
disengage Logic Express (running as a slave) from an external synchronization master
device. This could prove useful if you need to quickly edit a MIDI region while the
external synchronization source (tape machine, VTR, and so on) is still running, for
example.
When Logic Express Is Running as a Slave
The Transport bar Sync button is lit/depressed, when active.
Click the upper (MIDI In) section of the MIDI Activity display—while receiving an
external synchronization signal—to view the frame rate of incoming MIDI time code.
Note: When you click the Record button during external synchronization, Logic Express
enters record mode, but does not actually start recording until it detects an external
time code signal.
Accessing Synchronization Settings With the Sync Button
Control-click the Transport bar Sync button to open a shortcut menu, where the
following options are available:
 Setting the type of external synchronization.
 Determining whether or not MMC commands (see “MIDI Machine Control” on
page 861) should be transmitted by the Transport buttons of Logic Express, allowing
remote control of MIDI-controlled tape machines.
 Direct access to the Synchronization settings.
 Direct access to the tempo editors (see “Advanced Tempo Operations” on page 667).
