850 Chapter 35 Synchronizing Logic Express
General
The General tab of the Synchronization project settings offers the following
synchronization parameters (used when running Logic Express as a slave).
Sync Mode
This parameter defines the master (time code type) that Logic Express is synchronized
to:
 Internal: The internal timer of Logic Express. Logic Express is the master. External
devices can be synchronized via MIDI Clock or MTC (the relevant settings are made in
the MIDI tab).
 MTC: MIDI Time Code mode. Logic Express runs as a slave. MIDI time code can either
arrive at a MIDI in port, or be generated by a MIDI interface that translates it from
incoming SMPTE time code (the Unitor8, for example).
 Manual: Tempo Interpreter mode. Manual synchronization or human sync mode.
Logic Express runs as a slave to impulses that are recognized as valid beats by the
Tempo Interpreter. The Tempo Interpreter can be controlled by MIDI events, or a key
on the computer keyboard. See “
Using the Tempo Interpreter ” on page 679.
Auto Enable External Sync
When this option is activated, Logic Express runs as the master (Internal sync mode),
until it receives a synchronization signal—either in the form of MTC, or from the Tempo
Interpreter.
Logic Express automatically locks to the first synchronization signal it receives.
Important: Ensure that different synchronization signals don’t arrive simultaneously—
remember that there can only be one time code master!
