Synchronization settings
General Synchronization settings
General Synchronization settings are only available when Show Advanced Tools is selected in
Advanced preferences.
General Synchronization settings are used when running Logic Pro as a slave—when Logic Pro is
being controlled by another device.
•
Sync Mode pop-up menu: Defines the master (timecode type) that Logic Pro is synchronized to.
•
Internal: Selects the internal timer of Logic Pro, with Logic Pro running as the master. External
devices can be synchronized via MIDI Clock or MTC.
•
MTC: Selects MIDI Time Code mode, with Logic Pro running as a slave. MIDI timecode can
either arrive at a MIDI In port, or be generated by a MIDI interface that translates it from
incoming SMPTE timecode—the Unitor8, for example.
•
Manual: Selects Tempo Interpreter mode, with Logic Pro running as a slave to impulses that
are recognized as valid beats by the Tempo Interpreter. The parameters that control how
Logic Pro responds to Tap Tempo commands can be found in the Tempo Interpreter window.
•
“Auto-enable External Sync and Tap Tempo” checkbox: When selected, Logic Pro 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 Pro automatically locks to the first synchronization signal it receives.
Important: Make sure that different synchronization signals don’t arrive simultaneously;
remember that there can only be one timecode master.
